<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】 The purpose was to provide a fast and accurate method for the identification and counting
of mature citrus in natural environment, to solve the shortage of high cost, long time and low precision caused by manual
sampling method, and to lay a foundation for automatic picking of citrus in the future. 【Method】 The RGB camera was
used to collect the image of the citrus fruit tree, and the image was converted to Lab color space. The“a”component was
used for the citrus distinguishing from the background color, and then the MATLAB software was used to count the citrus
based on Hough circle transformation method to achieve an estimate of the citrus yield. 【Result】 The image processing
method is simpler and faster than the traditional method of fruit and background separation. The recognition accuracy
rate is 94.01%. Yield estimation accuracy is 96.58%, and the average recognition time is 1.03 seconds. The algorithm
was tested on 20 images(10 trees), and the number of fruits counted by this algorithm was compared with that counted by human observation. The coefficient of determination (R2) is 0.83. 【Conclusion】 The method can realize rapid and automatic
identification and counting of fruits and has good robustness to fruit overlap and fruit occlusion. This research promotes the
application of machine learning in modern agriculture, has a high theoretical and practical significance, and facilitates the
further development of orchard smart agriculture.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=201907023&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】 The study was to grasp the fluctuations of mutton price among different regions in China,
and develop scientific and reasonable price control policies to promote the healthy development of China's animal husbandry.
【Method】 With the quarterly data from March 2000 to September 2018, mutton price of main production area, main
selling area and the national mutton market price were constructed as panel data of the price series, regional difference
analysis of three price series was conducted by using panel vector autoregressive model (PVAR). 【Result】 Except for
the main producing area of Heilongjiang Province, mutton prices of the main producing areas and the main selling areas
have a bidirectional causal relationship with the national mutton price. The fluctuation of mutton prices in the main producing
area and the main selling area has significant influence on the national mutton price. Compared with other provinces, Inner
Mongolia, Sichuan and Shanghai have a leading role in the formation of the national mutton market price; the contribution rate
of mutton price fluctuations in the main producing areas is generally higher than that in the main selling areas, and the price control policies cannot be imposed in all areas and should focus on mutton production. 【Conclusion】There is a great regional
difference between the mutton price in the main producing area and the main selling areas, and regional differences need to be
consider for the control policy of mutton price. The government should focus on strengthening support policies at the supply level,
improving information release and early warning mechanism for the mutton market, and perfecting the traceability system for the
entire industrial chain of the main production areas and main selling areas to ensure the sound operation of the mutton market.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=201906022&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The minimum purchase price policy is an important policy to promote the development 
of agriculture in China. Through the empirical research on the influence of the minimum purchase price policy on the 
phenomenon of "the number of production, imports, and stocks increased simultaneously" of rice, this paper provides 
a reference for the supply side structural reform of agriculture in China.【Method】Taking the data from 2002 to 2016 
as the sample, the effects of the minimum purchase price policy on rice production, imports and stocks were studied by 
simultaneous equations.【Result】The results show that the minimum purchase price promoted the yield increase by 
affecting the area planted with rice in China and the annual increase of rice production is about 6%. The minimum purchase 
price policy significantly promoted the increase of domestic rice prices in China with an average annual increase of about 
36.3%, and significantly promoted the increase of rice imports in China. The policy of minimum purchase price promoted the 
increase of rice stock in China by affecting the supply and demand.【Conclusion】China is in the critical period of adjusting 
the policy of minimum purchase price of rice. It is suggested that the minimum purchase price should be adjusted flexibly,the balance of agricultural support policies should be kept well, and more efforts should be made to improve the international 
competitiveness.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=201905020&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】 Cassava is an important starch and energy crop in China. At present, its production mainly 
relies on manual labor, which causes high production cost and low economic profit. The cassava harvesters developed 
in recent years seldom matched with equal row spacing cultivation mode adopted currently. While harvesting with these 
harvesters, tractor wheels inevitably crush on cassava rows and cassava roots are destroyed, which resulting in a root loss 
rate of up to 17%.【Method】In order to avoid row crushing and increase root harvest rate, according to the requirements of 
mechanized harvesting and the wheel size of a 66.2 kW tractor, a cultivation mode of wide and narrow double-row ridging planting was designed with wide row spacing being 120 cm, narrow row spacing being 60 cm, and ridge height being 25-30 cm. 
A cassava ridger and a cassava combined planter matching the planting mode were developed, and adaptability experiments 
were carried out in different producing areas including Guangdong, Hainan, Guangxi and Yunnan.【Result】With the wide and 
narrow double-row ridging cultivation mode, the ridging efficiency was 0.6-0.8 hm2/h, the planting efficiency was about 0.6-0.7 
ha/h, the efficiency of mechanized planting was 23 times higher than that of manual planting and the cost of mechanized planting 
was only 50% of manual planting. The cassava yield(under mechanized planting) was 33-42 t/hm2. Mechanized harvesting 
with this planting mode could effectively avoid row crushing and significantly reduce root broken rate, with the loss rate of less 
than 5%.【Conclusion】The study showed that the wide and narrow double-row ridging cultivation mode can be well suited to 
mechanized planting and harvesting and promote the high integration of agricultural machinery and agronomy.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】A segmentation algorithm of overlapping elliptical leaves in a complex background was 
proposed.【Method】Firstly, the main body of the overlapping leaves and part of the green background was segmented 
through the super-green algorithm. The body of the overlapping leaves was selected by selecting the maximum connected 
area. The concave point of overlapping parts and the tips of the leaves were obtained via pit detection and bump detection 
after removing the petiole. The line defined by the two tips of upper-layer leaf and the edges of the non-overlapping areas 
of the upper leaf was overturned to the overlapping area as the initial point of the greedy algorithm to find the edge of the 
overlapping area.The edge of the target leaves could be obtained so that the upper leaves were segmented correctly through 
smoothing and convex hull processing on the obtained edges. As for overlapping lower leaf, the uncovered area of the lower 
leaf could be obtained by subtracting the upper blade segmented from the entire overlapping leaf. The complement of the 
lower leaves could be obtained through inverting half of the lower leaf with the line formed by its tips as the symmetric axis.
【Result】The proposed algorithm can segment elliptical overlapping leaves in a complex background, with the average error rate below 3.0%. 【Conclusion】Aiming at the segmentation of overlapping elliptical leaves in complex background, the 
greedy algorithm combined with bump detection and pit detection can segment target leaf more accurately, and the average error 
rate is below 3%, scilicet, the segmentation accuracy is above 97%.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=201905022&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The support of the state for the financial development of pastoral areas and the demand of 
pastoral households for capital turnover making the loan of pastoral areas more common. Loans mean that herdsmen need 
to be able to repay capital and interest. Therefore, the evaluation of herdsmens’ ability to repay their debts can provide 
some basis for improving the development of pastoral areas by the state. 【Method】By using literature review method 
and descriptive statistical method, this paper analyzed the current situation of herdsmens’loan and production and life in 
Xilingol League. Based on the field survey data, the debt-paying ability of herdsman households was evaluated by deductive 
reasoning of the herdsman's cash flow and income function. 【Result】The herdsmen of pastoral areas have low repayment 
ability, and relatively high interest paying ability. The unequal cash inflows and outflows reduced the solvency of herdsmen. 
From 2015 to 2017, the actual number of livestock was less than that when the balance of income and expenditure was 
balanced. The profit generated by herdsmen was zero, the herdsmen were in a loss state, and the herdsmens’ ability to pay 
debts was weak. 【Conclusion】 For the herdsmen with large livestock breeding scale or market scale, the loan quota can be 
increased moderately, on the contrary, loan quota should be reduced. The loan period of the financial institutions should be 
changed flexibly. It is suggested that the government should provide external financial support to herdsmen and subsidize in 
due course to alleviate the borrowing pressure of herdsmens and enhance their debt-paying ability.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The high-quality development of agriculture is the direction of China’s agricultural 
development. As a large agricultural province, Guangxi adheres to the high-quality development of agriculture, which is conducive to improving the level of agricultural modernization in Guangxi. Based on the analysis of industrial structure and 
aggregation in Guangxi, and this paper explores the high-quality development path of Guangxi agriculture, and provides 
theoretical references for the high-quality development of Guangxi agriculture.【Method】 The 14 cities in Guangxi were 
divided into two grades, and the fixed effect model was used to study the upgrading rate of industrial structure, the optimization 
rate of industrial structure, the degree of regional specialization and the factors affecting the upgrading of industrial structure 
in Guangxi during 2013—2017. 【Result】 Beihai City, Fangchenggang City and Qinzhou City was developed relying on 
Beibu Gulf, the industrial structure upgrading rates of the three cities are more than 50%, and the industrial structure has the 
highest growth rate of 363%. The average values of optimization rate of the primary industry structure and the dominant areas 
are above 2%. Through the fixed effect model processing of independent variables by Eviews, it is found that there is significant 
heterogeneity in the industrial upgrading trend in various regions of different grades. The optimization and aggregation of 
industrial structure and the improvement of labor quality are the key points to the high-quality development of agriculture. The 
investment in agricultural mechanization and infrastructure has a significant impact on the excellent and inferior areas, which 
is the basis for the high quality development of agriculture.【Conclusion】 It is suggested to reduce the differences in regional 
industrial structure upgrading by coordinating the comprehensive development of different areas, to accelerate the cultivation 
of productive technical service subjects and provide large-scale high-quality agricultural technology services, to improve 
the optimization and concentration of industrial structure and the quality of labor force, to facilitate the application of the 
combination of agronomy and agricultural machinery, and strengthen infrastructure construction for the promotion of the highquality development of agriculture.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The traditional iodine colorimetry method requires complex and time-consuming
pretreatment and experimental preparation. The near-infrared detection method not only has the advantages of simple
operation and rapid detection, but also does not consume reagents, samples and standards, which greatly reduces the
detection cost. This paper aimed to establish a near-infrared detection model suitable for the starch in Jiangxi flue-cured
tobacco based on Jiangxi flue-cured tobacco samples. 【Method】The near-infrared spectra and corresponding continuous
flowing analyzer detection data(iodine colorimetry) of 650 flue-cured tobacco samples from 21 districts and counties in
Jiangxi Province were collected, then the detection model was established by using different regression methods and data
processing methods with the spectral data and chemical analysis data in one-to-one correspondence, and the best model
parameters were determined by comparing their root mean square(RMS) errors and correlation coefficients. 【Result】A
starch content prediction model suitable for Jiangxi flue-cured tobacco was established. The RMS errors of calibration and
the prediction were 0.407 and 0.490 respectively, and the correlation coefficient was 96.52%.The model was verified by
external samples and the errors of 95% of the samples were within 10%. 【Conclusion】The model reduced the detection
cost and improved the analysis efficiency, which could be used for the rapid detection of the starch content in Jiangxi fluecured tobacco samples and replace the traditional iodine colorimety method to a certain extent .]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=201903022&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】 The study was to understand the input-output and cost-benefit of rice production and
farmers’ willingness to grow rice in Guangdong Province. 【Methods】 The microscopic farm household data was obtained
through field survey and farmers’ production situation and production willingness were analyzed by using descriptive
statistics and qualitative analysis.. 【Results】At present, rice production in Guangdong Province is facing severe aging and
farmers’ engagement in non-agricultural sectors. The average farmland scale is small and fragmented. Under the premise
of considering labor and land costs, farmers’ rice production is generally facing losses as labor accounts for the largest
part of rice production costs and more labor force is needed in the transplanting and post-harvest process. The purpose of
farmers’ rice production is mainly to meet the needs of the family and they have limited understanding of national grain
support policies. With the increase of age, the farmers tend to withdraw from the rice production obviously. 【Conclusion】
Due to the low efficiency and profit of rice production in Guangdong, farmers have poor initiative in rice production. Land
transfer and promotion of high-quality varieties are important measures to form large-scale, specialized and high-quality
rice growers for the improvement of quality and efficiency of rice production in Guangdong.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Under the background of the country’s implementation of rural revitalization strategy, promoting the
integration of primary, secondary and tertiary industries in fishery industry is an inevitable requirement to comply with
the new situation of fishery development, and is also an effective way to adjust the structure of fisheries and realize the
transformation and upgrading. The new management entities are important organizational carriers to realize the integration of
fishery industry, and have been a great force to promote the integration of fishery industry and enhance the competitiveness
of fishery industry. At present, the number of new fishery management entities in China has maintained a relatively rapid
growth. In 2017, the growth rate of fishermen professional cooperatives was 11.7%, and that of fishery family farms was
23.3%. Moreover, the characteristics of industrial integration of new fishery management subjects were more prominent,
with significant demonstrating and driving effects, However, the overall number of new fishery management entities still
accounted for a small proportion and there were great regional differences in its development. Based on the elaboration of
the relationship between the new management entities and the integration of fishery industry, this paper analyzed the main
problems existing in the promotion of the industrial integration of the new management entities, and proposed that it is
supposed to improve the benefit affiliating mechanism of relevant entities in the industrial integration, optimize the external
support environment of the industrial integration and enhance the ability of scientific and technological innovation and
application of new fishery management entities, play the leading role of new management entities fully and stimulate their vitality for pushing the integration of fishery industry.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】A quantitative research of landscape pattern characteristics and spatial differences was
conducted so as to provide a basis for the optimization of scientific layout of basic farmland and land space planning.
【Method】Based on the basic farmland of typical southwestern plateau mountain region in Yunnan Province, taking
different spatial scales such as provincial and municipal areas into comprehensive consideration, and in view of
comprehensive analysis of basic farmland quality, slope and land types, the landscape ecological theory method was
combined with the GIS spatial statistical analysis method.【Result】Dehong Prefecture had the highest grade of farmland
quality at 8.49, while Nujiang Prefecture had the lowest grade at 11.70, with the highest number of combinations of cultivated land types being 5. The basic farmlands were distributed in a fragmentary landscape pattern at the provincial scale.
Dehong had the highest diversity index at the municipal scale, i.e. 2.0612, while Nujiang had the lowest index, i.e. 0.6215.
According to the dominance, uniformity and concentration index, Dehong, Xishuangbanna, Dali and Yuxi, among others, had
high quality, highly diversified and uniformly distributed basic farmlands; the global Moran's I index of the basic farmland
landscape pattern index and the farmland quality were 0.2052 and 0.0310, respectively, while that of the basic farmland
area ratios was 0.6046. Qujing had the highest Moran's I index at the municipal scale, i.e. 0.8145, while Zhaotong had the
lowest index, i.e. 0.3541.【Conclusion】The basic farmlands in the southwestern plateau mountain region are distributed
in a fragmentary landscape pattern. with great quality difference and few high-quality basic farmlands. The basic farmlands
have weak quality correlation at a provincial scale, but strong spatial autocorrelation at a municipal scale, with a cluster
distribution of local spatial autocorrelation similar to kernel density distribution. The areas with high kernel density value
have positively correlated spatial relations, while those with low kernel density have negatively correlated spatial relation.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=201902023&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】 To find out the input-output efficiency of family farms and formulate targeted measures
for their future development. 【Methods】The survey data from 79 family farms in 14 prefecture-level cities in Shandong
Province was used and a three-stage DEA analysis method was adopted to analyze the production efficiency of grainbased family farms in Shandong Province.【Results】Upon the SFA-like regression analysis, the effects of environmental
factors and random disturbances on the production efficiency of family farms were removed. Compared with the first
phase, the average total technical efficiency value of family farms in the 14 cities increased from 0.815 to 0.862 and the
pure technical efficiency value increased from 0.877 to 0.962, while the returns to scale decreased from 0.923 to 0.895.
Among the environmental factors, the rural residents’ disposable income had a negative impact on the production
efficiency of the family farms while farmers’ education level had a positive effect, and the fiscal policies played an
insignificant role. 【Conclusions】The environmental factors and random factors do have an impact on the production
efficiency of family farms. Therefore, such external influences shall be removed from efficiency estimate. According to the impact of environmental factors on the development of family farms, the government should guide farmers to make correct
investments, increase financial support, strengthen farmers’ training, and improve the construction of agricultural socialized
service systems.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Soil and water resources are the two major resources for agro-ecosystem, which influence its sustainable 
developments.【Objective】The objective of this study is to explore the impact of changes and developments of Heilongjiang 
agro-ecosystem on the utilization of water and soil resources.【Method】The crop water consumption and planting area 
of Heilongjiang agro-ecosystem were evaluated and predicted under the current management level of agricultural science 
and technology by using Logistic model and RMSE analysis model.【Result】The results showed that the K value of crop 
total planting area in Heilongjiang agro-ecosystem is about 14.3 million hm2, and the K value of agricultural water supply 
is about 316 million m3. The K value of rice per unit yield was about 7 030 kg/hm2, while the K value of grain crops per unit 
yield was about 5 275 kg/hm2, and the K value of crop total yield capacity reached 75.32 million tons. Meanwhile, by using 
this model, it can be seen from the fitting analysis on the simulated values and statistical values of the total amount of water resource irrigation, crop total planting area and crop per unit yield that the minimum and maximum values of the determination 
coefficient (R2) were 0.89 and 0.98, respectively. Moreover, almost all the Root Mean Square Error (RMSE) were less than 10%,

spatial distribution of the Tibetan settlements in the upper reaches of the Minjiang River.【Method】The land use data in 3 
years (1995, 2005, 2015) were used to simulate and predict the land use in 2025 in the upper reaches of the Minjiang River 
by using CA-Markov model .【Result】 The results showed that: (1) During the period of 1995—2005, the woodland area 
decreased significantly, but other land use increased. The dynamic degree of construction land showed a highest fluctuation 
with the total area increased by 139.52 hm2, while the growth rates of construction land and bare land were 92.16% and 
25.72%, respectively. (2) During the period of 2005—2015, only the construction land area increased tremendously, and 
the dynamic degree of which showed a highest fluctuation with the total area increased by 1 943.03 hm2, while other land 
area decreased and the dynamic degree changed little. (3) During the period of 2015—2025, the use of bare land and dry 
land began to increase. While woodland and grassland had decreased by 1 735.45 hm2 and 1 367.14 hm2, respectively. The 
decreasing parts of woodland and grassland were changed to construction land and bare land. (4) During the whole study 
period, the proportion of different types of land in the study areas changed little, and the number of construction land, bare 
land and dry land increased slightly. 【Conclusion】The simulation results were feasible, which could well reflect the dynamic change trend of land use in Tibetan settlements in the upper reaches of Minjiang River, and provide some guidance for

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】To explore the relationship between farmland management scale and food production cost 
efficiency. 【Method】Based on the micro-farm household data surveyed by Jiangsu Provincial Price Bureau from 2012 
to 2016, this paper use the stochastic frontier cost function to measure the cost efficiency of rice production, then explored 
the relationship between farmland management scale and cost efficiency. On this basis, explore the way to improve cost 
efficiency. 【Result】The average cost efficiency of rice production in Jiangsu Province is 0.904, and with agricultural land 
scale increase, the rice cost efficiency shows an “inverted U-shaped” trend. The highest cost efficiency of rice production 
is at 3.64hm2, when the agricultural land scale reaches the most advantageous scale, the agricultural land scale will continue 
to increase and the rice cost efficiency will decline rapidly.The scale of agricultural land management, characteristics of 
agricultural decision makers, input of production factors, and proportion of agricultural employment selected in this paper have significant effects on rice production cost efficiency. 【Conclusion】There is no simple linear relationship between the 
farmland management scale and cost efficiency, but the “inverted U-shaped” relationship of increasing and then decreasing. 
Finally, from the aspects of farmland infrastructure construction, mechanized production and specialized production to put 
forward relevant suggestions to improve the cost efficiency of rice production.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=201901022&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】This paper analyzed the influencing factors of farmer's cultivated land transfer and explored 
a more effective guiding mechanism to promote the cultivated land circulation. 【Method】Based on confirmation of land 
right in rural areas, sampling survey and in-home interview of rural householders, methods of Logistic model and Tobit 
model were established. 【Result】The results showed that: (1) The cultivated land transfer market in the study area was 
relatively active. About 74% of the farmers participate in the circulation of cultivated land, and the rate of transfer-out 
cases were higher than that of the transfer-in. (2) Factors that significantly affect farmers to transfer-in the cultivated land 
include the number of part-time workers, the labor force, the cash crops planted and the agricultural insurance, each with a significance level of 90%; while factors that obviously lead farmers to transfer-out cultivated land were the age of the head 
of a household, the highest education level of a household, the annual income per capita, the per capita area of cultivated land 
and the agricultural insurance, each with a significance level of 90%. (3) The social security in poor mountainous areas could 
effectively avoid the risk of farmland circulation and activated the market of farmland circulation. 【Conclusion】In conclusion, 
the rural land transfer policy should be reformed reasonably for rural development and encourage the development of major 
agriculture-specialized households and family farms on the basis of improving the agricultural production skills of transferin households. At the same time, the non-agriculture households are encouraged to liberalize the cultivated land management 
rights on the basis of improving their cultural literacy and competence in non-agriculture employment.]]></description>

and fruits that are resistant to diseases and pests and have extended storage life. Age, unemployment and other occupations, 
income and information sources (newspapers/magazines) had a significant influence on the former. Factors such as 
gender, age, education level, civil servant and careers in public institutions, newspapers or magazines providing food 
information sources and descriptions of food packaging information components had a significant influence on the latter. 
Guangdong consumers lacked scientific knowledge related to genetic modification. Access to relevant GM food informationwas mainly through television broadcasts, newspapers and magazines. Consumer’attitudes towards GM fruits and vegetables are 
as follows: accepted (49% on average), neutral (27.8%) and opposed (18%).【Conclusion】GM vegetables and fruits will occupy 
nearly 50% of the market share and there are nearly 30% of the potential market to be developed. Management should focus on 
the popularization of relevant scientific knowledge and information release to promote the development of GM biotechnology and 
the production of GM food.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】In view of the serious agricultural pollution and the excessive application of chemical fertilizer 
in economic crops in China, taking apple production as an example, the optimal amount of fertilizer application for both 
economic and ecological benefits of apple was estimated.【Methods】The external cost and marginal output of chemical 
fertilizer were estimated by using dose effect method and secondary production function method.【Results】The results 
showed that the optimal economic fertilization rate considering ecological benefits was 932.55 kg /hm2, but it was prone to be 
affected by the change of market price. It would decrease with the increase of fertilizer price and increase with the increase 
of apple price. The external cost of chemical fertilizer was 0.73 yuan/ kg, and the pollution costs were expensive and ranked 
as: air pollution < soil pollution < water pollution.【Conclusion】The average fertilization intensity of apple in China meets 
the requirements of the best fertilization amount, but there are obvious regional fertilization differences in different apple 
production areas, and the problem of excessive fertilization is more serious in some apple production areas. Therefore, some 
suggestions such as reducing the financial policy intervention of chemical fertilizer, accelerating the promotion of soil testing 
formula fertilizer and establishing the ecological compensation system are put forward .]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=201912019&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The strategy and cost of weed control in the main tea producing areas of Guangdong Province 
were clarified, which provides a reference for the research, improvement and promotion of weed management technologies.【Method】Through questionnaire survey and field visits, the weed control methods, frequency, costs and expected costs 
adopted by tea enterprises (tea farmers) in the main tea producing areas of Guangdong Province，as well as the awareness 
and acceptance of green weed management technologies were investigated.【Result】The results showed that, in the main 
tea producing areas of Guangdong Province, the dominant strategy was artificial weeding (93.94%), followed by mechanical 
weeding (42.93%) and chemical weeding (8.59%), while green weeding control technologies such as straw mulching, weed cloth 
mulching and intercropping green manure only accounted for 4.55%-7.07%. The average annual cost of weed management was 
11 507.55 yuan/hm2 and the average frequency of weeding was 4.16 times. The average annual cost of weed management was 
expected to be 6 512.55 yuan/hm2. Among all weed control technologies，the annual average cost of weed control with pure 
chemical pesticides was the lowest(about 2, 805 yuan/hm2) and the annual average cost of pure artificial weed control was the 
highest (about 12 525 yuan/hm2). The costs of artificial weeding + green manure，artificial weeding + plastic film (weed control 
cloth) and other green weed control modes were between 7,500 and 8,985 yuan/hm2. The acceptance of green weed management 
technologies was 84%，while the actual utilization rate was less than 10%.【Conclusion】Artificial weeding with high cost is 
the dominant weed control method in the main tea producing areas of Guangdong Province. Tea enterprises (tea farmers) have 
high willingness to accept green weed management technologies, but the actual utilization rate is low. Therefore, it is necessary 
to further simplify the implementation difficulty of the existing green weed management technologies, formulate weed control 
regulations and strengthen the publicity and promotion of green weed management technologies.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The study was to explore the spatial structure of coordinated development of rural tourism in Shandong Province under the background of comprehensive tourism.【Method】Taking 539 rural tourism demonstration sites of 4 categories as research samples, the spatial distribution and influencing factors of rural tourism demonstration sites in Shandong Province were analyzed by using spatial econometric method.【Result】The spatial distribution characteristics showed that the average nearest-neighbor index of rural tourism demonstration sites in Shandong Province was 0.8129, indicating that the provincial-based rural tourism demonstration sites were significantly clustered, and the unbalanced index was 0.169, indicating that the spatial distribution of city-based rural tourism sites was imbalanced. The results of nuclear density analysis showed that inter-province area had the characteristics of multi-center pattern with Jinan, Taian, Weihai, Weifang and Binzhou as the cores, and the aggregation centers and distribution patterns of different types of rural tourism demonstration sites were different. The Moran’s I index was -0.4243, which showed that the spatial correlation pattern of the distribution of rural tourism demonstration sites was not obvious, and the differences between cold and hot spots were not significant. From the perspective of regional differences, the central region of Shandong presented a centralized contiguous distribution with the highest location entropy （1.14）. However, the development degree in northwestern Shandong was relatively lagging behind with the lowest location entropy （0.77） .The influencing factors of spacial distribution revealed the spatial distribution of rural tourism features such effects as reduction in number from downtown to suburb, promotion of traffic convenience, radiation of high-level scenic spots, resourcezation of natural geographical environment and correlation of social and economic development. 【Conclusion】Based on the results, some countermeasures and suggestions are proposed as follows: The all-round layout and coordinated 
development of provincial-based rural tourism sites facilitate to realize the effective integration of regional resources and coconstruction and sharing; Regional resource advantages at city-based rural tourism sites should be highlighted and cooperationcompetition development model be emphasized to achieve functional complementation and progressive promotion of different regions; The three-dimensional spatial system of “material-culture-society” in rural areas should be optimized to improve the functional layout of basic nodes.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The study was to quantitatively evaluate the effects of cultivated land protection policies in China from 1996 to 2017 through policy quantification, and to calculate the contribution rate of cultivated land protection policies. Then an evaluation of the effect of cultivated land protection policies in China was carried out to provide references for developing and strengthening cultivated land protection policy system.【Method】The policies related to cultivated land protection in 1996-2017 were quantified from three aspects of policy strength, policy objective, and policy measure, and the annual cultivated land protection policy intensity index during the study period was calculated, then a multiple linear regression analysis model was constructed on the combination of the cultivated land area and social and economic factors that related to cultivated land protection. On the basis of combing the development history of cultivated land protection policies in China, the effects of cultivated land protection policies from 1996 to 2017 was quantitatively analyzed according to the model.【Result】From 1996 to 2017, cultivated land protection policies in China had protected the equivalent of 1.59% of cultivated land in 2017, accounting for 24.47% of the total decrease in cultivated land area from 1996 to 2017; from 1996 to 2003, cultivated land protection policies in China had protected 18.14% of the total decrease in cultivated land area from 1996 to 2003; from 2003 to 2017, cultivated land protection policies in China had protected the equivalent of 0.70% of cultivated land in 2017, accounting for 44.37% of the total decrease in cultivated land area from 2003 to 2017. 【Conclusion】Cultivated land protection policies in China are effective, and they have played an important role in the cultivated land protection work for more than 20 years. It needs to be persisted for a long time. After a long period of accumulation and development, cultivated land quantity protection policy system in China has gradually been improved after 2003. In the future, while putting more effort to the quality and ecological protection of cultivated land, the protection of the quantity of cultivated land should continue to be maintained or strengthened.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The ecological carrying capacity of cultivated land in Qinghai Province was studied to provide decision-making basis for agricultural industrial structure adjustment, ecological security warning, regional economic development and overall land use planning.【Method】Taking the ecological carrying capacity of cultivated land in Qinghai Province in 2017 as the starting point of this study, the supply and demand balance index of ecological carrying capacity was analyzed through GIS spatial analysis and the ecological footprint model, then the current situation of supply and demand balance of cultivated land ecological footprint in Qinghai Province was evaluated, and its driving factors were analyzed. 【Result】（1）The ecological footprint of cultivated land in the eastern region of Qinghai Province is larger than that in the 
western region, and the calculated results are in good consistency with the total population of each city（state）;（2）The correlation ratio of ecological carrying capacity of cultivated land can not match perfectly in regional distribution, mainly due to the difference of total cultivated land area among various cities（states）;（3）In general, the ecological carrying capacity of cultivated land in each city of Qinghai Province belongs to the ecological surplus area and ecological balance area, and there is no ecological deficit area;（4）The spatial distribution of ecological carrying capacity of cultivated land in Qinghai Province is still unbalanced, the balance between supply and demand of ecological carrying capacity of cultivated land in the western region is better than that in the eastern region. Haibei, Hainan and Haidong in the northeast have been in the state of critical overload,and the critical overload area is in good consistency with the region with rapid economic development.【Conclusion】Special attention should be paid to the overall land planning in Qinghai Province, and the balance of ecological protection and economic development should be done well for the consideration of long-term development. In terms of cultivated land resources, we should stick to the principle to provide protection for the ecological sustainable development at the same time.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objectire】The study was conducted to clarify the influencing factors of farmers’ concurrent business on the adoption of production technology, and provide basis for the development of concurrent business farmers’ agricultural production and the promotion of new varieties and technologies. 【Method】From the perspective of concurrent business, the production behavior of 214 concurrent business farmers in Northeast China was investigated. Binary logistic model was used to analyze the influencing factors of concurrent business farmers adopting new technologies. 【Result】The results show that years of education have a significant effect on farmers’ planting willingness. According to the survey data, 58.9% of them have been educated for more than 9 years, which provides a better guarantee for the promotion of new things. The proportion of labor force has an extremely significant effect on farmers’ planting choice intention. The higher the proportion of migrant workers, the more the farmers’ own interests can be guaranteed, and the stronger the willingness to adopt new technologies. On the premise of ensuring family income, farmers are more willing to adopt new technologies to better safeguard their own interests. 【Conclusion】Based on the research results, in regard to how can farmers better adopt new technologies under the background of concurrent business, some countermeasures and suggestions are put forward, such as perfecting the land circulation system, strengthening the cultivation of new farmers and the introduction of talents, encouraging innovation, enhancing guidance and government participation.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Implementing the rural revitalization strategy is a major strategic deployment made at the 19th National Congress of the Communist Party of China. It is necessary to explore the development path of county-based rural revitalization strategy supported by science and technology of provincial agricultural research institutions, which is of great demonstration significance to solve the unbalanced development in urban and rural areas and the insufficiency of rural development in Guangdong. Taking the“Academy-County”cooperation between Guangdong Academy of Agricultural Sciences and Dongyuan County as an example, based on the local working platform of modern agriculture promotion center coconstructed by the Academy and the County, the cooperation was started from the system and mechanism to promote scientific and technological resources and talents to “enter into enterprises and villages” under the guidance of planning and by means of the service of the whole industrial chain. In this way, a scientific and technological cooperation model featuring government guidance, enterprise leadership and scientific and technological support was established gradually. Thanks to the scientific and technological cooperation of the Academy, local government and enterprises, the science and technology level of agricultural industry development in Dongyuan County has been improved constantly, with thriving new agricultural business entities and competitive featured brands. The rural science and technology commissioners have highlighted their roles, and preliminary successes have been achieved in the scientific and technological cooperation of government, enterprises and academy. All of these have created a sound ground for pushing the county-based rural revitalization strategy supported by science and technology. In view of the problems such as insufficient mobilization of various forces in the Academy and the County, shortage of complementary advantages in promotion forces of agricultural technology and lagging development of new agricultural business entities, some countermeasures and suggestions are proposed to further strengthen the organizational leadership of the government, form joint work force, strengthen the effect of platform to improve the promotion capacity of agricultural technology at primary level, deepen the cooperation of government, enterprises and academy, make leading enterprises more powerful and prominent ones, increase capital investment, and guide the accumulation of social resources.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In recent years, the development of urban agriculture in Guangzhou has achieved gratifying results, which plays an important basic role in the development of the whole city of Guangzhou, however, there are also many shortcomings, such as slow growth of urban agriculture, declining scale of agricultural industrialization, imbalanced urban and rural development, single channel for increasing farmers' income, weak ability of agricultural science and technology innovation, shortage of rural talent resources, lack of characteristic agricultural products, and lagging development of leisure agriculture. It is of great significance to strengthen the researches on innovation and development strategies of urban agriculture in Guangzhou under the conditions of the reduction of rural employees and cultivated land area to improve the quality and efficiency of agricultural development, increase farmers’income, and promote the coordinated development of urban and rural areas. This paper discusses the causes and disadvantages of short board from the perspective of meteorology, and proposes several countermeasures and suggestions from speeding up the construction of modern agricultural information system, giving full play to the benefits of modern agrometeorological services, paying attention to exploring agricultural production, transferring market risks, actively developing agricultural services for leisure tourism, and strengthening scientific and technological innovation cooperation of“agriculture + meteorology”according to the development trend of urban agriculture in Guangzhou. The research results show that although the increase of farmers' income can not directly rely on meteorological services, modern intelligent agrometeorological services play an important role in promoting the development of agricultural modernization, the integrated development of rural and urban areas, meteorological disaster prevention and mitigation. Government departments should strengthen the exploration of the application of“agriculture + meteorology”, give full play to the benefits of agrometeorological services and realize the equalization of meteorological public services.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Globally, 86% of coconuts are grown in southeast Asia. In China, 99% of coconuts are grown in Hainan province. In 2018, the output value of coconuts in Hainan reached 386 million yuan, with a total output of 226 million. The main varieties are "Wenye 2", "Wenye 3", "Wenye 4" and etc. The cultivation, varieties, prices, costs and benefits of coconut industry in Hainan in the past ten years were summarized, and the advantages, disadvantages, opportunities and challenges of coconut industry were analyzed. With favorable climate and soil as well as rich variety resources in Hainan, it is very suitable for coconut cultivation, however, there is imbalance in the processing and planting industries. There are several weaknesses including extensive management, slow industrial returns and low deep processing level of coconut products. Coconut industry is facing important historical opportunities of the construction of free trade zone and implementation of national rural revitalization strategy, as well as challenges of insufficient supply of coconut raw materials and low price competition of homogeneous products. Policy suggestions such as combining production, education and researches to form a new pattern of differentiated competition of coconut products were proposed.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=202005017&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The planting areas and the yields of vegetables rank first among various crops in Guangzhou. Vegetable cultivation has become one of the most important industries of urban modern agriculture in Guangzhou. However, the vegetable cultivation in Guangzhou is dominated by open-air production, which is prone to suffer from various meteorological disasters and cause huge losses. As an effective means to disperse and transfer agrometeorological disasters, agricultural insurance is an important measure to ensure the sustainable development of agriculture. Therefore, it is of strong practical significance to develop insurance products for vegetable cultivation. With precipitation and strong wind as meteorological indexes, the daily precipitation ≥ 100 mm, or daily maximum wind speed ≥ grade 7 are set as claim standard, and different insurance rates in various districts are determined to reduce the basis risk according to the difference of historical meteorological data in each district. The vegetable meteorological index insurance products that can be easily understood and accepted by farmers are constructed, the pilot extension of which has achieved good results in Guangzhou. The agricultural insurance varieties in Guangdong have been enriched, which effectively solve the outstanding problems of agricultural commercial insurance and policy insurance in Guangdong, and play a positive role in improving the ability of vegetable planting to resist risks and promoting the sustainable development of vegetable planting industry. It is suggested that government departments should increase the density of meteorological monitoring, develop meteorological index insurance products actively, strengthen cooperation in research and development of insurance products, strengthen the capacity building for disaster prevention and reduction in rural areas, increase the publicity of meteorological index insurance, summarize the experience of pilot work promptly, establish and improve the agricultural insurance security system based on policy-oriented agricultural insurance, construct multi-level risk dispersion mechanism of agricultural insurance, help to build a modern industrial system with Lingnan features and promote the development of modern agriculture and the revitalization of rural industries.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The study is to provide a scientific method for determining the insurance rate of cold damage to Chinese cabbage in the open field. It also has a reference to the determination of the insurance rate of other meteorological indexes, and provides assistance for the sustainable development of policyoriented agricultural insurance.【Method】The frost dates of the beginning and the end of each year（1957-2018）were converted into Julian days. Through calculation, the average frost dates of the beginning and the end of each year were obtained, which were set as the time thresholds for the cold damage index insurance, and the rationality of the threshold setting was tested by using the standard deviation classification method. The input costs of Chinese cabbage in various growth periods were counted accurately, and the compensation ratio was calculated according to the disaster damage rate. Through the calculation of occurrence probability, disaster damage rate and compensation ratio, the insurance rate of cold damage to Chinese cabbage in open field was obtained, and the weighted calculation for planting area was carried out to get the insurance rate of cold damage to Chinese cabbage in open field of planting area.【Result】The calculation method of the time and temperature thresholds for the freezing injury meteorological index insurance of Chinese cabbage in open field was designed, and the test method of the time threshold was established. The calculation method of three decisive factors of cold damage insurance rate -occurrence probability, disaster damage rate and compensation ratio was designed.【Conclusion】It is reasonable to set the average initial and final frost dates as the time thresholds for the cold damage meteorological index insurance of Chinese cabbage in the open field of Fengning Manchu Autonomous County. The damage rates of the Chinese cabbage in open field are 0.3, 0.7 and 1.0 when it suffers from the light, medium and heavy freezing injury. The highest compensation rate is 45% in the germination period, 75% in the seedling period and 100% after the rosette period. The insurance rate of the meteorological index of cold damage to Chinese cabbage in the open field of each town is 2%-3%, and the cold damage insurance rate in Fengning Manchu Autonomous County is 2.14% by weighted calculation.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】Technical efficiency is one of the important indicators reflecting the green development level of aquaculture, and assessing the efficiency of aquaculture technology plays an important role in promoting the optimal allocation of production factors in different provinces.【Method】The comprehensive technical efficiency of aquaculture in 31 provinces in China was evaluated and analyzed by using the DEA model based on the statistical data in 2018, the cluster analysis was carried out for 31 provinces by using the results of comprehensive technical efficiency, and the redundancy of input factors when the technical efficiency was effective was measured.【Results】It was found that comprehensive technical efficiency of aquaculture nationwide was overall low, with an average value of 0.827, and the average values of pure technical efficiency and scale efficiency were 0.93 and 0.89, and there was room for improvement in both pure technical efficiency and scale efficiency. The comprehensive levels of aquaculture input factors and technology applications were significantly different in different provinces, and the comprehensive technical efficiency of 11 provinces were effective, accounting for 35.48%, while the comprehensive technical efficiency value of 48.39% provinces was lower than the mean level. The variation characteristics of aquaculture returns to scale in different provinces were different, and the number of provinces with increasing returns to scale reached 18, accounting for 58.06%, which indicated that increasing the scale of input factors was a feasible way to improve efficiency. The three echelons divided by cluster analysis included the primary aquaculture producing provinces and non-primary producing provinces, which meant that the comprehensive technical efficiency was not directly related to output scale.【Conclusion】In order to promote the steady improvement of aquaculture efficiency, it is proposed to increase the scale of aquaculture, strengthen the technology innovation ability of aquaculture, arrange aquaculture input factors reasonably, and predict the demand for early-warning aquaculture production scale.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=202003017&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The study was to explore the correlation effect between cultivated land utilization intensity （CLUI）and comprehensive grain production capacity（CGPC）in Guangxi, and provide a reference for the implementation 
of the responsibility system for food security in Guangxi.【Method】The output, scale and comprehensive comparative 
advantage index were used to calculate the CGPC of Guangxi. Based on the evaluation index data of CLUI in Guangxi from 2010 
to 2017, the improved grey relational model was used to analyze the correlation effect between CLUI and CGPC.【Result】 
There was a significant correlation effect between CLUI and CGPC in Guangxi, but there were some differences due to different 
kinds of crops . The CGPC of rice was characterized by triangular arrowheads correlation pattern of “material intensity + 
planting intensity + technology intensity”, while the CGPC of corn was characterized by single correlation pattern of “planting 
intensity”, CGPC of soybean was characterized by double correlation pattern of “planting intensity + material intensity”, 
CGPC of potato was characterized by single correlation pattern of “labor intensity”.【Conclusion】Based on the correlation 
effect between CLUI and CGPC in Guangxi, it is suggested to improve the mechanism of cultivated land regulation and balance 
of land use and compensation to ensure the effective use and supply of cultivated land, to adjust the planting structure of crops 
and optimize the distribution of regional grain production, to strengthen agricultural technology research and development and 
promotion and make full use of intercropping pattern, to optimize the mechanism of allocation of rural labor for realizing land 
conservation and grain production and income increase through multiple channels.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】By analyzing the impacts of Sino-U.S. trade frictions on Guangdong Province’s aquatic 
product trade to the United States, relevant countermeasures and suggestions were put forward to mitigate the negative 
impacts of Sino-U.S. trade frictions and promote the transformation and upgrading of aquatic product enterprises in 
Guangdong. 【Method】Combined with the statistical data and semi-structured field survey, this paper used TC index 
method to analyze the current situation of Guangdong Province’s aquatic product trade to the United States, and discussed 
the impact on the market of Guangdong Province’s aquatic product to the United States under the background of Sino-U.
S. trade frictions from macro to micro, and put forward countermeasures and suggestions from the perspectives of enterprises, 
industries and governments.【Result】After the Sino-U.S. trade frictions in 2018, export trade of aquatic products of 
Guangdong Province faced greater uncertainty. From a macro perspective, it led to the decline of competitiveness of aquatic 
products, the trade surplus turned into trade deficit, the export of aquatic products to the United States was blocked, the proportion of domestic sales increased, and some aquatic products exported to the United States turned to be sold to the ASEAN 
and Australian markets; from a micro perspective, it had a negative impact on the upstream, midstream and downstream links 
of aquatic products, for example, the non-US and domestic markets was widened, the processing volume was reduced, and the 
breeding plan was not clear.【Conclusion】Guangdong aquatic products enterprises should take into account the domestic 
and foreign markets to stimulate consumption potential, lead the farmers to change the breeding mode to improve their anti risk ability, strengthen scientific research and enhance the core competitiveness fundamentally. Trade associations should play 
a leading role in jointly preventing risks. It is also suggested that the government should introduce relevant supporting policies 
and cooperate with enterprises to deal with Sino-U.S. trade frictions in a more leisurely manner.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[To solve the common problems of idle resources and weak economy in traditional agricultural villages, clarify 
the reform path of “Three Changes”, gather resources and capital assets, guide the reform of traditional land management 
mode, and provide references for the sustainable development of “Three Changes”reform and rural revitalization, this 
paper analyzes the “Three Changes”reform and development path of the traditional agricultural village, constructs the 
comprehensive benefit evaluation index system of the “Three Changes”reform, and uses the entropy weight AHP fuzzy 
comprehensive analysis method to quantitatively evaluate the comprehensive benefit changes of Fude Village of Chongqing 
City before and after the “Three Changes”reform. In 2018, the comprehensive benefit index of “Three Changes”reform 
in Fude Village was 0.758, which was in a “good”position, with stable growth of rural economy; its social and economic 
benefits improved significantly. Compared with 2015, its village score, economic benefit score, ecological and environmental 
benefit score and overall benefit score increased by 0.498, 0.388, 0.216 and 0.395, respectively. The “Three Changes”reform 
and development momentum is clear. The reform of “Three Changes”in social benefits has solved the problems of scattered differentiation of traditional agricultural industries and low operating benefits, and improved the comprehensive development 
benefits of rural areas. However, it is faced with many problems, such as the difficulty of controlling agricultural operation risks, the 
single and chaotic landscape diversity, the relative stagnation of construction land shareholding, and the instability of cooperative 
equity. On this basis, in order to ensure the sustainable development of the “Three Changes”reform and improve the relevant 
reform path, relevant countermeasures and suggestions are proposed.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The rural farmland property right system is one of the basic systems in the countryside. The experience 
in the changes of the farmland property rights system since the founding of new China has important historical value and 
research value. By using the analysis paradigm of gradual institutional change theory of historical institutionalism, the 
farmland property right system change mode of new China is identified. From feudal land ownership system to farmer land 
ownership through system replacement mode, from farmer ownership system to farmer collective ownership through system 
conversion and replacement mode, from farmer collective ownership system to "separation of two rights" property right system through system layering mode, from the "separation of two rights" property right system to the "separation of three 
rights" property right system through system drift mode, it indicates that the change of farmland property right system in New 
China is gradual and highly path-dependent. The change of farmland property right system is the result of multiple causes and 
effects. In the future, the reform of farmland property right system should be carried out from multiple perspectives: optimizing 
the structure of farmland property right with the reform of collective property right system, reshaping the values of rural land 
with the strategy of rural revitalization, stimulating the reform and upgrading of farmland property right system with the help of 
agricultural digitalization, and promoting the well-ordered transformation of farmland property right system.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=202002019&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】Antimicrobial resistance surveillance is a vital task in the field of public health safety. Up 
to now, most results of antimicrobial susceptibility testing (AST) need to be recognized manually, which lead to subjective 
interpretations of experimental results and lower working efficiency. In this paper, an automatic method for interpreting AST 
results of microporous image recognition based on convolutional neural network is proposed.【Method】According to the 
data set of MIC test image construction provided by the National Veterinary Micromicrobial Resistance Risk Assessment 
Laboratory, the image recognition model of single microporous AST result was trained by, using two convolutional network 
models - Inception_V4 and MobileNet_V1. Based on the classification results of the model recognition, the MIC value 
calculation method and the drug resistance recognition method were established, and the automatic identification of the AST 
results was achieved.【Result】With the two Convolutional Neural Networks - Inception_V4 and MobileNet_V1Inception_
V4, the accuracy rates of image recognition of single microporous AST results were 99.99% and 99.97%, respectively.And the accuracy of MIC value and drug resistance recognition reached 97.30%, 94.40% and 99.13%, 98.40%, respectively. 
【Conclusion】Both of the two convolutional neural networks can replace manual interpretation, to improve the work efficiency 
and reduce the professional requirements for experimenters. Compared with Inception_V4, the interpretation accuracy of the 
MobileNet_V1 model is slightly lower, but the efficiency is higher, and the practicality can be reached.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In order to realize the effective protection of giant panda species, China has been promoting the system of 
establishing giant panda national parks. Reserves are the core areas of these giant panda national parks, and the health and 
stability of their forest ecosystems are the top priorities for the conservation of panda species, for which the value of forest 
ecological services directly reflects the conservation effectiveness of the giant panda national parks. Since the 1990s, scholars at 
home and abroad have carried out many researches on the forest ecological service functions, while researches on the“panda 
reserve”as a specific subject are still insufficient, especially the selection of measurement system and method for evaluating 
the specific forest ecosystem service functions in giant panda reserve needing to be further discussed. Based on this, this paper 
summarizes the development process of framework for the evaluation of ecological service value and the evaluation indicators of 
forest ecological service functions in the giant panda reserve, introduces the application of evaluation method in this field, and 
finally discusses the shortcomings in the current research and the possible improvement direction in the future.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The research is to analyze the risk of the impact of super typhoon“Mangkhut”on the agriculture of Yangjiang City. Specifically, the important factors of typhoon disasters influencing the agriculture were quantitatively identified to provide references for the prevention of typhoon disasters and the work of post-disaster reconstruction.【Method】With the support of GIS, the natural disaster risk index and the weighted comprehensive evaluation method are used to establish a comprehensive risk assessment model for the impact of typhoon on agricultural production to carry out typhoon risk zoning. The model covers sensitivity, exposure and disaster resistance. In addition, the important driving factors of the impact of typhoon disasters on regional agriculture were quantitatively identified based on the geographic detector method.【Result】The areas of the highest agricultural risk area, higher risk area and medium risk area of typhoon disaster in Yangjiang City account for 0.52%, 0.06%, and 13.5% of the area of agricultural production in the study area, respectively. Totally, the areas of lower risk area and the lowest risk area account for 85.87% of the area of agricultural production. The q value of the influence of the three driving factors of sensitivity, exposure, and disaster resistance on the disaster risk index is 0.12, 0.04, and 0.07, respectively. The q value of the combined effect of sensitivity factor and disaster resilience factor on disaster risk index is 0.24.【Conclusion】The typhoon disaster risk level decreases gradually from the coast to the inland, and is closely related to the terrain. The risk index of flat cropping and fishing areas along the coast and hinterland is high and that of the northern forests is relatively lower. The sensitivity has the greatest influence on the risk index, followed by disaster and exposure. There are significant differences in the degree of influence and spatial characteristics of different driving factors on the risk index, and the combination of every two driving factors will increase the risk index.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In recent years, with the development of technology and artificial intelligence, the improvement of 
agricultural unmanned aerial vehicle（UAV）technology has become more and more perfect, the usage of agricultural 
UAV is increasing, and it has been increasingly applied to crops widely. Rice is the second largest food crop in China, 
and agricultural UAV have been widely used in the field of rice production. Agricultural UAV are mainly used in plant 
protection, aerial sowing and hybrid seed production. Compared with the traditional manual operation, the agricultural 
UAV for low-altitude operation has high efficiency, low labor intensity and uniform operation quality. It is much cheaper 
than manned large aircraft operation and can meet the needs of developing an efficient agricultural economy. In particular, 
China has developed a variety of suitable UAV for situations where ground machinery is difficult to operate in rice field. 
In this paper, the development status and the classification of the main types of agricultural UAV in both domestic and 
overseas related researches were summarized. The application status of agricultural UAV in rice plant protection, aerial 
sowing, hybrid seed production and other aspects in China, and the problems existing in the application of agricultural 
UAV in rice production were emphatically introduced. It was also proposed some suggestions to improve relevant laws, regulations and system standards, strengthen the research and development of UAV batteries and strengthen the research 
of special agents and additives with a view to provide references for further promoting the whole process mechanization and 
agricultural modernization of rice production in China.]]></description>

measure the market efficiency of collective construction land from 1995 to 2001 and 2012 to 2018. Then, the Differencein-Differences（DID）model was used to analyze the performance differences in the collective operational construction 
land market entry before and after the implementation of the pilot policy in Nanhai of Foshan City.【Result】After the 
implementation of the pilot policy of collective operational construction land in 2015, the utilization efficiency of collective operational construction land in 2017 was 0.78% higher than that in 2015, indicating that the pilot reform of collective 
operational construction land market entry promoted the improvement of the expectation of rural collective operational 
construction land entering the market. The incomes of rural residents had a positive impact on the utilization efficiency of 
collective operational construction land, which were significant at 5% level. The total agricultural output value and cultivated 
land area had negative impacts on the utilization efficiency of collective construction land, which were significant at levels of 
5% and 1%, respectively.【Conclusion】Policy pilot areas should be combined with the local actual situation to explore new 
ways and methods; We should“break through”the barriers of reform pilot and enhance the cooperation of reform pilot.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[As China’ s economy enters the new normal, the economic growth mechanism of traditional forestry 
industry has little effect. If forestry industry wants to achieve high-quality development, which increases the gross output 
value of forestry industry and promotes the optimization and upgrading of forestry industrial structure, it must rely on the 
human capital. Based on the forestry panel data of 31 provinces in China from 2000-2018, it empirically tested the impact 
of human capital on the development quality of forestry industry, and explored the mediating role of technological progress 
and the moderating role of physical capital input. The results show that human capital significantly positively affects the 
development quality of forestry industry. Among them, compared with the coefficient of human capital on the total output 
value of forestry industry, its influence on the upgrading of forestry industrial structure is slightly weaker, indicating that in the rationalization and upgrading of forestry industrial structure, compared with the huge number of forestry labor force, the real 
high level of human capital is insufficient. Technological progress has a significant intermediary effect between human capital 
and the development quality of forestry industry. It shows that forestry talents can absorb and imitate advanced production 
technology, promote the replacement of modern production factors to traditional production factors, improve the production 
efficiency of forestry, and realize the high-quality development of forestry industry by virtue of their own endowment ability 
and knowledge level. Insufficient investment of physical capital weakens the influence of human capital on the development 
quality of forestry industry. It indicates that the development of the forestry industry needs a lot of financial support, and not only 
relying on government investment which can not effectively support the transformation of the forestry industry, but also need to 
introduce private capital. Based on this, it is suggested to enhance the construction of forestry talents, to improve their treatment, 
and take the road of promoting forestry through science and education and strengthening forestry with talents, to actively absorb 
the management experience and advanced technology of developed countries and enhance the content of forestry science and 
technology, to introduce private capital investment and inject capital and vitality into the development of forestry industry.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=202107020&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】In recent years, with the gradual implementation of important agricultural product security 
strategies, the Party and the State attach great importance to the development of natural rubber industry. The supply and 
demand situation and price trend of natural rubber and other strategic agricultural products are paid more and more attention 
from all sectors of society. Especially, since the outbreak of Novel Coronavirus Pneumonia, it is of great importance to build 
a new development paradigm featuring dual circulation, in which domestic and international markets reinforce each other. 
Natural rubber is an important strategic material in China and futures markets are maturing, therefore, it is imperative to 
study the relationship between domestic and foreign price fluctuations of natural rubber.【Method】With the statistics data 
of the natural rubber at home and abroad since 2010 from Ministry of Commerce, the unit root test and Granger test, impulse 
response model, analysis of variance model are used to analyze fluctuation rule and inner link of the natural rubber futures 
and spot prices at home and abroad, and the future trend of supply and demand for natural rubber is forecast.【Result】It is 
found that the domestic futures price of natural rubber affects both the domestic spot price and the change of the international 
futures price. The increase of the domestic futures price will have a positive impact on the foreign futures price and domestic 
spot price, but the influence of the international futures price is nearly 10 times than that of the domestic futures price. The discovery effect of domestic futures price is stronger and the radiation force of price is stronger and stronger.【Conclusion】
Based on the relationship between the futures and spot price fluctuations in natural rubber at home and abroad, some policy 
suggestions are put forward to improve the competitiveness of natural rubber industry, such as the precise support policy for 
optimizing natural rubber production reserves, monitoring and early warning of natural rubber market and strengthening of each 
link of natural rubber industry chain.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Forests are the largest carbon reservoirs in terrestrial ecosystems, which absorb carbon dioxide, produce 
oxygen, conserve water, preserve soil and water, regulate climate and other functions, and play a very important role in 
reducing the concentration of greenhouse gases in the atmosphere and mitigating global warming. Data from the Ninth Forest 
Resources Inventory showed that China’ s forest area was 220 million hm2
, with a stock volume of 17.56 billion m3
, and the 
forest coverage rate was 22.96%. Compared with the data from the Eighth Forest Resources Inventory, the forest coverage 
rate increased by 1.33 percentage points, which correspondingly increased the carbon sink capacity of trees. At the NPC 
and CPPCC sessions in 2021, “carbon peak” and “carbon neutrality” were written in the government work report for the 
first time and included in the overall layout of ecological civilization construction, which attracted much attention. In other 
words, China’ s carbon dioxide emissions must reach a peak before 2030, after which its net emissions must be gradually 
reduced, striving to achieve carbon neutrality by 2060. In order to further achieve the goal, China will start the construction 
of a national carbon emission trading market in 2021, and gradually expand its coverage of the industries, enriching the types and methods of trading. Forestry carbon sink trading based on market mechanisms has become an important means to 
achieve “carbon peak” and “carbon neutrality”. According to the actual transaction, compared with the forestry carbon sink 
project under China Certified Emission Reduction（CCER）mechanism, the forestry generalized carbon trading in Guangdong 
Province has developed rapidly. Therefore, this paper compares the methodology of the CCER mechanism with the PHCER 
mechanism in Guangdong Province to analyze the reasons for the rapid development of the forestry generalized carbon trading 
in Guangdong Province. The results show that it has greatly reduced the transaction risks and costs of forestry carbon sink in 
terms of participant restrictions, baseline setting and crediting period selection, thus promoted its development. Finally, relevant 
policy suggestions are put forward accordingly.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Chemical fertilizer reduction is the key to control non-point source pollution and promote rural ecological revitalization and agricultural sustainable development. It is found from the literature at home and abroad that phenomenon of excessive fertilizer application in China is common and reduction potential is large. As the main users of chemical fertilizers and participants in environmental pollution prevention and control, farmers are lack of awareness of this phenomenon, which increases the risk of environmental pollution. Furthermore, factors influencing the willingness and behavior of farmers to reduce fertilizer use include farmland characteristics (such as farmland resource endowment, farmland circulation and management), social-economic environment (such as machinery use, technical training), individual family characteristics, farmers’ cognitive level and risk attitudes, etc. With the gradual improvement of agricultural land transfer market in China, emergence of new agricultural business entities such as family farms, new technologies such as soil testing and formula fertilization as well as organic fertilizer substitution for chemical fertilizer, dynamic changes of farmers’ behavior and willingness can be further explored from the perspective of time vertical or regional horizontal so as to guide farmers to reduce fertilizer input and realize sustainable development of agriculture.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The study was carried out to improve the technical efficiency of chemical fertilizer application in litchi production, reduce the production cost and improve the incomes of litchi growers and the development of litchi industry.【Method】The industry economic station team of litchi and longan industry technology system was arranged to conduct field survey on litchi growers one-on-one in Guangdong, Guangxi and Hainan Provinces from August to September 2016, construct stochastic frontier production function model to estimate the chemical fertilization technical efficiency in litchi production, and use multiple regression function model to analyze the influencing factors of chemical fertilization technical efficiency.【Result】The average technical efficiency of chemical fertilizer application for litchi growers was 0.419 in the survey areas. Compared with the optimal 100%, the chemical fertilizer utilization rate in litchi production was low. The highest technical efficiency of chemical fertilizer application for litchi growers was 0.551 in Haikou Comprehensive Test Station of Hainan Province, and the lowest was 0.332 in Yulin Comprehensive Test Station of Guangxi 
Province. The highest litchi chemical fertilization technology efficiency demonstration county was Changjiang County in Hainan（0.690）and the lowest demonstration county was Xinyi in Guangdong（0.104）. Household per capita income had a significant positive effect on litchi chemical fertilization technical efficiency, while average fixed assets, fertilizer amount（net volume）, household labor force ratio and cultivated area had a significant negative effect on litchi chemical fertilization technical efficiency.【Conclusion】It is suggested to formulate a reasonable scheme for guiding litchi growers to correctly understand the technical efficiency of chemical fertilizer application, and practically promote technical training to improve the technical efficiency of chemical fertilizer application.]]></description>

object, a visual analysis was conducted with citespace software by bibliometric method, and the research status, hot spots and 
trends of intelligent agriculture at home and abroad were sorted out and summarized. A comparative analysis was conducted 
through the researches at home and abroad and relevant countermeasures and suggestions were put forward. The research 
found that:（1）At present, the number of publications of domestic researches on intelligent agriculture is increasing. 
Domestic and foreign scholars have continued to increase researches on intelligent agriculture, however, there is little 
cooperation between domestic and foreign scholars in the field of intelligent agriculture. There is less cooperation among 
domestic institutions with higher levels of scientific research on intelligent agriculture, and there is a lack of uniformity in the 
definition of intelligent agriculture in academia.（2）There are certain differences in the priority of intelligent agriculture 
researches at home and abroad, and foreign researches focus on the integration of various disciplines and pay more attention 
to the role of intelligent agriculture in coping with climate changes and the construction of intelligent agriculture systems; 
while domestic researches mostly focus on the application and promotion of intelligent agriculture from a policy perspective, with certain policy inclination.（3）Quantitative research and interdisciplinary research will become the research direction 
of intelligent agriculture in the future. More extensive cooperation between domestic and foreign scholars and institutions 
in the field of intelligent agriculture is the general trend of intelligent agriculture research. The in-depth integration of new 
technologies represented by 5G will become the research hot spot of intelligent agriculture in the future. Based on this, from the 
perspective of giving play to the advantages of interdisciplinary and deep integration with new technologies as well as promoting 
the development of cooperation at home and abroad, corresponding suggestions are put forward.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In recent years, Guangdong Province has vigorously implemented the strategy of rural revitalization to 
accelerate the promotion of its agricultural modernization in the forefront of China, and the provincial agricultural research 
institutions in Guangdong have continuously developed new varieties, new technologies, new equipment and new models 
to expedite this process. How to promote the provincial agricultural scientific and technological achievements to the 
grassroots, in order to serve the market of agricultural products, to expand the promotion depth of agricultural scientific 
and technological achievements and improve the transformation efficiency of scientific and technological achievements has 
become the key to solve the dilemma of agricultural modernization in Guangdong Province. Huizhou Municipality innovated 
the way of agricultural promotion, cooperated with provincial agricultural research institutions and established Huizhou Modern Agricultural Promotion Center, which effectively promoted the development of agricultural modernization in Huizhou. 
Taking Huizhou Municipality as an example, this paper summarizes the problems existing in the development of agricultural 
industry, innovation and service of agricultural science and technology, extension of agricultural science and technology and 
transformation of achievements in Huizhou, and then focuses on the analysis of a series of innovative efforts made by Huizhou 
Modern Agricultural Promotion Center in helping to solve the problems of weak foundation of agricultural industry development, 
shortage of agricultural science and technology talents, and the “prisoner's dilemma” of academy-locality cooperation. In order 
to tackle with these problems, we have refined such grassroots promotion work modes as housekeeper-like and hematopoietic 
type of science and enterprise connectivity, serving temporary posts in branch institutes and bridging of scientific research 
project cooperation, implementing field-based training and guidance of agricultural technologies, and full coverage of the 
grassroots work stations “Academy-City-County-Town-Village” in all levels of administrative divisions. Finally, some 
suggestions for breaking the dilemma of local agricultural development and improving agricultural science and technology 
promotion were proposed.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Rice is one of the most important food crops in China. More than 60% of the population in the whole country feed on rice as the staple food. Guangdong Province is one of the 13 main grain producing areas in China. In recent years, the total rice output accounted for more than 76% of the total grain output. Meizhou City, as the third largest grain producing area in Guangdong Province, in which the efficient development of rice industry is of great significance to increase the selfsufficiency rate of grain in Guangdong. Thanks to the unique climate and ecological environment in the Meizhou area, Hakka 
rice grains are slender and crystal clear, and the rice is shiny and moist with soft and flexible taste, which is very suitable for the southerners. Meizhou “Hakka rice” was officially approved as a geographical indication of agricultural products by the Ministry of Agriculture in 2017. In the process of promoting the prosperity of the rural industry, Meizhou promoted the quality and efficiency of the agricultural industry by creating Hakka rice brands. Based on this, an in-depth analysis on Hakka rice of Meizhou City was conducted by consulting the statistical yearbook data of China, Guangdong and Meizhou and the historical rice planting data from the Meizhou Seed Supervision and Management Station over the years, and combining the rice production survey data of main implementation units led by four Simiao rice industrial parks. In-depth analysis on the development status of the Hakka rice industry in Meizhou was conducted and corresponding countermeasures and suggestions for the problems in the development of the industry were proposed in order to provide references and basis for the further development of the Hakka rice industry and government decision-making in Meizhou.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The study was conducted to improve the prediction accuracy of water temperature in prawn 
culture and grasp the change rules of aquaculture timely【Method】An prediction model of aquaculture water temperature 
based on Wavelet Threshold Denoising（WTD） and Long Short-term Memory（LSTM）neural network was proposed. The WTD method was used to eliminate the correlation between the original variables, reduce noise interference and enhance 
the smoothness of signal data. Furtherly, the LSTM with strong predictive power was used to predict the signals.【Result】
The mean absolute error（MAPE）, root mean square error（RMSE）, and absolute error（MAE）of WTD-LSTM were 0.0104, 
0.0382 and 0.0288, respectively. Compared with standard BP neural network, standard ELM and standard LSTM, the evaluation 
indicators of MAPE, RMSE and MAE decreased by 64.85%, 59.62%, 64.62%; 63.64%, 61.18%, 60.12%; and 47.48%, 37.07%, 
46.27%, respectively. According to the visual analysis, compared with the other three models, the prediction result of WTDLSTM was close to the true curve value, which could well fit for the nonlinear time series trend of aquaculture water temperature.
【Conclusion】The model has good prediction performance and generalization ability, which can meet the actual demand for 
accurate prediction of water temperature in prawn culture and provide decision-making for water quality prediction and early 
warning of prawn culture.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The study was carried out to analyze the current situation and problems of financial support 
for agriculture, evaluate the efficiency of financial support for agriculture in Guangdong Province, and provide policy 
recommendations for Guangdong Province to improve the efficiency of the use of financial support for agriculture and the 
high-quality development of agriculture.【Method】The three-stage DEA model was used to measure the efficiency of 
financial support for agriculture in Guangdong Province from 2000 to 2018 and that of 20 cities from 2010 to 2018.【Result】
The overall efficiency of financial support for agriculture in Guangdong Province showed a downward trend. The pure 
technical efficiency was relatively high, but the low scale efficiency led to low overall efficiency. Most cities were in a state of 
diminishing returns to scale. After the removal of three environmental factors including the regional GDP, damaged area of crops and number of agricultural technology associations and random interference items, the efficiency of financial support for 
agriculture in each city has changed to a certain extent. The overall efficiency of 11 cities has increased, the overall efficiency 
of 7 cities has decreased, and that of the provincial level has increased. Twenty cities were divided into four types of regions 
based on pure technical efficiency and scale efficiency of 0.9, and each type of region should be improved according to different 
situations. From the administrative area, the overall efficiency and scale efficiency of the Pearl River Delta region were low, 
while the pure technology efficiency in northern Guangdong was low, and the gap between the three efficiency values in the four 
regions was constantly shrinking.【Conclusion】Based on the research results, corresponding countermeasures and suggestions 
are proposed, including scientifically and rationally allocating financial support for agriculture, gradually establishing a modern 
system of financial support for agriculture; attaching importance to the impacts of external conditions on efficiency, creating a 
good environment for financial support for agriculture and actively guiding the continuous development of green agriculture to 
promote the implementation of relevant supporting policies.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[As bio-agriculture has become a new economic growth point, Guangzhou takes bio-agriculture as one of the important contents to improve the capacity of agricultural scientific and technological innovation during the 14th FiveYear Plan period. This paper aims to objectively show the scientific and technological innovation progress and industrial development in the field of bio-agriculture in Guangzhou at present, and explore the key points, strategies and measures for the innovation and development of bio-agriculture in the future. On the basis of combing the literature, this paper uses the analysis methods of comparison, statistics and clustering to explore the development policy, scientific and technological innovation, industrial development, existing problems and promoting strategies in the field of bio-agriculture in Guangzhou. The research shows that Guangzhou has made important progress in scientific and technological innovation in the fields of biobreeding, bioveterinary drugs and biopesticides. Biobreeding and biofeed have become the leading industries of bio-agriculture, and high-tech enterprises of bio-agriculture have risen rapidly. However, there are still some problems,such as the general small scale of enterprises, the low degree of transformation of R & D achievements, the weak capacity of independent innovation, insufficient support and so on. Under the background of paying close attention to the development of biological agriculture, Guangzhou should focus on the pain points and difficulties of the development of bio-agriculture, improve the whole-process innovation ecological chain of bio-agriculture, build a bio-agricultural science and technology innovation system, promote the innovation and agglomeration development of bio-agriculture, increase policy support, optimize the industrial development environment and improve the working mechanism and other measures to promote the innovative development of bio-agriculture in Guangzhou.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=202208017&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The diurnal variation, daily average evapotranspiration and cumulative evapotranspiration of 
late rice were analyzed. Based on the characteristics of evapotranspiration under typical weather conditions, the practical 
applicability of the new paddy evapotranspiration instrument was discussed.【Method】With the double-cropping late 
rice as research object, based on the water balance method, the evapotranspiration of late rice in 2017-2019 was measured 
by using a new type of ultrasonic evapotranspiration instrument.【Result】The actual data collection rate and effective 
data acquisition rate of the new ultrasonic evapotranspiration instrument are above 93%, and the measurement accuracy can reach 0.2 mm, which can ensure the availability of field observation data in terms of data stability. Based on the analysis 
of the evapotranspiration of double-cropping late rice on different time scales, it is found that the evapotranspiration of late 
rice in the whole growth period is about 466 mm, among which the accumulated evapotranspiration in the tillering stage is the 
highest, about 135 mm, and the average evapotranspiration in the jointing-heading stage of late rice is the highest, which is 
5.4 mm/d, indicating that late rice requires the most water at the tillering and jointing-heading stages. Under typical weather 
conditions (except rainy days), the diurnal variation of late rice evapotranspiration is in a “Ω” type, and the peak value 
of the evapotranspiration curve on sunny days is the largest, which is 1.3 mm/h. According to the fitted R2
 and p values, 
the evapotranspiration on sunny day, partly cloudy day and cloudy day conditions is distributed as a sixth-order curve.
【Conclusion】The research on the eigenvalues of rice evapotranspiration measured by the new type of evapotranspiration 
instrument and its applicability can provide an important reference for promoting the use of low-cost, high-precision and 
convenient new type of rice field evapotranspiration measuring instrument.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】Litchi, as an evergreen fruit tree, has become a landscaping tree due to lack of management. 
It is of great significance to the spatial layout optimization and standardized management of litchi industry by accurately 
understanding and mastering the spatial distribution and spatial variation trend of litchi planting areas.【Method】Taking 
the litchi planting areas in Zengcheng District of Guangzhou City as an example, the remote sensing technology was used 
to visually interpret the remote sensing images of 2015 and 2019, and the spatial variation characteristics of managed and 
unmanaged litchi planting areas were judged.The gravity center migration model and fragmentation index were used to quantitatively analyze the temporal and spatial variations of litchi planting areas.【Result】The overall accuracy of remote 
sensing interpretation is high, reaching 86.54 %. The planting areas of litchi in Zengcheng District are decreased by 67.69 
hm2
, in which the planting areas of litchi with management are decreased by 127.28 hm2
 and the planting areas of litchi without 
management are increased by 59.59 hm2
. Totally, the center of gravity of litchi planting areas gradually moves away from 
the town center, moving 45.14 m eastward and 107.01 m northward. Among them, the litchi planting areas with management 
move northwestward, and the litchi planting areas without management move southwestward. The fragmentation index of litchi 
planting areas increases from 0.0407 in 2015 to 0.0413 in 2019, and the spatial distribution shows a gradually dispersed 
pattern. However, the fragmentation index of litchi planting areas with management decreases from 0.0244 to 0.0238, showing 
a state of aggregation in space.【Conclusion】By using remote sensing technology, it can accurately and quickly identify the 
spatial distribution and variation characteristics of litchi planting areas under different management modes, provide accurate 
data support for inefficient orchard transformation and standardized orchard construction, and promote the prosperity of rural 
industries.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】With the continuous development of the information age, science and technology has 
become the fundamental driving force for the development of rural industries. In order to further activate the vitality of 
rural development and promote the integration of three industries in rural areas, it has become a strong support for rural 
revitalization.【Method】Based on the vector auto regression (VAR) model and relevant data of science and technology 
and industry in China from 2011 to 2019, the study explores the relationship between the integration of three industries in 
rural areas and the input of scientific and technological innovation through nine secondary indicators under three first-level 
indicators corresponding to the output of science and technology, the input of science and technology, and the integration 
of three industries in rural areas.【Result】Empirical analysis results show that, there is still a lot of room for continuous 
improvement in the degree of integration of three industries in rural areas. There are dynamic interactions and high correlations among the input intensity of science and technology, the output level of science and technology and the integration of 
three industries in rural areas in the index systems; the input of science and technology innovation can promote the development 
of integration of three industries in rural areas, which will increase 0.767% when the output of science and technology is 
increased by 1% in the current period; the development of integration of three industries in rural areas will promote further 
investment in science and technology innovation. When the comprehensive score of integration of three industries in rural areas 
increases by 0.881%, the comprehensive score of science and technology output increases by 1%.【Conclusion】Based on 
the above conclusions, we should focus on promoting agricultural scientific and technological innovation to overcome technical 
barriers, support and encourage agricultural scientific research workers to develop products and technological innovation, build 
a platform for scientific and technological innovation alliances, increase investment in scientific and technological research and 
development, create an environment for scientific research and innovation, and accelerate the pace of agricultural technological 
innovation in our country to realize the deep integration between traditional agriculture and high-tech industries.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[By means of literature review and field investigation in the sea area, the development and current situation 
of marine ranching at home and abroad are summarized, and the construction process of artificial fish reefs, proliferation and 
releasing and national marine ranching demonstration areas in Guangdong as well as the development status and existing 
problems of marine ranching related industries are analyzed. Guangdong has built 50 ecological artificial reef areas, 3 largescale artificial reef demonstration areas, 1 local artificial reef area and 15 national marine ranching areas, with a total sea 
area of 1 499.68 km2
, and 2.004 million m3
 of reefs being built. However, at present, there are some problems in Guangdong 
marine ranching, such as imperfect management mechanism, inconsistence in development concept and understanding, 
unclear rights and responsibilities in using sea area, lack of construction technology standards and specifications, low scientific and technological level and limited industrial development. Based on these problems, countermeasures for the 
development of marine ranching in Guangdong Province are put forward: insisting on ecology-prioritized development, and 
strengthening the coordination of multiple departments; creating a management mode conducive to market-oriented operation; 
break through the issue of sea area ownership; establishing a technical standard system for marine ranch construction in 
Guangdong; increasing the research on the basis of high-quality construction and key common technologies of Guangdong 
marine ranching; establishing industrialization modes of Guangdong m arine ranching according to local conditions. 
Understanding the development status of marine ranching in Guangdong and exploring the development strategies of 
marine ranching industry by referring to the relevant experience at home and abroad can provide references for the effective 
management, efficient and sustainable development of marine ranching in Guangdong and the integration of three industries in 
the development of marine ranching in Guangdong.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】In order to clarify the evolution mechanism of member heterogeneity, cooperative game 
and surplus distribution mode of farmers’professional cooperatives in China, cooperatives are divided into four stages: 
start-up period, growth period, maturity period and recession period based on the perspective of life cycle. It also makes a 
theoretical and empirical analysis on how the changes in the status of“capital”and“labor”affect the allocation of surplus claims of cooperatives.【Method】With game theory as a tool, the evolution of surplus distribution system at different stages of 
cooperative life cycle under the condition of heterogeneity is discussed. The typical case of Tiefo Navel Orange Planting Stock 
Cooperative in Fengjie County of Chongqing is used for empirical analysis.【Result】The evolution mechanism of the surplus 
distribution mechanism of farmers’cooperatives in China is clarified. The way of surplus distribution of cooperatives changes in 
the same direction as the power of cooperative game. When the cooperative is dominated by the“big farmers”of the investors, 
the cooperative tends to distribute the surplus mainly by shares. On the contrary, it tends to be distributed according to labor 
input (i.e. trading volume) in favor of“small farmers”.【Conclusion】At different stages of the life cycle of cooperatives, with 
the change of cooperative business objectives, the status of“capital”and“labor”will change accordingly. This has led to the 
evolution of surplus distribution. In terms of policy enlightenment, it also shows that inclusiveness, balance and synergy based 
on the perspective of life cycle support the incentive and compatible development of cooperatives. It can not only better bridge 
the uncertainty caused by the alienation of cooperatives, but also provide valuable ideas and exploration for the high-quality 
development of rural cooperative economic organizations in the new era.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Eel is a kind of high-quality edible fish with high protein and fat, and it is an important export agricultural 
product of Guangdong Province. With the upgrading of consumption, domestic consumers are increasingly interested in this 
nutritious aquatic product. Through the analysis of fishery statistics and field investigation, the development characteristics 
of the four main eel production areas in China were found out. The eel industry in Fujian Province had the highest cluster 
degree with strong competitiveness. Jiangsu Province has gained an important industrial status because of its unique eel fry 
resources. Jiangxi obtained the late-development advantage of eel industry by virtue of favorable geographical conditions. 
Guangdong eel industrial cluster has excellent breeding conditions and construction conditions of the whole industrial 
chain, and eel output ranks first. The study aims to clarify the advantages and disadvantages of the current development of 
eel industry in Guangdong, which can promote the upgrading and optimization of Guangdong eel industry cluster to achieve 
sustainable development. Currently, the local quotient and concentration coefficient of Guangdong eel industry reached 
3.16 and 4.93, showing the advantages of high industrial concentration and specialized production. However, the supply 
coefficient of eel fry in the upstream of Guangdong eel industry chain is only 0.0045, and the supporting role of leading 
enterprises in eel industry needs to be further enhanced. Based on these above, the following development countermeasures 
are put forward, such as strengthening the supporting capacity of leading enterprises in Guangdong eel industry cluster, speeding up the construction of eel industry service system in Guangdong Province, and strengthening the close cooperation with 
other major eel producing areas.]]></description>

Degree of Agricultural Insurance and Agricultural
Modernization in Shandong Province]]></title>
<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=202206018&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】A sound agricultural insurance system plays an important role in avoiding or dispersing the 
risks of agricultural operation and promoting the development of agricultural modernization. It is crucial to explore the 
coupling coordination and gray correlation between agricultural insurance and agricultural modernization to accelerate 
the realization of high-quality development of agriculture.【Method】Based on the relevant data of agricultural 
insurance and agricultural modernization in Shandong Province from 2010 to 2019, the research used the coupling 
coordination model to reveal the coupling interaction and influencing factors between the two systems, and used the gray 
association method to analyze the influence of agricultural insurance on the development of agricultural modernization.【Result】 The comprehensive development score of agricultural insurance and agricultural modernization in Shandong 
Province showed an increasing trend, and the coupling corordination degree of agricultural insurance and agricultural 
modernization gradually improved from serious imbalance to high-quality coordination, with the coupling degree increasing 
noticeably from 0.329 in 2010 to 0.875 in 2019. The gray correlation coordination degree of each agricultural insurance system 
index and agricultural modernization index was relatively high, all above 0.7. Among them, the proportion of agricultural 
insurance premium income in property insurance, the depth of agricultural insurance premium income and agricultural 
insurance premium income and agricultural modernization had relatively high correlation, which has become the main 
influencing factors.【Conclusion】Based on the above results, it is proposed to improve the market-oriented agricultural 
insurance mechanism, improve the service management level, increase the publicity of agricultural insurance and expand 
the coverage of agricultural insurance, promote the integration and coordinated development of agricultural insurance and 
agricultural modernization and other countermeasures and suggestions.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The study was conducted to promote the high-quality development of agriculture at county 
level in the Yellow River basin, deepen the understanding of agricultural inputs and outputs, and improve the increasingly 
tight constraints on agricultural resources and the deterioration of agricultural ecological environment, and to propose 
optimized development ideas and countermeasures.【Method】The land use changes of Dali County, Shannxi Province were analyzed by the land use transfer matrix, then the emergy analysis (EMA) method was used and an index system was 
constructed, several indexes based on the emergy flow were defined and calculated, the operational characteristics of agroecosystems in 2014 and 2019 and the sustainability of development were characterized and measured, the emergy values of 
inputs and outputs in agro-ecosystems were quantitatively analyzed and evaluated output emergy, then the key factors that 
constrain the sustainable development of agro-ecosystems were identified.【Result】Compared with the base period of 2014, 
the emergy self-sufficiency rate of the agro-ecosystem in 2019 (year of land use planning) decreased from 18% to 13%, and 
the net emergy output rate decreased from 2.10 to 1.27, the sustainability index decreased from 0.90 to 0.35, the emergy value 
investment rate increased from 4.51 to 6.71, the environmental load rate increased from 2.33 to 3.61, the emergy value density 
from 1.93×1012 sej/m2 to 2.69×1012 sej/m2
, and the emergy consumption per capita from 1.03×1016 sej/person to 1.41×1016
sej/person. In 2019, compared with 2014, the area of forest land, artificial land and water bodies decreased by 5.75%, 0.60% 
and 60.06% respectively, and the area of grassland, cultivated land and wetland increased by 19.80%, 1.44% and 21.15%, 
respectively.【Conclusion】Land use change is not the main factor influencing the change of agricultural output emergy, the 
overall development level of agriculture in Dali County is also increasing while the costs of agricultural production are also 
increasing, and the process of agricultural modernization is relatively rapid, which is a consumer-oriented economic system. 
The investment in non-renewable industrial auxiliary energy values represented by pesticides, diesel and chemical fertilizers 
has increased significantly, increasing the pressure on the agricultural ecological environment.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The creation of modern agricultural industrial parks is a major initiative to promote high-quality 
agricultural development and accelerate the modernization of agriculture and rural areas in China in the new era. In order 
to comprehensively implement the strategy of rural revitalization and promote the prosperity of rural industries, in 2010, 
the state launched the creation of modern agricultural demonstration zones, and in 2017, the state launched the creation of 
modern agricultural industrial parks. Among them, the government plays a diversified role as a planner, service provider 
and coordinator in the creation and development of modern agricultural industrial parks. In terms of fiscal support, financial 
support, talent introduction, public services and regional brand building, the government has played an important role in the construction and development of modern agricultural industrial parks by introducing a series of policies that benefit the 
people and taking corresponding measures, which has made the development of modern agricultural industrial parks achieve 
remarkable results. Taking the modern agricultural industrial parks in Western Guangdong as an example, the study analyzes 
the management modes of the modern agricultural industrial parks and the effectiveness of the government’s role, summarizes 
the experience and shortcomings of the government’s role in the development of the modern agricultural industrial parks, and 
puts forward targeted countermeasures and suggestions for the government’s problems in the areas of preliminary planning, 
long-term supervision, preliminary promotion and market integration. It is of great significance for government departments to 
vigorously promote the sustainable development of modern agricultural industrial parks based on the principle of “co-creation 
and sharing”.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[China is a country with the largest pig industry and the largest consumer of pork. The pork production in China 
directly affects the “vegetable basket” of urban and rural residents. With the rapid economic development, the scale of pig 
industry in Guangdong tops the forefront of the country. However, the pig production of Guangdong is not enough to meet the 
demand of local people, and pigs were brought in from neighboring provinces of Guangxi, Hunan, Hainan, Fujian and Jiangxi 
each year. Understanding the changes of pig production in Guangdong will help to adjust production mode and increase pig 
production. After thorough analysis on the pig production data in Guangdong Rural Statistical Yearbook, the results showed 
that the pig production capacity of Guangdong Province was increased rapidly at the early stage of the reform and opening-up 
and to relatively stable after the “11th Five-Year Plan”. Pig production capacity was gradually transferred from the Pearl 
River Delta, the rapid economic development region, to the western and northern of Guangdong. Furthermore, the efficiency of 
pig breeding has been continuously improved and the pig breeding scale is transforming from the initial phenomena of “small, 
scattered and disorderly” to large-scale and intensive. At present, the pig industry in Guangdong is faced with difficulties in 
land use, great pressure on environmental protection, persistent epidemics, high breeding costs and other problems. In view of 
the problems existing in the pig industry in Guangdong Province, corresponding development countermeasures are proposed to 
promote the pig industry to the development of high efficiency, industrialization and ecology, which include strengthening the prevention and control of major epidemics to create a safe production environment; strengthen ing the transformation of breeding 
equipment to improve production efficiency and production safety; reasonably planing pig breeding to promote ecological breeding; 
optimizing policies and regulations to improve the breeding willingness of farmers.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】It is of practical value to explore the status of idle homestead in villages and towns in 
hilly areas of Sichuan Province for revitalizing idle rural land and boosting rural revitalization.【Method】Through field 
researches, the spatial characteristics of idle homestead in Lidu Town, Nanchong City were analyzed, the idle types and 
causes were summarized, and related countermeasures were put forward.【Result】The idle homestead in Lidu Town had a 
time span of 2-15 years, and the idle time of 5-10 years accounted for the largest proportion. The idle area was 30.19 hm2
, accounting for 0.29% of land area of the whole town. The proportion of idle homestead area at regional scale in the original town 
and township decreased clockwise from the original Xinchang Township, which had an obvious spatial scale effect. The number 
of idle homestead at village scale was showed as: “50-100”>“less than 50”>“100-150”>“more than 150”, and the 
area and proportion were both showed as: “more than 150”>“50-100”>“100-150”>“less than 50”. The idleness 
of homesteads in Lidu Town could be divided into four types: out-migrant for work, building new houses without tearing down 
old ones, rural population buying houses in cities and inheriting but not using, the number of idleness due to out-migrant for 
work was the largest, which was caused by the unsound homestead law enforcement supervision mechanism, the imperfect 
exit mechanism and the uneven flow mechanism. In essence, it was the result of the unbalance between the rural population 
structure change and homestead use under the urban-rural dual system.【Conclusion】Starting from assisting regional rural 
revitalization, countermeasures and suggestions of activating the main body of homesteads to participate in endogenous power, 
perfecting the management system of rural homesteads, and exploring the multi-functional use mode of idle homesteads were 
proposed.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】Cultivated land, responsible for the development of rural industries, social security and 
ecological conservation, is pivotal to the implementation of the Rural Revitalization Strategy. However, heavy metal contamination of cultivated land seriously affects the continuation of this process. The diversified governance system of heavy 
metal pollution in cultivated land is an important tool to activate the elemental resources of rural cultivated land, ensure the 
safety of food production and promote rural revitalization. Carrying out the treatment of heavy metal pollution in cultivated land 
according to local conditions is an urgent theoretical and practical problem to be solved. 【Method】In order to guarantee the 
implementation of the Rural Revitalization Strategy, the study explored the diversified governance system from the perspective 
of heavy metal pollution in cultivated land of Dabaoshan mining area, and analyzed the difficulties and problems faced by the 
diversified governance mode of cultivated land heavy metal pollution in the mining area. 【Result】The current situation of 
heavy metal pollution governance of the cultivated land in Dabaoshan Mountain is still not optimistic, and there are some main 
problems such as the absence and weakness of the main body of control, especially the failure to manifest main position of 
farmers, the lack of social funds and the imperfec t system of diversified participation. In response to the problems that exist in 
the current situation of heavy metal pollution governance, the following strategies are proposed: (1) Realizing self-remediation 
of cultivated land by farmers through changing inertial thinking. (2) Giving full play to the function of social organizations 
by improving the diversified governance model of heavy metal pollution in arable land. (3) Introducing more third-party 
enterprises and institutions to stimulate the vitality of market entities. (4) Strengthening technological researches and forming 
a comprehensive pollution prevention and control scheme from the source to the end.【Conclusion】The present results can 
provide important reference values and guidance for the formulation of local cultivated land protection policies in heavy metal 
contaminated mining areas.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】To study the factors affecting consumers’ intention to use the digital traceability 
platform for agricultural products quality and safety, boost the promotion and application of digital traceability platform 
for agricultural products, further improve the quality and safety level of China’s agricultural products and realize highquality development of agricultural products in China.【Method】A total of 291 valid questionnaires were collected 
through the online questionnaire distribution platform. And the research model of knowledge, perceived usefulness, 
attitude and use intention of digital traceability platform was constructed. Based on the technology acceptance model, the 
factors affecting consumers’ intention to use the digital traceability platform for agricultural products quality and safety 
was studied.【Result】The empirical results show that perceived usefulness has a significant positive impact on attitude (H1: β=0.345, P<0.001) and intention to use (H2: β=0.164, P<0.001), attitude has a significant positive impact on intention to use 
(H3: β=0.161, P<0.01), knowledge has a significant positive impact on perceived usefulness(H4: β=0.676, P<0.001) and attitude 
(H5: β=0.394, P<0.001), but knowledge does not have a direct impact on intention to use (H6: β=0.060, P=0.323). Through 
the test of intermediary effect, it is found that knowledge has a significant indirect influence on the intention of use through 
perceived usefulness (β=0.111, P<0.051, CI: 0.025-0.236) and attitude (β=0.363, P<0.05，CI: 0.000-0.116). In addition, 
knowledge indirectly affects the intention of use through perceived usefulness and attitude (β=0.038, P<0.05, CI: 0.000-0.107).
【Conclusion】when promoting the digital traceability platform, we should pay attention to conveying relevant knowledge and 
information of the digital traceability platform to consumers, guide consumers to form useful knowledge of the digital traceability 
platform, and cultivate their positive attitude towards the digital traceability platform.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The study was conducted to improve the detection accuracy of muskmelon picking robot in 
greenhouse under complex light changes and branch and leaf occlusion, and realize the spatial coordinate positioning of 
detection targets.【Method】Based on YOLOv3, the study explored the impacts of optimizing the combination of different 
backbone networks, head and neck network structures and bounding box loss function on the model detection performance, 
established a target detection network model YOLOResNet70 under severe muskmelon occlusion, and then fused the 
model with Intel RealSense D435i depth visual sensor for target space positioning.【Result】With ResNet70 as the 
backbone network, YOLOResNet70 had the best performance with the combination of SPP (Spatial pyramid pooling), CIoU 
(Complete Intersection over Union), FPN (Feature Pyramid Network) and NMS (Greedy non-maximum suppression). The 
average accuracy (AP) of the model reached 89.4%, which was better than 83.3% of YOLOv3 and 82% of YOLOv5, and the 
detection speed (61.8 frames/s) was 14% faster than that of YOLOv4 (54.1 frames/s).【Conclusion】 Through the detection and test of occluded muskmelon images under different lighting conditions, it shows that the YOLOResNet70 model has good 
robustness, and the model is fused with Intel RealSense D435i depth visual sensor to achieve the spatial positioning coordinates 
of muskmelon, which is consistent with the manual measurement result. It provides theoretical and model support for target 
detection and spatial positioning of muskmelon picking robot.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Green agricultural development is the connotation and requirement of high-quality agricultural development. 
The measurement and research of green total factor productivity (GTFP) of agriculture has important references for measuring 
the level of high-quality agricultural development. Guangdong Province is divided into four regions, namely, the Pearl River 
Delta region, the east, west and north regions. The city-level data of Guangdong Province in 2007-2017 is used to measure 
the agricultural GTFP in Guangdong Province, and the agricultural GTFP is analyzed from the time trend and spatial 
distribution , the results show that: (1) The agricultural GTFP in Guangdong Province shows an upward trend year by year, 
the technical improvement and technical progress are the main sources of agricultural GTFP growth, but the growth rate is on the decline; (2) The level of agricultural green productivity varies among the four regions in Guangdong Province. The Pearl 
River Delta region ranks the top, followed by the north Guangdong region, the east Guangdong region and the west Guangdong 
region. However, the overall level of these three regions is not significantly different. (3) There are also great differences in 
agricultural GTFP levels among cities within the four regions. Based on the above conclusions, some suggestions to improve 
the agricultural GTFP in Guangdong Province are put forward: (1) always adhering to the“five in one”overall strategic goal, 
implementing the rural revitalization policy, following the green development concept proposed by the Party Central Committee, 
paying attention to constraints of environmental factors on agriculture, and effectively promoting the negative growth of fertilizer 
and pesticide use; (2) Transforming the mode of agricultural production and operation and promoting the progress of green 
science and technology in agriculture in many aspects, including increasing financial support for green science and technology 
research and development in the agricultural field and establishing a system for the training and introduction of agricultural 
talents; (3) Implementing the strategy of coordinated regional development, giving play to the effect of agglomeration and 
amplification, and promoting the coordinated development of green agricultural regions.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】In order to provide appropriate irrigation reference basis for the planting of Scindapsus 
aureus and reduce the waste of water resources in agricultural production, the relationship between the growth of S. 
aureus and water stress was explored.【Methods】S. aureus was selected as the experimental material and treated with 
different gradients of water stress in four groups. The CI-600 plant root growth monitoring equipment was used to collect 
and analyse the relationship between root number, root length, root area, root volume and the water stress, respectively, 
and the Excel software was used to process data then draw the relation curve between relevant root parameters and soil water stress. The relationship between plant root growth and water stress was finally obtained by using the least square 
method and quadratic term fitting method for model fitting.【Result】Most of the models fitted by quadratic terms have R2
greater than 0.9, which indicates a high degree of fitting. The root number, root area and root volume are growing the fastest 
under the humidity of 35%. Humidity in the range of 25%-35% is conducive to the increase of root length. According to 
the fitting curves, the two indexes of root number and root length are consistent under 25% and 35% humidity conditions. 
Moreover, water stress affects root area and root volume by affecting root length and root number. Roots also depend on 
the expansion of diameter to obtain effective absorption area while elongating. The change of root volume is related to the 
changes of root number and root diameter.【Conclusion】In conclusion, the optimum growth humidity for S. aureus is 35%. 
What’s more, drought stress（15%）and flooding stress（45%）have adverse effects on root growth. Finally, under different 
water stress, the physiological indexes of root system have different trends and behaviors, and the indexes are interrelated 
and complementary to each other so as to form a harmonious growth system. Therefore, when cultivating plants, humidity 
should be controlled in the appropriate range to obtain the high quality biological characteristic values of the plants, then to 
ensure its economic benefits.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】Aiming at the difficulty in recognizing and segmenting multiple broilers in complex 
environment, a segmentation method for depth map of multiple broilers based on deep learning was explored.
【Method】By using the depth camera, the depth map of broilers in different postures（standing, prone, looking 
up, looking down, etc.）were collected in the natural environment through different shooting angles（top, front 
and side）, and the depth map were accurately marked by CVAT labeling software. A broiler depth map dataset 
was established, with a total of 4 058 depth maps. Five neural networks, including FCN, U-NET, PSPNet, 
DeepLab and Mask R-CNN, were used to recognize and segment broiler depth maps. Based on the predicted 
results of test sets, the performance of different models were compared and evaluated to realize the recognition 
and segmentation of broiler depth maps.【Result】The recognition and segmentation accuracy of Mask R-CNN 
neural network model is 98.96%, the recall rate is 97.78%, the F1
 score is 95.03%, and the intersection-overunion is 94.69%, all of which are the optimal values of the five models.【Conclusion】The algorithm based 
on Mask R-CNN is simple and fast, and it can realize the automatic recognition and segmentation of broilers 
accurately and has good robustness to the shielding of broilers, which can basically meet the recognition and segmentation requirements for the prediction of the evenness of chicken flocks in the chicken farm. It promotes the 
application of computer vision in modern agriculture, and provides theoretical and practical bases for chicken farm 
operations such as flock counting, flock evenness prediction and welfare breeding of broilers.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=202201020&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】 The study is conducted to better learn and draw lessons from the beneficial experience of urban 
agriculture development in domestic advanced cities, and to further clarify the strategic thinking and path of urban agriculture.
【Method】The advanced cities in China such as Guangzhou, Beijing, Shanghai, Hangzhou, Chongqing and Chengdu are 
selected for field investigation and literature comparative study.【Result】The six megacities have different natural conditions 
and resource endowments, and their agricultural development has certain similarity and different regional characteristics, 
which basically represents the development of urban agriculture in the Yangtze River Delta, Pearl River Delta and southwest 
China. In 2019, the added value of primary industry of the six megacities accounted for 1.1%, 0.3%, 0.3%, 2.1%, 7.6% and 3.6% of the GDP of these megacities, respectively.【Conclusion】Based on the comparative analysis of the domestic advanced 
cities, Guangzhou has some major shortcomings in urban agriculture development: the underperforming advantageous practice of 
integrated city-empowered agriculture, the low level of scaling up and systematizing the agricultural industry, and the weak capacity 
of developing the whole agricultural industry chain. Based on the above explanations, the suggested strategic ideas and directions 
are as follows: to develop pivotal urban agriculture to transform it from small agriculture to big agriculture, from decentralized 
agriculture to intensive and centralized agriculture, from extensive agriculture to refined and characteristic agriculture, and from 
traditional mass products to branded agricultural products; to expand the whole agricultural industry chain to improve agricultural 
competitiveness; to strengthen industrial integration to achieve mutual empowerment and support between industries; to cultivate 
“sophisticated and advanced” and “famous and special” green agricultural products; to develop leisure agriculture and rural 
tourism, and to focus on building modern agricultural industrial parks.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=202212019&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】China is the main country in pork production and consumption. In recent years, pork price fluctuations have shown the trend of accelerating frequency and increasing amplitude. The fluctuation of pork price not only increases the risk of farmers’ income, but also affects the living of the general public. Correctly identifying the influencing factors of pork price fluctuations and making accurate predictions help to guarantee the well-functioning of the market.【Method】The multi-dimensional association rules were used to quantitatively analyze the correlation and influencing degree of 16 influencing factors in five main aspects including the industrial chain of pig breeding and processing, market of substitutes, changes in macroeconomic environment, emergencies and international market environment with pork price fluctuations. High correlation factors selected by mining were used as model input variables, and the support vector regression 
machine was used to construct a multi-step prediction model for pork price fluctuations.【Result】The top three factors most related to pork price fluctuations are pig epidemics, pig prices and piglet prices, with confidence levels of 1.00, 0.93 and 0.82 respectively. The top three factors have the greatest impact on pork prices are pig epidemics, pork production and pork supplied to the market, with the improvement degrees of 1.84, 1.67 and 1.67, respectively. Compared with the baseline prediction model, with 12 highly correlated influencing factors as model inputs, the Root Mean Square Error (RMSE) is reduced by 29.11%, and the Mean Absolute Percentage Error (MAPE) is reduced by 16.00%.【Conclusion】The use of multi-dimensional association rules for variable selection not only reduces the number of variables, but also effectively improves the prediction accuracy. Given the vital influence that pig epidemic imposes on price volatility, authorities should raise the awareness of risk prevention of animal diseases.]]></description>

requirement of real-time detection of various apple bark diseases in orchards.【Method】The images of ring rot, canker 
and dry rot were collected through network searching and field shooting. After amplification and labeling, the training set 
and test set were divided according to the ratio of 8 ∶ 2. The YOLOv5s algorithm was used to train the apple bark disease 
recognition network model. The lightweight network model trained was deployed on the Android end, and the corresponding 
APP interface was designed to realize the rapid diagnosis of ring rot, canker and dry rot. 【Result】The recognition effect of the deep learning network obtained after training is good, the accuracy rate is stable at 88.7%, the recall rate is stable at 85.8%, 
and the average accuracy value is stable at 87.2%. Among them, the accuracy of canker is 93.5%, dry rot is 88.2%, and ring rot 
is 84.3%. After it is deployed on the Android end, the processing time of each disease picture is less than 1s, and the detection 
confidence is 87.954%. The lightweight recognition system not only realizes the rapid detection of the three diseases, but also 
ensures high recognition accuracy.【Conclusion】The YOLOv5s network weight model is small, which can be easily deployed 
on the Android. The APP designed based on YOLOv5s is simple to operate with high detection accuracy and fast recognition 
speed, which is helpful for precise management of orchards.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】The study was conducted to establish a comprehensive evaluation index system for ecological 
protection and high-quality economic development in Northwest China, and measure the coupling coordination level of 
the“ecology-economy”system in Northwest China, with a view to providing countermeasure and suggestions for promoting 
the coordinated development of the“ecology-economy”system and its elements.【Method】Based on the panel data of 
five provinces in Northwest China from 2008 to 2020, the entropy method and coupling coordination degree model were used 
to measure the coupling coordination level of the“ecology-economy”system in Northwest China, and cluster analysis was 
used to divide the coupling degree of the“ecology-economy”system in Northwest China into six levels.【Result】The time 
series characteristics of the coupling coordination degree of the“ecology-economy”system in Northwest China increased 
steadily during the investigation period, and the coordination level gradually transited from mild imbalance and low-level 
coordination to high-quality coordination. The spatial characteristics were shown in the coupling coordination degree of 
the“ecology-economy”system, presenting the characteristics of Shaanxi > Gansu > Xinjiang > Qinghai > Ningxia. The five 
provinces in Northwest China reached and maintained the basic coordination level of class Ⅴ from 2016 to 2020. Shaanxi 
first entered the high-quality coordination level of class Ⅵ in 2020. The coupling coordination degree of the“ecology 
economy”system of Ningxia and Qinghai fluctuated and increased.【Conclusion】There is a strong spatial heterogeneity in Northwest China. We should improve the“ecology-economy”system and its coordinated development mechanism from three 
aspects: endogenous innovation, consumption upgrading and government promotion.]]></description>

cooperatives and an inevitable trend to promote the prosperous development of cooperatives. Therefore, exploring the motives 
and obstacles of the establishment of farmers’ cooperative associations is crucial for accelerating the high-quality development of 
cooperative associations.【Method】Based on the original interview data of 24 farmers’ cooperatives, 6 cooperative associations 
and 30 members of cooperative associations, this study uses the Grounded Theory to qualitatively analyze the motivation and 
obstacle factors of cooperatives to establish cooperative associations, by fully abstracting the original interview data, through the 
three-level coding process of open coding, spindle coding and selective coding, constantly comparing and summarizing, and 
thoroughly analyzing the logical relations among various categories of concepts, finally, the model of motivation and obstacle 
factors of farmers’ cooperative associations is constructed.【Result】The six principal categories of profit motivation, value 
motivation, interactive obstacle, management obstacle, quality obstacle and social environment in the construction model have 
different degrees and directions of influence on the formation behavior of cooperative associations. Among them, the profit 
motivation and value motivation are the intrinsic motivation of the formation of the cooperative associations, the representative 
description of A1-A3 cooperatives is chosen to test the results. While interactive obstacle, managerial obstacle, and diathesis 
obstacle inhibit the cooperative’s willingness to form associations, the representative description of A4-A8 cooperatives is used 
to verify the results. Social environmental factors play a moderating role in the transformation from willingness to cooperate 
behavior, the representative description of A9-A15 cooperatives is chosen to analyze and verify the results. The results show 
that the differences in the factors affecting the formation of cooperatives are mainly in the following four aspects: from the focus 
on quantity cooperation to quality cooperation; From the focus on production front-end cooperation to the whole industry chain 
cooperation; From passive cooperation to active cooperation; From the form of cooperation to actual construction.【Conclusion】
Based on research results, the following countermeasures and suggestions are put forward: Strengthening the profit motivation 
and value motivation of the cooperative establishment of the association; Strengthening the interactive communication in the 
establishment of cooperatives association; Standardizing the internal management of the leaders in the formation of cooperatives 
association; Playing the leading role of the chairman in the process of establishing the association; Strengthening the 
government’s role in promoting the establishment of the association.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Modern agricultural industrial parks are based on the large-scale development of traditional agriculture, 
which are a new carrier as agricultural modernization promotion, rural revitalization and supply-side structural reform, 
also are vital to the “three rural” work. The construction of modern agricultural industrial park involves a lot of contents, 
requires a large amount of funds and a long period. Since the country proposed the construction of modern agricultural 
industrial parks, governments at all levels have attached great importance to organizing financial investment, leveraging 
social capital, and initiating the construction of industrial parks at all levels. Guangdong has taken the lead in utilizing financial investment to implement the construction of provincial-level modern agricultural industrial parks, with the overall 
goal of building high standard industrial parks, combined with local natural endowments and market demands, scientifically 
designed and systematically planned various industrial parks at the provincial, municipal, county and town levels, initially 
forming a tiered development layout, and making industrial park construction as one of the main contents of implementing 
the rural revitalization strategy. Through multiple rounds of industrial park construction, Guangdong has built and innovated 
the system of project approval review, fund management, supervision and acceptance in the industrial parks, which provide 
institutional guarantees for the efficient use of financial funds. Through financial investment, Guangdong Province has built 
modern agricultural industrial parks, enhanced the attraction of agricultural industry, levered social capital, and injected 
inexhaustible impetus into agricultural modernization. The special investment of financial funds has played a huge supporting 
role in the construction of the industrial park, effectively ensuring the smooth implementation of the industrial park project, and 
accumulating certain experience in the use and management of financial funds. The rational and effective use of financial funds 
is also the core of industrial park construction. Guangdong has formulated a series of management measures for the use of funds, 
clearly defining the scope and plan of fund use, improving the safety and efficiency of financial fund use, and ensuring the 
supporting role of financial funds in the construction of industrial parks. Based on the current situation of agricultural industry 
and industrial park construction in Guangdong, this paper analyzes the problems existing in the process of financial support for 
industrial park construction, and puts forward corresponding countermeasures and suggestions, in order to provide reference for 
the high-level construction of modern agricultural industrial park in Guangdong.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[In order to adhere to the consolidation of household contracted management, innovate and improve the dual management system combining centralization and decentralization (DMS), and give full play to the function and role of rural collective organizations in the centralization of small farmers, the status of economic development of 47 rural collective organizations and 4 practical models that can be copied and promoted in Guangxi were studied by adopting methods such as literature combing, field survey, case demonstration and clustering and comparison and statistical analysis. The research found that in recent years, although the village collectives in Guangxi have completed the equity reform of collective assets, and the collective incomes have increased, the overall operation vitality is still relatively weak, the organization and service degree for small farmers is relatively low, and the adhesion between village and household in production and operation is small. The 4 practical models analyzed show that, compared with capital-oriented business entities such as enterprises, village collective economic organizations have stronger adaptability to the management of small farmers, being important new business entities to organize and serve small farmers. Therefore, it is suggest that it should be made good use of the results of the “three transformations” reform of rural collective assets, to carry out the pilot of the innovative development of the DMS, to speed up the supply of laws and regulations of village collective economic organizations, to establish a mechanism of financial investment to cover village collectives and to extend to small farmers preferentially, and to develop the village collective economy with the support of village-equity economic cooperatives so as to organize and drive small farmers to integrate into the development of modern agricultural industrialization.]]></description>

<link><![CDATA[http://gdnykx.cnjournals.org/gdnykxen/ch/reader/view_abstract.aspx?file_no=202302017&flag=1]]></link>
<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[【Objective】Digital economy has a profound impact on China’s economic development and can accelerate the process of agricultural modernization. The research theoretically explores how the digital economy drives agricultural modernization, constructs a comprehensive evaluation index system of digital economy and agricultural modernization, analyzes the impact of digital economy on agricultural modernization from a national perspective, and puts forward relevant policy recommendations.【Method】Based on the panel data of 31 provinces (cities, autonomous regions) in China from 2011 to 2020, the levels of digital economy and agricultural modernization were calculated respectively, the internal mechanism of the impact of digital economy on agricultural modernization was analyzed, and the heterogeneity and sub-test of digital economy on agricultural modernization were empirically tested.【Result】(1) Digital economy can drive agricultural modernization; (2) Digital economy can indirectly promote agricultural modernization through labor transfer and human capital investment of farmers; (3) In terms of various dimensions of agricultural modernization, digital economy can promote agricultural production modernization, agricultural modernization output and sustainable development of agricultural modernization, however, its impact on agricultural management modernization is not obvious; (4) Focusing on the development of agricultural modernization in various regions, compared with the eastern and central regions, the western regions have gained 
higher dividends through digital economy.【Conclusion】The digital economy has shown obvious differences in the process of deepening agricultural modernization in various regions of the whole country. On the basis of the existing achievements in the development and construction of the digital economy, we should continue to promote digital technology to empower agriculture, improve the quality of agricultural talents, deepen the concept of green and organic agriculture, develop digital management strategies in the operation and management of the digital economy that has not yet reflected the achievements, widely adopt e-commerce and online marketing models, push the branding, industrialized and scaled development of agricultural products according to local conditions and local characteristics, deepen the influence of digital economy on agricultural operation and management, and improve the internal mechanism of digital economy to drive agricultural modernization. In addition, the government should adopt different policies according to the development degree of agricultural modernization in different regions, and implement a differentiated and stepwise development strategy.]]></description>
