| Abstract: |
| In recent years，in Huiyang District，the main line of work is“production stabilization，income
increase，structure adjustment，and institutional transformation.”They deeply carried out the action of zero growth
of chemical fertilizer，constantly explored the new model of saving and improving efficiency technology of chemical
fertilizers，vigorously promoted soil testing and formula fertilization technology，soil organic matter upgrading
technology，irrigation and fertilization technology，organic fertilizer instead of fertilizer technology，through
project support，government subsidy and expert guidance，etc. Since 2014，some achievements were achieved
in the popularization of saving and improving efficiency technology of chemical fertilizers. The concept of farmers'
fertilization was obviously changed. The quality of cultivated land was significantly improved，soil organic matter
rose by 0.1～0.9 g/kg，soil nutrients were obviously improved，soil structure was improved，and soil consolidation and acidification were improved. The fixed point survey showed that，the average amount of fertilizer used for
planting rice and yam was reduced by 23.1 and 32.4 kg per 667 m2，respectively，and the reduction was 33.82%
and 16.10%，respectively. Farmers' enthusiasm for the use of organic fertilizer gradually increased. The plan of zero
growth of chemical fertilizer，proposed by the Ministry of Agriculture，was initially realized. In general，the fertilizer
application amount（ pure quantity） reduced by 468 t（ reduction percent was 4%）. In Huiyang District，the supply
of agricultural products is effectively guaranteed，the green agriculture is accelerated and the Rural Revitalization is
steadily advancing. |
