中文摘要: |
为建立适于恩平市水稻生产的测土配方施肥指标体系,在恩平市恩城锦岗垌和大田岭南垌开展“3414”小区试验和中区验证试验。结果表明,在恩平市恩城锦岗垌试点和大田岭南垌试点水稻最高施肥量配比(N∶P2O5∶K2O)分别为1∶0.32∶0.56 和1∶0.60∶1.39,N、P2O5、K2O 养分按照不同区域推荐每公顷N、P2O5、K2O 最高用量分别为85.74、51.55、103.61 kg 和185.18、57.94、103.61 kg。按2012 年N、P2O5、K2O 的
市场价格与稻谷价格计算,恩平市恩城锦岗垌试点和大田岭南垌试点水稻每公顷 N、P2O5、K2O 适宜用量分别为84.48、50.51、99.83 kg 和174.8、53.40、99.83 kg。 |

In order to establish an index system of formula fertilization by soil testing applied in the rice production
in Enping city,the "3414" small plot experiment and middle validation test were carried out respectively in Jingang plot
(Small) and Datian Lingnan plot(Middle). Results indicated that the highest matching rate of fertilizer application
(N∶P2O5∶K2O) in the two experiment plots were 1∶0.32∶0.56(S) and 1∶0.60∶1.39(M). The highest fertili
zing amount of N,P2O5,K2O nutrients recommended for the two plots were 85.74,51.55,103.61 kg(S)and 185.18,
57.94,103.61 kg(M)per hectare. Taking the market prices of N,P2O5,K2O and rice price in 2012 into calculatio
n,the appropriate fertilizing amount of N,P2O5,K2O for the two testing plots should better be 84.48,50.51,99.83 kg
(S) and 174.81,53.40,99.83 kg(M)per hectare. |
