水稻“3414”肥效试验研究

Experiment Research of “3414″ Fertilizer Effect in Rice

水稻"3414"肥料效应试验结果表明,适量增施氮肥、磷肥、钾肥可以提高水稻的产量,但是过量施用都会导致产量下降,效益降低;通过建立回归方程并对回归方程的各项数据进行分析显示,水稻产量与氮肥、磷肥、钾肥的施肥量之间存在着显著的回归关系。当施肥水平为纯N 210 kg/hm2、P2O590 kg/hm2、K2O 210 kg/hm2时,可获得最大产量8 850 kg/hm2,最高效益21 917元/hm2。

The results of the experiment of ＂3414＂ fertilizer effect on rice showed that, applying proper amounts of N, P and K could increase the yield of rice,but excessive use would lead to a decline in output,lower efficiency.The regression equation was established and the data of the regression equation were analyzed ,it showed there was a significant regression relationship between rice yield and fertilizer amount of N ,P and K fertilizers. The yield was the highest （8 850 kg/hm2）with the pure N of 210 kg/hm2, P2O5 of 90 kg/hm2, K2O of 210 kg/hm2, the benefit was highest （21 917 yuan/hm2）.
