稻花香2号“3414”肥效试验初报

First Report on Fertilizer Efficiency of "3414" on Daohuaxiang-2

通过对稻花香2号"3414"田间肥效试验,得出稻花香2号的产量与施肥量的三元二次回归方程,获得最佳施肥效应模型。结果表明:稻花香2号的产量与N、P、K的施用量之间有明显的回归关系。最佳施肥量为:N:12.29 kg/667 m2,P:6.78 kg/667 m2,K:6.05 kg/667 m2,最佳产量为554.96 kg/667 m2。

The ternary quadratic regression equation between yield and fertilizing quantity of Daohuaxiang-2 were get by fertilizer efficiency of ＂3414＂ to reach the best model for fertilization. The result indicated that obvious regression relationships can be achieved between yield and N, P, and K. The best fertilizer amount were N： 12.29 kg/667 m2, P： 6.78 kg/667 m2, K： 6.05 kg/667 m2, it can reach the best yield which was 554.96 kg/667 m2.
