祁县小麦“3414”肥料效应试验报告

在祁县农业综合开发项目区古县镇东城村进行小麦"3414"肥料效应试验,通过试验获得了当地种植小麦最高产量的施肥量、最佳经济效益的施肥量,并且比较了不同施肥模型的推荐施肥效果。结果表明,一元方程和三元二次方程的推荐值大致相同,其中,三元二次模型最大施肥量为N 388.20 kg/hm2,P2O5190.18 kg/hm2,K2O77.11 kg/hm2;采用线性加平台的最大推荐量为N 288.416 kg/hm2,P2O5 291.637 kg/hm2,K2O120 kg/hm2,二者差距不大。因此,在"3414"试验中,采用一元方程拟合是对三元二次方程最好的补充和优化。

The "3414" Fertilizer Response Test Report for Wheat in Qixian

The＂3414＂fertilizertest in wheat was conducted in the project zone of Qixian agricultural integrate development in Zhendongcheng of Qixian county.Through the＂3414＂fertilizer effect experimentation,the optimum fertilizer application for maximumyield and economic optimumwas obtained and the recommendation fertilizer effect of the different mathematical models was compared.The results showed that the one equation had roughly the same recommendation values,the maximus fertilization rate was N 388.20 kg/hm^2,P2O5 190.18 kg/hm^2,and K2O 77.11 kg/hm^2;the maximum recommendation values for the linear and platform were N 288.416 kg/hm^2,P2O5 291.637 kg/hm^2,and K2O 120 kg/hm^2,with no significant difference between them.It was concluded that in ＂3414＂test,application of one equation was the best supplement and optimization for ternary quadration equation.
