为探讨怀川916小麦超高产栽培条件下的氮、磷、钾最佳施肥配比，采用“3414”最优回归设计，田间试验测得的数据，建立了以产量为目标函数N、P、K因子效应的三元二次多项式回归方程，通过对方程的数学模拟因素取值的频率分析得出，小麦产量高于8600 kg/hm2的氮磷钾优化施肥配比为：施纯N 296.40~308.59 kg/hm2，P2O5115.97~133.06 kg/hm2，K2O 175.10~184.28 kg/hm2，并对2个因素互作效应及氮、磷、钾单因素效应进行了剖析。

To explore the best nitrogenous ,phosphate and potassic fertilizing ratio of super high yield for Huaichuan 916 wheat ,the best“3414”regression plan was adapted to get the data by field test and the ternary quadratic polynomial was set with equation yield as the objective function and the effect of N,P,K factors,by frequency analysis of mathematical simulation factor value to the equation,the results were that the best nitrogenous, phosphate and potassic fertilizing ratio of wheat yield higher than 8 600 kg/hm 2 was pure N 296.40~308.59 kg/hm2,P2O5 115.97~133.06 kg/hm2,K2O 175.10~184.28 kg/hm2,and analysis was carried out with the effect of two elements as mutual factor and nitrogen ,phosphorus,potassium as single element.
