摘要：

为使‘毕单17号’在高海拔地区获得高产，通过采用二次回归通用旋转组合设计的方法，对‘毕单17号’产量及其主要栽培因子——种植密度及N、P、K肥施用量之间的关系进行研究，并根据所得数据建立数学模型，解析各因子对产量的效应，通过计算机模拟寻优。结果表明，‘毕单17号’产量≥ 9850.00 kg/hm2的栽培因子优化组合方案为：密度65805~70620 株/hm2，施纯N量449.85~485.1 kg/hm2，施P2O5量273.75~326.25 kg/hm2，施K2O量224.64~323.85 kg/hm2，且对产量的影响顺序为：密度 > 氮肥（纯N） > 磷肥（P2O5） > 钾肥（K2O），且氮、钾肥有一定的互补作用。

Abstract:

In order to do that ‘Bidan17’ was high yield at high altitudes, using the second order regression current rotation design, the experiment was conducted with ‘Bidan17’ to study the effect of density and the cooperative relation among N, P and K. The mathematical model was established and the best cultivation scheme was gained. The results showed that: at high altitudes the cultivation scheme of ‘Bidan17’ yield more than 9850.00 kg/hm2 was that: density 65805-70620 plant per hm2, N 449.85-485.1 kg/hm2, P2O5 273.75-326.25 kg/hm2, K2O 224.64-323.85 kg/hm2,and the sequence was N > P2O5 > K2O of influence on the yield ,and N has certain complementation with K2O.
