| 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≥9850.00kg/hm2的栽培因子优化组合方案为:密度65805～70620株/hm2,施纯N量449.85～485.1kg/hm2,施P2O5量273.75～326.25kg/hm2,施K2O量224.64～323.85kg/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/hm 2 was that： density 65805-70620 plant per hm 2 , N 449.85-485.1 kg/hm 2 , P2O5 273.75-326.25 kg/hm 2 , K2O 224.64-323.85 kg/hm 2 , and the sequence was N P2O5 K2O of influence on the yield, and N has certain complementation with K2O. |
