| 摘 要： | 对影响黄淮地区麦套棉花产量和效益的人为可控因子中的施纯N量、施P2O5量、施K2O量、密度、化控5因子进行了研究。通过建立数学模型,明确了影响产量和效益的因子主次顺序为:密度>氮肥>钾肥>化控>磷肥。其最佳组合方案:施纯N180～195kg/hm2,P2O530～60kg/hm2,K2O150～165kg/hm2;移栽密度5.25万～5.52万株/hm2;用缩节胺30～45g/hm2,于盛蕾期、盛花期或封顶时化控2～3次。

| Abstract: | The five man-made controlled factors,which influenced the output and benefit of interplanting cotton with wheat in Huang Huai were: pure N, P2O5, K2O, planting density and chemical controlling, were discussed. By mathematics model, it defined the order of influencing factors: deasity>nitrogenous fertilizer>potash fertilizer>chemical controlling>phosphate fertilizer. |
