采用五元二次回归正交旋转组合设计,研究影响套作小麦产量的主要栽培因子的组合效应,建立数学模型,并对模型进行解析和计算机模拟寻优,得出产量为398.1326 kg/亩的最佳栽培组合:播期11月6日,密度15.6万/亩,碳铵用量37.7 kg/亩,过磷酸钙用量32.1kg/亩,追肥叶龄3.0片叶。
Using the five-factor quadratic regression orthogonal rotation combination design, the combined effects of the main cultivation factors affecting the yield of intercropping wheat were studied, a mathematical model was established, the model was analyzed and the computer simulation was optimized, and the yield was 398.1326 kg/mu. The best cultivation combination: the sowing date was November 6th, the density was 156,000 yuan/mu, the amount of ammonium bicarbonate was 37.7 kg/mu, the amount of superphosphate was 32.1 kg/mu, and the dressing age was 3.0 leaves.
