| 摘 要： | 本试验以“鲁白8号”为试材,采用二次正交旋转回归设计方法,试验结果经电子计算机运算,建立了播期、密度、氮肥、磷肥、钾肥五项技术措施与结球白菜的毛菜产量和净菜产量关系的数学模型。经过计算机模拟,在3125个方案中筛选出亩产净菜7000～9000kg的优化技术方案856个。具体农艺方案是,8月13日～14日播种,密度为2118～2162株/亩,亩施纯氮17.31～18.83kg/亩,P_2O_5 16.47～18.27kg/亩,K_2O 19.43～21.29kg/亩。

| Abstract: | A mathematical model of headed Chinese cabbage yield related to sowing date, density,NPK fertilizers was set up by using the quadratic orthogonal rotation design meth- od.The optimum scheme of a technical system to get 7000-9000kg commercial yield per mu was selected by simulating on an electronic computer,that is,sowing on August 13-14 at density of 2118-2162 plants/mu and application rates of pure NPK being 17.31-18.83, 16.47-18.27,19.43-21.29kg/mu,respectively. |
