研究选用优质杂交油菜新组合湘杂油２号进行四元二次回归旋转组合设计栽培试验，将种植密度、施氮量、施磷量、施钾量四种对油菜产量形成影响较大的农艺因素作为决策变量，产量作为目标函数，建立数学预测模型，通过分析各因素及因素间交互效应对产量的影响，利用计算机模拟寻优，提出了亩产达到１５０ｋｇ以上的高产栽培优化区间，即每亩种植密度１．１３—１．４０万株，施Ｎ量１９—１９．８５ｋｇ，施Ｐ２Ｏ５量７．５８—８．５５ｋｇ，施Ｋ２Ｏ量６．０１—７．７７ｋｇ。 In this study, a new combination of high quality hybrid rapeseed hybrids Xiangzayou 2 was used for quadratic quadratic regressive rotation combination design and cultivation experiment. The four agronomic traits, ie, planting density, N application rate, P application rate and K application rate, Factor as the decision variable and output as the objective function, a mathematical forecasting model was established. By analyzing the influence of each factor and the interaction effect on the yield, a computer simulation was used to optimize the yield. Mu planting density of 1.13-1.40 million, applying 19-19.85kg of N, applying P2O5 of 7.58-8.55kg and applying K2O 6.01-7.77kg.
