根据农业系统工程原理，运用二次回归正交旋转设计，进行油菜多因子多水平试验，以建立油菜综合农艺措施的产量函数模型。并通过计算机仿真模拟优选法，获取一组６６６．７ｍ２面积上产量１５０ｋｇ以上的优化组合，从而为大面积油菜高产栽培提供了科学依据。 According to the principle of agricultural system engineering, quadratic regression orthogonal rotation design was used to carry out multi-factor and multi-level experiment of rape to establish the yield function model of comprehensive agronomic measures of rapeseed. Through the computer simulation and optimization method, a group of 666.7 m2 on the yield of more than 150 kg of the optimal combination to obtain a large area of ​​rape high yield cultivation provides a scientific basis.
