摘　　要：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。Based on the theory of agricultural system engineering, our multifactorial and multilevel test with the rape variety Huiyou 50 was carried out using the quadratic regression orthogonal rotation design in order to establish the rape yield function models in multiple agronomic practices and obtain the optimization combination resulting in a rape yield of 150 kg or more per 666. 7m2 and so provide a scientific basis for attaining high yield in largescale rape culture.
