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.
