摘　　要：采用四因素五水平二次正交旋转回归试验方法,在影响甘蓝型黄籽油菜产量的施肥诸因素中,选择氮、磷、钾、硼的施用量作为生产上的决策变量,以油菜产量为目标函数,所得实验结果通过微机计算,建立了二次回归数学模型。通过对模型的主效应、交互效应的分析表明:施氮量、施磷量和施硼量是影响产量的主要控制因子,并根据试验结果筛选出最佳农艺措施方案。Regression method of orthogonal gyration combination with 4 factors and 5 levels was employed in this study. Of the factors influencing rapeseed yield, application rates of N, P, K and B were chosen as the variants for decision-making in production, and rapeseed yield was adopted as the target function. The data obtained in the experiment were analyzed with the micro-computer and a quadratic regression model was established. Analysis of the main effect and reciprocal effect of the model showed that the rates of N, P and B were the main controlling factors influencing the yield of yellow-seeded rapeseed, and the optimal combination in fertilization practice for high-yield cultivation is recommended.
