摘　　要：采用三因素五水平二次回归通用旋转组合设计方法 ,得出宁夏引黄灌区利通区玉米膜上灌条件下 ,不同灌水量、施氮量和施磷量与产量的回归模型 ,并进行了主因素效应、单因素效应和交互作用分析。经模型寻优 ,求出了不同目标产量下的水、氮。Based on the experiment of the current rotary combination design of square regression of 3 factors with 5 levels, the regression model of effects of irrigation quota and the amount of N and P with corn yields under the conditions of irrigation on plastic film in Litong County of irrigated areas from Ningxia diverting Yellow River water in the arid region of the Northwest China was established. The main and single-factor effects and interactions of the model were studied.The optimum combination schemes of water with the N and P chemical fertilizers under different yields were obtained through the model.
