摘　　要：选取对小麦产量影响较大的施肥量、播期、密度等农艺措施,进行高产优质数学模型试验。结果表明,各因素影响小麦产量的顺序是:施氮量>播种期>密度>施磷量>施油渣量,并求出了在不同目标产量下的最优组合方案。Based on the experimental research,such agronimic measures as theamount of fertilization,sowing stage and sowing density affecting wheat yieldgreatly were selected to conduct the mathematical model of high-yielding andfine qualitz cultivation of winter wheat,whose results show that the sequencesof each factor affecting wheat yield are N fertilizer applied to>seeding stage>density>P fertilize added to>oil cake Put into.As a result,the optimum com-bined schemes under different yielding objectives are worked out.
