| 摘 要： | 试验采用四因素五水平二次通用旋转组合设计，研究玉米品种“农大108”优质高产栽培与密度及施肥量（NPK）之间的关系，获得了农大108籽粒产量形成的数学模型及农艺措施优化组合方案。结果表明：4项农艺措施对籽粒产量影响顺序为钾肥＞氮肥＞磷肥＞密度；在本试验条件下，农 大108籽 粒 产 量 要 达 到7000 kg·hm^－2以上，其优化农艺措施区间是：栽植密度5．90万～6．25万株· hm^－2，施尿素341．33～374．10 kg·hm^－2，施过磷酸钙460．58～554．85 kg·hm^－2，施硫酸钾234．23～279．23 kg·hm^－2。

| Abstract: | Four factors and 5 levels of a secondary general rotation design was applied to carry out an optimization experimentation for the maize cultivation.The relationships among the cultivation,crop yield,planting density and NPK fertilization were obtained for Nongda 108 with a mathematic model.The four agronomic factors that affected the grain yield were：potash 〉 nitrogenous fertilizer 〉 phosphate 〉 planting density.The optimized agronomic conditions included a planting density of 59 000-62 500 strains·hm^-2 ,and the fertilizations of urea at 341.33 -374.10 kg· hm^-2 ,calcium superphosphate at 460.58 - 554.85 kg · hm^-2 ,and potassium sulfate at 234.23 -279.23 kg·hm^-2 ,which resulted in a grain yield of more than 7 000 kg·hm^-2 . |
