摘　　要：通过常规施肥模式下磷、钾用量基础上的氮肥用量试验;氮、磷用量基础上的钾肥试验;氮、钾和密度的三个因素试验及优化施肥模式与常规施肥模式的对比研究,提出了优化施肥模式对提高氮肥肥效、增加玉米产量具有显著作用。Through the experiment on nitrogen fertilizer application amounts on the basis of applying phosphate and potash fertilizer, the experiment on potash fertilizer application amounts on the basis of applying nitrogen fertilizer and phosphate fertilizer and the three-factorial experiment on nitrogen, phosphorus and density under the conventional fertilization mode and the comparison research between the optimized fertilization mode and the conventional fertilization mode, we got the result that the optimized fertilization and increase the maize yield significantly.
