摘　　要：运用4因素5水平二次正交回归旋转组合设计,对杂交杂交玉米"安单4号"产量与密度及N、P、K施用量间的关系进行研究,建立产量与各因素的数学模型:Y=808.41-5.97X1-1.07X2+1.07X3+16.91X4-35.34X12-12.69X22-26.24X32-17.42X42+10.56X1X2+9.24X1X3+11.12X1X4+1.18X2X3-16.95X2X4-9.52X3X4。并得出在安顺及相似生态条件下,"安单4号"产量≥600kg/667m2优化栽培措施为:密度3566～3634株/667m2,氮肥24.17～25.48kg/667m2,磷肥48.78～51.22kg/667m2,钾肥30.61～31.85kg/667m2。Four factors five levers qucdratic rotational regression combination design was used to study the relationship of yield , density and the application rate of N, P and K to hybrid maize Andan No.4. A mathematical model of the mail factors and yield was established： Y=808.41-5.97X1-1.07X2＋1.07X3＋16.91X4-35.34X1^2-12.69X2^2-26.24X3^2-17.42X4^2＋ 10.56X1X2＋9.24X1X3＋11.12X1X4＋1.18X2X3-16.95X2X4-9.52X3X4. The model was posed that the excellent scheme for the high-yield （more than 600 kg/667 m^2）were as follow： the density was 3 566-3 634 plants/667 m^2,N 24.17-25.48 kg/667 m^2, P2O5 48.78-51.22 kg/667 m^2, K2O 30.61-31.85 kg/667 m^2.
