| 摘 要： | 试验采用正交设计,选4个栽培因素,即品种(A)、播期(B)、密度(C)、施肥种类和数量(D),均采用3个水平。试验结果表明:品种因素中,赤单202的最优组合是产量734.5kg/667m2,5月5日播种,密度3600株/667m2,追N肥30kg/667m2;赤早5号的最优组合是产量692.3kg/667m2,4月25日至5月10日播种,密度3600株/667m2,追N肥40kg//667m2;赤单661的最优组合是产量784.5kg//667m2,5月5日播种,密度3200株/667m2,追N肥40kg/667m2。

| Abstract: | A scheme of orthogonal test,which includes 4 factors and 3 levels,was designed.in which Maize Varieties,Sowing date,Density and fertilizer Varieties and Quantity.The results show that the technical formula for the Maize variety "Chidan 202" which reached above 734.5 kg per 667m2,has been designed as:sowing on May 5,3600 plants per 667m2,and appling urea fertilizer 30kg per 667m2.The technical formula for the Maize variety "Chizao 5" which reached above 692.3 kg per 667m2,has been designed as:sowing during April 25 to May10,3600 plants per 667m2,and appling urea fertilizer 40kg per 667m2.The technical formula for the Maize variety "Chidan 661" which reached above 784.5 kg per 667m2,has been designed as:sowing on May 5,3200 plants per 667m2,and appling urea fertilizer 40kg per 667m2. |
