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 667mE.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 667mE,has been designed as：sowing on May 5,3200 plants per 667m2,and appling urea fertilizer 40kg per 667m2.
