LIU Ting-ting1,2,LI Yu-jun3,SHI Ming2,YAO Zheng-kui2,CHA Shi-lian2,ZHANG Fa-li2(1.College of Agriculture,Guizhou University,Guiyang,Guizhou 550025;2.Agricultural Institute of Qianxinan Prefecture,Xingyi,Guizhou 562400;3.Agricultural Bureau of Qianxinan Prefecture,Xingyi,Guizhou 562400,China)  
The orthogonal rotation regression design of 4 factors(seed quantity x_1,nitrogen x_2,phosphorus x_3and potassium x_4) was used in Fengyou 3,a wheat variety with high yield and resistance to establish the mathematical model between yield and 4 factors.That is,y=305.75+11.67x_2+14.5x_4-9.27083x2_2-8.02x2_4.The optimum combination cultivation technique for 314.63 kg/667m2 includes 6 kg/667m2 of seed quantity,22.5 kg/667m2of nitrogen and 30 kg/667m2 of potassium based on 2 000 kg/667m2 of farmyard manure.
