We used method of orthogonal rotation to study the effects of nitrogen level,phosphorus level,potassium level,planting density and row spacing on the yield of wheat yannong 19.The result shows that the planting density affects the yield of wheat Yannong19 significantly,followed by N level,row spacing and P level.With the yield target of 8250.0 kg·hm-2 for Yannong19,the corresponding application rates of N,P,K,density and row spacing were 203.5~209.6 kg·hm-2,88.1~92.0 kg·hm-2,107.7~112.3 kg·hm-2,280.62×104~287.04×104 hm-2 and 19.8~20.2 cm,respectively.With the yield target of 9000.0 kg·hm-2 for Yannong19,the corresponding application rates of N,P,K,density and row spacing were 203.3~209.2 kg·hm-2,87.7~92.3 kg·hm-2,105.8~114.2 kg·hm-2,287.88×104~297.12×104 hm-2,19.6~20.4 cm,respectively.
