摘　　要：利用正交旋转回归分析研究氮、磷、钾、种植密度和行距对强筋小麦烟农19产量的影响。结果表明,密度对烟农19产量影响最大,依次是施氮量、施钾量、行距和施磷量,烟农19产量≥8250.00kg·hm-2的氮、磷、钾、密度和行距为施氮量203.5～209.6kg·hm-2,施磷量88.1～92.0kg.hm-2,施钾量107.7～112.3kg·hm-2,基本苗280.62×104～287.04×104hm-2,行距19.8～20.2cm。烟农19产量≥9000.00kg.hm-2的氮、磷、钾、密度和行距为施氮量203.3～209.2kg·hm-2,施磷量87.7～92.3kg·hm-2,施钾量105.8～114.2g.hm-2,密度287.88×104～297.12×104hm-2,行距19.6～20.4cm。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 Yannongl 9 significantly, followed by N level, row spacing and P level. With the yield target of 8 250. 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 ×10^4- 287.04 ×10^4 hm^-2 and 19.8 -20. 2 cm, respectively. With the yield target of 9 000. 0 kg·hm^-2 for Yannongl9, 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 ×10^4- 297. 12×10^4hm^-2 ,19.6 -20. 4 cm,respectively.
