摘　　要：采用四元二次回归正交旋转组合设计，研究密度、氮肥、磷肥和钾肥4个栽培因子对泉豆7号产量的影响。结果表明：各试验因子对泉豆7号产量的影响大小顺序为氮肥＞磷肥＞钾肥＞密度。泉豆7号产量要获得超过2147.25 kg · hm ^-2的最佳农艺措施为：种植密度35.48万～37.82万株· hm ^-2，尿素79.02～88.71 kg · hm ^-2，钙镁磷肥438.75～484.50 kg · hm ^-2，氯化钾64.17～75.27 kg · hm ^-2。The effects of planting density and different NPK on the yield of Quandou 7 were studied by the design of orthogonal rotational regression combinatorial design . The results showed that the order of affecting yield of Quandou 7 was nitrogenous fertilizer＆gt; phosphate fertilizer＆gt; potassium fertilizer ＆gt; planting density . The optimal cultural methods for yields above 2 147.25 kg · hm2 was as followed ：planting density was （3.548-3.782） ＆#215; 105 plants ,nitrogenous fertilizer was 79.02-88.71 kg · hm ^-2 ,phosphate fertilizer was 438.75-484.5 kg · hm ^-2 and potassium fertilizer was 64.17-75.27 kg · hm ^-2 .
