摘　　要：为探讨芸豆合理施肥方案,应用三因素五水平二次正交旋转组合设计,研究氮、磷、钾配施对芸豆的产量效应,并建立氮、磷、钾施用量与芸豆产量关系的肥料效应函数模型。结果表明:三因素对芸豆产量影响的大小顺序为磷肥>氮肥>钾肥,且氮钾、磷钾的交互作用达到显著水平,通过方程模拟寻优得出,芸豆产量大于2 300kg.hm-2的施肥方案为N施用量63.8～94.0kg.hm-2,P2O5施用量118.5～152.8kg.hm-2,K2O施用量74.7～125.4kg.hm-2。N∶P2O5∶K2O的比例为1∶1.72∶1.27。In order to discuss rational fertilizer application scheme for kidney bean, the effect of the compound of N,P and K fertilizer on the yield of kidney bean was studied using the 3-factor-5-1evel quadratic rotational combination design. And the fertilizer response models were established between the N, P and K fertilizer and yield of kidney bean. Based on the model,the best fertilized plan was determined. The results indicated that the effects of N,P and K on the yield followed the order：P〉N〉K,and the interactive effects between N and K,P and K were significant. According to the model, the fertilized plans which the yield of kidney bean over 2 300 kg-hm-2 were 63.8-94.0 kg＇hmz N,118.5-152.8 kg-hm-2 P2O5 and 74.7-125.4 kg.hm2 KzO. The ratios of N . P2O5 ： Ks O was 1 ： 1.72 ：1.27.
