摘　　要：采用“31 1—B”二次回归优化设计 ,以氮、磷、钾肥为主要探讨因子进行田间试验 ,建立了绿豆优化施肥模型 ,根据模型得最高产量施肥量为 :尿素 4 8 88kg/hm2 、过磷酸钙 1 6 4 85kg/hm2 、硫酸钾 6 0 4 3kg/hm2 ,此时产量为 1 32 1 85kg。并对氮、磷、钾单因素效应及交互作用作了具体剖析。同时分析了施肥对株高、茎粗。Application 311-B twice regression D- the best design,mung beans were tested with N、P and K Applying model of mung beans were studied From the model,result of the amount of applying fertilizer of the optimization 1 hm 2 land were applied with 48 88 kg carbamide; 164 85 kg calcium superphosphate; 64 43 kg potassium sulphate,the yield reached 1321 85 kg/hm 2 Efficiency of single fact and their interaction were analyzed,While effect of fertilizer on high of individual plant and stem-thick and weight of thousand grain were analyzed
