摘要： 采用“311—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48.88㎏／hm2、过磷酸钙164.85㎏／hm2、硫酸钾60.43㎏／hm2，此时产量为1321.85㎏。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、千粒重的影响。

Abstract: 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 1hm2 land were applied with 48.88kg carbamide ; 164.85kg calcium superphosphate; 64.43kg potassium sulphate, the yield reached 1321.85kg/hm2. 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.
