摘要
采用“3 11—B”二次回归优化设计 ,以钼、锌、硼微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 :在施尿素 (4 5kg/hm2 )、过磷酸钙 (12 0kg/hm2 )、硫酸钾 (4 5kg/hm2 )的基础上 ,钼酸铵 2 .88kg/hm2 、硫酸锌 10 .5 2kg/hm2 、硼酸 4.5 5kg/hm2 ,此时产量为 15 42 .10kg/hm2 ,并对钼、锌。
Application 311-B twice regression D-the best design,mung beans were tested with Molybdenum,Zinc,Boron of microelement fertilizer as primary factor,found the best model of mung beans fertilizer.Applying the model,the amount of fertilizer of the maximum product was:on the base of carbamide (45 kg/hm 2),calcium superphosphate (120 kg/hm 2),potassium (45 kg/hm 2),applying ammonium molybdate (2.88 kg/hm 2),zinc sulphate (10.52 kg/hm 2),boracic acid (4.55 kg/hm 2),its product was 1 542.10 kg/hm 2.And make a concrete analysis for single factor effect and interaction of molybdenum,zinc,boron.
