摘要
采用“311—A”二次回归最优设计 ,以氮、磷、钾为主要探讨因子 ,以产量为目标系数 ,对黄瓜高产施肥模型进行了研究 .根据模型得出最高产量施肥量为 :尿素 371 8kg/hm2 ,过磷酸钙 46 6 95kg/hm2 ,硫酸钾394 0 2kg/hm2 ,此时的产量为 5 8710kg/hm2 .
Application '311-A' twice regression D-the best design,cucumber were tested with N,P and K.Applying model of cucumber were studied.From the model,result of the amount of applying fertility of the highest output 1hm 2 land were applied with 371.8 kg carbamide;466.96 kg calcium superphosphate;394.02 kg potassium sulphate and the output of 58 710 kg.
