摘　　要：在夏白菜营养液栽培的试验条件下 ,采用最优设计“4 16 -A”设计试验方案 ,建立回归方程 ,优选出配方浓度为 :Ca(NO3 ) 2 ·4H2 O :971mg/L、KNO3 :931mg/L、NH4H2 PO4:2 0 4mg/L、MgSO4·7H2 O :5 81mg/L。s: Under the conditions for the cultivation of summer cabbage in nutrient solution, by using the optimal design 416-A, the regression formula was established. The concentration of the selected nutrient solution composition was: Ca(NO 3) 2·4H 2O: 971mg/L, KNO 3: 931mg/L , NH 4H 2PO 4: 204mg/L,MgSO 4·7H 2O:581mg/L.
