摘　　要：采用二次正交旋转组合设计,建立了甜高粱茎秆汁液发酵制酒精的酒精产量与CO(NH2)2的添加量、KH2PO4的添加量、MgSO4·7H2O的添加量和CaCl2的添加量的二次回归模型。用偏导数分析法得出了各无机盐添加量的最优组合,用降维分析法得出因素交互作用间的直观分析图。Quadratic regression equations between the yields of stalk juice of SNTZ No.2 sweet sorghum and application rates of CO（NH2）2, KH2PO4, MgSO4-7H2O, CaCl2 were established using orthogonal and rotational combination designs. The optimum ratios were got by differential coefficient and the intuitionistic analysis of the factors＇ interaction were got by cutting dimensions.
