摘　　要：以相图理论为依据,对青海某硫酸盐亚型盐湖日晒后的硫酸盐混盐和钾盐混盐加入适量芒硝,在15℃条件制取高品质的软钾镁矾即硫酸钾镁肥进行了相图分析和理论计算,给出了制取硫酸钾镁肥理想的配料比和加水量。The paper introduced the analysis and calculation on the phase diagram of the five elements water and salt system （ 15℃ ） in producing process of SPM fertilizer from the mixed crystallization salts which is added appropriate Na2SO4 in the sulfate salt subtype salt lake in Qinghai, based on the theory of metastable phase diagram of Na ^＋ ,K^＋ ,Mg^2＋//Cl^- ,SO4^2- - H2O system, the best content proportion of Na2SO4, the mixed crystallization salts and water was given.
