摘要:

采用等温溶解平衡法研究了0 ℃、10 ℃和25 ℃下K2O-Ca-H2O体系的相平衡关系。用Origin软件绘制出相图,并根据相图分析了符合农业行业标准要求的液体型K-Ca体系水溶肥料配方范围,为含钙高钾大量元素水溶肥料、含钾高钙中量元素水溶肥料的制备提供了理论依据。

Abstract:

Phase equilibrium relationships of K2O-Ca-H2O system at the temperature of 0 ℃, 10 ℃ and 25 ℃ are studied by isothermal dissolution equilibrium method. With Origin software to draw the phase diagram, and formula scope of liquid K-Ca system water-soluble fertilizers which meet the requirements of agricultural industry standards is analyzed according to the phase diagram, which provides theoretical basis for preparation of water-soluble fertilizer containing calcium, high potassium and macroelements, and water-soluble fertilizer containing potassium, high calcium and medium elements.
