摘要
以不溶性含钾硅酸盐岩石与不同钙质原料(石灰石、磷石膏和磷石膏钙渣)制备硅钙钾肥,并以水和柠檬酸溶液为浸取液,采用硅钼蓝分光光度法于680 nm波长处测定硅钙钾肥中有效硅的溶出率。采用正交试验设计法探索了影响硅钙钾肥中有效硅溶出的相关因素,对硅钙钾肥的使用和推广具有一定的指导意义。
Silicon-calcium-potassium fertilizer is prepared from insoluble potassic silicate rock with different calcareous raw materials （ limestone , phosphogypsum or calcium slag of phosphogypsum ） , water and citric acid solution are used as extracting solution , the available silicon dissolution rate of silicon-calcium-potassium fertilizer is determined by silicomolybdic blue spectrophotometry at 680 nm wavelength .Orthogonal experimental design method is used to study related factors influencing available silicon dissolution rate of silicon-calcium-potassium fertilizer , having a certain guidance meaning for use and popularization of silicon-calcium-potassium fertilizer .
