摘　　要：采用硅钼蓝分光光度法，在680nm波长下测定钾钙肥中有效硅的含量，硅量在0～0．5625mg／100mL符合朗伯一比尔定律，加标回收率在99．7％～100．2％之间，实验结果满意，克服了其他方法的不足。The available silicone in potassium- calcium fertilizer is determined by silicone -molybdenum blue spectrophotometry . With the measuring of wave length 680 nm, the Lambert -Beer law is obeyed in the range of silicone content 0～0. 5625 mg/100mL. The sensitivity of detectivity is high with the rate of recovery of 99. 7%～100.2% ,wich avoids the disadvantage from other methods.
