对添加钙镁磷肥防止普钙结块的机理进行分析 ,在改性剂含量分别为 3%、 5 %、 7%、 10 %条件下进行试验 ,结果表明 :添加 7%的钙镁磷肥时既可有效防止磷肥结块 ,又可不改变磷肥中有效磷的含量
The mechanism of adding calcium, magnesium and phosphate to prevent the cacalcium caking was analyzed. The experiment was carried out under the conditions of modifier content of 3%, 5%, 7% and 10% respectively. The results showed that when adding 7% Phosphate fertilizer can effectively prevent agglomeration, but also does not change the content of available phosphorus in phosphate fertilizer
