摘要
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 。
The mechanism of the modifier calcium magnesium phosphate preventing general phosphate fertilizer from caking has been studied.The tests of adding 3%,5%,7%,10% into the general phosphate fertilizer have been done.It is concluded that 7% calcium magnesium in general fertilizer can prevent it from caking and the effective P 2O 5% is almost unchanged.
