摘　　要：对某公司3种同养分(10-50-0)的磷酸一铵进行分析,探究其溶解后水不溶物沉降速率不同的原因。结果表明,磷酸一铵水不溶物在水溶液中沉降速率的快慢是由磷酸一铵及其水不溶物的杂质含量、颗粒大小、密度及组成结构等因素综合决定的。Three kinds of MAP with the same nutrient(10-50-0)of a company are analyzed to explore the reasons for the different sedimentation rates of water-insoluble substances after dissolution. The results show that the sedimentation rate of water-insoluble substances in MAP in aqueous solution is determined by the impurity content,particle size, density, and composition structure of MAP and its water-insoluble substances.
