摘　　要：采用不同粒度氯磷铵系复混肥料，以水为溶解介质，研究了粒度对养分释放特性的影响。结果表明，粒度能有效调节养分释放速率及重组比例。粒状复混肥在水中的养分释放量与溶解时间的关系可以用对数函数进行表征。复混肥中的磷、钾养分释放比氮素效应延迟。In a laboratory experiment with the compound fertilizer NH_4cl NH_4H_2PO_4 KCl, the rate ofnutrient release and the ratio of the three n utrie n ts in the process of release we re show n to beadjustable by its granule size.The amount of nutrients released from the granular fertilizer appcaredto be a logarithmic function of time and the release of P and was delayed compared with that of N.
