| 摘 要： | 包膜肥料是控制释放肥料中的一种．通过测定其释放养分的速度，可以评价它的缓释作用．测定释放养分速度的方法，一般有浸泡法和淋溶法两种，前者适用于释放速度慢的包膜肥料，而后者适用于释放速度较快的包膜肥料．并给出一些实测例子及评价．

| Abstract: | The membrane coating fertilizer is one sort of controlled release fertilizers. Its slow released efficiency is evaluated by determinating the rate of released nutrient.The method of determinating released nutrient rate consists of immersed and leached two kinds.The former is suitable for slow released rate coating fertilizer, and the later is suitable for comparative quick released one.Some examples of determination are given in this paper. |
