摘　　要：介绍了一种测定控释氮肥溶出率的方法,并用该方法分别对尿素和11种控释氮肥样品 同时进行操作,比较尿素及11种控释氮肥溶出率的大小,从而筛选出好的控释氮肥品种。A method of determining the dissolving rate of controlled release nitrogen fertilizer (CRNF) was introduced, by which an urea and eleven samples of CRNF were manipulated respectively, and the dissolving rates of them were compared, thereby, the finer kinds of CRNF were screened out.

关 键 词：测定方法 应用 控释氮肥 溶出率 肥料利用率
