摘　　要：传统的肥料利用率低,肥效期短,养分容易淋失、挥发和固定,缓控释肥料作为传统肥料的替代产品具有许多优点,能够大大提高肥料的利用率。因此,开发可控制养分释放速度,一次施用能满足作物各个生长阶段养分需要,低成本,生产工艺简单且对环境友好的缓控释肥是今后肥料领域研究的主攻方向之一。本文阐述了缓控释肥的定义、发展现状,总结了近年来我国缓控释肥领域的研究成果,分析了目前该领域存在的问题,指明了我国缓控释肥料今后的发展方向。Traditional fertilizer often has short effect period, and their nutrient was easy to be leached, volatilized and fixed. As the substitute of traditional fertilizer, slow/controlled released fertilizer has lots of advantage and can improve fertilizer utilization effficiently. Thus, developing slow and controlled released fertilizer with low cost, easy manufactory, single-dose application and friendly environment, especially coated fertilizer is the main direction in the future. The definition of slow/controlled released fertilizer was described, and current situation and problems of slow/controlled released fertilizer analyzed in the paper. The develop direction in future was also pointed out.
