摘　　要：从肥料养分释放与作物吸收的"供—求"平衡关系出发,阐述了养分控释的在提高肥料利用率和减少面源污染中的意义;列举了养分控释的主要技术途径及其控释原理,并从控释材料来源、设备选型、控释效果等方面对各种技术途径进行了评述;在控释肥质量评价方面,说明了引入土壤因子的必要性和合理性,认为把"肥—土"作为一个整体来考虑,有利于控释肥的质量评价更客观、更合理.It is stated about the significance of nutrient controlled-release to improve fertilizer utilization ratio and decrease non-point pollution,the supply and demand balance relationship of fertilizer nutrient,the main technical ways and principle of nutrient controlled-release, the resources of controlled-release materials and the selection of machine.It is necessary to take soil into account and fertilizer soil as a unit in quality evaluation to make it more objective and reasonable one.
