摘要
该文就国内外缓/控释肥料研究进展、缓释肥种类、存在的问题和发展方向进行了综述。重点介绍了脲甲醛缓释肥料的生产原理、生产工艺,说明脲甲醛缓释肥料极具发展潜力,脲甲醛缓释肥料有利于缓解能源、环境压力。缓释肥料能有效地控制养分释放速度,延长肥效期,最大限度地提高肥料利用率,减少养分流失,降低环境污染、减少社会资源消耗,对农业可持续发展具有重要意义。
Slow/controlled release fertilizers （SRFs/CRFs） have been paid more at- tentions by the researchersin recent years. In this paper, the application effects and methods, types, current problem and development prospect of SRFs/CRFsboth at home and abroad were reviewed. The production principles and processes of urea- formaldehyde slow release fertilizers were introduced; and It is suggested that the urea-formaldehyde slow release fertilizers show great development to ease energy and environment pressure.
