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。 This article reviews the research progress of slow / controlled release fertilizers at home and abroad, the types of slow release fertilizer, existing problems and development directions. The production principle and production process of urea formaldehyde slow release fertilizer are introduced emphatically, which shows that urea formaldehyde slow release fertilizer has great potential for development. Urea Formaldehyde slow release fertilizer is helpful to relieve energy and environmental pressure. Slow-release fertilizer can effectively control the rate of nutrient release, extend the period of fertilizer, maximize fertilizer utilization, reduce nutrient loss, reduce environmental pollution and reduce social resource consumption, which is of great significance to the sustainable development of agriculture.
