一、缓释控释肥料的特性近年来,缓释、控释肥料作为新型肥料越来越受到社会各界关注,它是通过物理、化学和生物的方法,采取新技术、新材料、新工艺设备生产的、具有使养分缓慢释放和调控释放功能的一类肥料。施用缓释、控释肥料是提高化肥利用率的有效方法。缓释肥料与控释肥料的特性有所不同:缓释肥料施入土壤后转化为对植物有效态养分的释放速度低于速溶肥料,具有缓效性或长效 First, the slow release of controlled release fertilizer characteristics In recent years, slow release, controlled release fertilizer as a new type of fertilizer more and more attention by the community, it is through physical, chemical and biological methods, to adopt new technologies, new materials, new process equipment Production, with a slow release of nutrients and regulation of release of a class of fertilizer. Application of slow release, controlled release fertilizer is an effective way to improve fertilizer utilization. The properties of slow-release and controlled-release fertilizers are different: slow-release fertilizer is applied to the soil and is converted to a slower release of plant-available nutrients than immediate-release fertilizer, with a slow-acting or long-
