缓/控释肥料包衣工艺及其控释性能评价方法研究进展

摘要

肥料作为农作物生长所必须营养元素的重要来源,对其进行包衣不仅可以达到缓/控释、提高其养分利用率等效果,并且可以增强肥料颗粒的强度、降低运输损失.综述了缓/控释肥料的包衣工艺及其控释性能的评价方法,提出了在实际应用中存在的问题和对策,为未来缓/控释肥料包衣工艺和控释性能的研究奠定基础.%Fertilizer is an important source of necessary nutrient element for crop growth. Coated fertilizer can not only achieve the slow/controlled release and increase nutrient use efficiency but also enhance the strength of fertilizer particles and reduce transport losses. The coating technology and evaluation methods for slow-controlled release efficiency of slow/controlled release fertilizer were summarized. Furthermore,problems in practical application and corresponding solutions were introduced, which laid the foundation for the research of slow-controlled release efficiency of slow/controlled release fertilizer in the fu-ture.
