控释肥养分释放机理及其影响因素研究进展

Research advances on nutrients release mechanisms and influencing factors in controlled release fertilizers

阐述控释肥的定义与分类,养分释放过程、特征及内外影响因素,包括土壤环境(水分、温度、微生物、pH、质地),包膜材料,制造工艺和施肥方式等,最后对我国控释肥的研究重点作了展望、旨在为控释肥研发和应用提供参考.

In this paper,we elaborated the definition and classification of controlled release fertilizer,described the release processes and characteristics of nutrients,and discussed the internal and external factors including soil environment(moisture,temperature,microbes,pH,texture),coating materials,manufacturing processes and application modes,etc.Finally,the research emphases of controlled release fertilizers in China were prospected in this review,which aims to provide new insight into the development and application of controlled release fertilizer in the futher.
