包膜肥料养分控释机理研究进展

Research advances on controlled-release mechanisms of nutrients in coated fertilizers

利用胶囊技术将易水溶性肥料包被起来是提高肥料利用率和减少施肥环境风险的一个重要手段 .在广泛收集国内外有关包膜肥料研究的基础上 ,探讨了包膜肥料养分控释的原理、过程和特征 ,概述了影响包膜肥料养分控释的因素和包膜肥料养分控释的数学模拟研究 。

Using encapsulation techniques to coat easily soluble fertilizers is an important way to improve fertilizer use efficiency while reduce environmental hazards. Based on a wide range of literature collection on coated fertilizer research,the theories,processes,and characters of nutrient controlled release from coated fertilizer were discussed,and the factors affecting nutrient controlled release and the mathematical simulations on it were reviewed. The main tendencies related to this research in China were also put forward.
