摘要
随着国际上对环境污染重视程度的提高,复合肥中的环保型添加剂已成为国内外研究的热点,尤其是以聚合物为主要材料的具有防结块和缓/控施肥作用的包裹剂逐渐占据了市场主导地位。本文阐述了复合肥结块的机理以及聚合物包膜缓/控释肥料的养分释放特征;对包裹剂的种类进行了归类;分析了国内外环保型聚合物防结块剂和缓释剂的应用及研究现状和存在的问题;并展望了聚合物环保型包裹剂的发展前景。
The research on coated antieaked and stow/controlled release compound fertilizer became hot in domestic and overseas with the increase in the importance of environmental pollution. Especially, the polymer coat agent gradually occupied the dominant position of market. The mechanism of compound fertilizer caking and slow/controlled release fertilizer was expounded, and the developing status and developing of polymer coated agent fertilizer at home and abroad were prospected.
