具有吸水保水功能的缓释/控释肥料的研究现状与展望
首发时间:2006-07-03
摘要:具有吸水保水功能的缓释/控释肥料指的是将缓释/控释肥料技术与高吸水性树脂相结合,既可以实现对肥料的控制释放,又可以起到一定的吸水保墒作用。本文综述了具有吸水保水功能的缓释/控释肥料的国内外研究现状、制备方法以及缓释性能的测定,并分析了具有吸水保水功能的缓释/控释肥料目前存在的问题及发展趋势。

Prospects and Present Status of a Slow-release/Controlled-release Fertilizer with Superabsorbent and Water-retention
Abstract:The combination of the slow-release/controlled-release fertilizer technique and superabsorbent polymers can form a slow-release/ controlled-release fertilizer with superabsorbent and water-retention,which have a dual properties of water retention capacity and controlled release at the same time. This paper reviewed the present status, preparation and determining method of nutrient release of a slow-release/ controlled-release fertilizer with superabsorbent and water-retention. The problems and development trends of a slow-release/ controlled-release fertilizer with superabsorbent and water-retention were also analyzed.
Keywords: superabsorbent polymers,Slow-release fertilizer,controlled-release fertilizer
