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。
The combination of the slow-release/controlled-release fertilizer technique and super-absorbent polymers can form slow-release/controlled-release fertilizer with super-absorbent and water-retention, which have dual properties of water retention capacity and controlled release at the same time. This paper reviews the present status, preparation and determining method of nutrient release of slow-release/controlled-release fertilizer with super-absorbent and water-retention. The problems and development trends of slow-release/controlled-release fertilizer with super-absorbent and water-retention are also analyzed.
