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 slow-release / controlled-release fertilizer with water-absorbing and water-holding function refers to the combination of slow-release / controlled-release fertilizer technology and super absorbent resin, which can not only achieve the controlled release of fertilizer but also play a role of absorbing moisture and preserving moisture. This review summarizes the current research, preparation methods and determination of sustained-release properties of sustained-release / controlled-release fertilizers with water-absorbing and water-retaining functions and analyzes the existing problems and development trends of slow release / controlled release fertilizers with water absorption and water retention .
