摘要
综述了控释肥料(CRF)的释放机制与尿素的转化过程,通过尿素释放机制与转化过程总结了制备控释尿素的材料与方法,并阐述了其控释效应与保水、生物降解等方面能力,同时对其环境性能进行了讨论,最后展望了未来规模化制备控释尿素的前景并对制备方法提出了建议。
This paper reviews the release mechanism of controlled-release fertilizers(CRF)and the transformation process of urea,and summarizes the materials and methods for preparing controlled-release urea.The controlled-release urea's controlled-release effect and its abilities to retain water,biodegradation,etc.are expounded.The environmental performance of controlled-release urea is also described.The prospects for the commercial preparation of controlled-release urea are predicted,and some suggestions are given for the preparation methods in the future.
