摘要
缓/控释肥料是21世纪肥料发展的重要方向,对维护中国粮食安全、提高肥料利用率,实现农业生产与生态协调发展、节本增效和节能减排等方面均具有十分重要的意义。本文在总结缓/控释肥定义、作用机制、研究现状的基础上,阐述了缓/控释肥在农业生产中的应用效果和在应用及推广中存在的问题,提出了相应的对策和建议,展望了缓/控释肥的发展前景,以期为缓/控释肥的研究提供理论依据。
The important direction of fertilizer development in the 21 st century is on slow/controlled release fertilizers which are of great significance to maintain China’s food security,improve the utilization rate of fertilizers,and realize the coordinated development of agricultural production and ecology.Meanwhile,slow/controlled release fertilizers can save cost and energy,and increase efficiency and reduce emissions.Based on the summary of the definition,action mechanism and research status of slow/controlled release fertilizers,we expounded the application effects of slow/controlled release fertilizers in agricultural production and the existing problems in their popularization and application.Then we put forward some corresponding countermeasures and suggestions.Finally,the development prospects of slow/controlled release fertilizers were discussed.The results will provide a theoretical basis for the study on slow/controlled release fertilizers.
