近年来,国家鼓励发展缓释、控释肥料,然而究竟什么是缓释肥,什么是控释肥,哪些产品是缓释肥,哪些产品是控释肥,二者到底又有何不同,人们并不太清楚,这无疑会影响缓释、控释肥的开发、推广和应用。为此,本刊特邀专家对有关问题进行探讨。
In recent years, the state encourages the development of sustained release and controlled release fertilizers. However, what are controlled release fertilizers, what are controlled release fertilizers, which products are slow release fertilizers and which products are controlled release fertilizers? What is the difference between the two and people? It is not clear that this will undoubtedly affect the development, promotion and application of sustained release and controlled release fertilizers. To this end, the magazine invited experts to discuss the issue.
