稻田氨挥发及控制技术研究进展

Advances in Ammonia Volatilization in Paddy-field and Its Control Technology

我国南方稻田氮素损失严重,其中氨挥发损失在南方稻田中占有很高的比重。综述了稻田氨挥发的现状与规律,损失途径与机理,对控制氨挥发的农田施肥管理措施进行了探讨,为实现现代农业高产、构建高效的技术体系、保障农业环境安全提供科学依据。

The problem of nitrogen loss in paddy-field is serious, especially the ammonia volatilization losses account for a high proportion in the south of China. In order to provide a theoretical basis for high yield and ＇efficient technology system and agri-environmental safety of modern agricuhure, the status quo, rules, loss way and mechanism of ammonia volatilization in paddy-field were summarized, and the measures for controlling ammonia volatilization by fertilization and management in paddy-field were also discussed.
