摘　　要：本文综述了N肥和有机肥的种类、施用量、施用方式和施用时间对稻田CH4排放的影响,提出了减少稻田CH4排放的施肥策略,并指出了今后的研究重点:加强对稻田CH4排放机理的研究;针对以往研究中的不足,全面深入研究施肥对稻田CH4排放的影响;进一步研究稻田温室气体排放的交互作用。In this paper the effects of variety, application rate, application mode and time of nitrogen and organic fertilizers on methane emissions from rice fields were summarize, d, and the fertilization strategies for mitigating methane emissions from rice fields were suggested. The research ＂emphases in the future should focus on investigating the mechanism of methane emissions, conducting complete and further investigations on the effects of fertilization on methane emissions to overcome the shortcomings of previous studies, and investigating the interactions of greenhouse gases emissions from rice fields.
