甲烷是一种重要的温室气体,而农田是甲烷的重要排放源之一。因此,对农田甲烷排放进行研究具有重要的意义。该文从农业生态系统甲烷排放、土壤甲烷排放的影响因子,比如土壤含水量、土壤性质以及施用肥料的种类及肥料施用方法等方面综述了稻田甲烷的研究进展。探讨了缓解农田甲烷排放的管理措施,尤其是减缓稻田甲烷排放的措施。提出了未来开展稻田甲烷的研究方向,以期为进一步控制稻田甲烷排放提供一定参考。
Methane is an important greenhouse gas and farmland is one of the major sources of methane emissions. Therefore, it is of great significance to study methane emission from farmland. In this paper, the progress of research on methane in paddy fields is reviewed from the aspects of methane emission from agro-ecosystem, influencing factors of soil methane emission, such as soil moisture content, soil properties, types of fertilizers applied and fertilizer application methods. Discussed the management measures to alleviate methane emissions from farmland, especially the measures to mitigate the methane emission from paddy fields. Proposed the research direction of paddy field methane in the future, in order to provide some reference for further control of methane emission in paddy field.
