摘要: 甲烷是重要的温室气体,其辐射增温效应是CO2的20~30倍。稻田是CH4的重要排放源之一。稻田CH4的排放是稻田CH4产生、氧化和传输综合作用的结果。影响稻田CH4释放的因素众多。本研究从水稻的农耕制度角度总结近年来关于稻田CH4排放的影响因素的研究,系统地归纳了水稻生物学特性、品种栽种方式、水肥管理等方面对CH4气体排放影响,同时从耕作角度提出了稻田CH4减排的技术措施。

Abstract: Methane (CH4) is recognized as an important greenhouse gas, which comes from vast quantity of ecologic plots, especially paddy fields. However, the global warming potential of CH4 is 25-30 times as much as that of carbon dioxide (CO2). Methane emission from paddy field is the result of a complex array of soil processes involving plant microbe interaction, such as CH4 production, CH4 oxidation and CH4 transportation and many factors influencing the CH4 release of paddy fields. Among them, farming practices is one of the most important factors. This paper reviewed the contribution of farmer practices on CH4 in production, oxidation and emission, and put forward strategies to mitigate methane emissions from rice cultivation.
