稻田温室气体排放研究综述

Review on Greenhouse Gases Emissions From Rice Paddies

甲烷和氧化亚氮是稻田的主要温室气体,对全球变暖起着重要的作用。为此,综述了水分管理、施肥方式、品种差异、农耕方式及土壤气候等因素对甲烷和氧化亚氮排放的影响。同时,从综合温室效应角度出发,提出选育适宜的品种、加强水分管理、合理施肥以及选择合适的耕作方式等措施,为发展生态农田系统提供参考。

Two major greenhouse gases,methane （CH4 ） and nitrous oxide （N20） ,play significant roles in global greenhouse effect. This paper reviewed the effects of irrigation ,fertilization, species differences ,farming practices, soil-climatic conditions and other factors on emissions of CH4 and N20 from rice fields. Considering the synthetic greenhouse effect, some measures of reducing greenhouse gas emission in rice fields were also put forward such as breeding suitable varieties, strengthening irrigation, rational fertilization, selecting appropriate farming methods, etc. This paper might provide some references for developing ecological farmland
