摘要
水稻是重要的粮食作物,在我国农业中占有重要作用。稻田是温室气体的重要排放源之一,产生大量的二氧化碳(CO2)、甲烷(CH4)和氧化亚氮(N2O)等温室气体,这些温室气体已经严重威胁到人类生存并破坏环境。为阐明稻田内CO2、CH4及N2O的产生机制,从水分、施肥、耕作3个方面论述其对稻田温室气体产生及排放的影响,并根据温室效应等因素,综合性地提出了推行节水灌溉技术、选择合理的施肥方式、选择合理的耕作制度3种减排措施,对发展低碳农业和降低温室效应具有重要意义。
Rice is an important ration crop and plays an important role in China＇s agriculture.Paddy fields are one of the major sources of greenhouse gas emissions.They produce large amounts of greenhouse gases such as carbon dioxide（CO2）,methane（CH4）and nitrous oxide（N2 O）.These greenhouse gases have seriously threatened human survival and destroyed the environment.In order to elucidate the production mechanism of CO2,CH4 and N2 O in rice fields,the effects of water,fertilizer and tillage on the production and emission of greenhouse gases in paddy fields were discussed.According to the factors such as the greenhouse effect,3 kinds of emission reduction measures were put forward,including the implementation of water saving irrigation technology,the selection of rational fertilization methods and the selection of reasonable farming system.It is of great significance for developing low-carbon agriculture and reducing greenhouse effect.
