稻田温室气体减排材料及其减排机理研究进展OA

Rice is one of the important food crops globally.The greenhouse gases produced during rice production process mainly include methane(CH4)and nitrous oxide(N2O),which have significant impacts on global warming.Therefore,mitigating greenhouse gas emissions from paddy fields is crucial for alleviating global warming.Five types of mitigation materials,namely urease inhibitors,nitrification inhibitors,electron acceptor inhibitors,biochars,and microbial inoculants can effectively mitigate greenhouse gas emissions from paddy fields by modulating the structures of soil microbial communities and improving soil properties,and are currently the primary materials for mitigating greenhouse gas emissions from paddy fields.This paper reviewed the mitigation efficacies and mechanisms of four types of materials(nitrification inhibitors,electron acceptor inhibitors,biochars,and microbial inoculants)for CH4 and three types of materials(urease inhibitors,nitrification inhibitors,and biochars)for N2O,while analyzing their application limitations.Furthermore,it identified future study priorities of greenhouse gas mitigation materials,including multi-functional mitigation materials,soil adaptability,and research,development,and promotion of novel materials,aiming to provide a foundation for green and low-carbon rice production.
