摘　　要：稻田系统作为重要的碳库,对全球碳排放具有十分重要的影响。灌溉方式和生物质炭的施用是影响水稻生长发育和稻田“碳汇与碳排”的关键措施。本文重点阐述了稻田甲烷排放机制、稻田土壤碳汇机制以及干湿交替灌溉和生物质炭施用对稻田“碳汇与碳排”的调控作用和机制。同时,对研究过程中发现的问题进行讨论,并对今后的研究方向进行了展望,以期为实现水稻高产高效生产与固碳减排协同提供理论依据。The paddy field system serves as an important carbon sink and has a significant impact on global carbon emissions.Irrigation methods and biochar application are key measures that affect rice growth,and the“carbon sequestration and emission”in paddy fields.This paper focused on the mechanisms of methane emissions from paddy fields,the carbon sequestration mechanisms in paddy soil,as well as the regulatory role and mechanisms of alternate wetting and drying irrigation and biochar application in the“carbon sequestration and emission”in paddy fields.Furthermore,the paper discussed the issues discovered during the research process and pointed a future research direction,aiming to provide a theoretical basis for achieving high-yield and efficient rice production while reducing carbon emissions.
