为了精确估算稻田温室气体排放量并筛选合理的稻麦轮作模式，以长江下游沿江地区稻麦轮作系统为研究对象，基于品种特性和茬口安排，建立了2种“元麦-水稻”轮作模式——苏裸麦2号-移栽南粳46（A）、苏裸麦2号-直播南粳5055（B）和2种“小麦-水稻”轮作模式——扬麦29-移栽南粳5055（C）、扬麦29-直播南粳9108（D），采用静态箱-气相色谱法，于2021年11月—2022年10月进行CH4和N2O排放原位监测，对比分析不同轮作模式温室气体排放特征，通过计算全球增温潜势（GWP）、温室气体强度（GHGI）和净增温潜势（GWPnet）全面评价筛选环境友好、经济效益高的稻麦轮作模式。结果表明：不同轮作体系CH4、N2O排放以及温室效应差异显著，采用周年保护性耕作措施的 B 组合产量（比 A、C、...
