为明确厢作免耕养鸭、养鱼模式对双季稻田CH4、N2O排放量及其增温潜势（GWP）和温室气体排放强度（GHGI）的影响,了解稻田厢作免耕养殖的温室气体排放情况,本研究设置厢作免耕养鸭（W-RD）、厢作免耕养鱼（W-RF）、厢作免耕（W-CK）、平作翻耕养鸭（F-RD）、平作翻耕养鱼（F-RF）和平作翻耕（F-CK）6个处理进行大田对比试验,采用密闭静态箱法收集CH4和N2O的排放量,探究双季早晚稻田CH4和N2O的累积排放量、GWP和GHGI。结果表明:早稻CH4累积排放量在分蘖末期-孕穗期阶段排放最多,晚稻CH4累积排放量主要集中在返青-分蘖末期阶段,相对于晚稻,早稻CH4排放量占双季稻总排放量的61.60%～77.00%。早稻和...

To clarify the impact of no-tillage rice integrated farming modes on methane(CH_4)and nitrous oxide(N_2O)emissions, as well as the global warming potential(GWP)and greenhouse gas intensity(GHGI), different farming modes were applied in this study, including two rice-animal coupling modes and two tillage methods, to provide a theoretical reference for greenhouse gas emissions from farming under no-tillage in paddy fields. Six treatments were used, including wide-ridge cultivation with no-tillage rice-duck farming, wide-ridge cultivation with no-...
