[目的]冬季种植紫云英翻压还田对促进稻田养分循环和提高氮素利用效率具有重要意义，本文重点研究了紫云英还田与氮肥配施对稻田温室气体排放的影响。[方法]盆栽试验条件下，设置紫云英与氮肥配施6个处理：不施肥（CK）；单施尿素（CF）；单施紫云英（MV）；1/4紫云英+3/4尿素（1/4 MV+3/4 CF）；1/2紫云英+1/2尿素（1/2 MV+1/2 CF）和3/4紫云英+1/4尿素（3/4 MV+...
稻田CH4 和N2O 的排放受水分、温度、施肥情况、有机质含量、pH 值、氧化还原电位( Eh) 等诸多环境环境因素的影响, 而水分和肥料是稻田温室气体排放的2 大驱动因子。综述了不同肥料施用对稻田CH4 和N2O 排放的影响, 并提出了相应的温室气体减排措施。
