为明确化肥减量配施有机肥对早稻田温室气体排放的影响,在长期定位施肥试验区采用密闭静态箱法采集温室气体,监测了常规施用化肥以及化肥减量配施鲜猪粪、沼液沼渣、猪粪堆肥、紫云英绿肥等不同施肥处理的早季稻田主要温室气体排放动态,探讨了不同施肥措施对稻田温室气体累积排放量、全球增温潜势(GWP)及排放强度(GHGI)的影响。结果表明:不同施肥措施下早稻田温室气体的排放存在明显的差异;与常规施肥相比,各化肥减量配施有机肥处理均促进了早稻田CH_4和CO_2的排放,而化肥减量配施鲜猪粪、猪粪堆肥处理的N_2O排放量分别降低了7.09%、4.89%。在早稻生长季,化肥减量配施有机肥虽引起了稻田GWP值的...

This study determined the effects of the combined use of nitrogen fertilizer and organic manure on the greenhouse gas emissions, cumulative emissions, emission intensity （GHGI）, and global warming potential （GWP） of early rice fields. The greenhouse gas produced through different treatments, including conventional chemical fertilizer and the combination of chemical fertilizer and organic manure[pig manure （PF）, biogas slurry （BF）, pig manure composting （DF）, and green manure （GF）], was collected by closed static chamber method in th...
