摘　　要：为探究不同种类粪肥与黄腐酸配施对设施菜地N_(2)O及CO_(2)排放的影响,采用设施大棚小区试验,进行了两季上海青栽培,监测了不同肥料施加下蔬菜产量、土壤N_(2)O、CO_(2)排放通量和累积排放量及相关环境因子的变化。结果表明:土壤N_(2)O排放主要发生在施肥后的第2周,土壤CO_(2)排放主要发生在蔬菜生长的中后期;单施猪粪、鸡粪、羊粪处理在土壤N_(2)O、CO_(2)排放通量及累积排放量方面无显著差异,但粪肥配施黄腐酸增加了土壤N_(2)O、CO_(2)的排放;单施猪粪和羊粪处理的增产效果高于鸡粪处理,且粪肥配施黄腐酸增加了蔬菜产量。在环境因子方面,土壤含水率、p H、铵态氮、硝态氮是影响N_(2)O和CO_(2)排放的重要因素。综合考虑温室效应及蔬菜产量,羊粪配施黄腐酸的效果最佳。To investigate the effects of different manures in combination with fulvic acid on N_(2)O and CO_(2) emissions in greenhouse soil,two seasons of Chinese cabbage(Brassica chinensis L.)were grown in the greenhouse plots,and the emission fluxes and cumulative emissions of N_(2)O and CO_(2),related environmental factors and vegetable yields were determined.The results showed that N_(2)O emission mainly occurred in the second week after manure application,while CO_(2) emission mainly in the middle and late stages of vegetable growth.There were no significant differences in the emission fluxes and cumulative emissions of N_(2)O and CO_(2) among the treatments of single application of pig,chicken and sheep manures.But different manures in combination with fulvic acid increased the emissions of N_(2)O and CO_(2).The single application of pig manure or sheep manure was more effective in enhancing the vegetable yield than chicken manure,and additional application fulvic acid with manures increased the vegetable yield.The main factors influencing N_(2)O and CO_(2) emissions were the soil water content,pH,NH4+-N and NO3–-N.In conclusion,considering both greenhouse effect and vegetable yield,the sheep manure applied with fulvic acid performs best.
