| 中文摘要 |
| 农田是重要的温室气体排放来源之一，其中蔬菜地的温室气体排放日益受到人们关注. 以北京市郊某温室种植的油麦菜地为研究对象，通过大棚试验，考察和比较了油麦菜地施用不同类型畜禽粪便堆肥产品的CH4、N2O和NH3排放特征及其影响因素. 结果表明，油麦菜地NRM、RM、CF处理的CH4排放系数分别为0.2%、0.027%、0.004%；N2O排放系数分别为0.18%、0.63%、0.74%；NH3排放系数分别为2.00%、3.98%、2.53%. CH4排放通量与土壤温度和地表湿度相关，N2O排放通量与土壤温度、地表温度和湿度相关，CH4、N2O和NH3排放通量均受土壤含水率影响，而温室中的气温不是影响CH4、N2O和NH3排放的主要因素. |
| 英文摘要 |
| Greenhouse gas (GHG) emission from vegetable land is of great concern recently because agriculture land is one of the major sources contributing to global GHG emission. In this study, an experiment of Lactuca sativa L. land applied with different animal manure composts was carried out in a greenhouse vegetable land located in the surburb of Beijing to monitor the emission of GHG (CH4 and N2O) and ammonia in situ, and to analyze the affecting factors of GHG and ammonia emission. Results showed that the emission factors (EFs) of CH4 from Treatment NRM, RM and CF were 0.2%, 0.027% and 0.004%, respectively,the EFs of N2O from these three treatments were 0.18%, 0.63% and 0.74%, respectively, and the EFs of ammonia were 2.00%, 3.98% and 2.53%, respectively. CH4 emission flux was significantly affected by soil temperature and humidity, while N2O emission flux was related to soil temperature, surface temperature and humidity. The emission fluxes of CH4, N2O and NH3 were significantly affected by soil moisture, but there was little relation between CH4, N2O and NH3 emissions and the ambient temperature in the greenhouse. |
