| 摘 要： | 为评价不同养猪模式温室气体排放情况,对南京六合发酵床和传统水泥地面猪舍温室气体排放情况进行试验测定。通过测定猪舍内空气中CH4、CO2、N2O浓度,根据二氧化碳平衡法原理,计算不同猪舍的温室气体排放通量。结果表明:发酵床舍内CH4、CO2、N2O的平均含量分别是传统猪舍的61.2%、78.6%、125.0%;其舍内CH4平均排放通量要低于传统猪舍,是其63.6%,而N2O和CO2平均排放通量分别是传统猪舍的10倍和1.4倍;考虑到传统猪场猪粪堆肥和化粪池后续管理过程中的温室气体排放,试验期间发酵床养猪模式每天每头猪排放的CO2当量的温室气体总量较传统养猪模式多26.3%,CO2是发酵床养猪过程中温室气体排放总量的主要贡献者,其次是N2O。 |

| Abstract: | Livestock production is an important contributor to greenhouse gas emissions. To evaluate greenhouse gas emissions of different pig raising models, an experiment was carried out in a bio-bed and a traditional cement floor barn in Liuhe, Nanjing. Concentrations of CH4, CO2 and N2O in the air of the barns were determined. The fluxes of greenhouse gas emissions from different barns were estimated based on carbon balance principle. The average CH4, CO2 and N2O concentrations in the bio-bed were 61.2%, 78.6% and 125.0% of those in the traditional barn, respectively. Compared with the traditional barn, the average flux of CH4 was 36% lower, but that of N2O and CO2 was 10 times and 1.4 times higher in the bio bed. Taking into consideration the traditional farm manure composting and swine lagoon in the process of follow-up management, the total greenhouse gas emissions as CO2 equivalent per day per pig from the bio-bed were 26.3% more than that in the traditional farm during the experiment. Carbon dioxide, followed by N2O, was the main contributor to the total greenhouse gas emissions in the bio-bed. |
