摘要
我国畜禽粪便堆肥过程中有关温室气体(CH4、N2O)和NH3排放的基础数据十分缺乏,难以满足我国畜禽粪便温室气体减排的需求.本研究以猪粪为研究对象,通过现场试验和原位观测,考察翻堆频率对猪粪条垛堆肥过程中温室气体和氨气排放的影响.结果表明,翻堆频率对猪粪条垛堆肥过程的温室气体(CH4、N2O)和氨气排放均具有显著影响,不仅提高了温室气体和氨气的排放,而且加大了氨气排放所占总氮损失的比例(对照组42.2%、试验组70.05%).与N2O相比,CH4是猪粪条垛堆肥过程中CO2排放当量的主要贡献者.
It is of great concern for greenhouse gas （GHG） reduction of animal manure management in Ghlna clue to me extreme tack of GHG emission data during animal manure composting. Therefore, the purpose of this study was to investigate the effects of turning frequency on the emission of GHG （ CYI4 , N20） and NH3 during swine manure windrow composting through on-site observation of a full scale test in Beijing. Results showed that the turning frequency had significant impacts on the emission of both GHG and ammonia, which did not only increase the emission of GHG and ammonia, but also increased the percentage of total nitrogen loss due to NH3 emission （42.2% at turning once a week and 70.05% at turning twice a week, respectively）. Compared with N20 emission, CH4 emission was the main contributor to Global Warming Potentials （GWPs）.
