针对农村猪粪典型处理方式中的固体堆放管理,研究猪粪在冬季(2012年11月~2013年2月)固体堆放过程中NH_3、 N_2O和NO排放特征. 实验共设两个处理--无覆盖(non-covered,NC)和水稻秸秆覆盖(covered,C),堆放时间为73 d,期间进行了3次翻堆操作. 实验观测了3种含氮气体(NH_3、 N_2O和NO)的排放通量和堆体剖面N_2O浓度变化. 结果表明,猪粪固体堆放过程中NH_3、 N_2O和NO排放累积量(以N计)分别占初始TN的比例为2.1%~2.6%、 0.02%和~0.000 25%. 两个处理的含氮气体排放通量变化趋势基本一致,且有覆盖堆体的含氮气体的排放量略低于无覆盖堆体. 在堆放初期,NH_3排放量最先出现峰值,之后N_2O和NO排放开始增加...

Swine manure solid storage is a typical management in rural area of China. In order to investigate the characteristics of NH3, N2O and NO emissions during manure storage in winter (Nov., 2012 to Feb., 2013), two treatments were conducted: non-covered (NC) and covered (C) with straws, and each treatment had three times of pile-turning during the 73 days storage. The emission fluxes of three nitrogen gases (NH3, N2O and NO) were measured and the profile-N2O concentrations inside the swine pile profile and in the soil under the pile were also measured. The results indicated that 2.1%-2.6%, 0.02% ...
