摘要：
Four different additives of Medical stone (MS), Zeolite (ZL), Bamboo biochar (BC), and Wood vinegar (WV) were investigated in pig manure composting. The four additives reduced the peak CH4 emission from 54% to 74%, while reduced N2O loss from 36% to 69%, compared with control (CK). WV and ZL showed better ability in N2O loss reduction, yet MS with the efficient inhibition both on CH4 and NH3 emissions. The bacterial community analysis indicated that bacterial diversity in the maturity phase was higher than that in the thermophilic phase, especially with treatments of ZL, BC and WV. The selected factors of pH, temperature, TOC and DOC could influence the thermophilic phase, while EC and TKN related closely with maturity phase in pig manure composting.
