Mn(Ⅱ)对猪粪好氧堆肥过程中氮转化及微生物群落的影响研究
Roles of Mn(Ⅱ)in the Transformation of Nitrogen and Structure of Microbial Community during Aerobic Composting of Swine Manure
摘要
Abstract
This study investigated the effects of Mn(Ⅱ)addition on nitrogen transformation during pig manure composting.Different levels of MnSO4(0％,0.25％,and 0.5％)were added to pig manure com-posting,designated as CK,0.25 Mn,and 0.5 Mn treatments,respectively,in a 35-day aerobic compos-ting experiment.The results demonstrated that the addition of Mn(Ⅱ)significantly extended the ther-mophilic phase,enhanced microbial activity and organic matter decomposition efficiency,and reduced the emissions of NH3-N and N2O_N.The Mn(Ⅱ)amendments effectively promoted nitrogen transformation and fixation,with the 0.5 Mn treatment notably increasing the nitrogen content in the final compost.Fur-thermore,the inclusion of Mn(Ⅱ)improved the microbial community structure during composting,partic-ularly by enriching nitrogen-transforming microbial populations,thereby optimizing the microbial ecologi-cal environment of the compost.Overall,Mn(Ⅱ)supplementation contributed to multiple aspects of process optimization,elevating the overall quality of the compost.关键词
