微生物菌剂对鸡粪堆肥理化指标和细菌群落组成的影响
Effects of microbial agents on physicochemical indicators and bacterial community during the aerobic composting process of chicken manure
摘要
Abstract
To investigate the effects of microbial agents on the maturation indicators and bacterial communities during the composting process of chicken manure,this study used chicken manure as the raw material and mushroom residue as the auxiliary material for aerobic composting.Two groups of experiments were set up:microbal agents treatment group and control group.The physicochemical indicators,seed germination index,and the structure and diversity of microbial communities during the composting process were compared.The results showed that at the end of the composting,the pH values for the control group and test treatment group were 8.37 and 8.70,respectively,the electrical conductivity values were 1.86 mS·cm-1 and 1.67 mS·cm-1,respectively,and the moisture content was 43.25%and 34.35%,respectively.Compared with the control group,test group reduced nitrogen loss rate by 28.65 percent points,and the seed germination index at the end of the composting was 115.18%,which was higher than the control group's 94.83%.High-throughput sequencing analysis revealed that the addition of microbial agents improved altered the composition of the composting bacterial communities,which contributed to the maturation of compost,and inhibited the growth of some conditional pathogens.The study demonstrates that the addition of microbial agents influenced the bacterial community structure of chicken manure compost,reduced nitrogen loss in the compost pile,and enhanced the maturity of the compost.关键词
