摘要: 研究不同微生物复合菌剂及添加比例对猪粪与木屑混合(鲜重比为鲜猪粪∶木屑9∶1)堆肥过程中NH3挥发的影响.结果表明,在堆肥过程中,NH3挥发主要产生在堆肥前期15 d的升温和高温期,添加3‰的微生物复合菌剂1、2和3对猪粪堆肥中NH3挥发都有一定的抑制作用,减轻氮素损失与堆肥恶臭,添加5‰复合菌剂1有显著抑制作用(P<0.05).

Abstract: This paper studied the effects of different mixed microbial agents on the NH3 emission during pig manure-sawdust (9∶1,fresh w/w) composting. The results showed that the NH3 emission was mainly occurred at the high temperature (>50 ℃) period during the early 15 days of composting. The addition of 3‰ mixed microbial agents 1,2 and 3 had a definite inhibitory effect on the NH3 emission,and the effect of 5‰ mixed microbial agent 1 was significant (P<0.05).
