| 摘 要： | 采用恒温发酵培养试验,研究了5℃和25℃时分别接种纤维素酶(X)、枯草芽孢杆菌(K)和EM菌(E)及其组合对新鲜猪粪发酵中的全氮、铵态氮、有机质、p H及微生物数量的影响.结果表明,5℃条件下,猪粪中微生物生长受抑制,细菌、真菌、放线菌数量均明显低于25℃,发酵终期猪粪有机质含量为70%~83%,p H值为7.16~7.36;25℃条件时,发酵终期猪粪有机质含量降至61%~72%,p H值升至8.09~8.94.与对照相比较,25℃下添加微生物和纤维素酶的处理有机质含量降低了2.95%~7.70%(除了K和XE处理),C/N值降低了4.04%~37.59%(除了XK处理),p H值增加了1.7%~26.8%.在总的添加量一致的条件下,发酵剂组合KE、XE、XK、XKE对猪粪发酵的效果优于单一发酵剂的X、K、E处理.
