[ Objective ] To explore the synergistic effects of Eisenia foetida and effective microorganisms (EM) on vermicomposting of pig manure and provide a new idea for rational and effective utilization and treatment of animal manure. [ Method] Use pig manure as medium, the experiment contained four groups which were CK group (blank control), EM group (inoculation with EM bacteria), EAM group (inoculation with earth-worm), and EAM and EM group (inoculation with EM bacteria and earth-worm), respectively. The experiment lasted for 60 d. On Day 0, 15, 30, 45 and 60, the pig manure was collected, and the content of total organic carbon (TOC), total Kjeldahl nitrogen (TKN),ammonium nitrogen ( NH4 ＋ -N), nitrite nitrogen ( NO3 - -N ) and water soluble carbon ( WSC ) was determined, respectively. [ Result ] On Day 60, in the EAM and EM treatment group, the TOC content and the WSC content was respectively decreased by 42.8％ and 58.9％; the TKN content was increased by 13.6％, the C／N ratio was reduced by 49.5％; and the nitrite nitrogen content was 96 times as high as that on Day 0. [ Conclusion] The synergy of earthworms and EM bacteria can accelerate the pig manure composting and improve the mineralization and stability of products.%[目的]研究蚯蚓与EM菌协同作用处理猪粪的效果,为合理有效地利用和处理畜禽粪便提供新思路.[方法]以猪粪为培养基,将试验分为4组,分别为空白(CK)组、接种EM菌(EM)组、接种蚯蚓(EAM)组以及同时接种蚯蚓和EM菌(EAM+EM)组,试验时间为60 d.分剐在0、15、30、45和60 d时收集猪粪样品,测定总有机碳(TOC)、全氮(TKN)、铵态氮和硝态氮含量.[结果]与对照组相比,60d后EAM+EM组产物中总有机碳降低了42.8%,全氮提高了13.6%,碳氮比下降了49.5%;铵态氮的转化率达98.1%,硝态氮增加了96倍,硝态氮与铵态氮的比值达到61;水溶性碳下降了58.9%.[结论]蚯蚓和EM菌的协同作用能够加快猪粪的腐熟,提高产物的矿化程度和稳定程度.
