摘要
研究接种不同微生物菌剂对牛粪堆肥发酵的影响,为筛选堆肥效果更好的优势菌种提供依据。通过选取3种代表性微生物菌剂进行牛粪堆肥试验,并对堆肥温度、含水率、pH值、C/N等进行指标分析,最后综合评判供试菌剂的性价比。试验结果表明,菌剂3应用于牛粪堆肥发酵的温度相对较高,最终含水率较低,pH值控制在适宜微生物生长的范围,C/N下降稳定,综合判定菌剂3的堆肥效果相对较好。
The effects of three microorganism agents on composting of cow manure were studied in the article. Then the temperature,water,pH and C/N of composting were surveyed and analysised. The results showed that microorganism agents of No. 3 was better, among the microorganism agents studied.
