为研究添加辅料及微生物菌剂对牛粪高温好氧堆肥的影响,试验对不同处理牛粪的温度、p H值、GI值、含水率等指标进行了测定。结果表明:添加微生物菌剂后牛粪堆肥效果无明显差异,不添加可降低生产成本;若为提高堆肥效果而添加菌剂,可同时添加秸秆等辅料适当提高碳氮比有利于堆肥,且能解决畜牧业固体废弃物因焚烧和任意堆放污染环境的问题。各处理堆肥产物经实验室测定,其碳氮比(C/N)、含水率、氮、磷、钾总有效养分、有机质等指标均符合粪便无害化卫生标准和有机肥标准。
In order to study the effects of adding excipients and microbial inoculants on high temperature aerobic composting of cow dung, the indexes of temperature, p H value, GI value and water content of different manure dung were determined. The results showed that there was no significant difference in the composting effect of cattle manure after adding microbial inoculant, and no adding could reduce the production cost. Adding the fungus agent to improve the composting effect could increase the ratio of carbon to nitrogen in favor of composting at the same time, Solve the problem of animal husbandry and solid waste due to incineration and arbitrary deposition of the polluted environment. All the composting products were determined by the laboratory. The indexes of C / N, water content, total available nutrients of nitrogen, phosphorus and potassium, organic matter and so on were all accordant with the innocuous health standard and organic fertilizer standard.
