不同微生物菌剂处理对鸡粪堆肥发酵的影响

Effects of Inoculating Different Microorganism Agents on Composting of Chicken Manure

选择3种混合菌剂进行了鸡粪堆肥发酵试验。研究表明,鸡粪堆肥通过接种微生物菌剂,可以明显提高堆肥初期的发酵温度,加快堆肥物料的水分挥发,改变鸡粪中的微生物数量,缩短堆肥发酵周期,促进堆肥快速腐熟,特别是接种菌剂1(乳酸菌、酵母菌、枯草芽孢杆菌、沼泽红假单孢菌混剂)效果最好,与对照相比,堆肥发酵初期温度提高,中期达到55℃以上,高温期持续8d,水分含量降低8%,细菌、放线菌数量明显降低。

The effects of 3 microorganism agents on composting of chicken manure were studied. The results showed that microorganism agents could obviously improve fermentation temperature during early period of composting, change the amount of the microorganism and accelerate dehydration of compost materials and the maturity of composting. The effect of No. 1 microorganism agents was the best. The temperature in the compost inoculated with microorganism agents of No. 1 arrived at 55 ℃, high temperature persisted 8 days; mois- ture content was decreased by 8%. The amount of alive bacteria and actinomycete were decreased.
