为解决北方低温季节牛粪大量堆积问题,将筛选的糖、淀粉、蛋白质和纤维素分解菌株复配,优化出组合菌剂(T1+DF2+D2+D5+XB1+XA2),研究低温下优化组合菌剂对低温牛粪堆肥起温的影响。结果表明,在室外-20℃低温下,牛粪接种优化组合菌剂后物料迅速升温,48h达55.8℃,第4d达64.9℃,高温期维持8～9d,发酵周期缩短至15d,而未加菌和加常温发酵剂的对照则一直未进入高温期。说明添加低温复合发酵剂能使低温下牛粪堆体迅速升温,进入高温期,完成无害化,缩短发酵周期。
In order to solve the problem of massive accumulation of cow dung during the cold season in the northern part of China, the selected strains (T1 + DF2 + D2 + D5 + XB1 + XA2) were optimized by the combination of selected sugar, starch, protein and cellulose decomposing strains. Effect of Combination Bacteria on Temperature Rise of Low Temperature Cow Dung Composting. The results showed that the material was rapidly heated at a low temperature of -20 ℃ in cow dung, the temperature was 55.8 ℃ in 48h, 64.9 ℃ in 4d, 8 ~ 9d in high temperature and shorten the fermentation period to 15d Bacteria and control at room temperature starter has not yet entered the high temperature period. It shows that adding low-temperature compound starter can make the cow manure body rapidly warmer at low temperature, enter the high temperature period, complete harmless and shorten the fermentation period.
