摘　　要：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 large accumulation of cow dung in northem cold season, sugar, starch, protein and cellulose decomposing bacteria were selected and mixed to the optimized combination （TI ＋DF2＋ D2＋D5＋XB1 ＋XA2）. The effect of optimized combination inocula of low temperature cow dung compost temperature raising at low temperature was researched. The results showed that at -20 ℃ low temperature, the temperature of cow clung which added optimum combination quickly raised, 48 h reached 55.8 ℃, fourth day reached 64.9 ℃, high temperature maintained 8-9 days, fermentation period reduced to 15 d, while controls that without adding bacteria and added normal temperature starter had not entered the high temperature stage, so adding low temperature compound starter could make cow dung temperature quickly raise, enter high temperature period, completing harmless and shorten fermentation period.
