摘　　要：以水稻秸秆为原料,严格控制发酵温度(37±1℃)的条件下,比较了以猪粪、鱼塘污泥,猪粪和鱼塘污泥(按质量1∶1)的混合物为接种物的产沼气效果。结果表明,猪粪与鱼塘污泥混合物为接种物的平均日产气量、累积产气量和甲烷含量最高(分别为100mL、3309mL和54.7%),鱼塘污泥的各项指标次之(分别为99mL、2974mL和53.2%),猪粪的各项指标最低(91mL、2456mL和52.5%)。以猪粪与污泥混合物为接种物的发酵料液TS、VS降低的程度最大(28.2%、21.7%),鱼塘污泥次之(19.2%、15.4%),猪粪最小(17.2%、13.9%)。添加氨水的各实验组指标大于不添加氨水的各对照组。Three types of inoeulums were used to produce biogas using crop stalks as raw material at strictly controlled temperature（37 ＋ 1℃）. The result showed that the highest average amount of biogas （per day） , the highest accumu-late amounts of biogas and the highest methane content were achieved while using the mixed inoculum （weight ratio of pig excrement and fish pond sludge： 1： 1） as inoculum （ 100 mL,3309 mL and 54, 7% ） to the fish pond sludge, these variables were 99 mL,2974 mL and 53.2% , and in the case of pig excrement, these variables were 91 mL,2456 mL and 52.5% . The TS and VS of fermentation broth of mixed inoculum declined mostly （28, 2% ,21, 7% ） , to the fish pond sludge, these variables were 19,2% , 15.4% , while the variables were 17.2% , 13.9% in the case of pig excrement. Adding ammonia water in experiment could markedly improve biogas production,
