摘　　要：为确定甘蔗叶干法厌氧发酵的最佳工艺参数,选择堆沤方法、草粪质量比、发酵温度这3个关键因素进行正交试验,优化工艺参数。试验结果表明:甘蔗叶干法厌氧发酵最佳工艺条件为:自然堆沤、草粪质量比1、发酵温度38℃,验证最佳工艺条件下产气量为655.30 L。同时研究分析表明,猪粪对甘蔗叶干法厌氧发酵有较大影响,在猪粪量相对较少的情况下,提高发酵温度也能增加产气量;堆沤时添加绿秸灵和腐秆剂对甘蔗叶发酵没有效果。In order to determine the optimum technological parameters of dry anaerobic fermentation of sugarcane leaves,an orthogonal experiment was conducted with method of composting,grass-manure ratio and fermentation temperature as three key factors in the experiment.The maximum gas yield of 655.30 L was obtained with natural composting at optimum grass-manure ratio of 1 and optimum fermentation temperature of 38℃.The results also showed that pig manure had a great impact on the dry anaerobic fermentation of sugarcane leaves.When the amount of manure was relatively small,the increasing of the fermentation temperature could also improve the gas production.The adding of two agents,Green Straw Decomposition and Stalk Rot Agent,had no effect on fermentation of sugarcane leaves in composting.
