摘　　要：以甜高粱品种九甜粱1号和九甜杂1号为材料,采用简易固态发酵法,对其茎秆提取乙醇进行了实验。实验证明,甜高粱茎秆是提取乙醇极佳的生物质能源。九甜粱1号茎秆可提取50%vol粗乙醇9.26 t/hm2,折99.6%vol的无水乙醇3.96 t/hm2。九甜杂1号茎秆可提取50%vol粗乙醇8.76 t/hm2,折99.6%vol的无水乙醇3.75 t/hm2。单位面积甜高粱茎秆乙醇提取量明显高于单位面积玉米籽实的乙醇提取量。但不同的甜高粱品种茎秆乙醇的提取量有明显的差异,要科学的选用甜高粱品种。Experiments on ethanol production from stems of sweet sorghum Jiutianliang #1 and Jiutianza #1 using solid fermentation were reported here. The results showed that the sweet sorghum stem was a great source of bioenergy. We produced 9.26 tons and 8.76 tons of 50 %vol crude ethanol （3.96 tons and 3.75 tons of 99.6 %vol anhydrous ethanol） from each hectare of the Jiutianliang #1 and Jiutianza # 1 species, respectively. Ethanol production from sweet sorghum stems is significantly higher than that from corn seeds based on each unit area. In addition, ethanol production from sweet sorghum stems is significant different from species to species. Therefore, we should select the right sweet sorghum species for ethanol production.
