摘要:
为了寻找适于燃料乙醇生产的甘薯品种,分别测定了4个甘薯品种——品种1、品种2、品种3、南薯88 (对照)生育期100 d、130 d和160 d的可发酵糖含量和乙醇发酵参数,并进行了比较分析. 结果表明,品种1和品种2的单位面积乙醇产量分别达4.79 t hm-2和4.83 t hm-2,均高于对照品种南薯88 (4.58 t hm-2);品种1和品种2生长到d 130时单位面积乙醇产出速度最快,分别为36.84 kg hm-2 d-1和37.13 kg hm-2 d-1,对照品种南薯88的乙醇产出速度为35.24 kg hm-2 d-1;生产1 t无水乙醇,使用不同甘薯品种的原料消耗量依次为品种1 (6.40 t)<品种2 (6.49 t)<品种3 (7.31 t)<南薯88 (9.17 t),发酵废渣排放量(按干重计)依次为品种1 (0.56 t )<品种3 (0.60 t)<品种2 (0.63 t)<南薯88 (0.64 t). 说明品种1可在甘薯燃料乙醇生产上推广应用,且生长130天时即可收获,以提高甘薯燃料乙醇生产的经济性. 图4 表1 参14
Abstract:
Four varieties of sweet potato at different growth stages in Sichuan, China, and their contents of fermentable sugar and ethanol fermentation parameters were investigated. The results indicated that the fuel ethanol yields of variety 1 and variety 2 were 4.79 t hm-2 and 4.83 t hm-2 , respectively, which were higher than that of Nanshu 88 (4.58 t hm-2). When variety 1 and variety 2 grew for 130 d, their ethanol productions were fastest with yields of 36.84 kg hm-2 d-1 and 37.13 kg hm-2 d-1 , respectively, while that of Nanshu 88 was 35.24 kg hm-2 d-1. To produce 1 ton of ethanol, the feedstock consumption amounts were found in an order as: variety 1 (6.40 t)<variety 2 (6.49 t)<variety 3 (7.31 t)<Nanshu 88 (9.17 t), and the residue discharge amounts (in dry basis) after ethanol fermentation were found in an order as: variety 1 (0.56 t )<variety 3 (0.60 t)<variety 2 (0.63 t)<Nanshu 88 (0.64 t), which indicated that variety 1 could be suitable for ethanol production in Sichuan and it could be harvested after growing for 130 d based on its economic view.
