摘    要:基于目前世界性的石油危机现状,分析了甘蔗在中国作为可再生生物质能源作物的必要性及可能性。甘蔗是C4作物,其光能转换效率、光合速率、单位面积生物产量显著高于其它作物,具有高净能比,适应性广、耐旱、产量潜力大。用甘蔗加工生产酒精,成本低。巴西利用甘蔗大规模生产能源酒精取代汽油已相当成功,因此认为甘蔗是中国最有潜力的生物能源作物,但是中国需要重视能源甘蔗品种的选育,加强甘蔗能源酒精生产工艺的研究与开发,开展相适应的酒精汽油燃料动力机械的研制。可以展望,利用甘蔗发展能源酒精生产具有广阔的前景。

关 键 词:甘蔗  能源酒精  潜力  品种选育

Abstract:Based on the present petroleum crisis in the world,the necessity and possibility for developing sugarcane as a sustainable reproduced energy crop in China were analyzed.As a C_4 plant,sugarcane is rather high in light inversion efficiency,photosynthetic rate and biomass productivity,which make it the highest in net energy rate.Sugarcane can be cultivated extensively especially in upland area because of its strong drought resistance,and its productivity potentials still high in China.The cost for ethanol production from sugarcane is economically practical,and Brazil has been very successful in utilizing sugarcane as an energy crop for ethanol production in replacement of petroleum in considerable extent.It is considered that sugarcane is a most promising bio-energy crop in China.However,China needs pay attention to the breeding of new energy cane varieties,developing technology for the processing of energy ethanol production for cane and corresponding automobiles based on ethanol energy.
Keywords:sugarcane(Saccharum officinarum L  )  energy ethanol  potential  breeding
