摘要： 为了建立环境协调型能源资源的供给体制，利用甜菜作为生物能源的原料，在其节能栽培技术方面进行了探索。以淡色火山灰土壤为供试土壤，播种采用直播方式，栽培采用简易耕作栽培技术，以移植和不耕起直播方式为对照。试验结果表明，含间接投入的2年平均分析结果，不耕起直播方式的能量收益是105 GJ/hm2，与现行的耕起移植方式112 GJ/hm2比较略低。但是，不耕起直播方式的产出与投入比为3.61，与耕起移植方式的产出与投入比3.01比较，呈现出高效率的趋势。同时，LCA方法评价结果表明，不耕起直播方式的CO2排出量是耕起移植方式的71%，环境负荷呈现出降低的趋势。

Abstract: In order to establish a supply system for energy resource coupled to the environment, the production technology of sugar beets was explored as a biological energy source. The low-humic andosolsas as the experimental soil, the panting method was direct planting, cultivation techniques was minimum tillage direct planting method, The control were conventional tillage transplant and no tillage direct planting.The results demonstrated that data revealed that the energy cost of no tillage and a direct planting method was 105 GJ/ha on average for two years, while that of the conventional tillage method was 112 GJ/ha per year. The ratio of output to input showed that the direct planting with no tillage was more efficient ( 3.61 ) than the conventional tillage ( 3.01 ). Moreover, the emission of CO2 into the atmosphere with no tillage and the direct planting was 71% of the conventional tillage planting technique. Therefore, direct planting without tillage reduces the impact on the environment.
