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.
