Assessment of Cultivation Method for Energy Beet Based on LCA Method

In order to establish a supply system for energy resource coupled with the environment, the production technology of sugar beets was explored as a biological energy source. The low-humic andosol as the experimental soil, the panting method was direct planting, and cultivation technique was minimum tillage direct planting method. The control was 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/hm2 on average for two years, while that of the conventional tillage method was 112 GJ/hm2 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.
