摘要： 为利用甜菜作为生物能源的原料，在其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，以耕起移植区和不耕起直播区为对照，针对不同耕作方式对土壤物理性质及甜菜生长的影响进行了研究。结果表明，不耕起直播区与简易耕直播区比较，土壤结构易紧密化，甜菜易产生侧根。但是，在出苗、生育期以及产量方面的差异不显著。不耕起直播区的根部收获量与现行的耕起移植区相比，减产2.5%~9.2%。对于碎土性较好的淡色火山灰土，耕翻与整地作业可以简略化或者免除，同直播方式进行组合同样可以获得较高的产量。

Abstract: In order to establish a supply system for energy resource coupled to the environment, the production technology of sugar beet 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, this study on the impact of different tillage methods on soil physical properties and sugar beet growth. The results demonstrated that, the soil structure of no tillage direct planting was easy to be closely, and the sugar beet more branching root compared with minimum tillage direct planting. But there were not significant differences on the emergence, growth stage and yield of sugar beet. The yield reduction of root of sugar beet was by 2.5%-9.2%. There was high yield, which involves a combination of no tillage and direct planting, in low-humic andosols with good soil crushing.
