Abstract: In order to extend seedling-raising duration and further improve sugar beet production, seedling spindling control measures experiment was carried out. Two spindling control practices, i. e. spraying plant growth regulator and root-cutting method were applied in seedbed. The results showed that spraying plant growth regulator and root-cutting method during seedling-raising stage of sugar beet could not only control over growth of seedlings, but also enhance stress tolerance after transplanting to the field. Spraying plant growth regulator combined with root-cutting method could improve seedling quality and increase tuber yield by 14.2% after transplanting to the field. Spindling control measures during seedling-raising stage make it possible to early sowing and early transplanting, thus provide a powerful technical support for low cost, high yield and high sugar content cultivation system.
