探讨生产上广泛应用的高效植物生长调节剂对采种株甜菜的生长发育及各项指标的影响,为合理施用提供理论依据。结果证明:在采种甜菜从抽薹至开花前期,喷施芸苔素481调节剂,对种株增高、叶片增厚浓绿、茎秆增粗、分枝增多、种位降低、种球饱满均匀、优化品质、提高种子发芽率等影响较大,增产达12.5%～14.4%。
The effects of efficient plant growth regulators widely used in production on the growth and development of sugar beet varieties and their indexes were explored to provide a theoretical basis for rational application. The results showed that when sugar beet was planted from bolting to pre-flowering stage, brassinolide 481 was sprayed on the plant to increase the height of the plant, thicken the thick green leaves, thicken the stems, increase the branches, lower the seed position, full and uniform the bulbs, and optimize the quality , Increase seed germination rate and other larger impact, yield increased by 12.5% to 14.4%.
