Plant growth regulator and application thereof and method for regulating grape growth

The invention provides a plant growth regulator and application thereof and a method for regulating grape growth. The plant growth regulator at least comprises 6-BA and ethephon, wherein a mass ratio of 6-BA to ethephon is 1:(1-39). According to the invention, the activity of a mixture formed by compounding 6-BA and ethephon according to a certain ratio is improved compared with the activity of the single agent, and the 6-BA and the ethephon are simultaneously used for regulating grape growth according to the proportion in the application, so that the yield and the quality of the grapes can be greatly improved, and a huge commercial value is brought to fruit farmers for planting the grapes. 本发明提供一种植物生长调节剂及其用途和调节葡萄生长的方法，所述植物生长调节剂至少包括6-BA和乙烯利，所述6-BA和所述乙烯利的质量比为1：(1～39)。将6-BA和乙烯利按照一定比例复配后形成的混合剂的活性要比单独使用的活性提高，采用如本申请中比例将6-BA和乙烯利同时用于调节葡萄生长，能够极大的促进葡萄的产量和质量，从而为种植葡萄的果农带来巨大的商业价值。
