在油菜的蕾薹期、初花期喷施一定浓度的植物生长调节剂萘乙酸、微量元素锶和硼的混合配方，可以促进植株的生长发育，增强油菜光合作用，提高油菜花蜜腺的泌蜜量；增加主花序有效长度、千粒重和角果数，降低分枝部位和菌核病的发病率，菜籽产量增产１２％以上，含油量增加４％以上；微量元素中锶含量增加最明显。 In rapeseed buds at the early flowering stage sprayed with a certain concentration of plant growth regulators naphthalene acetic acid, trace elements strontium and boron mixture formula can promote plant growth and development, enhance rape photosynthesis and improve nectar secretion of nectar ; Increase the effective length of main inflorescences, 1000-grain weight and pod number, reduce the incidence of branches and sclerotinia, rapeseed yield increased by 12% or more, oil content increased by 4% or more; strontium content in trace elements increased the most obvious.
