Biological regulation compound for improving stress resistance of vegetables and application method of biological regulation compound

The invention provides a biological regulation compound for improving stress resistance of vegetables, which is prepared by the following steps: weighing 20-40g of indolebutyric acid and 25-35g of gibberellic acid, and sequentially adding into 1L of arthrobacter oxydans suspension. The biological regulation compound is used for soaking vegetable seeds and is sprayed in the growing period, so that the salt and alkali resistance of vegetables can be improved. The arthrobacter oxydans suspension not only can provide nutrients for vegetables and improve the yield of the vegetables, but also can further improve the salt and alkali resistance of the vegetables through the synergistic effect with indolebutyric acid and gibberellin. In addition, the arthrobacter oxydans suspension is compounded with indolebutyric acid and gibberellic acid, so that the problems of unstable performance and short storage time of the biological regulation compound after mixing can be solved. 本发明提供一种提高蔬菜抗逆性的生物调节复合物，所述生物调节复合物由以下步骤制成：称取吲哚丁酸
