This invention discloses a tobacco stem-leaf angle regulator and its application. The regulator uses water as a solvent and further includes brassinolide and indoleacetic acid. It is applied after tobacco transplanting and during the budding stage, sprayed at the junction of the tobacco stem and leaf. The regulator provided by this invention, when sprayed during the tobacco seedling stage, can quickly and accurately control the tobacco stem-leaf angle, increasing it and helping the tobacco plant achieve an ideal plant shape. This solves the problem of an unreasonable plant shape caused by a small stem-leaf angle, ultimately improving the yield and quality of tobacco.
