The invention relates to the technical field of application of plant growth regulators, and particularly discloses a saline-alkali soil rice growth regulation composition and application thereof. The saline-alkali soil rice growth regulation composition comprises abscisic acid, brassinolide, indolebutyric acid and gibberellic acid which serve as effective components, agriculturally acceptable auxiliaries are used, and different compositions are used in different periods to regulate and control the growth of saline-alkali soil rice. The different periods comprise: applying a seedling growth regulator capable of promoting roots and strengthening seedlings at the seedling stage of rice; applying a jointing stage growth regulator for promoting young panicle differentiation in the jointing stage of the rice; applying an earing-promoting filling type break period regulator in the break period of the rice; and applying an anti-premature senility full heading stage regulator in the full heading stage of the rice.
