FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, to development of plant growth stimulants for pre-sowing treatment of spring wheat seeds. Complex preparation for pre-sowing treatment of spring wheat seeds by semi-dry method includes potassium or sodium humate, beer yeast autolysate, calcium bentonite, gibberellic acid salts and brassinolide. Complex preparation is a bentonite-humate complex in the form of an aqueous suspension containing said components in the following concentration: gibberellins (gibberellic acid salts) – 35–45 mg/l, humate – 8–12 g/l, calcium bentonite – 35–45 g/l, beer yeast autolysate – 10–14 g/l, brassinolide – 250–350 mg/l.

EFFECT: invention increases stimulating capacity of preparations for pre-sowing treatment of seeds with a semi-dry method, accelerates germination of spring wheat seeds and development of their seedlings.
