METHOD FOR PRE-SOWING TREATMENT OF SEEDS OF LEGUMINOUS MEADOW GRASSES Russian patent published in 2021 - IPC A01C1/06 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. A method for pre-sowing treatment of seeds of leguminous meadow grasses is proposed, including the use of a silicon-containing preparation. For pre-sowing seed treatment, working aqueous sols of hydrothermal nanosilica with concentrations of 0.05-0.0005 wt% are prepared. on the basis of the initial aqueous sol of nanosilica of 2.5% concentration with a predominance of the size of its constituent particles 10-20 nm, which is obtained from hydrothermal solutions of the Mutnovskoye field in Kamchatka. The exposure time of the seeds in the sols of hydrothermal nanosilica prepared diluted with water is 120 minutes.

EFFECT: allows to increase the effectiveness of a stimulant of natural origin for plant development at the stage of seed germination.
