METHOD FOR PRE-SOWING TREATMENT OF SEEDS OF ANNUAL AGRICULTURAL CROPS Russian patent published in 2021 - IPC A01C1/06 

FIELD: agriculture.

SUBSTANCE: method for pre-sowing treatment of clover and amaranth seeds is proposed, which are treated with a working solution of hydrothermal nanosilicon with a concentration of 0.05-0.005 wt.% obtained by diluting the initial sol of hydrothermal nanosilicon with a concentration of 5.0% in the mineral water Sernovodskaya. The sol of hydrothermal nanosilicon obtained from the hydrothermal solutions of the Mutnovsky volcano with the polydispersity of its constituent nanoparticles with a predominance of 10-20 nm in size and sulfur-containing Sernovodskaya water containing (mg/l) are used: potassium (K) 6.6; sodium (Na) 85.5; magnesium (Mg) 34.2; calcium (Ca) 52.4; fluoride (F) 1; chloride (Cl) 115.8; sulfate (SO4) 242; bicarbonate (HCO3) 366.1; natural iodine (I) 0.6. The exposure time of the seeds in the prepared solution is 30-40 minutes.

EFFECT: invention allows increasing the germination energy and germinating capacity of plant seeds.
