METHOD FOR PRESOWING TREATMENT OF SEEDS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2010 - IPC A01C1/00 

FIELD: agriculture.

SUBSTANCE: method consists in the fact that seeds are supplied to slope surface, treated with an efficient dose of radiation and discharged. Seeds on slope surface are aligned with their long side along with slope surface. Efficient dose of radiation is established by simultaneous variation of optical capacity of radiator and angle of slope surface inclination to horizon. Treated seeds are sown not later than 24 hours after treatment. Method is implemented by device comprising frame with slope surface and at least one laser radiator. Chutes are provided on slope surface of frame. Angle of chute opening is α = 100-130° and is selected depending on angle of natural slope of seeds. Radius of top rounding is R = (1.0-1.2) × h, where h - static value of treated seeds width. Laser radiators are fixed on slope surface and are aligned so that optical axis of each radiator is perpendicular to slope surface and passes through geometric axis of chute.

EFFECT: invention makes it possible to improve crop capacity by 20-70%.
