METHOD OF PRESOWING TREATMENT OF SEEDS OF AGRICULTURAL CROPS

摘要

FIELD: agriculture.;SUBSTANCE: method consists in seed treatment during five cycles. In the first cycle the seeds are treated with hot air with the temperature of 70°C. In the second and third cycles - with pulsed infrared radiation with a wavelength of 3.0-4.0 microns and the flux density of 5-10 kW/m². In the fourth cycle - with the infrared radiation with a wavelength of 1-1.4 microns and the flux density of 25-30 kW/m². In the fifth cycle - with the ultraviolet radiation with the wavelength of 0.25-0.3 microns. The interval of each cycle separately from each other is 1-2 sec. The speed of the temperature regime ranges from 1 to 5°C/sec.;EFFECT: invention enables to improve the quality parameters of seeds - germination capacity and germination power.;1 dwg, 3 tbl
