Description

Изобретение относится к сельскому хозяйству, в частности, к предпосевной обработке семян хлопчатника.The invention relates to agriculture, in particular, to pre-sowing treatment of cotton seeds.

Известен способ предпосевной обработки семян,· заключающийся в том, что перед замачиванием семена подвергают обработ- s ке в электрическом поле коронного разряда при напряженности поля 1—4 кВ/см и временем обработки 1 —10 с [1].There is a known method for pre-sowing seed treatment, · which consists in the fact that before soaking the seeds are treated in a corona discharge electric field at a field strength of 1-4 kV / cm and a treatment time of 1-10 s [1].

Недостатком этого способа является малая эффективность, требуется предварительная тепловая обработка и процесс является многостадийным.The disadvantage of this method is its low efficiency, preliminary heat treatment is required, and the process is multi-stage.

Цель изобретения — повышение всхожести и увеличение урожайности хлопка.The purpose of the invention is to increase germination and increase cotton yield.

Поставленная цель достигается тем, что одновременно с воздействием электрическо- 15 го поля коронного разряда осуществляют облучение семян ультрафиолетовым излучением с длиной волны в пределах 300— 500 нм.This goal is achieved by the fact that simultaneously with the influence of the electric field of the 15th corona discharge, seeds are irradiated with ultraviolet radiation with a wavelength in the range of 300-500 nm.

Способ осуществляется следующим об- ₂θ разом.The method is carried out as follows ₂ θ at a time.

Семена хлопчатника перед посевом пропускаются через разрядное пространство с напряженностью 1—5 кВ/см в течение 1—60 с, где одновременно облучаютсяBefore sowing, cotton seeds are passed through the discharge space with an intensity of 1–5 kV / cm for 1–60 s, where they are simultaneously irradiated

УФ-облучением в области 300—500 нм и при комнатной температуре и нормальном давлении. Обработанные таким образом семена сохраняются в черных бумажных мешках в течение 8—12 дней, после чего их засевают.UV irradiation in the region of 300-500 nm and at room temperature and normal pressure. Seeds processed in this way are stored in black paper bags for 8-12 days, after which they are sown.

Как показали результаты полевых испытаний, всхожесть при этом составила около 85%, вегетационный период сократился на 5 дней и урожайность повысилась на 5,1 ц/га.As shown by the results of field tests, the germination rate was about 85%, the growing season was reduced by 5 days and the yield increased by 5.1 c / ha.

Claims

(54) METHOD FOR PREPARING OF SEEDS The invention relates to agriculture, in particular, to pre-sowing cultivation of cotton seeds. There is a method of pre-sowing seed treatment, which means that before soaking the seeds are treated in a corona-type electric field with a field strength of 1-4 kV / cm and a processing time of 1 -10 s 1. The disadvantage of this method is low efficiency preheating is required and the process is multistep. The purpose of the invention is to increase the germination and increase the yield of cotton. This goal is achieved by the fact that, simultaneously with the action of an electric field of a corona discharge, the seeds are irradiated with ultraviolet radiation with a wavelength within 300-500 nm. The method is carried out as follows. Before sowing, cotton seeds are passed through a discharge space with a intensity of 1-5 kV / cm for 1-60 s, where they are simultaneously irradiated by a COTTON UV irradiation in the region of 300-500 nm and at room temperature and normal pressure. The seeds thus treated are stored in black paper boxes for 8-12 days, after which they are sown. As shown by the results of field trials, the germination rate was about 85%, the growing season was shortened by 5 days, and the yield increased by 5.1 q / ha. The method of pre-sowing treatment of cotton seeds by applying an electric field of corona discharge, characterized in that, in order to increase the germinability and increase the yield, simultaneously with the influence of the electric field of the corona discharge, the seeds are irradiated with ultraviolet radiation from a wavelength within 300 -500 nm.
