The invention is intended for use in agriculture. The method comprises treating seeds with water-activated, wherein the seeds are soaked in the anolyte solution initially at pH 7.2, oxidation-reduction potential is 900-1100 mV and chlorine content of 0.03-0.05% for 0.5-3 hours, and then a catholyte solution having a pH of 6.9, oxidation-reduction potential (-300) - (-500) mV for 2-24 hours and dried to a state of flowability. The method allows to increase the germination of seeds and increase productivity.

DESCRIPTION OF THE INVENTION

The invention relates to agriculture and can be used for pre-treatment of seeds of all cultivated and cereal crops that require relatively small amounts of seed per unit area.

Among the wide variety of chemical and physical methods to improve seed sowing qualities closest to the claimed technical essence is a method for pre-processing the seeds of fodder beet (see. AS USSR N 1753974, A 01 C 1/00, 15.08.92 Bull. 30 N ). Adopted as a prototype. In this method, seeds are soaked in activated water and then dried to a state of flowability. Recommended in this method, the seed treatment is weakly acidic activated water (indicated only pH 3-3,5), resulting, apparently, the electrolyte based on natural mineralization in water, based on inhibition "on the surface of the seed microorganisms causing plant diseases". In other words, this method applies only to decontamination (dressing) of seeds before sowing is not intended to effect bio-stimulation.

The invention solves the problem of increasing the germination of seeds of cultivated crops and their productivity by improving the quality of seeds due to decontamination of pathogenic organisms and bio-stimulation processes of their growth and development.

This is achieved by a method for pre-sowing seed treatment, comprising treating the seeds with water-activated, according to the invention initially soaked seeds in the anolyte solution with the following parameters: pH 2-7, the oxidation-reduction potential (ORP) (900) - (1100) mV , the active chlorine content (p AK) 0.03-0.05%, with 0.5-3 hours exposure exposure depending upon the degree zasporennosti seed and crop species, and then - in the catholyte solution with pH parameters 6-9 ORP (-300) - (- 500) mV for 2-24 hours and dried to a state of flowability. Thus introduced two phases preplant seed treatment: pre-disinfection phase of the anolyte solution and the subsequent phase of biostimulation catholyte solution.

The method is as follows. Seeds are placed in permeable bags, immersed in acidic or neutral anolyte with parameters: pH 2-7, AFP (900) - (1100) mV HGA 0.03-0.05%, and incubated for 0.5-3 hours depending on the degree zasporennosti seed. The seeds are then transferred to another vessel with a catholyte solution having the parameters of pH 6-9, AFP (-300) - (- 500) mV, and incubated 2-24 hours in it. After the seeds are dried by any means to the state of the flowability provided immediate seeding or retained on the bags, without prosushivaya within 208 days prior to seeding. Used in the process and katolidny anolyte solution produced in diaphragm electrolyzers.

In the application of the proposed method of pre-processing of row crops seeds Modification changes in the growth and development of plants are stored in 2-3 months (shoots appear 2-3 days earlier, and advanced development persists during the growing season). Field germination is increased by 15-35%, yields increased by 10-30% depending on the culture and growth conditions.

The proposed method of pre-sowing seed treatment may be part of an overall system of cultivation of cultivated and cereal crops with foliar treatment plants catholyte solutions to the major phases of growth and development.

Example N 1. Seeds fodder beet, corn and sunflower first treated by immersion in the anolyte solution with the parameters: pH 2,7; ORP 1150 mV, the HGA 0.04 for 1 hour. Then the seeds were soaked in the catholyte solution with parameters: pH 9 and ORP -420 mV, for 22 hours. The seeds of the next day in the preliminary drying to a state of flowability. As a result, accounting acreage obtained the following results in comparison with the control (standard factory sowing seeds 1 class): sprouting plants that have passed pre-sowing treatment by the method described above, there were 1.5 days earlier than in maize, 2 days earlier and sunflower 2.5 days earlier in fodder beet; field germination of corn was higher by 32.7%, sunflower - by 53.4% ​​higher in fodder beet - 58.3% higher; the average height of the plants at 30 days of age was 19.9 cm in maize (control - 16.8 cm), sunflower - 13 cm (control - 11.5 cm) in fodder beet - 13 cm (control - 10.8 cm); Corn yield was higher than the control at 15%, sunflower - by 37.7%, fodder beet - 42.8%.

Example N 2. Seeds of millet treated by spraying particulate anolyte solution with the parameters: pH 3, 1000 ORP mV and the HGA 0.04%, at a dose of 40 L per 1 ton seeds. Then the seeds were soaked in the catholyte solution with parameters: pH 9, ORP -450 mV for 3 hours and then kept in bags until the next day of sowing. The results obtained in the experimental plantings in extremely dry summer, in comparison with the control sowing seeds, pesticides etched (Kolfugo super), as follows: seedlings in the experiment were 2.5 days earlier; Field germination experiment - 70% (control - 35%); tillering rate in the experiment - 3.6 (control - 2.2); the yield in the experiment - 44 kg / ha (control - 26,3 t / ha).

CLAIM

Preplant seed treatment method, comprising treating the seeds with water-activated, wherein the seeds are soaked first in the anolyte solution with pH 2-7, the redox potential is 900-1100 mV and chlorine content of 0.03-0.05% for 0, 5-3 hours, and then in the catholyte solution to pH 6-9, redox potential (-300) - (-500) mV for 2-24 hours and dried to a state of flowability.
