SU912093A1 - Method of presowing treatment of seeds - Google Patents

Description

The invention relates to agriculture and can be used for presowing treatment of rice seeds.

A known method of pre-sowing treatment of seeds, including their processing in an electric field and then in a solution of micro and macro elements 1.

A method is also known for the pre-sowing treatment of seeds, which includes processing them with an alkaline solution with a polymer solution containing pre-chemicals, stimulators, micro-elements, antibiotics, etc. 2 J.

The disadvantages of the known methods are considerable complexity and not high enough efficiency.

The purpose of the HacTOJHuero invention is to increase yields, mainly rice.

The goal; is achieved by the fact that in a known method, which involves applying a polymer coating to seeds, before applying a coating on seeds with an electric field, an acacrylamide solution with a concentration of 15-20% is used as the polymer coating, and Corona discharge, electrostatic. or alternating current field of 1 to 5 kV / cm intensity and exposure time of 1-5 s. PRI me R. 10-15 days before eating, rice seeds are treated in an electric 4 corona field with a tension-floor of 1 to 5 kV / cm for. 1-5 s. Then a 15-20% aqueous solution of polyacrylamide is prepared, in which, and salen are placed, treated in an electric field. For a better deposition of the polymer on the seeds, they are thoroughly mixed, then removed from the solution, and dried.

On the basis of this treatment, a thin layer of polymer film is formed on the seeds. The deposition of polymer film on the seeds is carried out as on the day of the electrical treatment of the seeds,

20 and 1-2 dl. Before sowing.

. Seeds are sown in four, repeated with a deep seed dressing (.5-6. Cm). Biological yields are recorded by taking the sheaf material fourfold with each replicate.

.In tab. 1.data given biological. Yield on the proposed

30 way. Seeds before applying the polymer coating are treated in an electric field of a corona discharge. The effect of seed treatment with different & electrical fields of rice germination is given in table 2.

The data obtained indicate that when sowing seeds with deep seeding on salty soils

and when using the proposed method in which the seeds are initially subjected to electrotreatment and then polymerized, the yield increase is 48.2%, and the germination and weight of the seedling increase.

The proposed method of presowing treatment of seeds is simple and effective.
