Abstract

The invention relates to agriculture and can be used for pre-sowing treatment of cotton seeds. The purpose of the invention is to increase the yield of cotton. The goal is achieved by treating the seeds of cotton before sowing with a polymorphic composition based on carboxymethylcellulose sodium salt, which additionally contains alkaline hydrolysis of the biomass of microorganisms and soapstock in the following ratio of components, wt.%: 3% Na-aqueous solution of Na-CMC 30-50; 20% solution of alkaline hydrolyzed microbial biomass 30-48.5; soap stock 0,5-1,5; water the rest. 1 tab.

Description

The invention relates to agriculture and can be used for pre-sowing treatment of cotton seeds.

The purpose of the invention is to increase the yield of cotton.

Example. Cotton seeds (variety Tashkent-1) are sown before sowing with a polymer composition that contains a 3% aqueous solution of Na-CMC, a 20% alkaline solution of microorganism biomass hydrolyzate and soap stock.

A solution of Na-CMC is obtained by dissolving the polymer in warm water. The alkaline biomass hydrolyzate is prepared by cooking the microbial biomass of 0.5N. NaOH or KOH solution for 2 h in a water bath at 98 ° C. An alkaline biomass hydrolyzate of 20% concentration is used for the polymer composition. Soap stock is a waste oil industry.

The formulation is prepared by mixing and thoroughly mixing all components, followed by neutralization with nitric acid to a pH of 7.0-7.2.

Seeds are coated with the prepared composition, which are rolled in a granulator for 1–5 minutes in a dry state. Then the polymer mixture is added to the granulator at the rate of 200 g per 1 kg of seeds and continue to roll them in another 20-30 minutes until the seeds are evenly moistened. After treatment, the seeds are dried with air at 24-28 ° C for 10 minutes. The treated seeds are sown in the field.

Untreated seeds and seeds coated with Na-CMC were used as controls. Compared with the prototype, the treatment of seeds with the proposed composition promotes the formation of a film resistant to mechanical effects on their surface. Seeds covered with such a film have a smooth surface, which reduces friction between the seeds, increases their flowability and leads to savings of seed material.

The table shows data on the effect of pre-sowing seed treatment on cotton yield.

The proposed composition improves the sowing qualities of seeds (germination) and increases the yield of cotton.
