Abstract

The invention relates to agriculture, in particular to the treatment of seeds before sowing, and can be used as a composition for coating cotton seeds. The aim of the invention is to improve the growth and development of cotton, increasing yields. The goal is achieved by the fact that a small amount of an alcohol-benzene extract, extracted from weathered brown coal, is additionally added to a known composition consisting of a 2% acetone solution of cellulose acetate, in the following ratio of components, May. %: alcohol-benzene extract 0,000025-0,000063; cellulose acetate 2-3; acetone - the rest. The proposed composition allows to improve the growth and development of plants and increase the yield by 3-5 c / ha. Table 3.

Description

The invention relates to agriculture, in particular to the treatment of seeds before sowing, and can be used as a composition for coating cotton seeds.

The aim of the invention is to improve the growth and development of cotton and increase yields.

Example 1. A carbon extract (EI) extract in an amount of 0.00014% is introduced into a 2% acetone solution of cellulose acetate. 0.3 kg of mechanically bared cotton seeds of variety 108-f with an average humidity of 6.3% are treated with this compound for 15 minutes at room temperature. After the treatment time has elapsed, the seeds are separated from the solution and dried in air for 20 minutes.

To determine the germination energy, seed germination, plant growth and development, and yield, the control and encapsulated seeds are sown in laboratory (Table 1 and 2) and field (Table 3) conditions, and in laboratory conditions, the treated seeds are sown in moistened sand.

Example 0.3 kg of mechanically bare cotton seeds of the 108-f variety with an average humidity of 6.3% are treated for 15 minutes at room temperature with a 3% acetone cellulose acetate solution containing 0.000025% Eu, Next example 1.

PRI me R 9. 0.3 kg of mechanically bare cotton seeds of the 108-f variety with an average humidity of 6.3% are treated for 15 minutes at room temperature with a 3% acetone solution of cellulose acetate containing 0.000013% Uh Next in example 1.

The data show that the optimal concentration of the alcohol-benzene extract in the encapsulating mixture is 0.000025-0.000063%, while achieving a high germination energy and germination (Table 1). A further increase or decrease in the concentration of alcohol-benzene. - ash extract does not lead to a sharp increase in seed germination energy and seed germination, therefore, for further research in laboratory and field conditions, the composition of the encapsulating mixture containing 0.000025% EI was selected.

As can be seen from the data of Tables 1 and 2, the use of EC as an additive to the known composition when encapsulating cotton seeds gives a positive effect at all stages of cotton development. So, the test of capsulated cotton seeds with the proposed composition gives an increase in germination energy by 8%, sprout length by 14%, root length by 18% compared to the known.

Seeds treated in Example 3 were field tested for three years. In Table 3, the mean values of four replications of 25 plants are given. From the data of table 3 it follows that the proposed composition for

encapsulation of bare seeds of cotton increases the number of bolls by 1.0–3.7 pieces, the weight of one bollard by 0.5–1.3 g, the yield of cotton raw from one plant by 9–10 g, the yield of raw cotton by 3 , 0-5.1 centners / ha

compared with the known composition.

Thus, the proposed composition for encapsulating bare cotton seeds, as compared with the known, significantly improves the growth and development of cotton,

which leads to an increase in the yield of raw cotton.
