Abstract

A METHOD FOR TREATING SEMPHEN SEEDS, including processing them with a film-forming composition, characterized in that, in order to increase the germination of seeds and the mechanical strength of the covering film, before processing the seeds, cyclone down from the cotton seeds that have been de-injected has been added to the film-forming composition.

Description

coa k)

The invention relates to agriculture and can be used in the preparation of cotton seeds for sowing.

A known method of treating cotton seeds by treating them with a composition containing film-forming polymers based on polyvinyl alcohol 1.

The disadvantage of this method is inelasticity and the low mechanical strength of the film former, which is easily removed from the surface of the seed during drying or mechanical action.

There is also known a method of treating cotton seeds 2-Z / O-nsh with a solution of Elulose 2 acetate.

However, the cellulose cellulose film located on the surface of cotton seeds reduces the absorption of moisture by the seeds and, due to its lack of orientation, has low mechanical strength, which can easily be removed from the surface of the seeds.

The purpose of the invention is to increase the germination of cotton seeds and the mechanical strength of the covering film.

This goal is achieved by adding a cyclone down from the cotton seed to the film-forming composition prior to seed treatment.

Cyclone cotton, down gives the film-forming polymer elasticity and mechanical strength and, playing the role of capillaries in the film-forming polymer, pulls water to other cotton seeds, which leads to an acceleration of seed germination. In addition, such a film is not destroyed by mechanical shocks to which seeds may be subjected as a result of filling them into containers and spills.

Example 1. 0.2 kg of mechanically bare cotton seeds with an average humidity of 8.5% are treated for 20 minutes at room temperature with a 2% acetone solution of cellulose acetate containing cyclone cotton fluff in an amount of 0.1 ° / o by weight cellulose acetate. After the treatment time has elapsed, the seeds are separated from the solution and dried in air for 30 minutes.

A part of the seeds is used to determine:; and moisture absorption, for which the control Hi .ie and the encapsulated seeds are kept at room temperature for 4 hours in distilled water, after; that; about the seeds are removed from the water, and rolled A. AioT on filter paper for udale; and; excessive water and whine.

To determine germination, seeds are sown under laboratory conditions in a moist soil. Every day, the soil is specially moistened by artificial rain.

Data on water absorption and laboratory germination are shown in the table.

For comparison, 0.2 kg of mechanically open cotton seeds with an average humidity of 8.5% are treated for 20 minutes at room temperature with a prototype 2% acetone cellulose acetate solution. After the treatment time has elapsed, the seeds are separated from the solution and dried in air for 30 minutes. 5 Example 2. 0.2 kg of mechanically bare cotton seeds with an average humidity of 8.5% are treated for 20 minutes at room temperature with a 2% aqueous solution of polyvinyl alcohol containing 0.1% of the weight of polyvinyl alcohol cyclone cotton fluff. After the treatment time has elapsed, the seeds are separated from the solution and dried in air for 120 minutes. Next in example 1.

For comparison, 0.2 kg of mechanically open cotton seeds with an average humidity of 8.5% are treated for 20 minutes at room temperature with a 2% aqueous solution of polyvinyl alcohol.

Example 3 .. 0.2 kg of mechanically bare cotton seeds with an average moisture content of 8.5% are treated for 20 minutes at room temperature with a 1% aqueous solution of carboxymethylcellulose containing O, cyclone cotton fluff based on the weight of carboxymethylcellulose. After a period of treatment, the seeds were separated from the solution and dried in air for 120 minutes. Next in example 1.

For comparison, 0.2 kg of mechanically bared cotton seeds with an average humidity of 8.5% are treated for 20 minutes at room temperature with a 1% aqueous solution of carboxymethylcellulose.

Every year, the enterprises of the Ministry of Agriculture and the Cotton Gin Industry of the cotton-growing 5 republics prepare for sowing more than 350 thousand tons of cotton sown seeds. A significant part of these seeds does not germinate due to mechanical damage to the seed membranes and the destruction of the core by various microorganisms penetrating through the damaged shell, which leads to a significant loss of seed, a decrease in germination of seeds and a decrease in cotton consumption.

From the data tabulated, it can be seen that the proposed method increases the germination of cotton seeds, accelerates the emergence of shoots and increases the mechanical strength of the covering film.

Using the proposed method

in agriculture, it significantly saves seeds when sown.

The proposed method does not require the use of expensive starting materials, is easy to implement and facilitates the disposal of industrial waste.
