Abstract

The invention relates to agriculture, namely to a method for storing seeds. The purpose of the invention is to increase the seed quality and yield. The method is carried out as follows: after drying to a moisture content 2-3% lower than conditioned, they are loaded into a container that is sealed. A vacuum with a vacuum of up to 100-200 mmHg is created in the vessel through a mounted device. to replace the gaseous medium of the interseed and intrasemenal spaces with the subsequent supply of waste nitrogen. By repeating the evacuation and supplying the gas, its concentration is adjusted to 99.0-99.9%. Under such storage conditions, the respiration rate of the seeds decreases and the sowing quality over. a long time is at the original level. 2 tab.

The invention relates to agriculture, namely to a method for storing seeds.

The purpose of the invention is to increase the sowing qualities and yield of seeds

PRI me R 1. Dried seeds to a moisture content that is 2-3% lower than conditioned, are loaded into a container and it is closed. Through, mounted device from the tank with the help of a vacuum pump air is pumped out to 100-200 mm Hg. to replace the gaseous medium of the interseed and nutracene spaces with the subsequent supply of nitrogen Nitrogen is supplied immediately upon reaching vacuum. If the vacuum does not reach the desired limit, the air exhaust is repeated. Bumming is necessary to remove air from the interseed and intra-seed spaces, since the oxygen of the air supports breathing of se1mn, while the supply of nutrients

substances, and this contributes to the reduction of sowing qualities.

Seed storage takes place practically in pure nitrogen of 99.9-99.99%. This method of storing dry seeds reduces the respiration rate and maintains the seed quality at the original level for a long time.

PRI mme R 2. Stored seeds of corn varieties Bukovinsky 3 TV with a moisture content of 11%. After 3 years of storage, the intensity of respiration (the amount of C02, allocated 100 g of absolutely dry seeds per day), laboratory and field germination and seed yield are determined.

Seeds stored in the air and in the CSG served as controls. created by purging consisting of 99.9% waste nitrogen and 0.1% oxygen. When stored according to the proposed method is carried out

mn Stronger plants will form from these seeds.

The examples given show that the growth rate of seeds stored according to the method proposed above is higher, the laboratory and field germination is higher in almost all cases, and therefore a higher yield of seeds is obtained, both from corn and sunflower seeds.

The use of the proposed method in relation to the well-known allows preserving the sowing qualities of the seeds, avoiding frequent transfers of genetic, insurance and other seed funds.

Formula and crop, A method of storing seeds, including drying, storing in a hermetic container and storing in a controlled gaseous environment, characterized in that, with the aim of increasing the sowing qualities of seeds and yields, A vacuum of 100–200 mm Hg is created by storing it in a container, and the storage is carried out in a gaseous medium with a nitrogen content of 99.0-99.9%.
