Description

The technical field to which the invention belongs

The invention relates to the field of agriculture in order to obtain plant products, at the same time enriched with such vital elements as selenium and germanium.

State of the art

A known method of enrichment of vegetables and cereals with selenium, including the treatment of seeds or roots of plants with an aqueous solution of sodium selenite. The content of selenium is a range of concentrations between 0.4 and 40 mg / l, followed by sowing the seeds in the soil and growing under the influence of light with a wavelength in the range of 600-700 nm, obtained from fluorescent lamps with an intensity of 240 µmol / m ² s or light-correcting polyethylene films in natural light indoors. Or carrying out root treatment with a nutrient solution containing selenium in concentrations from 0.001 to 1 mg / l. When growing plants using this method, the content of selenium in lettuce leaves of the Gurman variety was 565.0 µg/kg of dry weight [1].

A known method of enrichment of garlic and root crops with selenium, including soaking the bulbs and root crops for 48 hours in a 1% solution of sodium selenate prepared in electroactivated water with a pH of 8.0 [2].

A method is known for enriching vegetables with selenium, which consists in treating vegetative plants with an aqueous solution of selenium salt with a selenium content in a range of concentrations between 1 g and 200 g of selenium per cubic meter of solution, characterized in that this solution, in addition to salt, contains a plant extract in a proportion of 0, 1-10% to increase the intake of selenium in plants, stimulate growth and protect the plant or an aqueous extract, which uses by-products of the food and pharmaceutical industries. When obtaining a plant extract, the pH, temperature and duration of extraction are adjusted depending on the nature of the plant material in order to achieve the completeness of the extraction. When using this method, the selenium content in garlic bulbs was 2500.0 µg/kg of dry matter [3].

A known method of enrichment with germanium, including three-time treatment of vegetative plants during the period of the beginning, middle and end of intensive leaf growth with germatranol, used at a concentration of 0.15%, dissolved in a 1% DMSO solution, at a dose of 100 ml of solution per 1 m ² plantings [4].

Published data on the enrichment of plant products during the growing season of plants simultaneously with selenium and germanium have not been found.

Disclosure of the essence of the invention

For the complex enrichment of garlic with selenium and germanium, it is necessary to treat garlic plants three times during the period of the beginning, middle and end of intensive leaf growth with potassium selenite, used at a concentration of 0.15% and germatranol at a concentration of 0.15%, dissolved in a 1% solution of dimethyl sulfoxide (DMSO), at a dose of 100 ml of solution per 1 m ^{2 of} plantings. The use of this method contributes to the accumulation of selenium in the garlic bulbs at a concentration of 6700.0+670.0 µg/kg and germanium 78.0+12.0 µg/kg.

Implementation of the invention

A method is proposed for the complex enrichment of garlic with germanium and selenium during plant ontogenesis, including simultaneous treatment of plants at the beginning, middle and end of intensive leaf growth with germatranol at a concentration of 0.15% and potassium selenite - 0.15%, dissolved in a 1% DMSO solution. used at a dose of 100 ml of solution per 1 m ² of planting area. The treatment is carried out on both sides of all leaves using a sprayer that provides a fine spray of liquid at a temperature of 20-25°C.

It has been proven that the addition of DMSO promotes better penetration of potassium selenite and germatranol into plant tissues, which ensures more efficient absorption of selenium and germanium by plants. This method allows to obtain garlic cloves, the content of selenium in which is 6700.0±670.0 μg/kg and germanium 78.0±12.0 μg/kg (table).

It is assumed that the consumption of garlic enriched with selenium and germanium will lead to a decrease in the deficiency of these elements in the human body, increase resistance to cardiovascular and oncological diseases, and also allow the creation of dietary supplements containing effective concentrations of these elements.
