The invention relates to agriculture and food industry, namely to methods of enrichment of selenium sweet pepper types paprika and some types of vegetables are natural accumulators of selenium.

It is known that the trace element selenium enters the human body from the soil through plant products. The lack of selenium in the diet for a person associated with the weakening of the body against the effects of adverse environmental factors (industrial emission of radiation), the development of cardiac diseases and cancer (Gavrilov A.A., Gavrilova NS // Biology of life span. - M.: Nauka. - 1991. - 280 S.).

One of the methods to optimize the level of security of the population trace is the use for human consumption selenium enriched vegetable plants, in particular sweet pepper types paprika. Among vegetable plants peppers types paprika widely used by man as raw and canned, and dried in a solid form or in powder form.

The main ways of dressing vegetable plants selenium are:

1. soil salts of selenium together with fertilizers for vegetable plants [RF Patent №2218764 C2, A01N 59/02, A01N 61/00. A method of enrichment of selenium in vegetables. / Golubkina N.A., Konobeev NI, Pavlov L.V., Slepko GI, Yuriev the SUMMARY. The applicant and patentee VNIISSOK, will be held. Application: 2001110330/13, 18.04.2001; publ. 20.12.2003];

2. the method of increasing the selenium content in clover medicinal by depositing selenium salts below the root of the plants in the phase of beginning of flowering, followed by copious irrigation [Patent No. 2340152 C2, AS 21/00, A01N 59/02. The method of increasing the selenium content in clover medicinal. Application: 2007102416/13, 22.01.2007; publ. 10.12.2008];

3. steeping garlic bulbs, nodules of Stachys and topinambur within 48 hours in 1%solution of sodium selenate, cooked on electroactivated water with pH 8.0 [RF Patent №2189155, 23L 1/304, A01C 1/00. The way of dressing of garlic and root vegetables selenium / Golubkina N.A.; Sokolov AA; A. Sokolova and other Applicant and patentee VIIIFX, VNIISSOK, will be held. Application: No. 97105011/13, 01.04.1997; publ. 20.09.2002].

Each of these ways of dressing vegetable plants selenium has its advantages and its disadvantages. However, the first method of enrichment of vegetable plants selenium by adding salts of selenium together with fertilizer to the soil during transplanting due to the simplicity of the method and of low complexity has advantages over the other two. The second way of dressing vegetable plants selenium by making salt solution of selenium under the root of the plant in the phase of beginning of flowering in the selenium concentration of 0.5 to 4.1 mg/DM2soils with subsequent abundant floor the PTO water is ineffective, as most of the aqueous solution of salts of selenium misses on the treated plant, which reduces the efficiency of the process and can lead to contamination of soils undigested salts of selenium. The third way is the enrichment of selenium garlic bulbs and root vegetables by soaking the latter in a solution of salt of selenium on the basis of electroactivated water is the most time-consuming and costly. The disadvantages of this method include the need for specialized training environment, as well as maintain a specific pH environment, which results in a complicated way.

Closest to the claimed invention, the set of essential characteristics is a way of dressing vegetable plants selenium by adding salts of selenium together with fertilizer to the soil during transplanting.

The task, which is aimed by the invention, is to increase the efficiency of accumulation of selenium in the pepper fruit types paprika and reduce material and labor costs for the entire process.

This task is solved in that a method of enrichment of selenium sweet pepper types paprika includes the cultivation of pepper plants with the introduction of doses of mineral fertilizers, and the pepper is grown seedlings way in winter greenhouses, and as part of the enrichment plants selenium used in the comfort of prolonged granules APION-30 (Automatic Feed Osmotic Pump), contains being 0.036% of sodium selenate, which contribute under the root system of the plant when transplanting from pots into the ground. The method does not require additional hardware and does not require additional application of APIONIDAE during the growing season of plants, which dramatically reduces the process of production of marketable fruit with desired properties on the content of selenium, excludes overdose fertilizer plants and soil contamination.

In the proposed method the study was conducted in conditions of "Agrocomplex "Doskino" Avtozavodsky district, Nizhny Novgorod.

The concentration of selenium in fruits of sweet pepper varieties lighthouse and varieties Cascade was determined fluorometrically method after drying of pericardia at a temperature of 30°C to constant weight under laboratory conditions, and the content of biologically active substances using standard techniques in the MINISTRY of education of the Nizhny Novgorod state agricultural Academy and laboratory biochemical studies of the GSI research Institute of breeding and seed production of vegetable crops [Mamedov M.I.

It is revealed that the application of APIONIDAE significantly increases the content of biologically active substances, vitamin C, β-carotene, capsanthin, capsorubin and total carotenoids. The use of APIONIDAE with the addition of sodium selenate increases the levels of selenium, a natural antioxidant in the fruit 7.4-7.7 times compared with the standard (respectively cultivars Cascade and the lighthouse). In both cases, the research observed the reduction of nitrates to 80-120 mg/kg wet weight.

The increase in the content of ascorbic acid in the phase biological ripeness observed among varieties lighthouse - 38.2% and cultivar Cascade - 39.3% when using APIONIDAE. The use of sodium selenate leads to a slight decrease in the content of vitamin C.

The most important components of the pigment composition of varieties types of paprika are capsanthin and capsorubin that define the color n the Rosca, that is one of the main quality parameters in the International spice trade.

Thus there is sitespecifically response to the application of APIONIDAE. The use of APIONIDAE increases the total content of carotenoids: by 36.3% In grades lighthouse and 40.3% in grade Cascade. At the same time components of the carotenoid change differently. The variety lighthouse increases the content of β-carotene to 108.7%, capsanthin - 45%, and capsorubin reduced by 25.7%. The use of APIONIDAE containing selenate sodium, reduces the content of carotenoids by 34.8 and 24.1% compared with another option studies, but does not reduce these indicators compared to control.

A method of enrichment of selenium sweet pepper types of peppers, including plant growing pepper with the introduction of doses of mineral fertilizers, characterized in that the pepper is grown seedlings way in winter greenhouses, and as part of the enrichment plants selenium prolonged use granules APION-30, containing being 0.036% of sodium selenate, which contribute under the root system of the plant when transplanting from pots into the ground.
