METHOD FOR ENRICHING VEGETABLES WITH SELENIUM Russian patent published in 2003 - IPC

FIELD: agriculture. SUBSTANCE: the method deals with treating vegetating plants with aqueous solution of selenium salt at selenium content in concentrations ranged 1-200 g selenium/cu. m solution. Moreover, solution, except salt, contains vegetable extract in proportion of 0.1-10%. To obtain aqueous solution one should apply by-products of food and pharmaceutical industries, and at its obtaining it is necessary to regulate pH, temperature and duration of extraction depending upon the nature of plant material to achieve complete extraction. The present innovation enables to increase selenium inflow into plants, stimulate the growth and, also, fulfill plant protection. EFFECT: higher efficiency of enrichment. 2 cl, 3 ex, 2 tbl
