FIELD: chemistry.SUBSTANCE: invention relates to biochemistry. The invention involves steaming hay in a water condensate at temperature of up to 100°C and weight ratio of vegetable material to condensate of 1:11, adding trace elements and macro-elements in form of an aqueous solution of metal salts to obtain an enriched hay suspension, conducting high-temperature hydrolysis of the enriched hay suspension at temperature of 150-160°C and pressure of 4.5-6 atm for 40-90 min to obtain a concentrated hydrolysate, multiple recycling of the concentrated hydrolysate, wherein each recycling step involves loading a new portion of hay, water condensate and trace and macro-elements into the steaming unit and removing wastes from the concentrated hydrolysate. The mass of the reloaded hay, water condensate and trace and macro-elements should be equivalent to the mass of wastes. Upon achieving concentration of nutrients of more than 5% in the concentrated hydrolysate, a portion of the concentrated hydrolysate is fed for steaming at temperature of 60-120°C to obtain a concentrated product - the desired biologically active preparation, wherein an equivalent amount of the water condensate and trace and macro-elements is fed into the hay steaming unit.EFFECT: invention increases cucumber yield.4 cl, 3 tbl, 1 dwg, 3 ex |
