FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. Invention represents method of producing biologically active preparations increasing germination of seeds of crops and increasing their resistance to unfavorable conditions, involving extraction of vegetal raw materials with subsequent evaporation of extracts to resinous state, where biologically active preparation is obtained from vegetal raw materials, which grow in Southern Yakutia, extraction at following temperature conditions: 2-times short-term heating of extraction system to 60–70 °C every 20 hours, cooling and fermentation of extractive substances without effervescence.
EFFECT: invention allows to produce preparations of herbal raw materials, which grow in Southern Yakutia, having growth-stimulating and anti-stress activity.
