Features of agricultural technology of Ural licorice in the North-East of Kazakhstan

Abstract

The results of the introduction of Ural licorice (Glycyrrhiza uralensis Fisch) are presented. The article presents experimental data on the production of raw materials in the natural and climatic conditions of north-eastern Kazakhstan. The possibilities of seed and vegetative propagation of Ural licorice have been investigated in order to obtain plant raw materials. In the experiment, we used planting materials in the form of beans, seeds, and cuttings collected in the natural growing conditions of the Pavlodar region (floodplain and steppe landscapes). 10 variants of the experiment were laid, in which various planting materials and biochar were used as fertilizer. The results of the experiment allow us to conclude that the best results were obtained when propagating licorice from the Ural cuttings. The most productive way of obtaining raw materials was option 8, where cuttings of steppe samples were used and biochar was used as fertilizer. The technology of rejuvenation of old age natural massifs of licorice has been tested to stimulate vegetative propagation. Rejuvenation led to an increase in the number of clonal shoots at a distance of up to 2.5 m from the mother bush. The authors observed at a distance of more than 2.5 m from the mother bush, attenuation of the vegetative potential.
