Propagation methods and cultivation Management of Glycyrrhiza uralensis
Propagation method: propagate with seeds, rhizomes and ramets. 1. It is suitable to select and prepare land with sandy soil and loose red loam, applying barnyard manure 2500kg, turning 40~50cm deeply in autumn, raking fine and leveling, making high ridge, ridge width 40~50cm, furrow width 30~35cm. 2. Seed propagation due to the hard and thick cortex of licorice seeds, it is not easy to emerge seedlings. If you grind the seeds with the same amount of broken glass and seeds for half an hour before sowing, the germination rate is about 85%, or 3 times the amount of seeds.

The seeds were propagated for 3-4 years, and the rhizomes and ramets were harvested for 2-3 years. It can be dug in late autumn and early winter and before sprouting in spring. The digger in autumn is the best, with high content of glycyrrhizic acid and strong quality. After the licorice is dug out, remove the soil, remove the stem base, branches, fibrous roots, cut into a section of appropriate length, sun to half-dry, into small bundles, and then dry to the whole.
