The soil is mainly sandy soil. The pH value of soil should be neutral or slightly alkaline, and it will not grow well in acidic soil.
Glycyrrhiza uralensis Fisch likes the ecological environment with abundant sunshine, little rainfall, hot summer, severe cold winter and large temperature difference between day and night, and has the characteristics of being fond of light, drought-resistant, heat-resistant, salt-resistant and cold-resistant. Four-year-old cultivated licorice is suitable as the best harvest time.
Northwest China, North China and Northeast China are all suitable for planting licorice, especially in Inner Mongolia and Xinjiang.
