How to select and prepare the land with licorice
The rhizome of Glycyrrhiza uralensis has a strong germinating ability and extends horizontally under the surface to the surrounding of the old plant. One licorice can send out dozens of new plants in several years. Artificial cultivation, sowing for 3 years, new plants can be seen at a distance of 3 to 4 meters away from the mother plant. Its vertical rhizome can also take root, and the depth of the root system varies according to the soil quality and the depth of the groundwater table, generally within the range of 1 to 2 meters, sometimes up to more than 10 meters, with deep roots absorbing groundwater to adapt to arid environmental conditions.

Planting methods and technical requirements of licorice
The main results are as follows: 1. There are great differences in the yield and quality of licorice under different climate and soil conditions. Licorice has strong adaptability to temperature conditions, and water conditions play a decisive role in the yield of licorice. According to the author's research, in the area of temperate precipitation 300~500mm in China, the precipitation can basically meet the growth of Glycyrrhiza uralensis in general years, and it can be cultivated on the land without irrigation conditions. In order to obtain high quality transplanting seedlings, the seedling land should have irrigation conditions. In areas with annual precipitation below 200mm, in order to obtain high quality and high yield, there is not enough underground.

Cultivation of Liquoric Root and Technology of Grassland Reseeding
Licorrhiza uralensis is a wild medicinal and forage plant. According to its biological and ecological characteristics, agricultural technical measures can be adopted to break the dormancy period of seeds, improve germination rate, meet the needs of water and nutrition for the growth and development of licorice, and improve its biological yield. 1. Cultivation techniques of liquorice (1) seed treatment. The seed coat was broken by rice milling machine, and the germination rate could be increased from 30% to more than 80% if the seed was not broken twice. (2) Land selection and preparation before sowing. in sandy, sandy and beach land
