Licorice, also known as sweet grass root, is a perennial herb in Leguminosae, which is drought-resistant, cold-resistant, light-loving and salt-tolerant. Besides the roots of Glycyrrhiza uralensis Fisch, the stems and leaves of Glycyrrhiza uralensis Fisch also contain a variety of trace elements needed by animals, which are highly granular and can be used as feed for various herbivores. The harvested fibrous roots of licorice also have medicinal value, such as licorice. It can be washed, dried and ground into powder and used as an animal feed additive. It is said that licorice is full of treasures.

China is the only country that produces and exports licorice in the world, among which more than 30 countries and regions export licorice, and the annual demand in Japan alone reaches 6,543,800 tons. Moreover, in our country, among more than 2,000 kinds of herbs, licorice is the most commonly used herb, and there are always ten kinds of fragrant herbs, so it can't be said that there is no grass. The flat wood method increases the light absorption area of roots, thus increasing the growth rate of roots, increasing the yield of wild plants planted for 2 years and 3-4 years, and improving the medicinal properties. Therefore, the value of Glycyrrhiza uralensis Fisch using artificial flatgrass is much higher than that of wild plants. International and domestic mayor/market demand continues to increase, prices rise, and a large number of manual excavations lead to environmental degradation. The State Council has issued relevant documents for many times to put an end to artificial digging of wild licorice, and strict control activities have been carried out in the main producing areas, and artificial cultivation of licorice has become the mainstream.

It is not difficult to grow licorice. If the soil and water are suitable, it can be planted in a large area. It takes 2 ~ 3 years to harvest licorice when planting, and the yield per mu is about 1200 ~ 1600 kg. Excluding labor costs and planting costs, you can earn about 3000 ~ 7000 won per mu. Glycyrrhiza uralensis Fisch is a perennial leguminous plant. Root administration has antipyretic, emphysematous and synergistic pharmacological effects. A large number of commonly used Chinese herbal medicines are called "ten prescriptions and nine medicines" in the field of Chinese medicine, and are listed as one of Chinese herbal medicines by the state.
