Licorice is the king of traditional Chinese medicine and has a wide range of uses. the underground part of licorice has the functions of clearing heat and detoxification, moistening the lung and relieving cough, relieving thirst and expectoration and so on. Most prescriptions of traditional Chinese medicine are inseparable from licorice, commonly known as "ten prescriptions and nine herbs".

In recent years, the price of licorice has been rising, mainly for the following reasons: first, a large amount of medicinal materials, a wide range of uses. Second, over the years of predatory mining, so that wild licorice in the stage of extinction. Third, licorice needs to grow for 2 ~ 3 years (including seedling growth period) before it can be harvested, and many people dare not plant it for fear of falling prices after planting. According to the statistics of the national customs, after China's accession to the WTO, the export volume of licorice has been increasing, and the export raw materials have been gradually transformed into semi-finished products. The increase in demand led to a continuous rise in prices.

II. Planting techniques

1. Growth habits. Gansu grassland, which is wild in desert and semi-desert steppe, is a strong alkali-resistant plant. Distributed in the continental climate zone, when its roots form Lignification, it is resistant to drought, flood, cold, light and cool and dry climate. The requirements of the soil are not strict, and the general soil can be planted. It is especially suitable for planting in newly reclaimed barren mountains and hills.

2. The method of reproduction. Direct sowing or seedling transplanting can be used for the seeds treated by scientific methods.

3. Sowing time and seedling transplanting. Spring sowing from March to April, summer sowing from May to July, and autumn sowing before White Dew. No matter what month the seedlings are raised, they can be transplanted to the field before and after the Spring Festival, with about 12000 seedlings per mu.

Transplanting: after the land is leveled, press 40 cm row spacing, plant spacing 15 cm 18 cm, depth 8 cm, flat planting in the ditch, cover with soil.

4. Fertilize and prepare the soil. Urea 20 kg / mu, potash fertilizer 20 kg / mu, calcium superphosphate 50 kg / mu or compound fertilizer 50 kg / mu can, and then apply low residual pesticides to kill underground insects. 30cm deep turning the ground, raking fine and leveling, direct seeding to make a high border 60 cm wide, raising seedlings to make a 120 cm wide high border.

5. Harvesting and processing licorice can be harvested in October to December or before sprouting in spring, and can be planted in a large area. It can be picked out manually after ploughing on a tractor. After the licorice is harvested, cut off the stems and branches, dig out the roots, remove the soil, chop off the Reed heads, branches, and fibrous roots, bask them in half-dry, wrap them in small bundles, and then dry them all. The quality is good with red skin and pink foot and sweet taste.
