It can be used as an excellent legume forage. Artificial cultivation of licorice has attractive business opportunities, and the market demand and export volume are increasing day by day, so it is still a godsend opportunity to develop licorice in the next few years. The main reasons for the rising price of licorice are as follows: first, there are a large amount of medicinal materials and 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. This fully proves that it is imperative to develop artificial cultivation of licorice. 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. Therefore, licorice is widely used in medicine, food, beverage, chemical industry, brewing and national defense construction and other industries. Planting management and harvesting technology growth habits: Gansu grassland wild in the desert, 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 newly reclaimed barren mountains and hills, and is preferably used for some large land contractors. Propagation methods: the seeds treated by scientific methods can be directly sown or nurtured and transplanting. Sowing time and transplanting: spring sowing: March-April; summer sowing: May-July; 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 40cm line spacing, plant spacing 15~18cm, deep 8cm, flat load in the ditch, cover with soil. Fertilization and soil preparation: urea 20 kg / mu, potash fertilizer 20 kg / mu, calcium superphosphate 50 kg / mu or compound fertilizer 50 kg / mu, and then apply low residual pesticides to kill underground insects. 30cm deep turning the ground, raking fine leveling, direct seeding to make a high border 60 cm wide, raising seedlings to make a 120 cm wide high border. Harvest and processing: licorice is put into medicine by root, which can be harvested before sprouting in October to December or spring, and can be planted in a large area. It can be detected manually after ploughing on a 50 tractor. After harvesting licorice, cut off the stems and branches, dig out the roots, clean the soil, chop off the Reed head, branches and fibrous roots, sun to half-dry, into small bundles, and then dry to sell. The quality is better if the skin is red and pink and the taste is sweet.
