Seedling raising and transplanting techniques of Glycyrrhiza uralensis
The seedling base of licorice requires good irrigation conditions, flat plots, fertile land, and the size of the plot is not limited. It can also be developed in the courtyard. The sowing time can be from April to August every year, and 10 kg of treated seeds can be sown per mu. Sowing in drill, row spacing 15 cm, number of seedlings per mu 120,000 ~ 150,000. Transplant seedlings in spring in the second year and in spring in summer and autumn in the third year, with row spacing of 35 cm, groove depth of 8~10 cm and plant spacing of 8~10 cm. Flat planting method is adopted, and 15,000 ~ 20,000 seedlings are used per mu. After transplanting seedlings, autumn can be harvested, the general yield of 600~800 kg.
Because the flat planting method can enlarge the area of root absorption of light, the growth speed of root is accelerated, and the yield of artificial cultivation for two years is equivalent to that of wild 3~4 years, and the medicinal properties are also improved. Therefore, the value of licorice planted artificially is much greater than that of wild licorice.
