Method of the update of fixed cured natural licorice root in arid desert area

Abstract

The invention discloses a method of the update of fixed cured natural licorice root in arid desert area. The method comprises the steps of 1, selection of update area; 2, selection of the implementation time of update project; 3, prognosis of the growing trend of licorice root, selection of reasonable cured parts; 4, backfill extension. The update method has the advantages that, in comparison with the old annular furrow update method, regulations are provided for the implementation time of the update project, construction in the windy season is prevented, the burying of curing holes by sand is prevented, the destruction of the favorable conditions of licorice root cured sprouting seedling is kept away; at the same time, the formation of new sand source due to human destabilization of soil is prevented, windy season is avoided, the wind erosion and the amount of wind carrying sand are subsided; the update location is selectively determined, the density of licorice is wisely controlled; the work amount of the method is reduced by 57% or above compared with the update of the annular groove, manpower and material resources are economized. The method of the update of fixed cured natural licorice root in arid desert area is simple and easy, quick and effective, and is very practical and operable.

Description

technical field [0001] The invention relates to the technical field of desert vegetation restoration in Xinjiang, in particular to a renewal method for fixed-point root removal of natural licorice in arid desert areas. Background technique [0002] Licorice, Fabaceae, Glycyrrhiza genus, perennial herb, with strong roots and rhizomes, is a tonic Chinese herbal medicine. Licorice mostly grows in arid and semi-arid desert grasslands, desert margins and loess hilly areas, and its roots and rhizomes are used for medicinal purposes. Licorice is drought-resistant, salt-alkali-resistant, and barren-resistant, and has the functions of windbreak, sand fixation, and water and soil maintenance. It is widely distributed in sandy areas in Xinjiang. However, due to its high medicinal value, wild licorice has been illegally dug and harvested on a large scale, and wild licorice resources in Xinjiang are showing a rapid decline, with a total area of ​​more than 2 million hectares in the earl...

Problems solved by technology

In recent years, due to the key public welfare forest management and protection projects implemented by the state, desert forest areas have been completely closed, and the downward trend of licorice has eased. However, once the wild plant resources are destroyed, the population recovery is very difficult.

At present, some scholars have studied the restoration technology of wild licorice, but most of them adopt the method of ring ditch restoration, and there is no clear regulation on the root cutting period of licorice restoration, which causes soil disturbance during the planting and regeneration of natural licorice. Large, time-consuming and labor-intensive, low update efficiency
