Planting method for ecological restoration type liquorice

Abstract

The invention discloses a planting method for ecological restoration type liquorice. The method comprises the processes of seed treatment, sowing, transplanting, fertilization and irrigation, insect pest prevention and digging. In the seed treatment process, seeds of Ningxia liquorice and Ural liquorice are collected; in the sowing process, the seeds are shallowly sown in July every year; in the transplanting process, rhizobium leguminosarum, fresh beneficial microbial population animal nature fertilizer in rumens of cattle and sheep and stains used as beneficial bacteria in the forage grass manufacturing ensilage process are transferred to the roots of liquorice seedlings; in the fertilization and irrigation process, organic farmyard manure is applied, and irrigation is performed five times every year; in the insect pest prevention process, a biological method is adopted for preventing insect pests; in the digging process, when basically-mature liquorice which grows for 3-5 years and reaches the medicinal commercial grade is dug, more than 80% of production stock plants are reserved, and at most 20% of medicinal commercial grade liquorice can be dug. By means of the method, management of the ecological environment and recovery of steppe ecology are achieved, sustainable development of liquorice land is ensured, maximization of economic and ecological benefits is achieved, and the planting method can be widely applied and popularized.

Description

Technical field: [0001] The invention belongs to plant cultivation techniques, in particular to a planting method of ecological restoration type licorice. Background technique: [0002] Licorice is a perennial herbaceous plant of the leguminous family, and its roots and rhizomes can be used as medicine, so it is an important medicinal plant. Since ancient times, my country has been the largest producer of licorice, among which the licorice produced in Ningxia, Inner Mongolia, Xinjiang and Gansu is the most famous. Glycyrrhiza licorice has excellent characteristics such as strong adaptability, drought resistance, cold resistance, and salt-alkali resistance. It has a well-developed root system and vigorous vitality. It is an important plant resource in the desert and semi-desert areas of western my country. and grassland resources, preventing land desertification and other aspects play an important role. [0003] Glycyrrhiza itself is a perennial herbal medicinal plant with a...

Problems solved by technology

However, due to the extensive use and over-exploitation of licorice, the lack of vegetation resources such as licorice has caused serious grassland desertification and the harsh climate environment of desertification.

At present, although the artificial planting of licorice is relatively successful, most of the licorice is excavated after 3 to 5 years with a large heavy plow with a depth of 50 to 80 cm. The obtained artificial planting of licorice has produced certain economic benefits, but it also caused The serious phenomenon of secondary desertification and the serious damage to the ecological environment have made it difficult to restore and protect the ecological grassland. The results of the closure of mountains and grazing prohibition for many years have not been effectively guaranteed.
