Planting method for ecological restoration type liquorice

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.
