The invention relates to a degeneration haloxylon ammodendron forest brush stumping rejuvenation method. The degeneration haloxylon ammodendron forest brush stumping rejuvenation method aims at solving the problem that a desert haloxylon ammodendron forest is slow in natural rejuvenation and prone to being limited by natural conditions and influenced by manual interference, a brush stamping processing method which is simple and easy to operate is adopted, and the problems that the haloxylon ammodendron forest is degenerated and the forest form is early degenerated are solved. After brush stumping processing is carried out, the haloxylon ammodendrons are high in germinating capacity, exuberant in branch growing and less in disease and pest harm, and the forest stand quality is greatly improved. Compared with an existing rejuvenation technology of the desert haloxylon ammodendron forest, the degeneration haloxylon ammodendron forest brush stumping rejuvenation method is simple and practicable; compared with existing irrigation-free forestation, manual work seeding rejuvenation and enclosure rejuvenation of the haloxylon ammodendron forest, cost is low, the period is short, the high practicability and the high operability are achieved, and the healthy and stable development and the sustainable utilization of the desert haloxylon ammodendron forest can be effectively prompted.
