This invention discloses a sand-fixing method utilizing coppicing and sand burial of Haloxylon ammodendron, relating to the fields of windbreak, sand fixation, and vegetation restoration. Based on the natural growth angle of Haloxylon ammodendron branches, this invention applies coppicing and layering treatments to upright and inclined branches respectively. Inclined branches are laid flat against the ground and buried in sand, causing adventitious roots to sprout from the buried internodes and new suckers to grow upwards. These newly formed suckers are guided towards adjacent plants and buried perpendicular to the prevailing wind direction, creating a connected network structure between plants through their root systems and stolons. This invention classifies and treats branches according to their type. Coppicing upright branches reduces plant height and branch height, promoting tillering; sand burial of inclined branches induces adventitious roots, expands the water absorption area, lowers the center of gravity of branches and leaves, and increases ground cover, which is beneficial for improving the sand-fixing efficiency of vegetation, enhancing the water use efficiency of Haloxylon ammodendron, and promoting healthy shrub development.
