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.

The invention discloses a graphene 13C isotope-based haloxylon ammodendron seedling marking method. The method comprises the following steps: carrying out double-peak pit soil preparation by taking a root of a haloxylon ammodendron seedling as a center; the double-peak pits sequentially comprise a first pit, a first peak, a second pit, a second peak and the earth surface from inside to outside by taking the root of the haloxylon ammodendron seedling as the center; a graphene 13C isotope water-soluble fertilizer is applied to a first pit of the double-peak pits; placing a carbon dioxide absorption device; laying a thin film to cover the double-peak pits, so that the first pit becomes a closed space; according to the method, photosynthesis of the haloxylon ammodendron seedlings is effectively isolated from carbon dioxide generated by respiration of the graphene water-soluble fertilizer and soil microorganisms, so that carbon dioxide with < 13 > C isotope released by respiration of the microorganisms is prevented from being absorbed by photosynthetic organs of plants, and a reliable solution is provided for marking and tracing the haloxylon ammodendron seedlings by adopting the graphene < 13 > C isotope.
