[0025] Example 1

[0026] like Figure 1A sand-fixing vegetation net bag, wherein the sand-fixing vegetation net bag is a net bag with one end open and formed by connecting multiple layers of composite nets. Figure 2 As shown, the multi-layer composite net comprises a first paper layer 1, a plant seed and fertilizer mixed layer 2, a second paper layer 3 and a plastic net layer 4 which are arranged in sequence. The first paper layer 1, the plant seed and fertilizer mixed layer 2, the second paper layer 3 and the plastic net layer 4 are connected to form an integral structure by pressing and fixing, preferably by hot pressing, without the need for other fixing parts and adhesives.

[0027] In this embodiment, the sand-fixing vegetation net bag is formed by enclosing multiple layers of composite nets and connecting them by sewing. It is about 650 mm long and about 400 mm wide. The open end of the sand-fixing vegetation net bag is provided with a closing rope 5 for closure after filling with sand.

[0028] The plastic mesh layer 4 can be a mesh woven from PP950D flat wire and PE380D round wire, which is used to fix seeds and fertilizers in the early stage, and does not need to be fixed in the later stage when the grass and trees grow up, and will automatically degrade after 2-3 years. Degradable plastic wires can also be selected to weave the mesh, such as: polylactic acid (PLA), polyhydroxyalkanoate (PHA), polyhydroxyalkanoate (PHA), carbon dioxide copolymer (PPC) or copolymer of butylene adipate and butylene terephthalate (PBAT), etc.

[0029] The plant seed and fertilizer mixed layer is obtained by stirring and mixing plant seeds and fertilizers (such as long-acting slow-release fertilizers or soil conditioners).

[0030] The first paper layer and the second paper layer are both made of degradable paper materials, such as virgin wood pulp paper.
