[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The purpose of this invention is to provide a vegetation bag for ecological restoration, which solves the problems existing in the prior art, promotes plant growth, reinforces the slope of the spoil heap, reduces soil erosion, and is inexpensive.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] This embodiment provides a vegetation bag for ecological restoration, such as... Figure 1 As shown, the method includes a vegetation bag body and an improved soil layer filled inside the vegetation bag body. The vegetation bag body is formed by sewing together an upper bag body 1 and a lower bag body 2. The upper bag body 1 has a grass seed layer 13 on the side near the lower bag body 2. The vegetation bag body is filled with an improved soil layer, and the grass seed layer 13 on the side of the upper bag body 1 near the lower bag body 2 means that the grass seed layer 13 adheres to the improved soil layer, enabling the grass seeds to grow rapidly. When the vegetation bags used for ecological restoration are laid on the spoil heap, they can serve as a carrier to promote rapid plant growth, while also having fertilization and water retention effects. This enables rapid ecological restoration of the spoil heap, stabilizes the spoil heap slope, and reduces the risk of soil erosion and shallow landslides. Furthermore, the vegetation bags used for ecological restoration are inexpensive, easy to produce, and simple to use. Preferably, the vegetation bags used for ecological restoration can be fixed to the spoil heap slope.

[0023] In a further preferred embodiment of this invention, the upper bag 1 also includes a wood pulp paper layer 12 and a coconut fiber mesh layer 11. The wood pulp paper layer 12 is used to fix and lay on the outside of the grass seed layer 13, and the coconut fiber mesh layer 11 is used to fix and lay on the outside of the wood pulp paper layer 12. The wood pulp paper layer 12 and the coconut fiber mesh layer 11 are fixedly laid on the outside of the grass seed layer 13, which can enhance the firmness of the planting bag body, while also facilitating plant germination and growth.

[0024] In a further preferred embodiment of this invention, the grass seed layer 13 has a substrate with multiple grooves 131 for filling with grass seeds. The grooves 131 are evenly distributed on the substrate. Sowing plant seeds such as bermudagrass and ryegrass into the grooves 131 evenly distributed on the substrate ensures uniform seed distribution.

[0025] In a further preferred embodiment of this invention, the substrate is made of wood pulp paper, which facilitates plant rooting.

[0026] In this embodiment, it is further preferred that the lower bag 2 is made of non-woven geotextile. Non-woven geotextile has advantages such as breathability, filtration, heat insulation, and waterproofness, which can ensure the smooth growth of plants.

[0027] In a further preferred embodiment of this invention, the improved soil layer is composed of a soil conditioner and spoil heap soil. The soil conditioner is a mixture of polyacrylamide, sodium polyacrylate, biochar, and animal manure in a specific ratio. Animal manure contains abundant N, P, K, and organic matter, which can address the problem of low soil fertility. Biochar has abundant pores and a large specific surface area, resulting in strong nutrient adsorption capacity. This effectively improves the problem of nutrient leaching in spoil heap soil, increases soil fertility retention, increases site oxygen content, enhances microbial activity, increases soil cation exchange capacity, reduces the impact of toxic and harmful substances on plants, and accelerates soil material and energy cycling. Polyacrylamide and sodium polyacrylate effectively enhance the site's water retention capacity, retaining valuable water resources for plant growth.
