Description

Technical Field

[0001] The utility model belongs to the technical field of sand prevention, sand fixation and vegetation restoration, and specifically relates to a long-acting greening vegetation net and a fixing structure thereof. Background Art

[0002] At present, artificial straw grids are basically used for sand control, sand fixation, sand prevention and dust prevention in China; the common way to restore vegetation is artificial afforestation. Artificial straw grids have high construction requirements for terrain such as sand dunes and hillsides, while artificial afforestation has a limited survival rate and slow effectiveness. In short, both methods have problems such as high manpower and material costs, low efficiency, and limited construction conditions. Utility Model Content

[0003] Based on the above technical defects, the purpose of the utility model is to provide a long-lasting greening vegetation net and a fixing structure thereof.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A long-lasting greening vegetation net is composed of a paper layer, a plant seed and fertilizer mixed layer, a non-woven fabric layer and a net layer which are arranged in sequence and fixedly connected. The net layer is a single-layer plastic net or a composite net layer. The composite net layer includes two layers of plastic nets and fertilizer bags inserted into the two layers of plastic nets.

[0006] With further optimization, the degradable paper layer, the plant seed and fertilizer mixed layer, the non-woven fabric layer and the mesh layer are connected into an integral structural layer by pressing and fixing.

[0007] According to a further optimization, the plastic mesh is a mesh woven from polyethylene or polypropylene wires.

[0008] Furthermore, the plastic mesh is a mesh woven from degradable plastic filaments.

[0009] Furthermore, the paper layer is preferably virgin wood pulp paper.

[0010] Furthermore, the plant seed and fertilizer mixed layer is a mixture obtained by mixing plant seeds and fertilizers, and the plant seeds include grass seeds and / or tree seeds.

[0011] Furthermore, a plurality of fertilizer bags are provided, and are arranged in parallel and at equal intervals between the two layers of plastic nets.

[0012] A long-term greening vegetation net fixing structure comprises a long-term greening vegetation net spread on a slope surface and a fixing component for fixing the long-term greening vegetation net; the paper layer of the long-term greening vegetation net is in contact with the slope surface, and the net layer is located at the upper part; the fixing component comprises an anchor pin and a thumbtack.

[0013] If the mesh layer is a composite mesh layer, the anchor pin head is fixed on one side of the fertilizer bag with its tail inserted into the slope; the thumbtack passes through the fertilizer bag from the upper center of the fertilizer bag and is inserted into the slope.

[0014] Beneficial effects of the utility model:

[0015] The utility model is laid on exposed sand land and sand dunes, which can not only suppress the flying of sand but also prevent soil erosion. After a certain period of artificial care, plants can grow in the net bags, and the vegetation can be restored in a short time to achieve greening.

[0016] The utility model product is suitable for different terrains and has the advantages of convenient construction and strong adaptability.

[0017] The use of degradable plastic nets can effectively fix the sand and soil to prevent it from flowing for a certain period of time, and then degrade naturally, which is environmentally friendly; no additional maintenance is required after the plants take root.

[0018] A fertilizer bag is provided to ensure long-term fertilizer effect and better improve the soil to promote plant growth; the fertilizer bag is inserted into the double-layer net and is not easy to fall off when snowing.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example 1

[0025] like Figure 1 The long-lasting green vegetation net shown is composed of a paper layer 1, a plant seed and fertilizer mixed layer 2, a non-woven fabric layer 3 and a composite mesh layer 4 which are arranged in sequence and fixedly connected. The composite mesh layer includes two layers of plastic mesh and a fertilizer bag 5 inserted into the two layers of plastic mesh. The paper layer 1, the plant seed and fertilizer mixed layer 2, the non-woven fabric layer 3 and the composite mesh layer 4 are fixedly connected to form an integral structural layer by pressing. Hot pressing is preferred, and no other fixing components and adhesives are required. A plurality of fertilizer bags 5 are provided, and are arranged in parallel with equal spacing between the two layers of plastic mesh. The size of the long-lasting green vegetation net in this embodiment is 1020mm*365mm*220mm

[0026] The plastic mesh layer can be made of PP950D flat wire and PE380D round wire. It is used to fix seeds and fertilizers in the early stage. It does not need to be fixed in the later stage when the grass grows up. It will automatically degrade after 2 to 3 years. You can also choose to weave degradable plastic wire into mesh, such as polylactic acid (PLA), polyhydroxyalkanoate (PHA), polyhydroxyalkanoate (PHA), carbon dioxide copolymer (PPC) or copolymer of butylene adipate and butylene terephthalate (PBAT).

[0027] The plant seed and fertilizer mixed layer is obtained by stirring and mixing plant seeds (grass seeds or tree seeds) and fertilizers (such as long-acting slow-release fertilizers or soil conditioners).

[0028] Example 2

[0029] In this embodiment, only the net layer is a single-layer plastic net, and the rest is the same as in embodiment 1. Compared with embodiment 1, the structure is simpler, the production is easier, and the cost is lower. However, the effect of embodiment 1 is longer-lasting.

[0030] Example 3

[0031] A long-term greening vegetation net fixing structure includes a plurality of long-term greening vegetation nets spread on a slope and a fixing component for fixing the long-term greening vegetation nets; Figure 2 As shown, the paper layer 1 of the long-lasting greening vegetation net is attached to the slope surface, and the composite net layer 4 is located on the upper part; the fixing parts include anchor pins 6 and thumbtacks 7; the anchor pins 6 are fixed to one side of the fertilizer bag 5 with their heads facing upwards, and their tails are inserted into the slope surface; the thumbtacks 7 pass through the fertilizer bag 5 from the upper center position of the fertilizer bag 5 and are inserted into the slope surface.

[0032] The above-mentioned embodiments are only partial embodiments of the present invention and cannot cover all of the present invention. Based on the above-mentioned embodiments and drawings, technical personnel in this field can obtain more implementation methods without paying creative work. Therefore, these implementation methods obtained without paying creative work should be included in the protection scope of the present invention.
