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 sand fixation vegetation straw curtain net. Background Art

[0002] Artificial straw grid containment has high construction requirements for terrains 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 sand-fixing vegetation grass curtain net. The purpose of the utility model is achieved through the following technical solutions:

[0004] A sand-fixing vegetation straw curtain net is composed of an inner seed and fertilizer sandwich layer and an outer straw curtain pasted together, wherein the seed and fertilizer sandwich layer comprises paper layers on both sides and a plant seed and fertilizer mixed layer sandwiched in the middle.

[0005] For further optimization, the paper layers on both sides and the mixed layer of plant seeds and fertilizers sandwiched in the middle are fixedly connected by pressing.

[0006] For further optimization, the inner seed and fertilizer sandwich layer and the outer straw curtain are pressed or bonded together to form an integral structural layer.

[0007] The straw curtain is a net curtain woven from straw.

[0008] The paper layer is preferably virgin wood pulp paper.

[0009] 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.

[0010] The straw curtain is a single-layer curtain or a double-layer curtain.

[0011] According to a further optimization, the straw curtain is a double-layer curtain, and a fertilizer bag is arranged between the double-layer curtain.

[0012] Beneficial effects of the utility model:

[0013] The utility model curtain net is laid on exposed sand, sand dunes and hillsides, which can not only suppress the flying of sand, but also prevent soil erosion. After watering, plants can grow in the curtain net, and vegetation can be restored in a short time to achieve greening. It has the integrated functions of effectively fixing sand, preventing sand flow, and restoring vegetation; it can effectively solve the problems of wind and sand prevention and vegetation restoration in deserts, sand dunes and other areas.

[0014] The utility model product is suitable for different terrains, and the construction and laying only require simple fixing, and the construction is convenient and the adaptability is strong.

[0015] The straw curtain and the degradable paper in the curtain net of the utility model can be naturally degraded and are friendly to the environment; and no additional maintenance is required after the plants take root.

[0016] The straw curtain has the functions of heat insulation, cold protection, sun protection and moisturizing. The curtain net of the utility model can also effectively protect against sun and moisturize in areas with dry weather and little rain. The straw curtain can also be used as a fertilizer to promote plant growth after being decomposed in the later stage.

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example 1

[0024] like Figure 1 A sand-fixing vegetation straw curtain net is composed of an inner seed and fertilizer sandwich layer and an outer straw curtain 3 attached together, wherein the seed and fertilizer sandwich layer comprises paper layers 1 on both sides and a plant seed and fertilizer mixed layer 2 sandwiched in the middle.

[0025] In this embodiment, the paper layers 1 on both sides and the plant seed and fertilizer mixed layer 2 sandwiched in the middle are fixedly connected by pressing, and the seed and fertilizer sandwich layers on both sides and the outer straw curtain 3 are pressed to form an integral structural layer. Preferably, hot pressing is used, and no other fixing parts and adhesives are required, and the bonding can be completed after hot pressing.

[0026] The plant seed and fertilizer mixed layer is a mixture of plant seeds and fertilizers (such as long-acting slow-release fertilizers or soil conditioners), wherein the plant seeds include grass seeds and / or tree seeds. The straw curtain is a net curtain woven from straw. After watering, plants can grow in the gaps of the net. In this embodiment, the size of the sand-fixing vegetation straw curtain net is 1020mm*350mm*320mm. Figure 3As shown, multiple sand-fixing vegetation grass curtain nets are arranged and covered on the slope surface of the fill soil, and the surface is fixed with wooden nails, bamboo nails, iron nails or sandbags, and sprayed and irrigated after the construction is completed. The paper layer is original wood pulp paper.

[0027] Example 2

[0028] This embodiment is an optimization of embodiment 1. Figure 2 As shown, the straw curtain 3 is a double-layer curtain, and a fertilizer bag 4 is arranged between the double-layer curtains. The fertilizer attached to the straw curtain can further increase the fertility of the soil, so that some desert environments that are not suitable for plant growth can grow vegetation.

[0029] 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.
