Description

Technical Field

[0001] The present application relates to the field of greening technology, and in particular to a vegetation blanket. Background Art

[0002] Vegetation blanket technology is a new technology that is effectively used in slope protection, abandoned mine protection and other areas. Ecological slope protection is a slope protection method that uses the mechanical and hydrological effects of plants, mainly by promoting seed germination, accelerating growth, and preventing soil erosion. There are many ways to assist seed growth and development, but at the same time, it is necessary to strengthen soil and water conservation during seed germination to prevent the reduction of seed germination rate. Vegetation blankets are used to cover bare soil to reduce the erosion of the slope by surface runoff, and the vegetation blanket also provides good conditions for seed germination. However, the existing vegetation blankets are not stable when hung on the slope, and the vegetation blankets cannot play a good role in preventing topsoil erosion. Utility Model Content

[0003] The embodiment of the present application provides a vegetation blanket, which can improve the fixing effect of the vegetation blanket and play a better role in preventing surface soil erosion.

[0004] The embodiment of the present application provides a vegetation blanket, which includes a vegetation blanket body, which includes a first plant fiber layer, a nutrient layer, a seed layer, and a second plant fiber layer, which are sequentially distributed from bottom to top. The nutrient layer is arranged on the upper side of the first plant fiber layer, and the nutrient layer contains nutrients. The seed layer and the second plant fiber layer are sequentially located on the upper side of the nutrient layer. The vegetation blanket also includes a first reinforcement layer and a second reinforcement layer, which are respectively arranged on the upper and lower sides of the vegetation blanket body, and the first reinforcement layer and the second reinforcement layer are both coconut fiber meshes. The first reinforcement layer and the second reinforcement layer are mutually bound and connected, and are used to cover and reinforce the vegetation blanket body.

[0005] In this solution, the nutrient layer is arranged above the first plant fiber layer. The nutrient layer contains nutrients. The nutrient layer provides sufficient nutrients to the seeds in the seed layer during the growth stage, which is beneficial to the supply of nutrients required by the plants after the seeds in the vegetation blanket germinate. The first plant fiber layer and the second plant fiber layer provide a base layer for the vegetation blanket, which has a breathable function and is beneficial to the germination of seeds in the seed layer. By respectively arranging the first reinforcement layer and the second reinforcement layer on the upper and lower sides of the vegetation blanket body, the first reinforcement layer and the second reinforcement layer are both coconut fiber mesh, and the first reinforcement layer and the second reinforcement layer are mutually bound and connected to cover and reinforce the vegetation blanket body, the vegetation blanket body and the two reinforcement layers can be made into a whole, thereby improving the integrity of the vegetation blanket. Moreover, after the vegetation blanket is laid on the slope, since the first reinforcement layer and the second reinforcement layer are mesh structures, the hanging ability of the vegetation blanket and the slope can be increased, so that the vegetation blanket has a strong ability to resist water erosion. At the same time, after the vegetation blanket is laid, it has a strong anti-slip ability, so that the vegetation blanket can play a better role in preventing topsoil erosion.

[0006] In some embodiments, the coconut mesh is a grid-like structure having a plurality of mesh holes, and the shape of the mesh holes is square or diamond.

[0007] In the above technical solution, the coconut silk net has a plurality of mesh holes, and the plurality of mesh holes form a mesh structure, and the mesh holes can better contact and hang with the uneven soil on the surface of the slope, so that the vegetation blanket can be better hung on the slope. The shape of the mesh holes can be square or diamond, which is more flexible, and the vegetation blanket can be laid more firmly on the slope, ensuring that the vegetation blanket has a strong ability to resist water erosion.

[0008] In some embodiments, a polylactic acid film layer is further disposed between the seed layer and the nutrient layer.

[0009] In the above technical scheme, a polylactic acid film layer is provided between the seed layer and the nutrient layer, and the polylactic acid film layer is located below the seed layer, providing a preliminary fixing effect to the seeds in the seed layer, which is convenient for the germination of the seeds. Compared with the case where the polylactic acid film layer is not provided, the seeds are not easy to fall after passing through the pores of the first plant fiber layer. In addition, the polylactic acid film layer has the functions of water retention, heat preservation, and improvement of the soil ecological environment, and can also improve the early growth environment of the grass seeds in the humus layer. In the early germination of the seeds in the seed layer, the polylactic acid film layer cooperates with the second plant fiber layer and is respectively located on the upper and lower sides of the seeds. The polylactic acid film layer reduces the probability of water loss, can provide a certain water retention function for the seeds, and is conducive to better germination of the seeds. After the seeds germinate, the roots of the seeds extend into the soil through the polylactic acid film layer, which can absorb nutrients in the nutrient layer, which is conducive to the growth of vegetation.

[0010] In some embodiments, the thickness of the polylactic acid film layer is 0.01 mm-0.02 mm.

[0011] In the above technical solution, the thickness of the polylactic acid film layer is controlled within the range of 0.01mm-0.02mm, which can not only ensure the moisture demand of the seed layer during the germination stage of the seeds, but also make it easy for the roots of the seeds to penetrate the polylactic acid film layer and extend into the soil after germination.

[0012] In some embodiments, the first plant fiber layer and the second plant fiber layer are plant fiber layers both containing flax fibers and / or jute fibers.

[0013] In the above technical solution, the first plant fiber layer and the second plant fiber layer are plant fiber layers both containing flax fiber and / or jute fiber. The material of the plant fiber layer can be selected according to actual conditions to achieve a breathable function.

[0014] In some embodiments, the first plant fiber layer is a composite layer including flax fibers and jute fibers.

[0015] In the above technical scheme, the first plant fiber layer is a composite layer of flax fiber and jute fiber. Relatively loose pores are left in the first plant fiber layer to facilitate the roots of seeds after germination to pass through the first plant fiber layer. The first plant fiber layer can effectively inhibit the production of pests in the vegetation blanket, protect the seedlings and the vegetation blanket, and is conducive to the germination of seeds and the growth and development of plants.

[0016] In some embodiments, the second plant fiber layer is a composite layer containing flax fiber and jute fiber; wherein, in the second plant fiber layer, the content ratio of flax fiber to jute fiber is 3:7.

[0017] In the above technical solution, the second plant fiber layer is a composite layer of flax fiber and jute fiber. Relatively loose pores are also left in the second plant fiber layer. While facilitating plant germination, the second plant fiber layer and the first plant fiber layer cooperate and are respectively located on the upper and lower sides of the seed layer, which can effectively inhibit the production of pests in the vegetation blanket, protect the seedlings and the vegetation blanket, and is conducive to seed germination and plant growth and development.

[0018] In some embodiments, the first plant fiber layer and the second plant fiber layer have equal thickness.

[0019] In some embodiments, the nutrient layer includes water-soluble fertilizer particles, and at least some of the water-soluble fertilizer particles in the nutrient layer are embedded in the first plant fiber layer.

[0020] In the above technical solution, part of the water-soluble fertilizer particles in the nutrient layer are embedded in the first plant fiber layer, so that after the vegetation blanket is laid, the plants have better nutrient supply.

[0021] In some embodiments, connecting belts and connecting buckles are respectively provided on opposite sides of the vegetation blanket, and the connecting buckles are used to connect with the connecting belts of adjacent vegetation blankets.

[0022] In the above technical solution, connecting belts and connecting buckles are respectively provided on opposite sides of the vegetation blanket. When multiple vegetation blankets are spliced ​​together, the connecting buckles on the vegetation blanket can be connected to the connecting belts of adjacent vegetation blankets, thereby connecting multiple vegetation blankets into a whole, thereby improving the integrity of the vegetation blanket and achieving a better fixing effect on the slope.

[0033] Example

[0034] The present application embodiment provides a vegetation blanket, see Figure 1 and Figure 2 The vegetation blanket 100 includes a vegetation blanket body, which includes a first plant fiber layer 20, a nutrient layer 30, a seed layer 50, and a second plant fiber layer 60, which are sequentially distributed from bottom to top. The nutrient layer 30 is arranged on the upper side of the first plant fiber layer 20, and the nutrient layer 30 contains nutrients. The seed layer 50 and the second plant fiber layer 60 are sequentially located on the upper side of the nutrient layer 30. The vegetation blanket 100 also includes a first reinforcement layer 10 and a second reinforcement layer 70, which are respectively arranged on the upper and lower sides of the vegetation blanket body, and the first reinforcement layer 10 and the second reinforcement layer 70 are both coconut fiber mesh. The first reinforcement layer 10 and the second reinforcement layer 70 are mutually bound and connected, and are used to cover and reinforce the vegetation blanket body.

[0035] In this solution, the nutrient layer 30 is arranged above the first plant fiber layer 20. The nutrient layer 30 contains nutrients. The nutrient layer 30 provides sufficient nutrients to the seeds in the seed layer 50 during the growth stage, which is beneficial to the supply of nutrients required by the plants after the seeds in the vegetation blanket germinate. The first plant fiber layer 20 and the second plant fiber layer 60 provide the vegetation blanket with a base layer, which has a breathable function and is beneficial to the germination of the seeds in the seed layer 50. The first reinforcement layer 10 and the second reinforcement layer 70 are respectively arranged on the upper and lower sides of the vegetation blanket body. Both the first reinforcement layer 10 and the second reinforcement layer 70 are coconut silk mesh. The first reinforcement layer 10 and the second reinforcement layer 70 are mutually bound and connected, and the vegetation blanket body is covered and reinforced, so that the vegetation blanket body and the two reinforcement layers can become a whole, thereby improving the integrity of the vegetation blanket. Moreover, after the vegetation blanket is laid on the slope, since the first reinforcement layer 10 and the second reinforcement layer 70 are mesh structures, the hanging ability of the vegetation blanket and the slope can be increased, so that the vegetation blanket has a strong ability to resist water erosion. At the same time, after the vegetation blanket 100 is laid, it has a strong anti-slip ability, thereby allowing the vegetation blanket to play a better role in preventing topsoil erosion.

[0036] Among them, the coconut silk net is a coconut fiber net. The first reinforcement layer 10 and the second reinforcement layer 70 are made of coconut silk net, which has the following advantages: 1. Flexibility: The coconut silk net has high tensile strength and is suitable for laying on irregular slopes, which can reduce the workload of slope repair. 2. Environmental protection: The coconut silk net naturally degrades into organic soil, which is very environmentally friendly. 3. Anti-scouring: When the slope is not covered with vegetation, the coconut silk net can resist rainwater erosion and runoff velocity up to 3m / s, which can resist heavy rain erosion. When the plants grow lushly, the runoff velocity that can resist erosion reaches 6m / s, which is more than twice that of ordinary turf, protecting the soil and reducing soil erosion. 4. Corrosion resistance: The coconut silk net is a natural plant fiber, containing higher lignin than ordinary plant fibers, and has a longer life than plant fibers such as jute, so it is more resistant to corrosion. 5. Moisture retention: The presence of coconut silk net has a significant effect on reducing the evaporation of water in the slope soil and increasing the infiltration volume. 6. Industrialization: Coconut fiber net is an industrialized product. When the construction is very tight, it can greatly reduce the working time of the slope, so that the formed coconut fiber net can be covered in a very short time to resist the erosion of rainwater. 7. Marketization: Replace the plastic three-dimensional net and the skeleton slope protection, and can make vegetation grow on the rock. Low price, low maintenance cost and good treatment effect.

[0037] In some embodiments, the coconut silk net is a grid structure, and the coconut silk net has a plurality of meshes, and the shape of the meshes is square or rhombus. The coconut silk net has a plurality of meshes, and the plurality of meshes constitute a mesh structure, and the meshes can better contact and hang with the uneven soil on the surface of the slope, so that the vegetation blanket can be better hung on the slope. The shape of the mesh can be square or rhombus, which is more flexible, and the vegetation blanket can be laid more stably on the slope, ensuring that the vegetation blanket has a strong ability to resist water erosion.

[0038] In some embodiments, a polylactic acid film layer 40 is further provided between the seed layer 50 and the nutrient layer 30. By providing the polylactic acid film layer 40 between the seed layer 50 and the nutrient layer 30, the polylactic acid film layer 40 is located below the seed layer 50, providing a preliminary fixation effect for the seeds in the seed layer 50, facilitating the germination of the seeds, and compared with not providing the polylactic acid film layer 40, the seeds are not easy to fall through the pores of the first plant fiber layer 20. In addition, the polylactic acid film layer 40 has the functions of water retention, heat preservation, and improvement of soil ecological environment, and can also improve the early growth environment of grass seeds in the humus layer. In the early stage of germination of seeds in the seed layer 50, the polylactic acid film layer 40 and the second plant fiber layer 60 cooperate and are respectively located on the upper and lower sides of the seeds. The polylactic acid film layer 40 reduces the probability of water loss and can provide a certain water retention function for the seeds, which is conducive to better germination of the seeds. After the seeds germinate, the roots of the seeds extend into the soil through the polylactic acid film layer 40, and can absorb nutrients in the nutrient layer 30, which is conducive to the growth of vegetation.

[0039] The polylactic acid (PLA) film layer is a degradable material, and its raw material is starch fermentation, that is, polylactic acid film. The polylactic acid film layer 40 is similar to a ground film, and has air permeability, oxygen permeability and carbon dioxide permeability functions, and is a biodegradable plastic with excellent antibacterial and anti-mildew properties.

[0040] In this embodiment, the seeds in the seed layer 50 may be alfalfa, and the seed content is 5-7 g / m2.

[0041] In some embodiments, the thickness of the polylactic acid film layer 40 is 0.01 mm-0.02 mm. Controlling the thickness of the polylactic acid film layer 40 within the range of 0.01 mm-0.02 mm can not only ensure the moisture demand of the seed layer 50 during the germination stage of the seeds, but also make it easier for the roots of the seeds to penetrate the polylactic acid film layer 40 and extend into the soil after germination.

[0042] In some embodiments, the first plant fiber layer 20 and the second plant fiber layer 60 are plant fiber layers both containing flax fiber and / or jute fiber. The first plant fiber layer 20 and the second plant fiber layer 60 are plant fiber layers both containing flax fiber and / or jute fiber. The material of the plant fiber layer can be selected according to actual conditions to achieve a breathable function.

[0043] In some embodiments, the first plant fiber layer 20 is a composite layer including flax fiber and jute fiber. The first plant fiber layer 20 is a composite layer of flax fiber and jute fiber, and relatively loose pores are left in the first plant fiber layer 20, which facilitates the root system of the seed after germination to pass through the first plant fiber layer 20, and the first plant fiber layer 20 can effectively inhibit the generation of pests in the vegetation blanket, protect the seedlings and the vegetation blanket, and facilitate the germination of seeds and the growth and development of plants.

[0044] Among them, in the first plant fiber layer 20, the content ratio of flax fiber and jute fiber is 3:7. Of course, the content ratio of flax fiber and jute fiber can be adjusted according to actual conditions.

[0045] In some embodiments, the second plant fiber layer 60 is a composite layer containing flax fiber and jute fiber; wherein, in the second plant fiber layer 60, the content of flax fiber and jute fiber accounts for 3:7. The second plant fiber layer 60 is a composite layer of flax fiber and jute fiber, and relatively loose pores are also left in the second plant fiber layer 60. While facilitating plant germination, the second plant fiber layer 60 cooperates with the first plant fiber layer 20, and is respectively located on the upper and lower sides of the seed layer 50, which can effectively inhibit the production of pests in the vegetation blanket, protect the seedlings and the vegetation blanket, and facilitate the germination of seeds and the growth and development of plants.

[0046] In some embodiments, the first plant fiber layer 20 and the second plant fiber layer 60 have the same thickness.

[0047] In some embodiments, the nutrient layer 30 includes water-soluble fertilizer particles, and at least some of the water-soluble fertilizer particles in the nutrient layer 30 are embedded in the first plant fiber layer 20. By embedding some of the water-soluble fertilizer particles in the nutrient layer 30 in the first plant fiber layer 20, the vegetation blanket has better nutrient supply for plant growth after laying.

[0048] Among them, the fertilizer in the nutrient layer 30 is an inorganic salt-soluble fertilizer. During the production process of the vegetation blanket, the nutrient layer 30 is sprayed on the first plant fiber layer 20 with an inorganic salt-soluble fertilizer and dried. That is, part of the nutrient layer 30 is located in the first plant fiber layer 20, so that the nutrient layer 30 is not easily lost.

[0049] In some embodiments, a connecting belt 81 and a connecting buckle 80 are respectively provided on opposite sides of the vegetation blanket 100, and the connecting buckle 80 is used to connect with the connecting belt 81 of an adjacent vegetation blanket. By providing the connecting belt 81 and the connecting buckle 80 on opposite sides of the vegetation blanket, when multiple vegetation blankets are spliced, the connecting buckle 80 on the vegetation blanket can be connected with the connecting belt 81 of the adjacent vegetation blanket, so that the multiple vegetation blankets are connected as a whole, thereby improving the integrity of the vegetation blanket, and the vegetation blanket 100 has a better fixing effect on the slope.
