The top covering layer is a hemp net coconut coir blanket, and the grass seed cloth is integrated, so the grass seeds are spread more evenly. On the one hand, the hemp net coconut coir blanket can be completely degraded and will not cause secondary pollution to the environment. On the other hand, it plays the role of covering the nutrient soil to prevent the nutrient soil from being scattered during transportation and construction. The product is generally The sutures are made of high-strength cotton thread, and the degradable bentonite blanket is a water-retaining layer. The degradable bentonite blanket is composed of a carrier cloth, bentonite and a cover cloth and is formed into a whole through a needle-punching process. The carrier cloth is made of one or more degradable materials such as cotton cloth, linen cloth, and viscose fiber cloth. The cover cloth is a degradable viscose fiber non-woven geotextile, linen fiber non-woven fabric, cotton and linen non-woven fabric or other degradable non-woven fabric.

The two layers are fixed, and the amount of bentonite paste applied in the middle is large. The mechanical properties of the product are better. The unit area mass of the nutrient layer is determined according to the pollution situation of the site. If the site is seriously polluted, the subsequent plant roots cannot penetrate and cannot absorb nutrients outside the nutrient layer. Therefore, the unit area mass of the nutrient layer needs to be increased. The nutrient layer should be greater than 4500g / m 2 If the site is less polluted and plants can grow on the site, the unit area weight of the nutrient layer does not need to be too heavy. The nutrient layer can be set to 3000g / m 2About, to provide the initial nutritional power for plant production, the covering layer is coconut palm blanket or linen mesh, cotton and linen blended fabric and other degradable materials, such as the cover cloth and carrier cloth used to produce degradable waterproof blanket can be used as the covering layer, which plays the role of binding the nutrient layer. When using linen mesh, cotton and linen blended fabric produced by weaving technology as the covering layer, the aperture between the yarns should not be too large to prevent the nutrient layer substances from spilling from the mesh. When using non-woven geotextiles, the material weight can be appropriately reduced to ensure that the grass is covered under the premise of ensuring that the covering effect is not affected. The seeds can grow smoothly. When using coconut palm blanket as the covering layer, it is preferred to use hemp net coconut palm blanket to ensure that all materials are degradable. Grass seed cloth is made of degradable materials. If grass seed cloth is used as the covering layer, the unit area weight of the grass seed cloth can be appropriately increased. If the grass seed cloth is integrated on hemp net cloth or coconut palm blanket, the unit area mass of the grass seed cloth can be appropriately reduced. The fully degradable ecological blanket has the functions of anti-seepage and water retention, which can provide initial nutrition for the growth of grass seeds, and the materials are all degradable and will not cause secondary pollution to the environment.

The bentonite is sodium-based bentonite, which has better anti-seepage and water retention effects. If the degradable bentonite blanket composed of carrier cloth, bentonite and cover cloth is mainly used for water retention, the unit area mass is generally less than 4000g / m 2 If there is a requirement for anti-seepage, the mass per unit area should be > 4000g / m 2 The grass seed layer 130 is laid on the upper, lower or middle position of the nutrient layer 120. The grass seed layer 130 is integrated into the product and can be a grass seed cloth, or grass seeds sown in the nutrient layer 120. If grass seeds are not integrated, grass seeds can also be sown after the fully degradable ecological blanket is laid and installed. The grass seeds are sown more evenly. The covering layer 140 is located on the top of the product. The degradable bentonite blanket 110, the nutrient layer 120, the grass seed layer 130 and the covering layer 140 are sewn into a whole. The suture line is a high-strength degradable yarn. The covering layer 140 is a linen net coconut coir blanket. The linen net coconut coir blanket is one or more degradable materials of coconut coir blanket, linen mesh or cotton and linen blended cloth. On the one hand, the linen net coconut coir blanket can be completely degraded and will not cause secondary pollution to the environment. On the other hand, it plays the role of covering the nutrient soil to prevent the nutrient soil from being scattered during transportation and construction.

[0019] Specifically, the working principle of the fully degradable ecological blanket is as follows: when in use, the bottom is a fully degradable bentonite blanket 110, which has the functions of anti-seepage and water retention. The middle is a graded plant nutrition layer 120, which provides initial nutrition for the growth of grass seeds. The top covering layer 140 is a hemp net coconut palm blanket, and the grass seed cloth is integrated to spread the grass seeds more evenly. On the one hand, the hemp net coconut palm blanket can be completely degraded and will not cause secondary pollution to the environment. On the other hand, it plays the role of covering the nutrient soil to prevent the nutrient soil from scattering during transportation and construction. The product is formed by stitching The suture line is a high-strength cotton thread, and the degradable bentonite blanket 110 is a water-retaining layer. The degradable bentonite blanket 110 is composed of a carrier cloth, bentonite and a cover cloth and is integrated into a whole through a needle-punching process. The carrier cloth material is one or more degradable materials such as cotton cloth, linen cloth, and viscose fiber cloth. The cover cloth is a degradable viscose fiber non-woven geotextile, linen fiber non-woven fabric, cotton and linen non-woven fabric or other degradable non-woven fabric. The bentonite adopts sodium-based bentonite, which has better anti-seepage and water-retaining effects. If the degradable bentonite blanket 110 is mainly used for water retention, the unit area mass is less than 4000g / m 2 If there is a requirement for anti-seepage, the mass per unit area should be > 4000g / m 2 The modified type of the degradable bentonite blanket 110 can be to apply bentonite paste on a rough degradable fabric such as linen mesh or cotton and linen blended fabric. The fabric surface is relatively rough, and a certain amount of bentonite paste can be adhered to the fabric. The thickness of the bentonite paste applied on a single layer of linen mesh is limited. The water retention layer can be a multi-layer linen mesh coated with bentonite paste stacked together as a common water retention layer. The mass of the single layer of bentonite paste is 1000g / m 2 The other method is to apply a layer of bentonite paste between two layers of linen or cotton and linen blended fabrics. The two layers are fixed, and the amount of bentonite paste applied in the middle is large. The mechanical properties of the product are better. The unit area mass of the nutrient layer is determined according to the pollution situation of the site. If the site is seriously polluted, the subsequent plant roots cannot penetrate and cannot absorb nutrients outside the nutrient layer. Therefore, the unit area mass of the nutrient layer needs to be increased. The nutrient layer should be greater than 4500g / m 2 If the site is less polluted and plants can grow on the site, the unit area weight of the nutrient layer does not need to be too heavy. The nutrient layer can be set to 3000g / m 2About 100g, which can provide the initial nutritional power for plant production. The covering layer is made of degradable materials such as coconut palm blanket, linen mesh, cotton and linen blended fabric, etc. For example, the cover cloth and carrier cloth used to produce degradable waterproof blanket can be used as the covering layer, which plays the role of binding the nutrient layer. When using linen mesh, cotton and linen blended fabric produced by weaving technology as the covering layer, the aperture between the yarns should not be too large to prevent the nutrient layer substances from spilling from the mesh. When using non-woven geotextiles, the material weight can be appropriately reduced while ensuring that the covering effect is not affected to ensure that the grass seeds can grow smoothly. When using coconut palm blanket as the covering layer, linen mesh and coconut palm blanket are preferred to ensure that all materials are degradable. The grass seed cloth is made of degradable materials. If grass seed cloth is used as the covering layer, the unit area weight of the grass seed cloth can be appropriately increased. If the grass seed cloth is integrated on the linen mesh or coconut palm blanket, the unit area mass of the grass seed cloth can be appropriately reduced. The fully degradable ecological blanket has the functions of anti-seepage and water retention, and can provide initial nutrition for the growth of grass seeds. The materials are all degradable and will not cause secondary pollution to the environment.
