Description

Technical Field

[0001] The invention belongs to the technical field of ecological restoration, and specifically relates to a water-retaining vegetation ecological restoration material and a use method thereof. Background Art

[0002] Gansu has a long and narrow terrain with a wide latitude range. The regional climate types are complex and diverse, including mountains, plateaus, river valleys, deserts, plains and other terrains. The climate is dry and the annual rainfall is small. Natural factors have a great impact, the drought range is wide, the water and soil resources are not matched, and the area is large, but the vegetation coverage rate is low and unevenly distributed. Therefore, artificial ecological restoration is needed to increase the vegetation coverage rate. In addition to the required nutritional resources, the supply of water is the key to the growth of vegetation, especially for areas with less water resources and drought. Therefore, how to improve the water supply for vegetation is the key.

[0003] In response to the above problems, some solutions in the prior art include improving the overall soil structure in the original area by digging ditches or setting up special structures to store water, and then planting vegetation on the structure. This method can improve the water shortage problem to a certain extent, but in the specific implementation, the construction volume is large and the construction technology requirements are high. For areas with a large area, the construction efficiency is low. Another method is to add water-retaining components to the soil when planting vegetation. Although it has a certain degree of water-retaining effect, these components are relatively dispersed, the water storage effect is poor, and water is easily lost. Therefore, how to improve the water supply of vegetation in a simple way is a problem that needs to be solved. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a water-retaining vegetation ecological restoration material and a method for using the same.

[0012] Preferably, a plurality of water inlet pipes are distributed on the outer wall of the implant, and a cover body is provided on the water inlet pipes; a plurality of water level pipes are connected to the surface of the implant, and the tops of the water level pipes pass through the grid body, and the water inlet pipes and the water level pipes are both transparent.

[0013] Preferably, the implant is a square cavity structure made of a third textile.

[0014] Preferably, the water absorbent body is a water absorbent gel.

[0015] Preferably, the matrix is ​​made of the following raw materials in parts by weight: 50-70 parts of planting soil, 8-15 parts of cotton wool yarn, and 10-15 parts of wheat straw.

[0016] Preferably, the cotton wool thread body refers to cotton wool twisted into a rope with a length of 3-5 cm.

[0017] Preferably, the wheat straw refers to wheat straw cut into straw segments with a length of 2-4 cm.

[0018] Preferably, the preparation method of the matrix is:

[0019] Weigh the following raw materials in parts by weight respectively: 50-70 parts of planting soil, 8-15 parts of cotton wool threads, and 10-15 parts of wheat straw; take a portion of the planting soil and mix it evenly with the weighed cotton wool threads and wheat straw, and then cover the remaining planting soil to the surface of the mixed substrate; the mass of the portion of planting soil is 60%-80% of the mass of the weighed planting soil.

[0020] The second object of the present invention is to provide a method for using the above-mentioned water-retaining vegetation ecological restoration material, comprising the following steps:

[0021] S1. Using the third textile and the first textile to prepare an implant having an implant cavity, and filling the dry water-absorbing body into the implant to obtain a semi-finished product; folding the semi-finished product and carrying it to the area to be repaired; first covering the surface of the area to be repaired with the second textile, then laying the semi-finished product on the second textile, and fixing the second textile and the semi-finished product to the ground; filling the implant cavity with a matrix, then covering the mesh body, and fixing the mesh body to the surface of the implant;

[0022] S2. When using for the first time, first inject water into the implant through the water inlet pipe and observe the water level in the water level pipe.

When the water level drops or no water is observed, inject water into the implant through the water inlet pipe.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In order to solve the problem of inconvenient water supply in arid areas during ecological restoration, the present application provides a vegetation ecological restoration material with a water-retaining function, which has a simple implementation process and a good water-retaining effect, and can reduce the number of irrigation times. The traditional method of improving the water-retaining function of soil is to add a water-retaining agent to the soil. The present invention proposes a new water-retaining strategy, which arranges water-absorbing materials into cavities, fills the cavities with planting soil and seeds, divides large areas of planting areas into blocks, refines the planting areas, and wraps a water-absorbing body around each small planting area. When the moisture in the soil decreases, the moisture in the water-absorbing body will be absorbed. The above-mentioned setting increases the water storage capacity of the soil, and can replenish moisture to the soil in time according to the moisture content of the soil, thereby avoiding the occurrence of drought problems; and because the water-absorbing body is arranged around each planting cavity, it can ensure that the vegetation fully obtains moisture, that is, it can ensure the uniformity of moisture. When there is natural precipitation, the water-absorbing body can store rainwater in time to reduce the number of irrigation times;

[0025] In order to further improve the water retention effect and reduce the number of irrigation times, cotton wool and wheat straw are added to the planting soil. Wheat straw has a cavity structure, which can increase the porosity of the soil and provide a channel for water. Cotton wool is made into a rope of a certain length and placed in the soil. On the one hand, it has a certain degree of water retention function, and on the other hand, it has a water-conducting function, which guides the water in the water-absorbing body to various areas in the soil, thereby improving the uniformity of water distribution.

[0026] The implant of the present invention is made of textile and can therefore be folded. In specific implementation, the dry water-absorbing body can be first filled into the implant to make a semi-finished product. This process can be uniformly processed in a factory, and then the semi-finished product is transported to the area where it is needed, spread on the ground, and directly filled with matrix materials such as planting soil, sow or transplant vegetation, and inject water to allow the water-absorbing body to absorb water. Daily, it is only necessary to observe the water level in the implant and inject water as needed. Compared with traditional renovation methods such as digging ditches, the operation process of the present invention is simple, the renovation efficiency is greatly improved, and it is very suitable for large-scale renovation. In addition, the present invention improves the moisture content in the vegetation system through the improvement of the above-mentioned structure and matrix, has the function of storing water and long-term water supply, reduces the degree of dependence on external moisture, and reduces the number of manual irrigation times, and is particularly suitable for ecological restoration in arid areas.

[0031] In order to enable those skilled in the art to better understand and implement the technical solution of the present invention, the present invention is further described below in conjunction with specific embodiments and drawings, but the embodiments are not intended to limit the present invention.

[0032] Gansu is arid and water resources are scarce, resulting in low vegetation coverage. Traditional water-retention methods have complicated construction processes or insufficient water-retention performance, and the two cannot be combined. For this reason, the present application provides a vegetation ecological restoration material with water-retention function and proposes a new water-retention strategy. Generally speaking, a large area of ​​planting area is divided into blocks, the planting area is refined, and a water-absorbing body is wrapped around each small planting area, and the water-absorbing materials are arranged into cavities, and the cavities are filled with planting soil and seeds. When the moisture in the soil decreases, the moisture in the water-absorbing body will be absorbed. The above-mentioned setting increases the water storage capacity of the soil and can replenish moisture to the soil in time according to the moisture content of the soil, thereby avoiding the occurrence of drought problems; and because the water-absorbing body is arranged around each planting cavity, it can ensure that the vegetation obtains sufficient moisture, that is, the uniformity of moisture can be guaranteed. When there is natural precipitation, the water-absorbing body can store rainwater in time to reduce the number of watering.

[0033] Specifically, Figure 1 and Figure 2 As shown, including:

[0034] The implant 1 is made of a flexible material and can be folded or rolled into a cylinder for easy transportation. For example, the implant 1 of the present invention is a square cavity structure made of a third textile. The preparation process can be completed in a processing plant and does not require operation at a specific implementation site. It is suitable for large-scale integrated processing; a plurality of implant cavities 2 are evenly distributed in the implant 1, and the top and bottom of the implant cavity 2 extend to the surface and bottom of the implant 1 respectively, and the side walls of the implant cavity 2 are composed of a first textile 21; the implant cavity 2 is filled with a matrix 6; the interior of the implant 1 outside the implant cavity 2 is a hollow structure, and the hollow structure is filled with a water absorbent body 3, and the side walls of the implant cavity 2 are covered by the water absorbent body 3, and the water in the water absorbent body 3 enters the matrix 6 through the first textile 21.

[0035] The water-absorbing body 3 can be used to absorb water and store it. The water-absorbing body 3 is a water-absorbing gel. The reason is that the water-absorbing gel has a small volume when dry, but a large water absorption capacity and is easy to use. When the matrix 6 located in the planting cavity 2 lacks water, the water in the water-absorbing body 3 can enter the matrix 6 to always keep the matrix in a hydrated state. It can be seen from the above structure that the present invention divides a large area of ​​land into fine parts, and the water-absorbing body 3 is wrapped around the small areas divided. This can not only ensure the uniformity of water distribution in the entire land, but also increase the overall water storage capacity. Compared with the traditional method of mixing the water-absorbing body with the matrix, the water absorption capacity is increased. This is because, in the traditional method, the water-absorbing body is mixed with the matrix, and its particle size is small, the water storage capacity of a single water-absorbing body is small, and it is easy to lose water. The water storage capacity can be increased by increasing the content of the water-absorbing body, but because it is mixed with the matrix, the increase in the content of the water-absorbing body will affect the absorption of nutrients in the matrix by the prepared root system; therefore, the above-mentioned setting of the present invention can not only increase the water storage capacity, but also ensure the uniformity of water distribution.

[0036] On the basis of the above structure, the present invention also includes a grid body 5, which is arranged above the implant 1 and is fixedly connected to the implant 1 on all sides; the grid body 5 is used to fix the matrix and the entire structure to prevent the matrix from being lost due to natural conditions in the early stage of vegetation growth; and also includes a second textile 4, which is arranged below the implant and is fixedly connected to the implant on all sides. The second textile 4 can fix the bottom of the matrix layer to prevent loss.

[0037] In order to facilitate water injection into the implant 1, a plurality of water inlet pipes 11 are distributed on the outer wall of the implant 1, and a cover body is provided on the water inlet pipe 11; a plurality of water level pipes 12 are connected to the surface of the implant 1, and the top of the water level pipe 12 passes through the grid body 5. The water inlet pipe 11 and the water level pipe 12 are transparent bodies. The reason for setting them as transparent bodies is to facilitate observation of the water level so as to replenish water to the implant in time. When using it for the first time, first inject water into the implant 1 through the water inlet pipe 11, and observe the water level in the water level pipe 12. When the water level reaches the set position, stop injecting water, and cover the entrance of the water inlet pipe 11 with the cover body; observe the water level in the water inlet pipe 11 and the water level pipe 12 daily. When the water level drops or no water is observed, inject water into the implant 1 through the water inlet pipe 11.

[0038] like Figure 2 As shown, in order to further improve the water retention effect and reduce the number of irrigation times, cotton wool threads 62 and wheat straw 61 are added to the planting soil. The wheat straw has a cavity structure, which can increase the porosity of the soil and provide a channel for water. The cotton wool is made into a rope with a certain length and placed in the soil. On the one hand, it has a certain degree of water retention function, and on the other hand, it has a water-conducting function, which guides the water in the water-absorbing body to various areas in the soil, thereby improving the uniformity of water distribution. Specifically, the matrix 6 is made of the following raw materials in parts by weight: 50-70 parts of planting soil, 8-15 parts of cotton wool threads, and 10-15 parts of wheat straw. The cotton wool threads refer to cotton wool twisted into ropes with a length of 3-5 cm; the wheat straw refers to wheat straw cut into straw segments with a length of 2-4 cm.

[0039] In addition, the method for using the water-retaining vegetation ecological restoration material of the present invention comprises the following steps:

[0040] Before the specific implementation, the semi-finished product is first processed in the processing plant, and then the semi-finished product is transported to the site where it needs to be implemented. Specifically, the third textile and the first textile 21 are used to prepare the implant 1, and the dry water-absorbing body 3 is filled into the implant 1 to obtain the semi-finished product; the semi-finished product is folded and transported to the area to be repaired; the surface of the area to be repaired is first covered with the second textile 4, and then the semi-finished product is laid on the second textile 4, and the second textile 4 and the semi-finished product are fixed to the ground; the matrix 6 is filled into the implant cavity 2, and then the grid body 5 is covered, and the grid body 5 is fixed to the surface of the implant 1; it needs to be strongly It is noted that in terms of matrix preparation, there are also the following steps: weigh the following raw materials in parts by weight respectively: 50-70 parts of planting soil, 8-15 parts of cotton wool thread, and 10-15 parts of wheat straw; take a part of the planting soil and mix it evenly with the weighed cotton wool thread and wheat straw, and then cover the remaining planting soil to the surface of the mixed matrix (surface planting soil 63); the mass of the part of planting soil is 60%-80% of the mass of the weighed planting soil. The purpose of this setting is to prevent water from being lost through the surface of the matrix, so the cotton wool thread and wheat straw are placed inside the matrix without being exposed to the surface. When used for the first time, first inject water into the implant 1 through the water inlet pipe 11, and observe the water level in the water level pipe 12. When the water level reaches the set position, stop injecting water, and cover the entrance of the water inlet pipe 11 with the cover body; observe the water levels in the water inlet pipe 11 and the water level pipe 12 on a daily basis. When the water level drops or no water is observed, inject water into the implant 1 through the water inlet pipe 11. Through the above structure and method, the moisture content in the vegetation system is increased, and the system has the function of storing water and supplying water for a long time, which reduces the dependence on external moisture and the number of artificial irrigation. It is particularly suitable for ecological restoration in arid areas. In addition, it can be seen from the above that the implant of the present invention is made of textiles, so it can be folded. In the specific implementation, the dry water-absorbing body can be filled in the implant first to make a semi-finished product. This process can be processed uniformly in the factory, and then the semi-finished product is transported to the area where it is needed. The semi-finished product is spread on the ground and directly filled with planting soil and other matrix materials, sowing or transplanting vegetation, and injecting water to allow the water-absorbing body to absorb water. Daily, it is only necessary to observe the water level in the implant and inject water as needed. Compared with traditional transformation methods such as digging ditches, the operation process of the present invention is simple, which greatly improves the transformation efficiency and is very suitable for large-scale transformation.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, they are also intended to be included.
