[0020] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0021] The terms used in the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "the" and "the" used in the present invention and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0022] Although relative terms such as "upper" and "lower" are used in the present invention to describe the relative relationship of one component of the illustration to another component, these terms are used in the present invention only for convenience, such as the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned over and turned upside down, the component described as being "upper" will become the component "lower". Other relative terms such as "high", "low", "top", "bottom", "front", "back", "left", "right", etc. are also used to have similar meanings. When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0023] According to a first aspect of an embodiment of the present invention, referring to Figure 1 As shown, a ground film structure for improving the utilization efficiency of water resources in arid areas is provided, and the ground film structure comprises: Several mulches set up in succession; Among them, the ground film includes an underground anti-seepage part 1 and an above-ground anti-evaporation part 2, the underground anti-seepage part 1 and the above-ground anti-evaporation part 2 are connected and the connection 3 is used for planting plants, the above-ground evaporation part of the previous ground film and the underground anti-seepage part 1 of the latter ground film are enclosed to form a water retention space 4, and the water in the water retention space 4 can penetrate into the roots of the plants through the connection 3 to provide moisture for the plants.

[0024] The underground anti-seepage part 1 can effectively prevent water from leaking into the deep underground layer, reducing the waste of water resources; the above-ground anti-evaporation part 2 can greatly reduce the amount of water lost due to evaporation. The combination of the two can significantly improve the utilization efficiency of limited water resources in arid areas, thereby creating a relatively moist local environment for plants and reducing the stress of drought on plants.

[0025] The existence of the water-retaining space 4 can store natural precipitation or artificial water, and the water in the water-retaining space 4 can penetrate into the roots of plants through the connection 3, continuously providing a source of water for plant growth, ensuring that plants can obtain sufficient water supply even in arid environments, thereby improving the survival rate and growth rate of plants in arid areas.

[0026] The mulch structure of the present invention combined with plant planting can also play a certain role in sand fixation, reduce the erosion of soil in arid areas by wind and sand, and help maintain the ecological balance in arid areas. Moreover, with the growth and reproduction of plants, it can help improve the ecological environment in arid areas, provide suitable living and growing conditions for other organisms in the current area, and promote the recovery and development of the ecosystem in arid areas.

[0027] In some embodiments, the underground anti-seepage part 1 and the above-ground anti-evaporation part 2 can be provided separately. In this way, when the underground soil conditions change or the anti-seepage part is damaged, the underground anti-seepage part 1 can be replaced alone without replacing the entire ground membrane structure. Similarly, if the above-ground anti-evaporation part 2 deteriorates in performance due to long-term exposure to wind and sun, it can also be replaced alone, thereby improving the flexibility and sustainable use of the ground membrane structure.

[0028] However, in arid areas, there may be severe natural conditions such as strong winds and dust. In order to enhance the anti-leakage and anti-evaporation effects while improving the stability of the ground membrane structure, in an embodiment of the present invention, the underground anti-seepage part 1 and the above-ground anti-evaporation part 2 are integrally formed.

[0029] In this way, the underground anti-seepage part 1 and the above-ground anti-evaporation part 2 are tightly connected and seamless. On the one hand, it can avoid the problem of water leakage or increased evaporation caused by the loose connection between the two parts, thereby enhancing its anti-leakage and anti-evaporation effects; on the other hand, this structure can better resist the impact of external forces, and is not prone to separation, breakage, etc., ensuring that the ground film structure can play a long-term and stable role and continuously provide a good moisture environment for plant growth. Moreover, the one-piece design can reduce the production process and complexity, improve production efficiency, and reduce production costs. During the laying process, it is also more convenient and quick, which can effectively reduce the construction difficulty and time cost, and is conducive to large-scale promotion and application in arid areas.

[0030] Taking into account the water collection effect, in some exemplary embodiments of the present invention, the above-ground evaporation prevention part 2 is in contact with the surface soil matrix and is arranged in a ridge-like structure with a central bulge.

[0031] This design allows rainwater or irrigation water to flow down the sides of the ridge structure and gather in the planting area, thereby increasing the residence time and collection volume of water on the surface, providing more available water resources for plants. The top of the ridge structure is relatively high, which can reduce the area of ​​direct sunlight on the soil surface, thereby reducing the evaporation rate of water. At the same time, because the two sides of the ridge structure are relatively low, a certain shade area can be formed, further reducing the evaporation loss of water and improving the utilization efficiency of water resources.

[0032] In addition, the ridge structure can make the planting area more regular, facilitate field management operations such as weeding, fertilization, pest and disease control, etc., and facilitate the layout of irrigation and drainage systems, thereby improving the efficiency and management level of agricultural production.

[0033] In order to make full use of the collected water resources, in some exemplary embodiments of the present invention, the above-ground anti-evaporation portion 2 of the previous ground film is away from one side of its underground anti-permeability portion 1 and is bent at the connection 3 of the subsequent ground film to fit together with the underground anti-permeability portion 1 of the subsequent ground film, and the bending direction is the same as the extension direction of the underground anti-permeability portion 1 of the subsequent ground film.

[0034] In this way, since the bending direction is the same as the extension direction of the underground anti-permeability part 1 of the subsequent ground film, the water flow can be guided to flow more smoothly into the water retention space 4, which can not only provide a continuous water supply for the roots of plants, but also help avoid the disorderly flow of water on the surface and reduce water waste and loss.

[0035] The above-ground anti-evaporation part 2 of the previous ground film is bent at the connection 3 of the subsequent ground film and fits with the underground anti-permeability part 1 of the subsequent ground film, which can make the connection between adjacent ground films tighter. On the one hand, this close fit can effectively reduce the possibility of water leakage from the connection 3, enhance the sealing of the entire ground film structure, ensure that the water retention space 4 can better store water, and improve the utilization efficiency of water resources; on the other hand, it can improve the overall stability of the ground film structure, so that the entire ground film structure can better withstand the impact of severe weather in arid areas, prevent the ground film from being lifted or damaged, and thus increase the service life of the ground film structure.

[0036] In arid areas, land resources are often limited. In order to maximize the planting area on limited land and facilitate maintenance and management, in some implementations, reference Figure 1 As shown, the ground membranes can be designed to be arranged in an array.

[0037] Setting up the ground film in an array can not only plan the land space more reasonably and make full use of each piece of land resources, but also facilitate the management and maintenance of the ground film. For example, irrigation, fertilization, pest and disease control and other operations can be carried out in an orderly manner. Once a problem occurs in a certain area, it can be quickly located and resolved, reducing the impact on the entire planting area.

[0038] The water-retaining spaces 4 are more regularly and evenly distributed on the land, which can help to evenly store and supply water in the entire planting area, avoid excessive or insufficient water in some areas, improve the utilization efficiency of water resources, and create a more stable water environment for plant growth. And the neat array setting can make the planting area look more beautiful and standardized, and enhance the overall image of agricultural production. In arid areas, land resources are precious, in order to improve land utilization. In some embodiments, reference Figure 2 As shown, both the rows and columns of the array are used to grow plants.

[0039] In this way, every inch of land can be fully utilized and more plants can be planted. This means that the soil can be better fixed and soil erosion can be prevented. At the same time, the release of oxygen and the absorption of carbon dioxide can be increased, and the microclimate and ecological environment in arid areas can be improved. In addition, the root system of plants can also improve the soil structure and increase the soil's ability to retain water and fertilizer.

[0040] In addition, reasonable plant spacing and layout can form a good microecological environment between plants. For example, taller plants can provide some shade for lower plants and reduce water evaporation; planting different types of plants together can attract more beneficial insects and microorganisms, promote ecological balance, and thus be beneficial to plant growth and development.

[0041] According to a second aspect of the embodiment of the present invention, referring to Figure 3 As shown, a plant planting method is provided, comprising: S310: Divide the land into arrays; S320: Laying the above-mentioned ground membrane structure for improving the efficiency of water resource utilization in arid areas.

[0042] The present invention divides the land into arrays to make land planning more regular, fully utilize each piece of land, and avoid land waste. By laying the above-mentioned ground film structure in each area of ​​the array, planting can be achieved throughout the land, greatly increasing the planting area to improve the output potential of the land.

[0043] The ground membrane structure includes an underground anti-seepage part 1 and an above-ground anti-evaporation part 2, which can effectively prevent water leakage and evaporation loss. The water retention space 4 is designed to store natural precipitation or artificial water, and penetrate into the roots of plants through the connection 3 to provide a continuous water supply for the plants.

[0044] The protective effect of the mulch can reduce the adverse effects of external environmental factors on plants, such as strong winds, high temperatures and dryness. At the same time, a stable water supply helps the development and growth of plant roots and improves the survival rate and growth rate of plants.

[0045] In arid areas, this planting method can play a role in fixing sand and conserving soil through plant growth and mulch covering, thereby reducing soil erosion and wind and sand damage.

[0046] According to a third aspect of an embodiment of the present invention, there is provided a sand fixation barrier, comprising: According to the above-mentioned ground film structure for improving the efficiency of water resource utilization in arid areas; The water-retaining spaces 4 of each film in the ground film structure are used to wrap the sand, and the two ends of each film and the connection 3 are used to plant sand-fixing plants.

[0047] The water-retaining space 4 in the ground film structure is used to wrap the sand body, which can effectively fix the sand and prevent the sand from flowing. The existence of the water-retaining space 4 can reduce the evaporation of water on the surface of the sand body, maintain the humidity of the sand body, and thus increase the stability of the sand body.

[0048] Both ends of the film and the connection 3 are used to plant sand-fixing plants, and the roots of the plants can penetrate into the sand to further fix the sand. At the same time, the growth of plants can improve the soil structure, increase the fertility of the soil, provide a living environment for other organisms, and promote the recovery of the ecosystem.

[0049] The ground membrane structure can be made of low-cost materials, and the sand-fixing plants can be selected from local species that are suitable for local climate and soil conditions, reducing the planting cost. At the same time, the maintenance cost of the sand-fixing barrier is also low, requiring only regular watering and fertilization.

[0050] The growth of sand-fixing plants can improve soil structure, increase soil fertility, provide a living environment for other organisms, and promote the recovery of the ecosystem. At the same time, sand-fixing barriers can also provide ecological services to local residents, such as windbreak and sand fixation, water conservation, climate regulation, etc., and promote the sustainable development of the local economy.

[0051] The sand-fixing barrier also has the technical effect of the above-mentioned ground film structure for improving the efficiency of water resource utilization in arid areas, which will not be elaborated in the present invention.

[0052] According to a fourth aspect of an embodiment of the present invention, a ground film laying device is provided for laying a ground film structure as described above for improving the efficiency of water resource utilization in arid areas.

[0053] Compared with manual laying, ground film laying equipment can greatly improve laying speed and efficiency. Ground film laying equipment can accurately control the laying position and direction of the ground film, ensure that the joints 3 of the ground film are tightly fitted, and form an effective water retention space 4. At the same time, it can also ensure the fit between the ground film and the soil, improve the anti-leakage effect of the underground anti-seepage part 1 and the anti-evaporation effect of the above-ground anti-evaporation part 2. And the ground film laying equipment can apply uniform tension to the ground film during the laying process to avoid problems such as loosening and wrinkling of the ground film, so as to ensure the flatness and stability of the ground film and extend the service life of the ground film. It can also reduce the intensity of manual labor. The operator only needs to perform simple operations to complete the ground film laying work, which greatly reduces labor costs and labor intensity.

The invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
