Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, and in particular to mulch film structures for improving water resource utilization efficiency in arid regions. Background Technology

[0002] In arid regions, crops struggle to survive due to the dry topsoil, which is highly permeable and has low surface water retention capacity. As a result, large-scale cultivation is only possible in areas with guaranteed water resources.

[0003] Existing mulch film laying technologies are mostly surface covering methods. While this method can reduce evaporation to some extent, it cannot reduce infiltration losses from natural precipitation or artificial irrigation. Therefore, traditional mulch film laying methods cannot be widely promoted in arid regions.

[0004] In conclusion, there is an urgent need for a new technology that can effectively solve the planting problems in arid areas, so as to improve the efficiency of agricultural planting in arid areas and promote agricultural development in arid regions. Summary of the Invention

[0005] To overcome the problems existing in related technologies, the present invention provides a mulch film structure for improving water resource utilization efficiency in arid regions.

[0006] According to a first aspect of the present invention, a mulch film structure for improving water resource utilization efficiency in arid regions is provided, the mulch film structure comprising:

[0007] Several consecutively installed plastic film mulches;

[0008] The mulch film includes an underground anti-seepage section and an above-ground anti-evaporation section. The underground anti-seepage section and the above-ground anti-evaporation section are connected, and the connection point is used for planting plants. The above-ground evaporation section of the previous mulch film and the underground anti-seepage section of the next mulch film enclose each other to form a water-retaining space. The water in the water-retaining space can permeate to the roots of the plants through the connection point to provide water for the plants.

[0009] In some exemplary embodiments of the present invention, based on the foregoing scheme, the underground anti-seepage part and the above-ground anti-evaporation part are integrally formed.

[0010] In some exemplary embodiments of the present invention, based on the foregoing scheme, the above-ground anti-evaporation portion is in contact with the surface soil matrix and is configured as a centrally raised ridge structure.

[0011] In some exemplary embodiments of the present invention, based on the aforementioned scheme, the above-ground anti-evaporation portion of the preceding mulch film, on the side away from its underground anti-seepage portion, is bent at the connection point of the following mulch film to fit into the underground anti-seepage portion of the following mulch film, with the bending direction being the same as the extension direction of the underground anti-seepage portion of the following mulch film.

[0012] In some exemplary embodiments of the present invention, the mulch film is arranged in an array based on the foregoing scheme.

[0013] In some exemplary embodiments of the present invention, based on the foregoing scheme, both the rows and columns of the array are used for planting plants.

[0014] According to a second aspect of the present invention, a method for planting plants is provided, comprising:

[0015] Divide the land into arrays;

[0016] Laying out the above-mentioned mulch film structure to improve water resource utilization efficiency in arid regions.

[0017] According to a third aspect of the present invention, a sand-fixing barrier is provided, comprising:

[0018] Based on the above-mentioned mulch film structure used to improve water resource utilization efficiency in arid regions;

[0019] In the aforementioned mulch structure, the water-retaining space of each mulch film is used to wrap the sand body, and the two ends of each mulch film and the connection points are used to plant sand-fixing plants.

[0020] According to a fourth aspect of the present invention, a mulch film laying device is provided for laying a mulch film structure as described above for improving water resource utilization efficiency in arid regions.

[0021] The technical solutions provided by the embodiments of the present invention may include the following beneficial effects:

[0022] In this embodiment of the invention, the underground anti-seepage part can effectively prevent water from seeping into the deep underground layers, reducing the waste of water resources; the above-ground anti-evaporation part 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. In addition, the existence of water-retaining space can store natural precipitation or artificial water replenishment, and the water in the water-retaining space can permeate to the plant roots through the connection, providing a continuous water source for plant growth, ensuring that plants can obtain sufficient water supply in arid environments, thereby improving the survival rate and growth rate of plants in arid areas.

[0030] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0031] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0032] Although relative terms such as "up" and "down" are used in this invention to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the icon's arrangement is flipped so that it is upside down, the component described as "up" will become the component described as "down". Other relative terms such as "high", "low", "top", "bottom", "front", "back", "left", and "right" also have similar meanings. When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0033] According to a first aspect of the embodiments of the present invention, reference is made to Figure 1As shown, a mulch film structure for improving water resource utilization efficiency in arid regions is provided, the mulch film structure comprising:

[0034] Several consecutively installed plastic film mulches;

[0035] The mulch 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 point 3 is used for planting plants. The above-ground evaporation part of the previous mulch film and the underground anti-seepage part 1 of the next mulch film enclose each other to form a water-retaining space 4. The water in the water-retaining space 4 can permeate to the roots of the plants through the connection point 3 to provide water for the plants.

[0036] The underground anti-seepage part 1 can effectively prevent water from seeping into the deep underground layers, 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 humid local environment for plants and reducing the stress of drought on plants.

[0037] The existence of the water-retaining space 4 can store natural precipitation or artificial water replenishment, and the water in the water-retaining space 4 can permeate to the plant roots through the connection 3, providing a continuous water source for plant growth, ensuring that the plant can obtain sufficient water supply in arid environments, thereby improving the survival rate and growth rate of plants in arid areas.

[0038] The mulch film structure of this invention, combined with plant cultivation, can also play a certain role in sand fixation, reducing wind and sand erosion of soil in arid regions and helping to maintain the ecological balance of arid areas. Furthermore, as the plants grow and reproduce, they can help improve the ecological environment of arid regions, providing suitable conditions for the survival and growth of other organisms in the area, and promoting the restoration and development of the arid region's ecosystem.

[0039] In some implementations, the underground anti-seepage component 1 and the above-ground anti-evaporation component 2 can be installed separately. This way, if underground soil conditions change or the anti-seepage component is damaged, the underground anti-seepage component 1 can be replaced individually without replacing the entire mulch film structure. Similarly, if the performance of the above-ground anti-evaporation component 2 deteriorates due to prolonged exposure to wind and sun, it can also be replaced separately, improving the flexibility and sustainable use of the mulch film structure.

[0040] However, in arid regions, harsh natural conditions such as strong winds and sandstorms may be encountered. To enhance both seepage prevention and evaporation prevention while improving the stability of the mulch film structure, in this embodiment of the invention, the underground seepage-proof portion 1 and the above-ground evaporation-proof portion 2 are integrally formed.

[0041] In this way, the underground anti-seepage section 1 and the above-ground anti-evaporation section 2 are tightly and seamlessly connected. On the one hand, this avoids the problem of water leakage or accelerated evaporation that might occur due to a loose connection between the two parts, thus enhancing their anti-seepage and anti-evaporation effects. On the other hand, this structure can better resist external impacts, is less prone to separation or damage, and ensures that the mulch film structure functions stably for a long time, continuously providing a good moisture environment for plant growth. Moreover, the one-piece molding design reduces manufacturing processes and complexity, improves production efficiency, and lowers production costs. It is also more convenient and faster during installation, effectively reducing construction difficulty and time costs, which is conducive to large-scale application in arid regions.

[0042] Considering the water collection effect, in some exemplary embodiments of the present invention, the above-ground anti-evaporation part 2 is in contact with the surface soil matrix and is configured as a centrally raised ridge structure.

[0043] This design allows rainwater or irrigation water to flow down the sides of the ridge structure and collect in the planting area, increasing the time water stays on the surface and the amount collected, thus providing more usable water resources for the plants. Furthermore, the relatively high top of the ridge structure reduces the area of ​​direct sunlight reaching the soil surface, thereby slowing down water evaporation. Simultaneously, the relatively low sides of the ridge structure create shaded areas, further reducing water loss through evaporation and improving water resource utilization efficiency.

[0044] In addition, the ridge structure makes the planting area more regular, which facilitates field management operations such as weeding, fertilization, and pest and disease control. It also facilitates the layout of irrigation and drainage systems, thereby improving the efficiency and management level of agricultural production.

[0045] 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 preceding mulch film is bent at the connection point 3 of the following mulch film to fit with the underground anti-seepage portion 1 of the following mulch film, and the bending direction is the same as the extension direction of the underground anti-seepage portion 1 of the following mulch film.

[0046] In this way, since the bending direction is the same as the extension direction of the underground anti-seepage part 1 of the next mulch film, the water can be guided to flow more smoothly into the water-retaining space 4, which can not only provide a continuous water supply for the plant roots, but also help to avoid the disorderly flow of water on the ground surface, reducing water waste and loss.

[0047] The above-ground anti-evaporation portion 2 of the previous mulch film is bent at the connection point 3 of the next mulch film and adhered to the underground anti-seepage portion 1 of the next mulch film. This makes the connection between adjacent mulch films tighter. This tight adhesion can effectively reduce the possibility of water leakage from the connection point 3, enhance the sealing of the entire mulch film structure, ensure that the water-retaining space 4 can better store water, and improve the efficiency of water resource utilization. On the other hand, it can improve the overall stability of the mulch film structure, so that the entire mulch film structure can better resist the impact of severe weather in arid areas, prevent the mulch film from being lifted or damaged, and thus improve the service life of the mulch film structure.

[0048] In arid regions, land resources are often limited. To maximize the planting area on limited land while facilitating maintenance and management, some implementation methods refer to... Figure 1 As shown, the mulch film can be designed to be arranged in an array.

[0049] The array arrangement of plastic film not only allows for more rational planning of land space and full utilization of every piece of land resource, but also facilitates the management and maintenance of the film. For example, it enables orderly irrigation, fertilization, and pest and disease control. If a problem occurs in a certain area, it can be quickly located and resolved, reducing the impact on the entire planting area.

[0050] The water-retaining spaces 4 are more regularly and evenly distributed across the land, helping to balance water storage and supply throughout the planting area, preventing localized over- or under-watering, improving water resource utilization efficiency, and creating a more stable water environment for plant growth. Furthermore, the neat array arrangement makes the planting area look more aesthetically pleasing and standardized, enhancing the overall image of agricultural production.

[0051] In arid regions, land resources are precious, and efforts are being made to improve land utilization. In some implementation methods, reference is made to... Figure 2 As shown, both the rows and columns of the array are used for planting plants.

[0052] This allows for the full utilization of every inch of land, enabling the planting of more vegetation. This means better soil stabilization and prevention of soil erosion, while also increasing oxygen release and carbon dioxide absorption, thus improving the microclimate and ecological environment in arid regions. Furthermore, plant roots can improve soil structure and enhance the soil's water and fertilizer retention capacity.

[0053] Furthermore, proper spacing and layout of plants can create a favorable micro-ecological environment. For example, taller plants can provide some shade for shorter plants, reducing water evaporation; planting different types of plants together can attract more beneficial insects and microorganisms, promoting ecological balance and thus benefiting plant growth and development.

[0054] According to a second aspect of the embodiments of the present invention, reference is made to Figure 3 As shown, a plant cultivation method is provided, including:

[0055] S310: Divide the land into arrays;

[0056] S320: Laying the above-mentioned mulch film structure to improve water resource utilization efficiency in arid regions.

[0057] This invention divides land into arrays, making land planning more organized, fully utilizing every piece of land, and avoiding land waste. Laying the aforementioned mulch film structure in each area of ​​the array allows for planting throughout the entire land area, greatly increasing the arable area and enhancing the land's productivity potential.

[0058] The mulch film structure includes an underground anti-seepage section 1 and an above-ground anti-evaporation section 2, which can effectively prevent water leakage and evaporation loss. The water-retaining space 4 is designed to store natural precipitation or artificial water replenishment, and the water can permeate to the plant roots through the connection 3, providing a continuous water supply for the plants.

[0059] The protective effect of mulch film 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, improving plant survival rate and growth rate.

[0060] In arid regions, this planting method can help stabilize sand and conserve soil through plant growth and mulch, reducing soil erosion and wind erosion.

[0061] According to a third aspect of the present invention, a sand-fixing barrier is provided, comprising:

[0062] Based on the above-mentioned mulch film structure used to improve water resource utilization efficiency in arid regions;

[0063] In the above-mentioned mulch structure, the water-retaining space 4 of each mulch film is used to wrap the sand body, and the two ends of each mulch film and the connection 3 are used to plant sand-fixing plants.

[0064] The water-retaining space 4 in the mulch film structure is used to wrap the sand, effectively fixing the sand and preventing it from being blown away by the wind. The presence of the water-retaining space 4 can reduce the evaporation of moisture from the sand surface, maintain the moisture content of the sand, and thus increase the stability of the sand.

[0065] The ends and joints of the mulch film are used to plant sand-fixing plants. The roots of these plants can penetrate deep into the sand, further stabilizing it. Simultaneously, the growth of these plants improves soil structure, increases soil fertility, provides a habitat for other organisms, and promotes ecosystem restoration.

[0066] The mulch film structure can be made with low-cost materials, and the sand-fixing plants can be native species suitable for the local climate and soil conditions, reducing planting costs. At the same time, the maintenance cost of the sand-fixing barrier is also low, requiring only regular watering and fertilization.

[0067] The growth of sand-fixing plants can improve soil structure, increase soil fertility, provide a living environment for other organisms, and promote the restoration 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, and climate regulation, thus promoting the sustainable development of the local economy.

[0068] The sand-fixing barrier also has the aforementioned technical effects of the mulch film structure used to improve water resource utilization efficiency in arid regions, which will not be elaborated upon in this invention.

[0069] According to a fourth aspect of the present invention, a mulch film laying device is provided for laying a mulch film structure as described above for improving water resource utilization efficiency in arid regions.

[0070] Compared to manual laying, mulch film laying equipment significantly improves laying speed and efficiency. This equipment precisely controls the laying position and direction of the mulch film, ensuring a tight fit at the joints 3, forming an effective water-retaining space 4. Simultaneously, it ensures the adhesion between the mulch film and the soil, improving the seepage prevention effect of the underground anti-seepage section 1 and the evaporation prevention effect of the above-ground anti-evaporation section 2. Furthermore, the equipment applies uniform tension to the mulch film during laying, preventing problems such as loosening and wrinkling, ensuring the flatness and stability of the mulch film, and extending its service life. It also reduces the intensity of manual labor; operators only need to perform simple operations to complete the mulch film laying work, greatly reducing labor costs and labor intensity.

[0071] Other embodiments of the invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. 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. The specification and examples are to be considered exemplary only, and the true scope and spirit of the invention are indicated by the claims.

[0072] It should be understood that the present invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of the invention is limited only by the appended claims.
