Description

Technical Field

[0001] This invention generally relates to the field of ecological planting, and specifically to an ecological planting device suitable for saline soil areas. Background Technology

[0002] Saline soil is a widespread soil type globally, distributed across arid and semi-arid regions and coastal areas of every continent. It is estimated that saline soil covers approximately 10% of the total land area globally, exceeding 950 million hectares. In my country, saline soil is also widely distributed, covering approximately 36 million hectares, mainly concentrated in the Northwest, North China, Northeast, and coastal areas.

[0003] Saline soils contain excessive amounts of soluble salts (such as sodium chloride, sodium sulfate, and sodium carbonate) and exchangeable sodium ions, which severely deteriorates their physicochemical properties and causes multiple adverse effects on plant growth. Specifically, high salt concentrations lead to a significant increase in soil solution osmotic pressure, far exceeding the osmotic pressure of plant root cell sap. This makes it difficult for plant roots to absorb water from the soil, and even with high soil moisture content, plants will still wither due to "physiological drought." Simultaneously, excessive sodium ions damage the structure and function of plant cell membranes, interfere with intracellular enzyme activity, and inhibit key physiological metabolic processes such as photosynthesis and respiration, resulting in stunted plant growth, yellowing leaves, reduced fruit set, and even death. Furthermore, saline soils typically have poor soil structure, with poor aeration and permeability, which is detrimental to root respiration and extension, further exacerbating the difficulties in plant growth. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides an ecological planting device suitable for saline soil areas, comprising:

[0005] The planting box has an opening at the top and is buried in the saline soil layer;

[0006] Nutrient substrate is filled into the planting box, and plants are planted in the central area of ​​the nutrient substrate;

[0007] A water collection cover is installed in a ring around the center of the planting box, and includes a support frame and a cover covering the outside of the support frame.

[0008] The support frame, with its outer ring fixed within the saline soil layer and its inner ring fixed within the nutrient substrate, also includes...

[0009] Multiple support rods are provided to support the cover, with one end fixed to the outer ring area of ​​the support frame and the other end fixed to the inner ring area. These technical features ensure plant photosynthesis, provide essential soil nutrients and moisture, and guarantee successful vegetation growth in saline-alkali soil areas. A water collection cover located around the vegetation, covering part of the saline-alkali soil area, collects evaporating moisture from the soil and guides it through the cover to the nutrient substrate, thus ensuring normal plant growth within the planting box.

[0010] In some embodiments, the support rod includes

[0011] The extension section, one end of which is fixed in the saline soil and the other end extends upwards; it also includes...

[0012] The guide section has one end connected to the end of the extension section and the other end fixed inside the nutrient substrate. This ensures the coverage area of ​​the water collection hood over the saline soil layer, and through the guide section, directs water from higher points into the nutrient substrate, thus ensuring the orderly flow and collection of evaporated water into the planting box. Furthermore, the water collection hood not only guides external water sources but also collects water vapor from the covered saline soil layer.

[0013] In some embodiments, the support frame includes

[0014] An inner ring pipe is embedded within the nutrient substrate, and the end of the guide section is inserted into the inner ring pipe. This provides a fixed carrier for the support rod, ensuring the stability of the water collection hood's layout and the uniformity of the overall distribution of the hood, allowing water to accumulate evenly within the nutrient substrate.

[0015] In some embodiments, the end of the flow guide is provided with an external thread, and a limiting block is threadedly connected to the end of the flow guide. Thus, by connecting the limiting block to the threaded end of the flow guide, the separation of the flow guide from the inner ring pipe is restricted. On the other hand, the position of the limiting block can be fixed, the overall curvature of the flow guide can be adjusted, and the outline of the cover can be further adjusted, thereby adjusting the outline of the cover according to the actual conditions of the saline soil.

[0016] In some embodiments, a drainage mechanism is provided between the adjacent support rods to cause deformation of the cover, the drainage mechanism including...

[0017] The drainage rope has one end fixed in the saline soil and the other end inserted into the inner ring tube, with its main body abutting against the outside of the cover.

[0018] The drive motor is fixed inside the inner ring tube;

[0019] A spool is coaxially fixed to the output shaft of the drive motor, and the end of the drainage rope is fixed to the circumference of the spool. Therefore, due to the varying moisture content of the saline soil, workers can adjust the curvature of the hood by pulling the drainage rope, driven by the start of the drive motor, based on the area of ​​saline soil actually covered by the water collection hood. This further adjusts the concentration area of ​​water vapor, achieving regional water supply. Furthermore, because the drainage rope is located outside the hood, combined with the support rod inside, the hood is more firmly secured. As the drainage rope is pulled, it causes slippage between the guide section and the inner ring pipe, resulting in more uniform regional deformation of the hood and reducing the risk of excessive regional stress and structural damage.

[0020] In some embodiments, the surface of the planting box is covered with a one-way permeable membrane. This reduces water evaporation inside the planting box, and water collected externally can also enter the planting box through the one-way permeable membrane, further ensuring the nutrient supply to the vegetation.

[0021] In some embodiments, the inner ring arm of the inner ring tube is provided with an opening. This facilitates the mutual fixation of the limiting block and the guide portion of the support rod, as well as the fixation of the drainage rope.

[0022] In some embodiments, an outer ring tube is further included, with the end of the extension inserted into the outer ring tube and the end of the drainage rope fixed to the outer ring tube.

[0023] This improves the fixing efficiency of the support frame and also ensures the uniformity of the curvature distribution in each area after the cover is fixed.

[0024] In some embodiments, the planting box is equipped with an annular water-retaining trough filled with water, located inside the water collection hood. This creates a stable, humid environment within the water collection hood, ensuring adequate moisture for the nutrient substrate even in arid conditions.

[0025] It should be understood that the description in the Summary of the Invention is not intended to limit the key or essential features of the embodiments of this disclosure, nor is it intended to restrict the scope of this disclosure. Other features of this disclosure will become readily apparent from the following description. Attached Figure Description

[0033] The preferred embodiments (or implementation methods) of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] The following is for reference. Figures 1-5 This invention describes an ecological planting device suitable for saline soil areas.

[0035] Figure 1 A schematic diagram of the overall structure of an ecological planting device suitable for saline-alkali soil areas, according to an embodiment of the present invention, is shown. (Reference) Figure 1 As shown, an ecological planting device suitable for saline soil areas includes a planting box 1 buried inside the saline soil layer. The top of the planting box 1 is open and flush with the upper surface of the saline soil layer. The planting box 1 is filled with a nutrient substrate 2 that provides nutrients for plant growth. A water collection hood 3 is installed above the planting box 1. The water collection hood 3 is annular, with part of its area covering the periphery of the nutrient substrate 2 and part of its area covering the saline soil layer around the planting box 1. On the one hand, rainwater from the external environment can be guided towards the planting box 1 in the center by the water collection hood 3. On the other hand, water vapor evaporated from the saline soil layer covered by the water collection hood 3 will also be guided into the nutrient substrate 2 by the water collection hood 3, thereby ensuring the normal growth of the plants planted in the central area of ​​the nutrient substrate 2.

[0036] In some embodiments, the upper surface of the planting box 1 is covered with a one-way permeable membrane 11. The one-way permeable membrane 11 can be a polymer membrane, specifically a polyethersulfone one-way permeable membrane. It uses polyethersulfone polymer as the substrate, possessing chemical stability and high mechanical strength. Through molecular sieving, it allows small molecules to pass through while retaining large molecules (such as salts and organic matter). Alternatively, it can be a polyvinylidene fluoride hollow fiber membrane, which has the characteristics of being resistant to fouling and having high flux, ensuring unidirectional water flow. With the one-way permeable membrane 11 in place, water inside the planting box 1 is less likely to evaporate from the top space into the external environment, thus ensuring a stable humidity environment inside the planting box 1. Furthermore, rainwater from the external environment and liquids guided by the water collection membrane can also be guided into the nutrient substrate 2 through the one-way permeable membrane 11, thereby ensuring a sustained humidity environment inside the planting box 1.

[0037] In some embodiments, an annular water-retaining trough 12 is provided at the edge of the end of the planting box 1, which is filled with water. On the one hand, the water-retaining trough 12 is pressed against the edge of the one-way permeable membrane 11 to ensure the firmness of the one-way permeable membrane 11 covering the top area of ​​the planting box 1; on the other hand, the water-retaining trough 12 is located under the cover of the water collection cover 3, and the water in it slowly evaporates. In a dry environment, it can delay the loss of humidity in the planting box 1 and maintain the nutrient environment in the planting box 1 for a long time.

[0038] Figure 2 An exploded view of the water collection hood 3 in an ecological planting device suitable for saline-alkali soil areas, according to an embodiment of the present invention, is shown. (See reference) Figure 2 As shown, the moisture collection cover 3 includes a support frame 31 and a cover body 32 structure covering the outside of the support frame 31. The support frame 31 includes an inner ring pipe 311, an outer ring pipe 312 disposed outside the inner ring pipe 311, and support rods 313 connecting the inner ring pipe 311 and the outer ring pipe 312. Multiple support rods 313 are provided and evenly distributed along the annular direction of the inner ring pipe 311. Specifically, the inner ring pipe 311 is buried inside the nutrient substrate 2, while the outer ring pipe 312 is buried in the saline soil layer outside the planting box 1.

[0039] In some embodiments, the cover 32 may be a TPU film, which has a highly elastic structure, tear-resistant cavity, and resistance to repeated friction; moreover, it has a hydrophilic structure, so liquid water cannot penetrate it; furthermore, the material is lightweight per unit area, which does not easily burden the installation staff.

[0040] In some embodiments, the outer ring pipe 312 and the inner ring pipe 311 are coaxially arranged, thereby making the bending amplitude of the support rod 313 more uniform and the contour change of each region of the cover 32 more uniform. Furthermore, the water vapor evaporated in the saline soil layer is more evenly distributed in the nutrient matrix 2.

[0041] In some embodiments, the support rod 313 includes a long, straight extension 3131, one end of which is fixed to the outer ring tube 312, and the other end extends upward. The end of the extension 3131 is provided with an arc-shaped guide portion 3132. One end of the guide portion 3132 is fixed to the end of the extension 3131, and the other end extends towards the inner ring tube 311 and is inserted into the inner ring tube 311. This results in the support rod 313 forming an arc-shaped region that is higher on the outside and lower on the inside. Evaporated water vapor adheres to the inner wall of the cover 32, forming water droplets that flow towards the interior of the planting box 1 under gravity, thus collecting and guiding the water vapor.

[0042] Figure 3 A partial structural schematic diagram of the inner ring pipe 311 in an ecological planting device suitable for saline soil areas, according to an embodiment of the present invention, is shown. (See reference) Figure 3 As shown, the inner ring pipe 311 has a rectangular cross-section, with an open annular region facing the center to facilitate the operation and fixing of the end of the guide section 3132. The end of the guide section 3132 passes through the inner ring pipe 311, and external threads are formed on the periphery of the end of the guide section 3132. A limiting block 4 is threadedly connected to the end of the guide section 3132. The operator can adjust the bending amplitude of the guide section 3132 by adjusting the movement of the limiting block 4 along the length of the guide section 3132. Specifically, the bending amplitude of the guide section 3132 in different areas can be adjusted according to the growth of the plants in the nutrient substrate 2, thereby adjusting the tilt trend of the cover 32 and thus adjusting the area for preferential guidance of rainwater or water vapor.

[0043] Figure 4 This invention illustrates a schematic diagram of the drainage mechanism 5 in an ecological planting device suitable for saline soil areas, according to an embodiment of the present invention. Figure 5 A schematic diagram illustrating the connection relationship between the guide rope 51 and the cover 32 in an ecological planting device suitable for saline soil areas according to an embodiment of the present invention is shown. (See reference) Figure 4 and Figure 5As shown, a diversion mechanism 5 is also provided between adjacent support rods 313 to drive the support frame 31 to deform. The diversion mechanism 5 includes a diversion rope 51, one end of which is fixed to the outer ring pipe 312, and the other end is attached to the outside of the cover 32 and extends towards the inner ring pipe 311, passing through the inside of the inner ring pipe 311. A drive motor 52 is fixed inside the inner ring pipe 311, and a wire shaft 53 is coaxially fixed to the output shaft of the drive motor 52. The end of the diversion rope 51 is fixed to the periphery of the wire shaft 53 and wound around the wire shaft 53. As the drive motor 52 drives, the wire shaft 53 rotates, causing the diversion rope 51 to be pulled towards the inner ring pipe 311. As the diversion rope 51 tightens, the cover 32 is subjected to local pressure, thereby realizing the deformation of the local area of ​​the cover 32. It is easier to increase the curvature of the local area of ​​the cover 32 through the deformation of the cover 32, and further improve the accumulation of rainwater or water vapor in the area.

[0044] Furthermore, as the drainage rope 51 is pulled, it will cause the end of the guide section 3132 and the inner ring tube 311 to slide against each other, making the pressure on the area of ​​the cover 32 affected by the drainage rope 51 more uniform, and making it less likely to cause excessive local pressure on the cover 32 and damage to the cover 32.

[0045] In some embodiments, the drainage rope 51 can be a nylon rope with a diameter of 10mm or more. On the one hand, nylon material has a smooth surface and strong elasticity, and its wear resistance is better than that of natural fibers. During the process of pulling the drainage rope 51, it is not easy to rub against the surface of the cover 32. Moreover, the diameter of the drainage rope 51 is relatively thick, thereby increasing the contact area between it and the cover 32, reducing the local pressure between the drainage rope 51 and the cover 32, and further reducing the damage to the cover 32.

[0046] In the description of this specification, the terms "connection," "installation," and "fixing," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0047] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
