Description

Technical Field

[0001] The invention relates to the technical field of wind and sand control, and in particular to a method for controlling sand using low-coverage shrubs and trees. Background Art

[0002] Land desertification and sandification lead to soil erosion, devour human living space, restrict economic sustainable development, and seriously threaten ecological security. my country has a large area of ​​desertified land and serious harm. Since the 1960s, following the principle of "high density, good sand control effect", large-scale sand prevention and control projects have been carried out. However, the sand-fixing forest has experienced large-scale decline and death of young and middle-aged forests, resulting in huge losses. For this reason, a low-coverage sand control method was proposed, with the goal of preventing wind and fixing sand and repairing degraded land, from improving water utilization, vegetation stability and accelerating restoration. Taking speed as the starting point, and under the premise of controlling the forest coverage at 15% to 25%, we will create a sand-fixing forest with 15% to 25% of the land occupied by artificial afforestation, leaving 75% to 85% of the land as a natural vegetation restoration zone. While ensuring the complete fixation of the quicksand and the healthy growth of trees, we will form a complex layer of trees, shrubs and grasses that can promote the rapid restoration of soil and vegetation, forming a low-coverage sand prevention and control system. Low-coverage sand control has made great breakthroughs in sand prevention and control, but how to improve the survival rate of seedlings in the early stage of planting is still a problem.

[0003] The Chinese patent CN116058224A discloses a greening method for preventing and controlling sand. The invention sets green seedlings in the center of a sand barrier. In the early stage of planting the seedlings, the outer sand barrier wrapped around the seedlings can protect the seedlings and increase their survival rate.

[0004] However, as seedlings for sand management, in order to better absorb moisture from the sand, their roots are usually longer, and deeper planting pits are required during the transplant process. Traditional planting pits undoubtedly make the sand softer during the digging process, which causes more serious sand flow near the seedlings, resulting in a decrease in the survival rate of the seedlings. In addition, this method of digging pits for planting undoubtedly increases a lot of manpower and material costs, resulting in a decrease in planting efficiency. Summary of the invention

It ensures the water balance of the sand-fixing forest, reduces interception consumption and surface evaporation, improves water use efficiency, and uses the long life of trees and shrubs to achieve natural vegetation restoration and soil development.

[0019] (4) The method for controlling sand with low-coverage shrubs and trees protects the roots of tree seedlings when they are inserted into the sand by setting a casing, thereby reducing the wear of the roots of the tree seedlings by the sand, thereby improving the survival rate of the tree seedlings after transplantation.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the description of the present invention, it is necessary to understand that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0025] Embodiment 1: See also Figure 1-Figure 11 The embodiment of the present invention provides a technical solution: a method for controlling sand using low-coverage shrubs and trees, comprising the following steps: S1. Lay 1m*1m grass grids 30 on the sand to achieve a preliminary sand fixation effect, reduce the damage of wind and sand to the tree belt 26 and the shrub belt 27, and improve the survival rate of seedlings; S2. Planting tree seedlings using transplanting equipment, preferably elm seedlings, and planting the trees at the intersection of the grass grid 30 to avoid serious sand flow in the surrounding sand after the tree seedlings are planted, so that every 1-3 rows of trees form a tree belt 26, the distance between two adjacent rows of tree belts 26 is 15m, and the spacing between plants in the same tree belt 26 is 2m*2m; S3, two rows of shrubs are planted on both sides of the tree belt 26, preferably Caragana korshinskii, and two adjacent rows of shrubs form a shrub belt 27, and the spacing between plants in the same shrub belt 27 is 1m*1m; S4, the tree belt 26 and the adjacent shrub belt 27 form a sand-fixing protection belt. A natural recovery belt 31 is set between two adjacent sand-fixing protection belts. The width of the natural recovery belt 31 is 10m. The tree belt 26 and the shrub belt 27 are combined to form a sand-fixing protection belt, which completely fixes the quicksand and realizes the wind-blocking and low-covering sand control of the belt, ensuring the water balance of the sand-fixing forest, reducing interception consumption and surface evaporation, and improving water use efficiency. The long life of trees and shrubs is used to achieve natural vegetation restoration and soil development. This is an active belt for the transfer and exchange of matter, energy and information at the interface between organisms and between organisms and the environment in the ecosystem. It has an ecological process and ecological benefits with a good interface, which is conducive to promoting the rapid restoration of natural vegetation and the process of soil development, and improving the biological productivity of sand-fixing composite vegetation; S5. A ditch 28 is opened in the middle of the natural recovery zone 31 for storing water during rainfall and for artificial irrigation during severe drought. Sand retaining belts 29 are set on both sides of the ditch 28 to prevent quicksand from flowing into the ditch 28. Preferably, the sand retaining belt 29 is a double-layer net structure with dead grass and wood interspersed between the double-layer nets to form a wall-shaped structure with a high degree of integrity, thereby preventing quicksand from entering the ditch 28 and serving as another barrier to block the wind on the sand.

[0026] like Figure 3-Figure 11As shown, the transplanting device in S2 includes a sleeve 1 and pedals 3 fixed on both sides of the sleeve 1, and also includes a notch groove 2. The notch groove 2 is opened on the sleeve 1 along the axial direction of the sleeve 1, so that the sleeve 1 forms an incomplete tubular structure, so that the top view of the sleeve 1 presents a "C" shape structure. In order to better wrap the tree seedlings, the side of the sleeve 1 relative to the notch groove 2 can also be set to a hinge connection, so that the sleeve 1 has the ability to open and close, and the tree seedlings can enter or exit the sleeve 1 through the notch groove 2, so as to facilitate the user's operation.

[0027] In order to facilitate the insertion of the sleeve 1 into the sand and fix the roots of the tree seedlings, the transplanting equipment provided in this embodiment also includes a clamping assembly, which is arranged at the lower end of the sleeve 1, and the clamping assembly can be opened and closed to clamp or detach the roots of the tree seedlings. When the clamping assembly is closed, its lower end forms a conical structure for insertion into the sand.

[0028] It should be noted in the present scheme that, due to the low water content in the sand, the root systems of plants surviving in the sand are often more developed, so as to insert their own roots into deeper sand and absorb moisture inside the sand. Therefore, the root systems of tree seedlings used for sand management need to be longer and more developed, which leads to the need to dig deeper pits during traditional pit-digging transplantation, which not only increases a lot of manpower and material costs, but also undoubtedly makes the sand softer during the pit-digging process, which causes more serious quicksand near the seedlings, thereby causing a decrease in the survival rate of the seedlings. For this reason, the present embodiment directly buries the roots of the seedlings deep into the ground by inserting them into the ground, so that the roots of the tree seedlings are straighter and deeper inside the sand, without the need to dig pits, to prevent the sand around the seedlings from becoming softer due to pit digging, thereby improving the survival rate of the seedlings after transplantation, and greatly reducing the output of manpower and material resources, and improving the transplantation efficiency.

[0029] like Figure 5-Figure 10 As shown, the clamping assembly provided in this embodiment includes a ground-inserting blade 5, which is a conical surface structure and is movably arranged at the lower end of the sleeve 1. The ground-inserting blade 5 is evenly arranged along the lower end of the sleeve 1, and the lower end of the ground-inserting blade 5 moves toward the axis of the sleeve 1 to close the clamping assembly. After closing, the ground-inserting blade 5 forms a conical structure to facilitate the insertion of the sleeve 1 into the sand. The lower end of the ground-inserting blade 5 turns away from the axis of the sleeve 1 to unfold the clamping assembly. When unfolded, the ground-inserting blade 5 is parallel to the sleeve 1, which is conducive to the extraction of the sleeve 1 from the sand, and can also enable the clamping assembly to unfold and release the roots of the tree seedlings to prevent the clamping assembly from taking out the seedling roots when leaving the sand.

[0030] In order to prevent the clamping force of the clamping assembly from being too strong and damaging the root system of the seedling, the clamping assembly provided in this embodiment also includes an inner lining plate 6, which is fixed to the inner side of the ground-inserting blade 5, and its main function is to provide support. A hollow hose 13 is fixed to the inner side of the inner lining plate 6 close to the axis of the sleeve 1. The deformation of the hollow hose 13 can realize flexible clamping of the roots of the tree seedlings, thereby avoiding damage to the roots of the tree seedlings and improving the survival rate of the tree seedlings after transplantation.

[0031] like Figure 6-Figure 11 As shown, in order to facilitate the control of the movement of the ground-inserting blade 5, a transmission plate 15 is fixed to the upper end of the inner lining plate 6 on the inner side of the ground-inserting blade 5 provided in this embodiment, and a wedge-shaped groove 17 is provided on the upper surface of the transmission plate 15. In addition, a connecting lining plate 4 is installed at the lower end of the sleeve 1, and the connecting lining plate 4 is adapted to the sleeve 1. Its top view is also "C"-shaped, and the lower end of the connecting lining plate 4 is connected to the middle section of the transmission plate 15. It should be noted that the advantage of the shaft connection in this solution is greater than that of the bearing connection. The reason is that the gravel inside the sand will penetrate into the bearing, resulting in a significant decrease in the bearing rotation effect. The advantage of the shaft connection is that its tightness is greater than that of the bearing, thereby reducing the entry of sand and gravel, and connecting grooves 18 are evenly spaced on the inner side of the connecting liner 4, and a limit pressure block 16 is slidably installed on the inner side of the connecting groove 18. The limit pressure block 16 is an inverted "L"-shaped structure, and the lower end of the limit pressure block 16 is adapted to the wedge-shaped groove 17. Through the sliding connection between the limit pressure block 16 and the connecting groove 18, the lower end of the limit pressure block 16 can be raised and lowered, thereby controlling the clutch of the limit pressure block 16 and the wedge-shaped groove 17, so as to drive the transmission plate 15 to move, and then control the movement of the ground-inserting blade 5.

[0032] like Figure 3-Figure 5 As shown, for the convenience of user operation, a connecting plate 9 is installed at the upper end of the sleeve 1, and a lifting rod 10 is symmetrically fixed to the upper end of the connecting plate 9. The lifting rods 10 are symmetrically arranged, which is conducive to the hanging of the stems and leaves of the tree seedlings, so as to achieve the fixation of the tree seedlings and avoid manual support. Handles 11 are installed on the outer upper ends of the two lifting rods 10, so that the user can carry the handles 11 and step on the pedal 3, which is more conducive to the user's force application.

[0033] like Figure 3 and Figure 4 As shown, in order to reduce the entry of sand and gravel into the interior of the clamping assembly, a sand-proof cloth belt 7 is fixed to the lower end of the outer side of the sleeve 1, and the lower end of the sand-proof cloth belt 7 is fixedly connected to the upper end of the outer side of the ground-inserting blade 5. The sand-proof cloth belt 7 has the ability to be deformed and does not affect the movement of the ground-inserting blade 5. In addition, the existence of the sand-proof cloth belt 7 can reduce the entry of sand and gravel into the interior of the clamping assembly and improve the stability of the clamping assembly when it is working.

[0034] like Figure 3-Figure 11As shown, in order to facilitate manual control of the ground-inserting blade 5, the sleeve 1 provided in this embodiment is fixedly connected to the connecting liner 4, so that the distance between the sleeve 1 and the connecting liner 4 is immutable, and the sleeve 1 is movably connected to the connecting plate 9, which is conducive to adjusting the distance between the sleeve 1 and the connecting plate 9. A driving member for driving the transmission plate 15 to rotate is provided on the sleeve 1. The driving member includes a connecting slide rod 14, which is arranged in the sleeve 1, and the connecting slide rod 14 is slidably connected to the sleeve 1 along the axial direction of the sleeve 1. The upper end of the connecting slide rod 14 passes through the sleeve 1 and is fixedly connected to the connecting plate 9, and a reset spring 12 is installed on the outer side of the connecting slide rod 14 between the connecting plate 9 and the sleeve 1. The reset spring 12 is mainly used to drive the reset of the connecting plate 9 after the movement.

[0035] In addition, in order to enable the connecting slide rod 14 to move to drive the transmission plate 15 to move, the driving member provided in this embodiment also includes a first connecting rod 19, which is rotatably installed on one end of the transmission plate 15 close to the ground-inserting blade 5, and a second connecting rod 20 is rotatably installed on the other end of the first connecting rod 19, and the other end of the second connecting rod 20 is hinged to the connecting slide rod 14.

[0036] In this solution, the lifting rod 10 is manually controlled to move to drive the connecting plate 9 to move, thereby adjusting the distance between the connecting plate 9 and the casing 1. When the distance between the connecting plate 9 and the casing 1 is shortened, the connecting slide rod 14 moves downward, so that the angle between the first connecting rod 19 and the second connecting rod 20 becomes smaller, and the transmission plate 15 is further squeezed to move the lower end of the ground-inserting blade 5 toward the axis of the casing 1, so that the ground-inserting blade 5 is combined to form a conical structure, so as to better insert it into the sand. In addition, the ground-inserting blade 5 drives the inner lining plate 6 to make the hollow hose 1 3 are close to each other, and then the hollow hose 13 squeezes the root of the tree seedling to fix the root of the tree seedling, so that the sleeve 1 drives the root of the tree seedling to be inserted into the sand. When the distance between the connecting plate 9 and the sleeve 1 becomes longer, the connecting slide bar 14 moves upward, so that the angle between the first connecting rod 19 and the second connecting rod 20 becomes larger, so as to drive the transmission plate 15 to move, so that the lower end of the ground-inserting blade 5 moves away from the axial direction of the sleeve 1, so that the ground-inserting blade 5 is unfolded and the root of the tree seedling is released to prevent the clamping assembly from taking out the seedling root system when leaving the sand.

[0037] like Figure 4 As shown, in order to improve the stability of the connecting plate 9 when it moves, a sleeve 8 is fixed at the lower end of the connecting plate 9, and the sleeve 8 is slidably connected to the upper end of the outer side of the sleeve 1. The sliding connection between the sleeve 8 and the sleeve 1 improves the stability of the connecting plate 9 when it moves.

[0038] When in use (working), first insert the root of the tree seedling into the sleeve 1 from the notch groove 2, press the handle 11 downward so that the lifting rod 10 drives the connecting plate 9 downward, at this time, the return spring 12 is compressed, the distance between the connecting plate 9 and the sleeve 1 is shortened, and the connecting slide bar 14 moves downward, so that the angle between the first connecting rod 19 and the second connecting rod 20 becomes smaller, and the transmission plate 15 is further squeezed, so that the lower end of the ground-inserting blade 5 moves toward the axis of the sleeve 1, so that the ground-inserting blade 5 is combined to form a conical structure, so as to better insert it into the sand. In addition, the ground-inserting blade 5 drives the inner lining plate 6 to make the hollow hose 13 approach each other, and then the hollow hose 13 squeezes the root of the tree seedling, so as to fix the root of the tree seedling, so that the sleeve 1 drives the root of the tree seedling to be inserted into the sand. In this process, due to the action of gravity, the limiting pressure block 16 is at the lower end of the connecting slide groove 18, and the wedge-shaped groove 17 is squeezed by the transmission plate 15. The limit block 16 is moved to the upper end of the connecting slot 18 to realize the limit function to prevent the transmission plate 15 from excessive movement. After the roots of the tree seedlings are implanted in the sand, the handle 11 is pulled upward to lengthen the distance between the connecting plate 9 and the sleeve 1, the return spring 12 is relaxed, and the connecting slide bar 14 moves upward, so that the angle between the first connecting rod 19 and the second connecting rod 20 becomes larger, thereby driving the transmission plate 15 to move, so that the lower end of the ground-inserting blade 5 moves away from the axial direction of the sleeve 1, thereby allowing the ground-inserting blade 5 to unfold and release the roots of the tree seedlings to prevent the clamping assembly from taking out the seedling roots when leaving the sand. In this process, the transmission plate 15 drives the wedge-shaped groove 17 to move in a direction away from the limit block 16. At this time, the limit block 16 descends to the lower end of the connecting slot 18 under the action of gravity. During the whole process, the limit block 16 and the wedge-shaped groove 17 are always against each other, thereby ensuring the stability of the transmission plate 15 during movement.

[0039] Embodiment 2: like Figure 12-14 As shown, the difference between this embodiment and the first embodiment is that: in order to reduce the manual burden, the ground-inserting blade 5 can be automatically moved according to the situation of entering and exiting the sand. Specifically, the sleeve 1 is slidably connected to the connecting lining plate 4, and the sleeve 1 is fixedly connected to the connecting plate 9. The sleeve 1 is provided with a driving member for driving the transmission plate 15 to rotate. The driving member includes a first connecting rod 19, and the first connecting rod 19 is rotatably installed on one end of the transmission plate 15 close to the ground-inserting blade 5. The other end of the first connecting rod 19 is rotatably installed with a second connecting rod 20, and the other end of the second connecting rod 20 is hinged to the bottom of the sleeve 1 through a hinge seat 24.

[0040] The sand-breaking cone 21 is fixed to the outside of the ground-inserting blade 5 . The sand-breaking cone 21 is a tetrahedral structure, and a cavity is provided on the upper surface of the sand-breaking cone 21 .

[0041] In this solution, when the casing 1 is inserted into the sand, the casing 1 moves downward, and the ground-inserting blade 5 is subjected to the resistance of the sand, so that the connecting liner 4 moves upward relative to the casing 1, so that the limiting pressure block 16 is separated from the wedge-shaped groove 17, and the resistance of the sand squeezes the ground-inserting blade 5, so that the ground-inserting blade 5 moves toward the axis of the casing 1, so that the ground-inserting blade 5 gradually moves together to form a conical structure, which is convenient for insertion into the sand. When the casing 1 is pulled out of the sand, the casing 1 moves upward, and the connecting liner 4 slides downward inside the casing 1 due to gravity and the resistance of the sand, further driving the limiting pressure block 16 downward and pressurizing the wedge-shaped groove 17, so that the transmission plate 15 drives the ground-inserting blade 5 away from the axis of the casing 1, thereby realizing the expansion of the clamping assembly, so as to facilitate the separation of the casing 1 from the root of the tree.

[0042] In order to improve the stability of the connection between the connecting lining 4 and the sleeve 1, a limiting slider 23 is fixed at equal intervals on the outer side of the connecting lining 4 near the upper end, and a limiting groove 22 is provided at the lower end of the sleeve 1 for sliding connection with the limiting slider 23. The sliding connection between the limiting slider 23 and the limiting groove 22 improves the stability of the connecting lining 4 during movement.

[0043] When in use, first insert the root of the tree seedling into the sleeve 1 from the notch groove 2, place the root of the tree seedling on the hollow hose 13, and press the ground-inserting blade 5 against the surface of the sand. Gently press the handle 11 to make the lifting rod 10 push the sleeve 1 downward to ensure that the sleeve 1 moves downward but the ground-inserting blade 5 does not completely enter the sand. At this time, the end of the sleeve 1 will approach the upper end of the ground-inserting blade 5, so that the angle between the first connecting rod 19 and the second connecting rod 20 becomes smaller, and the transmission plate 15 is further squeezed to make the lower end of the ground-inserting blade 5 move toward the axis of the sleeve 1, so that the ground-inserting blade 5 is combined to form a conical structure, which is convenient for it to be inserted into the sand. In this process, the ground-inserting blade 5 drives the inner lining plate 6 to make the hollow hose 13 close to each other, thereby fixing the root of the tree seedling. Then press the handle 11 hard and step on the pedal 3 downward hard, so that the ground-inserting blade 5 drives the sleeve 1 to be inserted into the sand.

[0044] After the roots of the tree seedlings are placed in the sand, the handle 11 is pulled upward to move the sleeve 1 upward. Initially, the ground-inserting blade 5 is squeezed by the sand and does not expand outward. In this process, the sleeve 1 moves upward, and the connecting liner 4 is subjected to the resistance of the sand and its own gravity and slides to the lower end of the sleeve 1, thereby increasing the distance between the sleeve 1 and the connecting liner 4, and further increasing the angle between the first connecting rod 19 and the second connecting rod 20, so as to drive the transmission plate 15 to move, so that the lower end of the ground-inserting blade 5 moves away from the axial direction of the sleeve 1, thereby expanding the ground-inserting blade 5 and releasing the roots of the tree seedlings to prevent the clamping assembly from taking out the seedling roots when leaving the sand.

[0045] Embodiment three: like Fig.15 As shown, the difference between this embodiment and the first embodiment is that the first connecting rod 19 and the second connecting rod 20 are replaced with a flexible steel wire rope 25, and the lower end of the connecting slide rod 14 is connected to the end of the transmission plate 15 away from the wedge groove 17 through the flexible steel wire rope 25.

[0046] In this solution, it is necessary to rely on the lower end of the connecting slide rod 14 to abut against the transmission plate 15 to drive the transmission plate 15 to move, so that the transmission plate 15 drives the ground-inserting blade 5 to move toward the axial direction of the casing 1. When the ground-inserting blade 5 moves away from the axial direction of the casing 1, it can be pulled by the flexible steel wire rope 25, so that the connecting slide rod 14 drives the flexible steel wire rope 25 to be tightened, thereby driving the transmission plate 15 to move.

[0047] Compared with the first embodiment, since the connecting slide bar 14 and the transmission plate 15 are connected by the flexible steel wire rope 25, there is no need to worry about gravel entering the clamping assembly and affecting the shaft connection effect.
