Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wind-sand control, in particular to a low-coverage shrub and tree sand control method. BACKGROUND

[0002] Land desertification and sandification lead to water and soil loss, encroach on human living space, restrict sustainable economic development, and seriously threaten ecological security. China has a large area of desertification land and serious damage. Since the 1960s, large-scale sand prevention and control projects have been carried out in accordance with the principle of "high density, good sand control effect". However, the middle and young aged forest of sand fixation forest has appeared in large areas, and the phenomenon of decay and death has caused huge losses. Therefore, a low-coverage sand control method is proposed to prevent wind and sand, and to repair degraded land. The method aims to improve water use efficiency, vegetation stability, and accelerate the repair speed. Under the premise of controlling the forest coverage at 15% to 25%, the method creates a sand fixation forest with 15% to 25% of artificial afforestation and 75% to 85% of land left for natural vegetation restoration. Under the condition of ensuring complete sand fixation and healthy growth of trees, a complex vegetation of trees, shrubs, and grasses is formed to promote rapid soil and vegetation restoration, forming a low-coverage sand prevention and control system. The low-coverage sand control method has made great breakthroughs in sand prevention and control. However, how to improve the survival rate of seedlings in the early stage of planting is still a problem.

[0003] In CN116058224A, a sand prevention and control greening method is disclosed. The invention sets seedlings in the center of the sand barrier and protects the seedlings by wrapping the surrounding sand barrier in the early stage of seedling planting, which increases the survival rate of seedlings.

[0004] However, as seedlings for sand control, their root systems are usually long to better absorb water from the sand interior. The planting hole requires a deeper depth during transplantation. The traditional planting hole makes the sand more loose during the digging process, which causes more serious sand flow around the seedlings, resulting in a decrease in seedling survival rate. In addition, this planting method undoubtedly increases the cost of manpower and resources, leading to a decrease in planting efficiency. SUMMARY

[0043] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described in the description of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0044] In the description of the present application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery" and the like indicate the orientation or positional relationship, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the referred component or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0045] Embodiment one:

[0046] Please refer to Figures 1-11 The embodiment of the present application provides a technical solution: a low-coverage shrub and tree sand control method, comprising the following steps:

[0047] S1, laying 1m*1m grass checkerboard 30 on the sand land to achieve the effect of preliminary sand fixation, reducing the damage of wind sand to the tree belt 26 and the shrub belt 27, and improving the survival rate of seedlings;

[0048] S2, transplanting equipment is used to plant tree seedlings, and the tree seedlings are preferably elm seedlings, the tree seedlings are planted at the intersection of the grass checkerboard 30 to avoid the serious sand flow around the tree seedlings after planting, so that every 1-3 rows of trees form a tree belt 26, the distance between the adjacent two rows of tree belts 26 is 15m, and the plant spacing between the same tree belt 26 is 2m*2m;

[0049] S3, two rows of shrubs are planted on both sides of the tree belt 26, the shrubs are preferably caragana, the adjacent two rows of shrubs form a shrub belt 27, and the plant spacing between the same shrub belt 27 is 1m*1m;

[0050] S4, the tree belt 26 and the adjacent shrub belt 27 form a sand-fixing protection belt. A natural restoration belt 31 is set between two adjacent sand-fixing protection belts. The width of the natural restoration belt 31 is 10m. The combination of tree belt 26 and shrub belt 27 forms a sand-fixing protection belt, which completely fixes the shifting sand, realizes wind-blocking and low-coverage sand control, ensures the water balance of the sand-fixing forest, reduces interception and consumption, surface evaporation, and improves water use efficiency. The long lifespan of trees and shrubs is used to realize the natural restoration of vegetation and soil development. This is an active zone for the transfer and exchange of matter, energy and information between organisms and between organisms and the environment in the ecosystem. It has good ecological processes and ecological benefits, which is conducive to promoting the rapid restoration of natural vegetation and soil development, and improving the biological productivity of sand-fixing composite vegetation.

[0051] S5. Ditches 28 are dug in the middle of the natural restoration zone 31 for water storage during rainfall and artificial irrigation during severe drought. Sand-blocking belts 29 are set on both sides of the ditch 28 to prevent flowing sand from flowing into the ditch 28. Preferably, the sand-blocking belts 29 are double-layered net structures with dead grass and wood sandwiched between the double layers to form a wall-like structure with high integrity, thereby preventing flowing sand from entering the ditch 28 and serving as another barrier against wind in the sandy area.

[0052] like Figures 3-11 As shown, the transplanting device in S2 includes a sleeve 1 and pedals 3 fixed to both sides of the sleeve 1, as well as a notch 2. The notch 2 is opened on the sleeve 1 along the axial direction of the sleeve 1, so that the sleeve 1 forms a non-complete tubular structure, so that the top view of the sleeve 1 presents a "C" shape. In order to better wrap the sapling, the side of the sleeve 1 opposite to the notch 2 can also be set as a hinge connection, so that the sleeve 1 has the ability to open and close, and the sapling can enter or leave the sleeve 1 through the notch 2, so as to facilitate the operation of the user.

[0053] To facilitate the insertion of the sleeve 1 into the sandy soil and to fix the roots of the tree seedlings, the transplanting device provided in this embodiment also includes a clamping component. The clamping component is located at the lower end of the sleeve 1 and can be opened and closed to clamp or detach from the roots of the tree seedlings. When the clamping component is closed, its lower end forms a conical structure for insertion into the sandy soil.

[0054] It needs to be explained in the scheme that because the water content in the sand is low, the roots of the plants surviving in the sand are often more developed to insert their roots into the deeper sand to absorb the water inside the sand, therefore, the roots of the tree seedlings for sand treatment need to be longer and more developed, which leads to the need of digging deeper pits in the traditional transplanting by digging pits, which not only increases the cost of manpower and material resources, but also makes the sand more loose in the process of digging pits, which causes the drifting sand around the seedlings to be more serious, thereby reducing the survival rate of the seedlings. Therefore, the embodiment directly buries the roots of the seedlings into the ground by using the insertion method, so that the roots of the tree seedlings are straighter and deeper in the sand, without the need of digging pits, to prevent the sand around the seedlings from being more loose due to digging pits, thereby improving the survival rate of the seedlings after transplanting, and greatly reducing the output of manpower and material resources and improving the transplanting efficiency.

[0055] As shown in Figures 5-10 The clamping assembly provided by the embodiment includes an insertion blade 5, which is a conical surface structure and movably arranged at the lower end of the sleeve 1. The insertion blade 5 is uniformly arranged along the lower end of the sleeve 1, and the lower end of the insertion blade 5 moves towards the axis of the sleeve 1 to close the clamping assembly. After closing, the insertion blade 5 forms a conical structure to facilitate the insertion of the sleeve 1 into the sand. The lower end of the insertion blade 5 moves away from the axis of the sleeve 1 to expand the clamping assembly. When expanded, the insertion blade 5 is parallel to the sleeve 1, which is beneficial to the extraction of the sleeve 1 from the sand and the expansion of the clamping assembly to release the roots of the tree seedlings to prevent the clamping assembly from taking out the roots of the seedlings when it is separated from the sand.

[0056] To prevent the clamping assembly from damaging the roots of the seedlings due to excessive clamping force, the clamping assembly provided by the embodiment further includes an inner lining plate 6 fixed to the inner side of the insertion blade 5, which mainly plays a supporting role. The inner lining plate 6 has a hollow hose 13 fixed to the side close to the axis of the sleeve 1 inside. The flexible clamping of the roots of the tree seedlings can be achieved by deforming the hollow hose 13, which avoids damaging the roots of the tree seedlings and improves the survival rate of the tree seedlings after transplanting.

[0057] As shown in Figures 6-11As shown, in order to conveniently control the activity of the ground insertion blade 5, the inner side of the ground insertion blade 5 in the embodiment is provided with a transmission plate 15 fixed at the upper end of the inner lining plate 6, the upper surface of the transmission plate 15 is provided with a wedge-shaped groove 17, in addition, a connecting lining plate 4 is installed at the lower end of the sleeve 1, the connecting lining plate 4 is adapted to the sleeve 1, the top view is also "C" shape, and the lower end of the connecting lining plate 4 is connected with the middle shaft of the transmission plate 15. It should be noted that the advantages of the shaft connection are greater than those of the bearing connection in the present scheme, because the sand and gravel in the sand will be immersed in the bearing, which will greatly reduce the rotating effect of the bearing. 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 the inner side of the connecting lining plate 4 is provided with a connecting sliding groove 18 at equal intervals, the inner side of the connecting sliding groove 18 is slidably provided with a limiting block 16, the limiting block 16 is in the shape of an inverted "L", and the lower end of the limiting block 16 is adapted to the wedge-shaped groove 17. Through the sliding connection between the limiting block 16 and the connecting sliding groove 18, the lower end of the limiting block 16 can be lifted, so as to control the engagement and disengagement of the limiting block 16 and the wedge-shaped groove 17, so as to drive the transmission plate 15 to move, thereby controlling the movement of the ground insertion blade 5.

[0058] As shown in Figures 3-5 , in order to facilitate the user to operate, a connecting plate 9 is installed at the upper end of the sleeve 1, the upper end of the connecting plate 9 is symmetrically fixed with a pull rod 10, the pull rod 10 is symmetrically arranged, which is beneficial to the suspension of the stems and leaves of the arbor seedlings, so as to realize the fixation of the arbor seedlings and avoid manual holding. The outer side of the upper end of the two pull rods 10 is provided with a handle 11, so as to facilitate the user to hold the handle 11 and step on the pedal 3, thereby being more beneficial to the user to exert force.

[0059] As shown in Figure 3 and Figure 4 , in order to reduce the entry of sand and gravel into the clamping assembly, a sandproof cloth belt 7 is fixed at the lower end of the outer side of the sleeve 1, the lower end of the sandproof cloth belt 7 is fixedly connected with the upper end of the outer side of the ground insertion blade 5, the sandproof cloth belt 7 has variable ability and does not affect the movement of the ground insertion blade 5. In addition, the existence of the sandproof cloth belt 7 can reduce the entry of sand and gravel into the clamping assembly, and improve the stability of the clamping assembly during work.

[0060] As shown in Figures 3-11 , in order to conveniently manually control the ground insertion blade 5, the sleeve 1 and the connecting lining plate 4 in the embodiment are fixedly connected, so that the distance between the sleeve 1 and the connecting lining plate 4 is invariable, and the sleeve 1 and the connecting plate 9 are movably connected, which is beneficial to the adjustment of the distance between the sleeve 1 and the connecting plate 9. The sleeve 1 is provided with a driving member for driving the transmission plate 15 to rotate, the driving member comprises a connecting sliding rod 14, the connecting sliding rod 14 is arranged in the sleeve 1, and the connecting sliding rod 14 is slidably connected with the sleeve 1 along the axial direction of the sleeve 1. The upper end of the connecting sliding rod 14 penetrates the sleeve 1 and is fixedly connected with the connecting plate 9, and a return spring 12 is installed between the outer side of the connecting sliding rod 14 and the connecting plate 9 and the sleeve 1, the return spring 12 is mainly used for resetting after driving the connecting plate 9 to move.

[0061] In addition, in order to make the connecting slide rod 14 move to drive the transmission plate 15 to move, the driving member further comprises a first connecting rod 19, 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, the other end of the second connecting rod 20 is hingedly connected with the connecting slide rod 14.

[0062] In the scheme, the manual control pull rod 10 moves to drive the connecting plate 9 to move, so as to adjust the distance between the connecting plate 9 and the sleeve 1, when the distance between the connecting plate 9 and the sleeve 1 is shortened, the connecting slide rod 14 goes down, the angle between the first connecting rod 19 and the second connecting rod 20 is reduced, the transmission plate 15 is further pressed, the lower end of the ground inserting blade 5 moves towards 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 into the sand, in addition, the ground inserting blade 5 drives the inner lining plate 6 to make the hollow hose 13 close to each other, then the hollow hose 13 presses the root of the arbor seedling, so as to fix the root of the arbor seedling, so that the sleeve 1 drives the root of the arbor seedling to insert into the sand, when the distance between the connecting plate 9 and the sleeve 1 is lengthened, the connecting slide rod 14 goes up, the angle between the first connecting rod 19 and the second connecting rod 20 is increased, the transmission plate 15 is driven to move, the lower end of the ground inserting blade 5 moves away from the axis of the sleeve 1, so that the ground inserting blade 5 is unfolded, and the arbor seedling root is released, so as to prevent the clamping assembly from taking out the seedling root system when it is separated from the sand.

[0063] As shown in Figure 4 In order to improve the stability of the connecting plate 9 when moving, a sleeve 8 is fixed on the lower end of the connecting plate 9, the sleeve 8 is slidably connected with the upper end of the outer side of the sleeve 1, through the sliding connection between the sleeve 8 and the sleeve 1, the stability of the connecting plate 9 when moving is improved.

[0064] During use (operation), firstly, insert the roots of the sapling into the sleeve 1 through the notch 2. Press down on the handle 11 to cause the lifting rod 10 to drive the connecting plate 9 downward. At this time, the return spring 12 is compressed, shortening the distance between the connecting plate 9 and the sleeve 1. The connecting slide rod 14 moves downward, making the angle between the first connecting rod 19 and the second connecting rod 20 smaller, further squeezing the transmission plate 15, causing the lower end of the insertion blade 5 to move towards the axis of the sleeve 1. This allows the insertion blade 5 to form a conical structure, facilitating better insertion into the sand. In addition, the insertion blade 5 drives the inner lining plate 6, causing the hollow hoses 13 to move closer together, which in turn squeezes the roots of the sapling, fixing the roots so that the sleeve 1 can drive the sapling roots into the sand. During this process, due to gravity, the limiting pressure block 16 is at the lower end of the connecting slide 18, and the transmission plate 15 causes the wedge groove 17 to squeeze and limit the pressure block. Block 16, thereby causing the limiting pressure block 16 to move to the upper end of the connecting slide 18, realizes the limiting function, and avoids excessive movement of the transmission plate 15. After the roots of the tree seedling are planted into the sand, the handle 11 is pulled upward, which increases the distance between the connecting plate 9 and the sleeve 1. The return spring 12 relaxes, and the connecting slide 14 moves upward, which increases the angle between the first connecting rod 19 and the second connecting rod 20, thereby driving the transmission plate 15 to move. This causes the lower end of the ground-inserting blade 5 to move away from the axis of the sleeve 1, thereby causing the ground-inserting blade 5 to unfold and release the roots of the tree seedling, so as to prevent the clamping component from pulling out the seedling roots when leaving the sand. During this process, the transmission plate 15 drives the wedge groove 17 to move away from the limiting pressure block 16. At this time, the limiting pressure block 16 moves downward to the lower end of the connecting slide 18 under the action of gravity. Throughout the process, the limiting pressure block 16 and the wedge groove 17 always abut against each other, thereby ensuring the stability of the transmission plate 15 during movement.

[0065] Example 2:

[0066] like Figures 12-14 As shown, the difference between this embodiment and embodiment one is that, in order to reduce the manual burden, the ground-inserting blade 5 can move automatically according to the situation of entering and exiting the sand. Specifically, the sleeve 1 is slidably connected to the connecting liner 4, and the sleeve 1 is fixedly connected to the connecting plate 9. The sleeve 1 is provided with a driving component for driving the transmission plate 15 to rotate. The driving component includes a first connecting rod 19, which is rotatably installed on one end of the transmission plate 15 near 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.

[0067] Sand-breaking cone 21 is fixed to the outside of the ground-inserting blade 5. Sand-breaking cone 21 has a tetrahedral structure and a cavity is opened on the upper surface of sand-breaking cone 21.

[0068] In the present scheme, when the sleeve 1 is inserted into the sand, the sleeve 1 moves downward, the sand resistance is applied to the insertion blade 5, so that the connecting lining plate 4 moves upward relative to the sleeve 1, so that the limiting pressing block 16 is separated from the wedge-shaped groove 17, the sand resistance extrudes the insertion blade 5, so that the insertion blade 5 moves towards the shaft of the sleeve 1, so that the insertion blade 5 gradually approaches to form a conical structure, which is convenient for inserting into the sand inside, when the sleeve 1 is pulled out of the sand, the sleeve 1 moves upward, and the connecting lining plate 4 slides downward in the sleeve 1 under the action of gravity and sand resistance, further driving the limiting pressing block 16 to move downward and press the wedge-shaped groove 17, so that the transmission plate 15 drives the insertion blade 5 to move away from the shaft of the sleeve 1, so as to realize the expansion of the clamping assembly, so as to separate the sleeve 1 from the tree root.

[0069] In order to improve the stability of the connection between the connecting lining plate 4 and the sleeve 1, the limiting sliding block 23 is fixed at equal intervals on the outer side of the connecting lining plate 4 close to the upper end position, and the limiting sliding groove 22 is arranged at the lower end of the sleeve 1 and is in sliding connection with the limiting sliding block 23, so as to improve the stability of the connecting lining plate 4 during movement.

[0070] In use, first, the roots of the tree seedlings are placed into the sleeve 1 from the gap groove 2, the roots of the tree seedlings are placed in the hollow hose 13, the insertion blade 5 is abutted with the sand surface, the handle 11 is pressed gently to make the lifting rod 10 push the sleeve 1 to move downward, so as to ensure that the sleeve 1 moves downward and the insertion blade 5 does not completely enter the inside of the sand, at this time, the end of the sleeve 1 approaches the upper end of the insertion blade 5, so that the included angle between the first connecting rod 19 and the second connecting rod 20 becomes smaller, further extruding the transmission plate 15, so that the lower end of the insertion blade 5 moves towards the shaft of the sleeve 1, so that the insertion blade 5 is combined to form a conical structure, which is convenient for inserting into the inside of the sand, in the process, the insertion blade 5 drives the inner lining plate 6 to make the hollow hose 13 close to each other, so as to realize the fixation of the roots of the tree seedlings, and then the handle 11 is pressed and the tread plate 3 is stepped down, so that the insertion blade 5 drives the sleeve 1 to insert into the inside of the sand.

[0071] After the roots of the tree seedlings are placed into the inside of the sand, the handle 11 is pulled upward, so that the sleeve 1 moves upward, initially, the insertion blade 5 is not expanded outwardly due to the extrusion of the sand, and in the process, the sleeve 1 moves upward, the connecting lining plate 4 slides to the lowermost end of the sleeve 1 under the action of the sand resistance and its own gravity, so that the distance between the sleeve 1 and the connecting lining plate 4 increases, further increasing the included 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 insertion blade 5 moves away from the shaft direction of the sleeve 1, so that the insertion blade 5 is expanded, the roots of the tree seedlings are released, so as to prevent the clamping assembly from taking out the roots of the seedlings when it is separated from the sand.

[0072] Example three:

[0073] As Figure 15 shown, the embodiment differs from embodiment one in that the first connecting rod 19 and the second connecting rod 20 are replaced by a flexible steel wire rope 25, which connects the lower end of the connecting slide rod 14 and the end of the transmission plate 15 away from the wedge-shaped slot 17.

[0074] In this scheme, the lower end of the connecting slide rod 14 needs to abut against the transmission plate 15 to drive the transmission plate 15 to move, so that the transmission plate 15 drives the ground insertion blade 5 to move towards the axial direction of the casing 1. When the ground insertion blade 5 moves away from the axial direction of the casing 1, the flexible steel wire rope 25 can be pulled to make the connecting slide rod 14 drive the flexible steel wire rope 25 to be tensioned, and then drive the transmission plate 15 to move.

[0075] Compared with embodiment one, in this scheme, the flexible steel wire rope 25 is connected between the connecting slide rod 14 and the transmission plate 15, so it is not necessary to consider that the sand entering the inside of the clamping assembly affects the shaft connection effect.
