Description

Technical Field

[0001] This invention relates to the field of alpine soil remediation technology, and in particular to a remediation device and method for degraded alpine meadows. Background Technology

[0002] Alpine meadows are a core ecological barrier in my country's cold regions, serving functions such as water conservation and soil and water retention. Affected by climate change, overgrazing, and rodent and insect pests, they have degraded on a large scale, resulting in problems such as decreased vegetation cover and soil desertification, threatening ecological security and the development of animal husbandry. The restoration of degraded meadows has become a key focus of ecological governance.

[0003] Reseeding with native grass species is the core method for restoring degraded meadows. Reseeding can be done by broadcasting, rowing, or drone seeding to quickly restore vegetation cover. The effectiveness is highly dependent on the compatibility of the equipment.

[0004] The following technical problems exist in the actual use of row sowing: First, the sowing depth control accuracy is low. The surface of alpine meadows is rugged and the humus layer is thin. Existing equipment rigidly opens furrows, resulting in large fluctuations in sowing depth (too deep in the raised areas and too shallow in the sunken areas), which affects the germination and survival of grass seeds. Second, there is a lack of coordination between furrow opening and seed protection. Existing straight-cut furrow openers are prone to damaging the fragile soil structure. After furrowing, the furrow walls quickly converge, causing grass seeds to aggregate. It is impossible to guarantee the time for grass seeds to disperse, resulting in poor sowing quality. Summary of the Invention

[0005] The purpose of this invention is to address the problem that existing equipment with rigid trenching results in large fluctuations in sowing depth, which affects the germination and survival of grass seeds. Therefore, this invention proposes a restoration device and method for degraded alpine meadows.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A restoration device for degraded alpine meadows includes a frame, with multiple strip seeding units mounted at the bottom of the frame. Each strip seeding unit includes a mounting base mounted on the frame. A front connecting seat is rotatably connected to the front of the mounting base, and a cutting wheel is rotatably connected to one end of the front connecting seat. A truss is installed inside the front connecting seat, and a trenching component is installed inside the truss. The trenching assembly includes a retaining rod with a mounting frame inserted inside. The soil cut by the cutting wheel is pushed into a narrow trench to accommodate the grass seeds during the seed falling by a trencher mounted on the bottom of the mounting frame. A wheel frame is mounted in the middle of the retaining rod, and the trencher is raised and lowered synchronously by a contour wheel mounted in the wheel frame to maintain a consistent trenching depth under uneven terrain. It also includes a seed storage unit mounted on the frame for storing and conveying grass seeds to the rear of the furrow opener.

[0007] As a further description of the above technical solution: The trenching assembly also includes a side guide rod fixed to the lower surface of the truss, and two middle guide rods are fixed in the middle of the upper surface of the retaining rod. Two springs are sleeved on the outer surface of both the side guide rod and the middle guide rod.

[0008] As a further description of the above technical solution: A lower electro-hydraulic rod is fixed to one side of the upper surface of the retaining rod, and one end of the lower electro-hydraulic rod is connected to the mounting bracket.

[0009] As a further description of the above technical solution: A positioning frame is mounted on the outer wall of the mounting frame. A soil-breaking rod is installed at one end of the positioning frame, and a soil-loosening component is fixed at the bottom end of the soil-breaking rod.

[0010] As a further description of the above technical solution: One end of the truss is equipped with a rear connecting seat, and one end of the rear connecting seat is rotatably connected to a press wheel. Two connecting rods are installed on the surfaces of multiple trusses, and both sides of the frame are equipped with an upper electric hydraulic rod, one end of which is connected to one of the connecting rods.

[0011] As a further description of the above technical solution: The seed storage unit includes a seed storage box fixed to the upper surface of the frame. Multiple seed distribution boxes are fixedly connected to the bottom of the seed storage box. Seeding wheels are rotatably connected inside the seed distribution boxes. The multiple seed distribution wheels are connected together by a connecting shaft. A stirring shaft is rotatably connected inside the seed storage box. A pulley is fixed to one end of both the stirring shaft and the connecting shaft. A synchronous belt is connected to the surfaces of two pulleys. A motor with its output end connected to one of the pulleys is installed on the side of the upper surface of the frame near the seed storage box.

[0012] As a further description of the above technical solution: The bottom of the seed box is fixedly connected to a seed discharge pipe. A seed protection frame is installed at the bottom of one side of the mounting frame. A seed lowering pipe is fixed inside the seed protection frame. The top of the seed lowering pipe passes through the truss and is sleeved on the outer surface of the seed discharge pipe.

[0013] A method for restoring degraded alpine meadows includes the following steps: S1. Preparation stage before repair: Equipment debugging and parameter adaptation 1. Equipment connection and inspection: Connect the frame to the tractor to ensure stable power transmission and proper coordination of all components; 2. Parameter preset: Adjust the wheel frame position to set the sowing depth, adjust the soil breaking rod height to set the loosening depth, and calibrate the seeding wheel speed to ensure accurate seeding rate; 3. Seed preparation: Pack the pretreated native grass seeds into the seed storage box and stir them to prevent clumping; S2, Core Sowing Operation Stage: Complete the following steps in an orderly manner: furrowing, sowing, seed protection, soil loosening, and compaction. 1. Equipment entry into the soil: The electric hydraulic lever is operated to lower the strip seeding unit, allowing the cutting wheel, furrow opener, etc. to cut into the soil, and the contour wheel and the compaction wheel to fit against the ground surface; 2. Cutting and widening the trench: The tractor pulls the frame to move, the cutting wheel cuts out the foundation gap, and the trencher widens it into a narrow trench; 3. Quantitative seed protection: The motor drives the seeding wheel to quantitatively distribute the grass seeds. The seeds fall to the bottom of the furrow through the seeding pipe and the seeding tube. The seed protection frame prevents the furrow walls from immediately closing and ensures that the grass seeds are dispersed. 4. Soil loosening and compaction: The soil loosening component loosens the soil simultaneously to reduce resistance to seedling emergence, and the tail compaction wheel lightly compacts and levels the ground surface; S3. Dynamic Adaptation Phase of Operation Process: Ensuring Consistent Seeding Depth Across the Entire Area 1. Passive contouring: The contouring wheel, in conjunction with a spring, drives the trencher to rise and fall with the terrain, initially ensuring consistent sowing depth; 2. Active fine-tuning: Activate the lower electric hydraulic rod to correct the trenching depth and avoid uneven depth; 3. Channel adaptation: The seeding tube moves synchronously with the mounting frame to ensure unobstructed seeding channel; S4, Post-Repair Support Phase Post-restoration support: Implement a grazing ban in the area for 1-2 years; use biological control to prevent rodent and insect pests; cover the area with straw / non-woven fabric to retain moisture and warmth, and improve seedling survival rate if necessary.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: By setting up strip seeding units, precise control of seeding depth is achieved to adapt to complex terrain. Through the cooperation of contour wheels, side guide rods, center guide rods and springs, passive contour adaptation to the terrain is achieved, driving the holding rod and furrow opener to rise and fall synchronously, ensuring consistent seeding depth under uneven terrain. The active fine-tuning function of the electric hydraulic rod is superimposed to further correct seeding depth deviation, completely solving the problem of seeding too deep in raised areas and too shallow in depressed areas, and improving the germination rate of grass seeds. The arc-shaped sliding trench opener, combined with the front-mounted cutting design of the cutting wheel, can gently expand soil gaps to form narrow trenches, reducing damage to the thin humus layer of alpine meadows; the seed protection frame wraps around the seed tube, which can delay the time for the narrow trench walls to close, ensuring that the grass seeds are evenly dispersed and avoiding aggregation and compression; the connecting plate at the end of the seed protection frame can also reduce the operating resistance of the soil-breaking rod and improve the smoothness of operation. At the same time, the soil-breaking rod and the trencher move coaxially and synchronously, and the soil-loosening component can precisely loosen the soil layer above the grass seed's landing position, which reduces the resistance of the grass seed breaking the soil and prevents the grass seed from shifting. The soil-loosening depth can be adjusted by the screw to adapt to the germination requirements of different grass seeds, eliminating the need for a separate soil-loosening process and improving work efficiency.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figure 1 - Figure 8 As shown, the present invention provides: A restoration device for degraded alpine meadows includes a frame 10. Specifically, the front end of the frame 10 is equipped with a connector, and the frame 10 is connected to a four-wheel tractor through the connector. The four-wheel tractor pushes the frame 10 to move. The bottom of the frame 10 is equipped with multiple strip seeding units 20. Each strip seeding unit 20 includes a mounting base 21 mounted on the frame 10. A front connecting base 22 is rotatably connected to the front of the mounting base 21, and a cutting wheel 23 is rotatably connected to one end of the front connecting base 22. A truss 24 is installed inside the front connecting base 22, and a trenching component 29 is installed inside the truss 24.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the trenching assembly 29 includes a retaining rod 291, into which a mounting bracket 292 is inserted. Specifically, the top of the mounting bracket 292 is inserted into the truss 24. In this state, the mounting bracket 292 can move vertically up and down within the retaining rod 291 and the truss 24. The soil cut by the cutting wheel 23 is pushed out into a narrow trench to accommodate the grass seeds during the falling of the seeds by the trench opener 293 mounted at the bottom of the mounting bracket 292. Preferably, the trench opener 293 is an arc-shaped sliding cutter. A wheel frame 297 is mounted in the middle of the retaining rod 291. The trench opener 293 is synchronously raised and lowered by the contour wheel 298 mounted in the wheel frame 297 to maintain a consistent trenching depth under uneven terrain. Preferably, a counterweight (not shown in the figure) is provided at the end of the retaining rod 291 away from the trench opener 293 to ensure the stability of the retaining rod 291 and to ensure that the contour wheel 298 can drive the retaining rod 291 to move horizontally up and down together when it moves up and down. The trenching assembly 29 also includes a side guide rod 294 fixed to the lower surface of the truss 24. Specifically, the bottom end of the side guide rod 294 passes through the retaining rod 291 and extends below the retaining rod 291. Two middle guide rods 295 are fixed to the middle of the upper surface of the retaining rod 291. Specifically, the top end of the middle guide rod 295 passes through the truss 24 and extends above the truss 24. Two springs 296 are fitted on the outer surfaces of both the side guide rod 294 and the middle guide rod 295. Specifically, of the two springs 296 on the side guide rod 294, the two ends of the upper spring 296 are respectively connected to the top end of the side guide rod 294. The upper surface of the retaining rod 291 is connected to the lower surface of the retaining rod 291 and the bottom end of the side guide rod 294, respectively. Preferably, in order to increase the contact area between the spring 296 and the truss 24, two contact plates are fixed in the middle of the upper surface of the truss 24. Among the two springs 296 on the middle guide rod 295, the two ends of the upper spring 296 are connected to the top end of the middle guide rod 295 and the upper surface of the contact plate, respectively, while the two ends of the lower spring 296 are connected to the lower surface of the retaining rod 291 and the bottom end of the middle guide rod 295, respectively. Specifically, with the cooperation of two side guide rods 294, two middle guide rods 295, and spring 296, the retaining rod 291 can be suspended on the lower surface of the truss 24 and remain stable. Meanwhile, the wheel frame 297 is located in the middle area of ​​the retaining rod 291 and is installed by bolts for easy disassembly. Before use, the position of the wheel frame 297 can be raised or lowered after removing the bolts, so that the distance between the bottom of the contour wheel 298 and the bottom of the furrow opener 293 can be adjusted according to the sowing depth. After adjustment, it can be re-fixed with bolts. As the furrow opener 293 moves along the soil gap cut by the cutting wheel 23, it expands the gap, making it into a narrow groove. In this state, it can facilitate the falling of grass seeds and ensure that the narrow groove can close after the furrow opener 293 moves away. Meanwhile, during the movement, since the contour wheel 298 is above the furrow opener 293 and is in contact with the soil surface, when encountering uneven terrain, the contour wheel 298 will move up and down under the action of the terrain and the spring 296 to adapt to the uneven terrain. During the up and down movement, the retaining rod 291 will also move up and down, thereby driving the furrow opener 293 to move up and down, so that the furrowing depth is consistent in different terrain positions under uneven terrain, avoiding the situation that grass seeds are sown too deep in convex terrain and too shallow in depression terrain.

[0020] like Figure 1 and Figure 3 As shown, a lower electro-hydraulic rod 299 is fixed to one side of the upper surface of the retaining rod 291. One end of the lower electro-hydraulic rod 299 is connected to the mounting frame 292. Specifically, during the contouring process of the contouring wheel 298, in order to ensure that the trenching depth of the trencher 293 is as consistent as possible, by activating the lower electro-hydraulic rod 299, the mounting frame 292 can drive the trencher 293 to further actively adjust up and down to ensure that the trenching depth is consistent and further avoid the occurrence of uneven sowing depth under uneven terrain.

[0021] like Figure 3 and Figure 4 As shown, a positioning frame is mounted on the outer wall of the mounting frame 292. A soil-breaking rod is installed at one end of the positioning frame, and a soil-loosening component 2910 is fixed at the bottom end of the soil-breaking rod. In particular, the soil-breaking rod is installed and fixed to the positioning frame by means of studs. At the same time, it can be adjusted up and down according to the needs of use to change the depth of the soil-loosening component 2910 after entering the soil. This ensures that the soil-loosening component 2910 remains in the soil layer above the grass seed drop position as it moves with the furrow opener 293 after entering the soil, thereby ensuring that the soil-loosening component 2910 will not cause the grass seed to shift after falling. Specifically, the soil-breaking rod and the furrow opener 293 are on the same straight line. As the furrow opener 293 moves, the soil-breaking rod moves along with it. During this process, the soil-loosening component 2910 moves within the soil layer above the grass seed's landing position, which loosens the soil layer above the grass seed to a certain extent, making it easier for the grass seed to germinate and emerge.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, one end of the truss 24 is equipped with a rear connecting seat 25, and one end of the rear connecting seat 25 is rotatably connected to a press wheel 26. Two connecting rods 27 are installed on the surface of multiple trusses 24. Both sides of the frame 10 are equipped with an upper electric hydraulic rod 28, one end of which is connected to one of the connecting rods 27. Specifically, after the equipment moves to the area to be repaired under the action of the tractor, the upper electric hydraulic rod 28 can drive the connecting rod 27 to drive multiple sets of strip seeding units 20 to move downward, so that the cutting wheel 23, furrow opener 293 and loosening component 2910 enter the soil. At this time, the press wheel 26 and the contour wheel 298 are on the soil surface. Then the equipment moves with the tractor and grass seeding can be carried out. During the process, the press wheel 26 located at the rear will press the soil above the seeding area to a certain extent. This pressing pressure will not drive the soil to be compacted. It is only to press and distribute a small amount of soil clods squeezed to the top during the narrow furrow opening process, so as to keep the soil surface as flat as possible.

[0023] like Figure 1 , Figure 5 , Figure 6 and Figure 8 As shown, the frame 10 is equipped with a seed storage unit 30 for storing and conveying grass seeds to the rear of the furrow opener 293. The seed storage unit 30 includes a seed storage box 31 fixed to the upper surface of the frame 10. Multiple seed distribution boxes are fixedly connected to the bottom of the seed storage box 31. Seeding wheels 32 are rotatably connected inside the seed distribution boxes. In particular, the surface of the seed distribution wheels 32 has multiple receiving slots for receiving grass seeds. When the receiving slots containing grass seeds rotate downwards with the seed distribution wheels 32, the grass seeds will fall down by gravity. The multiple seed distribution wheels 32 are connected together by a connecting shaft. A stirring shaft 33 is rotatably connected inside the seed storage box 31. One end of the stirring shaft 33 and the connecting shaft are fixed with pulleys, and the surfaces of the two pulleys are meshed with a synchronous belt. A motor 34 with its output end connected to one of the pulleys is installed on the upper surface of the frame 10 near the seed storage box 31. Specifically, the stirring shaft 33 inside the seed storage box 31 is linked with the seed dividing wheel 32 through the synchronous belt, which can stir the grass seeds in real time to prevent clumping and blockage. The motor 34 can control the speed of the seed dividing wheel 32, thereby controlling the falling interval of the grass seeds and thus controlling the sowing density. The bottom of the seed box is fixedly connected to a seed dispensing tube 35. Specifically, a positioning clamp is fixedly fitted on the outer surface of the seed dispensing tube 35, and one end of the positioning clamp is fixed to the connecting rod 27. A seed protection frame 36 is installed at the bottom of one side of the mounting frame 292. A seed lowering tube 37 is fixed inside the seed protection frame 36. The top end of the seed lowering tube 37 passes through the truss 24 and is fitted onto the outer surface of the seed dispensing tube 35. That is, the bottom end of the seed dispensing tube 35 is inserted into the seed lowering tube 37. At the same time, in this state, the seed lowering tube 37 can follow the installation. The frame 292 moves up and down together, maintaining its connection with the seed discharge tube 35 during the process. At the same time, the seed protection frame 36 wraps around the seed discharge tube 37 in a wrapping shape, so that after the furrow opener 293 opens a narrow furrow and the grass seeds fall into the bottom of the furrow through the seed discharge tube 37, the two sides of the furrow will not immediately come together. Instead, they will come together only after the seed protection frame 36 moves away from the position where the grass seeds fall. This prevents the two sides of the narrow furrow from coming together immediately after the grass seeds fall in, allowing the fallen grass seeds time to disperse and preventing them from being squeezed together by the close-up narrow furrow walls. Specifically, during the process of cutting and widening the slit to a narrow trench, the connecting shaft is driven to rotate by the motor 34, which in turn rotates the seeding wheel 32. During this process, grass seeds are quantitatively fed from the seed storage box 31 into the seed discharge pipe 35 and fall to the bottom of the trench via the seed discharge pipe 37. At the same time, during the sowing process, the soil loosening component 2910, which follows the seed protection frame 36, will loosen the soil layer above the grass seed drop position to reduce the pressure on the grass seeds to break through the soil. Preferably, the seed protection frame 36 has a connecting plate at its tail end, and one end of the connecting plate is in contact with the soil breaking rod. The connecting plate is used to ensure that the trench wall will not completely close before the loosening component 2910 passes over the grass seeds. It can reduce the soil breaking resistance of the soil breaking rod, so that it can move smoothly in the slightly closed narrow trench.

[0024] Specifically, this equipment for restoring degraded alpine meadows operates / is used as follows: 1. Equipment assembly and connection: Connect the frame 10 to the four-wheel tractor through the front connector, and check the reliability of the connection of the mounting base 21, front connecting base 22, truss 24 and other components of each row seeding unit 20; ensure that the seed discharge pipe 35 and the seed release pipe 37 of the seed storage unit 30 are properly connected, and that the press wheel 26 and the contour wheel 298 rotate flexibly. 2. Parameter preset adjustment: Seeding depth adjustment: Remove the fixing bolts of wheel frame 297, raise and lower the position of wheel frame 297 so that the distance between the bottom of the contour wheel 298 and the bottom of the trencher 293 matches the target seeding depth, and tighten the bolts to lock them after adjustment.

[0025] Soil loosening depth adjustment: Adjust the height of the soil breaking rod on the positioning frame by adjusting the screw to ensure that the soil loosening component 2910 is located in the soil layer above the grass seed drop position after entering the soil; Seeding rate calibration: Based on the grass seed type, preset the motor speed of 34, determine the seeding rate per unit length through the receiving groove specification of the seeding wheel 32, start the motor 34 for trial operation, and ensure uniform seeding; 3.

Task Initiation and Implementation: The electric hydraulic rod 28 is controlled to drive the connecting rod 27 to move multiple strip seeding units 20 downward as a whole, so that the cutting wheel 23, furrow opener 293, and loosening component 2910 cut into the soil, and the contour wheel 298 and the compaction wheel 26 are in contact with the ground surface. The tractor is started to move the frame 10. The cutting wheel 23 cuts the slits in front, and the ditch opener 293 expands along the slits to form a narrow ditch. The motor 34 drives the seeding wheel 32 to rotate, and the grass seeds fall into the bottom of the ditch through the seeding pipe 35 and the seeding pipe 37. The seed protection frame 36 slows down the ditch wall to ensure the grass seeds are dispersed. During operation, the contour wheel 298 moves the retaining rod 291 and the furrow opener 293 up and down with the terrain undulations, and the spring 296 buffers the impact; the lower electric hydraulic rod 299 is activated to actively and finely adjust the height of the furrow opener 293 according to the terrain changes to ensure consistent sowing depth; the loosening component 2910 loosens the soil simultaneously, and the compaction wheel 26 lightly compacts and levels the ground surface. 5. Finishing the work: After sowing, turn off the motor 34, operate the upper electric hydraulic rod 28 to lift the row sowing unit 20, so that each working part is removed from the soil; clean the seed storage box 31 and the seed discharge channel of residual grass seeds, and check the wear of equipment parts.

Cutting and widening the gap: The tractor pulls the frame 10 to move, the cutting wheel 23 cuts out the foundation gap, and the trencher 293 widens it into a narrow trench; 3. Quantitative seed protection: The starting motor 34 drives the seeding wheel 32 to quantitatively distribute the grass seeds. The grass seeds fall to the bottom of the ditch through the seeding pipe 35 and the seeding pipe 37. The seed protection frame 36 prevents the ditch wall from immediately closing and ensures that the grass seeds are dispersed. 4.

Multiple seed distribution boxes are fixedly connected to the bottom of the seed storage box (31). Seed distribution wheels (32) are rotatably connected inside the seed distribution boxes. Multiple seed distribution wheels (32) are connected together by a connecting shaft. A stirring shaft (33) is rotatably connected inside the seed storage box (31). A pulley is fixed to one end of both the stirring shaft (33) and the connecting shaft. A synchronous belt is meshed on the surfaces of the two pulleys. A motor (34) with its output end connected to one of the pulleys is installed on the side of the upper surface of the frame (10) near the seed storage box (31).

6. The restoration equipment for degraded alpine meadows according to claim 5, characterized in that, The bottom of the seed box is fixedly connected to a seeding tube (35), and the top of the seeding tube (37) passes through the truss (24) and is sleeved on the outer surface of the seeding tube (35).

7. A restoration method for a restoration device for degraded alpine meadows according to any one of claims 1-6, characterized in that, Includes the following steps: S1. Preparation stage before repair: Equipment debugging and parameter adaptation 1) Equipment connection and inspection: Connect the frame (10) to the tractor to ensure stable power transmission and coordinated operation of all components; 2). Parameter preset: Adjust the position of the wheel frame (297) to set the sowing depth, adjust the height of the soil breaking rod to set the loosening depth, and calibrate the rotation speed of the seeding wheel (32) to ensure accurate seeding. 3) Grass seed preparation: Put the pretreated native grass seeds into the seed storage box (31) and stir them to prevent clumping; S2, Core Sowing Operation Stage: Complete the following steps in an orderly manner: furrowing, sowing, seed protection, soil loosening, and compaction. 1) Equipment entry into the soil: Operate the upper electric hydraulic rod (28) to move the strip seeding unit (20) down, so that the cutting wheel (23), furrow opener (293), etc. can cut into the soil, and the contour wheel (298) and the compaction wheel (26) can fit against the ground surface; 2). Cutting and widening the gap: The tractor pulls the frame (10) to move, the cutting wheel (23) cuts out the gap in the foundation, and the trencher (293) widens it into a narrow trench; 3) Quantitative seed protection: Start the motor (34) to drive the seeding wheel (32) to quantitatively distribute the seeds. The grass seeds fall to the bottom of the ditch through the seeding pipe (35) and the seeding pipe (37). The seed protection frame (36) prevents the ditch wall from immediately closing and ensures that the grass seeds are dispersed. 4). Soil loosening and compaction: The soil loosening component (2910) loosens the soil simultaneously to reduce seedling emergence resistance, and the tail compaction wheel (26) lightly compacts and levels the ground surface; S3. Dynamic Adaptation Phase of Operation Process: Ensuring Consistent Seeding Depth Across the Entire Area 1) Passive contouring: The contouring wheel (298) and the spring (296) drive the trencher (293) to rise and fall with the terrain, initially ensuring consistent sowing depth; 2) Active fine-tuning: Activate the lower electric hydraulic rod (299) to correct the trenching depth and avoid uneven depth; 3) Channel adaptation: The seeding tube (37) moves synchronously with the mounting frame (292) to ensure unobstructed seeding channel; S4, Post-Repair Support Phase Post-restoration support: Implement a grazing ban in the area for 1-2 years; use biological control to prevent rodent and insect pests; cover the area with straw / non-woven fabric to retain moisture and warmth, and improve seedling survival rate if necessary.
