Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, specifically to a device and method for targeted carbon supplementation of manure in the tillage layer. Background Technology

[0002] In modern agricultural soil improvement practices, returning livestock and poultry manure to the field in synergy with organic carbon sources such as straw is an important way to improve soil organic matter and achieve agricultural carbon neutrality. However, existing methods have significant technical bottlenecks that restrict the full realization of their effects.

[0003] First, traditional trenching and fertilizing equipment is prone to soil adhesion and rapid accumulation during operation, leading to increased trenching resistance, poor trench shape quality, and even blockages. This forces frequent shutdowns for cleaning, severely impacting operational efficiency and continuity. Second, current technologies often focus on mixing manure and carbon before application. This mixture has high viscosity and poor flowability, easily clogging delivery pipelines and the fertilizer trenching device, resulting in low practicality. Applying manure and carbon separately and sequentially fails to create a localized, ideal high carbon-to-nitrogen ratio microenvironment, hindering the efficient synergistic work of microorganisms and significantly reducing nutrient retention and soil improvement effects.

[0004] Therefore, it is necessary to provide a device and method for targeted carbon supplementation of manure in the topsoil layer to solve the problems mentioned in the background art. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a top-layer manure-directed carbon supplementation device, comprising: a mounting base with a T-shaped mounting groove on its top and a hydraulic cylinder fixedly mounted on its bottom; a fixing plate fixedly mounted on the extended end of the hydraulic cylinder, with two columns symmetrically fixedly mounted on the bottom of the fixing plate and an extension plate fixedly mounted on the side of the fixing plate; two symmetrically arranged guide rails, each fixedly mounted on one of the two columns, with guide grooves on the guide rails; a trenching mechanism rotatably mounted between the two columns; and a soil cleaning assembly. The device includes a sliding plate, a bulldozer plate, and a vibration mechanism. Two support shafts are fixedly installed on both sides of the sliding plate, and sliders are rotatably mounted on the support shafts. The two sliders slide along guide grooves on two guide rails. The bulldozer plate is V-shaped, and two T-shaped sliding rods are fixedly installed on its back side. Two sliding holes are opened on the sliding plate, and the two sliding rods slide through the two sliding holes respectively. A first spring is sleeved on the sliding rod, and the two ends of the first spring abut against the bulldozer plate and the sliding plate respectively. A vibration mechanism is fixedly installed on the bulldozer plate.

[0006] Preferably, the guide groove is an annular groove composed of four arc-shaped guide rails. The four arc-shaped guide rails are a first guide rail located at the bottom of the guide rail disk, a second guide rail located at the top of the guide rail disk, and two third guide rails located on both sides of the guide rail disk for connecting the first guide rail and the second guide rail.

[0007] Preferably, the vibration mechanism includes: a support column, which is fixedly installed on the bulldozer plate and has a sliding cavity inside; a push rod, which is fixedly installed on the sliding plate, and a plurality of push plates are fixedly arranged at intervals on the push rod, and the push rod and push plates can slide along the sliding cavity; wherein, two back plates are symmetrically fixedly arranged on the side of the support column near the sliding plate, and two deflection grooves are symmetrically opened on the side of the support column near the back plates, and an L-shaped deflection plate is rotatably arranged in the deflection groove, one end of the deflection plate extends into the sliding cavity and the other end extends into the bulldozer plate, and a striking block is fixedly arranged at the end of the deflection plate on the bulldozer plate, and a second spring is arranged between the deflection plate and the back plate.

[0008] Preferably, the trenching mechanism includes a turntable, guide plates, and breaking blocks. The turntable is rotatably installed between the two columns. Multiple arc-shaped guide plates are uniformly fixed on the turntable along the circumference, and the cross-sectional shape of the guide plates is V-shaped. A V-shaped breaking block is fixed at the end of the guide plate.

[0009] Preferably, the bottom sides of the sliding plate and the bulldozer plate are V-shaped with the same cross-sectional shape as the guide plate. Two L-shaped locking blocks are symmetrically fixed on both sides of the bottom of the sliding plate. A C-shaped locking groove is formed between the L-shaped locking blocks and the sliding plate. The guide plate slides along the locking groove. Two rotating rollers are rotatably mounted on the L-shaped locking blocks. The two rotating rollers can roll along the back side of the guide plate.

[0010] Preferably, each of the two columns is slidably provided with a sliding column, a first hydraulic telescopic rod is provided between the sliding column and the fixed plate, and a depth-limiting wheel is rotatably provided at the end of the sliding column.

[0011] Preferably, each of the two sliding columns is fixedly provided with an L-shaped support plate, the two L-shaped support plates are arranged in parallel, and the bottom of the two support plates are symmetrically inclined with soil covering plates, and the two soil covering plates are arranged in a V-shape; at least two directional rods are fixedly provided vertically downward at the end of the extension plate, and the directional rods are slidably connected to the L-shaped support plates.

[0012] Preferably, the extension plate has two mounting holes, and two material feeding pipes are fixedly installed in the two mounting holes respectively. The bottom of the two material feeding pipes is fitted with a first sleeve and a second sleeve in sequence along the extension direction of the extension plate. Multiple second hydraulic telescopic rods are provided between the first sleeve and the second sleeve and the extension plate respectively, and a V-shaped soil retaining plate is fixedly installed on the first sleeve.

[0013] A method for targeted carbon supplementation with manure in the topsoil includes the following steps;

[0014] S1. Install the mounting base on the traction mechanism, and at the same time drive the hydraulic cylinder to adjust the working height of the entire device according to the fertilization requirements. Adjust the height of the depth limiting wheel and the soil covering plate through the first hydraulic telescopic rod, and set the trenching depth and soil covering effect.

[0015] S2. The traction mechanism pulls the device forward as a whole, while driving the trenching mechanism to rotate to excavate the trench. At the same time, the rotation of the trenching mechanism can drive the soil cleaning component to slide along the guide groove, so that the soil cleaning component slides back and forth along the guide plate to clean the soil clods on the guide plate.

[0016] S3. When the soil clearing component slides to the end of the guide plate and contacts the soil breaking block, the sliding plate continues to slide, causing the push rod and push plate to slide into the sliding cavity and push the deflection plate to deflect. When the push plate disengages from the deflection plate, the second spring drives the deflection plate to strike the bulldozer plate, causing the bulldozer plate to vibrate and transmit the vibration to the soil breaking block and the guide plate.

[0017] S4. By arranging the first and second sleeves in front and behind, two feeding pipes with adjustable height are installed. Manure is applied to the bottom of the ditch through the feeding pipe connected to the first sleeve, while carbon is applied above the manure layer through the other feeding pipe, so that a layered structure of manure at the bottom and carbon at the top is formed in the ditch.

[0018] S5. Using the two V-shaped soil covering plates, the excavated soil is refilled into the ditch, and covered with manure and carbon materials to complete the targeted carbon supplementation operation.

[0019] Compared with the prior art, the present invention provides a device and method for targeted carbon supplementation of manure in the topsoil, which has the following beneficial effects:

[0020] This invention, through the linkage between the designed guide rail disc and the soil-cleaning component, transforms the rotational force of the trenching mechanism into the reciprocating motion of the soil-cleaning component. This enables automatic and synchronous cleaning of the guide plate and soil clods while trenching. Furthermore, the mechanical vibration mechanism generates high-frequency impacts when the soil-cleaning component reaches key positions, directly transmitting vibrational force to firmly adhered soil clods, loosening them. This allows for simultaneous trenching and cleaning, ensuring the trenching mechanism maintains optimal operating conditions. The invention also utilizes independently arranged and height-adjustable first and second sleeves to precisely apply liquid or solid manure to the bottom of the ditch while simultaneously spreading dry carbon on top of the manure layer. This directional, layered application technology creates an ideal microenvironment in the soil where manure and carbon are closely adjacent, significantly promoting microbial activity, effectively reducing nitrogen volatilization and leaching, improving nutrient utilization, and significantly enhancing the soil's carbon sequestration capacity.

[0028] Please see Figures 1-6 In this embodiment of the invention, a topsoil manure-directed carbon supplementation device includes: a mounting base 1 with a T-shaped mounting groove on its top and a hydraulic cylinder 11 fixedly mounted on its bottom; a fixing plate 2 fixedly mounted on the extended end of the hydraulic cylinder 11, with two uprights symmetrically fixedly mounted on the bottom of the fixing plate 2 and an extension plate 22 fixedly mounted on the side of the fixing plate 2; two symmetrically arranged guide rails 3 fixedly mounted on the two uprights 21 respectively, with guide grooves 31 on the guide rails 3; a trenching mechanism 4 rotatably mounted between the two uprights 21; and a soil cleaning assembly 5 including a sliding plate 51, a bulldozing plate 52, and a vibration mechanism 5. 3. Two support shafts 511 are fixedly installed on both sides of the sliding plate 51. A slider 512 is rotatably installed on the support shaft 511. The two sliders 512 are slidably installed along the guide grooves 31 on the two guide rails 3 respectively. The bulldozer plate 52 is V-shaped, and two T-shaped sliding rods 521 are fixedly installed on its back side. Two sliding holes are opened on the sliding plate 51. The two sliding rods 521 slide through the two sliding holes respectively. A first spring 522 is sleeved on the sliding rod 521. The two ends of the first spring 522 abut against the bulldozer plate 52 and the sliding plate 51 respectively. A vibration mechanism 53 is fixedly installed on the bulldozer plate 52.

[0029] In this embodiment, the guide groove 31 is an annular groove composed of four arc-shaped guide rails. The four arc-shaped guide rails are a first guide rail 311 located at the bottom of the guide rail disk 3, a second guide rail 312 located at the top of the guide rail disk 3, and two third guide rails 313 located on both sides of the guide rail disk 3 for connecting the first guide rail 311 and the second guide rail 312.

[0030] In addition, the inner side of the guide channel 31 is provided with multiple soil discharge ports 314, and the two side walls of the guide channel 31 are set to be arc-shaped. This makes it possible that when some soil clods enter the guide channel 31, they will not stay too much inside the guide channel 31. Furthermore, the slider 512 and the guide channel 31 can be set to a clearance fit, that is, the slider 512 is not completely in contact with the side wall of the guide channel 31. When sliding, it is in contact with one side wall of the guide channel 31 and rolls to slide. This makes it possible that when there are soil clods inside the guide channel 31, the sliding of the slider 512 will not be affected, and the sliding of the slider 512 can also squeeze the soil clods out from the soil discharge ports 314 or the front side of the guide channel 31, thereby ensuring that the slider 512 can slide effectively along the guide channel 31.

[0031] In this embodiment, the vibration mechanism 53 includes: a support column 531, which is fixedly installed on the bulldozer plate 52 and has a sliding cavity inside; a push rod 532, which is fixedly installed on the sliding plate 51, and a plurality of push plates 533 are fixedly arranged at intervals on the push rod 532. The push rod 532 and the push plates 533 can slide along the sliding cavity; wherein, two back plates 534 are symmetrically fixedly arranged on the side of the support column 531 near the sliding plate 51, and two deflection grooves are symmetrically opened on the side of the support column 531 near the back plates 534. An L-shaped deflection plate 535 is rotatably arranged in the deflection groove. One end of the deflection plate 535 extends into the sliding cavity, and the other end extends into the bulldozer plate 52. A striking block 536 is fixedly arranged at one end of the deflection plate 535 on the bulldozer plate 52. A second spring 537 is arranged between the deflection plate 535 and the back plate 534.

[0032] It should be noted that there is a gap between the striking block 536 and the bulldozing plate 52, meaning that the deflecting plate 535 can deflect in both directions. A ramp (not shown in the figure) can be provided on the portion of the deflecting plate 535 extending into the sliding cavity, facing the bulldozing plate 52. When the push plate 533 slides inward along the sliding cavity, it pushes the deflecting plate 535 to deflect until it completely disengages from the deflecting plate 535, at which point the deflecting plate 535 returns to its original deflected position. When the push plate 533 slides out of the sliding cavity and returns to its original position, it slides along the ramp while pushing the deflecting plate 535 to deflect, allowing the push plate 533 to slide through without the deflecting plate 535 deflecting too much. Therefore, a gap can be provided between the striking block 536 and the bulldozing plate 52 to allow the deflecting plate 535 to deflect, ensuring that the push plate 533 can slide back to its original position.

[0033] In this embodiment, the trenching mechanism 4 includes a turntable 41, a guide plate 42, and a soil breaking block 43. The turntable 41 is rotatably installed between the two columns 21. Multiple arc-shaped guide plates 42 are uniformly fixed on the turntable 41 along the circumference, and the cross-sectional shape of the guide plate 42 is V-shaped. A V-shaped soil breaking block 43 is fixed at the end of the guide plate 42.

[0034] In implementation, such as Figure 1As shown, when the trenching work is carried out, the turntable 41 rotates clockwise, that is, in the opposite direction to the traction direction of the traction mechanism. The soil breaking block 43 and the soil guide plate 42 perform trenching work from bottom to top, and the soil block produced by trenching can be transported to the ground by the soil guide plate 42 and transported to both sides of the trench. At the same time, the soil breaking and soil transporting work are always carried out on the side of the trenching mechanism 4 located in the forward direction of the traction mechanism, which can prevent the excavated soil block from falling into the trench. At the same time, the soil cleaning component 5 works in conjunction to ensure that the soil breaking block 43 and the soil guide plate 42 do not have large soil blocks stuck to them when they are rotated back into the trench after completing the trenching work, further ensuring that the excavated trench can remain unobstructed, providing convenience for subsequent fertilization and carbonization work.

[0035] In addition, the power source for the rotation of the turntable 41 along the column 21 and the external drive mechanism can be a first toothed disc on the drive shaft of the turntable 41, a drive shaft 7 rotatably mounted on the fixed plate 2, and a second toothed disc mounted on the drive shaft 7. The first toothed disc and the second toothed disc are connected by a chain. At the same time, a chain drive channel is set inside the column 21 to ensure that dust does not enter the transmission system. Furthermore, a locking pin hole can be set in the drive shaft 7, so that the drive shafts 7 in two adjacent devices can be connected by a single pin. Thus, all the trenching mechanisms 4 can be driven by a single power drive mechanism.

[0036] In this embodiment, the bottom sides of the sliding plate 51 and the bulldozing plate 52 are V-shaped with the same cross-sectional shape as the guide plate 42. Two L-shaped locking blocks 513 are symmetrically fixed on both sides of the bottom of the sliding plate 51. A C-shaped locking groove is formed between the L-shaped locking blocks 513 and the sliding plate 51. The guide plate 42 is slidably disposed along the locking groove. Two rotating rollers 514 are rotatably disposed on the L-shaped locking blocks 513. The two rotating rollers 514 can roll along the back side of the guide plate 42.

[0037] It should be noted that the slot is also in a clearance sliding fit with the guide plate 42, that is, there is a gap between the sliding plate 51 and the guide plate 42, which allows a small amount of soil to pass through. The function of the L-shaped block 513 is to restrict the position of the sliding plate 51 on the guide plate 42, ensuring that the sliding plate 51 can push the bulldozer plate 52 to slide along the guide plate 42, and that the sliding process is less affected by soil and will not cause jamming.

[0038] It should be explained that the purpose of the bulldozer 52 is not to completely clean the soil clods on the guide plate 42, that is, it does not slide against the surface of the guide plate 42. It only cleans away most of the soil clods on the guide plate 42 to ensure that the guide plate 42 maintains a good soil conveying effect as much as possible. Similarly, the cleaning of the soil clods 43 is similar to the cleaning effect of the guide plate 42. It does not clean the soil clods completely, but prevents the accumulation of soil clods from preventing the soil clods 43 and the guide plate 42 from being unable to carry out trenching work.

[0039] In this embodiment, sliding columns 23 are slidably provided on both columns 21, and a first hydraulic telescopic rod is provided between the sliding column 23 and the fixed plate 2. A depth-limiting wheel 24 is rotatably provided at the end of the sliding column 23.

[0040] In this embodiment, L-shaped support plates 25 are fixedly installed on both sliding columns 23. The two L-shaped support plates 25 are arranged in parallel, and soil covering plates 26 are symmetrically and inclinedly installed at their bottoms. The two soil covering plates 26 are arranged in a V-shape. At least two directional rods 27 are fixedly installed vertically downward at the end of the extension plate 22. The directional rods 27 are slidably connected to the L-shaped support plates 25.

[0041] In this embodiment, the extension plate 22 has two mounting holes, and two material feeding pipes 6 are fixedly installed in the two mounting holes respectively. The bottom of the two material feeding pipes 6 is sequentially fitted with a first sleeve 61 and a second sleeve 62 along the extension direction of the extension plate 22. Multiple second hydraulic telescopic rods are respectively provided between the first sleeve 61 and the second sleeve 62 and the extension plate 22, and a V-shaped retaining plate 63 is fixedly installed on the first sleeve 61.

[0042] Specifically, installing a V-shaped retaining plate 63 on the first fertilization pipe 61 can further prevent soil clods in the ditch from adhering to the first pipe 61, thus ensuring that the first pipe 61 will not be blocked. At the same time, the retaining plate 63 can, to a certain extent, separate the excavated ditch and prevent manure from flowing to the front of the first pipe 61 during application. This allows for strict control of the manure application height, i.e., the amount of manure applied, ensuring that the manure layer and carbon layer at the same height maintain a good ratio, resulting in better carbon supplementation.

[0043] A method for targeted carbon supplementation with manure in the topsoil includes the following steps;

[0044] S1. Install the mounting base 1 on the traction mechanism, and at the same time drive the hydraulic cylinder 11 to adjust the working height of the entire device according to the fertilization requirements. Adjust the height of the depth limiting wheel 24 and the soil covering plate 26 through the first hydraulic telescopic rod, and set the trenching depth and soil covering effect.

[0045] Specifically, the entire device can be regarded as a whole module. The appropriate number of this module can be selected according to the specific fertilization needs and installed at intervals on the traction mechanism. The traction mechanism can be a tractor or other power traction equipment. For the installation of the mounting seat 1, a crossbeam structure can be set on the traction mechanism. The mounting seat 1 is slidably installed on the crossbeam by opening the mounting groove on the mounting seat 1. After installation, the spacing between each device can be adjusted. At the same time, the mounting seat 1 is locked on the crossbeam by using a locking pin or hydraulic cylinder 11.

[0046] S2. The traction mechanism is used to pull the device forward as a whole, while driving the trenching mechanism 4 to rotate to excavate the trench. At the same time, the rotation of the trenching mechanism 4 can drive the soil cleaning component 5 to slide along the guide groove 31, so that the soil cleaning component 5 slides back and forth along the guide plate 42 to clean the soil clods on the guide plate 42.

[0047] Specifically, as the trenching mechanism 4 rotates, the soil-cleaning component 5 causes the sliders 512 on both sides of the sliding plate 51 to slide along the guide groove 31, that is, along the first guide rail 311, the second guide rail 312, and the third guide rail 313. When the slider 512 slides along the first guide rail 311, the soil-cleaning component 5 is located at the root of the guide plate 42, and the relative position between the soil-cleaning component 5 and the guide plate 42 remains unchanged. When the slider 512 slides from the first guide rail 311 into the third guide rail 313, the soil-cleaning component 5 slides along the guide plate 42, thereby pushing the bulldozer plate 52 to slide and clean the soil clods on the guide plate 42. Before the slider 512 slides from the third guide rail 313 into the second guide rail 312, the sliding plate 51 drives the bulldozer plate 52 to slide and press against the broken soil block 43. Furthermore, as the slider 512 slides along the third guide rail 313, the sliding plate... 51 will continue to slide, causing the slide bar 521 to slide through the sliding hole and squeeze the first spring 522. During this process, the vibration mechanism 53 will operate to generate vibration, causing the soil clods on the bulldozer plate 52 and the soil clods on the soil breaking block 43 to be shaken off. When the slider 512 slides from the third guide rail 313 to the second guide rail 312, the slide plate 51 will reset and slide away from the bulldozer plate 52, causing the first spring 522 to reset. Then, when the slider 512 slides from the second guide rail 312 to another third guide rail 313, the soil cleaning component 5 will slide back to the root of the guide plate 42 as the slider 512 slides. Then the slider 512 continues to slide to the first guide rail 311, and so on, so that the soil cleaning component 5 can slide back and forth along the guide plate 42 and clean the soil clods on the guide plate 42 and the soil breaking block 43, thereby ensuring that the trenching mechanism 4 can always maintain good trenching efficiency.

[0048] S3. When the soil clearing component 5 slides to the end of the guide plate 42 and contacts the soil breaking block 43, the sliding plate 51 continues to slide, causing the push rod 532 and the push plate 533 to slide into the sliding cavity and push the deflection plate 535 to deflect. When the push plate 533 disengages from the deflection plate 535, the second spring 537 drives the deflection plate 535 to strike the bulldozing plate 52, causing the bulldozing plate 52 to vibrate and transmit the vibration to the soil breaking block 43 and the guide plate 42.

[0049] Specifically, when the sliding plate 51 slides so that the sliding rod 521 passes through the sliding hole and squeezes the first spring 522, the push rod 532 will slide into the sliding cavity. Since the push rod 532 is provided with push plates 533 at intervals, the push plates 533 will contact the deflection plate 535 extending into the sliding cavity. The deflection plate 535 is deflected, and during the deflection process, the deflection plate 535 will compress the second spring 537 to store energy. After the push plate 533 is separated from the deflection plate 535, the second spring 537 will instantly drive the deflection plate 535 to reset and cause the striking block 536 to hit the bulldozer plate 52, causing the bulldozer plate 52 to vibrate and shake off the soil on its surface. At the same time, since the bulldozer plate 52 is in contact with the soil breaking block 43, the vibration force will be transmitted to the soil breaking block 43 and the guide plate 42, causing the soil breaking block 43 and the guide plate 42 to vibrate as well, thereby further shaking off the soil on the soil breaking block 43 and the guide plate 42, which effectively improves the soil clearing effect of the soil clearing component 5 and further ensures that the soil breaking block 43 and the guide plate 42 have a good trenching effect.

[0050] S4. By arranging the first sleeve 61 and the second sleeve 62 in front and behind, two application pipes 6 with adjustable height are installed. Manure is applied to the bottom of the ditch through the application pipe 6 connected to the first sleeve 61, while carbon is applied above the manure layer through the other application pipe 6, so that a layered structure of manure at the bottom and carbon at the top is formed in the ditch.

[0051] This targeted, stratified application technology creates an ideal microenvironment in the soil where manure and carbon are closely adjacent, greatly promoting the activity efficiency of microorganisms, effectively reducing nitrogen volatilization and leaching, improving nutrient utilization, and significantly enhancing the soil's carbon sequestration capacity.

[0052] S5. Using the two V-shaped soil covering plates 26, the excavated soil is refilled into the ditch, and covered with manure and carbon materials to complete the targeted carbon supplementation operation.

[0053] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

6. A method for targeted carbon supplementation of manure in the topsoil, comprising using a targeted carbon supplementation device for manure in the topsoil as described in claim 5, characterized in that, Includes the following steps; S1. Install the mounting base (1) on the traction mechanism, and at the same time drive the hydraulic cylinder (11) to adjust the working height of the entire device according to the fertilization requirements. Adjust the height of the depth limiting wheel (24) and the soil covering plate (26) through the first hydraulic telescopic rod, and set the trenching depth and soil covering effect. S2. The device is pulled forward by the traction mechanism, and the trenching mechanism (4) is driven to rotate to dig trenches. At the same time, the rotation of the trenching mechanism (4) can drive the soil cleaning component (5) to slide along the guide groove (31), so that the soil cleaning component (5) slides back and forth along the guide plate (42) to clean the soil clods on the guide plate (42). S3. When the soil clearing component (5) slides to the end of the guide plate (42) and contacts the soil breaking block (43), the sliding plate (51) continues to slide, so that the push rod (532) and the push plate (533) slide into the sliding cavity and push the deflection plate (535) to deflect. When the push plate (533) disengages from the deflection plate (535), the second spring (537) drives the deflection plate (535) to strike the bulldozing plate (52), so that the bulldozing plate (52) vibrates and transmits the vibration to the soil breaking block (43) and the guide plate (42). S4. By arranging the first sleeve (61) and the second sleeve (62) in front and behind, two application pipes (6) with adjustable height are installed. The manure is applied to the bottom of the ditch through the application pipe (6) connected to the first sleeve (61), and carbon is applied to the manure layer through the other application pipe (6), so that a layered structure of manure at the bottom and carbon at the top is formed in the ditch. S5. Using the two V-shaped soil covering plates (26), the excavated soil is refilled into the ditch, covered with manure and carbon materials, to complete the targeted carbon supplementation operation.
