Description

Technical Field

[0001] This invention relates to the field of ecological planting technology, specifically to a carbon sequestration and carbon sink enhancement planting method and system based on an ecological model. Background Technology

[0002] Plant photosynthesis uses carbon dioxide as its core raw material. Its supply efficiency, concentration stability, and matching degree with the growth needs of seedlings directly determine the carbon sequestration effect of the planting system. At present, although planting-based carbon sequestration technology has been applied to facility agriculture, ecological restoration and other scenarios, there are fundamental technical bottlenecks in the coordination and dynamic adaptability of carbon dioxide regulation and the movement of planting institutions. This results in low carbon sequestration efficiency, serious waste of resources, and difficulty in meeting the demand for efficient, low-consumption, and stable carbon sequestration and enhancement. Among them, the problem of carbon dioxide supply and emission being completely disconnected from the movement of planting institutions and lacking a dynamic adaptation mechanism is the core bottleneck restricting the carbon sequestration and enhancement effect. In existing technologies, the carbon dioxide supply and emission modes of plant planting carbon sequestration systems generally adopt a fixed and unidirectional design, and are completely independent of the movement state of the planting mechanism, such as changes in the spacing between planting pots and positional movement, without establishing a collaborative control logic based on the spatial position of the planting pots and the growth needs of the seedlings. Based on this, the present invention provides a carbon sequestration and carbon sink enhancement planting method and system based on an ecological model to solve the problems mentioned in the background art. Summary of the Invention

[0003] This invention addresses the technical problems existing in the prior art by providing a carbon sequestration and enhancement planting method and system based on an ecological model. This solves the problem that in the prior art, the carbon dioxide supply and emission mode of plant planting carbon sequestration systems generally adopts a fixed and unidirectional design, and is completely independent of the movement state of the planting mechanism, such as changes in the spacing between planting pots and positional movement, without establishing a collaborative control logic based on the spatial position of the planting pots and the growth needs of the seedlings.

[0004] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A carbon sequestration and sink enhancement planting method based on an ecological model, comprising the following steps: SS1, system startup, the servo motor on the frame drives the inner shaft and outer shaft to rotate independently through two synchronous toothed belts respectively. The inner shaft drives the rotating frame with four planting mechanisms in the circumference to rotate, and the outer shaft drives the active bevel gear to rotate. SS2, bidirectional sliding, the active bevel gear drives the horizontal shaft to rotate, and the horizontal shaft synchronously drives the first reciprocating module and the second reciprocating module to move. The first reciprocating module drives the hanger to slide horizontally back and forth, and the second reciprocating module drives the adjustable pressure seat to slide vertically back and forth. SS3, Composite Motion: The horizontal axis drives the fixed axis to rotate through the second bevel gear. The fixed axis and the movable axis slide together to make the movable axis rotate synchronously and move vertically with the adjustable pressure seat. The movable axis drives the coupling in the seedling module, which drives the planting pot made of coconut coir composite substrate to rotate, realizing the horizontal and vertical composite motion of the planting pot. SS4 Monitoring: The carbon dioxide concentration sensor monitors the carbon dioxide concentration at the connection between the multi-channel hose and the seedling rack guide cavity in real time, and the visual detection module transmits the seedling growth data to the central control unit. SS5, central control and regulation: when the spacing between planting pots is at its maximum, the airflow conversion module supplies carbon dioxide under positive pressure; when the spacing between planting pots is at its minimum, it recovers residual carbon dioxide under negative pressure. The servo motor parameters are adjusted according to the seedling growth stage to optimize the coordination rhythm between motion and carbon dioxide supply and exhaust.

[0005] Based on the above technical solution, the present invention can be further improved as follows.

[0006] As a preferred technical solution of the present invention, a carbon sequestration and carbon sink enhancement planting system based on an ecological model applies the carbon sequestration and carbon sink enhancement planting method based on an ecological model described above. The system includes a frame, on which a central control unit, a visual detection module, an electrically controlled rotating frame, and an active bevel gear are provided. The rotating frame is provided with four planting mechanisms. The planting mechanism includes a multi-channel hose, three seedling modules, a horizontal shaft rotatably connected to a rotating frame, and a hanging frame slidably connected to the rotating frame. The horizontal shaft is driven by an active bevel gear and is equipped with a first reciprocating module and a second reciprocating module. A fixed shaft is rotatably mounted on the hanging frame and is slidably connected to an adjustable pressure seat. When the horizontal shaft rotates, the first reciprocating module drives the hanging frame to slide horizontally back and forth, and the second reciprocating module drives the adjustable pressure seat to slide vertically back and forth. A movable shaft is rotatably mounted on the adjustable pressure seat, and both the movable shaft and the fixed shaft are linked to the horizontal shaft. The seedling module includes a seedling rack slidably connected to a hanging frame. A coupling and a planting pot are rotatably mounted on the seedling rack. The coupling is driven by a movable shaft. Synchronous gears are installed on both the planting pot and the coupling. The two synchronous gears mesh with each other.

The flow guide cavity is connected to a multi-channel hose, and a carbon dioxide concentration sensor is installed at the connection between the two. Return springs are installed on the hanger and at the positions between each pair of seedling racks, as well as at the positions between the adjusting pressure seat and the adjacent seedling rack. It also includes an airflow conversion module, which is used for negative pressure discharge or positive pressure supply of carbon dioxide in the multi-channel hose.

[0007] As a preferred technical solution of the present invention, a servo motor is mounted on the frame, and two synchronous toothed belts are driven to the output shaft of the servo motor. An inner shaft is rotatably mounted on the frame, and the top end of the inner shaft is fixedly connected to the rotary frame. An outer shaft is rotatably sleeved on the inner shaft. The two synchronous toothed belts are driven to the inner shaft and the outer shaft respectively. The driving bevel gear is fixedly mounted on the outer shaft.

[0008] As a preferred technical solution of the present invention, the first reciprocating module includes a passive bevel gear mounted on a horizontal shaft, the passive bevel gear being connected to an active bevel gear, a reciprocating screw being rotatably connected to the rotary frame, a torsion spring being provided at the rotatable connection between the reciprocating screw and the rotary frame, a reciprocating gear being mounted on the reciprocating screw, and a half-tooth gear being mounted on the horizontal shaft, the half-tooth gear being meshed with the reciprocating gear.

[0009] As a preferred technical solution of the present invention, the second reciprocating module includes a hollow shaft and a wheel axle rotatably connected to the hanger. The hollow shaft has a first hexagonal hole that is slidably connected to the horizontal shaft. The cross-section of the first hexagonal hole and the horizontal shaft are both regular hexagons. A first bevel gear is installed on both the hollow shaft and the wheel axle. The two first bevel gears mesh orthogonally. A cam is installed on the wheel axle. A driven wheel is rotatably installed on the adjusting pressure seat. The outer wheel surface of the cam makes rolling contact with the contour of the driven wheel.

[0010] As a preferred technical solution of the present invention, a second bevel gear is installed on both the fixed shaft and the hollow shaft, and the two second bevel gears mesh orthogonally. The movable shaft has a shaft groove with an open top and slidingly connected to the fixed shaft. The cross-sections of the shaft groove and the fixed shaft are both regular hexagonal.

[0011] As a preferred technical solution of the present invention, the airflow conversion module includes a valve cylinder rotatably sleeved on an outer shaft and a valve cavity opened in the outer shaft. A valve ring is rotatably installed on the valve cavity. Each multi-channel hose is connected to the valve cavity through the valve ring, and a solenoid valve is provided at the connection between each multi-channel hose and the valve cavity. The electrical control terminal of the solenoid valve is connected to the central control unit for data transmission. Air vents are opened on the outer shaft at positions corresponding to the valve cylinder and the valve cavity. A carbon dioxide inlet pipe and a carbon dioxide outlet pipe are symmetrically installed on the valve cylinder.

[0012] As a preferred technical solution of the present invention, in the planting mechanism, the coupling in the uppermost seedling module is fixedly connected to the movable shaft, and the coupling in the middle and lowermost seedling modules is provided with a second hexagonal hole. A square segment is fixedly provided on the movable shaft. The second hexagonal hole is slidably connected to the square segment, and the cross-section of the second hexagonal hole and the square segment are both regular hexagons.

[0013] As a preferred embodiment of the present invention, the bottom of the planting pot is evenly distributed with mesh holes, and the planting pot is a breathable container pressed from a coconut coir composite substrate molding board.

[0014] As a preferred technical solution of the present invention, the visual detection module includes three visual probes installed on the frame. The data terminals of the three visual probes are all connected to the central control unit, and the axes of the three visual probes are all perpendicular to the axis of the planting pot.

[0015] The beneficial effects of this invention are: 1. In response to the problem that the carbon dioxide supply and exhaust modes in existing plant planting carbon sequestration systems are fixed and unidirectional, and that they are completely independent of the movement of the planting pots, such as changes in spacing and position, and lack a dynamic adaptation mechanism, this invention constructs a coordinated control logic for movement state, supply and demand rhythm, and growth requirements through multi-component linkage. Specifically, the servo motor drives the inner and outer shafts to rotate independently through dual synchronous toothed belts. The inner shaft drives the rotating frame and planting mechanism to rotate, while the outer shaft drives the active bevel gear to trigger the horizontal shaft linkage. The horizontal shaft, through the first reciprocating module and the second reciprocating module, precisely controls the planting pots to achieve a composite movement of horizontal reciprocating sliding, vertical reciprocating sliding, and rotation, so that the spacing between the planting pots changes periodically. The central control unit dynamically adjusts the airflow conversion module based on real-time data from the carbon dioxide concentration sensor and the spacing between the planting pots. When the spacing between the planting pots is at its maximum, positive pressure is triggered to supply carbon dioxide, ensuring that the carbon dioxide reaches the area around the seedling leaves and eliminating absorption blind spots. When the spacing between the planting pots is at its minimum, negative pressure is activated to recover residual carbon dioxide, avoiding waste and respiratory inhibition. This coordinated mechanism, in which the movement state of the mechanism is directly related to the supply and exhaust modes, changes the drawbacks of the existing technology of fixed supply and exhaust that is unrelated to movement, thereby improving the efficiency of carbon dioxide supply and significantly increasing carbon sequestration efficiency compared to the traditional fixed mode, thus solving the problem that restricts the effect of carbon sequestration and carbon sink enhancement.

[0016] 2. Existing fixed planting mechanisms often lead to uneven light and air exposure for seedlings and cannot adjust environmental adaptability according to growth stages. This invention achieves a differentiated advantage through the multi-dimensional composite movement of the planting pot and its dynamic adaptation design to different growth stages. On one hand, the horizontal axis drives the first reciprocating module to slide the hanger horizontally, while the second reciprocating module drives the adjustable pressure seat to slide vertically. Simultaneously, the hexagonal sliding cooperation between the fixed and movable axes enables the planting pot to rotate synchronously. This composite movement of horizontal, vertical, and rotation allows all parts of the seedling to be evenly exposed to light and carbon dioxide airflow, avoiding the problems associated with traditional fixed planting methods. The design addresses issues of localized shading and insufficient oxygen, leading to increased photosynthetic pigment content and significantly enhanced long-term carbon sequestration capacity. Furthermore, a visual detection module collects real-time seedling growth data, which the central control unit uses to adjust servo motor parameters. During the seedling stage, the spacing between planting pots is reduced, decreasing the carbon dioxide supply and focusing on promoting root development through gentle shaking. During the growing season, the spacing is increased, extending the carbon supply time at maximum spacing to match the photosynthetic needs of the leaves. This dynamic adjustment of motion parameters according to growth stages, unlike the one-size-fits-all fixed approach of existing technologies, maintains optimal carbon sequestration efficiency throughout the seedling lifecycle.

[0019] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0020] The present invention provides the following preferred embodiments. like Figure 1-9 As shown, a carbon sequestration and sink enhancement planting method based on an ecological model includes the following steps: SS1, system start-up, servo motor 2 on frame 1 drives inner shaft 4 and outer shaft 3 to rotate independently through two synchronous toothed belts respectively. Inner shaft 4 drives rotary frame 5 with four planting mechanisms in the circumference to rotate, and outer shaft 3 drives active bevel gear to rotate. SS2, bidirectional sliding, the active bevel gear drives the horizontal shaft 6 to rotate, the horizontal shaft 6 synchronously drives the first reciprocating module and the second reciprocating module to move, the first reciprocating module drives the hanger 7 to slide horizontally back and forth, and the second reciprocating module drives the adjustable pressure seat 8 to slide vertically back and forth; SS3, compound motion: the horizontal axis 6 drives the fixed axis 9 to rotate through the second bevel gear. The fixed axis 9 and the movable axis 10 slide together to make the movable axis 10 rotate synchronously and move vertically with the adjusting pressure seat 8. The movable axis 10 drives the coupling 11 in the seedling module to rotate the planting pot 12 made of coconut coir composite substrate, realizing the horizontal and vertical compound motion of the planting pot 12. SS4, monitoring: Carbon dioxide concentration sensor 13 monitors the carbon dioxide concentration at the connection between multi-channel hose 14 and seedling rack 15 guide cavity in real time; visual detection module 16 transmits seedling growth data to central control unit 17. SS5, central control and regulation: when the spacing between the 12 planting pots is at its maximum, the airflow conversion module supplies carbon dioxide under positive pressure; when the spacing between the 12 planting pots is at its minimum, it recovers residual carbon dioxide under negative pressure. The parameters of the servo motor 2 are adjusted according to the seedling growth stage to optimize the rhythm of motion and carbon dioxide supply and exhaust.

[0021] A carbon sequestration and carbon sink enhancement planting method system based on an ecological model includes a frame 1, on which a central control unit 17, a vision detection module 16, an electrically controlled rotating frame 5, and an active bevel gear are provided. A servo motor 2 is mounted on the frame 1. Two synchronous toothed belts are connected to the output shaft of the servo motor 2. An inner shaft 4 is rotatably mounted on the frame 1. The top end of the inner shaft 4 is fixedly connected to the rotary frame 5. An outer shaft 3 is rotatably sleeved on the inner shaft 4. The two synchronous toothed belts are respectively connected to the inner shaft 4 and the outer shaft 3. The active bevel gear is fixedly mounted on the outer shaft 3. Servo motor 2 drives the inner shaft 4 and outer shaft 3 to rotate independently via two synchronous toothed belts: The inner shaft 4 drives the rotating frame 5 to achieve electrically controlled rotation, which allows the four planting mechanisms on the rotating frame 5 to receive light and carbon dioxide supply evenly, avoiding uneven growth environment for local seedlings; The outer shaft 3 drives the active bevel gear to rotate stably, providing a continuous and controllable driving force for the horizontal shaft 6; This dual-axis independent transmission structure solves the problem of mutual interference between rotation and drive in traditional single-axis transmission. It not only ensures the overall coordination of the planting mechanism, but also allows for precise control of rotation speed and drive torque by adjusting two parameters of the servo motor, adapting to the growth needs of different seedlings and laying an environmental foundation for uniform carbon fixation of seedlings. At the same time, it simplifies the complex layout of multiple power sources and improves the system integration. The rotating frame 5 has four planting mechanisms evenly arranged around its circumference; The planting mechanism includes a multi-channel hose 14, three seedling modules, a horizontal shaft 6 rotatably connected to a rotating frame 5, and a hanging frame 7 slidably connected to the rotating frame 5. The horizontal shaft 6 is driven by an active bevel gear. The horizontal shaft 6 is equipped with a first reciprocating module and a second reciprocating module. A fixed shaft 9 is rotatably mounted on the hanging frame 7 and is slidably connected to an adjustable pressure seat 8. When the horizontal shaft 6 rotates, the first reciprocating module drives the hanging frame 7 to slide horizontally back and forth, and the second reciprocating module drives the adjustable pressure seat 8 to slide vertically back and forth. A movable shaft 10 is rotatably mounted on the adjustable pressure seat 8. Both the movable shaft 10 and the fixed shaft 9 are linked to the horizontal shaft 6. After the horizontal shaft 6 is driven to rotate by the active bevel gear, it will synchronously drive the first reciprocating module and the second reciprocating module to operate. The first reciprocating module drives the hanger 7 to slide horizontally back and forth along the rotating frame 5, thereby driving the seedling module on it to move horizontally. The second reciprocating module pushes the adjusting pressure seat 8 to slide vertically back and forth along the hanger 7. At the same time, under the linkage of the fixed shaft 9 and the horizontal shaft 6, the movable shaft 10 moves vertically with the adjusting pressure seat 8 and maintains stable rotation, ultimately realizing the composite movement of the seedling module in both horizontal and vertical directions, and providing continuous rotational power for the planting pot 12. The combined movement of the seedling module allows seedlings to be evenly exposed to light and airflow, solving the problem of uneven light and air exposure for seedlings in traditional fixed planting. The first reciprocating module includes a passive bevel gear mounted on the horizontal shaft 6, which is connected to the driving bevel gear. A reciprocating screw 21 is rotatably connected to the rotary frame 5. A torsion spring 22 is provided at the rotatable connection between the reciprocating screw 21 and the rotary frame 5. A reciprocating gear 24 is mounted on the reciprocating screw 21. A half-tooth gear 23 is mounted on the horizontal shaft 6, and the half-tooth gear 23 meshes with the reciprocating gear 24. When the horizontal shaft 6 rotates, the passive bevel gear meshes with the active bevel gear to transmit power, driving the half-tooth gear 23 to rotate synchronously; During the meshing stage of the half-tooth gear 23 and the reciprocating gear 24, the reciprocating screw 21 is driven to rotate and the torsion spring 22 stores force. After the half gear 23 disengages, the torsion spring 22 releases its elastic force, causing the reciprocating screw 21 to rotate in the opposite direction, thereby realizing the horizontal reciprocating sliding of the hanger 7; The second reciprocating module includes a hollow shaft 25 and a wheel axle 26 rotatably connected to the hanger 7. The hollow shaft 25 has a first hexagonal hole that is slidably connected to the horizontal shaft 6. The cross-section of the first hexagonal hole and the horizontal shaft 6 are both regular hexagons. A first bevel gear is installed on both the hollow shaft 25 and the wheel axle 26. The two first bevel gears mesh orthogonally. A cam 27 is installed on the wheel axle 26. A driven wheel 28 is rotatably installed on the adjusting pressure seat 8. The outer wheel surface of the cam 27 rolls in contact with the contour of the driven wheel 28. When the horizontal axis 6 rotates, the first hexagonal hole of the hollow shaft 25 and the horizontal axis 6 slide together, driving the hollow shaft 25 to rotate synchronously. The hollow shaft 25 transmits power to the wheel axle 26 through the orthogonally meshing first bevel gear. The wheel axle 26 drives the cam 27 to rotate, and the outer wheel surface of the cam 27 pushes the driven wheel 28 to roll, thereby driving the adjusting pressure seat 8 to slide vertically back and forth. Meanwhile, when the hanger 7 slides horizontally, the hollow shaft 25 can move horizontally along the transverse axis 6 to ensure that the power transmission is uninterrupted; In a preferred embodiment, the horizontal spacing of the planting pots 12 is adjustable in the range of 50-100mm, and the vertical spacing is adjustable in the range of 30-60mm. Compared with the electric push rod structure, the mechanical transmission method of cam 27 and driven wheel 28 has higher resistance to moisture and carbon dioxide corrosion, adapts to the complex working conditions of planting environment, and the movement rhythm is stable and controllable. A second bevel gear is installed on both the fixed shaft 9 and the hollow shaft 25. The two second bevel gears mesh orthogonally. The movable shaft 10 has a shaft groove with an open top and is slidably connected to the fixed shaft 9. The cross-sections of the shaft groove and the fixed shaft 9 are both regular hexagonal. When the hollow shaft 25 rotates, it drives the fixed shaft 9 to rotate synchronously through the meshing of the second bevel gear. The fixed shaft 9 is inserted into the regular hexagonal shaft groove of the movable shaft 10, which not only realizes torque transmission, but also allows the movable shaft 10 to slide vertically with the adjusting pressure seat 8. The seedling module includes a seedling frame 15 that is slidably connected to the hanger 7. A coupling 11 and a planting pot 12 are rotatably installed on the seedling frame 15. The bottom of the planting pot 12 is evenly distributed with mesh holes. The planting pot 12 is a breathable container pressed from a coconut coir composite substrate molding board. This coconut coir composite matrix molding board uses natural coconut coir as the main material, mixed with 5%-8% starch binder by mass and molded. The coconut coir composite substrate molding board has natural air permeability and biodegradability. It can work together with the mesh evenly distributed at the bottom of the planting pot 12 to form an efficient air and water permeable channel. It can achieve carbon retention through the biomass carbon of coconut coir itself, and optimize the growth environment of seedling roots to enhance the carbon sequestration capacity of plant photosynthesis. Moreover, it can be naturally degraded without carbon emission after disposal, while avoiding the environmental pollution and carbon lock-in problems of traditional plastic planting pots 12, further enhancing the carbon sequestration effect. The coupling 11 is driven by the movable shaft 10. Both the planting pot 12 and the coupling 11 are equipped with synchronous gears 18. The two synchronous gears 18 mesh with each other. The seedling rack 15 has a flow guide cavity and an array of air holes 19. The air holes 19 are connected to the flow guide cavity. The flow guide cavity is connected to the multi-channel hose 14. A carbon dioxide concentration sensor 13 is provided at the connection between the two. The array axis of the pores 19 is on the axis of the planting pot 12. The pores 19 are set on the outer ring edge of the planting pot 12. The height difference between the top surface of the pores 19 and the top surface of the planting pot 12 is 1cm-2cm. Return springs 20 are installed on the hanger 7 at the positions corresponding to each pair of seedling racks 15 and at the positions of the adjusting pressure seat 8 and the adjacent seedling rack 15. In the planting mechanism, the coupling 11 in the uppermost seedling module is fixedly connected to the movable shaft 10. The coupling 11 in the middle and lowermost seedling modules is provided with a second hexagonal hole. A square segment is fixedly provided on the movable shaft 10. The second hexagonal hole and the square segment are slidably connected, and the cross-section of the second hexagonal hole and the square segment are both regular hexagonal. When the movable shaft 10 rotates, the coupling 11 of the upper and lower seedling modules, being fixed to the movable shaft 10, rotates synchronously and drives the planting pot 12 to rotate. The coupling 11 of the middle and bottom seedling modules slides with the square section of the movable shaft 10 through the regular hexagonal second hexagonal hole, so that it can rotate synchronously with the movable shaft 10 and slide along the square section when the movable shaft 10 moves vertically. The three seedling modules ultimately achieve synchronized rotation and synchronized vertical adjustment. The visual inspection module 16 includes three visual probes mounted on the frame 1. The data terminals of the three visual probes are all connected to the central control unit 17, and the axes of the three visual probes are all perpendicular to the axis of the planting pot 12. Three vision probes can detect the seedling growth status from all angles, including but not limited to leaf size, color, and root development, avoiding blind spots and ensuring accurate data. After the detection data is transmitted to the central control unit 17, the central control unit can dynamically adjust the parameters of the servo motor 2, optimize the movement rhythm of the planting mechanism, and at the same time control the solenoid valve and valve ring 31 of the airflow conversion module. When the carbon dioxide concentration is insufficient, the solenoid valve opens to provide positive pressure. When there is excess carbon dioxide, it is discharged and recovered under negative pressure. This closed-loop system with visual detection and intelligent control solves the problem of fixed carbon dioxide supply in traditional planting, which cannot meet the growth needs of seedlings. It reduces carbon dioxide waste and ensures that seedlings grow at the optimal carbon dioxide concentration. Meanwhile, the airflow conversion module is integrated on the outer shaft 3. The rotation of the outer shaft 3 makes the air inlet 32 ​​evenly conduct carbon dioxide in the valve cylinder 29, ensuring that the air supply of the four planting units is consistent and improving the stability and efficiency of the system's carbon sequestration. It also includes an airflow conversion module, which is used for negative pressure discharge or positive pressure supply of carbon dioxide in the multi-channel hose 14.

[0022] The airflow conversion module includes a valve cylinder 29 rotatably mounted on an outer shaft 3 and a valve cavity 30 opened inside the outer shaft 3. A valve ring 31 is rotatably mounted on the valve cavity 30. Each multi-channel hose 14 is connected to the valve cavity 30 through the valve ring 31, and a solenoid valve is provided at the connection between each multi-channel hose 14 and the valve cavity 30. The electrical control terminal of the solenoid valve is connected to the central control unit 17. An air vent 32 is opened on the outer shaft 3 at an array corresponding to the positions between the valve cylinder 29 and the valve cavity 30. A carbon dioxide inlet pipe 33 and a carbon dioxide outlet pipe 34 are symmetrically mounted on the valve cylinder 29.

[0023] When carbon dioxide is supplied, the central control unit 17 controls the solenoid valve to open, and the external carbon dioxide enters the valve cylinder 29 through the carbon dioxide inlet pipe 33. The air vents 32 arranged in the array during the rotation of the outer shaft 3 continuously introduce carbon dioxide into the valve chamber 30, and then deliver it to the seedling module through the valve ring 31 and the solenoid valve. When excess carbon dioxide is discharged, it is discharged and recovered through the multi-channel hose 14, solenoid valve, valve chamber 30, and carbon dioxide discharge pipe 34. The array's vents 32 rotate in conjunction with the outer shaft 3 to ensure uniform carbon dioxide levels in the four planting units, thus solving the problem of localized excessive or insufficient airflow distribution in traditional systems.

[0024] The horizontal axis 6 rotates to drive the first and second reciprocating modules, causing the spacing between the two planting pots 12 to change back and forth, and the spacing is precisely coordinated with the carbon dioxide spray. The synergy between the mechanical action driven by the horizontal axis 6 and the carbon dioxide spray is essentially to achieve dynamic and precise matching of carbon dioxide supply and seedling absorption, solving the problems of uneven carbon dioxide concentration and insufficient absorption in traditional planting, and directly improving carbon fixation efficiency. When the spacing between the two planting pots 12 is at its maximum and the carbon dioxide concentration is lower than the preset value, carbon dioxide is supplied in a targeted manner, eliminating absorption blind spots. When the first reciprocating module drives the hanger 7 to slide horizontally and the second reciprocating module drives the adjustable pressure seat 8 to slide vertically, so that the spacing between the two planting pots 12 reaches its maximum, there are no leaves blocking the seedlings, and the effective area for photosynthesis is increased. At the same time, the stomata 19 on the outer edge of the planting pot 12 can directly spray carbon dioxide around the seedling leaves, and the open space formed by the maximized spacing allows carbon dioxide to diffuse evenly, avoiding the obstruction of airflow by adjacent support tubes, so that the carbon dioxide concentration around the seedlings is stably maintained in the optimal range for photosynthesis. The carbon dioxide absorption rate of a single seedling is improved compared with traditional fixed-spacing planting, and the amount of carbon sequestration per unit time is significantly increased.

[0025] When the spacing between two planting pots 12 is at its minimum and the carbon dioxide concentration is higher than the preset value, the residual carbon dioxide is recovered in a targeted manner to avoid waste and pollution. When the spacing between two planting pots 12 is reduced, the airtightness of the space between seedlings is enhanced, and the unabsorbed residual carbon dioxide is easy to accumulate locally. At this time, carbon dioxide recovery is started. On the one hand, the unused carbon dioxide can be recovered into the system circulation through the airflow conversion module, so as to improve the carbon dioxide utilization rate and reduce the amount of external carbon dioxide supplementation. On the other hand, it can prevent excessive carbon dioxide from inhibiting seedling respiration, ensuring normal physiological activities of seedlings and laying the foundation for subsequent continuous carbon fixation.

[0026] This collaborative action breaks through the traditional one-way carbon dioxide supply model. Through a closed-loop design of supply, recycling, and reuse, it upgrades carbon sequestration from passive supply to active circulation, creatively reducing carbon loss. The carbon dioxide recovered to enhance the sinking effect is filtered twice by the airflow conversion module and can be resupplied to the multi-channel hose 14 through the carbon dioxide inlet pipe to form a leak-free carbon dioxide circulation system. Compared to the traditional planting method where carbon dioxide is directly emitted into the atmosphere without being absorbed, this design can reduce carbon emissions; Meanwhile, the recovered carbon dioxide can be reused without additional purification, reducing energy consumption and carbon emissions during carbon dioxide production and transportation, and indirectly increasing the overall carbon dioxide sequestration contribution of the system.

[0027] When the first reciprocating module drives the hanger 7 to slide horizontally and the second reciprocating module drives the adjustable pressure seat 8 to slide vertically, it will cause the planting pot 12 to produce a slight horizontal and vertical combined sway. This shaking can stimulate the seedling roots to stretch out, improve the root system's absorption efficiency of nutrients in the coconut coir substrate, and make the plant stems thicker and the leaves more sturdy. At the same time, the leaves can be exposed to more light when slightly shaken, which increases the content of photosynthetic pigments and significantly enhances the long-term carbon fixation capacity.

[0028] At the same time, this coordinated action can be dynamically adjusted according to different growth stages of the seedlings; During the seedling stage, reduce the variation in the spacing between planting pots (12), decrease the carbon dioxide supply, and focus on promoting root development through gentle shaking. During the growing season, increase the range of spacing variation and extend the carbon dioxide supply time when the spacing is maximized to match the photosynthetic needs of the leaves. This precise matching of growth stages, actions, and carbon dioxide supply avoids the one-size-fits-all supply model in traditional planting, keeping the carbon sequestration efficiency of seedlings at the optimal level throughout the entire growth cycle.

[0029] The specific steps for using this invention are as follows: When the carbon sequestration and carbon sink enhancement planting system based on the ecological model of this invention is working, the servo motor 2 on the frame 1 first drives the inner shaft 4 and the outer shaft 3 to rotate independently through two synchronous toothed belts. The inner shaft 4 drives the rotating frame 5, which is uniformly set with four planting mechanisms in the circumference, to rotate electrically, ensuring that each planting mechanism receives light and subsequent carbon dioxide supply evenly. The outer shaft 3 drives the active bevel gear to provide a stable driving force for the horizontal shaft 6 in the planting mechanism. After the horizontal axis 6 rotates, on the one hand, the first reciprocating module drives the hanger 7 to slide horizontally back and forth along the rotating frame 5, and on the other hand, the second reciprocating module drives the adjusting pressure seat 8 to slide vertically back and forth along the hanger 7. At the same time, the horizontal axis 6 drives the fixed shaft 9 on the hanger 7 to rotate through the second bevel gear. The sliding cooperation between the fixed shaft 9 and the movable shaft 10 makes the movable shaft 10 rotate synchronously and move vertically with the adjusting pressure seat 8. The movable shaft 10 then drives the coupling 11 of the seedling module, which drives the planting pot 12, which is made of coconut coir composite substrate molding board and has a mesh on the bottom, to rotate, realizing the horizontal and vertical compound movement of the seedling module. The air guide cavity and array air holes 19 on the seedling rack 15 are connected to the airflow conversion module through the multi-channel hose 14. The carbon dioxide concentration sensor 13 at the connection between the multi-channel hose 14 and the air guide cavity monitors the carbon dioxide concentration near the planting pot 12 in real time. The three vision probes on the frame 1 transmit the seedling growth data to the central control unit 17. The central control unit 17 adjusts the parameters of the servo motor 2 to optimize the movement rhythm and controls the airflow conversion module accordingly. When the spacing between the planting pots 12 is at its maximum and the carbon dioxide concentration is lower than the preset value, the solenoid valve opens and carbon dioxide is supplied to the air hole 19 through the carbon dioxide inlet pipe 33, valve cylinder 29, outer shaft 3, air port 32, valve chamber 30, valve ring 31 and multi-channel hose 14. When the spacing between the planting pots 12 is at its minimum and the carbon dioxide concentration is higher than the preset value, negative pressure recovery is initiated. The residual carbon dioxide is recycled and circulated through the vent 19, multi-channel hose 14, solenoid valve, valve chamber 30 and drain pipe. The system can be dynamically adjusted according to the seedling stage, forming a closed-loop process of power transmission, compound motion, detection feedback, intelligent control and coordinated carbon dioxide supply and exhaust, so as to achieve precise carbon sequestration and enhancement.
