Description

Technical Field

[0001] This invention relates to the field of plant cultivation technology, and in particular to a method for simulating wild cultivation of Polygonatum sibiricum under forest cover. Background Technology

[0002] As an important medicinal and edible herb, Polygonatum has the effects of replenishing qi and nourishing yin, strengthening the spleen and moistening the lungs, and its market demand is increasing. Wild Polygonatum resources are becoming increasingly depleted due to over-harvesting, and artificial cultivation has become the main supply method.

[0003] However, traditional artificial cultivation methods often involve continuous field cropping and long-term use of chemical fertilizers and pesticides, leading to soil compaction, increased pests and diseases, and a decline in the quality of Polygonatum, making it difficult to achieve the medicinal efficacy standards of wild Polygonatum. Furthermore, Polygonatum seeds experience morphological and physiological dormancy, resulting in low germination rates and uneven emergence under natural conditions, and a long seedling cycle. In addition, the complex terrain under forest cover makes weed management, pest control, and water and fertilizer regulation difficult and costly. Therefore, a semi-wild cultivation method for Polygonatum under forest cover is proposed. Summary of the Invention

[0004] Based on the aforementioned technical problems, this invention proposes a method for semi-wild cultivation of Polygonatum sibiricum under forest cover.

[0005] The present invention proposes a method for semi-wild cultivation of Polygonatum sibiricum under forest cover, comprising the following steps:

[0006] S1. Edible fungi are cultivated under the forest. After the edible fungi are harvested, the residual mycelial network and organic matter are used to form a fungal residue layer to naturally improve the forest soil. The forest soil is then divided into multiple equidistant semi-buried modular simulated wild planting troughs.

[0007] S2. The seeds of Polygonatum were subjected to alternating temperature stratification, mechanical peeling, and cold storage germination treatment in sequence. The treated seedlings were then evenly coated with 5%-8% fire ash to prevent diseases and promote root development.

[0008] S3. Place the coated seedlings under artificial forests at an altitude of 1000-1500m for domestication and seedling cultivation. The seedling cultivation period is 30-45 days to obtain domesticated seedlings.

[0009] S4. Transplant the domesticated seedlings into modular, semi-wild planting troughs that have undergone soil improvement treatment.

[0010] S5. Insect-attracting and insect-killing devices are used for pest control, and the height of weeds is controlled by a weed-cutting mechanism to retain weeds and conserve water and soil.

[0011] Preferably, the planting trough in S1 is a multi-layered soil structure. From top to bottom, the planting trough includes a biomimetic surface covering layer, a planting substrate layer, a moisture-retaining buffer layer, a drainage layer, and an isolation layer. The biomimetic surface covering layer is composed of 20% pine needles, 30% fallen leaves, 20% rice husks, and 30% wood chips. The planting substrate layer is composed of 30% humus, 30% fungal residue, 30% native forest soil, and 10% perlite. The moisture-retaining buffer layer includes a moisture-retaining pad composed of coconut coir and peat moss, absorbent felt, and capillary ropes for upward water diversion. The drainage layer includes a drainage layer composed of gravel, expanded clay, and coarse sand, and a drainage pipe. The lower end of the capillary rope extends to the bottom of the drainage layer. The drainage pipe has openings on its side. The isolation layer is a geotextile laid below the drainage layer.

[0012] Through the above technical solutions, the multi-layered soil structure of the planting trough can accurately simulate the soil environment of wild Solomon's seal. The biomimetic surface covering layer retains moisture and suppresses weeds, the planting substrate layer provides simulated wild nutrition, the moisture-retaining buffer layer works with capillary ropes to regulate water, and the drainage layer prevents root rot.

[0013] Preferably, the variable temperature stratification treatment in S2 is a stratification treatment that simulates natural seasonal temperature changes, including: A1, selecting fresh, mature, and plump seeds and disinfecting them with 0.1% potassium permanganate; A2, mixing the disinfected seeds with moist sand at a ratio of 1:3 and placing them in an environment of 2-5℃ for 30-45 days; A3, then moving the seeds to an environment of 15-20℃ for 10-15 days to simulate the warming trend in early spring and complete the variable temperature stratification treatment.

[0014] The above technical solution utilizes variable temperature stratification treatment to break the morphological and physiological dormancy of Polygonatum seeds, thereby increasing the germination rate and shortening the seedling cycle.

[0015] Preferably, the insect-attracting and killing device in S5 includes a support frame, on which support plates are installed in a linear array on both sides of the support frame, and an insect-attracting box is fixedly connected to the lower surface of the support plates. An LED light fixture is fixedly installed on the inner top wall of the insect-attracting box.

[0016] Through the above technical solution, the light source of the LED lamp is a specific wavelength of 365-400nm, which is convenient for targeting the main pests of Polygonatum, thereby accurately attracting and killing pests, and reducing the harm to beneficial insects, thus leading the pests into the insect trap.

[0017] Preferably, an insect collection box is fixedly connected to the bottom of the insect trap, a fan is provided on the upper surface of the support plate, a rain cover is provided on the outer surface of the fan, the suction end of the fan is connected to the insect collection box through an exhaust pipe, a negative pressure pipe is connected between the insect collection box and the insect trap, and the end of the negative pressure pipe extending to the insect trap is set as a conical structure with a larger outer diameter and a smaller inner diameter.

[0018] The above technical solution utilizes a fan and exhaust pipe to generate negative pressure, drawing pests from the insect trap into the insect collection box through the negative pressure pipe to dry them. The rain cover prevents the fan from being damaged by direct contact with rainwater, and the conical structure at one end of the negative pressure pipe facilitates the rapid intake of pests.

[0019] Preferably, a filter screen is provided at one end of the exhaust pipe extending into the insect collection box, and push cylinders are symmetrically distributed on one side of the upper surface of the insect collection box. One end of the piston rod of the push cylinder extends into the insect collection box and is provided with a connecting plate. A scraper is fixedly connected to the side surface of the connecting plate near the filter screen.

[0020] The above technical solution utilizes the extension of the piston rod of the cylinder to drive the scraper downward to clean the filter screen.

[0021] Preferably, a door panel is hinged to one side surface of the insect collection box via a pin, a concave plate is fixedly installed on the outer surface of the insect collection box, a threaded rod is installed on the inner surface of the concave plate via a bearing, a stepper motor is fixedly installed on one side surface of the concave plate, one end of the output shaft of the stepper motor is fixedly sleeved to one end of the threaded rod via a coupling, a sliding block is threaded onto the surface of the threaded rod, the surface of the sliding block is slidably engaged with the inner wall of the concave plate, an electromagnet is embedded on one side surface of the sliding block and one end of the piston rod of the pushing cylinder, and the electromagnet is magnetically connected to the connecting plate.

[0022] Through the above technical solution, when the scraper approaches the sliding block, it pushes the electromagnet on the cylinder to disconnect, activates the electromagnet on the sliding block, and simultaneously starts the stepper motor. The rotation of the stepper motor output shaft drives the through screw connected to it to rotate. The rotation of the through screw drives the sliding block connected to it to move. The movement of the sliding block drives the connecting plate connected to it to move, thereby driving the scraper to move and pushing the dried pests towards the door panel, causing the door panel to open under force, thus cleaning the insect collection box.

[0023] Preferably, the mowing mechanism includes grass shears. A groove is formed on the surface of the support frame. A fully threaded screw is mounted on the inner wall of the groove via a bearing. A drive motor is formed on one side surface of the support frame. One end of the output shaft of the drive motor extends into the support frame and is fixedly connected to one end of the fully threaded screw via a coupling. A movable block is threaded onto the surface of the fully threaded screw. A mounting plate is provided on the lower surface of the movable block. A mounting groove is formed on the lower surface of the mounting plate. A through-threaded screw is mounted on the inner wall of the mounting groove via a bearing. A motor is fixedly mounted on one side surface of the mounting plate. One end of the machine's output shaft is fixedly sleeved to one end of the threaded screw via a coupling. A sliding member is threaded onto the surface of the threaded screw, and the surface of the sliding member slides against the inner wall of the mounting groove. Slide rails are symmetrically distributed on the lower surface of the mounting plate. The lower surface of the sliding member is fixedly connected to the sliders of the two slide rails via connectors. The hinge points of the two blades of the grass shears are mounted on the lower surface of the connector via bearings. Telescopic cylinders are symmetrically distributed on the lower surface of the connector via pins, and one end of the piston rod of the telescopic cylinder is hinged to the handle of the grass shears.

[0024] The above technical solution utilizes the rotation of the motor output shaft to drive the connected through-thread screw to rotate. The rotation of the through-thread screw causes the sliding member to move along the inner wall of the mounting groove. The movement of the sliding member, through the connecting member, causes the slider to move along the surface of the slide rail. The movement of the connecting member causes the grass shears to move closer to the weeds. Then, the extension and retraction of the piston rod of the telescopic cylinder controls the opening and closing action of the grass shears to trim the weeds in the planting trough. After trimming, the grass shears are reset. Then, the rotation of the drive motor output shaft drives the connected full-thread screw to rotate. The rotation of the full-thread screw causes the moving block to move along the inner wall of the groove. The movement of the moving block causes the grass shears to move, making it easier for the grass shears to move closer to the next planting trough to trim the weeds in the next planting trough.

[0025] Preferably, a driving gear and a driven gear are respectively mounted between the moving block and the mounting plate via bearings. The upper surface of the mounting plate is fixedly connected to the lower surface of the driven gear. The driving gear meshes with the driven gear. A servo motor is fixedly mounted on the upper surface of the bracket. One end of the output shaft of the servo motor extends into the bracket and is fixedly sleeved with the shaft center of the driving gear through a reduction gearbox.

[0026] Using the above technical solution, after the weeds in the planting trough on the same side are cleared, the servo motor is started. The rotation of the servo motor output shaft drives the drive gear connected to it to rotate. The rotation of the drive gear drives the driven gear meshing with it to rotate. The rotation of the driven gear drives the mounting plate to rotate, thereby causing the grass shears to change direction and trim the weeds in the planting trough on the other side.

[0027] Preferably, the upper surface of the bracket is provided with a solar power supply component, which includes solar panels, energy storage batteries, and a control module that are installed in a rectangular array on the upper surface of the bracket.

[0028] Through the above technical solution, the solar power supply component provides power to the lawn mowing mechanism and the insect trapping and killing device. The solar panel generates electricity efficiently, giving priority to charging the energy storage battery, while directly driving the LED lights and fan. Excess electricity is stored for backup. The control module executes the lawn mowing mechanism according to the remaining capacity of the energy storage battery.

[0029] The beneficial effects of this invention are as follows:

[0030] 1. By setting up semi-buried modular simulated wild planting troughs and adopting a multi-layered soil structure consisting of a surface biomimetic cover layer, a planting substrate layer, a moisture-retaining buffer layer, a drainage layer, and an isolation layer, a highly simulated forest micro-ecological environment is constructed, realizing the natural improvement and sustainable utilization of the soil, and effectively enhancing the quality and medicinal components of Polygonatum.

[0031] 2. By setting up variable temperature stratification treatment and high-altitude forest acclimatization seedling cultivation, the dormancy of Polygonatum seeds was effectively broken, the germination rate was improved, the seedling cultivation cycle was significantly shortened, and the seedlings' resistance to the native environment was enhanced.

[0032] 3. By setting up insect-attracting and insect-killing devices and weed-cutting devices, and combining them with solar power components, physical insect control and precise weed control are achieved, completely avoiding the use of chemical pesticides and herbicides, greatly reducing the cost of manual management, and realizing green, intelligent and efficient understory planting.

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0047] Reference Figures 1-12 A method for semi-wild cultivation of Polygonatum sibiricum under forest cover includes the following steps:

[0048] S1. Edible fungi are cultivated under the forest. After the edible fungi are harvested, the residual mycelial network and organic matter are used to form a fungal residue layer to naturally improve the forest soil. The forest soil is divided into multiple equidistant semi-buried modular simulated wild planting troughs 1.

[0049] S2. The seeds of Polygonatum were subjected to alternating temperature stratification, mechanical peeling and cold storage germination treatment in sequence. Then, the treated seedlings were evenly coated with 5%-8% fire ash to prevent diseases and promote root development.

[0050] S3. Place the coated seedlings under artificial forests at an altitude of 1000-1500m for acclimatization and seedling cultivation. The seedling cultivation period is 30-45 days to obtain acclimatized seedlings.

[0051] S4. Transplant the domesticated seedlings into the modular semi-wild planting trough 1 after soil improvement treatment;

[0052] S5. Insect-attracting and insect-killing devices are used for pest control, and the height of weeds is controlled by a weed-cutting mechanism to retain weeds and conserve water and soil.

[0053] like Figure 12 As shown, to accurately simulate the soil environment of wild Polygonatum, the planting trough 1 in S1 has a multi-layered soil structure. From top to bottom, the planting trough 1 includes a biomimetic surface cover layer 11, a planting substrate layer 12, a moisture-retaining buffer layer 13, a drainage layer 14, and an isolation layer 15. The biomimetic surface cover layer 11 is composed of 20% pine needles, 30% fallen leaves, 20% rice husks, and 30% wood chips. The planting substrate layer 12 is composed of 30% humus, 30% fungal residue, 30% native forest soil, and 10% perlite. The moisture-retaining buffer layer 13 includes a moisture-retaining pad 131 composed of coconut coir and peat moss, and an absorbent felt 132. The system includes a capillary rope 133 for upward water diversion, a drainage layer 14 consisting of a drainage layer 141 made of gravel, ceramsite, and coarse sand, and a drainage pipe 142. The lower end of the capillary rope 133 extends to the bottom of the drainage layer 141. The drainage pipe 142 has openings 143 on its side. The isolation layer 15 is a geotextile laid under the drainage layer 141. The multi-layer soil structure of the planting trough 1 can accurately simulate the soil environment of wild Solomon's seal. The surface biomimetic cover layer 11 retains moisture and suppresses weeds. The planting substrate layer 12 provides simulated wild nutrition. The moisture-retaining buffer layer 13 works with the capillary rope 133 to achieve water regulation. The drainage layer 141 prevents root rot.

[0054] By setting up a semi-buried modular simulated wild planting trough 1, and adopting a multi-layered soil structure consisting of a surface biomimetic cover layer 11, a planting substrate layer 12, a moisture-retaining buffer layer 13, a drainage layer 14, and an isolation layer 15, a highly simulated forest micro-ecological environment is constructed, realizing the natural improvement and sustainable utilization of the soil, and effectively enhancing the quality and medicinal components of Polygonatum.

[0055] To improve the germination rate, the variable temperature stratification treatment in S2 is a stratification treatment that simulates the temperature changes of the natural seasons, including: A1, selecting fresh, mature and plump seeds and disinfecting them with 0.1% potassium permanganate; A2, mixing the disinfected seeds with moist sand at a ratio of 1:3 and placing them in an environment of 2-5℃ for 30-45 days; A3, then moving the seeds to an environment of 15-20℃ for 10-15 days to simulate the warming of early spring and complete the variable temperature stratification treatment. The variable temperature stratification treatment breaks the morphological and physiological dormancy of Polygonatum seeds, improves the germination rate, and shortens the seedling cycle.

[0056] By setting up variable temperature stratification treatment and high-altitude forest acclimatization seedling cultivation, the dormancy of Polygonatum seeds was effectively broken, the germination rate was improved, the seedling cultivation cycle was significantly shortened, and the seedlings' resistance to the native environment was enhanced.

[0057] like Figures 1-6 As shown, in order to attract and kill pests, the insect-attracting and killing device in S5 includes a support 2. Support plates 21 are installed in a linear array on both sides of the support 2. An insect-attracting box 22 is fixedly connected to the lower surface of the support plate 21. An LED light 23 is fixedly installed on the inner top wall of the insect-attracting box 22. The light source of the LED light 23 is a specific wavelength of 365-400nm, which is convenient for targeting the main pests of Polygonatum, thereby accurately attracting and killing pests and reducing the damage to beneficial insects, and introducing pests into the insect-attracting box 22.

[0058] To kill the pests attracted to the insect trap 22, an insect collection box 24 is fixedly connected to the bottom of the insect trap 22. A fan 25 is installed on the upper surface of the support plate 21, and a rain cover 26 is installed on the outer surface of the fan 25. The suction end of the fan 25 is connected to the insect collection box 24 through the exhaust pipe 27. A negative pressure pipe 28 is connected between the insect collection box 24 and the insect trap 22. The end of the negative pressure pipe 28 extending to the insect trap 22 is set as a conical structure with a larger outer diameter and a smaller inner diameter. The negative pressure generated by the fan 25 and the exhaust pipe 27 draws the pests in the insect trap 22 into the insect collection box 24 through the negative pressure pipe 28 to dry them. The rain cover 26 prevents the fan 25 from being directly exposed to rainwater and damaged. The conical structure at one end of the negative pressure pipe 28 facilitates the rapid suction of pests.

[0059] To eliminate pests, a filter screen 29 is installed at one end of the exhaust pipe 27 extending into the insect collection box 24. A push cylinder 210 is symmetrically installed on one side of the upper surface of the insect collection box 24. One end of the piston rod of the push cylinder 210 extends into the insect collection box 24 and is fitted with a connecting plate 211. A scraper 212 is fixedly connected to the side surface of the connecting plate 211 near the filter screen 29. A door panel 218 is hinged to one side surface of the insect collection box 24 via a pin. A concave plate 213 is fixedly installed on the outer surface of the insect collection box 24. A threaded screw 214 is installed on the inner surface of the concave plate 213 via a bearing. A stepper motor 215 is fixedly installed on one side surface of the concave plate 213. One end of the output shaft of the stepper motor 215 is fixedly sleeved with one end of the threaded screw 214 via a coupling. A sliding block 216 is threaded onto the surface of the threaded screw 214. The surface of the sliding block 216 is flush with the inner surface of the concave plate 213. The sliding block 216 and the piston rod of the push cylinder 210 are both fitted with electromagnets 217. The electromagnets 217 are magnetically connected to the connecting plate 211. First, the extension of the piston rod of the push cylinder 210 drives the scraper 212 to move down to clean the filter screen 29. When the scraper 212 approaches the sliding block 216, the electromagnet 217 on the piston rod of the push cylinder 210 is disconnected, and the electromagnet 217 on the sliding block 216 is activated. At the same time, the stepper motor 215 is activated. The rotation of the output shaft of the stepper motor 215 drives the through screw 214 connected to it to rotate. The rotation of the through screw 214 drives the sliding block 216 connected to it to move. The movement of the sliding block 216 drives the connecting plate 211 connected to it to move, thereby driving the scraper 212 to move and push the dried pests towards the door panel 218, so that the door panel 218 is opened by force, thereby cleaning the insect collection box 24.

[0060] like Figure 1 and Figures 7-11As shown, for weed trimming, the lawnmower mechanism includes a grass shear 3. A groove 31 is formed on the surface of the support 2. A fully threaded screw 32 is mounted on the inner wall of the groove 31 via a bearing. A drive motor 33 is formed on one side surface of the support 2. One end of the output shaft of the drive motor 33 extends into the support 2 and is fixedly connected to one end of the fully threaded screw 32 via a coupling. A moving block 34 is threaded onto the surface of the fully threaded screw 32. A mounting plate 35 is provided on the lower surface of the moving block 34. A mounting groove 36 is formed on the lower surface of the mounting plate 35. The inner wall of the mounting plate 35 is fitted with a through-threaded screw 37 via a bearing. A motor 38 is fixedly mounted on one side surface of the mounting plate 35. One end of the output shaft of the motor 38 is fixedly connected to one end of the through-threaded screw 37 via a coupling. A sliding member 39 is threaded onto the surface of the through-threaded screw 37. The surface of the sliding member 39 slides against the inner wall of the mounting groove 36. Slide rails 310 are symmetrically distributed and embedded on the lower surface of the mounting plate 35. The lower surface of the sliding member 39 is fixedly connected to the sliders of the two slide rails 310 via connectors 311. The grass shears 3 have two blades. The hinge point of the blade is mounted on the lower surface of the connector 311 via a bearing. Telescopic cylinders 312 are symmetrically distributed on the lower surface of the connector 311 via pins. One end of the piston rod of the telescopic cylinder 312 is hinged to the handle of the grass shears 3. First, the rotation of the output shaft of the motor 38 drives the connected threaded screw 37 to rotate. The rotation of the threaded screw 37 causes the sliding member 39 to move along the inner wall of the mounting groove 36. The movement of the sliding member 39, through the connector 311, causes the slider to move along the surface of the slide rail 310. The movement of 1 causes the grass shears 3 to move closer to the weeds. Then, the extension and retraction of the piston rod of the telescopic cylinder 312 controls the opening and closing action of the grass shears 3 to trim the weeds in the planting trough 1. After trimming, the grass shears 3 returns to its original position. Then, the rotation of the output shaft of the drive motor 33 drives the full-thread screw 32 connected to it to rotate. The rotation of the full-thread screw 32 causes the moving block 34 to move along the inner wall of the groove 31. The movement of the moving block 34 causes the grass shears 3 to move, making it easier for the grass shears 3 to approach the next planting trough 1 and trim the weeds in the next planting trough 1.

[0061] To trim the weeds in the planting trough 1 on the other side, a drive gear 313 and a driven gear 314 are respectively installed between the moving block 34 and the mounting plate 35 via bearings. The upper surface of the mounting plate 35 is fixedly connected to the lower surface of the driven gear 314. The drive gear 313 meshes with the driven gear 314. A servo motor 315 is fixedly installed on the upper surface of the bracket 2. One end of the output shaft of the servo motor 315 extends into the bracket 2 and is fixedly sleeved with the shaft of the drive gear 313 through a reduction gearbox. After the weeds around the planting trough 1 on the same side are cleared, the servo motor 315 is started. The rotation of the output shaft of the servo motor 315 drives the drive gear 313 connected to it to rotate. The rotation of the drive gear 313 drives the driven gear 314 meshing with it to rotate. The rotation of the driven gear 314 drives the mounting plate 35 to rotate, thereby causing the grass shears 3 to change direction and trim the weeds in the planting trough 1 on the other side.

[0062] To achieve solar power supply, a solar power supply component 4 is installed on the upper surface of the support 2. The solar power supply component 4 includes solar panels arranged in a rectangular array on the upper surface of the support 2, an energy storage battery, and a control module. The solar power supply component 4 provides power to the mowing mechanism and the insect-attracting and killing device. The solar panels generate electricity efficiently, giving priority to charging the energy storage battery, and directly driving the LED lights and the fan 25. Excess electricity is stored for backup. The control module executes the mowing mechanism according to the remaining capacity of the energy storage battery.

[0063] By setting up insect-attracting and killing devices and weed-cutting devices, and combining them with solar power supply components 4, physical pest control and precise weed control are achieved, completely avoiding the use of chemical pesticides and herbicides, greatly reducing the cost of manual management, and realizing green, intelligent and efficient understory planting.

[0064] Working principle: During use, the solar panel receives sunlight during the day to generate direct current, which is used to charge the energy storage battery first. At night or on cloudy or rainy days, the energy storage battery switches to discharge mode to supply power to all loads. The rain cover 26 prevents the fan 25 from directly contacting rainwater.

[0065] The control module lights up the LED lamp 23. The light source of the LED lamp 23 attracts pests that target Solomon's seal into the insect trap 22. At the same time, the fan 25 is started. The pests that enter the insect trap 22 are sucked into the insect collection box 24 by the negative pressure pipe 28 and dried.

[0066] When cleaning is required, first, the solenoid valve of the push cylinder 2102 is energized, causing its piston rod to be magnetically connected to the connecting plate 211 via the electromagnet 217. The extension and retraction of the piston rod of the push cylinder 210 drives the scraper 212 to move up and down to clean the filter screen 29 via the connecting plate 211. After reciprocating 2-3 times, when the scraper 212 approaches the sliding block 216, the electromagnet 217 on the piston rod of the push cylinder 210 is disconnected, and the electromagnet 217 on the sliding block 216 is activated. At the same time, the stepper motor is activated. The stepper motor 215 rotates, causing the connected threaded screw 214 to rotate. The rotation of the threaded screw 214 causes the connected sliding block 216 to move. The movement of the sliding block 216 causes the connected connecting plate 211 to move, thereby causing the scraper 212 to move and push the dried pests towards the door panel 218, causing the door panel 218 to open under force, thereby cleaning the insect collection box 24. After cleaning is completed, the stepper motor 215 resets and pushes the cylinder 210 to retract.

[0067] When mowing is needed, the rotation of the output shaft of the motor 38 first drives the connected threaded screw 37 to rotate. The rotation of the threaded screw 37 drives the slide 39 to move along the inner wall of the mounting groove 36. The movement of the slide 39 drives the slider to move along the surface of the slide rail 310 through the connector 311. The movement of the connector 311 drives the grass shears 3 to move closer to the weeds. Then, the extension and retraction of the piston rod of the telescopic cylinder 312 controls the grass shears 3 to open and close, thereby trimming the weeds in the planting trough 1. After trimming, the grass shears 3 are reset. Then, the rotation of the output shaft of the drive motor 33 drives the connected threaded screw 32 to rotate. The rotation of the threaded screw 32 drives the moving block 34 to move along the inner wall of the groove 31. The movement of the moving block 34 drives the grass shears 3 to move, making it easier for the grass shears 3 to move closer to the next planting trough 1 to trim the weeds in the next planting trough 1.

[0068] After the weeds in the planting trough 1 on the same side are cleared, the servo motor 315 is started. The rotation of the output shaft of the servo motor 315 drives the drive gear 313 connected to it to rotate. The rotation of the drive gear 313 drives the driven gear 314 meshing with it to rotate. The rotation of the driven gear 314 drives the mounting plate 35 to rotate, thereby driving the grass shears 3 to change direction and trim the weeds in the planting trough 1 on the other side.

[0069] The above description is only 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.
