Description

Technical Field

[0001] This application relates to the field of soil control technology, and in particular to a control device for forestry soil pests and diseases. Background Technology

[0002] In forestry seedling cultivation, soil-borne diseases and pests are a key issue restricting tree growth quality and reducing seedling survival rates. Pathogens (such as root rot pathogens and damping-off pathogens), underground pests (such as grubs and cutworms), and insect eggs in the soil can damage seedling roots and compete for nutrients, leading to seedling wilting, stunted growth, and in severe cases, large-scale seedling failure, causing significant economic losses to forestry production. Therefore, before planting seedlings, it is necessary to control soil-borne diseases and pests in the planting area. Currently, the main methods for controlling soil-borne diseases and pests in forestry seedling cultivation fall into three categories: chemical pesticide control, physical and mechanical control, and biological control.

[0003] Traditional chemical pesticide control methods involve spraying or applying insecticides and fungicides (such as organophosphates and carbamates) to the soil to directly kill harmful organisms. However, this method leads to pesticide residues in the soil, which not only damages the soil's aggregate structure, causing soil compaction and decreased fertility, but also kills beneficial microorganisms in the soil (such as nitrogen-fixing bacteria and mycorrhizal fungi), disrupting the soil's ecological balance. Long-term use can create a vicious cycle where the more you try to control the problem, the worse it gets. Furthermore, pesticide residues can pollute groundwater through soil infiltration or accumulate in the food chain, harming birds and small mammals, posing risks to the surrounding ecological environment. This contradicts the current development concept of green and ecological forestry. In addition, some underground pests develop resistance to pesticides, requiring increasingly higher dosages, further exacerbating pollution and increasing costs.

[0004] Traditional physical and mechanical pest control methods include manual tilling and sun exposure, and high-temperature steam treatment. However, manual tilling and sun exposure rely on natural sunlight to heat the soil, which can only affect the top 5-10cm of soil and cannot cover the 5-30cm deep soil where pests are concentrated, resulting in incomplete eradication and high labor intensity. Although high-temperature steam treatment leaves no chemical residues, steam heating requires a large amount of electricity for water heating and steam transportation. Especially in low-temperature environments or when treating large areas of soil, energy costs increase significantly. In addition, the uniformity of steam heating is poor, and there is a tendency for local overheating to burn the soil or insufficient temperature in some areas to kill pests, resulting in low work efficiency and unsatisfactory pest control effects.

[0005] Traditional biological control methods involve introducing beneficial microbial agents into the soil, utilizing the competition and antagonism between microorganisms to inhibit the reproduction of harmful pathogens, or using natural enemies such as insect pathogens and nematodes to kill underground pests. While this method is environmentally friendly, it has limitations when used alone. On the one hand, if there are already a large number of pathogens or pests in the soil, single biological control is slow to take effect and cannot quickly control the spread of pests and diseases, easily missing the best time for prevention and control. On the other hand, the survival and reproduction of beneficial microorganisms are highly dependent on environmental conditions such as soil temperature and humidity. If the soil has not been pretreated (e.g., excessive residual heat after high-temperature insecticide treatment, or the presence of chemical pesticide residues), the survival rate of the microbial agents will decrease significantly, resulting in unstable control effects and failing to meet the dual requirements of rapid pest control and stable soil restoration for forestry seedling cultivation.

[0006] Existing devices for controlling soil pests and diseases in forestry are mostly single-method, independent applications, employing only one of the three methods: chemical pesticide control, physical and mechanical control, and biological control. They lack a comprehensive, coordinated design that integrates pest control, remediation, and maintenance. For example, some devices only target pests and diseases without considering subsequent soil ecological restoration; others focus solely on soil bioremediation technology without supporting efficient pest control methods, hindering the colonization of beneficial microorganisms. Even when a few devices attempt combined pest and disease control methods (such as chemical pest control followed by fungicide application), they require the use of two or more different control methods, operating independently and sequentially. This results in fragmented operations, high labor costs, and an inability to meet the efficient and convenient operational needs of seedling nurseries.

[0007] Therefore, we propose a control device for forestry soil pests and diseases to solve the above problems. Summary of the Invention

This improves the operational efficiency of forestry soil disease and pest control, and enhances the efficiency and effectiveness of killing pathogens, pests, and insect eggs in the soil. Furthermore, by evenly applying a microbial agent solution to the soil after heating and insecticidal treatment to replenish the microbial community, a dominant microbial community can be formed in the soil, inhibiting the recurrence of harmful organisms. Simultaneously, it restores the soil ecology, improves fertility, and provides a guarantee for subsequent forest seedling cultivation.

[0019] This application includes at least one of the following beneficial technical effects:

[0020] 1. This application utilizes a hydraulic cylinder to drive a heated insecticidal mechanism inserted into the soil. The drive assembly rotates the vertical shaft, main soil-crushing teeth, and secondary soil-crushing teeth, thoroughly breaking up the soil and dismantling the compacted soil layer. This allows heat to penetrate evenly into the deeper soil layers. Simultaneously, the electric heating component heats the vertical shaft, main soil-crushing teeth, and secondary soil-crushing teeth to 70℃-90℃, achieving soil heating and baking through heat conduction. The differentiated heating time of 10-35 minutes, tailored to varying soil moisture levels, effectively kills pathogens, pests, and insect eggs in the soil. The killing range covers the shallow to deep soil layers, avoiding the blind spots inherent in traditional chemical pesticide control. Compared to traditional chemical pesticide control, this device uses physical heating for insecticidal purposes, leaving no chemical residues and preventing damage to soil structure and pollution of the surrounding ecosystem. Furthermore, the controllable heating temperature of 70℃-90℃ maximizes the preservation of beneficial microorganisms and organic matter in the soil while killing harmful organisms, preventing soil fertility loss and meeting the stringent requirements of forest seedling cultivation for soil ecology.

[0021] 2. This application features a U-shaped stainless steel frame and an inverted triangular insert at the bottom, which can enclose the soil area to be treated, prevent pests from escaping due to heat, further improve the thoroughness of pest control, and allow the insect carcasses to decompose naturally into soil nutrients, achieving both pest control and fertilization.

[0022] 3. This application utilizes a microbial agent solution application mechanism, which can first comprehensively cool the soil after heating and insecticidal treatment, and then replenish the soil with microbial agent solution to quickly repair the soil microbial community, form a dominant beneficial bacterial community to inhibit the recurrence of harmful organisms, improve soil fertility, provide a high-quality soil environment for forest seedling cultivation, and help promote the root development of forest seedlings.

[0023] 4. This application features an L-shaped hanging pole that can stably support the mulch film roll. The combination of the movable plate, fixed plate, and locking nut not only limits the installation position of the mulch film roll, preventing it from sliding and shifting on the L-shaped hanging pole, but also facilitates the disassembly and replacement of the mulch film roll. After pest and disease control and the application of microbial inoculant solution in the soil, workers can manually cover the soil surface with film to retain moisture for 2-3 days, promoting the colonization of beneficial bacteria in the soil and laying the foundation for forest seedling cultivation.

[0024] 5. This application integrates the work processes of soil crushing, heating and insecticidal treatment, cooling, microbial remediation, and mulching and moisture retention through the synergistic action of the heating and insecticidal mechanism, the microbial agent solution application mechanism, and the mulch film roll. After heating and insecticidal treatment, the soil can be cooled quickly and comprehensively by blowing air into the soil through a suction fan, avoiding continuous damage to the soil from high temperatures. After cooling the soil, microbial agents can be applied comprehensively and efficiently. Finally, the biodegradable mulch film roll can be used to cover and moisturize the soil, promoting the colonization of beneficial bacteria. This forms an integrated pest management operation that sterilizes, remediates, and maintains the soil, eliminating the need for multiple pieces of equipment and significantly improving the operational efficiency of forestry soil pest and disease control.

[0042] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0043] First Embodiment

[0044] See Figures 1-9In the first embodiment of this application, the device for controlling forestry soil pests and diseases includes: a platform 1, a hydraulic cylinder 2 fixedly installed at the top center of the platform 1, a lifting plate 3 fixedly installed at the output shaft end of the hydraulic cylinder 2 through the platform 1, and a heating insect-killing mechanism 4 for killing pathogens, pests and insect eggs in the soil provided at the bottom of the lifting plate 3. The hydraulic cylinder 2 is used to control the vertical lifting and lowering of the lifting plate 3, thereby causing the heating insect-killing mechanism 4 to follow the vertical lifting and lowering of the lifting plate 3, so as to insert the heating insect-killing mechanism 4 into the soil for pest and disease control treatment of forest seedling soil. The heating insect-killing mechanism 4 includes multiple hanging columns 41, horizontal plates 42, multiple vertical shafts 43, and multiple soil-crushing main teeth. 44. Multiple soil-crushing teeth; 45. Electric heating assembly and drive assembly; multiple hanging columns 41 are detachably installed and fixed to the bottom of the lifting plate 3 in two rows. The hanging columns 41 can be fixed to the bottom of the lifting plate 3 by bolts. A horizontal plate 42 is fixedly installed at the bottom of the multiple hanging columns 41. Multiple vertical shafts 43 are rotatably installed at the bottom of the horizontal plate 42 and arranged in an array. Multiple soil-crushing main teeth 44 are fixedly installed on the peripheral surface of the multiple vertical shafts 43 and are evenly distributed. Multiple soil-crushing teeth 45 are fixedly installed on the bottom surface of the multiple soil-crushing main teeth 44 and are evenly distributed. The top ends of the multiple vertical shafts 43 all penetrate the horizontal plate 42. The electric heating assembly is used to heat the vertical shafts 43. The main crushing tooth 44 and the secondary crushing tooth 45 are heated. The electric heating assembly includes multiple mounting bases 47 and multiple electric heating tubes 48. The mounting bases 47 are fixedly installed on the bottom of the lifting plate 3 and arranged in an array. The mounting bases 47 are located directly above the corresponding vertical shaft 43. The multiple electric heating tubes 48 are fixedly installed on the bottom of the corresponding mounting bases 47. The bottom ends of the multiple electric heating tubes 48 extend into the corresponding heating chambers 46. The multiple electric heating tubes 48 are all adjustable temperature electric heating tubes of the same model, with a heating range of 70℃-90℃. The heat generated when the multiple electric heating tubes 48 are energized can be used to heat the corresponding vertical shaft 43 and the crushed soil on the vertical shaft 43. The main teeth 44 and the soil-breaking teeth 45 are heated to transfer heat to the soil, effectively heating and baking it to kill pathogens, pests, and insect eggs. For example, when heating soil with low humidity (10-15% moisture content, slightly dry soil) for pest and disease control, the heating time can be set to 10-15 minutes; when heating soil with suitable humidity (15-20% moisture content, can be formed into a clump when squeezed but does not crumble when released) for pest and disease control, the heating time can be set to 20-25 minutes; and when heating soil with high humidity (20-25% moisture content, slightly wet soil) for pest and disease control, the heating time can be set to 30-35 minutes.Furthermore, by employing electric heating to bake the soil, pest and disease control is achieved. This method effectively kills pests and diseases in the soil while maximizing the preservation of soil fertility and beneficial microorganisms. It is environmentally friendly and pollution-free, meeting the soil ecological requirements for forest seedling cultivation. The drive component controls the simultaneous rotation of multiple vertical shafts 43. By utilizing the multiple vertical shafts 43 to drive the rotation of their respective soil-breaking main teeth 44 and soil-breaking dividing teeth 45, the soil can be efficiently broken down. This ensures the efficiency and comprehensiveness of soil heating and baking, enhancing the elimination of pathogens in the soil. The efficiency and effectiveness in controlling pests and insect eggs are achieved through a drive assembly comprising multiple gears 411, multiple gears 412, multiple shaft seats 413, multiple drive shafts 414, multiple gears 415, a motor 416, and a gear 417. Multiple gears 411 are fixedly mounted on the vertical shafts 43 in the foremost row, and all gears 411 are located above the horizontal plate 42. The gears 411 mesh sequentially. Multiple gears 412 are fixedly mounted on their corresponding vertical shafts 43, and all gears 412 are located above the horizontal plate. Above 42, multiple bearing seats 413 are fixedly installed on the bottom of the lifting plate 3 and arranged in an array. Multiple drive shafts 414 are rotatably installed on the bottom of their respective bearing seats 413. Multiple gears 415 are fixedly sleeved on the bottom end of their respective drive shafts 414. Gears 412 and 415 in the same column are arranged alternately and mesh sequentially. The motor 416 is fixedly installed on the bottom of the lifting plate 3, and gear 417 is fixedly installed on the input of the motor 416. At the output shaft end, gear 417 meshes with one of the gears 411. Motor 416 controls the rotation of gear 417. Utilizing the meshing transmission between gear 417 and one of the gears 411, and in conjunction with the meshing transmission of multiple gears 411, the vertical shafts 43 in the front row can be controlled to rotate simultaneously. By utilizing the sequential meshing transmission of gears 412 and 415 in the same row, all vertical shafts 43 can rotate simultaneously, thus enabling comprehensive and efficient crushing and heating of the soil.

[0045] In this embodiment, a clearance hole is provided at the top center of the vehicle plate 1. The output shaft end of the hydraulic cylinder 2 passes through the clearance hole. The clearance hole is designed to facilitate the smooth extension and retraction of the output shaft end of the hydraulic cylinder 2. The top of the horizontal plate 42 has multiple mounting holes arranged in an array. Bearings are fixedly fitted on multiple vertical shafts 43. The outer rings of the multiple bearings are fixedly connected to the inner walls of the corresponding mounting holes. The bearing design ensures smooth and stable rotation of the vertical shafts 43. The bottom ends of the multiple vertical shafts 43 are all tapered. The tapered design of the bottom ends of the vertical shafts 43 facilitates the smooth insertion of the vertical shafts 43 into the soil. In the process, each of the multiple vertical shafts 43 has a heating chamber 46 with an open top. The hanging column 41, horizontal plate 42, multiple vertical shafts 43, multiple soil-crushing main teeth 44 and multiple soil-crushing dividing teeth 45 are all made of stainless steel. By using stainless steel for the hanging column 41, horizontal plate 42, multiple vertical shafts 43, multiple soil-crushing main teeth 44 and multiple soil-crushing dividing teeth 45, they have good mechanical strength and are not easily deformed or broken. This also gives the multiple vertical shafts 43, multiple soil-crushing main teeth 44 and multiple soil-crushing dividing teeth 45 good thermal conductivity, which can efficiently transfer heat to the soil.

[0046] In this embodiment, wear-resistant sealing rings 49 are fixedly installed on the bottom of multiple mounting bases 47, and the top ends of multiple vertical shafts 43 are respectively sealed and fitted with the bottom surface of the corresponding wear-resistant sealing rings 49. The design of the wear-resistant sealing rings 49 can effectively seal the heating chambers 46 inside the vertical shafts 43, ensuring that the heat generated by the electric heating tubes 48 is efficiently transferred to the soil through the soil-crushing main teeth 44 and soil-crushing dividing teeth 45 of the vertical shafts 43. The wear-resistant sealing rings 49 can be made of fluororubber or fluorosilicone rubber, which has the advantages of wear resistance, low thermal conductivity, and good high temperature resistance. Probe temperature sensors 410 are fixedly installed on the bottom of multiple mounting bases 47, and the bottom ends of multiple probe temperature sensors 410 extend into the corresponding heating chambers 46. Using the probe temperature sensors 410, the temperature of the corresponding heating chambers 46 can be monitored in real time. On the one hand, it is convenient to know the temperature value of the heat generated by the electric heating tubes 48. On the other hand, it is convenient to determine whether the probe temperature sensors 410 are working properly, providing convenience for subsequent maintenance and replacement of the probe temperature sensors 410.

[0047] In this embodiment, an exhaust pipe 418 is fixedly installed on the top of the horizontal plate 42, and a solenoid valve 419 is fixedly installed on the exhaust pipe 418. The design of the exhaust pipe 418 and the solenoid valve 419 facilitates the discharge of heat from the soil during subsequent soil cooling. A U-shaped stainless steel frame 5 is fixedly installed on the bottom of the horizontal plate 42. Multiple vertical shafts 43, multiple soil-breaking main teeth 44, and multiple soil-breaking dividing teeth 45 are all located within the U-shaped stainless steel frame 5. The bottom end of the exhaust pipe 418 penetrates the horizontal plate 42 and is located within the U-shaped stainless steel frame 5. The design of the U-shaped stainless steel frame 5 within the frame 5 is used to enclose the soil in the area where multiple soil-breaking teeth 45 and multiple soil-breaking main teeth 44 are located. During the process of heating and baking the soil in this area to kill pathogens, pests and insect eggs, it can prevent pests in the soil from crawling out of the area due to heat, thus intercepting the pests and further improving the killing effect. It can also leave the dead pests in the soil, and after the dead pests decompose, they can form fertilizer to provide nutrients for the seedlings.

[0048] In this embodiment, the bottom four sides of the U-shaped stainless steel frame 5 are welded with inverted triangular inserts 6. The design of the inverted triangular inserts 6 can improve the smoothness of the U-shaped stainless steel frame 5 being inserted into the soil. Since insect eggs and pests in the soil are generally concentrated in the soil layer at a depth of 5-30cm, the height of the U-shaped stainless steel frame 5 is set to 38-50cm, and the length of the vertical axis 43 inside the U-shaped stainless steel frame 5 is set to 33-36cm, thereby ensuring the complete eradication of insect eggs and pests in the soil.

[0049] In this embodiment, four legs 7 are fixedly installed at the bottom corners of the platform 1, and wheels 8 are rotatably installed at the bottom of each of the four legs 7. A handrail 9 is fixedly installed on the top right side of the platform 1. The design of the legs 7, wheels 8, and handrail 9 facilitates the movement of the device by hand. Four vertical guide rods 10 are fixedly installed on the top of the lifting plate 3 in two symmetrical rows. Four guide holes are opened on the top of the platform 1. The tops of the four vertical guide rods 10 slide through the corresponding guide holes. By utilizing the sliding connection between the vertical guide rods 10 and the guide holes, the movement direction of the lifting plate 3 can be guided to ensure that the lifting plate 3 rises and falls smoothly and vertically. A power supply box 11 located to the left of the hydraulic cylinder 2 is fixedly installed on the top of the platform 1. A battery pack 12 is fixedly installed inside the power supply box 11. A controller is fixedly installed on the side wall. The controller has a display screen and multiple control buttons. The hydraulic cylinder 2, multiple electric heating tubes 48, multiple probe temperature sensors 410, motor 416, solenoid valve 419, controller and battery pack 12 are electrically connected. The battery pack 12 is made of rechargeable lithium battery or battery. The battery pack 12 is used to supply power to the hydraulic cylinder 2, multiple electric heating tubes 48, multiple probe temperature sensors 410, motor 416, solenoid valve 419 and controller respectively. The temperature values ​​monitored by the multiple probe temperature sensors 410 can be displayed on the display screen. The multiple control buttons are used to control the hydraulic cylinder 2, multiple electric heating tubes 48, multiple probe temperature sensors 410, motor 416 and solenoid valve 419 to power and operate respectively.

[0050] In this embodiment, with the above structure, the forestry soil pest and disease control device provided in this application is used by the worker pushing the handle 9 to move the device forward in the seedling forest area. During the movement of the device, multiple electric heating tubes 48 can be turned on first. The multiple electric heating tubes 48 can heat the corresponding vertical shaft 43, soil crushing main teeth 44 and soil crushing dividing teeth 45 respectively until the heating and pest-killing mechanism 4 is aligned with the soil area to be treated. Then, the hydraulic cylinder 2 is activated to extend. The output shaft end of the hydraulic cylinder 2 drives the lifting plate 3 to move vertically downward. The four vertical guide rods 10 move along the corresponding vertical shafts 43 and 45. The guide holes slide synchronously to ensure the smooth movement of the lifting plate 3. During the downward movement of the lifting plate 3, the heating and insect-killing mechanism 4 at the bottom and the U-shaped stainless steel frame 5 move downward synchronously. The inverted triangular insert 6 at the bottom of the U-shaped stainless steel frame 5 inserts into the soil first, followed by the conical bottom of the vertical shaft 43. As the lifting plate 3 moves downward, the motor 416 is controlled to run. The motor 416 drives the gear 417 to rotate. By utilizing the meshing transmission between the gear 417 and one of the gears 411, and in conjunction with the sequential meshing of the multiple gears 411 in the front row, the vertical shaft 43 in the front row rotates simultaneously. By utilizing the sequential meshing of gears 412 and 415 in the same column, the remaining vertical shafts 43 can be driven to rotate simultaneously, thus causing all vertical shafts 43 to rotate synchronously. When the vertical shafts 43 rotate, the soil-breaking main teeth 44 and soil-breaking sub-teeth 45 on them also rotate, efficiently breaking up the soil in the soil entry area and breaking up the soil compaction layer. When the horizontal plate 42 is about to contact the ground, a gap of 2-3 cm is left between the horizontal plate 42 and the ground (to ensure that the bottom end of the exhaust pipe 418 is not blocked by soil), the operation of the hydraulic cylinder 2 is stopped, and the U-shaped stainless steel frame 5 is about to be fully inserted into the underground soil. At this time, as all the vertical shafts 43 drive the main soil-breaking teeth 44 and the dividing soil-breaking teeth 45 on them to rotate, the heat from all the vertical shafts 43, the main soil-breaking teeth 44 and the dividing soil-breaking teeth 45 is transferred to the broken soil. This achieves the effect of simultaneously breaking up the soil and heating and baking it, thus effectively killing pathogens, pests and insect eggs in the soil. Depending on the soil moisture (the staff can carry a soil moisture meter with the device to measure the soil moisture), the soil is heated and baked for an appropriate time. After the pests are killed, the multiple electric heating tubes 48 can be turned off.

The storage tank 131 is fixedly installed on the top of the vehicle platform 1 and located on the right side of the hydraulic cylinder 2. The storage tank 131 is used to hold the pre-prepared microbial agent solution. The microbial inoculant solution (e.g., mycorrhizal fungal solution, Bacillus subtilis solution, Trichoderma solution, etc., the type of microbial inoculant solution is selected according to the soil for forest seedling cultivation), the delivery pump 132 is fixedly installed on the right outer wall of the storage tank 131, one end of the suction pipe 133 is fixedly connected to the suction end of the delivery pump 132, the other end of the suction pipe 133 extends into the storage tank 131, one end of the discharge pipe 134 is fixedly connected to the discharge end of the delivery pump 132, one end of the hose 135 is fixedly connected to the other end of the discharge pipe 134, the hollow crossbeam 136 is fixedly installed on the front side wall of the lifting plate 3, the connecting pipe 137 is fixedly connected to the right end of the hollow crossbeam 136, the connecting pipe 137 is connected to the inside of the hollow crossbeam 136, and the hose 135... The other end is fixedly connected to the right end of connecting pipe 137. Solenoid valve 138 is fixedly installed on connecting pipe 137. Multiple diversion pipes 139 are fixedly connected to the rear side wall of hollow beam 136 and are evenly distributed. Multiple diversion pipes 139 are connected to the interior of hollow beam 136. The rear ends of multiple diversion pipes 139 are all closed structures. Multiple dripping vertical pipes 1310 are fixedly connected to the bottom of multiple diversion pipes 139 and are evenly distributed. The bottom ends of multiple dripping vertical pipes 1310 all penetrate horizontal plate 42 and are located inside U-shaped stainless steel frame 5. The suction fan 1311 is fixedly installed at the bottom of lifting plate 3 and located on the left side of hollow beam 136. One end of hose 1312 is fixedly connected to the air outlet of suction fan 1311. Connecting pipe 131 313 is fixedly connected to the left end of the hollow crossbeam 136. Connecting pipe 2 1313 is connected to the inside of the hollow crossbeam 136. The other end of flexible hose 2 1312 is fixedly connected to the left end of connecting pipe 2 1313. Solenoid valve 3 1314 is fixedly installed on connecting pipe 2 1313. By opening solenoid valve 3 1314 and controlling solenoid valve 2 138 to close, the suction fan 1311 is started, which can deliver air into the hollow crossbeam 136. The air entering the hollow crossbeam 136 is diverted by multiple diversion pipes 139 and finally discharged from multiple drip vertical pipes 1310 and blown downwards onto the soil, thus cooling the soil. By opening solenoid valve 2 138 and controlling solenoid valve 3 1314 to close, the delivery pump 132 is started.The microbial agent solution in the storage tank 131 can be pumped into the hollow beam 136. Inside the hollow beam 136, the microbial agent solution is diverted by multiple diversion pipes 139 and finally discharged from multiple drip vertical pipes 1310, falling from top to bottom into the soil. This allows for the application of the microbial agent solution to the soil. Furthermore, by applying the microbial agent solution to the heated and baked soil, the soil microbial community is replenished, enabling the formation of a dominant microbial community, inhibiting the recurrence of harmful organisms, and simultaneously restoring the soil ecosystem. (To improve soil fertility and promote seedling root development), providing a guarantee for subsequent forest seedling cultivation, the conveying pump 132, solenoid valve 138, solenoid valve 1314, and suction fan 1311 are electrically connected to the controller and battery pack 12. The battery pack 12 can supply power to the conveying pump 132, solenoid valve 138, solenoid valve 1314, and suction fan 1311. The control buttons on the controller can control the power supply and operation of the conveying pump 132, solenoid valve 138, solenoid valve 1314, and suction fan 1311.

[0055] In this embodiment, a liquid filling hole is provided on the top of the liquid storage tank 131, and a stopcock 1315 is installed in the internal thread of the liquid filling hole. The design of the liquid filling hole and the stopcock 1315 is to facilitate the addition of microbial agent solution into the liquid storage tank 131. A liquid level observation window 1316 is fixedly installed on the front side wall of the liquid storage tank 131. The design of the liquid level observation window 1316 is to facilitate the observation of the remaining amount of microbial agent solution in the liquid storage tank. A liquid flow meter 1317 is fixedly installed on the liquid outlet pipe 134. The design of the liquid flow meter 1317 is to facilitate the measurement of the volume of microbial agent solution flowing out of the liquid outlet pipe 134, so as to avoid excessive application of microbial agent solution to the soil.

[0056] In this embodiment, with the above structure, when the soil for the prevention and control of forestry soil pests and diseases provided in this application is heated and the insects are killed according to the steps of Embodiment 1, the suction fan 1311 is started and the solenoid valve 3 1314 and solenoid valve 1 419 are opened, and the solenoid valve 2 138 is controlled to be closed. The airflow generated by the suction fan 1311 enters the hollow crossbeam 136 through the hose 2 1312 and the connecting pipe 2 1313, and then is divided by multiple diversion pipes 139 and blown from top to bottom onto the soil through multiple drip vertical pipes 1310. With the continued operation of the motor 416, the soil is stirred and broken, which can achieve rapid and comprehensive cooling of the soil and avoid the continuous damage of the soil structure by high temperature. The heat in the soil can be discharged from the exhaust pipe 418 along with the airflow.

[0057] When the soil temperature is cooled to below 25-30℃, stop the operation of the suction fan 1311, close solenoid valve 3 1314 and solenoid valve 1 419, open solenoid valve 2 138 and start the delivery pump 132. The delivery pump 132 draws the microbial agent solution from the storage tank 131 through the suction pipe 133, and sends it into the hollow crossbeam 136 through the outlet pipe 134, hose 135, and connecting pipe 137. Then, through the diversion of multiple diversion pipes 139, the microbial agent solution is evenly dripped into the soil from multiple drip vertical pipes 1310. With the continued operation of the motor 416, the soil is stirred and broken up, which can fully mix the microbial agent solution with the soil. The liquid flow meter 1317 on the outlet pipe 134 can accurately measure the liquid flow. Dosage of microbial agent should be carefully controlled to avoid over-application. After the microbial agent solution enters the soil, it can quickly replenish beneficial bacteria, form a dominant community to inhibit the recurrence of harmful organisms, and at the same time restore the soil ecology and improve fertility. After the microbial agent solution is applied to the soil, stop the operation of the delivery pump 132 and close the solenoid valve 138. At this time, the suction fan 1311 can be restarted for 15-20 seconds, and the solenoid valves 1314 and 419 can be opened. The airflow generated by the suction fan 1311 can blow the residual microbial agent solution in the hollow crossbeam 136, multiple diversion pipes 139 and multiple drip vertical pipes 1310 into the soil. After the microbial agent solution is mixed with the soil, stop the operation of the motor 416.

[0058] Next, the hydraulic cylinder 2 is controlled to retract and reset. The output shaft of the hydraulic cylinder 2 drives the lifting plate 3 to move vertically upward back to its original position. The heating and insecticidal mechanism 4 and the U-shaped stainless steel frame 5 move upward to the ground simultaneously. The staff pushes the device forward a distance. Following the operation steps of Example 1 and Example 2, the pest and disease control treatment of the soil in the next area can continue.

[0059] Third Embodiment

[0060] Based on the control device for forestry soil pests and diseases provided in the first and second embodiments of this application, the third embodiment of this application proposes another control device for forestry soil pests and diseases. The third embodiment is merely a preferred embodiment of the first or second embodiment, and the implementation of the third embodiment will not affect the individual implementation of the first or second embodiment.

[0061] The third embodiment of this application will be further described below with reference to the accompanying drawings and embodiments.

[0062] See Figure 15 and Figure 16In a forestry soil pest and disease control device: a fixed beam 14 is fixedly installed on the right rear leg 7 of the four legs 7. An L-shaped hanging rod 15 is fixedly installed at the bottom of the fixed beam 14. A fixed plate 16 is fixedly fitted on the L-shaped hanging rod 15. A plastic film roll 17 and a movable plate 18 are slidably fitted on the L-shaped hanging rod 15. The rear end of the plastic film roll 17 is in contact with the fixed plate 16, and the front end of the plastic film roll 17 is in contact with the movable plate 18. An external thread is opened on the circumferential side of the front end of the L-shaped hanging rod 15. A locking nut 19 is installed on the front end of the L-shaped hanging rod 15 through the external thread. The locking nut 19 abuts against the front side wall of the movable plate 18. The L-shaped hanging rod 15 is used to support the plastic film roll 17. With the synergistic effect of the movable plate 18 and the fixed plate 16, the position of the plastic film roll 17 can be adjusted. To prevent the mulch film roll 17 from sliding and shifting on the L-shaped hanging rod 15, a locking nut 19 is used to connect with the external thread at the front end of the L-shaped hanging rod 15, facilitating the disassembly and replacement of the mulch film roll 17. After heating and baking the soil to kill pests and diseases and applying microbial inoculant solution, workers can manually cover the soil surface with film to retain moisture and promote the colonization of beneficial bacteria in the soil, laying the foundation for subsequent tree seedling cultivation. Tree seedling cultivation can begin after the soil has been kept moist for 2-3 days. The mulch film roll 17 is made of fully biodegradable mulch film made of materials such as PBAT and PLA, which also eliminates the need for manual cleaning and recycling of the mulch film later. The fully biodegradable mulch film can complete degradation within 30 to 60 days, which is in line with the development concept of green ecological forestry.

[0063] In this embodiment, with the above structure, when the microbial agent is applied according to the steps of Embodiment 2, the staff pulls out the fully biodegradable mulch film from the mulch film roll 17 on the L-shaped hanging pole 15 and manually covers it on the treated soil surface. This can moisturize and maintain the soil, promote the colonization of beneficial bacteria, and after the soil has been moisturized for 2-3 days, the seedlings can be planted. Furthermore, the fully biodegradable mulch film can degrade naturally within 30-60 days without the need for subsequent manual recycling.

[0064] The foregoing has provided a detailed description of a control device for forestry soil pests and diseases. Specific embodiments have been used to illustrate the principles and implementation methods of this application. These embodiments are merely illustrative and are intended to aid in understanding the method and core concepts of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
