Description

Technical Field

[0001] The present invention relates to the technical field of plant protection, and in particular to a method for preventing and controlling plant diseases and insect pests in natural forests. Background Art

[0002] To protect the forest ecosystem and mitigate the damage to forestry crops caused by pathogenic microorganisms or pests, chemical control measures such as pesticides are often implemented. For example, Chinese patent CN113841678B discloses a pesticide spraying device and method for forestry pest control, which relates to the field of pesticide spraying. The device comprises an adsorption assembly and a pipe fitting. The adsorption assembly is a conical, expandable housing, which is vertically distributed between the adsorption assembly and the pipe fitting. The pipe fitting includes a nozzle located at the core of the adsorption assembly and a suction and discharge pipe fitting connected to the nozzle for conveying the pesticide. The suction and discharge pipe fitting is equipped with an expansion and contraction control assembly. The expansion and contraction control assembly moves closer to or further away from the adsorption assembly with the suction and discharge pipe fitting as the axis. The suction and discharge pipe fitting applies adsorption force to the adsorption assembly, and the conical, expandable housing serves as a filter medium to adsorb the atomized pesticide dispersed into the air.

[0003] In the current process of forest disease and insect pest control, chemical pesticides are usually simply sprayed. In order to improve the effect of killing pests and diseases, the amount of chemical pesticide spraying is only increased, and the performance of insecticides is not fully utilized. Moreover, the large-scale use of insecticides cannot adapt to the large-scale forest disease and insect pest control field such as natural forest farms. It is not only easy for pests and diseases to develop drug resistance, but also easy to cause the deterioration of the forest ecological environment. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for preventing and controlling pests and diseases in natural forests, using insecticides based on high-efficiency thermal fog control technology, effectively controlling the amount of insecticides used, and making atomizing equipment suitable for natural forests to improve prevention and control efficiency.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: a method for preventing and controlling plant diseases and insect pests in natural forests, comprising the following steps:

[0006] S1. Prepare an insecticide adjuvant, which comprises the following components in percentage by weight: 1.0-5.0% high molecular weight hyaluronic acid, 0.2-1.5% low molecular weight hyaluronic acid, 2-6% surfactant, 3-12% condensation nucleus material, 2-8% water-soluble vitamin E, 3-15% emulsifier, and the balance water;

[0007] S2. Dilute the insecticide adjuvant with deionized water in the storage tank of the atomizer;

[0008] S3, adding the insecticide to the medicine storage barrel, stirring and mixing evenly to obtain a control liquid, the control liquid comprising the following components in percentage by weight: 2-16% of the insecticide, 1-3% of the insecticide adjuvant, and the balance being deionized water;

[0009] S4. Connect the liquid distribution assemblies at both ends of the rotating rod of the atomizing device to the trunk of the tree, respectively. The medicine storage barrel supplies pest control liquid to the temporary liquid storage container of the liquid distribution assembly at one end of the rotating rod through the first liquid supply pipeline. The temporary liquid storage container of the liquid distribution assembly at the other end of the rotating rod is empty. The liquid distribution assembly with the temporary liquid storage container filled with pest control liquid moves downward along the trunk of the tree under the action of gravity. The rotating rod changes from a horizontal state to an inclined state. The liquid distribution assembly with the other temporary liquid storage container empty is driven by the rotating rod and moves upward along the trunk of the tree.

[0010] S5. The atomizing and heating device of the liquid distribution assembly, which is filled with pesticide liquid inside the liquid distribution temporary storage container, operates. The atomizing and heating device heats the pesticide liquid into atomized form and then sprays it out through the rotating nozzle at the end of the vertical pipe. At the same time, the pesticide storage barrel supplies the pesticide liquid to the liquid distribution assembly's temporary storage container located high in the tree trunk. As the weight of the liquid distribution assembly located low in the tree trunk decreases and the weight of the liquid distribution assembly located high in the tree trunk increases, the liquid distribution assembly located low in the tree trunk moves upward from bottom to top, while the liquid distribution assembly located high in the tree trunk moves downward from top to bottom.

[0011] The above-mentioned prevention and control method is implemented based on an atomizing medicine device, which includes a mobile base, a support, a rotating rod and a liquid distribution assembly. A medicine storage barrel is provided on the mobile base, and the support is fixedly installed on the mobile base. The middle part of the rotating rod is rotatably installed on the end of the support, and symmetrically arranged liquid distribution assemblies are provided at both ends of the rotating rod. The liquid distribution assembly includes an arc-shaped support seat, a medicine temporary storage container and an atomizing heating device. The trunk of the tree is stuck in the notch on the arc-shaped support seat, and the arc-shaped support seat is rotatably installed at the end of the rotating rod. A vertical pipe is provided on the arc-shaped support seat, and a rotatable rotating nozzle is provided at the end of the vertical pipe. The medicine temporary storage container is fixedly installed under the arc-shaped support seat. The medicine temporary storage container is connected to the medicine storage barrel through a first liquid supply pipeline, and a water pump is provided on the first liquid supply pipeline. The atomizing heating device is connected to the medicine temporary storage container through a second liquid supply pipeline. The output end of the atomizing heating device is connected to the liquid outlet pipe, and the vertical pipe is connected to the liquid outlet pipe.

[0012] As a further description of the above technical solution:

[0013] The insecticide adjuvant comprises the following components in percentage by mass: 2.0-4.0% of high molecular weight hyaluronic acid, 0.4-1.2% of low molecular weight hyaluronic acid, 2-5% of surfactant, 5-9% of condensation nucleus material, 2-4% of water-soluble vitamin E, 6-12% of emulsifier, and the balance is water.

[0014] As a further description of the above technical solution:

[0015] The particle size of the condensation nuclei is 2-5 μm.

[0016] As a further description of the above technical solution:

[0017] The supporting member is an electric push rod, and the middle part of the rotating rod is rotatably installed on the piston rod end of the supporting member.

[0018] As a further description of the above technical solution:

[0019] The rotating rod comprises an intermediate seat and a connecting arm, wherein the connecting arm is detachably mounted on the intermediate seat, and the intermediate seat is rotatably mounted on the supporting member.

[0020] As a further description of the above technical solution:

[0021] The connecting arm includes a main rod body and an inner rod body. The main rod body is detachably mounted on the middle seat. The inner rod body is elastically connected to the end of the main rod body. The arc-shaped support seat is rotatably mounted on the end of the inner rod body.

[0022] As a further description of the above technical solution:

[0023] A sphere is arranged on the inner wall of the arc-shaped support seat, the surface of the sphere contacts the tree trunk, and the sphere is rotatably mounted on the support rod, which is threadedly connected to the arc-shaped support seat.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In the present invention, a control liquid is heated and atomized by an atomizing device, forming fine droplets that are suspended in the air. These droplets diffuse into the branches and leaves of trees, killing and fumigating pests, controlling diseases and insect pests, improving the effective utilization rate of the insecticide, and effectively controlling the amount of insecticide used. The atomizing device does not require a drive device to control the vertical movement of the liquid distribution component, reducing energy consumption during spraying. This allows the atomizing device to perform long-term atomizing spraying in natural forests, making it suitable for natural forests and improving control efficiency.

[0026] 2. In the present invention, the atomizing device adjusts the weight of the liquid distribution components at both ends of the rotating rod, specifically by supplying the control liquid to the liquid storage container of the liquid distribution component. By changing the weight of the liquid distribution components at both ends of the rotating rod, the lifting and lowering movement of the liquid distribution components at both ends of the rotating rod is achieved. As the liquid distribution component located at the lower part of the tree trunk moves from bottom to top, it gradually completes the spraying of the liquid, the liquid storage container gradually becomes empty, the weight of the liquid distribution component gradually decreases, and it moves to the top, the liquid spraying is completed, and the liquid storage container is emptied; as the liquid distribution component located at the higher part of the tree trunk moves from top to bottom, the control liquid gradually fills the liquid storage container, the weight of the liquid distribution component gradually increases, and it moves to the bottom, the liquid storage container is full and ready for spraying. On the one hand, the liquid spraying effect of the liquid distribution component is improved, and the storage barrel continuously supplies liquid, thereby improving efficiency. On the other hand, there is no need to set up a separate drive device to control the lifting and lowering of the liquid distribution component, which reduces the energy consumption of the atomizing device during spraying.

[0027] 3. In the present invention, the control liquid consists of an insecticide and an insecticide adjuvant diluted with water. The insecticide adjuvant includes a surfactant, a condensation nucleus substance, a high-molecular-weight hyaluronic acid, a low-molecular-weight hyaluronic acid, and other substances. The high-molecular-weight hyaluronic acid can help absorb water and improve the anti-evaporation ability of the atomized liquid. The low-molecular-weight hyaluronic acid and water-soluble vitamin E cooperate with each other to prevent the insecticide from being absorbed by plant leaves, thereby improving the insecticidal effect.

[0040] Example 1

[0041] See also Figure 1-4The present invention provides a technical solution: a method for preventing and controlling pests and diseases in natural forests, comprising the following steps:

[0042] S1. Prepare an insecticide adjuvant, which comprises the following components in percentage by weight: 1.0-5.0% high molecular weight hyaluronic acid, 0.2-1.5% low molecular weight hyaluronic acid, 2-6% surfactant, 3-12% condensation nucleus material, 2-8% water-soluble vitamin E, 3-15% emulsifier, and the balance water;

[0043] S2. Dilute the insecticide adjuvant with deionized water in the medicine storage barrel 11 of the atomizing medicine device;

[0044] S3, adding the insecticide to the medicine storage barrel 11, stirring and mixing uniformly to obtain a control liquid, the control liquid comprising the following components in mass percentage: 2-16% of the insecticide, 1-3% of the insecticide adjuvant, and the balance being deionized water;

[0045] S4. Connect the liquid dispensing assemblies 4 at both ends of the rotating rod 3 of the atomizing medicine device to the trunk of the tree respectively. The medicine storage barrel 11 supplies the control liquid to the liquid dispensing assembly 4 at one end of the rotating rod 3 through the first liquid supply pipeline 421. The liquid dispensing assembly 4 at the other end of the rotating rod 3 has its liquid storage container 42 empty. The liquid dispensing assembly 4 filled with control liquid in the liquid storage container 42 moves downward along the trunk of the tree under the action of gravity. The rotating rod 3 changes from a horizontal state to an inclined state. The liquid dispensing assembly 4 with the empty liquid storage container 42 is driven by the rotating rod 3 and moves upward along the trunk of the tree.

[0046] S5. The atomizing and heating device 43 of the liquid dispensing assembly 4, which is filled with the control liquid in the liquid temporary storage container 42, starts to work. The atomizing and heating device 43 heats the control liquid into atomized form and then sprays it out through the rotating nozzle 412 at the end of the vertical pipe 411. At the same time, the medicine storage barrel 11 supplies the control liquid to the liquid temporary storage container 42 of the liquid dispensing assembly 4 located high in the tree trunk. As the weight of the liquid dispensing assembly 4 located low in the tree trunk decreases and the weight of the liquid dispensing assembly 4 located high in the tree trunk increases, the liquid dispensing assembly 4 located low in the tree trunk moves from bottom to top, while the liquid dispensing assembly 4 located high in the tree trunk moves from top to bottom.

[0047] The above prevention and treatment method is realized based on an atomizing drug device, which includes a mobile base 1, a support 2, a rotating rod 3 and a liquid distribution component 4. A drug storage barrel 11 is provided on the mobile base 1.

[0048] The support member 2 is fixedly mounted on the mobile base 1, the middle part of the rotating rod 3 is rotatably mounted on the end of the support member 2, and symmetrically arranged liquid distribution components 4 are provided at both ends of the rotating rod 3. The liquid distribution components 4 include an arc-shaped support seat 41, a temporary storage container for liquid medicine 42 and an atomizing heating device 43. The trunk of the tree is inserted into the notch on the arc-shaped support seat 41. The arc-shaped support seat 41 is rotatably mounted on the end of the rotating rod 3. A vertical pipe 411 is provided on the arc-shaped support seat 41, and a rotatable rotating nozzle 412 is provided at the end of the vertical pipe 411. An upwardly inclined spray hole can be provided on the rotating nozzle 412 to ensure that the sprayed control liquid can effectively contact the leaves of the trees. The liquid storage container 42 is fixedly installed under the arc-shaped support seat 41. The liquid storage container 42 is connected to the medicine storage barrel 11 through the first liquid supply pipeline 421. A water pump is provided on the first liquid supply pipeline 421. The atomizing heating equipment 43 is connected to the liquid storage container 42 through the second liquid supply pipeline. The output end of the atomizing heating equipment 43 is connected to the liquid outlet pipe 431, and the vertical pipe 411 is connected to the liquid outlet pipe 431.

[0049] Preferably, the insecticide adjuvant comprises the following components by weight: 2.0-4.0% high molecular weight hyaluronic acid, 0.4-1.2% low molecular weight hyaluronic acid, 2-5% surfactant, 5-9% condensation nucleus material, 2-4% water-soluble vitamin E, 6-12% emulsifier, and the balance water. Specifically, the surfactant can be a perfluorocarboxylate or a perfluorosulfonate. Specifically, the emulsifier can be one of fatty alcohol polyoxyethylene ether, fatty acid polyoxyethylene ether, and fatty amine polyoxyethylene ether.

[0050] The control liquid consists of an insecticide diluted with water and an insecticide adjuvant. The adjuvant includes surfactants, nucleation agents, high-molecular-weight hyaluronic acid, and low-molecular-weight hyaluronic acid. High-molecular-weight hyaluronic acid has a molecular weight of 600-1000 kDa, while low-molecular-weight hyaluronic acid has a molecular weight of 8-20 kDa. High-molecular-weight hyaluronic acid helps absorb water and improve the atomized liquid's resistance to evaporation. Low-molecular-weight hyaluronic acid and water-soluble vitamin E work together to prevent the insecticide from being absorbed by plant leaves, enhancing its effectiveness.

[0051] The particle size of the condensation nucleus material is 2-5 μm. This material is used to adjust the droplet size produced by the liquid distribution assembly 4. Specifically, it can be made from materials such as diatomaceous earth, white carbon black, and calcium carbonate. Any of these materials can be used singly or in combination. The diffusion effect of the atomized droplets and the pest control effects of different particle sizes of the condensation nucleus material in the insecticide adjuvant are observed and analyzed, and the particle size is optimized to achieve the best pest control results.

[0052] The support member 2 is an electric push rod, and the middle part of the rotating rod 3 is rotatably mounted on the end of the piston rod of the support member 2. According to the different lengths of the rotating rod 3, the height of the rotating rod 3 can be flexibly adjusted by extending and retracting the piston rod in the electric push rod, thereby achieving the adjustment of the liquid distribution assembly 4 to the lowest height of the tree trunk.

[0053] The rotating rod 3 includes an intermediate base 31 and a connecting arm 32. The connecting arm 32 is detachably mounted on the intermediate base 31, and the intermediate base 31 is rotatably mounted on the support 2. The connecting arm 32 can be detachably replaced by a threaded connection or other means to flexibly adjust the length of the rotating rod 3 to meet the spraying requirements of different tree spacings.

[0054] The connecting arm 32 includes a main rod 321 and an inner rod 322. The main rod 321 is detachably mounted on the intermediate base 31. The inner rod 322 is elastically connected to the end of the main rod 321. The arc-shaped support base 41 is rotatably mounted on the end of the inner rod 322. As the rotating rod 3 rotates, the inner rod 322 is compressed or stretched, compensating for changes in the distance between the arc-shaped support base 41 and the center of rotation of the rotating rod 3 during its vertical movement, thereby ensuring the stable position of the mobile base 1.

[0055] A sphere 413 is disposed on the inner wall of the arcuate support seat 41. The surface of the sphere 413 contacts the trunk of a tree. The sphere 413 is rotatably mounted on a support rod 414, which is threadedly connected to the arcuate support seat 41. The support rod 414 is rotated to adjust the distance between the sphere 413 and the center of the arcuate support seat 41 (or, in other words, to adjust the distance between the sphere 413 and the inner wall of the arcuate support seat 41). This allows the surface of the sphere 413 to contact the trunk of a tree when it is inserted into the notch of the arcuate support seat 41, thereby allowing the arcuate support seat 41 to move up and down smoothly.

[0056] Universal wheels 12 are provided at the bottom of the mobile base 1 for easy movement.

[0057] Working Principle: The atomizer heats and atomizes the pesticide solution, forming fine droplets suspended in the air. These droplets diffuse into the branches and foliage of trees, contact-killing and fumigating them, preventing and controlling pests and diseases, improving the effective utilization rate of the pesticide, and effectively controlling the amount of pesticide used. The atomizer eliminates the need for a drive to control the vertical movement of the liquid distribution assembly 4, reducing energy consumption during spraying. This allows for long-term atomization and spraying within natural forests, making it suitable for use in natural forests and improving control efficiency.

[0058] The atomizing device adjusts the weight of the liquid distribution assemblies 4 at both ends of the rotating rod 3 by adjusting the weight of the liquid distribution assemblies 4, specifically by supplying the pesticide liquid to the temporary storage container 42 of the liquid distribution assembly 4. This allows the assemblies 4 at both ends of the rotating rod 3 to move upward. As the liquid distribution assembly 4 at the lower end of the tree trunk moves upward, it gradually completes the spraying of the pesticide liquid. The temporary storage container 42 gradually becomes empty, and the weight of the liquid distribution assembly 4 gradually decreases. As the liquid distribution assembly 4 at the higher end of the tree trunk moves downward, the temporary storage container 42 gradually fills with pesticide liquid. The weight of the liquid distribution assembly 4 gradually increases, and as the assembly moves to the bottom, the temporary storage container 42 is filled and ready for spraying. This improves the spraying efficiency of the liquid distribution assembly 4, ensuring a continuous supply of pesticide liquid from the storage barrel 11, thereby increasing efficiency. Furthermore, it eliminates the need for a separate drive device to control the raising and lowering of the liquid distribution assembly 4, reducing energy consumption during spraying.

[0059] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
