Description

Technical Field

[0001] This invention relates to the field of kiwifruit root rot prevention and control technology, and in particular to a method for preventing and controlling kiwifruit root rot. Background Technology

[0002] Kiwi root rot is a devastating fungal disease that causes rot in the root collar and root cortex. Due to nutrient deficiency, fine roots fail to develop, resulting in a bare root system, and in severe cases, the entire plant dies. Control of kiwi root rot largely relies on chemical treatments, such as pyrethroid insecticides and fungicides like Mancozeb. In the early stages of the disease, mancozeb or Bordeaux mixture can be used for root drenching. For infected mature orchards, fungicides like Carbendazim or Thiophanate-methyl can be used for root drenching.

[0003] In the existing technology, when applying pesticides to the roots of kiwifruit, there is a lack of effective irrigation equipment, which prevents the pesticides from making uniform contact with the roots. Therefore, we propose a method for the prevention and control of kiwifruit root rot to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of effective root irrigation equipment when applying pesticides to the roots of kiwifruit, which prevents the pesticides from making uniform contact with the roots. Therefore, this invention proposes a method for the prevention and control of root rot in kiwifruit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A method for preventing and controlling root rot in kiwifruit includes the following steps:

[0007] S1. Prepare the root irrigation equipment, which includes a mounting base with a liquid chamber. A vertical plate is fixedly installed on the top of the mounting base, and a hollow plate is fixedly installed on one side of the vertical plate. Multiple first hoses are fixedly connected to the bottom of the hollow plate, and a sleeve is fixedly connected to one end of each of the multiple first hoses. A conical head is fixedly installed at the bottom of each of the multiple sleeves, and a vertical hole is opened on the conical head. Adjacent sleeves are rotatably connected by a rotating component. The mounting base is equipped with a liquid delivery mechanism for delivering liquid into the hollow plate. An anti-blocking mechanism is provided on the multiple sleeves, which cooperates with the vertical hole. An agitation mechanism is provided in the liquid chamber, and a liquid inlet for adding liquid is provided on the top of the mounting base.

[0008] S2. Add the agent into the liquid chamber through the liquid inlet. Since the multiple inserts are connected to each other by rotation, the inserts can be rotated to make them into a ring shape, which is then placed on the outside of the kiwi tree trunk. Then, insert the multiple inserts into the soil so that the multiple conical heads are inserted near the roots of the kiwi tree.

[0009] S3. Then, activate the anti-blocking mechanism to release the blockage of the vertical holes, activate the liquid delivery mechanism to extract the liquid from the liquid chamber, so that the liquid enters the hollow plate, and then enters multiple sleeves through multiple first hoses. Finally, the liquid is sprayed from multiple vertical holes onto the kiwi roots, so that the liquid is evenly in contact with the kiwi roots.

[0010] The liquid delivery mechanism includes a delivery pump fixedly installed on the top of the mounting base. The inlet of the delivery pump is fixedly connected to a suction pipe located inside the liquid chamber. The outlet of the delivery pump is fixedly connected to one end of a delivery pipe, the other end of which is fixedly connected to a hollow plate. When the delivery pump is turned on, the liquid in the liquid chamber is drawn through the suction pipe and delivered to the hollow plate via the delivery pipe. The anti-clogging mechanism includes multiple plug rods, each located within a multiple sleeve. The outer sides of the plug rods contact the inner walls of multiple vertical holes. Hollow columns are fixedly installed on the tops of the multiple sleeves. Circular openings are formed at the bottoms of the hollow columns and the tops of the multiple sleeves. The plug rod has a hole in which the outer side slides in contact with the inner wall of the circular hole. When the insert needs to be inserted into the soil, the plug rod seals the vertical hole on the conical head to prevent soil from entering. The top of the plug rod extends into the hollow column and is fixedly installed with a first piston. The outer side of the first piston slides in contact with the inner wall of the hollow column. One end of a spring is fixedly installed at the bottom of the first piston, and the other end of the spring is fixedly connected to the bottom inner wall of the hollow column. Multiple hollow columns are fixedly connected with second hoses. Hydraulic oil is contained in the second hoses and hollow columns. When hydraulic oil enters the second hoses and hollow columns, the hydraulic oil squeezes the first piston downward, and the first piston drives the plug rod downward to block the soil. The spring is compressed when the vertical hole is inserted. After insertion into the soil, the hydraulic oil inside the hollow column is removed, causing the spring to reset. This allows the first piston to move the plug rod upwards, releasing the blockage of the vertical hole. The mounting base has multiple extrusion chambers, each containing a second piston. One end of each of the multiple second hoses is fixedly connected to one of the extrusion chambers. The mounting base also has a movable cavity containing a movable plate. Multiple push-pull rods are fixedly mounted on one side of the movable plate, with one end extending into each extrusion chamber and fixedly connected to one end of each of the multiple second pistons. The movable plate then drives multiple... The push-pull rod moves horizontally, and multiple push-pull rods drive multiple second pistons to move, thereby pumping hydraulic oil. The stirring mechanism includes a stirring rod rotatably mounted on the inner wall of the top of the liquid chamber, with multiple stirring blades fixedly mounted on the outer side of the stirring rod, and a second bevel gear fixedly mounted on the outer side of the stirring rod. A transmission rod is rotatably mounted on one side of the inner wall of the liquid chamber, with a first bevel gear fixedly mounted at one end of the transmission rod. The first bevel gear meshes with the second bevel gear, and the transmission rod drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate. The second bevel gear drives the stirring rod to rotate, and the rotation of the stirring rod drives the stirring blades to rotate, thus stirring the medicine.A mounting groove is formed on one inner wall of the movable cavity, and a motor is fixedly installed in the mounting groove. A screw is fixedly installed on the output shaft of the motor, and the screw is threadedly connected to the movable plate. A drive gear is fixedly sleeved on the outer side of the screw, and a driven gear meshes with the drive gear. One end of the transmission rod extends into the movable cavity and is fixedly connected to the driven gear. The motor drives the screw to rotate, causing the movable plate threadedly connected to the screw to move horizontally. The screw drives the drive gear to rotate, which in turn drives the driven gear to rotate, and the driven gear drives the transmission rod to rotate. The rotating assembly includes multiple connecting blocks and multiple U-shaped blocks, which are respectively fixedly installed on the outer side of the corresponding inserts. Each connecting block has a rotating hole, and each U-shaped block has a rotating shaft fixedly installed. The outer side of the rotating shaft contacts the inner wall of the rotating hole.

[0011] The beneficial effects of the method for preventing and controlling root rot in kiwifruit described in this invention are as follows:

[0012] Add the medicine into the medicine chamber through the liquid inlet. Since the multiple inserts are connected to each other by rotation, the inserts can be rotated to make them into a ring shape, which is then placed on the outside of the kiwi tree trunk. Then, the multiple inserts are inserted into the soil so that the multiple conical heads are inserted near the roots of the kiwi tree.

[0013] Hydraulic oil is extracted from the hollow column through the second hose, relieving the pressure on the first piston. At this time, the spring is released from its contracted state, causing the plug rod to move upward, so that the bottom end of the plug rod enters the insert, relieving the blockage of the vertical hole on the conical head. The stirring rod rotates, driving the stirring blade to rotate, stirring the agent to make the agent more uniform. Then, the delivery pump is started, and the agent is extracted from the agent chamber through the liquid extraction pipe. The agent is delivered to the hollow plate through the liquid delivery pipe, and then enters multiple inserts through multiple first hoses. Finally, the agent is sprayed from multiple vertical holes onto the kiwi fruit roots, so that the agent is evenly contacted with the kiwi fruit roots.

[0014] This invention allows for uniform irrigation of the agent, ensuring even contact between the agent and the kiwifruit roots, thereby improving the control effect against kiwifruit root rot. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Example 1

[0024] Reference Figures 1-5 A method for preventing and controlling root rot in kiwifruit includes the following steps:

[0025] S1. Prepare the root irrigation equipment, which includes a mounting base 1. The mounting base 1 has a liquid chamber 3. A vertical plate 4 is fixedly installed on the top of the mounting base 1. A hollow plate 5 is fixedly installed on one side of the vertical plate 4. Multiple first hoses 6 are fixedly connected to the bottom of the hollow plate 5. A plug sleeve 7 is fixedly connected to one end of each of the multiple first hoses 6. A conical head 8 is fixedly installed at the bottom of each of the multiple plug sleeves 7. The multiple plug sleeves 7 are evenly spaced. A vertical hole is opened on the conical head 8. Adjacent plug sleeves 7 are rotatably connected by a rotating component. The mounting base 1 is provided with a liquid delivery mechanism for delivering liquid into the hollow plate 5. An anti-blocking mechanism is provided on each of the multiple plug sleeves 7. The anti-blocking mechanism cooperates with the vertical hole. An agitation mechanism is provided in the liquid chamber 3. A liquid inlet 40 for adding liquid is provided on the top of the mounting base 1.

[0026] The liquid delivery mechanism includes a delivery pump 9 fixedly installed on the top of the mounting base 1. The inlet of the delivery pump 9 is fixedly connected to a suction pipe 10, which is located inside the liquid chamber 3. The outlet of the delivery pump 9 is fixedly connected to one end of a delivery pipe 11, and the other end of the delivery pipe 11 is fixedly connected to a hollow plate 5. When the delivery pump 9 is turned on, the liquid in the liquid chamber 3 is drawn through the suction pipe 10, and the liquid is delivered to the hollow plate 5 through the delivery pipe 11. The anti-clogging mechanism includes multiple plug rods 16, which are located in multiple inserts 7. The outer sides of the multiple plug rods 16 are respectively connected to the inner walls of multiple vertical holes. The top of each of the multiple inserts 7 is fixedly equipped with a hollow column 17. The bottom of each hollow column 17 and the top of each insert 7 are provided with circular holes. The outer side of the plug rod 16 slides in contact with the inner wall of the circular hole. When the insert 7 needs to be inserted into the soil, the plug rod 16 seals the vertical hole on the conical head 8 to prevent soil from entering. The top of the plug rod 16 extends into the hollow column 17 and is fixedly equipped with a first piston 18. The outer side of the first piston 18 slides in contact with the inner wall of the hollow column 17. One end of a spring 19 is fixedly installed at the bottom of the first piston 18, and the other end of the spring 19 is connected to the bottom of the hollow column 17. The inner wall of the unit is fixedly connected, and multiple hollow columns 17 are each fixedly connected to a second hose 20. Hydraulic oil is contained within the second hose 20 and the hollow columns 17. When hydraulic oil enters the second hose 20 and the hollow columns 17, the hydraulic oil compresses the first piston 18, causing it to move downwards. The first piston 18 drives the blocking rod 16 downwards to block the vertical hole, compressing the spring 19. After insertion into the soil, the hydraulic oil in the hollow column 17 is withdrawn. At this time, the spring 19 returns to its original position, causing the first piston 18 to drive the blocking rod 16 upwards, releasing the blockage of the vertical hole. The mounting base 1 has multiple extrusion chambers 21 and 22... Each of the mounting bases has a second piston 22 slidably installed inside the mounting base. One end of each of the multiple second hoses 20 is fixedly connected to a multiple extrusion chamber 21. A movable chamber 2 is provided on the mounting base 1. A movable plate 24 is slidably installed inside the movable chamber 2. A multiple push-pull rods 23 are fixedly installed on one side of the movable plate 24. One end of each push-pull rod 23 extends into the multiple extrusion chambers 21, and one end of each push-pull rod 23 is fixedly connected to one end of each of the multiple second pistons 22. The movable plate 24 drives the multiple push-pull rods 23 to move horizontally, and the multiple push-pull rods 23 drive the multiple second pistons 22 to move, thereby realizing the pumping of hydraulic oil.The stirring mechanism includes a stirring rod 36 rotatably mounted on the inner wall of the top of the liquid chamber 3. Multiple stirring blades 39 are fixedly mounted on the outer side of the stirring rod 36. A second bevel gear 38 is fixedly mounted on the outer side of the stirring rod 36. A transmission rod 33 is rotatably mounted on one inner wall of the liquid chamber 3. A first bevel gear 37 is fixedly mounted at one end of the transmission rod 33. The first bevel gear 37 meshes with the second bevel gear 38. The transmission rod 33 drives the first bevel gear 37 to rotate, which in turn drives the second bevel gear 38 to rotate. The second bevel gear 38 then drives the stirring rod 36 to rotate, which in turn drives the stirring blades 39 to rotate, thus stirring the liquid and moving the chamber 2. An installation groove is provided on one side of the inner wall, and a motor 32 is fixedly installed in the installation groove. A screw 25 is fixedly installed on the output shaft of the motor 32. The screw 25 is threadedly connected to the moving plate 24. A drive gear 34 is fixedly sleeved on the outside of the screw 25. A driven gear 35 meshes on the drive gear 34. One end of the transmission rod 33 extends into the moving cavity 2 and is fixedly connected to the driven gear 35. The motor 32 drives the screw 25 to rotate, so that the moving plate 24 threadedly connected to the screw 25 moves horizontally. The screw 25 drives the drive gear 34 to rotate, the drive gear 34 drives the driven gear 35 to rotate, and the driven gear 35 drives the transmission rod 33 to rotate.

[0027] S2. When irrigating the roots, add the agent into the liquid chamber 3 through the liquid inlet 40. Since the multiple inserts 7 are connected to each other by rotation, the multiple inserts 7 can be rotated to make the multiple inserts 7 into a ring shape, which is then placed on the outside of the kiwi tree trunk. Then, the multiple inserts 7 are inserted into the soil so that the multiple conical heads 8 are inserted near the roots of the kiwi tree.

[0028] S3. Then, the motor 32 drives the screw 25 to rotate, causing the movable plate 24, which is threadedly connected to the screw 25, to move to the right. The movable plate 24 drives multiple push-pull rods 23 to move to the right, and the multiple push-pull rods 23 drive multiple second pistons 22 to move to the right. The hydraulic oil in the hollow column 17 is drawn out through the second hose 20, releasing the compression on the first piston 18. At this time, the spring 19 is released from its contracted state, causing the blocking rod 16 to move upward, so that the bottom end of the blocking rod 16 enters the insert 7, releasing the blockage on the vertical hole on the conical head 8. When the screw 25 rotates, it drives the drive gear 34 to rotate, and the drive gear 34 drives the driven gear. The driven gear 35 rotates, driving the transmission rod 33 to rotate, which in turn drives the first bevel gear 37 to rotate. The first bevel gear 37 drives the second bevel gear 38 to rotate, which in turn drives the stirring rod 36 to rotate. The rotation of the stirring rod 36 drives the stirring blade 39 to rotate, thus agitating the agent and making it more uniform. Then, the delivery pump 9 is started, and the liquid in the liquid chamber 3 is drawn through the liquid extraction pipe 10. The liquid is delivered to the hollow plate 5 through the liquid delivery pipe 11, and then enters the multiple inserts 7 through multiple first hoses 6. Finally, the agent is sprayed from multiple vertical holes onto the kiwi roots, so that the agent is evenly in contact with the kiwi roots.

[0029] Reference Figure 1 The rotating assembly includes multiple connecting blocks 12 and multiple U-shaped blocks 14. The multiple connecting blocks 12 and multiple U-shaped blocks 14 are respectively fixedly installed on the outer side of the corresponding plug sleeve 7. Each of the multiple connecting blocks 12 has a rotating hole 13. Each of the multiple U-shaped blocks 14 has a rotating shaft 15 fixedly installed on it. The outer side of the rotating shaft 15 is in contact with the inner wall of the rotating hole 13.

[0030] Specifically, such as Figure 1 As shown, except for the leftmost socket 7 which does not have a connecting block 12 installed, all other sockets 7 have a connecting block 12 installed. Except for the rightmost socket 7 which does not have a U-shaped block 14 installed, all other sockets 7 have a U-shaped block 14 installed.

The first conductive block 29, the power supply 30, the indicator light 31 and the second conductive block 28 are connected in sequence by wires. When the first piston 18 moves upward, it will drive the insulating rod 26 to move upward. The insulating rod 26 drives the first conductive block 29 to contact the second conductive block 28. At this time, the circuit composed of the first conductive block 29, the power supply 30, the indicator light 31 and the second conductive block 28 is connected, and the indicator light 31 lights up, indicating that the blockage of the vertical hole has been released and the root dredging work can be carried out. The indicator light 31 serves as a prompt.
