Description

Technical Field

[0001] The present invention belongs to the field of root disease treatment, and more specifically, relates to a device for preventing and controlling root diseases and insect pests of fruit trees. Background Art

[0002] In the process of fruit trees growing into seedlings, if root-knot nematodes breed in the roots of the seedlings, the root system of the fruit tree seedlings will be poorly developed, and a large number of tender roots will die after transplanting, which will eventually lead to a low survival rate of transplanted fruit tree seedlings. Tree root diseases and insect pests are highly destructive, hidden, and difficult to control. Therefore, it is of great significance to control the roots of fruit tree seedlings and avoid planting diseased seedlings for the later growth and management of fruit trees. Patent publication number CN206963501U discloses a kiwi seedling root insecticide device. First, the kiwi seedling is placed in a mounting tube, fixed by the mounting tube, and the root of the seedling is immersed in a copper sulfate solution, and the copper sulfate solution is used to kill the seedling root; the iron powder layer inside the mounting tube contacts the copper sulfate solution to produce hydrogen, and the hydrogen forms bubbles in the copper sulfate solution, which impact the seedling root, so that the entangled roots unfold and the hidden root-knot nematodes are killed; and the bubbles hit the mounting tube, which causes the mounting tube and the through hole to rotate, so that the soil at the root of the seedling is washed away, and the root-knot nematodes are easier to fall out. This technology relies on the bubbles generated by hydrogen to impact the roots to achieve the flushing of the soil at the roots, and the efficiency is relatively low. Summary of the invention

[0043] The electric shock component includes a power supply and an electric shock plate 10 . The electric shock plate 10 is arranged at the bottom of the box body 1 . One end of the power supply is connected to the first plate body 2 , and the other end of the power supply is connected to the electric shock plate 10 .

[0044] In the technical scheme, the box body 1 is an open structure. The first plate body 2 is made of conductive material. A through hole is provided in the middle of the first plate body 2, and the rotating shaft 8 passes through the through hole. The rotating shaft 8 is fixedly connected to the through hole to drive the rotation of the first plate body 2 through the rotation of the rotating shaft 8. The rotating shaft 8 is made of non-conductive material, or its outer layer is wrapped with an insulating layer to make it insulating, so as to avoid the influence on the motor when the first plate body is energized. The first elastic member 5 is arranged on the edge of the second plate body 4, and is connected to the lower surface of the first plate body 2 so that the second plate body 4 can rotate relative to the first plate body 2. The first elastic member 5 is annular to seal the first gap between the first plate body and the second plate body; the diameter of the elastic ball 6 is greater than or equal to the width of the first gap. When the second plate body 4 is squeezed and moves upward, the elastic ball 6 is squeezed and has elastic force, which can drive the second plate body 4 to reset under the action of the elastic force. The seedling of the fruit tree is fixed in the first through hole 3, and the root penetrates into the box body 1 through the second through hole 11. The motor 7 and the rotating shaft 8 can be connected through a reducer, and the rotation of the rotating shaft 8 drives the stirring blade 9 to rotate, so as to use the water flow to clean the roots, avoid being wrapped by soil and reduce the killing effect of pests and diseases such as root nematodes. There is a second gap between the stirring blade 9 and the bottom of the box 1, and the electric shock plate 10 is arranged below the stirring blade 9. In some technical schemes, the thickness of the first plate body 2 and the second plate body 4 is 0.5-3cm, and the gap between the first plate body 2 and the second plate body 4 is 10-20cm. The voltage of electric shock is 1000V, the number of electric shocks is 1-3 times, and the electric shock time is 5-10s.

The second plate 4 can move relative to the first plate 2, so that the water flow under the second plate 4 becomes turbulent to enhance the cleaning ability of the roots, and the power of the electric shock plate 10 is turned on to complete the electric shock killing of fruit root pests and diseases.

[0046] In another technical solution, the bottom of the box body 1 is a conical structure, and a drainage hole 12 is provided at the bottom of the box body 1. The conical box body 1 is used to collect and discharge sludge and other debris generated by cleaning.

The first groove and the second groove are used to limit the elastic ball 6, so as to avoid the long-term relative movement of the first plate body 2 and the second plate body 4, which causes the elastic ball 6 to aggregate or distribute unevenly.

[0048] In another technical solution, a second elastic member 5 is provided above the second through hole 11, and the second elastic member 5 is fixedly connected to the lower surface of the first plate body 2. The second elastic member 5 is a cylindrical structure, with the lower end connected to the second plate body and the upper end connected to the first plate body. The second elastic member 5 is used to close the first gap between the upper part of the second through hole 11 and the first plate body 2 to prevent debris from entering the first gap and causing the second plate body 4 to be unable to move up and down relative to the first plate body 2.

[0049] In another technical solution, a vibration structure is also included, and the vibration structure includes:

[0053] In another technical solution, an annular groove is provided on the inner side wall of the upper end of the box body 1, and the first plate body 2 can be slidably nested in the annular groove. The annular groove has a limiting effect on the first plate body 2, preventing the first plate body 2 from moving upward with the second plate body 4 under the action of the vibration structure.

The mounting member 18 is provided with a mounting groove, and the upper end of the graphite block 17 can be slid up and down in the mounting groove;

[0057] The tension spring 19 has one end fixedly connected to the upper end of the graphite block 17 and the other end connected to the top of the mounting groove.

[0058] The technical solution utilizes the tension spring 19 to force the graphite block 17 to be closely attached to the first plate body 2 , so as to utilize the graphite block 17 to guide the power to the first plate body 2 .

[0059] In another technical solution, a fixing tube is provided in the first through hole 3, and the lower end of the fixing tube extends downward to the second through hole 11. The fixing tube is used to fix the roots of the seedlings, thereby protecting the roots of the seedlings and preventing the seedlings from being pinched when the second plate body 4 rotates relative to the first plate body 2.

[0060] In another technical solution, the stirring blade 9 is a conical cylindrical structure, a second gap is provided between the bottom of the stirring blade 9 and the bottom of the box 1, and a water retaining plate 15 is provided on the upper surface of the stirring blade 9.

In some technical solutions, an annular filter plate 16 is provided at the bottom of the box 1, and the annular filter plate is provided on the outside of the stirring blade. The free end of the annular filter plate 16 is higher than the free end of the stirring blade 9, and a third gap is provided between the free end of the stirring blade 9 and the annular filter plate 16. The annular filter plate 16 is used to filter the water body so that particles such as soil enter the bottom of the box 1 through the second gap, and the water body moves upward through the annular filter plate 16, thereby reducing impurities in the water body.

[0061] In another technical solution, a cleaning brush is provided on the lower surface of the stirring blade 9, and the lower surface of the cleaning brush abuts against the electric shock plate 10. The cleaning brush is a wire brush, and the stirring blade 9 is also made of a conductive material.

[0092] Comparative Example 2: The method of Example 2 is adopted, except that the prevention and control device does not include the second plate body 4 and the vibration structure, that is, there is water below the first plate body 2.

[0093] Comparative Example 3: The method of Example 2 is adopted, except that the prevention and control device does not include a vibration structure.

[0095] Comparative Example 5: The seedlings were planted directly without any treatment on their roots.

[0096] The seedlings treated as above were planted in soil disinfected with root nematodes and cultivated in a suitable environment for 45 days. The soil attached to the roots of the seedlings was washed away, the disease conditions of the plants with different treatments were investigated, the disease index was counted and the prevention effect was calculated.

[0097] Classification standards and prevention efficiency calculation method:

[0098] Grade 0: normal roots, no visible root knots;

[0099] Level 1: There are only a few root knots on the root system, accounting for 1-25% of the whole root system;

[0100] Level 2: The number of root nodes is moderate, accounting for 26-50% of the total root system;

[0107] From the results in Table 1, it can be seen that the results of Comparative Example 1 and Example 2 show that electric shock can kill root nematodes well and has a good preventive effect on root nematodes. Simple oscillation cleaning is not ideal for the prevention and control of root nematodes. The results of Comparative Example 2 and Example 2 show that the setting of the second plate 4 and the vibration structure helps to increase the turbulence of the water flow, increase the cleanliness of the roots, and then help to kill the root nematodes and improve the preventive effect. The results of Comparative Example 3 and Example 2 show that the vibration structure helps to increase the turbulence of the water flow, increase the cleanliness of the roots, and then help to kill the root nematodes and improve the preventive effect. The results of Comparative Example 4 and Example 2 show that electric shock during the rotation of the water body can improve the preventive effect to a certain extent. The possible reason is that rotation and vibration can change the position of the insect body or eggs, making it easier to be killed by electric shock.

For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
