Description

TECHNICAL FIELD

[0001] The present application belongs to the field of root disease treatment. More particularly, the present application relates to a device for preventing and treating root diseases and pests of fruit trees. BACKGROUND

[0002] During the growth of fruit tree seedlings, if the roots of the seedlings are infected with root-knot nematodes, the root system of the fruit tree seedlings will develop abnormally, a large number of tender roots will die after transplanting, and finally the survival rate of the fruit tree seedlings after transplanting will be low. Tree root diseases and pests are destructive, secretive and difficult to control. Therefore, it is of great significance to prevent and treat the root diseases and pests of fruit tree seedlings to avoid the planting of diseased seedlings and to facilitate the growth and management of fruit trees in the later stage. Patent No. CN206963501U discloses a device for killing pests in kiwi seedling roots. First, the kiwi seedlings are placed in the installation pipe, fixed by the installation pipe, and the roots of the seedlings are immersed in the copper sulfate solution. The copper sulfate solution is used to kill pests in the roots of the seedlings. The iron powder layer inside the installation pipe contacts the copper sulfate solution to produce hydrogen gas. The hydrogen gas forms bubbles in the copper sulfate solution, which impact the roots of the seedlings, causing the entangled root hairs to expand and killing the hidden root-knot nematodes. The bubbles hitting the installation pipe will cause the installation pipe and the through hole to rotate, so that the soil around the roots of the seedlings is washed away, and the root-knot nematodes are more easily removed. The technology relies on the bubbles generated by hydrogen gas to impact the roots to achieve the washing of the soil around the roots, which is relatively inefficient. SUMMARY

[0104] .

[0105] Table 1 The results of the seedling control effect

[0106]

[0107] From the results of Table 1, the results of Comparative Example 1 and Example 2 show that the electric shock killing can better kill the root nematodes and has a good control effect on the root nematodes, and the simple oscillation cleaning is not ideal for the control effect on the root nematodes. The results of Comparative Example 2 and Example 2 show that the setting of the second plate body 4 and the vibration structure helps to increase the turbulence of the water flow, increase the cleanliness of the root part, and thus helps to kill the root nematodes and improve the control 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 root part, and thus helps to kill the root nematodes and improve the control effect. The results of Comparative Example 4 and Example 2 show that the electric shock killing during the rotation of the water body can improve the control effect to a certain extent, and the possible reason is that the rotation and vibration can change the position of the worm body or worm egg, so that it is more easily killed by the electric shock. The results of Example 2 and Comparative Example 5 show that the low-voltage pretreatment before the high-voltage electric shock killing can create an unsuitable environment for the root nematodes, so that they crawl out of the root part, and thus enhance the effect of the high-voltage electric shock killing.
