Description

Technical Field

[0001] The utility model relates to the technical field of fruit tree cultivation, in particular to a rodent-proof device for cold-region Actinidia arguta kiwifruit. Background Art

[0002] Actinidia arguta is a large perennial deciduous vine plant of the genus Actinidia in the family Actiniaceae. It is widely distributed in the northern part of the world, mainly in China, the Russian Far East, Japan, South Korea, North Korea and other regions. It is distributed from Northeast China to the Qinling Mountains, and the resources of Actinidia arguta in Northeast China are the most abundant. Currently, China, the United States, Canada, New Zealand, Japan, South Korea and other countries have carried out large-scale commercial cultivation, and its output ranks first among small berries in the world.

[0003] The cultivation of soft-fleshed kiwifruit in cold regions is extremely susceptible to rodent damage. There are a large number of small rodents distributed in the Northeast, such as Daurian ground squirrels, voles, and house mice. After the winter, these animals turn to the phloem tissue in the rhizome area of ​​​​the soft-fleshed kiwifruit due to lack of food. In addition, since the rhizome needs snow to maintain the winter temperature, many rodents choose to build nests directly in the rhizome for easy feeding and wintering, which further aggravates the occurrence of rodent damage. Soft-fleshed kiwifruit mainly relies on phloem to transport nutrients and water. Since the root system of soft-fleshed kiwifruit has high water content and high root pressure, in the initial growth period of the plant in spring, due to pruning or injury, the wounded part of the soft-fleshed kiwifruit can overflow water and nutrients. This phenomenon is the phenomenon of wound flow. Rodent damage will aggravate the symptoms of wound flow, resulting in serious loss of nutrients and water in the tree, reducing the tree's resistance to stress, unable to overwinter or infected with kiwifruit canker bacteria. The aboveground part of the affected tree often dies in May of the following year, causing devastating consequences.

[0004] At present, the prevention and control of rodent pests mainly rely on chemical bait poisoning and manual capture, among which poison bait luring and killing easily kills the natural enemies of rodents such as weasels and yellow weasels by mistake, and also easily pollutes the environment and causes harm to the human body. Manual capture is labor-intensive and time-consuming, and the capture speed is far less than the reproduction speed of rodents. In order to prevent rodent harm and reduce costs. In view of the lack of economical and affordable rodent-proof devices on the market, the present invention aims to design an economical and affordable device that is easy to operate and can meet the needs of a large number of rodent pests in jujube orchards. Utility Model Content

[0005] The utility model aims to provide a cold-region kiwifruit rodent-proof device, which solves the problems of causing the death of natural enemies and being time-consuming and labor-intensive in the existing rodent-proofing methods.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] The utility model provides a rodent-proof device for cold-region soft-fruited kiwifruit, comprising two first cylindrical parts and a second cylindrical part that are spliced ​​together;

[0008] Wherein, the top outer peripheral walls of the first cylindrical body and the second cylindrical body are respectively provided with multiple layers of rat-proof spikes;

[0009] The outer circumferential walls of the first cylindrical body and the second cylindrical body are evenly provided with air holes;

[0010] A plurality of ground-inserting piles inserted into the soil are respectively arranged at the lower end of the first cylindrical body and the lower end of the second cylindrical body along the axial direction thereof;

[0011] Wherein, reserved plug-in grooves are respectively arranged at both radial ends of the first cylindrical body, and limiting plug-in ribs adapted to be plugged in with the reserved plug-in grooves are respectively arranged at both radial ends of the second cylindrical body.

[0012] Furthermore, the first cylindrical body and the second cylindrical body are respectively semicircular arc plates of equal diameter, which are convenient for insertion into the soil layer at the root of the fruit tree.

[0013] Furthermore, the reserved plug-in groove is a dovetail-shaped groove, and the limiting plug-in rib is a dovetail-shaped plug-in rib adapted to be plugged into the reserved plug-in groove, which is convenient for coordinated use to achieve rat-proofing of the quick splicing assembly.

[0014] Compared with the prior art, the beneficial technical effects of the utility model are:

[0015] In the present application, the ground-inserted piles at the lower end of the first cylindrical split are inserted into the soil near it, and then the limiting plug-in ribs of the second cylindrical split are aligned with the reserved plug-in grooves on the first cylindrical split. Along the extension direction of the reserved plug-in grooves, the ground-inserted piles at the lower end of the second cylindrical split are completely spliced ​​with the first cylindrical split, thereby achieving rapid positioning and assembly of the rodent-proofing device.
