Description

Technical Field

[0001] This utility model relates to the technical field of tree protection devices, and in particular to a tree protection device to prevent rabbits from gnawing on trees. Background Technology

[0002] In the process of modern forestry development, the healthy growth of trees is of great significance for maintaining ecological balance, supplying timber resources, and creating landscapes. Whether it is large-scale forest cultivation, street trees and park landscape trees in urban greening, or economic tree species in orchards and nurseries, all require comprehensive protection measures to resist various biological attacks. Among them, the problem of wild rabbits gnawing on trees is becoming increasingly prominent, bringing many challenges to forestry production and ecological construction. At the same time, wild rabbits are herbivores, and in the natural environment, when food is scarce in winter, tree bark and tender branches become important food sources for them. The damage caused by wild rabbits to trees should not be underestimated. For young trees, wild rabbits gnawing on the bark may sever the tree's vascular tissue, hindering the transport of water and nutrients, leading to stunted growth or even death. For mature trees, frequent gnawing not only affects the tree's appearance and reduces its ornamental value, but also weakens the tree's resistance to diseases and pests, making it more susceptible to pathogens and pests, thus affecting the stability of the entire forest ecosystem.

[0003] Currently, tree protection devices against rabbit grazing on the market mainly consist of a protective body and fixed components. To combat the damage caused by rabbits grazing on trees, traditional protective methods are diverse. Early on, people mostly used manual methods to drive them away, but this method was inefficient and unsustainable, failing to address the root cause of the problem. Subsequently, some chemical agents were applied for protection, such as applying repellents to the tree trunk. However, the effectiveness of chemical repellents is greatly affected by environmental factors; rain, wind, and sun exposure can cause their effective ingredients to be quickly lost, requiring frequent reapplication, increasing labor costs and the potential environmental pollution risk of chemical agents. Furthermore, some chemical agents may have negative effects on the trees themselves, such as affecting their normal growth and metabolism. Regarding physical protection measures, common methods include wrapping the base of the tree trunk with plastic film or straw rope. However, plastic film has poor air permeability, and prolonged use may lead to abnormal local temperature and humidity in the trunk, affecting the tree's respiration. While straw rope has some air permeability, it is easily bitten by rabbits. These traditional protective methods are often ineffective due to their short lifespan and need for regular replacement. Furthermore, they lack versatility, exhibiting varying protective effects depending on the tree species, growing environment, and rabbit population density. Many existing tree protection devices on the market are also severely inadequate in addressing the diverse sizes of trees. Traditional devices are often designed with fixed dimensions and extremely limited adjustment ranges. For example, common trunk-wrapping structures, such as plastic film wrapping, have fixed widths and lengths at the time of purchase. When wrapping thinner trunks, this results in numerous redundant folds, affecting the protective effect and potentially leading to microbial growth and harming the tree. When used on thicker trunks, the insufficient size prevents complete coverage, leaving gaps for rabbits to gnaw on. Similarly, some devices using metal-wood protective cylinders have fixed inner diameters, only suitable for trunks of specific thicknesses, rendering them ineffective for trees outside this range. Summary of the Invention
