Description

Technical Field

[0001] The invention relates to a pruning device, in particular to a pruning device and a method for preventing wind damage to trees in coastal areas, belonging to the technical field of preventing wind damage to trees in coastal areas. Background Art

[0002] With global climate change and natural geographical reasons, the frequency and intensity of various types of wind disasters are showing an increasing trend. The frequency and intensity of typhoons in my country's southeastern coastal areas have increased significantly. Wind damage not only causes huge damage to forest ecology and forestry production, but also causes roadside trees in cities and ancient trees in rural areas to break and fall, threatening the safety of people around them, and damaging property and culture. Related issues have put forward higher requirements for the protection of forestry resources and the maintenance of municipal services.

[0003] Pruning is an indispensable maintenance topic for trees. Appropriate and timely pruning can not only correct and repair tree defects, make them fit in with the surrounding environment and form a good tree mechanical structure, but also greatly improve the tree's wind resistance, enhance public safety, and protect the lives and property of citizens.

[0004] The breaking and falling of trees under wind damage is essentially a mechanical behavior of trees. Whether trees will break and fall under strong winds depends on the wind force, the wood strength of the tree, and the fixing force of the root-soil plate. When wind pressure acts on the tree crown, the wind force formed is not only related to the wind speed level, but also to the wind-absorbing area and ventilation rate of the tree crown. Therefore, increasing the pruning of tree crown cavities can increase the ventilation area of ​​the tree crown.

[0005] Common pruning methods include tunnel pruning and thinning. It is a pruning method that cuts branches from the base of the branches, forming channels in the crown to reduce the density of branches, forming wind tunnels, and evenly distributed branches, improving the ventilation and light transmission ability of the tree, so that the holes are evenly distributed after pruning.

[0006] However, existing tree pruning is done manually based on experience, and most of them only take into account the surrounding environment, greening aesthetics, and pest and disease pruning, without considering ventilation. The related labor cost is high, the construction time is long, and it is not possible to optimize the pruning of trees in combination with the different environments in different regions. There are many construction tools, and the pruned tree branches are not easy to collect and transport. Therefore, a pruning device and method for preventing wind damage to trees in coastal areas are proposed. Summary of the invention
