Method for performing surgical straightening reshaping on large-size bent-trunk tree, trunk straighter and use method thereof

Abstract

The invention provides a method for performing surgical straightening reshaping on a large-size bent-trunk tree. By the adoption of the method, a low-value unmarketable tree can become a high-value-added saleable tree, and therefore the economic benefits of tree farmers can be increased substantially. According to the method, fertilization for maintenance, pruning for weight loss, surgery for straightness restoration and fixation for recovery are sequentially performed on the tree to be reshaped, and specific requirements are put forward for all the steps. A wedge-shaped block is cut off from the outer side of the bent part of a trunk by the adoption of the surgical cutting method, the bent part of the bent trunk restores straightness by utilizing the elastic deformation amount and wedge-shaped space formed through cutting off, flexible gradual straightness restoration is performed on the position, on the upper segment of a cut, of the trunk through a trunk straighter, the lever principle is used in the straightness restoration process, an operator exerts flexible pressure on the force exertion end of a straightening lever in the trunk straighter to prevent the situation that in the straightness restoration process, due to over-exerting, the trunk is fractured, or bark is pulled to be snapped, and therefore the success rate of surgical straightening of the bent trunk of the large-size reshaped tree can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of tree planting and cultivation, and more particularly relates to the trunk correction technology. Background technique [0002] Beech is a large tree with the characteristics of light-loving, good material, long life, resistance to diseases and insect pests, wind resistance, smoke pollution, etc., and has a beautiful tree shape. species. [0003] Beech is a false two-branched tree species. If the branches are not pruned in time, it will easily form crutches. The main stem of natural beech trees is rarely straight and straight. Therefore, it is rarely used in urban and rural greening; but due to This tree species is not easy to be infected by diseases and insect pests, and has the characteristics of high survival rate after planting. In addition, people's requirements for selected tree species for urban greening have changed in recent years. In the past, people always liked to choose evergreen tree species...

AI Technical Summary

Problems solved by technology

[0004] First, it blocks sunlight in winter and affects people's daily life;

[0005] Second, in winter rainy and snowy weather, because the cold snow under the trees is not easy to melt, it is very easy to cause traffic accidents

[0006] Third, evergreen trees have poor wind and snow resistance, which can easily cause broken branches or lodging, affecting traffic and people's normal travel

[0009] Although Chinese patent 201110219654.X discloses a kind of pruning and shaping method of beech tree, this method is to the traditional shaping method of 2~3 centimeters (below tree age 4 years) sapling to diameter at breast height, and this method adopts artificial wringing method, Bind and pull the trunk and branches. Although this patented method has certain benefits for raising beech trees to cultivate straight stem seedlings, the straight stem rate of beech trees is not high. When the beech tree grows to a diameter greater than 5 cm Unable to do anything when there is a bending defect
