Repair method of decayed tree hole

Abstract

The invention discloses a method for repairing a doted tree hole in a tree. The method comprises the following steps of: firstly removing rotten wood and foreign matters in the doted tree hole of the tree, sterilizing the tree hole with bactericide, scratching the edge bark part of the tree hole, spraying a scratched wound and the tree hole with gibberellin or rooting powder, and preparing filler by stirring perlite, cement and appropriate amount of water, wherein the weight ratio of perlite to cement is (15-20): (100-120); filling the tree hole with the filler, bundling the filler in the tree hole with a plastic film, removing the plastic film and a bundling material after curing, cutting the surface of the filler into a trunk shape with a cutter, coating the surface of the filler with paste which is prepared by stirring cement and ink or green pigment so as to form simulated bark which can be fixed on the surface of the filler, and stabbing the surface of the simulated bark with an iron nail at intervals so as to obtain small holes. The method has the advantages of being wide in source of raw materials, low in price and convenient in repairing and operation, and effects of water absorption and retention when water is little and water permeation when water is excessive are achieved, so that normal moisture is maintained for the tree, and the growth of the tree is resumed.

[0002] For various landscape trees such as ancient trees, large trees and garden street trees, due to various reasons such as long-term loss of care and mechanical damage during transportation, planting, repair and care, the exposed xylem is washed and soaked by rainwater and gradually causes insects to rot. It will cause a hollow inside the trunk, and various tree holes will be formed on the trunk, which will destroy the normal operation and storage of water and nutrients in the tree, and reduce the firmness and load-bearing capacity of the trunk. If it is not repaired in time, not only It will lead to the existence of environmental safety hazards, and in severe cases, it will cause the death of trees. Not only can they not perform their normal functions, but they may also cause potential harm to the personal safety of residents, or to properties such as buildings, electricity, and communication facilities. For large trees , especially ancient and famous trees, will not only destroy the changes in the ecological environment structure, but also affect its important historical and cultural significance

[0003] For the repairing method of above-mentioned decayed tree hole of tree, mainly contain traditional cement mortar method at present, this method adopts filling crushed stone, brick, plastics, cement and sandstone in wooden tree hole or erects steel skeleton in wooden tree hole, Refilling cement or mortar, the disadvantages of this traditional method are: firstly, sand, bricks and cement mortar are not only heavy in quality, causing excessive load on the trunk, shifting the center of gravity, and being airtight and watertight, so they will be damaged by wind and freezing. Severe weather such as snow and snow can easily cause trees to collapse and break; secondly, due to the hardening of the cement mortar layer, the expansion and contraction are small, and the growth of trees will easily cause gaps between the filler and the tree hole, and foreign objects can easily enter through the gaps. Wood tree holes, making it difficult for the trunk and filler to form a whole, and it is difficult to restore the original shape

[0004] For the repair method of decayed tree holes, materials such as polyester amine, polythioamine and polyester aerosol are also used for repair. This repair method has light weight and easy operation, but due to high cost, impermeability, Airtight, easy to accumulate water, and often cause the trunk to rot again, which is limited in practical application

[0005] At present, charcoal is also used as a filler to repair tree holes. Not only is the filling weight light, the water permeability is good, and it also has a bactericidal effect, but the price of charcoal is relatively high, and charcoal is not easy to fill in tree holes, and charcoal is water-absorbent in spring and winter. Strong, it is easy to cause water accumulation in the tree body, and the tree hole is easy to rot; it will cause water shortage in the tree body in summer and autumn, affecting the normal growth of the tree

There is also a method of using asphalt heating, sawdust, and fresh flowers to mix into a slurry and pour it into the tree hole for repair. This method will not only cause airtightness and watertightness, but the repair weight is heavy, and it is easy to form oily plant control agents. The immune ability of trees can easily cause trees to wither and die
