Method for patching big tree defective tree bark by small tree trunk through small tree transplanting

Abstract

The invention relates to a method for patching a big tree defective tree bark by a small tree trunk through small tree transplanting. The method is characterized in that the small tree trunk leans against the position of the big tree defective tree bark; the function that the tree bark gradually grows up is utilized; a big tree and a small tree are mutually extruded in the growing-up process; then, the barks of the two trees grow into a whole; the effect that the small tree trunk patches the big tree defective tree bark is achieved; the tree trunk cannot continuously rot; the big tree becomes a whole tree. By the method, the lives of many excessively big trees, memorable big trees and old trees with long tree age are saved.

Description

technical field [0001] The invention belongs to the field of maintenance and management of tree growth in urban forests and treatment of diseased trees. Background technique [0002] Street trees, square trees, and garden trees have become the favorites of passers-by and leisure people, especially the bigger trees, trees with more shade in summer, and commemorative old trees are more popular. Trees have a long lifespan. Among the greening plants in the city, trees have the longest lifespan. People especially like big trees. The bigger trees and the older trees are more popular. Most of them are street trees. Streets in cities have conditions or high-grade roads are planted with street trees, but the trees in the city suffer the most three types of damage; one is the trunk man-made damage, the street tree suffers the most human-made damage, and the most damaged part is the bark of the trunk that is quite high. The bigger the tree, the more man-made damage it will suffer accu...

Trees have a long lifespan. Among the greening plants in the city, trees have the longest lifespan. People especially like big trees. The bigger trees and the older trees are more popular. Most of them are street trees. Streets in cities have conditions or high-grade roads are planted with street trees, but the trees in the city suffer the most three types of damage; one is the trunk man-made damage, the street tree suffers the most human-made damage, and the most damaged part is the bark of the trunk that is quite high. The bigger the tree, the more man-made damage it will suffer accumulatively. There are also vehicle collisions and equipment collisions. Self-repair, after many trees are seriously injured, the bark cannot grow and close, and the woody part of the trunk that loses the protection of the bark begins to rot after a long time. The trunk of some trees rots into a hollow, and the serious big tree dies

Second, trees are also harmed by insect pests, especially street trees and lively square trees. Because of the bustle of people, there are almost no natural enemies of insect pests. Tree pests in cities are completely managed by greening personnel. Once management is interrupted or negligent, serious insect pests are also endangered. In the growth of trees, people often find that the big tree is infested by insects, the trunk and branches have been eaten by insects, and even the strong wind has broken the trunk or branches, and only then can they see that the broken part is eaten by insects. When people find pests, they also spray pesticides to kill the pests, and there is nothing to do with the hollowed trunks

Third, it is improper maintenance and repair of branches. When large branches are broken by the wind, there are also artificially broken branches, and the dead branches that are naturally eliminated at the bottom of the crown of the big tree. No one repairs them in time. The bark at the broken branch cannot grow tightly, and the core of the branch begins to rot after a long time, and it rots all the way to the center of the trunk. There are also branches left for repairing large branches that are too long, and the branches have died long ago, but they have not fallen off. The bark cannot grow tight, so it starts to rot from the dead branch to the center of the trunk. These three points exist in all cities

[0006] There are a lot of sycamore trees in Nanjing, and it is also the earliest city in China to plant large-scale trees. Many sycamores are nearly 90 years old. Because the bark is broken, there are many trees with rotten trunks. In recent years, including construction reasons, the annual There are large plane trees that have been eliminated every year, and now we see that the hollows of the rotten cores of the plane trees are poured with cement, and the hollows of other tree species are also filled with cement as a repair. In recent years, the cement has been painted. The same method is used in cities. This method cannot make the bark grow and close, but only improves the appearance. The cement absorbs water when it rains, and evaporates water when it is sunny. The cement also has chemical components, which will affect the sap in the trunk. Yes, there is a gap between the cement and the repaired wood, and if rainwater seeps in, it will continue to rot the wooden trunk of the big tree. At present, plastic foam is used on the bad bark. The plastic foam is well sealed, and no rainwater will seep in. The tree hole, but the tree hole is still empty. The plastic foam is too soft to set off the growth of the bark, and it cannot bear the weight of the trunk and branches. The exposed plastic foam is very soft and cannot withstand the impact of foreign objects. The tree is still growing. How long will the foam seal? These two tree pruning methods in Nanjing did not consider the growth of the bark at all, and did not create conditions for the bark to grow and close. It can only be said that the tree hole was filled.

Previously, I invented a method of repairing a large tree hole with cement wrapped in a plastic bucket. After repairing the tree hole and adding wood chips to cover the hole, creating conditions for the bark to grow and heal, the application number (201710309964.8), but the tree hole is too large, especially the trunk If half of the bark is missing, or the length of the bark defect is more than 1 meter or 2 meters, it is still very difficult to close the bark of the big tree itself.
