By the method, a plurality of large trees, commemorative large trees and ancient trees with long tree ages can be saved.
Description
Technical Field
The invention belongs to the fields of maintenance and management of urban forest tree growth and treatment of diseased trees.
Background
Street trees, square trees and courtyard trees become the favorite of pedestrians and leisure people, and particularly, larger trees, trees with more shady shades in summer and ancient trees with commemorative significance are popular with people. The tree life is long, the tree life in the plants for greening in the city is the longest, people particularly like big trees, the bigger trees and the trees with longer tree ages are more popular, the most trees are street trees, streets in the city are conditioned, or street trees are planted on high-grade roads, but the trees in the city are most damaged; firstly, the trunk is artificially injured, the street trees are injured most artificially, the most injured parts are barks of trunks which are quite high as people, the larger the trees are, the more the artificially injured trees are, the vehicle collision and the instrument collision exist, (the trees in other places are injured little, and the forests are almost not) at present, no remedial measure exists, the trees basically grow and repair by themselves, after a plurality of trees are seriously injured, the barks cannot be folded, the wood parts of the trunks losing the bark protection for many years begin to rot, the trunks of some trees are rotten to be hollow, and the serious trees die. Secondly, the tree still receives the harm of insect pest, especially street tree and the square tree that is hot, because people's heat is very loud, almost has not had the natural enemy of insect pest, and urban tree insect pest is managed by afforestation personnel completely, in case the management is interrupted or neglected, serious insect pest also threatens the growth of trees, and often people find that big tree has the insect pest, and the trunk branch has been eaten away by the worm, and more has the strong wind to scrape big tree trunk or big branch and has been cut off, just sees that the rupture department is eaten away by the worm, even people find the insect pest, also sprays the pesticide and kills the pest, also has no way to the trunk that moths is empty. Thirdly, when the big branches are blown off by wind and broken artificially, and dead branches naturally eliminated from the lowest part of the crown of the big tree are not repaired by people in time, the broken branches are cleaned regularly and left for use, so that the bark at the broken branches can not grow tightly, the branch core starts to rot at the broken branches for a long time and is rotten to the center of the trunk, the branches left after the big branches are repaired are too long, the branches die early but do not fall off, and the bark can not grow tightly, so that the dead branches start to rot and are rotten to the center of the big tree all the time, and the three points exist in all cities.
All trees are composed of roots, trunks, barks, branches and leavesThe tree comprises trees, flowers and fruits, leaves, flowers and fruits are arranged on branches, the leaves, flowers and fruits grow each year, wherein the roots, trunks and branches of the trees are all wood with annual rings of one circle, the wood is wrapped with barks, the roots, trunks and branches grow in the same length and do not fall off, the difference is that the roots, trunks and branches have different thicknesses, the roots are in the soil, and the trunks and branches are in the air; the bark is connected with roots, trunks, branches, leaves, flowers and fruits, the bark is the life of the tree and has 4 functions, namely, the bark is used for circularly conveying water and nutrients up and down; secondly, the wood growing into roots, trunks and branches grows big year by year; thirdly, the roots, the trunks and the branches are protected from being damaged by the outside; fourthly, leaves are grown, blossoms and fruits are grown at the branch parts, the trees can grow completely without bark, but the bark is damaged firstly, the damaged bark is small, the bark can restore the tree to be long and tight, (the trees have different capacities of growing and are slow at present), once the trees are damaged greatly, the damage of the bark exceeds the capacity of restoring the tree to be long and tight, the wood part without bark protection can rot for a long time, the serious trunk is rotten and empty, the big trees can fall down, the whole trees can die, the trees can grow well for maintaining the big trees in cities, and the bark is protected firstly to be intact. The sycamore has the function of strong bark self-growing, and the largest diameter of sycamore can be seen in numerous sycamore walk trees and courtyard trees in Nanjing
The tree is characterized in that a tree branch with the length of more than one centimeter is sawn off, the bark at the sawn off part is well long, once the bark is well long, the tree is a complete tree, the capacity of the tree is well long, and people rarely create conditions for the well-long bark of the tree.
In Kunming lake of Beijing Yiheyuan, nineteen willows of the dry-long era are protected particularly because of the long age and are trees of royal gardens, wherein a plurality of trunks have fake barks, and yellow foams exist in the fake barks, so that the artificially repaired barks are obviously beautiful and look far like a complete big tree, the repair is only to cover up the wounds of the willows, the wounds of the willows are not repaired actually, and the wounds and the fake barks cannot perform life circulation.
As long as the larger the tree, the older the tree, the more cases of trunk hollowing occur, which is even thought to be normal, although protection may be performed, it may be many cases that the function is not large and the hollowing of the tree is still slow. The first of the injuries is street trees, and the second is park trees, square trees and garden trees, and in any case, people can hurt trees in places where people arrive, the more people the trees are, but people like big trees, even if the big trees are rotten to form big holes, even if some big trees are dead, people can support the trees by the method.
The large-tree-shaped sycamore trees in Nanjing are many, the earliest city planted in large scale in China is also provided, many sycamore trees have the age of nearly 90 years, the bark is damaged, the trunk rotten core trees are many, the old trees have obsolete sycamore trees in recent years including construction reasons, the cement is poured into the cavities of the core of the large-tree-shaped sycamore trees, the tree holes including other tree species rotten cores are also filled with the cement for repairing, the cement is painted in recent years, the method is also used in many cities, the bark cannot be folded, the method only plays the role that the appearance is good, the cement absorbs moisture when raining, evaporates moisture when sunny days, the cement also contains chemical components, the tree sap in the trunk is influenced, gaps exist between the cement and repaired holes, rainwater seeps into the trunks, the trees can continuously rot, and the plastic foam is formed at the damaged bark in the prior art, plastic foam is well sealed, rainwater cannot seep into the tree hole, but the tree hole is empty, the plastic foam is too soft, cannot support the tree bark to grow tightly, cannot bear the weight of the tree trunk and the tree branches, the plastic foam exposed outside is very soft, cannot stand the collision of foreign objects, the tree still grows, and how long the foam can be sealed? The two tree pruning methods in Nanjing do not consider the growth of the bark at all, do not create conditions for the folding of the bark, and only can supplement tree holes. The invention relates to a method for repairing a large tree hole by using plastic barrel cement, which is used for repairing the tree hole and covering a hole opening with wood chips to create conditions for healing the long bark, and the application number (201710309964.8) indicates that the bark of a too large tree hole, particularly the bark of a trunk lacks half side, or the bark defect length reaches more than 1 meter and 2 meters, and the bark of the large tree is difficult to be closed by the self length of the large tree.
