Problems solved by technology

[0004] 1. Influence of internal factors
[0005] (1) Physiological functions of ancient trees are weakened. The physiological functions of ancient trees decline with the growth of tree age, and the vitality is weakened. The aging of tree age makes the ability of roots to absorb water and nutrients less and less able to meet the needs of the aboveground parts, resulting in the loss of internal physiology. Balance, some branches gradually wither and die
[0006] (2) Tree holes affect the nutrient transmission of ancient trees. The formation of tree holes in ancient trees is mostly caused by man-made, natural disasters, or pests and diseases. , and gradually expand inward and up and down, forming tree holes. Most of the old tree holes have not been treated, or a large number of concrete repairs are used to repair the tree holes, resulting in the weakening of ancient and famous trees.
[0008] (4) Root rot. Due to the hardening of the ground around the old tree or the construction of buildings, too much soil or garbage has accumulated at the base of the trunk. The root system of the old tree has been damaged and has poor breathing. The ability to absorb water and nutrients is weakened, resulting in dry branches and leaves
[0009] 2. External factors
[0011] (2) Human factors: ① Poor air permeability of the roots, leading to poor air permeability of the roots of ancient trees and famous trees. The second is that no space was left for the growth of old trees during construction, which affected the root systems of old trees growing in front of and behind the houses. The third is the impact of human activities. The impact of activities is relatively large, resulting in serious soil compaction; the fourth is that the trunk has too much soil, the roots of old trees are covered with too much soil, and the roots are not well ventilated
②The surrounding ground environment is not good. There are three main reasons for the poor ground environment around the old trees. One is soil pollutants. Plants with well-developed root system, strong germination and fast growth=seriously affect the lighting of ancient trees and cause the soil around the old trees to be poor; Poor ventilation or waterlogging
③ Unscientific fertilization and soil nutrient imbalance are the main reasons for the weak growth of trees
[0014] 3. Untimely first aid, old trees are damaged and cannot be treated in time, which is also the main factor for the weakness of ancient trees

Embodiment 1

[0036] Ancient tree name: Sophora japonica, Renjiamiao Village, Pingdu, Qingdao City, Shandong Province, 510 years old, the tree is hollow, with dead branches in the crown, it is located in an abandoned courtyard, surrounded by tall trees, overgrown with weeds, and trees beside the ancient trees. There are abandoned walls, courtyard walls and gatehouses, and the surrounding environment of ancient trees is poor, with yellow leaves and less flowering and fruiting.

[0037] Conservation and Rejuvenation Programs:

[0038] 1. Renovation of the ground environment

[0039] Clean up abandoned gatehouses, courtyard walls and other buildings next to the old trees, cut down trees, weeds and shrubs such as paper mulberry within a range of 5 meters from the canopy of the old trees. Trees and other trees are cut off roots and properly pruned. However, the tree is close to residential houses, and attention should be paid to the safety of surrounding houses when clearing the mulberry tree ...

Embodiment 2

[0064] The tree species tassel is 500 years old. It is located in the southwest of the village committee of Caomiaotou Village. In the tree pond, 20cm of soil is placed in the tree pond. In recent years, there are many dead branches and the tree vigor is weak.

[0065] Conservation and Rejuvenation Programs:

[0066] 1. Renovation of the ground environment

[0067] Clean up the tree pond next to the old trees and the mound around the tree, with an area of ​​40 square meters and a height of 30 cm.

[0068] 2. Soil improvement

[0069] Deeply plough the soil around the old tree, with a length of 5m from north to south, 5m from east to west (with the trunk as the center), and a depth of 0.4m, sieve the soil, and remove bricks and debris in the soil.

[0070] 3. Root ventilation measures

[0071] (1) Excavate long rejuvenation trenches and dig six rejuvenation trenches: uniformly 3m in length, 0.6m in width, 0.6m in depth and 0.8m in depth, carry out pesticides, insecticides a...

Embodiment 3

[0087] Tree species: Ginkgo biloba, 1385 years old, both ancient ginkgo trees have dead branches on the upper part of the canopy, and few new shoots sprout, some branches wither at the tips; The edges are withered and curled; the ginkgo fruit is obviously too small and the phenomenon of falling off is serious; the tree has many and large nodules, and the nodule area exceeds 50% of the surface area of ​​the tree; the branches are rotted prominently; the roots are rotted, and the tree is in poor growth condition; large Severely drooping branches are at risk of splitting.

[0088] Conservation and Rejuvenation Programs:

[0089] 1. Renovation of the ground environment to remove Ophiopogon japonicus and sundries in the tree pond.

[0090] 2. Soil improvement

[0091] (1) Deeply dig the soil in the tree pond to a depth of 0.4m. The original soil is sieved to remove gravel debris. Improve the soil in the ancient tree protection area, add beneficial bacteria to improve the physic...

Abstract

The invention provides a method for protecting and rejuvenating ancient and famous trees. The method comprises the steps of restoring the ecological environment of the ancient trees, improving soil fertility on the basis of soil detection, improving root breathability, repairing root system damage, repairing tree bodies and wormholes, protecting the tree bodies, arranging tree crowns, preventing and treating diseases and pests and performing informatization monitoring protection. According to the method for rejuvenating the ancient trees, all links of rejuvenation of the ancient trees are optimized, the rejuvenation of the ancient trees is guaranteed through corresponding methods and measures, the method is used for rejuvenating the ancient trees, the effect is obvious, facilities are simple, the rejuvenation success rate is high, and the method is particularly effective for rejuvenating the endangered ancient and famous trees with serious weakness.

Description

technical field [0001] The invention belongs to the technical field of ancient tree protection and restoration, and more particularly, particularly relates to a method for protecting and rejuvenating ancient and famous trees. Background technique [0002] An ancient tree is a tree that has grown for hundreds or even thousands of years and cannot be reproduced once it dies. Ancient trees are precious treasures left to us by history, and are non-renewable and irreplaceable living cultural relics. To protect an ancient tree is to protect a history of natural and social development. An excellent germplasm gene bank is also to protect a human and natural landscape. To protect ancient trees is to protect the environment on which human beings live, and to protect the precious wealth left by ancestors to their descendants. [0003] Reasons that affect the aging and death of ancient trees: [0004] 1. Influence of internal factors [0005] (1) The physiological function of the anc...
