-- Protecting ancient and famous trees, Shandong Baolufeng is in action.
Ancient trees grow above the wilderness, standing in the middle of the years, circle the annual rings, circle the fireworks of the world, mottled bark, and record the vicissitudes of the world. It resembles an old man, dying in his twilight years. During this period, the vitality of ancient trees declined, and they were easily affected by the environment and led to death. Therefore, the conservation and rejuvenation of ancient trees and famous trees must be careful and meticulous, and create a good growth environment for them to the greatest extent.
1. Maintain the original ecological environment
Ancient trees have survived in the same place for thousands of years and have adapted to the local ecological environment. It is best not to change its ecological environment arbitrarily. For example, do not build around the ancient trees or dump garbage and sewage, so it is easy to change the light, water quality and soil, resulting in the destruction of ancient trees.
2. Maintain the permeability of the soil
Ancient tree canopy is large, good shade, tourists like to cool under the tree, ornamental more, easy to cause the ancient tree root system of the upper soil compaction, permeability becomes poor. The respiration and expansion of the root system will be hindered, affecting the growth of ancient trees, and the ancient trees should be frequently loosened during the growing season or appropriate amounts of grass shavings and humus should be applied to improve the soil structure, so that the root system and aerobic microorganisms can grow normally. Soil that cannot be repaired is recommended for soil replacement.
3. Strengthen fertilizer and water management
Ancient trees grow in the same location all year round, the soil will lack certain trace elements, such as not timely water and fertilizer management, will affect the growth of trees. When fertilizing, it should be reasonably matched according to the type of ancient tree and the type of fertilizer, and the light fertilizer should be applied frequently. When the soil is dry, it should be replenished in time, and when there is water accumulation, it should be drained in time.
4. Pest control
Ancient trees grow in a decadent manner, have poor resistance to stress, and are susceptible to diseases and insects, so it is necessary to strengthen inspection and early prevention and treatment.
5. Repair holes and treat injuries
The wood of ancient trees is not easy to decay, resulting in jagged tree holes, affecting the growth of ancient trees, and should be repaired in time:
(1) Clear the tree hole.
Clean the hole surface with a wire brush or brush and spray the inner wall 2 times with a 1:30 aqueous solution of copper sulfate at half an hour interval. There is a wormhole inside the cave, which can be injected with a 1:50 solution of oxidized leguo, and then coated with water asphalt preservatives on the inner wall.
(2) Fill in the holes
Polyurethane and polysulfide sealants can be used as a patch, mixing with polyether and polyureth in a ratio of 1:1.35 until foaming is formed.
(3) Appearance modification.
In order not to affect the beauty of the ancient trees, in accordance with the principle of following the slope and taking shape of the trees, the appearance of the ancient trees is beautified and the original appearance is restored by means of bark or partial modeling
6. Prevent natural disasters
Tall ancient trees need to be equipped with lightning rods to avoid damage to the ancient trees caused by fire caused by lightning strikes. The growth is uneven and should be protected by a bracket on the weak part. Usually, attention should be paid to regularly checking the growth of trees, pruning dead branches in time and cleaning.
7. The renewal and rejuvenation of ancient trees
The restoration of trees that are weak and dying should be strengthened. When the branches on the periphery of the canopy are aged and dead, they are pruned with retraction and the dead branches are cut off for renewal. Strengthen water and fertilizer management. Tree species with strong germination ability can be renewed by the root system. In addition, for ancient trees with weak tree strength, the bridging method can also be used to restore their vitality.
