Habitat rehabilitation method for big trees and ancient and famous trees

Abstract

The invention relates to the technical field of tree culture protection, in particular to a habitat rehabilitation method for big trees and ancient and famous trees. The method comprises the steps that 1) a selected tree growth index and site environment index are detected; 2) a soil physicochemical index is collected and detected; 3) a crown vertical projection range of the trees is collected, and a habitat rehabilitation range is determined; 4) weeds and waste are removed; 5) a flower base is rearranged, and the tree pit space is enlarged; 6) a hardened laying structure in the rehabilitationrange is chiselled away; 7) bad site soil is removed; 8) through a bactericide, the root system is sterilized and disinfected; 9) improvement soil is subjected to backfilling; 10) a root growth promoting agent is subjected to layered pouring; 11) a supporting foundation is laid; 12) a surface laying structure is laid; 13) a flower base fence is arranged; 14) associated plants are planted; 15) a construction site is cleaned, and waste is removed. According to the habitat rehabilitation method, habitat rehabilitation is systematically monitored and improved, a good ecological environment is provided for site habitat rehabilitation, the weak trend for the growth of the trees is avoided, and a good long-acting promotion function is achieved.

Description

technical field [0001] The invention relates to the technical field of tree cultivation and protection, in particular to a habitat improvement method for large trees, ancient trees and famous trees. Background technique [0002] Big trees generally refer to deciduous trees with a diameter above 200 mm and evergreen trees with a diameter above 150 mm. Meaningful trees can be called famous trees. Habitat refers to the ecological environment on which species or species groups live. Site habitat has a very important impact on the growth of large trees, ancient trees and famous trees. The over-exploitation of ecological resources has caused varying degrees of interference to the plant growth environments such as gardens, forests, and forests. The habitats of large trees, ancient trees and famous trees have suffered varying degrees of damage. The main problems include: 1. The tree hole is narrow and small ; 2. The surrounding area of ​​the tree head is sealed by the hardened pav...

Habitat refers to the ecological environment on which species or species groups live. Site habitat has a very important impact on the growth of large trees, ancient trees and famous trees. The over-exploitation of ecological resources has caused varying degrees of interference to the plant growth environments such as gardens, forests, and forests. The habitats of large trees, ancient trees and famous trees have suffered varying degrees of damage. The main problems include: 1. The tree hole is narrow and small ; 2. The surrounding area of ​​the tree head is sealed by the hardened pavement structure, resulting in poor air permeability, and it is difficult to supplement nutrients to the peripheral root system during daily maintenance, resulting in restricted root growth; 3. The growth space is occupied by buildings and surrounding associated plants; 4. Adjacent There are no flower bases or fence protection around the big trees and ancient and famous trees growing on the road, so they are easy to be damaged by impact; 5. The quality of the soil on the site is declining, and the problems of extreme acidity and alkalinity of the soil, poor air permeability, nutrient imbalance and pollution are becoming more and more prominent; 6. There are underground pipelines and underground pipelines at the bottom of large trees, ancient and famous trees, which lead to restricted root growth; therefore, from the analysis of site environment changes, the growth of large trees, ancient and famous trees is weakened due to the change and limitation of the living environment

[0003] Reconstruction of the unfavorable site habitats of large trees, ancient and famous trees has become the focus of the protection of large trees, ancient and famous trees. The habitat improvement of large trees, ancient and famous trees includes site soil improvement, expansion of tree holes, and transformation Measures such as pavement structure and construction of fences, among which soil improvement, transformation and hardening pavement structure, and construction of fences are mostly used in the rejuvenation measures of ancient and famous trees in practical applications. Therefore, it is necessary to replace the airtight pavement with air-permeable pavement during habitat improvement to increase the air and water permeability of the root system; for example, in 2004, Tang Youhua and Cheng Min laid air-permeable bricks on ancient trees in Shanghai by digging open the cement floor and cleaning the cement. For slag, garbage, etc., put 4-5cm of river sand under it to facilitate leveling, and then spread breathable bricks on it without pointing. Soil structure causes secondary adverse effects

Second, since the site soil is the basis for the growth of large trees, ancient and famous trees, the deterioration of soil quality has the most direct impact on the growth of large trees, ancient and famous trees. Therefore, it is necessary to improve the soil quality and fundamentally improve the habitat, such as In 2016, Liu Xiaohua and Xiang Jian proposed that the soil improvement of large and ancient trees can be carried out through technical measures such as setting up rejuvenation ditches, burying ventilation pavement and ventilation pipes, and replacing soil, but did not publicly describe other specific measures for habitat improvement

[0004] Generally speaking, there are more and more problems existing in the site habitats of large trees, ancient and famous trees, especially in areas with frequent resident activities, where the site habitats are obviously disturbed; A lot of work, but a complete and operational habitat improvement method is lacking
