Method for reserving primeval big trees in process of terrain reform

Abstract

The invention relates to a method for reserving primeval big trees in the process of terrain reform. According to ground elevation requirements of the terrain reform, a material filling well surrounding a trunk is arranged on the surrounding of the trunk of a primeval big tree, the material filling well is provided with gaps, planting soil is filled on the periphery of the material filling well to shape new terrain, the primeval big tree is pruned or is not pruned, one or more permeable hoses are arranged inside the material filling well, preferably, the number of the permeable hoses is two or three, filling particles which are permeable and can support the permeable hoses are filled in the permeable hoses, the wall of the material filling well comprises a filling layer which is filled with particle materials and is permeable and ventilation, and the particle materials comprise porcelain granules, nut peels and crushed stones. By the aid of the method, the shape and the landscape arrangement of the new terrain are not affected in the process of the ground elevation, the normal circulation of the big tree is guaranteed after processing, and the big tree can grow healthily. Besides,the method has the advantages of being simple in operation, wide in material source, low in cost and broad in application range.

Description

Technical field [0001] The invention relates to a method for retaining original big trees, in particular to a method for retaining original big trees in the process of terrain reconstruction, and is mainly used in the process of improving terrain. Background technique [0002] At present, as people's requirements for ecological harmony and living environment continue to increase, garden engineering is developing day by day, especially for the quality, function and effect of the landscape environment. In some garden engineering projects, it is necessary to reshape the terrain or handle the elevation difference, and at the same time, some old trees and big trees must be preserved, such as: trees with high age, rare and precious trees, with historical value or important memorial significance According to relevant regulations, the management and conservation of famous trees and old trees that are strictly prohibited from felling or migration, especially those that are not easy to gen...

In some garden engineering projects, it is necessary to reshape the terrain or deal with the height difference, and at the same time, some old trees and large trees must be preserved, such as: trees with high age, rare and precious trees, with historical value or important commemorative significance According to the relevant regulations, it should focus on management and maintenance, and it is strictly forbidden to cut down or relocate the famous old trees, especially the deciduous trees or evergreen trees with adventitious roots, such as locust trees, etc., which are easy to cause damage in a short period of time if they are transplanted. Death, direct terrain shaping is prone to trunk breathing difficulties, weak growth, until the metabolic cycle of the tree body is blocked, resulting in the slow death of large trees

How to ensure that the above-mentioned large trees can circulate and metabolize normally and grow robustly after transformation is a topic of great concern to various garden departments, but at present, there are no effective preservation measures
