Problems solved by technology

Because a series of operations such as transplanting and artificial planting will cause a large degree of damage to the root system, branches and leaves of the arbor, therefore, fine maintenance is required after transplantation, which leads to slow plant recovery after planting and cumbersome maintenance and management.

Embodiment Construction

[0023] The construction method of the arbor tree ball isolated island method soil in situ improvement and repair of the present embodiment is characterized in that the construction method comprises the following steps:

[0024] Step 1, Arbor shaping and pruning: Before the improvement operation, the trees need to be pruned and shaped to remove dead branches, diseased and insect branches, over-dense branches, elongated branches, and flower buds. 1 / 4;

[0025] Step 2, arbor brace reinforcement: For the pruned arbor, use steel wire 2 braces to brace the tree body. The height of the tie on the steel wire is located at 2 / 3 of the height of the tree, and a Pull the rope, on the arbor;

[0026] Step 3, Reserve the tree ball island: Determine the reserved size of the tree ball island 3 according to the size of the arbor specification, take 10-15 times the diameter of the arbor as the reserved size of the tree ball island, and the maximum reserved size of the tree ball island is not ...

Abstract

The invention discloses a construction method of arbor tree ball island method soil in-situ improvement and restoration. The construction method includes the following steps of 1, arbor pruning; 2, arbor tension brace reinforcing; 3, reserving of a tree ball island; 4, digging of an improvement hole; 5, arrangement of annular drainage ditches; 6, arrangement of air-permeable observation pipes; 7, soil formula improvement; 8, improved soil backfilling. Stacked soil obtained in the step 4 of digging of the improvement hole is scarified, aired, subjected to impurity removal and broken, then an improvement medium is added in proportion, the materials are turned over and stirred to be uniform, and improved soil is obtained. The improved soil obtained in the step 7 is backfilled into the dug improvement hole, and the backfilled improved soil is layered and tamped. According to the method, arbor soil is improved and restored through in-situ soil improvement operation, the procedures of balling up, wrapping, hoisting, transporting, heeling-in and the like relevant to tree transplanting are omitted, the influence of improvement construction on original arbor is reduced, and the survival rate of improved arbor is increased.

Description

technical field [0001] The invention belongs to the field of garden soil improvement, and in particular relates to a construction method for soil in-situ improvement and restoration by the arbor tree ball isolated island method. Background technique [0002] Soil is the basis of plant growth, and its various physical and chemical properties are directly related to the healthy growth of plants and the formation of plant community landscape effects. With the opening of green spaces and the impact of human activities, more and more green spaces have soil compaction, compaction, insufficient fertility, and even soil pollution, which seriously affects the growth of green plants and the landscape effect of green spaces. Soil improvement can improve soil physical and chemical properties, increase soil fertility, and create a good growth environment for garden plants, which is of great significance. In the traditional soil improvement construction, it is necessary to transplant and...
