Operation method for transplanting wild big tree

Abstract

The invention provides an operation method for transplanting wild big trees, and relates to a method for transplanting wild big trees. The method comprises the following: a step of cutting off lateral roots, which is to take a trunk as a center and ditch taking the radius which is 3 to 4 times of the diameter of breast height, and a soil ball formed by ditching is in a reverse trapezoidal shape with big top and small bottom; a step of promoting new roots, which is to erect a row of wood boards serially connected by use of linen threads along a middle boundary of ditch width, spray root cuts with root power water on the side near the soil ball, spray the soil ball with root rot liquid medicine, backfill a mixed matrix of moss and river sand, backfill and tamp soil in layers on the other side; a step of cutting off a taproot, which is to ditch along the outer side of the wood boards after absorption roots are formed on the root cuts in next year, cut off a thick root and form a soil ball which is surrounded by the wood boards and is in a reverse circular truncated cone; a step of bunching the soil ball, which is to use straw ropes to bunch the basal part of a big tree and then nail guard plates; a step of lifting and unloading the big tree into a planting hole dug in advance after lifting and transporting the big tree to a destination; and a step of fixing and planting, which is to place the tree into the hole, remove the straw ropes and wood board binding materials and fill the hole with soil. The method can ensure that the survival rate of transplanted big trees is nearly 100 percent, thereby greatly improving environment greening ratio.

Description

technical field [0001] The invention relates to a hard paving method suitable for running water to continuously scour the ground for grass planting and landscaping. Background technique [0002] In urban landscaping or tree protection, it is often necessary to transplant wild trees. However, transplanting large trees is not an easy task, and it is a highly technical job. Deciduous trees with a diameter at breast height of 20 cm or more, evergreen trees with a height of 6 m (or a diameter at breast height of 15 cm) or more, and shrubs with a crown width of 3 m (or a height of 4 m) or more are regarded as large tree transplants. Due to the age of the big tree, the stage development is old, the regeneration ability of the cells is weak, the root system damaged during the excavation and planting process is difficult to restore, and the new root generation ability is poor. Especially because the wild big tree grows for seed reproduction, the main root system is developed, the la...

Problems solved by technology

According to this method, when the big tree is dug, the absorption roots of the soil ball are seldom, and many corks are serious, and the Kjeldahl band has prevented the absorption of water, and the absorption function of the root system has obviously declined; the survival rate when transplanting for the first time Only about 40%, the survival rate of about 40% is a waste of plant resources. Due to the low survival rate, it is difficult to popularize and apply in a large area, and the economic and social benefits are all low.
