DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a root wrapping material for transplanted trees and a method for planting and transplanting trees, and more particularly to a root wrapping material for transplanted trees that promotes the development of fine roots and a method for planting and transplanting trees using the root wrapping material for transplanted trees.

[0002]

2. Description of the Related Art Transplanted trees are required to cut a certain amount of roots when excavating from topsoil, and the amount of transpiration from leaves and the like becomes excessive compared to water supply from the cut roots. It is necessary to prevent tree planting damage. For this reason, branches and leaves have been pruned and reduced in weight. However, in tree planting on the roof of a building or an atrium, which has been increasing in recent years, the tree shape is particularly emphasized, and the pruning of branches and leaves is limited. Therefore, in order to guarantee the water supply corresponding to the transpiration, tree planting is excavated from the topsoil, the cutting root part is reshaped, and then buried again, and a temporary planting period is provided to obtain sufficient fine roots, and then replanting is performed. I have.

Conventionally, the above-mentioned rooting work required a high level of skill in discriminating between cut roots and non-cut roots, peeling of power roots and straight roots, etc. Excavating together with the root mortar, cutting all the roots outside from the root mortar reduces the above-mentioned skill, temporarily planting this root mortar with the root wrapping material, and after refining the fine roots again It is the situation that excavation and bedding material are stripped and replanted. As the root wrapping material, besides straw and como, those having a better rooting state than these, for example, those obtained by sandwiching a specially processed net with paper are used.

[0004]

However, in order to obtain fine roots suitable for survival after transplantation, a long temporary planting period of about one year is required, and roots are densely meshed around the inside of the root winding material. However, this often caused root rot, or the fine root penetrated the root wrapping material, and it was often necessary to cut a part of the obtained fine root.

The present invention has been made in view of these problems and the above-mentioned prior art, and an object of the present invention is to provide a transplant tree that can obtain a transplant tree with good survival in a short period of time without requiring any skill. An object of the present invention is to provide a root wrapping material and a tree planting transplantation method using the same.

[0006]

The root-wrapping material for transplanted trees according to the present invention solves the above-mentioned problems, and the gist of the invention is that the outermost layer of the lowermost layer of the root-wrapping material used for the rooting of transplanted trees is used. A biodegradable fiber inner covering material overlaid on the outer covering material, laying a soil layer on the inner covering material, and forming the soil layer with a water-soluble thin film. It is characterized in that it is covered, and the soil layer can be divided into a number of small chambers.

The tree transplantation method of the present invention is a method of transplanting a tree planting using the above-mentioned root tree material for transplanted tree. First, the tree plant to be transplanted is excavated from the topsoil, and a root pot is laid around the root tree for transplanted tree. A step of root-wrapping with wood, a step of burying the tree-planted tree with backlogging on the topsoil and temporarily planting, and then leaving the tree-planting on the topsoil with an outer covering material of the root-wrapping material for transplanted tree. Excavating and transplanting again with the root wrapping material other than the covering material.

[0008]

According to the root-wrapping material for transplanted trees of the present invention, fine roots reaching the soil layer through the thin film can be grown in the soil layer on the inner covering material. In addition, since only the covering material is overlapped on the outside and inside, these can be easily separated, and since the inside covering material is made of biodegradable fiber material, if the outside covering material is peeled off, the tree planting will be rooted. Can be replanted as it is. In addition, the thin film has water solubility and eventually assimilate into soil. If the soil layer is divided into a number of small chambers, the bias of the soil layer can be prevented.

[0009] Further, in the tree planting and transplanting method of the present invention, the above-mentioned root wrapping material for transplanted trees is used, so that the above-mentioned effects can be enjoyed in the transplanting step.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 shows a root wrapping material I for transplanted trees of the present invention.
The basic structure of the root wrapping material I is composed of an outer covering material 1, an inner covering material 2, an artificial soil layer 3, and a Japanese paper 4 as a thin film. The root winding material I is a disk-shaped layered body, and the outermost layer of an artificial woven fabric made of, for example, polyethylene or polypropylene as a synthetic polymer material, for example, a synthetic polymer material, which is rich in air permeability and drainage in the lowermost layer. 1 and an inner coating 2 made of a natural fiber material such as rice straw or coconut fiber which is corroded and decomposed after a certain period of time, that is, biodegradable rice straw and coconut fiber. An artificial soil layer 3 containing sand, foamed silica and calcium carbonate as a main component and containing a water-absorbing polymer and a chemical fertilizer is laid, and the soil layer 3 is surrounded from above by a water-soluble Japanese paper 4 and placed on the covering material 2. It has been firmly established. FIG. 2 is an enlarged partial cross-sectional view of the root wrapping material I. The artificial soil layer 3 is also vertically partitioned by Japanese paper 4 ′, and as shown by broken lines in FIG. It is divided into a small square room 3 '. The section of the artificial soil layer 3 can also be formed by vertical and horizontal quilting. The size of the root wrapping material I can be appropriately set according to the pot portion and the planting hole of the transplanted tree, but the planting hole preferably does not exceed about 3 m in diameter and about 1.5 m in depth. The thickness is preferably about 10 cm, and the side length of the small chamber 3 'is preferably about 30 cm.

Next, the steps of transplantation using the above-described root tree I for transplanted trees will be described. First, planting tree 10 from topsoil 20
1 and excavation (FIG. 3), cutting roots protruding from the root mortar 11 are arranged, and shaping such as removing natural soil attached near the root cut is performed (not shown). 11 is laid down using a straw rope 13 or the like (FIG. 4), and then buried back in the slightly expanded excavation hole 21. This state is shown in the schematic sectional view of FIG.

The tree 10 is provisionally planted after being protected from wind by a branch line 14 or the like. The artificial soil layer 3 of the root winding material I is the trunk 1
Compared to the natural soil 20 'around 0 ", it is formed so as to be rich in moisture and fertilizer components as described above, and the generation of fine roots 10' is greatly promoted. As a result, the temporary planting period is reduced to two to three months. It is possible to shorten the length of the fine roots 10 ', which has been a problem in the past, and to avoid root rot due to dense growth.Since a synthetic polymer material is used for the outer covering material 1, it is rich in air permeability and drainage, In addition, the water-soluble Japanese paper 4, (4 ′) decomposes and disappears during this period and assimilate with the soil.

After the elapse of the temporary planting period, the end 1 'of the outer covering material 1 is fixed with a pile 15 or the like, and then the transplanted tree 10 is pulled out with a crane or the like (FIG. 6). At this time, since the outer covering material 1 is made of a synthetic polymer material and the fabric is smooth, the outer covering material 1 is easily separated from the outer covering material 2 and remains in the excavation hole (planting hole) 21, and the tree planting 10 is a root winding material excluding the outer covering material 1. I. Tree planting 10 in this state can be directly replanted at a desired place such as a building rooftop.
