DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting method.

[0002]

2. Description of the Related Art In recent years, emphasis has been placed on the preservation of the natural environment and the maintenance of landscapes due to greening, and in various civil engineering works such as residential land development, road maintenance, river projects, etc., planting in parallel with the construction. There is a demand for promoting greening. For example, in river projects, plants such as willows are planted on seawalls laid with stone baskets, such as gabions, to not only consolidate seawalls and preserve landscapes, but also purify water, maintain ecosystems, and maintain microorganisms. It has been required to create an environment for growing plants, insects, fish, and the like.

[0003] However, it is very difficult to plant a plant at the place where the stone basket is laid as described above, and the plant cannot be planted because the stone is in the way. In many cases, the plants moved and hurt the plants, and the stones hindered the growth of the plants and hindered their growth. Therefore, it was necessary to take some measures for planting.

On the other hand, as shown in FIG.
In order to plant the plant on the seawall hardened by the above, a hole 2 for planting is drilled in the concrete 1, and a pipe 3 made of vinyl chloride is erected in the center of the hole 2 filled with stone, and a willow is inserted in the pipe 3. An example of planting a plant 4 such as this has been known, and it is possible to exhibit the effect of protecting and growing the plant to some extent after planting.

However, the pipe 3 made of vinyl chloride completely envelops the root portion of the trunk, so that after the plant has grown to some extent, it hinders the growth and inhibits the elongation of the branch root. Had an adverse effect on plant growth.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to secure planted plants safely even in places where planting is difficult such as places where stone baskets are laid or seawalls hardened with concrete. Another object of the present invention is to provide a planting method that can reliably protect and grow.

[0007]

In order to solve the above-mentioned problems, a planting method according to the present invention is characterized in that a planting protection frame formed into a net tube shape by a filament is placed between stones filled in a stone basket. Standing , planting a plant in the protection frame, growing the planted plant while protecting the plant with the protection frame, and embedding the protection frame in the bark in the process of growing the plant. Is what you do. The plants planted in the protection frame gradually grow while being protected by the protection frame. At this time, since the protective frame has a net tubular shape and excels in water permeability and air permeability and does not inhibit the elongation of the branch root, the protective frame does not adversely affect the growth of the plant.
When a plant grows and its trunk becomes thicker than the protective frame, the protective frame gradually becomes wrapped in the bark in the process, and is eventually completely contained. In the present invention,
A corrugated protective frame can be used.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the planting method of the present invention will be described below in detail with reference to the drawings. 1 and 2 show an example of a protective frame used in the method of the present invention.
0 is formed in a net tube shape by connecting a plurality of vertical lines 11 positioned so as to surround the axis at appropriate intervals by a plurality of ring-shaped horizontal lines 12 positioned vertically at appropriate intervals. . The diameter (thickness) and length of the protective frame 10 are
As shown in FIG. 3, the optimum setting is made according to the type of the plant 14 to be planted therein, the size (height) of the stone basket 17 and the situation at the site.

The lower end of the vertical line 11 is bent toward the outside of the cylinder to form a retaining portion 15. This retaining portion 15
When the protection frame 10 is installed, the protection frame 10 is locked to the mesh or the packing stone of the stone stuffing basket 17 to prevent the protection frame 10 from being pulled out.
This retaining portion 15 does not need to be provided on all the vertical lines 11,
It may be provided only on some vertical lines 11. Or horizontal line 1
In the case where 2 is locked and fixed to the filling stone, it is not always necessary to provide such a retaining portion 15.

As shown in FIGS. 3 and 4, the protective frame 10 having the above-described structure is used when laying the stone basket 17 in the revetment work or the like. Is erected so as to penetrate the mesh 17a, and the stones 18 are packed in the basket 17 in this state, so that the surroundings of the
It is installed in a state where it is supported. In this case, it is preferable that the height of the protection frame 10 and the height of the basket 17 are substantially the same. When the diameter of the protective frame 10 is larger than the mesh 17a of the basket 17, the column lines 17b constituting the basket 17 may be appropriately cut to widen the mesh. It is needless to say that the end of the cut column line 17b is entangled with a nearby column line so as not to be unraveled.

The work for filling stones in the basket 17 may be carried out either by mechanical packing or manual packing, and the basket 17 may or may not have an upper surface net.

When there is a possibility that the protection frame 10 may be crushed or deformed by the impact of the stone when the stone is packed into the stone basket 17, a reinforcing member 19 such as a rod is inserted into the protection frame 10 in advance. By pulling out the stone after the completion of the stone filling, the protection frame 10 can be prevented from being crushed or deformed. In this case, if the retaining portion 15 is formed at the lower end of the vertical line 11, the retaining portion 15 is locked to the row line 17 b of the bottom net of the basket 17, the stuffing stone 18, and the like. The reinforcing member 19 can be pulled out without fail.

Next, the plant 14 is inserted and planted in the protection frame 10 where the installation is completed. In the case of a non-rooted willow or the like, a hole is dug in the ground with a stick and the water level is taken into consideration. It is effective to plant deeply. The area around the plant is filled with water-retaining soil or water-retaining agent, if necessary.
If the space between 0 and 0 is large, the plant is supported and fixed by filling it with organic matter such as old wood chips that decay and rot in several years.

The plant 1 thus planted in the protective frame 10
4 grows gradually while being protected from the clogging by the protective frame 10, but the protective frame 10 has a net tubular shape, has excellent water permeability and air permeability, and has an extension of the branch root. And does not adversely affect plant growth.

When the plant 14 grows and its trunk becomes thicker than the protection frame 10, the protection frame 10
Each of the vertical lines 11 and the horizontal lines 12 is first wrapped in the tree meat and finally completely included. Therefore, plant 14
It is not necessary to remove the protective frame 10 in accordance with the growth of.

In the protective frame 10, the shape of the ring of the horizontal line 12 does not need to be circular, but may be any other shape, for example, an elliptical shape or a rectangular shape such as a polygon. In addition, the protective frame 10 does not need to have a uniform thickness over its entire length, and may be thinner at the bottom, may be thinner at the top, or may have a partially different thickness at the middle part. May be.

FIGS. 5 and 6 show another example of a protective frame used in the method of the present invention. The protection frame 20 is different from the above-described protection frame 10 in that a vertical line 21 and a horizontal line 22 are corrugated. In the case of the vertical line 21, the vertical line 21 and the central axis of the protection frame 20 are used. Are bent by bending the vertical line in a plane including
2 is corrugated by bending the horizontal line in the plane including the ring.

The corrugation is effective when a plant planted in the protective frame 20 grows and becomes thicker than the protective frame 20. That is, when the trunk of the plant becomes thicker than the protection frame 20, the vertical line 21 and the horizontal line 22 of the protection frame 20 in the process.
Is gradually wrapped in the bark, and is eventually completely contained. At this time, the penetration of each line 21 and 22 into the trunk by the waveform partially and temporally progresses, and the entire line At the same time, the occurrence of continuous necking due to biting into the stem is prevented, and the strength of the stem is prevented from lowering due to the necking. In particular, when the ring-shaped horizontal line is a circular shape that is not corrugated, if it penetrates into the trunk at the same time on the entire circumference, a continuous circumferential constriction is formed in the trunk, and the There is a possibility that the strength of the trunk will decrease at the constricted part.
By corrugating the horizontal line 22 like 0, the occurrence of such a continuous circular constriction can be prevented.
In this case, it is not always necessary to corrugate both the vertical line 21 and the horizontal line 22, and it is sufficient if at least the horizontal line 22 is corrugated.

In each of the above protective frames, the vertical line may be disposed inside or outside the ring in the horizontal line, or may be disposed separately on both the inside and outside of the ring as shown in FIG. Can also. Also, the vertical and horizontal lines can be knitted like a crimped wire mesh, in which case the vertical and horizontal lines need not be welded to each other.

[0020]

As described above in detail, according to the planting method of the present invention, a planting protection frame formed in a net shape by a filament is used, and a plant planted inside the planting protection frame is used as the protection frame. The plant is protected and protected by the protective frame, so even in places where slogging baskets are laid or where concrete is hard to plant, such as seawalls hardened with concrete, plants can be safely and securely protected by the protective frame. In addition, since the above-mentioned protective frame is formed by the streaks and is buried in the bark as it is during the growth of the plant, the protective frame is removed after the growth of the plant. There is an advantage that there is no necessity, management is easy, and no trouble is required.
