Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for introducing trees to a slope.

[0002]

2. Description of the Related Art In order to harmonize the slope with the surrounding landscape, stabilize the slope permanently, and restore to the natural world, it is preferable to green the slope with trees. A method of introducing a seedling (so-called pot seedling) in which tree seeds are germinated and grown in a pot and a tree for planting a seedling are employed.

[0003]

However, transplanting pot seedlings and seedlings to the slopes tends to cause poor rooting of potted seedlings and seedlings because the growth environment conditions greatly change from before. There was a problem on growth.

[0004] In addition, in order to obtain potted seedlings and seedlings, a dedicated and wide cultivation area is required, and it is necessary to take time and effort to preserve the seedlings before transplanting. Therefore, in addition to being easily restricted by the amount of transportation by vehicle, even if the seedlings and pot seedlings are heavy, they must be handled carefully and in addition, it is extremely difficult to bring them to the slopes and it is hard work. There was a problem in terms of workability.

[0005] In this regard, if tree seeds are directly sown on the slope, the above disadvantages do not occur.
It is not an exaggeration to say that it is impossible to visually check the sowing situation.Therefore, it is inevitable that the seeding will be uneven and the forestation will be uneven. If formed, the seeds will still be washed away by rainfall or frost heaving, and even if they germinate, they will die in the early stages of their growth, or the seedlings will be planted around. In addition, it was hoped that the trees would grow sparsely, instead of becoming trees.

[0006] The present invention has been made in view of such circumstances, and focuses on the fact that the mode of tree introduction by sowing is significantly more advantageous than planting of potted seedlings and seedlings. A seed pot suitable for taking such a form, that is, an unbiased sowing is achieved because the sowing situation can be visually confirmed,
In addition, a tree introduction method that ensures that tree seeds do not run off, that they are not pressed by the surrounding plants, and that enable young plants to grow smoothly even under strong sunlight It is intended to provide.

[0007]

The method for introducing trees to the slope according to the present invention, which has achieved the above object, is a method of corroding with time to homogenize with soil or weaken corrosive materials. It is characterized in that after the driving of the tubular body, the tree seeds are inserted into the tubular body at the inner tip side of the tubular body, and the tree seeds are securely installed at predetermined intervals on the slope. . That is, tree seeds are mixed with soil, organic materials, fertilizers, etc. and installed in a tubular body, or tree seeds are layered with soil, organic materials, fertilizers, etc., and seeds are soil, organic materials, fertilizers, etc. It is installed on the lower side, or a part of these is installed as a soil cover layer for seeds. Further, tree seeds are carried in a bag made of a corrosive material, and this bag holds one or more organic materials, fertilizers, plant fibers, water retention agents, soil conditioners, and tree seeds, and a tree seed. Installed in the shape. In the case of the tubular body, a tubular body with a cap, which is provided with a cap for protecting the end portion in a removable manner, is used at the rear end portion of the driving, or an opening for coloring is provided on the peripheral surface portion of the tubular body. To form.

[0008]

According to the above-mentioned characteristic structure, a cylindrical body made of a corrosive material is driven into a slope at a predetermined position on the slope so as to leave an upper side of the cylindrical body. Tree seeds are inserted into the body, and the tree seeds are placed on the tip side inside the cylindrical body so as to be in close contact with the slope. Thus, by visually observing the location where the cylindrical body is driven, the seeding status of the tree seeds can be accurately grasped, and uniform seeding without bias is achieved.

[0009] The tubular body made of a corrosive material, the tree seed carrier, and the like are lighter than pot seedlings and seedlings, and the tree seeds are held on the carrier. There is no problem even if it is handled a little rough and it is not bulky, so it is excellent in workability as well as workability of transporting and bringing it to the slope, and after driving the tubular body,
When a seed carrier or the like is inserted into the cylindrical body and pressure is applied, the seeds adhere to the soil on the slope surface in the cylindrical body, so that the tree seeds start germinating activity, and the roots of the tree seeds during germination are germinated. The survival property is also excellent.

Further, by installing the seed carrier or the like as described above, the seeds installed on the slope are surrounded by the cylindrical body, so that the tree seeds are prevented from running away due to rainfall or freezing. At the same time, since strong sunlight is blocked by the tubular body, favorable conditions for germination and growth of tree seeds can be obtained, and pressure from surrounding plants can be effectively prevented.

In addition, since the tubular body is eventually corroded, collapsed, or weakened, the root of the tree is not prevented from invading the ground. Because it is homogenized or weakened with soil, there is no inhibition of tree growth by the tubular body, and it is possible to avoid pollution problems such as the tubular body remaining semipermanently on the slope, and good growth conditions. In addition to this, by achieving unbiased sowing, treeing of slopes for greening can be achieved uniformly.

The above-described method for introducing trees according to the present invention is preferably used for cutting slopes, embankment slopes of soil of good quality, surface slopes for spraying soil, backfill soil of fences, and existing plant growth slopes. However, soil, organic material, fertilizer, etc. are mixed with the above-mentioned tree seeds in consideration of obtaining a fertile nursery bed regardless of these slopes or target slopes such as thin land. For example, it is preferable to store them in a tubular body or to store one or more of organic compost, chemical fertilizer, plant fiber, water retention agent, and soil conditioner in the tree seed carrier.

[0013] Also, at the rear end of the driving of each cylindrical body,
If the cap for end protection is provided detachably,
Alternatively, a protective cap is detachably provided on one of the tubular bodies, and the protective cap is diverted, or a protective cap is prepared as an attachment for driving the tubular body. The cylindrical body can be driven without difficulty without causing damage. Furthermore, it is desirable to form an opening in the exposed portion from the slope of the tubular body in order to provide appropriate coloring inside the tubular body and also for drainage.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. In the examples described here, those using the seed carrier shown in claim 4 will be mainly described. FIG.
A indicates a tubular body for introducing trees to the slope, which is a corrosive material that corrodes with time and becomes homogenous with the soil, or weakens (for example, bamboo cylinder, thick corrugated cardboard, and decomposed corrosive plastic). The cylindrical body 2 is made of a material such as an opening a for chromatic light is formed on the peripheral surface of the cylindrical body 2, or the driving tip of the cylindrical body 2 is obliquely cut. B of FIG. 1 is a carrier 3 of the tree seed b.

Specifically, the above-mentioned tree seed carrier 3 comprises:
At least one of soil, organic compost, chemical fertilizer, plant fiber, water retention agent, soil improver and tree seed b are mixed in a bag made of, for example, a water-soluble sheet that corrodes with time and becomes homogenous with soil. The vegetation base material 4 is housed, and the support body 3 is loaded into the front surface of the tubular body 2 after the support body 3 is driven onto the slope of the tubular body 2 so that the support body 3 is placed in the tubular body 2. I try to keep it inside.

The tree seeds b accommodated in the carrier 3 are susceptible to pressure from surrounding plants, in addition to Yamahagi, Itachihagi and Komatsunagi, which are not easily affected by pressure from surrounding plants. Arbor, yashabushi, kunugi, red pine, sharinbai, arakashi, etc. are arbitrarily selected.

FIG. 2 is an enlarged sectional view showing the method of introducing trees according to the present invention on a slope. As shown in FIG. 2, the cylindrical body is driven into the slope surface (slope surface or the surface of the thick layer of soil sprayed on the slope surface), and then the tree seed carrier is inserted. ing.

The above-mentioned cylindrical body 2 has a height of about 5 to 20 cm and a diameter of about 2 to 10 cm. However, the present invention is not limited to this.
Thick ones are preferable from the viewpoint of ensuring sufficient driving strength. In addition, as an opening a for lighting, this has a diameter of 1
Although it has a small diameter hole of about 2 cm and is diffused in the peripheral surface portion of the cylindrical body 2, this opening a can be changed to a slit shape which is long in the axial direction of the cylindrical body 2 or the like, and preferably a predetermined implantation It is also possible to allow the opening a to have a drainage function by allowing the opening a to exist near the slope in this state.

The method for introducing trees to the slope according to the present invention is as follows.
It is suitable for use on cut slopes, embankment slopes, sloping slopes, backfilling of fences, existing plant growth slopes, etc. of high quality soil. The fertile seedbed is obtained by accommodating a vegetation base 4 made of at least one of a chemical fertilizer, a vegetable fiber, a water retention agent, and a soil improvement material. Can be.

For example, a method of greening a slope by introducing trees for the slope spraying method will be described. First, as shown in FIG. 3, a spraying machine such as a mortar gun machine or an aero seeder sprays the slope on the slope 6. A thick layer of soil 8 is sprayed onto the stretched net 7 and, if necessary, drawn in the ground direction and the contour direction so as to form a grid having a gap size suitable for growing trees. Mark.

As shown in FIG. 4A, the cylindrical body 2 is positioned at the seeding point of the tree-lined seed, and the intersection of the marks of the grid-like drawing is used as the seeding place of the tree seed b. 4
As shown in (B), the tubular body 2 is driven into the soil spraying slope 9 so that the upper side of the tubular body 2 is left.
After the cylindrical body 2 is driven in, the carrier 3 of the tree seed b is inserted into the front end side of the cylindrical body 2, and the soil is sprayed on the slope 9.
Install so that it adheres tightly. Eventually, as shown in FIG. 4C, the tree seed b germinates and grows.

Further, as shown in FIG. 4, when the cylindrical body 2 is driven into the slope, the rear end portion of the cylindrical body 2 is protected so that the rear end portion of the cylindrical body 2 can be protected. It is preferable that a protective cap 5 made of, for example, a metal is detachably provided, and in the illustrated example, the protective cap 5 has a lid shape that closes the trailing end side of the tubular body 2 that is driven in, to protect the protective cap 5. Although the entire surface can be the driving surface of the tubular body, it may be a ring shape having a U-shaped cross section for protecting only the driving end edge of the tubular body 2. Cylindrical body 2
At the time of driving, by providing the protective cap 5 at the end of the cylindrical body 2 after the driving, the cylindrical body 2 can be driven without difficulty without damaging the end, and the driving is performed. When finished, cover-shaped protective cap 5
The protective cap 5 must be removed because it interferes with the growth of the tree seeds b, and because the protective cap 5 is permanently left on the slope, leading to pollution problems.

Since the detached protective cap 5 can be diverted to another tubular body 2, it is not necessary to provide the protective cap 5 on all of the tubular bodies 2, If a protective cap is prepared as an attachment for driving the body 2, the protective cap 5
There is no need to provide.

As described above, according to the present invention, the seeding state of the tree seeds b can be accurately grasped by inserting the cylindrical body 2 into the intersection point drawn in a grid and inserting the tree seed carrier. , Or even without marking
By visually observing the location where the cylindrical body 2 is driven into the slope 9 for spraying the soil, the seeding status of the tree seeds b can be accurately grasped, so that uniform seeding of the tree seeds b is easily achieved.

Then, the cylindrical body 2 and the seed carrier 3
Is light and not bulky, so it can be transported and sloped 9
In addition to the workability of bringing the seeds into the soil, the seeds carrier 3 is in close contact with the soil spraying slope 9 so that the root vigor of the tree seeds b at the time of germination is also excellent. .

Also, since the cylindrical portion 2 surrounds the seed carrier 3 installed on the slope 9 for spraying soil, rain of the tree seeds b as well as the vegetation base material 4 due to rainfall and frost heave are effective. Is prevented. Then, while appropriately taking in light through the upper opening of the cylindrical body 2 and the opening a of the peripheral surface portion, since the cylindrical body 2 blocks strong sunlight,
Furthermore, by draining excess rainwater from the opening a in the peripheral surface or the bottom of the tubular body, favorable conditions for germination and growth of the tree seed b can be obtained, and pressure from surrounding plants is applied. This is also effectively prevented by the tubular body 2.

Moreover, since the tubular body 2 will eventually corrode and collapse, it will not hinder the intrusion of the roots of the tree into the ground and the growth of the tree, and the tubular body 2 will be the final product. Since the soil is homogenized with the soil, pollution problems can be avoided, and in addition to good growth conditions, evenly-seeded seedlings are achieved, which results in a uniform slope 6 for greening. It is possible to achieve abundant forestation.

As a manner of holding the carrier 3 with respect to the inner tip side of the tubular body 2, the carrier 3 is inserted loosely into the inner tip side of the tubular body 2 so that the inner diameter of the tubular body 2 is small. By using a rod-shaped body having a smaller diameter and the like, the carrier 3 is pressed after it is inserted, and the carrier 3 is brought into close contact with and stabilized on the sloped soil surface or the thick soil surface of the cylindrical body. Germination activity is started.

Although an example in which the tree seeds b are mixed with the vegetation base material 4 and housed in the bag-shaped carrier 3 has been mainly described, the sheet-shaped carrier 3 is coated with, for example, a water-soluble glue. The tree seed b is adhered by the agent, and the sheet-shaped tree seed carrier 3 is driven into the tubular body 2 and then inserted into the tubular body, and then one or more of soil, organic material, fertilizer and the like. May be put in the tubular body 2 to cover the tree seeds with soil,
Conversely, the sheet-like tree seed carrier can be inserted after the soil or the like is first introduced, and can be brought into close contact with the surface of the soil or the like.

In the above examples, the bag-shaped and sheet-shaped seed carriers are used for the tree seeds. However, the use of the seed carriers ensures reliable and easy quality control on site. There is a unique effect such as excellent workability. The present invention is not limited to the use of the above-mentioned seed carrier, tree seeds, soil, organic material, or installed in a tubular body mixed with fertilizer, tree seeds, soil, organic material, It can be carried out by various methods such as the seeds are soil, organic materials, the lower side of the fertilizers, etc., or a part of them is installed as a soil cover layer for the seeds, according to the fertilizer etc. , Construction area,
It is appropriately adopted depending on the height of the slope and the like.

[0031]

As described above, according to the method for introducing trees according to the present invention, by applying the method to the slope, the tree seeds can be placed on the slope so that the roots of the tree seeds are suitable for the roots. Since the seeds can be installed so as to be in close contact with each other, and the seeding status of the tree seeds can be accurately grasped visually, uniform seeding of the tree seeds can be achieved.

Since the material used for the cylindrical body and the like is lightweight and not bulky, it is excellent in handling and workability. In addition, since the seeds and the like set on the slope are surrounded by the cylindrical body. The favorable conditions for germination and growth of the tree seeds are obtained because the runoff of the tree seeds due to rainfall and frost heave is effectively prevented, and the strong sunlight is blocked.
Further, pressure from surrounding plants is effectively prevented.

Further, since the cylindrical body is corroded and collapsed, the growth of the tree is not hindered, and the pollution problem can be avoided. By achieving no seeding, the forestation of the slope for greening is achieved uniformly.
