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 tree seedlings into a slope such as a slope, a vegetation pot for tree seedlings used in the method, and a tool for introducing tree seedlings into a slope. It is.

[0002]

2. Description of the Related Art For example, in order to achieve harmony with the surrounding landscape of the slope, early and permanent stabilization, and restoration to the natural world, tree seedlings are planted on the slope to turn the slope into a forest. Greening is preferred.

[0003] When the slope is made into a forest, a cylinder for holding the floor soil, the lower end of which is formed on the slope, is installed on the slope of the slope, and the seeds of the tree are germinated and buried in a pot made of vinyl or the like.
A so-called pot seedling that has been grown is prepared, a tree seedling is taken out of the pot, and the tree seedling is transplanted into a cylinder.

[0004]

When the tree seedlings are taken out of the pot when carrying out this method of introducing trees, the bed soil of the seedlings is liable to collapse. In addition, it is necessary to separately replenish the cylinder with floor soil in order to raise the tree seedling to a natural posture.

[0005] However, the work of removing the tree seedlings from the pot and the step of separately raising the tree seedlings into a natural posture while replenishing the soil with the cylinder are extremely troublesome.
Furthermore, it took a great deal of effort and time to perform this cumbersome operation over a wide range of slopes.

[0006] In addition, the bed soil replenished in the cylinder rapidly changes the environmental conditions for the growth of the tree seedlings, which may cause poor rooting of the tree seedlings. There was a problem in that costs were required for cleaning the pot.

[0007] The present invention has been made in view of such circumstances, and its purpose is to perform this operation in a short time, easily and easily even when introducing trees over a wide area.
The present invention provides a method for introducing tree seedlings, which does not require disposal after the pot, and which is excellent in terms of vitality, a vegetation pot for tree seedlings suitable for use in this method, and an auxiliary tool for introducing tree seedlings to an inclined surface. On the point.

[0008]

According to the first aspect of the present invention, a method for introducing tree seedlings into an inclined surface is a method of forming a floor soil holding cylinder made of a corrosive material having a lower end formed on an inclined portion. On the other hand, the soil is stored in a pot made of a corrosive film having a root extension hole formed in the sloped bottom surface, and a tree seedling is vegetated on the storage floor soil. It is characterized in that the seedling vegetation pot is housed in a cylinder installed on the inclined surface.

In the method for introducing tree seedlings into the inclined surface according to the second aspect of the present invention, the floor soil is accommodated in a pot made of a corrosive film having a root extension hole formed in the inclined bottom.
In addition, tree seedlings are vegetated on the storage floor soil, and a vegetation pot of the tree seedlings is held in a floor soil holding cylinder made of a corrosive material having a lower end portion formed on an inclined portion, and the cylindrical body is removed. It is characterized in that it is installed on an inclined surface such as a slope.

[0010] In vegetation of tree seedlings, as an example, a floor soil storage pot is formed such that the inclined bottom surface portion is approximated to the inclined surface portion into which the tree seedling is introduced. The seedlings are placed on the seedling base or transplanted with seedlings of the tree after or before the placement of the pot and the seedlings are placed on the seedling base with the central axis of the pot oriented vertically. Tree seedlings can be vegetated on the floor soil.

According to the first aspect of the present invention, the tubular body for holding the floor soil is formed such that the center axis of the tubular body is oriented in the vertical direction, and the inclined portion at the lower end is along the inclined surface. The vegetation pot is set in a predetermined position on a slope such as a slope, and the vegetation pot for the tree seedlings is accommodated in the cylinder so that the sloped bottom portion thereof is along the slope. In the case of a configuration that is loosely housed in a cylindrical body, the introduction of tree seedlings to the slope can be completed easily by replenishing the floor soil so as to fill around the vegetation pot .

According to the second aspect of the present invention, the vegetation pot is housed in the cylinder while the inclined bottom surface of the vegetation pot is aligned with the inclined portion of the lower end of the cylinder, and the vegetation pot is held. By installing the cylinder at a predetermined position on an inclined surface such as a slope, the center axis of the cylinder is oriented vertically, and the inclined portion at the lower end is made to follow the inclined surface. It is possible to easily complete the introduction of the tree seedling to the slope.

In any of the above-mentioned construction methods, the vegetation pot is housed in a cylindrical body while the tree seedlings are kept vegetated, so that the floor soil does not fall down. Replenishment does not change the conventional growth environment conditions of the tree seedlings.

Further, since the bottom surface of the floor soil storage pot is inclined, the inclined bottom surface can be brought into close contact over a wide area of the inclined surface.
Depending on the inclination angle of the inclined surface such as the slope, there is a concern that a gap may be formed between the inclined surface and the inclined bottom, but since the pot is made of a film and is easily deformed, the vegetation pot is used. By gently pushing the inclined bottom into the cylinder, the inclined bottom surface can be brought into close contact with the inclined surface.

As described above, the roots of the tree seedlings are extended through the holes formed in the inclined bottom surface portion so that the inclined bottom surface portion of the vegetation pot is brought into close contact with the inclined surface portion over a wide area, so that the roots of the tree seedlings extend to the inclined surface portion such as the slope surface. The roots will be rooted so as to spread in a fan shape, and in addition, since the pot appropriately retains moisture, the tree seedlings will be satisfactorily settled on the slope without summer withering.

Further, since the cylindrical body surrounds the vegetation pot, it is possible to effectively prevent runoff of the floor soil in the pot due to rainfall, and furthermore, the cylindrical body blocks strong sunlight. Therefore, favorable conditions for the growth of tree seedlings can be obtained, and since the tree seedlings are isolated from the herbaceous plants growing around by the cylinder, pressure from the herbaceous plants can be effectively prevented. It is.

Moreover, since the tree seedlings are housed in the cylinder with the pot attached, it is not necessary to dispose of the conventional pot, and the pot and the cylinder eventually corrode, Since it is homogenized as soil, it does not involve any pollution problem. Therefore, according to the method of the present invention, even if trees are introduced over a wide area,
This work can be done easily and easily in a short time, and there is no need to clean up the pot.Furthermore, the growth conditions are good, and the introduction of tree seedlings that are excellent in terms of vigor is able to achieve a natural tree planting systematically. Is done.

According to the fourth aspect of the present invention, there is provided a floor soil storage pot made of a corrosive film having a root extension hole formed on an inclined bottom surface, and a tree seedling planted on the floor soil stored in the pot. Thus, a vegetation pot for tree seedlings suitable for use in the method for introducing tree seedlings is provided. At this time, as described in claim 5, the floor soil storage pot is provided with a sloped bottom portion thereof. It is desirable to approximate the slope to which the tree seedling is to be introduced.

According to the sixth aspect of the present invention, the plant seedling necessary for performing the tree seedling introduction method according to the vegetation pot according to the fourth aspect and the cylindrical body accommodating the same. Introductory aids are provided.

[0020]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an auxiliary tool A for introducing a tree seedling a into an inclined surface portion N such as a slope (see FIGS. 3 and 4; hereinafter, referred to as a slope).

FIGS. 3 and 4 show an embodiment of a method of introducing tree seedlings a to the slope N. More specifically, the slope N is made into a forest by coexisting with herbaceous plants. This shows the initial state of greening of the greening method.

FIGS. 1 and 2 show an auxiliary tool A for introducing a tree seedling a.
As shown in FIG. 1, a circular cylindrical body made of a corrosive material (in this embodiment, a bamboo cylinder is used, but other pipes such as biodegradable plastics can be used).
And a vegetation pot 2 of tree seedlings a housed in the cylinder 1 in a very close state, and with the central axis of the cylinder 1 oriented vertically. Lower end 1a
Is formed at an angle approximating the inclination angle of the slope N on which the tree seedling is to be introduced.

On the other hand, the vegetation pot 2 is a bottomed floor soil storage pot 3 made of, for example, a corrosive film mainly composed of starch, which decomposes in one to two years, and is vegetated on the floor soil 4 stored in the pot 3. The above-mentioned cylindrical body 1 has a floor support 4 in a pot 3 accommodated in the cylindrical body 1 for a long time with the introduction aid A installed on the slope N. The shape is to be retained and held over.

The bottom surface of the bottomed pot 3 is adjusted so as to match the inclined portion 1a at the lower end of the cylindrical body, that is, to approximate the inclination angle of the slope N on which the tree seedling is to be introduced. In addition to being formed in the portion 3a, the inclined bottom portion 3a has
An extension hole b of the root of the tree seedling a is formed, and a drainage hole c is formed at the lowermost end of the inclined bottom surface 3a.

FIG. 5 shows a seedling raising base 5 for obtaining a vegetation pot 2 of a tree seedling a. The seedling raising base 5 is made of, for example, a synthetic resin. The case main body 6 has a large number of circular recesses 7 for accommodating the floor soil storage pots 3 from above in a substantially close state. And the bottom portion of the concave portion 7 is formed on an inclined bottom portion 7a in accordance with the inclined bottom portion 3a of the floor soil storage pot 3, and the lowermost end portion and lower portion of the inclined bottom portion 7a are formed. Face plate 6a
And a drain hole d is formed.

Then, as is clear from FIG.
With the pot 3 housed in the recess 7, the depth of the recess 7 is made slightly smaller than the height of the pot 3 so that the upper edge of the pot 3 projects slightly above the case body 6, Recess 7
It is configured so that the pot 3 can be easily taken out from the container.

At the time of vegetation of the tree seedlings a using the seedling raising base 5, first, if necessary, the seedling raising base 5 is brought into, for example, a vinyl house, and the floor soil storage pot 3 is placed in the recess 7 of the seedling raising base 5. On the other hand, as the floor soil 4, for example, organic compost, chemical fertilizer, vegetable fiber, water retention agent,
A vegetation base material containing a soil improving material and the like is prepared, and the vegetation base material is accommodated in the pot 3 and the seeds a ₁
Or a seedling a _{2 of} a tree germinated and grown on a nursery or the like in another place is taken out from the pot 3a, and transplanted to the floor soil 4 in the pot to grow the tree seedling a. is there.

In FIG. 6, (A) shows a state in which tree seeds a ₁ are sown on the floor soil 4 stored in the pot 3, and shows a state in which tree seedlings a ₂ are transplanted on the floor soil 4. This is shown in FIG. Then, seed a ₁ is germinated and grown steadily, for the seedlings a _2, which indicates to grow steadily, trees seedlings a which grew enough waiting for introduction into slope N in (C) .

As the tree seedling a, there are arbitrarily selected, for example, oak, sharinbai, arakashi, mud mochi, keaki, Japanese red pine, Japanese black pine, rowan, etc. Since the seedling a is hardly subject to pressure, seedlings of ground cover plants such as ivy and hedera may be mixed.

Slope N by forestation coexisting with herbaceous plants
At the time of greening, first, while the vegetation pot 2 in which the tree seedlings a are vegetated is accommodated in the seedling raising base 5, the required amount of the seedling raising base 5 is carried into the greening work area, while the slope to be greened is N is appropriately shaped.

Then, as shown in FIGS. 3 and 4, on the slope N, string-like members 8 made of vegetable fiber, for example, made of plant fiber having water retention and corrosiveness are arranged lengthwise and crosswise. A mat 9 impregnated with a herbicide is dispersed and arranged on the slope N so as to cross the state body 8.

The mat 9 is made of vegetable fiber such as jute or coco, which has water retention and corrosiveness, and has an opening 10 facing the cord 8 at the center. For example, fatty acid-based herbicides (eg, Frenock;
(Trade name of Sankyo Co., Ltd.).

Next, for example, the mesh size is 50 mm × 50 mm
A metal net 11 such as a wire net is stretched on the slope N using the anchor 12 so as to press the string-like body 8 and the mat 9, and the tree seedling a is introduced. A pot 2 in which a tube 1 and a tree seedling a are vegetated, which constitutes the auxiliary tool A, is prepared, and the inclined portion 1a of the tube 1 is prepared.
Is arranged on the net 11 in a state of being aligned with the opening 10 of the mat 9.

Then, the tree seedling a with the pot 3, that is, the vegetation pot 2 is housed in the above-mentioned cylinder 1 from above with the pot still attached, and a peg 13 is inserted into a hole previously drilled in the cylinder 1. Into the slope N, and another peg 13 is applied to the upper end of the cylindrical body 1 so that the peg 13 is driven into the slope N, so that the cylindrical body 1 and thus the tree seedling a This is to prevent the introduction assisting tool A from falling down.

At this time, the inclined portion 1a at the lower end of the cylindrical body is formed so as to approximate the inclined angle of the slope N on which the tree seedling is to be introduced.
If the installation posture of the tree body is greatly inclined to the oblique posture, which is inconvenient for growing the tree seedling a in a natural standing posture, in addition to the driving of the peg 13, the upper end of the cylindrical body 1 It is only necessary to strike and beat the lower end portion of the cylindrical body 1 to perform the posture correction work of embedding the lower end portion into the slope N so that the central axis of the cylindrical body 1 is directed vertically.

The opening 10 of the mat 9 is formed to be about the size of the vegetation pot 2, but may be smaller or slightly larger than this. It is not necessary to open ten.

In the above embodiment, the vegetation pot 2 for the tree seedlings a is housed in the cylinder 1 in a very close state. The vegetation pot 2 is formed to be slender, and the vegetation pot 2 is loosely accommodated in the cylindrical body 1.
a may be supplemented.

In addition, the procedure of arranging the vegetation pot 2 in the tubular body 1 after arranging the tubular body 1 on the net 11 is adopted. Unitize the introduction aid A for seedling a
It is possible to arrange the cylinder 1 on 1 and appropriately use the peg 13 to prevent the introduction aid A of the cylinder 1 and thus the tree seedling a from falling down. In addition, even if the operation of introducing the tree seedlings a to the slope N is wide-ranging, it can be performed easily and easily in a short time.

After the placement of the introduction aid A for the tree seedling a,
Using a spraying machine such as a mortar gun machine or aero seeder,
A soil containing the herb seed e (for example, the vegetation base material described above) 14
Is sprayed onto the slope N around the introduction aid A for the tree seedlings a, thereby completing the greening of the slope N by introducing the tree seedlings a together with the herbaceous plants.

The herbaceous seeds e to be included in the soil 14 are appropriately selected from grass seeds of short grasses and flower seeds, including grassy vegetation of rice, and white clover is used as the grass seeds. , Creeping red fescue, red top, bermuda grass, Kentucky blue grass and the like are suitably selected.

According to the above-described method for introducing tree seedlings, the tree seedlings a are accommodated in the cylindrical body 1 with the pots attached.
The growth environment conditions of the tree seedlings a so far do not change suddenly, and furthermore, not only is the cleaning of the pot 3 unnecessary, but also the cylindrical body 1 and the pot 3 eventually corrode,
Eventually, the seeds are homogenized with the soil, so that even if the tree seedlings a are arranged with the pot, there is no pollution problem.

Further, since the cylindrical body 1 is provided so as to surround the vegetation pot 2, the runoff of the floor soil in the pot due to rainfall can be effectively prevented.
Since the strong sunlight is blocked by this, favorable conditions for the growth of the tree seedling a can be obtained.

Since the bottom portion 3a of the floor soil storage pot 3 is inclined, the inclined bottom portion 3a is
Can be adhered over a large area of
Depending on the inclination angle of the slope N, the slope N and the inclined bottom surface 3a
There is a concern that a gap may be formed between the vegetation pot 2 and the pot 3 by lightly pushing the vegetation pot 2 into the cylindrical body 1 because the floor soil storage pot 3 is made of a film to facilitate deformation. Can be brought into close contact with the slope N.

As described above, the inclined bottom portion 3 of the vegetation pot 2
a is brought into close contact with the slope N over a wide area, so that the roots of the tree seedlings a pass through the holes b formed in the inclined bottom surface 3a.
Further, it extends through the drain hole d and is rooted on the slope N so as to spread in a fan shape.

[0045] Preferably, with reference to FIG. 6, as to bias the inclined upper side of the face of slope N with respect to the center of the pot 3 trees seedlings a, tree seeds a ₁ sowing position or seedlings a ₂ The transplanting position is specified, and the root of the tree seedling a is taken into consideration from the upper side to the lower side of the inclined bottom surface portion 3a of the pot 3 and to extend widely over the entire surface of the inclined bottom surface portion 3a. Thereby, the root of the tree seedling a is tilted to the inclined bottom portion 3a.
From the holes b and d of FIG.

On the other hand, since the plant fiber mat 9 absorbs water such as rainfall and enhances water retention around the bottom of the vegetation pot 2, the string 8 also absorbs water such as rainfall. Since the water retention and the water retention of the surrounding soil are increased, and furthermore, the floor soil storage pot 3 appropriately retains moisture, the tree seedlings a can withstand the surrounding dryness and do not die in the summer, and are good. Will grow.

The roots of the tree seedlings a extend through the opening 10 of the mat 9 in order to absorb nutrients and moisture from much of the soil surface of the slope N in order to absorb nutrients and moisture. However, the supporting roots of the horizontal root system, which are important in supporting the tree body, also extend so as to be rooted along the ground (see FIG. 8).

On the other hand, the herbaceous seeds e in the soil 14 sprayed on the surrounding area E of the vegetation pot 2 include the weeds impregnated in the plant fiber mat 9 including the weed seeds flying here. Because the agent suppresses the growth even if it germinates, in addition to this, the tree seedling a is isolated from the herbaceous plants growing around by the cylinder 1,
The tree seedling a grows without being pressed by the herbaceous plant (see FIGS. 7 and 8), and the herbaceous seed e also grows except for the pot surrounding area E.
Is no longer subjected to pressure by the herbaceous plant b, and the tree species of the tree seedling a to be introduced is not questioned.

Therefore, if a tree seedling of a native species is selected as the tree seedling a, for example, excellent coexistence of the native species tree and herbaceous plants will result in excellent greening of the slope N suitable for the area due to forestation. It is achieved.

The above-mentioned mat 9 is intended to enhance water retention around the vegetation pot 2, and it is not essential to impregnate the mat 9 with a herbicide. 9 may be omitted.

Although the net 11 is made of a metal such as a wire net, the net 11 may be replaced with a synthetic resin or a corrosive vegetable fiber. Since this net 11 eventually corrodes and is finally homogenized with the soil, it is suitable for solving the pollution problem.

In the above embodiment, the soil 14 including the herbaceous seeds e is sprayed after the tree seedlings a are introduced, and the soil 14 is sprayed on the tree seedlings a. If it is concerned that the auxiliary tool A will obstruct the spraying of the soil 14 by the hose, the net 1
After laying 1, spray the soil 14 and then
What is necessary is just to take the form which arrange | positions the introduction auxiliary tool A of the tree seedling a.

Further, if the greening of the slope N does not require coexistence with herbaceous plants, for example, a net 11 is stretched on the slope N, and an introduction aid A for introducing the tree seedling a is placed thereon. Without installing or stretching the net 11, simply install the tree-plant seedling a introduction aid A on the slope N
It is also possible to make the slope N into a forest by simply introducing
