DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pot seedling for slope planting and a construction method for greening by placing the seedling on a flat slope.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a pot seedling b having an inverted truncated cone-shaped root pot a as shown in FIG. As a method of planting, a potted seedling b is placed directly on a flat slope c, and then a vegetation base material (mixture of soil, fertilizer, etc.) d is sprayed, and a hole for planting on the slope c. (Not shown)
A method of planting a pot seedling b in the hole is known.

[0003]

Problems to be Solved by the Invention The conventional planting technique described above has the following problems.

<A> In the former method, the root pot a of the potted seedling b or the seedling is tall, so that the stability is poor. Furthermore, since the height of the potted seedlings b is often higher than the sprayed thickness of the vegetation base material d, only the planting site must be sprayed thickly, and the loss of the vegetation base material d is large.

[0005] <b> In the latter method, water accumulates in the holes, the roots of the potted seedlings b are easily rotted, and there is a concern that the ground may be damaged.

<C> As a problem common to both, the plant is planted with a slope work with little specialized knowledge on plant cultivation, and the plant mortality is high.

<D> As a problem common to both, when spraying the vegetation base material d from the upper side of the slope c to the lower side sequentially,
Potted seedlings b hit the spraying hose, and the seedlings are likely to fall or be damaged.

In addition, the dodging work of the hose for avoiding contact with the potted seedlings b when spraying the vegetation base material d is very troublesome. Further, when the seedlings are growing, the loss due to the spraying construction of the vegetation base material d attaches to the branches and leaves and becomes weak or dies, so that protection by a sheet or the like is required, and a great amount of time and labor is required. .

[0009]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and aims to secure the stability of seedlings during construction and to secure the growth of seedlings. An object of the present invention is to provide a pot seedling for slope planting and a planting method capable of greatly improving workability.

[0010]

Means for Solving the Problems The present invention is a pot seedling for slope planting, wherein the root pot of the seedling is grown thinly and densely without cutting the root system, and the above-ground part is cut off from the middle. Furthermore, the present invention is a pot seedling for slope planting, wherein the entire pot seedling is covered with an anti-transpiration agent. Furthermore, the present invention forms the root pot thinly and grows densely without cutting the root system.
And use pot seedlings with the ground part cut off from the middle
Then, the pot seedling is placed on a slope and covered with a vegetation base material until the root pot of the pot seedling is hidden.

[0011]

Embodiment 1 An embodiment of the present invention will be described below with reference to the drawings.

<A> Potted Seedling As shown in FIG. 1, a potted seedling 10 for slope planting (hereinafter referred to as "potted seedling") is a root pot portion 1 having a thin and dense root system.
The above-mentioned seedlings 12 are cut back before being brought into the site. You.

<B> Root pot section (FIGS. 1 and 2) The root pot section 11 is composed of a root system 13 and an earthen block which are densely grown by thin pots. Generally, the root system 13 of the seedling 12 grows in all directions, but grows faster in the horizontal direction than in the depth direction. Further, it is desirable that the thickness of the root pot portion 11 is set to be almost as thin as the sprayed thickness of the vegetation base material described later.
Therefore, the root system 13 of the seedling 12 easily grows densely over the entire area in the thin pot. Further, the plane shape of the root pot portion 11 can be a circle, a square, or the like, and is not limited to the illustrated shape.

<C> Seedling (FIG. 1) Since the potted seedlings 10 are cultivated in a facility with a suitable growth environment, the above-ground branches and leaves grow as the root system 13 grows. If the plant is transported to the site and planted as it is, the root absorbs less water than the above-ground water requirement due to environmental changes, and the seedlings 12 tend to die. So, before planting, the seedlings 12
The above-ground branches and leaves are cut off and cut back. Sapling 1
The reason for cutting back the branches and leaves of the above-ground part 2 is to secure a balance between the supply and demand of water of the seedlings 12 after planting,
This is for avoiding the problem of fending off the hose when spraying the vegetation base material 50, and for increasing the landscape by growing branches and leaves at a low position. The seedlings 12 are selected from varieties that are less likely to die due to cutback of the above-ground portion and have high sprouting properties.

[0015]

Next, a planting method using pot seedlings will be described.

<A> Installation of pot saplings (FIG. 2) First, the pot saplings 10 are placed on the slope 20 at the construction site.
If necessary, insert the pin 30 into the root pot 11 and fix it.

<B> Spraying of Planting Substrate (FIG. 2) Next, a vegetation substrate 40 is sprayed on the entire surface of the slope 20. At the time of spraying, since the branches and leaves on the top of the potted seedling 10 have been cut and removed in advance, the dosing operation of the spraying hose can be easily performed.
Sprayability is also good. In addition, since the thickness of the soil portion 11 of the potted seedling 10 is small, the sprayed thickness of the vegetation base material 40 can be evenly distributed, there is no partial undulation change, the finish is flat, and the landscape of the slope 20 is not impaired.

<C> Rooting of seedlings In general, seedlings are transferred from the cultivation facility to the slope, and due to changes in the environment, the root absorbs less water than the required water in the above-ground part, and is likely to die. On the other hand, the potted seedling 10 is cut off before planting so that the branches and leaves on the top of the seedling 12 are balanced with the water absorption of the root system 13 after planting. It is fixed on the slope 20 without performing.

[0019]

Embodiment 2 It is conceivable to coat the whole pot seedling 10 with an anti-transpiration agent. As the anti-transpiration agent, paraffin that can be decomposed or melted after planting can be used, and as a coating method, soaking or spraying can be adopted.

[0020]

[Embodiment 3] When the trunk (stem) of the potted seedling 10 is planted at a position away from the center of the root pot portion 11, the pin 3
Damage to the root system 13 due to the implantation of 0 can be minimized. When the seedlings 12 are inclined (obliquely upward) instead of perpendicularly to the root pot 11, the hose for spraying the vegetation base material can be more easily dodged.

[0021]

As described above, the present invention has the following effects.

<A> Before the planting of the potted seedlings, cutting back of the branches and leaves is performed to maintain the balance between the water requirement of the seedlings and the water absorption of the root system, and the mortality of the seedlings becomes extremely low.

<B> Since the branches and leaves of the seedlings have been cut back, the dosing operation of the hose for spraying the plant growth base material can be easily performed, and the fall of the potted seedlings and the damage of the seedlings can be avoided.

<C> Since the branches and leaves have been cut back, there is no need to cover the potted seedlings from the vegetation base material, and the time and labor required for construction can be greatly reduced.

<D> Since the root pot portion of the pot seedling is formed thin, stability on the slope is improved.

<E> Since the thickness of the root pot is set to be almost as thin as the sprayed thickness of the vegetation base material, the loss of the vegetation base material is reduced and the vegetation base material can be effectively used. .
