DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope revegetation method in which seedlings are planted on a slope formed by road construction or the like to achieve greening, and in particular, lawn seeds are adhered to a nonwoven fabric or the like. By growing the upholstered turf or raw turf on the slope and planting tree seedlings or ground seedlings (hereinafter referred to as pot seedlings) etc., which are raised in a standard plastic pot, etc. The present invention relates to a new slope revegetation method capable of securely growing trees on a slope, stably maintaining the slope surface, and greening with vegetation.

[0002]

2. Description of the Related Art A so-called upholstery body in which turf seeds are adhered to a non-woven fabric (or a piece of paper) on a slope, or a so-called upholstery such as korai turf, is used to grow trees. In this case, a method of planting tree seedlings including tree seeds in lawn seeds (hereinafter referred to as tree seedlings) has been adopted, but tree seedlings with slow initial growth are used.
It is under pressure by fast-growing grass seedlings, and it is difficult to plant tree seedlings reliably.

[0003] The present invention has been made in view of the above-mentioned problems, and an object thereof is to grow upholstered turf or fresh turf in which lawn seeds are adhered to a nonwoven fabric or the like on a slope formed by road construction or the like. At the same time, it is an object of the present invention to provide a slope revegetation method that can reliably plant tree seedlings.

[0004]

Means for Solving the Problems To achieve the above object, a slope greening method according to the present invention is characterized in that a hole is formed on a slope and lawn seeds are adhered to a nonwoven fabric or the like around the hole, or a lawn grass or a green grass. The turf is attached, and the hole has a shape that is cut diagonally to the hole so that the lower opening surface matches the shape of the slope.
And on the peripheral wall, there is an ear with an anchor holding hole

Established a bamboo planting container ring for anchoring the ing fixed, since inserting the soil and seedling in the planting container,
In addition to supporting the tree seedlings by the planting container, the planting container can form a soil retaining portion for preventing the soil, which serves as a growth base, from being washed away or collapsed.

For example, when planting a pot seedling, the pot seedling can be easily and reliably planted by a simple operation of merely putting the pot seedling taken out of the vinyl pot into the planting container. And the root of the planted pot seedling can be easily extended from the inside of the planting container to the ground surface. Also, the when the planting container is placed into the hole, nothing can stabilize the peripheral portion of the hole than can contribute to stable holding of the thus slope surface.

[0007] In other words, when planting by simply digging a hole on the slope, there is a problem that the portion of the hole is liable to collapse due to rainfall and the like, and the soil serving as a growth base is easily washed away. It is difficult to dig a hole with a large capacity, and the soil that serves as a growth base is reduced, root growth is poor, and poor growth and the occurrence of wind-killed trees due to wind are observed. According to the present invention, trees can be grown safely and reliably only by installing the planting container in the hole . Further, in the present invention, the earth retaining portion can be formed only by installing a planting container in the hole without performing a large-scale construction.

In FIG. 1 to FIG. 3, reference numeral 1 denotes an upholstered body laid on a slope 2, and a lawn seed 4 is adhered to a nonwoven fabric 3 with a water-soluble glue 5. As the non-woven fabric 3, a known non-woven fabric is used, and a water-soluble non-woven fabric having excellent dispersibility, in which narrow long fibers are mainly bound in one direction, is preferable, for example, 1.5 denier, 51 mm in length. Is converted to, for example, polyvinyl alcohol (P
Using a water-soluble glue obtained by mixing a small amount of a water-repellent agent into a water-soluble resin such as VA), the material ratio is, for example, 80% of the fiber, the water-soluble glue is 20%, and the basis weight is about 23 g / m ^2. Use what is bound so that

The water-soluble paste 5 includes polyvinyl alcohol.

The grass seeds 4 include, for example, grass seeds, wild grass seeds, woody seeds, and flower seeds shown below. Pasture seeds: Kentucky 31 fescue, weeping love grass, white clover, creeping red fescue, red top, bermuda grass, Kentucky blue grass, etc. Wild grass seed ... mugwort, Medohagi, pampas grass, Japanese knotweed and the like. Seeds of flowers: gypsophila, cosmos, cornflower, kawaraneshiko, sekichiku, giant flower, yellow daisy, french chrysanthemum, saw grass, california poppy,
Murasaki Hanana, Celosia, Teningiku, etc.

When the lawn seeds 4 are to be attached to the nonwoven fabric 3, a fertilizer, a water retention material, or the like may be attached simultaneously as appropriate.

In order to plant green by planting seedlings on the slope 2 using the upholstery body 1, first, as shown in FIGS. 1 to 3, the slope 2 is appropriately shaped, and then the nonwoven fabric 3 is placed on the lawn. The upholstered turf 1 is laid on the slope 2 such that the surface on which the seeds 4 are provided is close to the slope 2. After the surface on which the lawn seeds 4 of the upholstery body 1 are provided is brought into close contact with the slope 2, the upholstery body 1 is fixed using a holding member 6 such as an anchor.

At this time, a hole 7 is dug at an appropriate interval in the slope 2, and the upholstery 1 is fixed to the slope 2 including the hole 7.
Subsequently, the opening 1a may be formed by cutting the portion of the upholstered turf 1 corresponding to the hole 7 or, alternatively, after fixing the upholstered turf 1 to the slope 2 and cutting the upholstery 1 at appropriate intervals. It is also possible to form the opening 1a and to dig a hole 7 in a slope portion of the opening 1a. In addition, the order of forming the opening 1a and digging may be variously combined.

The lawn seeds 4 attached to the upholstery body 1
Is germinated by receiving the rainfall or the like, the water-soluble glue 5 is melted and falls on the slope 2. That is,
The lawn seeds 4 germinate immediately upon encountering the moisture, and the young shoots easily emerge from the space of the fibers of the nonwoven fabric 3, absorb fertilizers and water retention materials, and grow into grass, wild grass, flowers and the like as appropriate. To form a uniform and even grass surface. This growth is faster than that of tree seeds such as, for example, Yamahagi and Akamatsu, which will be described later.

Next, a planting container 8 is placed in the hole 7 of the slope 2 including the upholstery body 1 having the opening 1a, and seedlings are raised in the hole 7 with a fixed-size vinyl pot (not shown) or the like.
