DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention relates to slope greening method to achieve greening by planting the seedlings slope formed by the road reclamation, etc. are grown especially the slopes of vegetation by Choshibatai At the same time, by planting tree seedlings and plant seedlings such as ground cover plants, new trees can be surely grown on the slopes, and a new slope revegetation method that enables stable maintenance of the slopes and greening with vegetation. It is about.

[0002]

2. Description of the Related Art As a method of introducing a tree on a slope and coexisting with a herbaceous plant to create a well-balanced landscape, a mixed seeding of a tree seed and a herbaceous seed, a planting of a tree seedling are known. Although there are methods such as a combination of mixed seeding of cultivation and herbaceous seeds on slope, nonwoven (or paper) was stuck to herbaceous seeds as grass seeds, planting trees After performing affixed called Choshibatai And when growing, the seedlings of the early growth are pressured by the fast growing herbs,
It is difficult to grow tree seedlings reliably and soundly.

[0003] The present invention has been made in view of the above-mentioned problems, and an object thereof is to grow vegetation on a slope formed by road construction or the like by using upholstery , and to ensure that tree seedlings are healthy and healthy. It is an object of the present invention to provide a slope revegetation method that can be grown on a slope.

[0004]

Means for Solving the Problems In order to achieve the above object, a slope greening method according to the present invention forms a turf surface by turf seeds being fixedly held on the slope and germinating and growing the turf seed. The upholstery body and the hole configured as described above are provided, seedlings are planted in the hole, and a covering member that covers the upholstery body or the slope is provided around the hole. .

According to another aspect of the present invention, there is provided an upholstered turf body and a hole configured so that a turf seed is fixedly held on a slope and forms a turf surface by germination and growth of the turf seed. Planting a seedling in the hole, providing a covering member for covering the upholstery or the slope around the hole, and further providing a support for supporting the seedling on the covering member. I do.

[0006]

The upholstery and the hole are provided on the slope , seedlings are planted in the hole, and a covering member for covering the upholstery or the slope is provided around the hole. To prevent tree seedlings that are late from being overwhelmed by herbs such as fast-growing grasses, wild grasses and flowers that germinate and grow on the body , or invasion of weeds that grow on the body and slopes around the hole Can be prevented.

[0007] Moreover on the tree seedlings is supported by a support provided on said cover member, since the support presses the cover member on the face of slope side, the Choshibatai or coating member itself around the hole Close contact with the slope. Therefore, the water retention effect around the planted tree seedlings can be enhanced. That is, the slope that has absorbed water due to rainfall or the like is unlikely to dry due to the influence of wind or the like, and can store water necessary for growing tree seedlings.

For example, when planting a pot seedling, the pot seedling can be easily and reliably planted by a simple operation of only supporting the trunk portion of the pot seedling taken out of the vinyl pot with the support. it can. And the root of the planted pot seedling can be easily extended to the ground surface.

Further, when the covering member is provided around the hole, the peripheral portion of the hole can be stabilized above all, which can contribute to the stable holding of the slope surface. That is, when planting only by digging a hole on the slope, there is a problem that the portion of the hole is likely to collapse due to rainfall and the like, and the soil serving as a growth base is likely to be washed away, and in particular, the front end portion of the hole is likely to collapse. Therefore, it is not possible to dig a hole with a large capacity, the soil serving as a growth base is reduced, root growth is poor, and poor growth and occurrence of wind-down trees due to wind are observed. Just install the covering member around the hole,
Trees can be grown safely and reliably.
