DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables a planted tree to grow reliably on a slope formed by road construction, etc., and at the same time, enables stable maintenance of the slope surface and greening by vegetation. The present invention relates to a novel slope planting method that can be suitably used in the case of (1).

[0002]

2. Description of the Related Art Conventionally, tree planting on rock slopes has
Partially dig a hole and throw in fertilizer to plant pot seedlings, or concrete, wood, etc.
It was implemented by providing earth retaining parts such as plant boxes.

[0003] That is, the former planting method firstly involves the steps of FIG.
As shown in the figure, a planting hole 41 is dug in the slope 40, and then,
The excavated soil 42 is mixed with a soil improving material 43 such as bark compost (see FIG. 8), and a pot seedling 45 taken out of the pot 44 is installed in the center of the planting hole 41.
The soil 42 mixed with the soil improving material 43 is returned to the planting hole 41 and the depth of the planting hole 41 is adjusted (see FIG. 9).
The soil is covered to the extent that the root mortar of the pot seedling 45 is hidden, and the soil 42 is buried around the planting hole 41 (see FIG. 10).

In the latter planting method, in FIG. 11, a diagonal digging is performed on a slope 40 in a diagonal direction, a pile 50 is hit, and for example, bamboo 51 is assembled to form a retaining portion 52, and a retaining portion 52 is formed. After that, the potting seedlings 45 were planted in the excavated site with the soil suitable for planting, and the soil was finally covered with a straw 54 and fixed with ropes 55.

[0005]

However, in the former method, only the planting hole 41 is dug in the slope 40, so that the portion of the planting hole 41 is easily broken by rainfall or the like.
There is a problem that the soil serving as a growth base is easily washed away.
In particular, the front end portion of the planting hole 41 is likely to collapse. Therefore, the planting hole 41 having a large capacity could not be dug, and the soil serving as a growth base was reduced, and root growth was poor, and poor growth and wind-induced trees caused by wind were observed.

In the latter method, there is a problem that the construction such as forming the earth retaining portion 52 is large.

On the slope, a plurality of small steps are formed in a plurality of steps, and logs are juxtaposed on the upper surface at the front end portion of each of the steps, for example, in three upper and lower steps. It is also conceivable to perform embankment and plant trees.

Although this method is advantageous in that the use of logs can prevent soil from being washed away due to rainfall or the like, since logs are not flexible, there is an uneven surface on the upper surface of the small step portion. In addition, the workability is deteriorated, and the soil serving as the growth base is also easily spilled from between the logs and the uneven surface. Therefore, poor root growth may occur, and poor growth or wind-induced fallen trees due to wind may be considered. Moreover, this construction method
Although it is necessary to fix the log in order to juxtapose the log on the upper surface of the step portion, it takes considerable trouble to stop the log.
