Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soilbag for planting, and in particular, it is difficult to drill a planting hole for planting.
The present invention relates to a planting sandbag for planting pot seedlings, seedlings, and the like on a hard steep slope made of hard rock, soft rock, hard soil, or the like.

[0002]

2. Description of the Related Art Hard steep slopes made of hard rock, soft rock or hard soil are difficult to grow as they are.
Most of them have exposed hard rocks and the like, giving a very scenic landscape. Therefore, in recent years, there has been a demand for planting pot seedlings, seedlings, and the like on such steep slopes to form a beautiful landscape by the “green” of the plants.

However, the steep slope has hard rocks and the like exposed on the surface as described above, and is literally a steep slope, so that a planting hole for planting is drilled. Is difficult. Because steep slopes of this kind are located at high altitudes or in places where cars and machines are difficult to enter, such as mountainous areas, drill holes in these For this reason, it is necessary to rely on manual labor, and it is very difficult for a person to work on a steep slope.

[0004] Further, such a steep slope is made up of hard rock, soft rock, hard soil, or the like, so that it is very dry, and even if planted, it will die early.

[0005] In order to plant such a hard steep slope, conventionally, a sill fence or spray frame is first formed, and a plant vegetation base material is planted in the fence or frame. Pack the soil material and plant it, or place a sandbag filled with vegetation base material inside a fence, etc., cut out the surface side of this sandbag and make a hole for planting. A method such as planting was adopted. However, forming these fences and frames on steep slopes is a very difficult task as described above, and these construction methods are very limited, as there is a high possibility that a disaster will occur. It could only be applied to those places.

Even if constructed, the surface of the soil in the fences and frames, or the surface of the vegetation base material of the sandbag that has been cut open, is left exposed to the outside. The soil and vegetation base are very dry and run off by rainwater. In addition, there is a problem that the weeds that are exposed tend to invade the exposed soil and the like, and the weeds cause the plants to decline.

On the other hand, as a conventional technique, on a steep slope,
A method was adopted in which a thin vegetation mat with seedlings planted was fixed with nails or anchors.However, vegetation mats are difficult to use because the target slope is steep and has severe irregularities. Adhesion to the surface was poor, drying was quick, and growth of seedlings and the like was often poor. There is also a method of fixing planting boxes and frames made of water-resistant corrugated cardboard to plant soil and planting on them.However, this method tends to lack the amount of soil and tends to be sufficient for planting. Can not be expected to grow. Further, in these methods, as described above, it is difficult to fix the vegetation mat with nails or the like, or to fix the planting box or the frame to the steep slope.

Therefore, the present inventor has proposed how to make planting on a hard steep slope made of hard rock, soft rock, hard soil, or the like safe, excellent in workability, and effective. As a result of various studies on squid, the present invention was completed.

[0009]
