Long-term absorption of water from rainfall and rainfall, and organic matter and soil particles have sufficient fertilizers and nutrients, so that plants can grow well even on soil with low nutrients, ensuring reliable greening at low cost Becomes possible.

Particularly, since the vegetation base material block is formed in a horizontally long rectangular parallelepiped shape, one block contributes to the growth of a large number of plants planted around the block, and enables dense and uniform greening.

Further, by burying a vegetation base material block having a plurality of small holes in the vertical direction in the cover soil, the small holes ensure good air permeability of the entire block, and the roots of the plants are kept at the roots. By penetrating into the stoma, the root circumference is good, and vigorous reproduction is promoted. In addition, plant seeds can be sown through the stoma and securely held, or seedlings and bulbs can be planted and held.

Further, by embedding a vegetation base material block having a concave portion on the upper surface in a cover soil, a large number of seedlings, bulbs or seeds having a large height planted with a lot of soil in the concave portion are surely held. It can be installed on the ground in a state where it is set.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 show the construction state of a greening work according to the present invention. After a net 2 is stretched on a ground 1 such as a cut retaining wall or a cut slope, FIG. An organic vegetation base material block 3 is fastened to the ground 1 by a stopper pin 4 or the like, and is installed vertically and horizontally at required intervals.

[0010] Thereafter, a covering material in which a solidifying material such as fibers and cement is mixed with the soil and sand is sprayed on the ground 1 and compacted by the discharge pressure of high-pressure air or the compaction pressure of a rammer or the like to form a high-density mixing aid.

The slope is covered as a strong soil, and a plant for greening is planted in the covering soil 5, or plant seedlings or seeds are planted in advance or in the vegetation base material block 3 and sprayed with covering soil. They may be bred later.

The vegetation base material block 3 is composed of various fibrous or granular organic substances such as peat moss and bark compost, and soil particles such as perlite and vermiculite having good water retention and fertilizing properties, as well as compost and plant ash. These fertilizers are mixed and formed into a horizontally long rectangular parallelepiped shape, and are formed by pressing, or by adding a binder such as bentonite or a resin binder and consolidating to form a horizontally long rectangular parallelepiped block.

As an example of the vegetation base material block 1,
As shown in FIG. 3, a plurality of small holes 6 are provided in the up and down direction in the installation state at the time of use to improve air permeability and root circumference of the plant, and the small holes 6 are previously filled with plant seeds and small seedlings together with soil material. Be able to plant.

The seeds and the like may be mixed and planted on the surface of the vegetation base material block 3 when the vegetation base material block 3 is formed.

As another embodiment, as shown in FIG. 4, a vegetation concave portion 7 is provided on the upper surface of the vegetation base material block 1, and a lot of seedlings having a large plant height are prepared by putting soil into the concave portion 7.
The bulbs or seeds may be installed on the ground with the soil being held securely.

The bottom of the vegetation recess 7 is formed as shown in FIG.
It is preferable to provide a plurality of small holes as in the embodiment.

In the above embodiment, the case where the vegetation base material block 3 is buried in the cover soil 5 has been described. However, a concrete greening block is installed on the ground 1 closely in the left, right, up and down direction, and a front surface of the greening block is provided. It is also possible to use the vegetation base material block 3 in the provided horizontally long rectangular vegetation concave portion and to plant the seeds or the seedlings in the vegetation base material block 3.

[0018]

As described above, according to the present invention, the roots of plants grow and propagate in the vegetation base material block buried in the cover soil, and the ground is retained by the excellent water retention and water absorption of the block. Water for a long period of time
In addition, since organic matter and soil particles have a sufficient amount of fertilizer and nutrients, plants can grow well even in soil with little nutrients, and reliable greening can be performed at low cost.

Since the vegetation base material block is formed in a horizontally long rectangular parallelepiped shape, a single block contributes to the growth of a large number of plants around the block, enabling dense and uniform greening.

In addition, by using a vegetation base material block having a plurality of small holes in the vertical direction, the small holes ensure good air permeability of the entire block, and the roots of the plants enter the small holes. Thus, the root circumference is good, and vigorous reproduction is promoted. In addition, plant seeds can be sown through these small holes to reliably hold them, or seedlings and bulbs can be planted and held.

Further, by using a vegetation base material block having a concave portion on the upper surface, soil is put in the concave portion, and a large number of seedlings, bulbs or seeds planted in large numbers and planted securely in the ground. Or can be used by filling in a greening block.
