Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vegetative pine that is used for greening vegetation for mountainside collapse recovery and restoration, or for greening vegetation on slopes such as reclaimed land in general civil engineering work.

[Conventional technology]

Vegetation pine is a type of pine that is widely spread on collapsed mountainsides and slopes of reclaimed land, and seeds of trees and other plants germinate and grow roots from within, promoting greening and forest restoration.

Conventionally, this type of vegetated pine was made by pasting a large number of straws in parallel, in single or double layers, with an appropriate porosity on the top surface of water-soluble paper with seeds adhered to it, and then threading this straw. Machine-sewn items are used.

When such vegetated pine is laid on the slope of a mountainside or reclaimed land, it is fixed by inserting toothpicks, bamboo skewers, etc. from above the pine into the ground at desired intervals.

[Problem to be solved by the invention]

However, since straw is used for the vegetative pine, it is susceptible to rotting especially under the influence of weather such as rainwater, and after a while it is blown away by wind and rain or washed away. Therefore, in reality,
After being fixed with toothpicks or bamboo skewers, the ropes had to be laid out in diagonal lines, which took time.

In addition, straw easily became a nesting ground for pests and was a factor that reduced the germination rate of seeds.However, in recent years, advanced agricultural machinery has become widespread, and rice harvesters cut straw into small pieces at the same time as harvesting. As straw has come to be sown and used for geological improvement, it is now difficult to obtain straw.

In view of the above-mentioned problems, the present invention provides an economical vegetated pine that has good construction workability and stability on slopes, is durable, suitable for seed germination, has raw materials easily available, and is economical. The purpose is to

[Means to solve the problem]

In order to achieve the above object, the gist of the present invention is to use a fibrous wood fiber pine mainly formed by rolling wood in a vegetative pine containing seeds for greening.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the vegetation pine according to the present invention will be explained based on the illustrated embodiments.

FIG. 2 is a perspective view showing an example of the structure of a vegetation pine made of wood fiber pine.

In the figure, 7 is a wood fiber pine pressed into a squid shape, 8 is a plant seed for greening, fixed fertilizers and water retention materials for the germination and growth of other seeds, 9 is a net, and 10 is a A water-soluble sheet made of water-soluble paper, 11 is a water-soluble adhesive. Vegetation pine has a thickness of, for example, several millimeters, and
Although the overall size is generally about 1 m in width and 10 m in length, it is not limited to this.

The above-mentioned wood fiber mat 7 is made of ordinary wood,
For example, by using thinned wood or leftover wood from lumber processing,
It is formed as described below.

The net 9 is formed by knitting or integrally molding filaments made of, for example, synthetic resin, and is bonded to the top surface of the wood fiber mat by spraying an adhesive or the like. The water-soluble sheet 10 is provided on the lowermost surface, and seeds, etc. 8 are adhered to the upper surface thereof using a water-soluble adhesive 11, and is bonded to the lower surface of the wood fiber mat 7. The adhesion between the water-soluble sheet 10 and the seeds, etc. 8 using the water-soluble adhesive 11 may be done by spraying, similar to the above-mentioned net 9, and the water-soluble sheet 10 may be attached to the seeds, etc.
It may be made into two layers, upper and lower, with the two layers sandwiched in between. In this way, an integrated vegetation pine is formed by laminating the whole.

Now, FIG. 1 is a process diagram for explaining an example of a method for manufacturing the wood fiber mat 7. As shown in FIG.

In the figure, 1 is a piece of wood having a desired radius and length, 2 is a piece of wood that moves back and forth in the A direction, and the piece of wood 1 has a desired radius and length.
3 is a thin plate cut to a thickness of about 1 to 10 mm, 4 is a long thin cutting blade that moves in the vertical direction, 5 is a thin piece of the thin plate 3, 6,
6' is a rolling roller, and 7 is a wood fiber mat crushed into a squid shape.

First, as shown in FIG. 1A, a piece of wood 1 having a desired radius and a predetermined length is prepared by cutting thinned wood or the like.

Next, as shown in Figure b, the piece of wood 1 is held by a rotating mechanism (not shown) and rotated at a constant speed so as to rotate about its axis L-L'. At the same time, the cutter 2 disposed parallel to the axis L-L' is sequentially advanced toward the wood piece 1 side indicated by the arrow A, and the rotating piece of wood 1 is cut, for example, by about 1 to 10 mm, as shown in Figure c. Cut into a thin plate 3 of the same thickness. The thickness of the thin plate 3 can be adjusted as desired by the rotational speed of the wood piece 1 and the speed at which the cutter 2 is advanced.

The thin plate 3 thus obtained is then cut into a large number of elongated pieces 5 by vertical movement of the chopping blade 4, as shown in FIG. Then, in the next step, it is sent to rolling rollers 6 and 6' prepared, and is crushed by the pressing force thereof to form a thin squid-shaped fiber.

If the wood fiber mat 7 shown in FIG. Ru.

Note that instead of pressing by the rolling rollers 6, 6',
It may be simply crushed by vertical movement.

In addition, when using rolling rollers 6, 6' in which a large number of micro grooves are formed along the rotation direction (or at some angle) on the circumferential surface of the rolling rollers 6, 6',
The formation of the plurality of pieces described above and the rolling into squid shapes can be carried out simultaneously.

Furthermore, the piece of wood 1 does not have to be cylindrical, and may be a square column, although the square portion is wasted.

That is, it is sufficient if it has a desired thickness.

Further, the piece of wood 1 does not have to have a fixed length, but may have a predetermined length that falls within a certain allowable range in relation to the rotation mechanism or the length of the blade of the cutter 2.

On the other hand, when the water-soluble sheet 10 has two layers, the bonding of the water-soluble sheet 10 and the seeds 2 is as follows:
First, the rolled lower water-soluble sheet 10 is sent out, seeds 2 are sequentially sown from above from a tank, etc. on the delivery path, and adhesive is sprayed, and then the rolled upper water-soluble sheet 10 is sent out from above the downstream position. This can be done by spraying the adhesive while sending out the adhesive sheet 10. Then, an integrated vegetation pine is manufactured by spraying adhesive onto this and the above-mentioned wood fiber pine 7 side.

〔Effect of the invention〕

The vegetated pine of the present invention has excellent rot resistance, water retention, and sterilization properties, and therefore has good workability and fixability to slopes, is durable, and is suitable for seed germination. Furthermore, since wood is used as a raw material, the raw material is easily available and the vegetated pine can be manufactured at low cost.
