Description

[Detailed description of the invention] [Field of industrial application] This invention relates to the improvement of pine vegetation used for greening vegetation for mountainside collapse restoration and 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 the slopes of collapsed mountains and reclaimed land, and the seeds of trees and other plants inside it germinate and grow roots, thereby promoting greening and forest restoration.

Conventionally, this kind of vegetation pine was made by pasting a large number of straw grass in parallel and in one or two layers with an appropriate porosity on the top surface of water-soluble paper with seeds adhered to it. Machine stitched with thread is 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.

[The problem that the idea attempts to solve]

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. For this reason, in reality, the rope had to be fixed with toothpicks or bamboo skewers and then further strung out diagonally, which took a lot of time.

In addition, straw tends to become a nesting place for pests and is a factor that reduces the germination rate of seeds.

On the other hand, in recent years, with the spread of advanced agricultural machinery, straw has been cut into small pieces and sown at the same time as rice harvesting, which has come to be used for geological improvement, making it difficult to obtain straw. be.

Additionally, wood fibers are known to have several times higher rot resistance than straw, as well as water retention and bactericidal properties.

This invention was made in view of the above, and aims to provide a vegetated pine that has good construction workability and stability on slopes, and is suitable for seed germination.

[Means to solve the problem]

In order to achieve the above purpose, the first idea is to provide a vegetated pine with a porosity of 50 to 80% formed by rolling.
The invention consists of a wood fiber mat, a net laminated to the upper surface of the wood fiber mat, and a water-soluble sheet having seeds adhered to the upper surface and laminated to the lower surface of the wood fiber mat.

In addition, the second idea is to use rolled-formed wood fiber pine with a porosity of 50 to 80%, a net attached to the top surface of the wood fiber pine, and a seed sandwiched between the upper and lower two layers of the vegetated pine. and a water-soluble sheet laminated to the lower surface of the wood fiber mat.

[Effect]

According to this invention, the germination rate of seeds is improved due to the rot resistance, water retention and sterilization properties of the wood fiber pine. Moreover, the fixation by the fixing member is stably maintained for a long period of time by the net.

Furthermore, since the seeds are glued to the top surface of the water-soluble sheet or sandwiched between the upper and lower layers of the water-soluble sheet, they will not be blown away or washed away by wind or rain.

〔Example〕

FIG. 1 is a perspective view showing an embodiment of the structure of a vegetated pine according to this invention, and FIG. 2 is a sectional view thereof.

This invention will be explained below using FIGS. 1 and 2.

In the figure, 1 is wood fiber pine rolled into a squid shape, 2 is an appropriate amount of tree seeds for greening, other fixed fertilizers and water retention materials for germination and growth, and 3 is 4 is a water-soluble sheet made of water-soluble paper or the like, and 5 is a water-soluble adhesive, the total thickness of which is, for example, about several millimeters to 1 cm. Also, the overall size is, for example, width 1
m, the length can be about 10m.

The above-mentioned wood fiber mat 1 is made of ordinary wood as well as
For example, in the cultivation of afforestation trees, thinned-cut lumber that has been thinned out to grow thicker and larger, leftover wood from lumber processing, and the like can be effectively utilized, and for example, it can be formed in the following manner. That is, the above-mentioned simple cutting material is cut to a predetermined length, and this is rotated in a direction perpendicular to the axis, and a cutting blade of a predetermined length is attached to the rotating surface so as to be movable back and forth. It is scraped into a thin plate shape, the plate thus obtained is shredded in a certain direction, and further rolled into a squid shape using a pressure roller or crushed to have a porosity of 50~50. This is about 80%. The above-mentioned porosity was obtained by considering the germination rate, loss, etc., and is set within a desired range depending on the type and number of seeds.

The net 3 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 4 is provided on the lowermost surface, and seeds etc. 2 are adhered to the upper surface thereof with a water-soluble adhesive 5, and is laminated to the lower surface of the wood fiber sheet 1. This bonding work can also be performed by spraying as described above. The water-soluble adhesive 5 was designed and adopted so that it would dissolve by the time the seeds 2 germinate and grow roots. Note that the water-soluble adhesive 5 does not necessarily have to be water-soluble by adjusting its amount.

In this way, an integrated vegetation pine is formed by pasting the whole together.

Next, FIG. 3 shows another embodiment of this invention, in which water-soluble sheets 4 are provided on both sides with seeds 2 interposed therebetween.

This effectively prevents the seeds 2 from scattering or being washed away, and also makes it possible to manufacture the water-soluble sheet 4 side and the wood fiber mat 1 side in separate processes, improving manufacturing efficiency.

Note that solid fertilizer and water retention materials are not necessarily necessary.

[Effect of idea]

According to this invention, by using wood fiber pine, it is possible to improve the germination and growth rate of seeds due to its excellent rot resistance, water retention and sterilization properties.

Furthermore, since the net is bonded to the top surface of the wood fiber mat, it is possible to stably maintain the laying and fixing to the ground for a long period of time.

Furthermore, since the seeds are glued to the top surface of the water-soluble sheet or sandwiched between the two upper and lower layers of the water-soluble sheet, it is possible to effectively prevent the seeds from scattering or being washed away. Since the mat side and the mat side can be manufactured in separate processes, manufacturing efficiency can be improved.
