Description

[Detailed description of the invention] [Industrial application field] The invention relates to a vegetation cover net used for vegetation on a sloping land or a hillside.

[Conventional technology]

When plant seeds are sown on a slope and vegetated, effective vegetation is not achieved if the seeds collapse with the surface soil of the slope after the direct sowing or the seeds are washed away by being exposed to wind and rain.

Therefore, it has been often practiced to cover such a vegetation covering net made of synthetic resin on a slope directly sown with seeds to prevent such a situation from occurring.

[Problems to be solved by the invention]

However, when a synthetic resin vegetation covering net is put on the slope, the above-mentioned situation can be suppressed, but on the other hand, ventilation or sunshine to the germinated plants is hindered by the covering net. On the other hand, there is an inconvenience that the plant is held down by the mesh thread and its growth is inhibited.

In view of the above circumstances, the present invention is based on the fact that certain materials have the property of gradually decaying so as to decay by irradiation of light (especially ultraviolet rays) and the action of living things, and that certain materials or appropriate treatment The purpose of this study was to pay attention to the fact that the treated material had water retention, and the roots of the seeds were likely to collapse along with the surface soil of the slope and to be washed away by the wind and rain. Until there is no need to worry, the occurrence of the above-mentioned situation can be prevented by the same effect as a covering net as before, and after the seeds have taken root, ventilation and sunlight on the plant are not hindered, and the net thread It is an object of the present invention to provide a vegetation covering net that does not cause inconvenience such as holding down plants.

[Means for solving the problem]

One vegetation cover net of the present invention is biodegradable,
And a yarn formed by adding a material having water retention to a yarn made of a material having disintegration by light.

Another vegetation covering net of the present invention is made of a yarn having a water retention hole between yarns made of a material having disintegration properties by living organisms and disintegration by light.

[Action]

This cover net for vegetation plays a role of preventing the loss of plants as a cover net within a certain period after construction on the slope,
As time passes, it deteriorates so as to gradually decay due to creatures in the ground and sunlight, particularly ultraviolet rays, and collapses even with subtle force. Therefore, it is necessary to select a material that can maintain the strength required for the coated net until the seeds take root, and that has the ability to disintegrate by living organisms and disintegrate due to light so that the seeds can easily disintegrate after they have taken root. The need is met when it is necessary to control the loss of seeds,
After the need is gone, the plants will grow unhindered by the covering net.

In addition, since the vegetation coating net has water retention, germination disorders due to drying of seeds are prevented beforehand.

〔Example〕

FIG. 1 shows a vegetation covering net A according to an embodiment of the present invention, wherein 1 is a warp and 2 is a weft, which are combined in a grid pattern and their intersections P are joined. The warp yarn 1 and the weft yarn 2 are yarns formed by adding a water-retaining material to a yarn made of a material having disintegration by light (photodisintegration) and disintegration by living matter (biodisintegration), or photodisintegration. This is a yarn with a water retention hole between yarns made of a material having properties and biodegradability.

Materials having biodegradability and photodisintegration include, for example, a material in which starch is blended with polyethylene, and materials having a water retention property include cellulosic nonwoven fabrics or woven fabrics such as poval, cotton, and hemp. It is not limited to. As a method for providing the warp 1 and the weft 2 with photodegradability, biodegradability, and water retention, a method of forming the warp 1 and the weft 2 from a material having photodegradability, biodegradability, and a material having water retention is used. In addition, there is a method of laminating or winding a material having water retention properties on a warp 1 and a weft 2 made of a material having photodegradability and biodegradability. further,
It may be one in which thin fibrous yarns made of a material having photodisintegrability and biodegradability are gathered and a water retention hole is provided between the yarns. As means for joining the intersection P, various means such as heat fusion, sewing, joining with an adhesive, and bundling can be adopted, but the mesh can be maintained without joining the intersection P. If possible, it is not necessary to join.

The warp yarn 1 and the weft yarn 2 may have a circular cross-sectional shape with a diameter of several mm, but it is more preferable that the warp yarn 1 and the weft yarn 2 have a flat band shape. The effect of preventing seed loss is improved. When making the warp yarn 1 and the weft yarn 2 into a flat band shape, the width
mm or less, and the width of such a range can sufficiently prevent the seeds from flowing out and supply water to the seeds, and does not cause inconvenience in handling during storage and construction. Needless to say, those having a width larger than the above-mentioned width of 10 mm are used as needed. When the covering net A has a grid-like net 3 as shown in the figure, it is desirable to set the length of one side of the net 3 in the range of 10 to 50 mm. With this size, the germinated plants are
Grow comfortably through. If the mesh 3 is too small, the growth of the plant will be inhibited, and if it is too large, the effect of preventing the loss of seeds will not be effectively achieved.

When the covering net A for vegetation is constructed, the warp 1 and the weft 2
Network A maintains the strength required for the vegetation coating network within a certain period after construction when deterioration of the soil has not progressed so much. The creature's disintegration progresses and warp 1 and weft 2
It gradually changes as it rots, and gradually becomes easily collapsed. Therefore, the warp yarn 1 and the weft yarn 2 gradually change so as to decay and gradually become easily collapsed. Therefore, by appropriately setting the materials of the warp 1 and the weft 2, the warp 1 and the weft 2 can be disintegrated so as to decay in accordance with the germination time of the seed sown on the slope, and by doing so, the seed In the period until the roots take root, the covering net A effectively prevents the outflow of the seeds, and when there is no danger of the seeds flowing out, that is, in the period after the seeds are rooted, the warp 1 and the weft 2 are subjected to the power of wind and rain, soil and soil. It breaks down by contact with the plant, so that the growth of the plant is not inhibited.

Seeds and fertilizers can be attached to the vegetation coating net A of the present invention, and the seed net can be omitted by spreading the coating net A on the slope.

[Effect of the invention]

As described above, the vegetation cover net of the present invention meets the need by maintaining the necessary strength at the time when it is necessary to suppress the loss of seeds, and after the necessity is eliminated, the action of light and organisms Therefore, there is an excellent effect that the plant grows without being disturbed by the covering net because it deteriorates so as to gradually rot and collapses even with a small force. In addition, germination failure due to drying of the seeds is prevented beforehand by the water retention.

In addition, the vegetation coating net of the present invention can be stored in a rolled shape (rolled shape) like a normal synthetic resin net, and can be constructed by expanding it, so that storage and construction are easy. There is also an advantage.
