Abstract

PROBLEM TO BE SOLVED: To realize uniform seeding at a fixed ratio by mixing and dispersing seeds with fluff into a cottonlike fiber to form a mat. SOLUTION: A cottonlike fiber 2 and seeds with fluff 3 are mixed to form a straw mat by a molding means 6, a net body 5 is pressurized and bonded on its surface by a pressurizing roller 9 to form a mat 4, and then, it is cut to predetermined length at A point to form a seeding basic body 1. Corrosive staple fiber cotton is used as the fiber 2 and is corroded and collapsed gradually after the basic body 1 is spread and provided to facilitate the germination and growth of seeds and reduce residual material after plants grow. Next, when a normal face is greened, the basic body 1 is fixed on the normal face by using an anchor so that it does not slide down. At this time, since the basic body 1 is cut at fixed dimension, the construction and transportation become easy. Moreover, since seeds 3 are mixed and dispersed in the cottonlike fiber 2 to manufacture the mat 4, the seeds can be mixed uniformly at fixed distribution even if the seeds 3 are seeds with fluff.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a seed-seeding substrate for fluffy seeds used for revegetation, for example, on slopes of hillsides and rivers, and on slopes formed during road construction and land reclamation. The present invention relates to the manufacturing method.

[0002]

2. Description of the Related Art In general, the above-mentioned slope is planted by planting a plant for protection and preservation of the landscape. When greening is performed using the seeding substrate, it is desired that the seeding substrate has good adaptability to the slope of the seeding substrate, and that the workability is good and the cost is low in order to improve the germination and growth of the plant seeds. . Therefore, the present applicant has already proposed a seeding substrate in which plant seeds and the like are attached to a mat made of a material that can be partially decomposed.

FIG. 4 shows a configuration of a conventional seeding substrate 20 and a manufacturing process thereof. In FIG. 4, reference numeral 12 denotes a corrosive fiber, and the fiber 12 is pressurized to a certain thickness in advance and formed into a mat shape. Reference numeral 13 denotes a net attached to one surface of the fiber 12 with an adhesive, and the net 13 has an eye for germinating and growing plant seeds. Then, the mat 14 having a certain thickness is formed by sticking the fibers 12 and the net 13 together.

[0004] The seeding substrate 20 is formed by a flow operation, and 15 is a seed adhered on the mat 14. Then, the seeds 15 are attached on the mat 14 at a rate of 5 to 7 g per m ² . 16 is this seed 15
And a hopper for spraying a predetermined amount of the hopper, and an opening 16 formed at the lower end of the hopper 16.
The amount of seeds 15 to be sprayed is adjusted according to the size d of a.

A sprayer 17 sprays a water-soluble adhesive 18 for bonding the seed 15 to the fiber 12. That is, the seeds 20 sprayed on the mat 14 have the adhesive 1
8 fixed on the mat 14.

[0006]

However, when the seeding substrate 20 is formed by the above-mentioned conventional method, it is necessary to select the seeds 15 of the plant to be seeded. In other words, as the seeds 15, plants 15 with hair, such as Japanese pampas grass and Chigaya,
A feathered seed 15 such as a knotweed is used (in this specification, the fluff and feather of a plant seed are called fluff, and the seed on which the fluff or feather is formed is called fluffed seed). In this case, even if the seeds 15 were to be stuck on the mat 14 evenly, the seeds 15 were inevitably clumped, and the adhesion of the seeds 15 was uneven.

That is, when the opening 16a is made small, the fluffed seeds 15 are entangled with each other and do not fall off at all, while when the opening 16a is made large, a large number of Since 15 dropped at once, unevenness occurred, and it was impossible to uniformly spray at a predetermined density.

In order to solve such inconvenience, a method of removing the fluff of the seed 15 in advance is conceivable. However, in this case, not only an extremely complicated operation is required, but also the removal of the fluff. It is possible that the germ, which is the most important tissue of the seed 15, is destroyed, which may cause poor germination.

The present invention has been made in view of such circumstances, and is a fluffy seed that is uniformly dispersed without being clumped and held, despite being a fluffy seed. And a method for producing the same.

[0010]

Means for Solving the Problems The seeding substrate for fluffed seeds of the present invention, which has achieved the above object, comprises a cotton-like fiber and fluffy seed mixed and dispersed in the fiber. It is formed in a shape. In other words, the seeds are not scattered on the mat but are dispersed in a state of being mixed with the fiber, so even though the seed type has fluff, it can be sown evenly at a certain rate. It becomes possible.

Further, by providing a net attached to one side with an adhesive and cutting the net to a predetermined length, the seeding substrate can be more easily handled. In addition, by using the fiber as a corrosive material, the seeding substrate is corroded and disintegrated, and the seeds provided on the seed are easy to germinate and grow, and it is also desirable that the residue is not left on the construction site. That is.

Further, as a method for producing a seeding substrate for fluffy seeds, fluffy seeds can be mixed and dispersed in flocculent fibers and then pressed to form a mat. And after shaping | molding into a mat shape, while sticking a net | mesh body with an adhesive agent and cutting to a fixed length, an easy-to-handle seeding base can be manufactured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 3 show an example of a sowing substrate for fluffed seeds of the present invention and a method for producing the same.
In these figures, reference numeral 1 denotes a sowing substrate, and the sowing substrate 1 is a mat 4 formed by mixing and dispersing flocculent fibers 2 with fluffy seeds 3, and is adhered to the surface of the mat 4. And a net 5.

The flocculent fiber 2 is, for example, corrugated cotton, which is a corrosive material. As an example of the fluffy seeds 3, the lump of the corrugated cotton, such as Japanese cedar, scotch, and knotweed, are added at a rate of 5 to 7 g / m ³ in advance. It is mixed. In this example, by using corrugated cotton as an example of the fiber 2, after laying the seeding substrate 1, the fiber 2 is gradually corroded and collapsed,
The seeds mixed into the fiber 2 are easy to germinate and grow, and the residue is reduced after growing the plant. Note that the cotton-like fiber 2 may be formed of a water-soluble fiber. Further, a corrosion-resistant fiber such as polyester may be used.

Reference numeral 6 denotes a means for mixing the fluffy seeds 2 with the fluffy seeds 3 while forming them into sheets, and forming them into a shape.

Next, a net 5 made of synthetic resin thread having a size of, for example, 5 to 30 mm is attached to the surface of the mixed cotton wool 2 and fluffy seeds 3. At this time, a pair of rollers 8 for applying the adhesive 7 to the net 5 is provided, and for example, the water-soluble adhesive 7 is supplied to one of the rollers 8. In addition, the net 5 of the present invention is not limited to the above-mentioned one, and any net 5 having an eye for enabling germination and growth of plant seeds can be used.

In this embodiment, since the net 5 and the cotton wool 2 are bonded by the water-soluble adhesive 7, the connection between the net 5 and the cotton wool 2 is established after the seeding substrate 1 is installed. The seeds that are gradually released and mixed with the soft cotton 2 become easy to adjust to the slope. Needless to say, the present invention is not limited to making the adhesive 7 water-soluble.

Reference numeral 9 denotes a pair of pressure rollers. The pressure roller 9 causes the mixed cotton wool 2 and fluffy seeds 3 to be mixed.
The net 5 is pressed in a state of being along the surface of the above, and the net 5 is stuck to the surface of the cotton wool 2 to form a mat 4 composed of the cotton wool 2 and the seeds 3 with fluff. And mat 4
The net-like fibers 2, fluffy seeds 3, and net 5 formed on the seeding substrate 1 are cut at a point A shown in the figure.

FIG. 2 is a perspective view showing the structure of the completed seeding substrate 1, showing a state where a part of the net 5 has been peeled off from the mat 4. By cutting the seeding substrate 1 into a fixed size as in this example, management during construction and transportation is facilitated, and workability is improved. The seeding substrate 1 may be made long and rolled up in a roll shape.

FIG. 3 is a longitudinal sectional view showing a state in which the seeding substrate 1 is used for greening, for example, a slope 10 of a hillside or a river embankment or a slope 10 formed along with road construction or land development. FIG. In FIG. 3, the seeding substrate 1 is fixed to the slope 10 by the anchor 11 so that the slope 1
It does not fall from zero.

As described above, according to the present invention, the seeds 3 are mixed with the cotton-like fiber such as the cotton wool 2 and dispersed to form the mat 4, so that the seeds 3 are fluffy seeds. Even so, the seeds can be uniformly mixed with a certain distribution. In this example, as an example of the fluffed seeds, Japanese pampas grass, scotch, and knotweed are illustrated, but the present invention is not limited to this, and it goes without saying that other fluffed seeds such as dandelion and maple are also used. No. Further, a water retention material such as vermiculite or perlite, or a compost such as a general chemical fertilizer or bark compost may be mixed with the seed 3.

In this embodiment, the net 5 is adhered in order to increase the strength of the mat 4. However, the present invention is not limited to providing the net 5, but the fluff 2 The seed 2 may be formed by mixing the seeds 2 with the seeds. Further, when the net 5 is provided, the net 5 is not limited to being attached to the upper surface of the mat 4, but may be provided on the lower surface of the mat 4,
It may be interposed between the mats 4.
