In the present invention, the plant composition for planting greenery fixed to the surface fixing material through the pulp may be replaced by such elements, since the seeds are universal, but the plants may be cut and propagated or the roots are propagated. You may mix and use. Hereinafter, for convenience, the seed will be described as an example.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

The present invention has a main feature as using the conventional soil erosion prevention mat as filament forming a three-dimensional network structure similar to the root of the plant as the surface fixing material (1) and the network structure is a three-dimensional structure formed with irregularities. As described above with reference to Figure 1, the conventional soil erosion prevention mat (1) is a synthetic resin melt-extruded through the radiator 30 on the egg plate-shaped transfer belt 20 is formed with irregularities proceeding while oscillating from side to side As the filament is scattered, seated on the belt, cooled, and then separated and wound on the belt, the conventional soil erosion prevention mat 1 manufactured as described above has a three-dimensional structure in which the filament resembles the root of a plant as shown in FIG. It forms a network structure, and the network structure forms a three-dimensional shape with irregularities, and is excellent in flexibility and tensile property.

After fixing the surface of the three-dimensional structure (1) acts as a topsoil layer to protect the surface of the soil after it is fixed to the surface to prevent the seed or young plants from blowing in the wind or washed down with water, and also grown here When the plant is rooted, the plant and the mat naturally combine to act to strengthen the root fixation.

The surface fixing material (1) is particularly excellent in flexibility and tensile force because it becomes a three-dimensional three-dimensional plant root structure. Synthetic resin is used as the material of the surface fixing material (1), it is particularly advantageous to use the biodegradable synthetic resin can see the effect that can solve the environmental pollution problem.

According to the present invention, the mixture of the pulp 2 and at least one selected from the group consisting of the seed 3, the stem and the root is attached to the surface fixing material 1.

Pulp (2) is a collection of cellulose fibers obtained by mechanical, chemical, or intermediate methods from wood or other fiber plantings. Originally, the pulp contains a lot of moisture, and thus, the pulp is dehydrated by a method such as pressing or the like. It refers to wet matter, which means the extract and gathering the fibers that make up the plant. In general, the pulp (2) is classified after the production method or raw material.

The raw materials are classified into wood pulp and non-wood pulp, and wood pulp is divided into softwood pulp and hardwood pulp, and non-wood pulp is straw pulp, bugassepulp, bamboo pulp, bast fiber pulp, and rag. It is divided into pulp and cotton pulp. The classification by the manufacturing method is to produce a combination of two methods, mechanical pulp and chemical pulp first, mechanical pulp is divided into crushed wood pulp, refiner pulp, heat treatment mechanical pulp, etc., chemical pulp is sulfurous acid pulp, kraft pulp, soda pulp. Separate by. The combination of mechanical and chemical methods is divided into chemical chain pulp and semikeky pulp.

According to the present invention, all of these kinds of pulp can be used, but it is effective to select among them those components which do not inhibit the growth or germination of seeds.

It is preferable to select the seed 3 which can grow well in the place where this mat is installed. For example, when installing in water, it is preferable to select plant seeds, such as reeds, which can root and grow in water.

The pulp-seed mixture coated on the surface protection material 1 according to the present invention can be added with trace additives such as antioxidants, anti-corrosion agents, colorants, etc., or fertilizers that help plant growth, and also include sawdust, chaff, etc. Artificial soil may also be blended. A consideration in selecting these additives is whether or not it adversely affects plant growth.

Figure 5 shows a state in which the mat of the present invention is installed in the soil layer. As shown, the surface protection material (1) has a three-dimensional three-dimensional plant root structure so that even if the mat is installed in the soil and placed under environmental influences such as rain, wind or soil erosion, the seed (2) and pulp ( 3) is not lost and is formed inside the inverted pyramid-shaped structure (the pocket of the structure 0, such as the groove shape of the transfer beet) formed in the front protective material (1) can ensure a safe vegetation.

In addition, the plant root shape network of the legal protective material (1) grows in the legal protective material (1) to continuously strengthen the fixation of the roots of the plant falling on the soil, and protect the upper soil against erosion, thereby smoothing the growth of the plant. To provide the effect.

In addition, the mat of the present invention has the advantages of easy construction, minimizing the cost of artificial earth production, excellent thermal and moisturizing effect, and can be applied to underwater, wetlands, low and high lakes.

Hereinafter, the method for manufacturing the mat of the present invention described above will be described.

According to one preferred embodiment of the present invention, pulp and seed in the form of slurry are first introduced under stirring in a stirring vessel equipped with a bubble generator, and bubbles are supplied from the bottom of the mixture into the mixture.

At this time, since the bubbles supplied in the mixture are deflected by stirring, it is effective to appropriately adjust the supply flow rate and the stirring speed of the bubbles so that the bubbles remain in the mixture. Bubbles are present in the pulp-seed mixture thus mixed, and it is easy to apply to the surface fixing material (1).

Next, when the surface fixing material 1 coated with the pulp (2) -seed (3) mixture is dried, the microfibers of the pulp (2) hold the surface fixing material so that they are firmly bonded and the pulp (2) attached to the mat. ) Has a porosity by bubbles, and the seed (3) is surrounded by a pulp (2) of porous tissue having good ventilation and moisture retention, so even after spraying the water once after the mat (3) is germinated It keeps enough moisture to settle roots on the ground.

According to the present invention, it is also possible to use an adhesive to ensure a more secure fixation to the surface fixation material 1, which is a three-dimensional network of plant root shape of the pulp (2) -seed (3) mixture. For example, the adhesive may be formulated in the preparation of the pulp-seed mixture, or the adhesive may be pre-applied before applying the pulp-seed mixture to the surface protector, thereby increasing the binding force of the pulp-seed mixture to the frontal fixing material. .

The mat of the present invention as described above can be carried out in a single process to spread the roots by planting the mats on the sloping inclined surface around the road to plant roots therein, the surface fixing material to be a three-dimensional network of plant root shape It is possible to effectively prevent the loss of plant seeds, can be installed in water, and the pores are formed in the pulp, so that the moisture and ventilation effect is excellent.
