Abstract

PURPOSE:To improve the fixing ratio of vegetation, and to prevent the breaking of an ecosystem by using carriers, in which vegetable fibers having a specified diameter or more are formed in a three-dimensional meshy shape, plant seeds and fertilizers as main components and forming the components in a sheet or mat shape having specific percentage voids or more and specified thickness. CONSTITUTION:Natural vegetable fibers having a diameter of 0.1mm or more are formed in a three-dimensional meshy shape including a large number of voids 1, and employed as carriers 2. Plant seeds 3 and fertilizers 4 are attached to the carriers 2 or the carriers 2 are impregnated with the seeds 3 and the fertilizers 4, and the wholes are used as main components, and formed in a sheet or mat shape having percentage voids of 50% or more and thickness of 3-30mm. When the voids 1 are filled with fine soil at the time of the execution of works, water permeability, light transmission properties, ventilation, nutrient, etc., required for a plant are ensured. Accordingly, a fixing ratio is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation mat required for a wide range of greening projects on roadsides, dikes and other cut slopes, golf courses and the like.

[0002]

2. Description of the Related Art Spraying by spraying a slurry-like culture soil mixed with seeds, fertilizers, etc. in advance on the surface of slopes (via net etc.) with a compression pump in slope protection such as roadsides and other greening projects Construction method, non-woven fabric, paper, cotton, or some kind of lichen grass charcoal, etc. (seed and fertilizer) is attached (mixed) into a sheet with a net, straw, etc., if necessary, on the surface of the slope etc. 2. Description of the Related Art A sheet construction method for laying a bamboo or iron skewer for germination, a sandbag construction method for laying a sandbag made of such sheets into a bag and sprouting on the surface thereof, and the like have been conventionally known.

[0003]

In the various conventional construction methods as described above, since the seeds generally flow due to rainwater or the slope is broken and the buds are hard to sprout and roots are hard to be established, the fixing rate is 1 It is said to be / 4 to 1/5, and the cost is high for those devised to improve this, and the problem of destroying the natural ecology due to the inclusion of plastics and synthetic chemicals. In addition, there are drawbacks such as weakness against pests and pathogenic bacteria. An object of the present invention is to solve these problems.

[0004]

[Means for Solving the Problems] As a result of various experiments and researches for solving the above problems, for example, hemp, pulp,
Natural plant fibers such as corn, coconut, banana, sugar cane and the like having a thickness of 0.1 mm or more are mainly used to form a three-dimensional mesh containing abundant voids (1) and form this into a carrier (2 3) and a plant seed (3) and fertilizers (4) are attached to, attached to or impregnated with the plant seed (3) to be a main constituent and have a porosity of 50% or more.
It was found that a sheet or mat having a size of about m can be a very desirable material for vegetation (greening) in both the spraying method and the sheet method.

That is, in the present invention, the carrier (2) used is a natural vegetable fiber, and at the same time, its thickness is rough with a diameter of 0.1 mm or more, and it has a great porosity. It has a remarkable feature that it has a large three-dimensional structure.

However, since the above numerical values and components describe the characteristics of the entire mat as a product, it goes without saying that some elements that do not correspond to them may be included, and the carrier (2) is also included. May also serve as fertilizer (4).

Further, a pest repellent material (5) different from the insecticide is attached to the carrier (2) (absolute amount does not matter).
Due to the structure of the mat of the present invention, the main constituents have a high insect repellent effect even after vegetation, as will be described later.

[0008]

In the present invention, a coarse plant fiber having a thickness of 0.1 mm or more is used as a skeleton to form a three-dimensional mesh mat having a porosity of 50% or more, and a fine soil (6) is formed in the void during the construction. Since it was filled, it was found that the water permeability, translucency, ventilation and nutrients required for the plant were secured, so that the plant was easy to germinate and the rooting was improved, and the fixing rate thereof reached 90%.

Further, the topsoil having a structure in which the fine soil (6) is contained in the voids (1) which are abundantly contained in the three-dimensional mesh structure mat is formed, so to speak, with the topsoil layer containing the reinforcing material. Since it is so robust that it does not easily collapse or flow due to rainwater or mudflow, it not only makes it difficult for seeds and fertilizers to flow out, but also prevents slopes and landslides due to wind and rain ( It was also found to be useful for slope protection), but this also contributes to the above-mentioned high retention rate and growth.

Furthermore, since the main material consists entirely of natural plant fiber, the base begins to rot when the plant just takes root, and it returns to the soil to nourish the plant, so that it follows the natural circulation system (ecology). Will be things.

Further, since the elution rate of fertilizer or the like adhered to or impregnated in the base carrier can be adjusted by a binder or the like, it can be adapted to the growth of plants, but this also makes it difficult to generate mud or water flow. It can be realized by doing so.

When the carrier (2) is adhered or impregnated with the pest repellent (5), it becomes a constituent of the topsoil and gradually diffuses even after the growth of the plant. It was also found that the insect repellent effect can be maintained throughout.

Furthermore, the vitality of the desired plant is strengthened by these, and the roots are firmly rooted, so that it also has the function of suppressing the growth of harmful fungi and weeds. It will form a hard and hard slope.

[0014]

Example 1 Coconut fiber having an average diameter of 0.3 mm was used as a carrier (2), which was used together with a starch binder (including essential nutrients, growth promoters, etc. as fertilizers (4)) and turf seeds (3). 10m containing the void (1) as shown in Fig. 1
It is formed into a three-dimensional mat having a thickness of 1,000 m and a width of 1,000 mm.

To carry out construction using this, first, a slope is formed by cutting soil or the like, and the sheet is stuck on the slope and fixed with a bamboo skewer. Sprinkle fine soil (6) on it and lightly dust it as shown in FIG.

As a result, as described in the section "Operation," the result was extremely good and a high fixing rate was exhibited.

[0017]

Example 2 A pest repellent material (5) was previously added to the same carrier (2).
(Product name Eco Green, made by Nippon Mining Industry KK), impregnated with a mat in the same manner as above, and then applied, the pests do not approach the plant for a long period of time, and there is no disease, and a very good vegetation state can be maintained. Became.

[0018]

As described above, according to the present invention, the fixing rate of vegetation can be remarkably improved, and at the same time, a strong surface soil layer can be formed to protect slopes (prevention of disasters), and waste of materials can be avoided. At the same time, all the materials are returned to nature and recycled without destroying the ecosystem, and it is possible to prevent pests and pathogenic bacteria without using harmful pesticides, which is very healthy and economical. There is.
