The present invention relates to a construction method using environmentally friendly green soil composition and environmentally friendly green soil composition using environmentally friendly materials.

As the slope greening works in Korea have no standards for design and construction suitable for our situation, they are only supplying early recording and are mainly built on exotic grasses (sheep grass). By indiscriminately applying the greening method without analyzing the ecological environment of the damaged slopes, most of the planting plants are killed within two to three years, and the slopes are re-ravaged. Moreover, exotic grass species (sheep grasses) for slope greening may spread to the surrounding ecosystem, and if they are too dominant, they will interfere with the natural invasion of surrounding vegetation, and if they are not suitable for Korea's climate, they will be naturally selected within a few years. Is needed.

In addition, the main material of the dry method, which is one of the existing sloped greening methods, is a method of spraying vegetation base materials with air using sewage, pulp sludge, etc., which processed industrial waste, and the material is grown after plant growth. Rather, there is a case of conveying, there are a number of problems with the dry method after construction and the fallout due to the self-weight of the artificial soil thickness, plant tests appearing within 2-3 years and the resulting artificial soil flow down.

In this regard, the green soil construction method has been attempted as a greening method for artificially creating an environment in which plants can grow on the soil incision surface as an environmentally friendly method. The rust soil earth method is a construction method that creates artificial conditions for plants to grow naturally by spraying the rust soil soil produced 1 to 10 ㎝ thickness so that the moisture retention is good and contains a large amount of nutrients. Therefore, in the application of the rust soil method, it is necessary to avoid the greening method that focuses on the exotic grass species (sheep grass) in order to meet the restoration target considering the natural environment in the future, to secure the stability of the slopes damaged by the construction, and to consider the surrounding natural environment. There is a need to improve aesthetics and scenery, to create a stable vegetation that is consistently stable, and to have a vegetation structure that is beneficial for carbon dioxide reduction.

The present invention is to grow the ground and underground parts of the plant planted on the slope using eco-friendly materials uniformly, to improve the binding force, moisturizing power and breathability, and to increase the adhesion of green plants, erosion resistance of the soil successfully and efficiently on the slope The challenge is to provide an eco-friendly green soil composition that can create stable vegetation by greening.

Figure 4 is a 2.5 months after the construction using the green soil composition according to the comparative example of the present invention (However, ① silk tree, ② sari, ③ non-repair).

Hereinafter, the present invention will be described in detail.

In one aspect, the present invention increases the strength and adhesion of the material in consideration of physical properties, and at the same time serves to prevent peeling and loss of cancer slopes, and to increase the growth of the bore, the moisturizing power, and the air permeability of the plant to increase the growth of the ground and the underground. In addition, the present invention relates to an environment-friendly green soil composition for providing a material that can be applied to a slope greening method which is economical and efficient in terms of recycling resources, and continuously creates stable vegetation.

The present green rust soil composition comprises 30 to 50 parts by weight of soil powder, 30 to 45 parts by weight of earthworm fecal soil, 5 to 15 parts by weight of bark compost, 5 to 15 parts by weight of phage crushed powder and 5 to 25 parts by weight of coco peat. And, it is characterized in that it comprises 0.0001 to 0.01 parts by weight of microorganisms, 0.005 to 0.1 parts by weight of chitosan and 0.1 to 1 parts by weight of soil stabilizer as a trace component.

The content of soil in the main component is preferably 30 to 50 parts by weight. When the content of soil powder is less than 30 parts by weight, the porosity decreases, the cracking rate increases, the germination rate decreases, and when the content of soil content exceeds 50 parts by weight, unfavorable phenomenon occurs due to excessive organic content. It is not preferable because the specific gravity is high because the phenomenon of deterioration of adhesion force and strength that would be applied to the surface of the coating occurs. More preferably, the soil powder may be selected from basalt weathered soil to increase air permeability.

In addition, the earthworm fecal soil of the main component is made of a stable material by the earthworm ingested the organic waste which is the main culprit of environmental pollution by using the earthworm, which is very high in nitrogen and carbon constituting the plant body, calcium, magnesium, potassium It is also rich in inorganic nutrients such as sodium and manganese. In particular, as they pass through the body of the earthworm, inorganic nutrients become water soluble so that plants can easily absorb them. And the earthworm feces form is formed in a grain structure. Earthworms that eat organic matter improve soil physical properties, such as fecal soils that come together to improve water drainage, retention, and retention. This is because the grains stick together strongly as the earthworm goes through the body and the water resistance is high. In addition, the pores formed by the herd structure make it easy for plant roots to extend and increase the fertility of the soil by increasing aerobic microorganisms. These results may be due to the oversupply of nutrients from earthworm feces.

Earthworm fecal content is preferably 30 to 45% by weight. If the content of the earthworm fecal soil is less than 30% by weight, it is not preferable because the effect of the earthworm fecal soil is insignificant.If the content of the earthworm fecal soil is more than 40% by weight, even if the earthworm fecal soil has sufficient nutrition for plants, sometimes high concentrations of Na + and other salts This is undesirable because it is abundant and can harm plants.

In addition, the bark compost of the main component is the bark and pine and other deciduous trees that are wastes generated during the production process of the wood to recover the compost, it has abundant moisture retention capacity and air permeability, the base substitution capacity is large The soil is not hardened, and after it is completely dried, it forms a structure that easily receives moisture, promotes the growth of soil microorganisms, in particular, tannin acid contained in the bark removes harmful phytopathogens, and more than 50% moisture It has a very beneficial role in early germination. When the bark compost is included in less than 5 parts by weight, its effect is insignificant, and if it exceeds 15 parts by weight, there is a risk of loss of green soil, so it is preferable to include 5 to 15 parts by weight since it is hardly helpful for the sliding of green plants. Do.

In addition, the phage pulverized product of the main component is a fine fiber cellulose is the main component, the cellulose has an excellent moisture absorption and moisturizing power, the organic content of more than 36% plays an important role in plant growth. In particular, it helps mulching effect and water retention during seed germination, and prevents soil erosion due to rainfall by maintaining a certain hardness when drying, as well as other fibers that are mixed together due to the large specific surface area of the fine fiber. The composition can be held between fibers to minimize the loss of material due to rainfall and the like. Less than 5 parts by weight of the phage crushed product has a negligible effect such as lowering the cohesive strength of the green soil, and if it exceeds 15 parts by weight, the hardness of drying is increased and there is a problem of cracking of the growth base material due to shrinkage and expansion. It is not preferable because it will adversely affect the growth of grass and wood.

In addition, Cocopite among the main components is an organic component extracted from the portion of the Husk portion of the natural coconut fruit, which is an inert fiber component such as ligline and cellulose, but also contains significant organic nutrients (67%) and trace elements. , Repair, bobbin, ventilation, absorbency is excellent. In particular, it has excellent moisture retention ability, so it has a high moisturizing effect that retains moisture for a long time even in dry and dry climates, and it is composed of neutralizing substances that fix soil acidity between 5.7 ~ 6.8, preventing soil acidification.

The content of these cocoites is less than 5 parts by weight, and if the content is greater than 25 parts by weight, the organic content is high, which is not preferable because the malnutrition and gas disturbance adversely affect the germination of plants and the growth of plants. .

In addition, microorganisms in trace components promote direct and indirect action to decompose various organic substances in the soil, thereby improving the physical and chemical properties of the soil, promoting the growth of crops by promoting soil granulation, and the basics of crop production. Serves to make the soil healthy. Preferably, in the present invention, by including bacteria that can solubilize phosphoric acid and insoluble nutrients, it is possible to decompose organic matters and contribute to the uniform growth of crops. More preferably, one or more microorganisms may be selected from the genus Aspergillus, Rizopus, Lactobacillus, and Bacillus, and the microorganism of the genus Aspergillus is most preferably Aspergillus niger (KACC 93025). The Aspergillus niger (KACC 93025) can decompose poorly soluble phosphate in the soil to free phosphate to solve the crop cultivation disorder due to salts in which poorly soluble phosphate accumulates, which is included in the main ingredient material Decomposes the salt.

In addition, the microorganisms shown in Table 1 can be selected as the microorganisms.

In addition, the microorganism is preferably to include 0.0001 to 0.01 parts by weight. If it is contained less than 0.0001 parts by weight, the lack of microorganisms is hardly conducive to the vegetation environment. If it is more than 0.01 parts by weight, decomposition of organic matter proceeds too fast, resulting in loss of nutrients and production costs. There is this.

In addition, chitosan, a trace component, is a 3,000 to 5,000 glucosamine-linked polymer. It is a substance obtained from shellfish and chitin or shellfish. It activates callus formation, increases root development, and promotes growth and increase of plant growth. Will be promoted. In addition, it acts as a plant pest control agent, proliferates the soil actinomycetes and contributes to the formation of swarm structure, which not only has a soil improvement effect, but also increases fertilizer absorption rate when plant cells are activated by chitosan.

Preferably, the chitosan has a viscosity of 1 to 100, and it is preferable to use those having an appropriate molecular weight of tens of thousands to hundreds of thousands, and when the amount is less than 0.005 parts by weight, the effect is insignificant. It is preferable to include 0.005 to 0.1 parts by weight because it may grow over or cause damage.

Preferably, the soil stabilizer is a biodegradable soil stabilizer, characterized in that the T / C (Terra-control) ™ having the ability to fix the seed and inhibit the water evaporation of the soil. The soil stabilizer serves to prevent soil erosion by wind and rainfall, to protect seeds and plants, to extend the moisture content in the soil, and to protect the soil and vegetation from excessive dehydration or drying. In this case, when the soil stabilizer is included in less than 0.1 part by weight, there is a problem that the soil is hardened and cracks occur when the soil is dried, and when used in excess of 1 part by weight, the soil stabilizer may adversely affect plant growth. It can be generated within the above range so as not to adversely affect the growth of the plant while providing sufficient corrosion resistance between the erosion and rain particles due to rainfall.

In another aspect, the present invention relates to a construction method using an eco-friendly rust soil composition comprising the step of spraying the eco-friendly rust soil composition on the slope.

 Preferably, in the construction method of the present invention, before the step of spraying the rust soil composition, anchor the mesh cover such as a metal coated iron or PVC coated net which is a mesh of synthetic resin on the soil rock incision surface. Fixing with a fixing means such as may be further included. Preferably a PVC coating network is used. The step of covering the PVC coating network is necessary when the rock of the soil incision surface is not stable and there is a possibility that the rock is lost, the eco-friendly chlorophyll composition is to improve the adhesion of the soil incision surface.

In addition, in the present invention, before the step of spraying the eco-friendly green soil composition, the eco-friendly green soil composition may further include supplying water so that the water content is 35 to 50% to adjust the water content of the eco-friendly green soil composition. . This water content control step is to facilitate the germination and growth of plants and to increase the adhesion to the soil rock incision surface of the environment-friendly green soil composition.

In addition, in the present invention, the construction thickness in the step of spraying the environment-friendly rust soil composition may be made in the range of 1cm to 10cm. If it is less than 1cm may be eroded by rain, etc., if it exceeds 10cm may be lost due to the weight of the soil and construction may be difficult.

In addition, in the present invention, the step of mixing the seeds of the grass, wildflowers and plants in the eco-friendly green soil composition before the step of spraying the eco-friendly green soil composition, or after the step of spraying the eco-friendly green soil composition, seeds of the grass, wildflowers, etc. Spraying may be further included.

Hereinafter, the present invention will be described in detail with reference to Examples, but the scope of the present invention is not limited thereto.
