Hereinafter, preferred embodiments of the present invention will be described in detail. In the following description, numerous specific details, such as specific elements, are set forth in order to provide a thorough understanding of the present invention, and it is to be understood that the present invention may be practiced without these specific details, It will be obvious to those who have knowledge of. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The mixed soil for slate surface greening according to the present invention is characterized in that it contains 12.5 to 300 parts by weight of loess, 12.5 to 300 parts by weight of mossaite, 12.5 to 300 parts by weight of coco peat, 5 to 150 parts by weight of zeolite, 95 to 99.5% by weight of a host material comprising 2.5 to 100 parts by weight of a charcoal powder, 2.5 to 20 parts by weight of a hygroscopic polymer, and 2.5 to 20 parts by weight of a fermented starch fraction; From 0.3 to 4% by weight of a binder comprising from 5 to 1000 parts by weight of a cellulose powder and from 5 to 1000 parts by weight of an acrylamide per 100 parts by weight of sodium silicate; And 0.1 to 2% by weight of a promoter comprising 20 to 100 parts by weight of moss and 10 to 100 parts by weight of polyvinyl alcohol per 100 parts by weight of water.

First, wood crushing powders constituting the main constituent are obtained by crushing the forest waste generated at the construction site. Two types of crushed wood crushing powders are used: one is crushing several logs of normal forests and the other is crushing crustaceans having many corrosive acids. When the shredded material is mixed with the recording material, it strengthens the bonding force of the material in the formed foundation, and it has the function of promoting the growth of the tree and activating the growth of the plant by favoring the propagation of the soil microorganism with good ventilation do. If the content of the wood crushed powder is less than the above range, the growth of plants including trees will be lowered. On the other hand, if the content exceeds the above range, the hardness of the soil will increase and the plant growth will be decreased and the nutrients in the soil will be decreased. Particularly, there is a large amount of microorganisms in root milling pulp than in the canola. Among them, aerobic bacteria (oxygen bacteria) oxidize and decompose nutrients by using free oxygen in the air and use energy generated at that time. This action of aerobic bacteria plays an important role in helping plant oxygen breathing and providing microorganisms favorable to plant growth.

Masato and loess serve as the backbone of the plant's growth-based materials and play an important role in the formation of complex structures of intergranular particles. In particular, the metal components including calcium chloride in the loess component are combined with the water-soluble silicic acid to cause the coagulation and hardening of the base material, thereby increasing the adhesion between the materials. If the ratio is less than the above range, the drainage performance is deteriorated. On the other hand, if the ratio exceeds the above range, the binding force between the materials is lowered. If the amount of the loess is less than the above range, it is difficult to sufficiently manifest the above-mentioned adhesive force. Conversely, if the loess exceeds the above range, the amount of oxygen supplied to the plant is reduced. The characteristics and main components of the mashito are shown in Table 1, and the main components and characteristics of the loess are shown in Table 2 below.

Absorption Rate (%) Unit solute weight (kg / l) Porosity SiO ₂ Fe ₂ O ₃ Al ₂ O ₃ CaO MgO 4.2 1.5 to 1.8 28-38 98 1.9 0.3 to 0.6 0.02 to 0.05 0.4

Coco peat is chemically an inert fibrous component such as lignin and cellulose, and contains significant organic nutrients and trace elements. Physically, it promotes plant growth with good water holding capacity, bending strength and breathability. When the content of coco peat is less than the above range, the plant growth is deteriorated, and when the content exceeds the above range, the bonding force between the materials is deteriorated.

The zeolite is a silicate hydrate such as aluminum, sodium, calcium and the like, and has a cation which can be easily exchanged such as sodium or potassium ion, so that calcium or magnesium in the water is substituted with an ion, and as a result, the water softens. And, since it has a relatively large space in the inside, the adsorbing power is excellent, and therefore, it has excellent water retention capacity and brittleness preventing abrupt change in concentration of fertilizer component. If the content of the zeolite is less than the above range, the bubbling power and the moisturizing power deteriorate and the water supply is reduced. On the other hand, if the content exceeds the above range, the water substitution period becomes long and may be decayed.

The bone meal is powdered bone of an animal or shell of a shell, and serves to supply inorganic nutrients necessary for the growth of moss.

The charcoal powder has a surface area as large as 300 square meters per 1 g, so that the ability to absorb water is superior. If the air humidity is more than 60% in the case of a dryer, the charcoal powder sucks the moisture in the air and supplies the water to the plant roots It also absorbs moisture and nutrients and has a function of gradually releasing it. It also has a germicidal effect, which also acts to kill germs harmful to plants. When the charcoal powder having such properties is used for the soil, the physical properties of the soil are improved, and the microorganisms useful for the chemical effect through the neutralization of the soil acidity and the adsorption and preservation of the inorganic nutrients are increased. If the content of the charcoal powder is less than the above range, the water absorption capacity of the vegetation material is lowered. On the other hand, if the content exceeds the above range, the bonding force between the materials deteriorates. In particular, charcoal powder or pine charcoal powder is preferably used in the present invention, and characteristics and main components of these charcoal powders are shown in Table 4 below.

pH T-N (%) P ₂ O ₅ (%) K ₂ O (%) CaO (%) MgO (%) Na (%) Charcoal powder 9.7 0.71 2.45 0.86 1.81 0.26 0.69 Pine charcoal powder 9.2 0.15 0.12 0.2 0.4 0.08 0.13

The hygroscopic polymer allows the mixed soil of the present invention to absorb water and keeps the water well even on a sloped slope so that water supply can at least allow the plant to grow and the hardness of the mixed soil can be maintained appropriately to allow flexible plant growth . The hygroscopic polymer can be used without limitation as long as it is used in related fields. For example, polysulfonic acid can be used. If the content of the hygroscopic polymer is less than the above range, the above-mentioned effect can not be expected. On the contrary, if the content exceeds the above range, the binding force between components constituting the mixed soil is weakened.

The fermentation product obtained by removing the toxic substance from the fermentation product selected from the group consisting of milk, poultry, and flour is improved to improve the water retention and physical properties of the soil, and it is more preferable to carry out an aging period after fermentation. And it contains a large amount of organic matter, nitrogen, phosphoric acid, etc., so it is an important sustainable fertilizer that is indispensable for the growth of plants. It also helps microbial propagation and contains many microorganisms in itself. If the content of the fermentation product is less than the above range, the growth of the plant is not sufficiently achieved. Conversely, if the content exceeds the above range, it may act as a factor that hinders the growth.

Preferably, the present invention further comprises, in 100 parts by weight of the wood crushed powder, 0.5 to 20 parts by weight of an acorn powder, a dandelion powder, or an antiseptic powder and a dandelion powder.

The silk sprout results in promoting the growth of moss in the case of the present invention by uniformly supplying the nutrients not provided by general organic fertilizer to the vegetation. The above-mentioned dandelion powder is dried and powdered. Since the surface of the dandelion is negatively charged, the binding between the components constituting the mixed soil is promoted and the mixed soil is altered by the growth factors such as the sun and the temperature It prevents things.

Next, the sodium silicate composing the binder is combined with cations such as calcium oxide and magnesium oxide in the soil such as loess to solidify or cure the mixed soil of the present invention, prevent flow down when the mixed soil containing the soil is floated, Is maximized. On the other hand, it causes ettringite phenomenon on the surface of the mixed soil, which prevents the moisture of the mixed soil from being easily evaporated. If the content of sodium silicate is less than the above range, caking of the soil may be weakened and material separation phenomenon may occur. On the other hand, if the content exceeds the above range, the soil hardness may be increased due to excessive cementation, thereby lowering plant growth.

The cellulosic powder is dried by powdering the plant. Since the surface of the cellulose powder is negatively charged, it promotes the bonding between components constituting the mixed soil and prevents the mixed soil from being deteriorated by the growth factors such as sun and temperature .

The acrylamide promotes the condensation between the components of the mixed soil so that cracks do not occur even after the mixed soil sprayed on the inclined slope surface is dried and the erosion is prevented, and the moisture and nutrients contained in the mixed soil Let's do it. In addition, the acrylamide may be used without limitation as long as it is used in related fields as moss and environmentally harmless components, for example, polyacrylamide can be used.

The moss constituting the promoter of the present invention may be selected from the group consisting of a moss, a gourd moss, a silk moss, a true feather moss, a feather moss, and a frost moss. Particularly, the moss is classified into a moss growing well in a high humidity region and a moss growing well in a low humidity region, and it is important to select an appropriate moss considering the humidity of a slope to which the mixed soil of the present invention is applied . Further, it is more preferable to use 1 to 50 mm of cut for uniform mixing with other components, rather than applying the entire moss.

The polyvinyl alcohol is hydrogen bonded with metal cations in the soil to promote the bonding between the components constituting the mixed soil, and the bonding with other components is facilitated through the saponification by the hydrogen bonding. Furthermore, polyvinyl alcohol is composed of only carbon, hydrogen, and oxygen, and harmful substances such as dioxin and ammonia are not generated when it is burned, so that it is an environmentally friendly material. In the mixed soil of the present invention, the polyvinyl alcohol improves the breathability and drainability and provides a favorable growth environment for moss. If the content of polyvinyl alcohol is less than the above range, the physical binding force between the materials may be deteriorated and a loss phenomenon may occur. Conversely, if the content exceeds the above range, the soil hardness may be increased and the plant growth may be reduced.

The promoter preferably further comprises 3 to 18 parts by weight of auxin, gibberellin, or auxin and gibberellin per 100 parts by weight of the water. The auxin is a substance having a structure such as indoleacetic acid, , Promotion of root formation, promotion of cell division, etc. Gibberellin is a plant hormone which has a physiological action such as promotion of growth and seed germination.

These plant hormones promote germination and growth of the moss, thus enabling the slope with the mixed soil of the present invention to be quickly recorded. In the present invention, when the content of plant hormones such as auxin or gibberellin is less than the above range, greening due to moss is delayed. On the contrary, if it exceeds the above range, ethylene or the like which inhibits the growth of moss is synthesized.

The water constituting the promoter may be ordinary water, but it is more preferable to use triglyceride, which is a supernatant liquid obtained by adding and mixing yellow soil or the like and then precipitating and retaining solid content. The above-mentioned nigiri is sufficiently contained with various inorganic nutrients such as metal ions for promoting the growth of moss, thereby enabling the mixed soil of the present invention to videotape quickly.

On the other hand, the slope surface greening method of the present invention comprises a step of preparing a promoter mixture, a step of preparing a main mixture, a step of producing a binder mixture, a step of producing mixed soil of the present invention, and a slope surface spraying step.

First, a mixture of 100 parts by weight of water and 10 to 100 parts by weight of polyvinyl alcohol is immersed in 20-100 parts by weight of pre-dried moss to prepare a promoter mixture constituting the present invention.

Then, 100 parts by weight of the crushed wood powder, 12.5 to 300 parts by weight of loess, 12.5 to 300 parts by weight of matsato, 12.5 to 300 parts by weight of cocofit, 5 to 150 parts by weight of zeolite, 2.5 to 100 parts by weight of bone powder, 40 to 70% by weight of a host material containing 2.5 to 20 parts by weight of a fermented starch, and 30 to 60% by weight of water are mixed in a first mixing tank to prepare a master mixture.

The promoter mixture as much as 0.0005 to 0.004 times the weight of the host mixture is added to the host mixture and mixed.

Separately, 7 to 15% by weight of a binding material comprising 100 parts by weight of sodium silicate, 5 to 1000 parts by weight of cellulose powder and 5 to 1000 parts by weight of acrylamide and 85 to 93% by weight of water are mixed in a second mixing tank, A mixture is prepared.

The slope surface recording method of the present invention is completed by spraying 92 to 95% by weight of the main mixture and the promoter mixture sent out from the first mixing tank and 5 to 8% by weight of the binder mixture sent out from the second mixing tank together .

In addition, the slope-side greenery method of the present invention may further comprise mixing the host material mixture and the promoter material mixture with the binder mixture before spraying on the slope surface.

The mixed soil of the present invention can be applied to artificial structures such as cut surfaces (eg, rock), retaining walls, bridges, soundproof walls, median separators, building walls, and rooftops to be recorded through hydraulic injection attachment. In addition, it can also be applied to interior wall parts of small units, stone materials, bricks, other materials that require moss recording, and manpower by spraying.

The greening composition applied by a hydraulic attachment device, a spray or a brush or the like changes the mounting thickness to about 0.5 to 7 cm depending on the site. For example, the cut rock mass should have a thickness of 3 to 7 cm since the residence time of the gravitational force is short and the ground can not hold moisture. However, if it can be managed at a certain time (1 ~ 2 times / 1 day / 3 months) until the initial recording by the automatic water management system (for example, irrigation system) cm to reduce material costs. Moss vignetting is the most important time to increase the density of moss through spore activation in the first 3 months immediately after construction. Sufficient management and monitoring can lead to high quality moss vignetting.

Hereinafter, embodiments of the present invention will be described.
