Description

Afforestation method using soil composition for greening slope and stabilizing

The present invention relates to a greening method using a soil mixture for greening and stabilizing slopes, and more particularly, it is possible to efficiently green and stabilize the slopes, while improving the soil to promote seed germination, and greening construction It relates to a greening method using a soil mixture for slope greening and stabilization, which suppresses subsequent sliding to promote slope greening and stabilization.

In general, if a slope that can appear at various construction or development sites is left as it is, it may impair the aesthetics, cause landslides or loss during the rainy season or thaw, and may cause human casualties.

Accordingly, in order to stably protect the slope and provide an aesthetically excellent atmosphere, as well as to restore nature, a method of artificially excavating and greening the corresponding part is being performed.

On the other hand, most of the slopes of roads, golf courses, and civil works areas where greening is performed are composed of bedrock layers or soil that is not good for plants to grow. Soil conditions in these areas are usually very unfavorable for planting due to the low depth of the soil layer, even with or without soil layer.

In addition, nutrient leaching and water retention functions are greatly reduced in the nutrient-rich topsoil and the subsoil near the topsoil, the parent material that has not undergone the transition process to the soil, and the area where the parent rock is exposed. It has inherent risks of erosion and collapse.

Therefore, it helps the growth of plants through greening construction that creates an artificial environment such as sprinkling artificial soil with excellent slope adhesion and erosion resistance so that plants can grow quickly in areas where it is difficult to cover such plants.

On the other hand, clay or artificial soil composition is essentially used in such a clay method or a greening method. Such artificial soils are variously known.

As one conventional example, Korean Patent Laid-Open No. 10-1991-0006193 discloses 10 to 30% by weight of pit, 10 to 30% by weight of briquettes, 40 to 60% by weight of sludge cake, and 10 to 20% by weight A vegetation soil composition composed of % pulp sludge has been proposed.

However, this vegetation soil composition lacks organic components such as fertilizers and does not contain charcoal powder, so it has a weak moisture retention property, which adversely affects the smooth growth of grass or vegetation, and does not contain a separate coagulant, so it slides after construction. There is a problem being

In addition, Korean Patent Laid-Open No. 10-1995-0007639 discloses 10 to 40% by weight of peat, 20 to 50% by weight of sludge cake, 20 to 40% by weight of pulp sludge, 2 to 5% by weight of sawdust and , 10 to 30% by weight of Masato, and 3 to 10% by weight of earthworm powder is proposed a clay soil composition.

However, this clay composition is rich in organic matter and is effective for vegetation of grass or vegetation, but it does not contain a soil neutralizer, so it cannot prevent soil acidification, and it does not contain a coagulant, so there is a problem in that the cohesive force is weak.

In addition, Korean Patent Publication No. 10-2001-0026503 discloses 40 to 60% by weight of raw materials for artificial soil, 10 to 20% by weight of pulp sludge, 10 to 30% by weight of sewage sludge, and 5 to 10% by weight of A green clay composition made of granite has been proposed. However, although this green clay composition is also effective for the vegetation of seeds and plants, there is a problem in that sliding occurs due to lack of cohesive force after construction because it does not contain a coagulant.

As another conventional example, in Korean Patent Registration No. 10-0419583, 3 to 5% by weight of peat, 5 to 10% by weight of raw bark, 10 to 20% by weight of livestock, 20 to 25% by weight of Masato, 2 to 2% by weight of activated carbon A green soil composition comprising 4% by weight, 15 to 25% by weight of papermaking sludge, 15 to 25% by weight of papermaking fiber, 1 to 2% by weight of carboxymethyl serolose, and 2 to 4% by weight of complex fertilizer is proposed. However, although the green soil composition is effective in cohesive and moisturizing power, there is a problem in that the reoccurrence rate is lowered due to over-maturation of seeds and vegetation due to excessive fertilizer components.

Furthermore, in Korean Patent Registration No. 10-0847087, 60% by weight of general loam, 28% by weight of humus compost, 3% by weight of vermiculite, 2.5% by weight of flour powder, 2% by weight of rice straw, 1.5% by weight of water-soluble organic fertilizer, 1% by weight of ceramic powder % and a vegetation soil composition for slope greening comprising 2% by weight of charcoal powder is proposed. However, this vegetative soil composition has good moisture retention, breathability, adhesion, and root stability, and promotes seed germination and growth of germinated plants with various organic substances, but does not smoothly discharge water-soluble organic fertilizers adsorbed to vermiculite. Rather, there is a problem in that it is difficult to sustain seed germination or plant growth.

Therefore, when the conventional artificial soil as described above is constructed over a certain thickness on the incision site, the cohesive force between the constituents is weak over time, causing cracks and partial dropouts or sliding, and there is a high possibility that rapid greening may be limited. There were disadvantages such as the inability to stabilize the slope.

Therefore, the main purpose of the present invention is to enable fast and solid support and greening of the slope, and at the same time, considering the construction method, construction thickness, characteristics of the construction site, seasonal factors and expected weather, anyone can easily mix and construct the slope with the best combination. An object of the present invention is to provide a greening method using a soil mixture for greening and stabilizing slopes that efficiently promotes greening and stabilization and keeps it in the best condition.

Another object of the present invention is to provide a greening method using a soil mixture for slope greening and stabilization, which can promote the germination of seeds by applying good-quality soil to the slope and continuously help the growth of seeds and plants. is to provide

Another object of the present invention is to provide a greening method using a soil mixture for slope greening and stabilization, which can promote slope greening and stabilization by continuously suppressing partial fall-off or sliding due to weakening of cohesion on the slope.

In order to achieve the above object, the greening method using a soil mixture for greening and stabilizing slopes of the present invention is 47% by weight of loess, 18% by weight of palm fiber, 14% by weight of expanded rice straw, 10% by weight of expanded rice husk, decomposition of gelatin and chitin 6% by weight of microorganisms, 3.5% by weight of wheat flour, 1.5% by weight of seashell fine powder, but adding flour to the palm fiber, expanded rice straw, and expanded rice husk, and first mixing the surface of palm fiber, expanded rice straw, and expanded rice husk a first mixture in which flour is applied to the flour, then ocher, seashell powder, gelatin and chitin-decomposing microorganisms are secondarily added and mixed; Comprising of 48% by weight of humus, 17% by weight of vermiculite, 12% by weight of diatomaceous earth, 5% by weight of natural minerals, 12% by weight of water-soluble organic fertilizer, 4% by weight of water-soluble gelatin, and 2% by weight of bacillus, the vermiculite is used as a water-soluble organic fertilizer After forced precipitation in the water for 30~40 minutes, it is poured into water-soluble gelatin, coated with a gelatin film on the vermiculite surface, and dried to block the outflow of the adsorbed water-soluble organic fertilizer, then humus, diatomaceous earth, natural minerals, residual water-soluble organic fertilizer, and residual water-soluble organic fertilizer a second mixture in which water-soluble gelatin and bacillus were added and mixed while vermiculite forming a gelatin film was added and mixed; and plain loam; 15 to 25% by weight of the first mixture, 15 to 25% by weight of the second mixture, and 50 to 70% by weight of general loam to form a main mixture and construct on the slope; a greening groove forming step of digging horizontal grooves and vertical grooves continuously or at equal intervals on the slopes or forming circular grooves in a predetermined arrangement; When the greening groove forming step is completed, a greening groove filling step of adding and mixing the seeds of a plant into the second mixture, and then filling the second mixture with the seeds into the greening groove; When the greening groove filling step is completed, the greening groove stacking step of covering the first mixture on top of the second mixture; When the greening groove stacking step is completed, plant seeds are added to the main mixture, mixed, and then applied to the entire slope to constitute including the slope construction completion step; The basic feature of its technical configuration is that it can be efficiently controlled according to the conditions such as the characteristics of the construction site and seasonal factors so that the slopes can be greened in the best condition.

Therefore, the greening method using the soil mixture for slope greening and stabilization of the present invention is to form a main mixture with 15 to 25% by weight of the first mixture, 15 to 25% by weight of the second mixture, and 50 to 70% by weight of general loam. be constructed on all sides; Digging horizontal grooves and vertical grooves continuously or at equal intervals on the slope or digging circular grooves in a certain arrangement to fill the grooves in the second mixture, cover the first mixture on top of the second mixture, and then apply the main mixture to the entire slope. As the slope construction is completed, it not only stabilizes the slope quickly and firmly and allows recording, but also considers the construction method, construction thickness, characteristics of the construction site, seasonal factors, and expected weather, so anyone can easily mix and build the best combination for construction. Efficiently promote greening and stabilization of the slopes to maintain the best condition stably, but by continuously providing sufficient high-quality elements over a long period of time so that plants can be firmly established, it is effective by promoting the germination and growth of seeds sufficiently. there is

The greening method using the soil mixture for greening and stabilizing slopes of the present invention includes a first mixture that mainly improves the bearing capacity of a slope, a second mixture that mainly induces seed growth and strong settlement of bulbs, and suppresses drying of the slope It consists of a soil humectant, and general loam; 15 to 25% by weight of the first mixture, 15 to 25% by weight of the second mixture, and 50 to 70% by weight of common loam to form a main mixture.

Here, the first mixture mainly improves the bearing capacity of the slope, but includes loess, palm fiber, expanded rice straw, expanded rice husk, gelatin and chitin-decomposing microorganisms, wheat flour, and seashell powder.

In addition, the second mixture mainly induces seed growth and firm settlement of bulbs, but includes humus, vermiculite, diatomaceous earth, natural minerals, water-soluble organic fertilizer, water-soluble gelatin, and bacillus.

The first mixture for improving the bearing capacity of the slope is 47% by weight of loess, 18% by weight of palm fiber, 14% by weight of expanded rice straw, 10% by weight of expanded rice husk, 6% by weight of gelatin and chitin-decomposing microorganisms, 3.5% by weight of wheat flour, fine seashells Ideally, it is formed by including 1.5% by weight.

The loess is mainly composed of silt-sized particles with a diameter of 0.005 mm or less, which suppresses moisture evaporation, improves soil viscosity, and prevents soil acidification. It can be used after drying sufficiently so that the particles do not agglomerate with each other. It is preferable to allow

The palm fibers are pulverized to have a directionality in the longitudinal direction so as to form fibers having a certain length from the skins to extract fibers from the pulverized skins. After soaking the pulverized skins in water for a certain period of time, the fibers are peeled off one by one. use. These initial wet palm fibers are sufficiently dried naturally so that the moisture content is maintained at 22% or less, thereby keeping the surface of the palm fibers dry and inducing them to be thinly applied when flour is applied to prevent tangling. It is preferable to Here, if the palm fiber has a moisture content of 22% or less, there is almost no moisture on the surface, and the dry state is maintained. These dried palm fibers are cut to form 80~90% of 4~5cm in length, and 10~20% of them are shaped to be 7~8cm in length, so that the sliding shape of the slope is improved by effectively interacting with each other on the slope in the future to enhance the bearing capacity. Ideally, it should be able to suppress effectively.

The expanded rice straw is expanded by heat treatment, etc. and naturally dried. Such expanded rice straw not only increases the mutual support, cohesion and cohesion of the soil, but can also maintain it continuously for a long period of time. It is rich in organic matter, phosphoric acid, silicic acid or nitrogen, etc. Since it is induced with organic compounds, it increases the soil's bearing capacity, cohesion and cohesion, and at the same time promotes the growth and development of seeds and plants. These straws are cut by removing the husks, but 75-80% of them are formed in a length of 2 to 3.5cm, and 20-25% are formed in a length of 5-6cm, and it is ideal to supply them with the surface of the rice straw dry enough by natural drying.

The expanded rice hull is preferably used after heat treatment to expand the raw rice husk and remove moisture. Here, the raw chaff has coarse bristles on the surface, is minced with lignin, and is deposited with silicic acid in the epidermal cells. It is preferable to use what was expanded using a softening device. Since this expanded rice husk has sufficient soft tissue and water absorption, fermentation is fast and gas generation is remarkably reduced. In particular, the expanded rice hull in the present invention is preferably ground to a size of 0.8 mm or less to make it rough, and then slowly roast and dry it and carbonize 5 to 8% to facilitate mutual adhesion with the aggregated materials.

The gelatin and chitin decomposing microorganisms not only enhance disease resistance by killing nematodes and pathogenic fungi by the gelatin and chitin decomposing microorganisms in the soil, but also promote the growth of crops. . In other words, the larvae and egg sacs of nematodes, which are harmful to crops, mainly consist of gelatin, and the egg shells and pathogenic fungi of pests contain a large amount of a substance called chitin. When chitin-degrading microorganisms are used, nematodes and pathogenic fungi, which have been found to be the cause of various diseases and pests, can be blocked at the source, so that the germination and growth of early seeds can be effectively dealt with.

The flour improves cohesive force on the slope together with loess to suppress the phenomenon of cracks, partial dropouts, or sliding, which are likely to occur due to weakening of the cohesive force on the slope.

The shell powder, calcium, calcium carbonate, etc., including various amino acids, gradually escapes and induces alkalinity to prevent soil acidification and at the same time promote plant cell regeneration, thereby stably inducing early germination of plants and efficiently greening. make it possible It is preferable to prevent deterioration of binding force by grinding the shells from which impurities are removed by washing, and then pulverizing them to a particle size of 0.4 μm or less, and at the same time providing 1.5% by weight or less.

The first mixture of the present invention is applied by first adding flour to palm fiber, expanded rice straw, and expanded rice husk in a stirrer, etc., and then sufficiently mixing it by stirring, etc., so that the surface of palm fiber, expanded rice straw, and expanded rice husk maintains a dry state. Apply a relatively thin layer of flour.

Next, loess, clam shell powder, gelatin and chitin-decomposing microorganisms are secondarily added and sufficiently stirred to complete the first mixture.

The second mixture for inducing the growth of the seeds and the firm settlement of the bulbs is 48% by weight of humus, 17% by weight of vermiculite, 12% by weight of diatomaceous earth, 5% by weight of natural minerals, 12% by weight of water-soluble organic fertilizer, 4% by weight of water-soluble gelatin, Ideally, the formulation contains 2% by weight of Bacillus.

The humus soil is made by rotting fallen leaves, deposited in a mountainous area, or artificially deposited, and may be used in combination with other soil or mixed soil. This humus soil has good drainage and ventilation, swells the soil, and induces physical properties to be maintained for a long period of time. Because it is porous, it has good drainage, has strong moisture and nutrient retention, increases the earth temperature, and is rich in various nutrients. Moreover, since such humus contains a large amount of organic matter, nitrogen, phosphoric acid, and potassium to rot or ferment by mixing axial or fermented soil, it provides humus, which provides sufficient nutrients for seed germination, germination, or growth promotion of planted plants. It is preferable to supply it properly.

The vermiculite is a porous material and its size is limited to 4 mm or less in diameter. After precipitating the well-dried vermiculite in water-soluble organic fertilizer, make it sufficiently adsorbed, and then apply water-soluble gelatin.

The diatomaceous earth is soil or rock in which the remains of single-celled algae called diatoms are deposited on the seabed or porcupine, and components in the body are decomposed to form a stratum formed by silicic acid-based crustaceans. And it can be applied to grass or monocotyledonous flowers due to its absorbency. In particular, silicic acid contained in diatomaceous earth is dissociated from the primary minerals of the soil and supplied to the plant roots, and the soil surface area is increased to physically and chemically absorb water, phosphoric acid, potassium, nitrogen, aluminum, heavy metals, etc. Silicic acid prevents the amount of a specific element from becoming too high and performs a cation buffering function that dissociates and supplies when it becomes low. At the same time, the silicic acid accumulated in the plant physically protects the tissue and prevents moisture from being discharged through the epidermal tissue and cell membrane. It is involved in the stability and physiological and biochemical reactions of the drug and can sufficiently increase resistance to unfavorable environments.

The Bacillus is a soil microorganism that can control plant growth, seed germination, stem elongation, leaf growth, flowering promotion, and pulp maturation, and has excellent activity for promoting plant growth, in particular, promoting root growth It has very excellent activity, so it is effective for early germination, has excellent vegetation restoration ability, and at the same time increases plant productivity, it can efficiently remove bad odors (odors) remaining in the soil by Bacillus.

The natural mineral is a material for regulating the physical, chemical, and root growth of the soil. Since it is a rhizosphere microorganism of crops, it not only regulates the absorption of moisture and nutrients, promotes root elongation, and inhibits the generation of harmful microorganisms, but also especially the rhizosphere microorganism is insoluble phosphoric acid It promotes plant growth through solubilization and nitrogen fixation, and suppresses the growth of pathogens or plant infection by producing HCN, siderophore, and antibiotics. Moreover, by promoting the growth of crops and strengthening the rhizosphere microorganisms with these natural minerals, various side effects caused by excessive use of chemical fertilizers, etc., as well as various side effects due to the excessive use of chemical fertilizers, are reduced, and the plant growth is promoted by strengthening the rhizosphere, so that the slope can be quickly stabilized by greening quickly. let it be

The water-soluble organic fertilizer contains nitrogen, water-soluble phosphoric acid, water-soluble potassium and growth promoting hormone. Here, growth-promoting hormones include plant growth hormones such as Cytokinins, Auxins, Gibberellins, and Betaines, and at the same time, elements such as amino acids, carbohydrates, vitamins, arginic acid, and sugars are evenly distributed. preferably included. Therefore, it not only improves the germination ability of seeds, but also improves the development of healthy roots and stem systems, and the resistance to environmental conditions.

The water-soluble gelatin contains 18 kinds of amino acids as the main component of the protein, and these amino acids contained in the water-soluble gelatin activate metabolism in plant growth, enhance photosynthetic ability, increase growth, enhance muscle hypertrophy, promote root development, Increases resistance to various environmental disturbances such as Here, it is preferable to use water-soluble gelatin by heating and decomposing collagen, an insoluble protein contained in animal bones, skins, tendons, etc., with water to form water-soluble gelatin.

In the second mixture of the present invention, the dried vermiculite is precipitated in the water-soluble organic fertilizer, and at this time, the forced sedimentation state is maintained using a pressing means, etc., so that the water-soluble organic fertilizer can be sufficiently adsorbed to the vermiculite for 30 to 40 minutes. to keep the status quo.

Here, the vermiculite after the precipitation operation is immediately put into water-soluble gelatin, coated on the surface of the vermiculite, and dried sufficiently to block the outflow of the adsorbed water-soluble organic fertilizer to form a gelatin film on the surface of the vermiculite.

Next, humus, diatomaceous earth, natural minerals, residual water-soluble organic fertilizer, residual water-soluble gelatin, and bacillus are added to a stirrer, etc., and the vermiculite which forms a gelatinous film while stirring is added and sufficiently stirred to complete the second mixture.

The main mixture is mainly composed of 15 to 25% by weight of the first mixture for improving the bearing capacity of the slope, 15 to 25% by weight of the second mixture mainly for inducing seed growth and firm settlement of bulbs, and 50 to 70% by weight of general loam complete including. Furthermore, in the main mixture, an appropriate amount of seeds is mixed in consideration of the characteristics of the selected plant and applied to the design thickness on the slope. In case of severe dry season or drought, add enough moisture by adding 5~15% by weight of a soil humectant that suppresses drying. Therefore, it is desirable to promote the germination and growth of plants. Here, the soil humectant uses a mixture of substances such as water absorption polymers, nutrient elements, growth promoters, and electrolytes, and at the same time stores a large amount of moisture to smoothly supply moisture to the roots of plants when plants germinate and grow. make it possible In particular, the main mixture of the present invention mainly uses the first mixture for improving the bearing capacity of the slope, and the second mixture for inducing the growth of seeds and the strong settlement of the bulbs. It is analyzed based on weather forecasts and mixed in the best ratio, and at the same time, it is mixed with one-sided loam and constructed on the design slope, so that the slope can be stably stabilized and rapid greening can be realized. Furthermore, when the main mixture is mixed with the first mixture, the second mixture, and the general loam, the gelatin and chitin-decomposing microorganisms of the first mixture kill nematodes and pathogenic fungi in the general loam, and at the same time slowly gnaw the gelatin coated on the vermiculite surface. The water-soluble organic fertilizer adsorbed to vermiculite flows out slowly and is supplied for a long period of time, so it can induce and promote rapid and stable germination and growth of plants.

An embodiment of the greening method using the soil mixture for greening and stabilizing the slope of the present invention will be described as follows.

15 to 25% by weight of the first mixture, 15 to 25% by weight of the second mixture, and 50 to 70% by weight of general loam to form a main mixture and apply it on the slope; a greening groove forming step of digging horizontal grooves and vertical grooves continuously or at equal intervals on the slopes or forming circular grooves in a predetermined arrangement; When the greening groove forming step is completed, a greening groove filling step of adding and mixing the seeds of a plant into the second mixture, and then filling the greening groove with the second mixture mixed with the seeds; When the greening groove filling step is completed, the greening groove stacking step of covering the first mixture on top of the second mixture; When the greening groove lamination step is completed, plant seeds are put into the main mixture, mixed, and then applied to the entire slope, including the slope construction completion step.

The greening groove forming step is formed by digging and forming a plurality of greening grooves in the lateral and longitudinal directions in the slope, but the greening grooves may be formed in various shapes and standards with reference to the characteristics and inclination of the slope. However, the depth of the green groove is 1.5~3cm suitable to cover the seeds and to concentrate the nutrients sufficiently. Furthermore, in the case of a slope of a slope or a rock, it is possible to reinforce the lower support force of the greening groove by installing a support piece or the like at the lower side of the greening groove.

In the greening groove filling step, the first mixture is filled in each of the various greening grooves formed on the slope, and the first mixture is pressed and filled sufficiently, so that the first mixture projects outward of the slope by 0.6 to 1.2 cm. In this case, it is natural to mix an appropriate amount of seeds in the first mixture according to the type of plant for slope greening.

In the greening groove lamination step, it is preferable to press the second mixture on the upper surface of the first mixture press-fitted into the greening groove and apply it in a thickness of 0.8 to 1.2 cm while supplying sufficient moisture.

In the step of completing the slope construction, the first mixture, the second mixture, and the general loam are mixed with the main mixture to the design thickness of the main mixture and applied to the entire slope, but in the case of severe drought or dry season, soil moisturizer 5 to 15 It is preferable to add enough moisture to plant seeds and the like by adding it in weight %.

On the other hand, the present invention can selectively supply moisture as needed in each step.

In addition, the present invention efficiently constructs the first mixture and the second mixture according to the characteristics even if the thickness to be installed on the slope is thin, so that the best slope greening is achieved by stabilizing the slope or smoothly supplying nutrients to the soil, seeds and plants. can be obtained

In particular, since the main mixture is applied in a state in which the second mixture is laminated on the first mixture, greening is intensively induced in the greening groove, so that the slope can be quickly and firmly stabilized.

Therefore, the greening method using the soil mixture for slope greening and stabilization of the present invention has excellent moisture retention rate, air permeability, adhesion and root adhesion, so that the germination of seeds and growth of germinated plants is promoted as well as adhesiveness. Not only can it prevent cracks, partial dropout, and sliding, but the water-soluble organic fertilizer absorbed into the pores of the vermiculite is a water-soluble organic fertilizer that has been absorbed by the gelatin and chitin-decomposing microorganisms by gnawing the gelatin membrane coated on the surface of the vermiculite. As it slowly flows down, it supplies nutrients to the soil, so that it can continuously promote germination and growth of plants to obtain sufficient greening to the desired stage.

In the present invention, the above embodiments are examples, and the present invention is not limited thereto. Anything that has substantially the same configuration as the technical idea described in the claims of the present invention and achieves the same operation and effect is included in the technical scope of the present invention.
