Generally, incisions of rivers, coasts, and roads are steep areas, no topsoil or thin layers, or even areas with poor topsoil, which are difficult to grow plants. In this environment, various vegetation greening methods are used to create artificially good growth environment.

Most vegetation greening methods use vegetation-based material spraying method that coats large amount of vegetation soil thickly on target slope and sprays greening composition such as seed, fertilizer, adhesive, moisturizer and coating curing agent to the target area. However, because the existing greening method is a method of attaching only the seed to the artificial soil and attaching it, there is a disadvantage that the vegetation of the plant falls over time unless continuous management is followed.

The greening method is applied in various ways according to the slope, soil, rock quality, surrounding landscape, etc., and it is classified into dry type and wet type according to the installation method. For the high germination rate and fast sticking of seeds, the development of materials and composition of moisturizers and mixtures such as loess, activated carbon, sawdust, foliar soil, sewage sludge are proceeding rapidly.

      SUMMARY OF THE INVENTION An object of the present invention is to provide a soil composition for greening and a greening method using the same, which induces plant growth rate and long-term transition by satisfying the requirements for plant germination and initial growth.

It is another object of the present invention to provide a greening soil composition and a greening method using the same, which can improve the germination and root growth ability of plants in the fill and cut areas.

According to the present invention for solving the above problems, the ecological restoration greening method using the soil composition for greening containing the soil microbial colony culture cultured using the topsoil of the slope greening construction site or the topsoil collected from the surrounding natural environment Is provided.

Example

Soil Microbial Community Culture Preparation

Microorganisms are microscopic organisms that are usually less than 0.1mm invisible to the naked eye and are classified into bacteria, filamentous fungi and actinomycetes. Hundreds of thousands of microorganisms in the soil affect plant growth. Of these, about 900 are classified as effective microorganisms and about 100 as harmful microorganisms. They have a mutual influence on both good and bad directions and are involved in the circulation of carbon, nitrogen, and various minerals as they multiply and survive, and affect the roots of higher plants.

Recently, microbial agents using specific useful microorganisms, such as Bacillus , Trichoderma , and VA fungi, have been developed and used to promote crop growth and prevent diseases. However, if the microorganisms added with only these specific microorganisms are used in a natural state in which hundreds of thousands of microorganisms form a stable colony by interaction, the balance between the microorganisms may be detrimental and adversely affect the entire ecosystem, or the added microorganisms may settle in the soil. The result may be death rather than failure.

Therefore, in the present invention, the soil microbial colonies, which have grown in a stable colony structure of the soil microbial colonies growing in the soil collected in the natural environment around the construction site, are mixed with the greening soil composition, and the greening soil composition is also stable soil microorganisms. By allowing the colonies to grow smoothly, they not only maintain and improve the structure and fertility of the soil, but also create favorable conditions for the early growth of plants and restore them to match the natural vegetation around them. In order to induce desirable ecological restoration, we tried to invent a greening soil composition and an ecological restoration greening method using the same.

In order to demonstrate the effect of the present invention, soil samples were collected from representative forest soils (oak communities), and the weight ratio of mixtures having different mixing ratios of A, B, C, D, E and 1: 1000 topsoil: mixture). Maintaining the environment at a humidity of 50% and a temperature of 40 ° C. to primary culture of the soil microorganisms for 5 days, and the primary culture was again mixed with a mixture of the respective mixing ratios of 1: 1000 (primary culture: The mixture was mixed at a weight ratio of 50% and maintained at an environment of 50% humidity and second culture for 5 days.

In order to form a soil microbial culture suitable for the growth of microorganisms, by-products of the culture according to carbon ratio (C / N) were examined to select suitable materials as shown in [Table 1].

<Table 1> Soil Microbial Culture Selection

Soil microbes use carbon compounds as metabolites to multiply cells and generate energy. But no organism can multiply and grow on carbon alone. Since microorganisms need nitrogen to synthesize nitrogen-synthesizing cell components such as amino acids, enzymes, and DNA, carbon and nitrogen are necessary as a source and energy source of microorganisms. As shown in Table 1, by-products close to the C / N ratio of the average forest A layer of 20 were selected as cultures, and a stable soil microbial colony culture was obtained by securing a food source with sufficient supply of carbon and nitrogen required by microorganisms. You can make it.

Soil microbial cultures thus selected were subjected to counting by type of microorganisms present in each of the constituent blends at intervals of 2 days after the secondary culture. [Table 2-3]

<Table 2> Mixture Composition for Soil Microbial Culture Test

Table 3: Coefficients by Type of Microorganisms in Each Composition

The total number of microorganisms in A composition using only boiled bran and brown sugar used as a general experimental group was 145 × 10 ⁴ after 6 days of cultivation, resulting in B composition (240 × 10 ⁵ ), C composition (183 × 10 ⁵ ), and D composition ( 175 × 10 ⁵ ) and lower than the E configuration (507 × 10 ⁶ ). In addition, the ratio of bacteria, actinomycetes, fungi, and tricotema among all microorganisms showed that the ratio of bacteria and actinomycetes was lower than that of uncultivated forest soils (natural microbial distribution). The proportion of derma was relatively high.

The total number of microorganisms in B composition using rice straw and corn hay was relatively higher than A composition (145 × 10 ⁴ ), but C composition (183 × 10 ⁵ ), D composition (175 × 10 ⁵ ), and E composition (507 × 10 ⁶ ) was relatively low. Compared to the forest soils, the proportions of B-types were reduced in bacteria, actinomycetes, and fungi, and the percentage of trichodems was increased. Although the microbial ratios of C and D are still low, they are closer to the distribution of forest soil microorganisms than A and B.

E composition, the most suitable composition ratio of the present invention, compared with other components, the total number of microorganisms increased, and appeared similar to the microbial distribution ratio of uncultivated forest soil.

From the above results, the mixing ratio using boiled bran and brown sugar showed similar coefficients to the total density of microorganisms in the natural state, but the results were not for the purpose of growth culture. It did not serve the purpose of maintaining the ratio of natural state. B, C and D showed higher than the total density of microorganisms in the natural state, but the ratio of one or two species was higher or lower in the ratio of microorganisms, which did not meet the purpose of maintaining the natural state. In the proportion of E composition containing rice straw, ripe bran, corn hay, and brown sugar in a suitable ratio, the total microbial density was relatively higher than that of other blended and uncultivated forest soils. Similar to forest soils. These results indicate that rice straw, boiled corn hay, and brown sugar are replaced by boiled bran, wheat sugar (brown sugar) culture, which is generally used for microbial culture, and not only as a food source for microorganisms but also as a suitable ph, moisture, and oxygen supply for microbial growth. It can be seen that the proliferation while maintaining the distribution ratio of the microbial community in the natural state.
