Description

Method of slope recording to create a multilayer vegetation base {Methods of slope afforestation developing multilayer vegetation media}

The present invention provides a method for hillside forestry that matches with the flow of natural transition and maintains biodiversity for ecological restoration such as soil slope or rock slope generated by various construction works.

Slope greening is a technique that covers the surface layer by vegetation and contributes to the prevention of erosion. With the recent development of greening technology, it is possible not only to stabilize the slope but also to form a plant community that is permanently harmonized with the environment.

In the existing greening method, the construction method of dry single or wet single has been widely used depending on the quality of the soil or the material. For example, pneumatically-grown growth bases using a dry construction method are disadvantageous for plant root growth due to the high soil hardness of the foundation, and because the load of the material itself is high, the material is removed to solve the problem of dropping and collapse. It is becoming lighter. And in order to increase the early coating effect, the organic content in the vegetation base layer is made high, but the early coating effect is excellent, but when the nutrients are initially concentrated and depleted at once, there is a problem that the plants simultaneously decay.

In contrast, the wet construction method is a thin composition for the soil, some weathered rock, and the like. This is to promote and maintain growth until the plants germinate and roots are established on the ground, and it is difficult to maintain the growth until the plants settle on the ground in poor growth conditions such as hard rock and steep slopes. There is this. Therefore, continuous control of nutrient supply at each stage in the growth base and subsidiary layers remains an important task.

At the same time, the combination of seeds serves as an important factor for ecological restoration. Conventionally, all the seeds were included in the vegetation base and constructed at one time, but in this case, there was a lot of seed loss, especially when woody species were introduced for the foresting, it was difficult to control the quality due to the competition between plants. Seeds have different germination depths depending on the characteristics of the individual seeds. Therefore, the composition thickness and the optimum blending ratio are very important for the blending of seeds for the purpose of planting, but the application technology differentiated for each construction method or ecological restoration goal is still very important. It was not developed.

On the other hand, the vast amount of wood waste generated in various construction works is classified as construction waste, and it is one of the wastes that have been strongly demanded for recycling due to expensive treatment costs and environmental problems such as being taken out and incinerated. Efforts to reuse wood waste have already been developed and utilized in Japan, which is a developed country in Japan, which replaces conventional vegetation-based materials. Although some technologies have been developed in Korea, effective technologies that can be easily applied to the site have not been developed and distributed. Therefore, a large amount of waste wood is being treated as waste without efficient recycling of wood waste.

In order to solve the above problems and problems, the present invention provides a method for restoring the local ecological environment before construction, matching with the surrounding landscape, maintaining biodiversity, and adapting to the flow of natural transition. It is to.

Therefore, the present invention is to provide the optimum seed germination conditions by attaching the growth base layer on the formation of the vegetation base, by mounting a growth auxiliary layer thereon to form a multi-layer vegetation base, wet type according to the soil conditions of the field It provides a recording method characterized in that the mounting by mounting alone or in combination with a dry and wet method. In addition, the slope greening method of the present invention is characterized by providing a greening method for creating a lightweight vegetation base by recycling wood waste generated in the construction site.

In the present specification, the vegetation base material is used to include both the growth auxiliary material and the growth base material, and the vegetation base or vegetation base layer is used to include both the growth auxiliary layer and the growth base layer.

According to the greening method according to the present invention by combining the wet + wet mounting method, or dry + wet mounting method according to the soil of the site, it is advantageous to plant growth, and create a stable vegetation base. Specifically, the wet mounting method performs work with a mounting machine in which water, material input, mixing, and spraying are integrated, and a vehicle that can be installed and moved while being installed and suited to the site conditions. The dry mounting method is a combination of equipment such as aliba, air compressor, crane, conveyor, etc. The mixed material is put into the alibar by the conveyor and constructed by air compression method.

More specifically, the present invention is a growth base material composition and growth aid including cotton fiber, paper fiber, loess, fecal soil, organic compost and wood waste (wood waste raw chips and / or wood waste shredding compost) generated in construction sites, etc. It provides a greening method characterized in that by mounting the composition to form a growth base layer and a growth auxiliary layer to form a multi-layer vegetation base. The greening method according to the present invention is characterized in that it provides a vegetation base of a multi-layer structure comprising a growth base layer and a growth auxiliary layer formed from the growth base material and the growth auxiliary material, wherein the growth base layer is a plant settled roots As a space to grow, it plays a role of securing plant support, supplying nutrients and moisture, and the growth auxiliary layer promotes germination and growth, inhibits water evaporation until the plants settle roots on the ground or growth base layer. It performs functions such as rainfall erosion suppression. Mounting of the growth base material and the growth auxiliary material may be performed by combining a wet mounting method, or a wet mounting method and a dry mounting method according to the site soil.

Growth base material composition for growth base layer composition and vegetation base material composition for growth auxiliary layer composition is 5 to 30% by volume cotton fiber, 5 to 40% by volume paper fiber with specific gravity 0.8 or less, 5 to 30% by yellow soil, fecal soil 5 to 30% by volume of organic compost, 10 to 30% by volume of organic waste and wood waste 15 to 40% by volume, according to the content ratio of wood waste raw chips and wood waste shredding compost in the wood waste It is distinguished by a composition.

The growth base layer is characterized in that it comprises from 15 to 40% by volume, preferably 20 to 35% by volume of wood waste raw chips, based on the total composition volume, in order to perform a physical role as a support base of the plant roots. Therefore, the growth base material composition for the growth base layer composition is 5 to 30% by volume cotton fiber, 5 to 40% by volume paper fiber with a specific gravity of 0.8 or less, 5 to 30% by volume ocher, 5 to 30% by volume of fecal soil, organic compost 10 To 30% by volume, wood waste raw chips 15 to 40% by volume, preferably 20 to 35% by volume, and wood waste crushing compost 0 to 10% by volume, preferably 3 to 7% by volume.

Since the wood waste raw chips are composed of fibers having a length of about 3 to 5 cm in length, short fibers are mixed with the base material to increase tensile force, thereby obtaining a stable support base. In a preferred embodiment, the growth base layer comprises about 45% soil (ocher and fecal soil), fibres (cotton and paper fibers) and organic matter (organic compost and wood waste) at about 55%. Can serve as soil.

On the other hand, in the growth auxiliary layer, the use rate of wood waste raw chips is reduced to 0 to 12% by volume, preferably 5 to 10% by volume, and the shredding compost made from wood waste is 15 to 40% by volume. Is characterized in that the compounding in 18 to 37% by volume. The growth auxiliary layer is a place where seeds germinate to obtain initial nutrients, so it is preferable to include a large amount in the form of crushing compost. In addition, blending raw wood waste chips to 5% by volume or more and less than 15% by volume, preferably 7 to 13% by volume, is intended to play a role of preventing the erosion due to rainfall at the surface layer only when the short fibers are properly reinforced. That is, raw chips and compost are combined to form a multi-layered layer, and in a preferred embodiment, the growth auxiliary layer is composed of 30% of soils, 70% of fibers and organics, and serves as an organic layer of soil. It may be.

If the construction thickness (growth layer thickness + growth auxiliary layer thickness) is about 1 to 4 cm, about 2 cm, 0.5 to 2 cm for the growth base layer, preferably about 1 cm, 0.5 to 2 cm, Preferably, the composition may be about 1 cm. In particular, when the construction thickness is 0.5 to 2.5 cm, for example, about 2 cm, most of them are applied to the level of the ripping arm, so the growth base of the plant is insufficient. The remaining thickness can be formed as a growth auxiliary layer. In this case, the construction method may use a wet method for both the growth base layer and the growth auxiliary layer.

If the construction thickness is about 4 to 10 cm, preferably 6 to 8 cm (about 7 cm), the growth base layer is 3.5 to 8 cm, preferably 5 to 7 cm (about 6 cm), the growth auxiliary layer 0.5 To 2 cm, preferably about 1 cm. Construction site with a construction thickness of about 7cm is mainly a blast rock slope, so the slope is steep and there is no plant growth base at all. Therefore, it is better to make the thickness of the growth base layer and the growth auxiliary layer as described above, wherein the construction method is a dry method when forming the lower growth base layer, and a wet method when forming the upper growth auxiliary layer. good. The reason why the lower growth base layer is formed dry is because the construction method of the dry method is excellent enough that the desired construction thickness can be formed by one construction when thickly formed on the steep slope, and the upper growth auxiliary layer is constructed by the wet method. The reason is to avoid problems such as crack generation, dry damage, and soil hardening by consolidation which are problems of dryness.

Looking at the recording method according to the present invention for each soil as follows.

In the ripping arm section, the vegetation base material is intensively attached to the uneven surface and the joint of the inclined surface, and it is recorded on the ground. After installing the natural cotton net (for example, natural cotton net), the growth base layer and the growth auxiliary layer can be sprayed two or three times, and can be performed by using a dedicated equipment in which material input, mixing, and spraying are integrated. First, the growth base layer may be formed to a thickness of about 0.5 to 2 cm, preferably about 1 cm, and the growth auxiliary layer may be formed on the thickness of about 0.5 to 2 cm, preferably about 1 cm, and the average thickness is about 1 To 4 cm, preferably about 2 cm.

The thick layer mounting method with more than 4cm of thickness is applied to rock slopes and the dry base material composition is sprayed onto the site by spraying the growth base material composition to form the growth base layer from the high pressure hose. After the attachment network is installed for close contact, the growth base layer may be 3.5 to 8 cm, preferably 5 to 7 cm (about 6 cm). The vegetation base material composition may be mounted by a wet method in order to form a growth auxiliary layer on the growth base layer, and the construction thickness is 0.5 to 2 cm, preferably about 1 cm, and the overall construction thickness is 4 to 10. cm, preferably 7 cm.

In this regard, a schematic diagram showing functional division according to soil level and a conceptual diagram of a growth base layer and a growth auxiliary layer composition method according to an embodiment of the present invention are shown in FIGS. 1 and 2, respectively.

In sloped greening, seeds are mixed with materials to form a thick layer. In general, seeds located 2 ~ 3 cm deep from the surface can germinate, but seeds located below them are difficult to germinate. Appropriate cover thickness for each seed for restoring damaged paper is shown in Table 1 below.

Therefore, in the present invention, the seed is placed only 2 cm deep from the surface for the grove of damaged slopes, thereby reducing the amount of use of the seed, thereby increasing the economic efficiency and improving the work efficiency, and at the same time, the optimum seed composition according to the restoration target for each herb and wood seed, and each seed. To create an optimal cover thickness.

As shown in Table 1, the preferred covering thickness may be about 0.2 to 3 cm, but is not limited thereto, and may be appropriately adjusted according to the applied plant.

The vegetation-based composition and used in the greening method of the present invention may be cotton fiber, paper fiber, loess, fecal soil, organic compost and wood waste as described above. More specifically, the plant vegetation base composition is 5 to 30% by volume of cotton fibers, 5 to 40% by volume of paper fibers with a specific gravity of 0.8 or less, 5 to 30% by volume of loess, and 5 to 30 of fecal soil Volume%, 10-30 volume% of organic compost, and 10-40 volume% of wood waste. In addition, the plant vegetation base material composition may further comprise 0.5 to 3% by volume of the chemical fertilizer, 0.1 to 3% by volume of the adhesive.

In order to apply a thickness of 2-3 cm on the rock reflecting surface (see Fig. 3), the vegetation base material composition and the growth base material composition is 8 to 25% by volume of cotton fiber, 10 to 10 of the paper fiber with a specific gravity of 0.8 or less 40% by volume, 10 to 30% by volume of loess, 10 to 30% by volume of fecal soil, 15 to 30% by volume of organic compost, 15 to 35% by volume of wood waste, and 0.5 to 3 volumes of chemical fertilizer %, And 0.1 to 2% by volume of the adhesive, the bio supplement composition may be composed of wood waste in the wood waste content of 0 to 15% by volume, wood waste shredding compost content of 15 to 40% by volume. have. At this time, since the biological growth base of the base is not good, the growth base layer and the growth auxiliary layer may be formed in a thickness ratio of about 1: 0.8 to 1.2, preferably about 1: 1.

As another example, in order to apply a thickness of 7-9 cm on the rock reflecting surface (see Fig. 3), the vegetation base material composition is 8 to 30% by volume of cotton fiber, 15 to 15% of paper fiber with a specific gravity of 0.8 or less 40% by volume, 10 to 25% by volume of loess, 10 to 30% by volume of fecal soil, 15 to 30% by volume of organic compost, 15 to 40% by weight of wood waste and 0.5 to 3% by volume of chemical fertilizer And 0.1 to 3% by volume of the adhesive.

Hereinafter, the plant vegetation base composition according to the embodiment will be described for each component.

First, the plant vegetation-based composition comprises cotton fiber and paper fiber.

Among them, paper fibers are generated in the paper manufacturing process, and the main component is cellulose, specific gravity is 0.8 or less, and the unit weight is 0.76 g / cm 2 or less, and is composed of light and fine fibers. This paper fiber has a water content of about 65%, a solid content of about 35%, a solid content of pulp of about 64%, an organic content of about 36% or more, and excellent water absorption and water retention.

These paper fibers consist of polymeric fibers and increase in viscosity when mixed with water. Thus, as such paper fibers are included, it is possible to reduce the use of an adhesive for installing the plant vegetation base composition on cut slopes or fill slopes, and other components of the plant vegetation base composition may be incorporated into the fiber of the paper fiber. It can hold | maintain in between and can reduce the loss by the rain etc. of these components. In addition, the paper fibers can maintain a certain hardness during drying can also suppress soil erosion due to rainfall.

Such paper fibers are preferably mixed with organic compost and included in the plant vegetation composition for a period of time, e.g., at least three months.

On the other hand, the cotton fiber is made of fiber as in the above-described paper fiber, but is composed of long fibers as compared to the paper fiber. These cotton fibers have a structure in which fine fibers are irregularly connected, and thus have a large specific surface area and excellent adsorption and water absorption capabilities. Thus, as the plant vegetation-based composition includes such cotton fiber, it can exhibit excellent water retention and bobbin power. In addition, since the cotton fiber is composed of light and elastic vegetable fibers, it does not harden like paper fibers when dried. Therefore, the cotton fiber can lower the hardness of the plant vegetation base material composition, and because the specific gravity is light, the plant vegetation base material composition can be prevented from flowing down due to its own weight on the inclined fill slope or cut slope.

The paper fibers and cotton fibers can be used without limitation any material conventionally used in plant vegetation base composition. For example, the paper fibers and cotton fibers disclosed in Patent Registration No. 612767 can be used.

In addition, the paper fiber may be included in the content of 5 to 40% by volume in the plant vegetation base composition, the cotton fiber may be included in an amount of 5 to 30% by volume. If such paper fibers are included in less than 5% by volume, the plant vegetation base composition may not have sufficient viscosity and hardness, and each component of the plant vegetation base composition mounted on the slope may be lost by rainfall. On the contrary, when cotton fiber is included in a small content of less than 5% by volume and paper fiber is included in a large content, the specific gravity is increased so that the plant vegetation-based composition can flow down by the weight on the slope. Therefore, by adjusting the content of the paper fibers and cotton fibers in the preferred range described above, it is possible to suppress the cracking or loss of the plant vegetation base composition and to maintain the hardness of the plant vegetation base composition appropriately.

On the other hand, the plant vegetation base composition also includes loess and fecal soil.

The loess refers to loess in the scientific sense, i.e. not abundant sediments, but to loess in the general sense, i.e. weathered residual soil. Since the loess is a soil containing a lot of clay and has a large surface area, the adsorption and ion exchange of water on the surface of the particles can be actively performed to improve the water holding capacity and the binding power together with the cation substitution capacity of the plant vegetation-based composition. have. In addition, the ocher has a high adhesiveness and cohesiveness can promote the granulation of the soil. In addition, the loess may play a role of reducing the thickness variation of the plant vegetation base material composition occurs when the water saturation and drying. In order for the volume to not vary depending on the presence of water, the plant vegetation base composition should include materials that are slow or substantially unresponsive to external environmental changes. However, in general, organic materials have properties that are easily changed by microorganisms and external environmental changes such as rainfall or temperature change, and thus there is a limit to maintaining a constant thickness of the plant vegetation-based composition. Thus, the ocher, which is a kind of inorganic material, may play an important role in reducing the thickness variation of the plant vegetation-based composition. As a result, the plant vegetation base material composition may reduce the thickness change range due to the ocher, and exhibit excellent cation substitution capacity, water holding capacity, and bobbing force.

In addition, the vegetation base material composition comprises a fecal soil, that is, earthworm fecal soil with the loess, such fecal soil may promote the granulation of the soil including the plant vegetation base composition with the ocher. Turn on. As the soil becomes granular, the air permeability and drainage can be improved, as well as the ability to improve the retention and water retention, and the soil can be a habitat for microorganisms.

Plant vegetation-based compositions include wood waste shredding compost with organic compost. By including such wood waste crushing compost, the vegetation-based composition contains not only an increased amount of organic matter but also shows improved water absorption and water holding capacity and cation substitution capacity. In addition, the vegetation base material composition can supply nutrients to the plant continuously for a long time compared with the conventional plant vegetation base material composition containing only organic compost.

In addition, the vegetation-based material composition includes the wood waste waste as it is in the form of raw chips of 2 to 5 cm, or at least a portion of the wood waste shredding composting composted, this wood waste shredding compost is a nitrogen fraction of the plant There is little risk of deficiency, and because it shows excellent adhesiveness compared to wood waste not composted, there is no fear that the amount of separate adhesive will be very large.

Thus, as the plant vegetation base composition of the present invention includes wood waste crushing compost, while allowing effective recycling of wood waste, plant growth aid is better in the medium to long term than previous vegetation base composition containing only organic compost. Effect.

However, the organic compost has the advantage of supplying the nutrients necessary for plant growth in the initial (1-2 years) of the construction of the vegetation-based material composition, but as it is rapidly decomposed, the plant vegetation in the medium to long term for ecological restoration After three to five years have passed since the construction of the base material composition, there is a disadvantage in that it does not continuously supply sufficient nutrients to the plant.

For this reason, the vegetation-based composition of the present invention includes wood waste shredding compost with the organic compost. Such wood waste crushing compost refers to the composting of at least a portion of the wood waste, such as plant herb, tree branch or root, for a certain period of time.

The wood waste crushing compost performs a function similar to the organic compost described above, but shows a difference in the characteristics of the compost. The organic compost is a manure of the livestock manure exerts the effect of enhancing the intelligence and induction of plant vegetation base material composition. In contrast, the wood waste shredding compost is at least a part of the wood waste from various construction sites, such as compost, compared to the general organic compost (compost fermented by mixing the sorghum and sawdust or rice straw, etc.) more than three times, Boeing power and CEC is effective to increase more than seven times. In addition, wood waste crushing compost is excellent in improving the physical properties of the soil, such as mechanical strength, breathability or drainage. In addition, since the wood waste shredding compost has a lower specific gravity than the organic compost, it helps to reduce the weight of the plant vegetation-based composition and is very effective in reducing the transport cost and construction cost including the weight. In addition, the wood waste shredding compost is slower than the organic compost, so in the medium to long term it is possible to continuously supply sufficient nutrients to the plant even after 3 to 5 years have passed since the construction of the plant vegetation base composition. have.

Therefore, as such wood waste shredding compost is included, the plant vegetation-based composition is increased in organic matter content, water absorption capacity, water retention capacity and cation substitution capacity, and can nourish the plant continuously for a long time, effectively plant growth Can assist.

On the other hand, the vegetation vegetation base composition is preferably among the various wood waste, including wood waste waste compost composted by maturing the trunk and root of the wood. As a result, it is possible to maximize the recycling of resources, to adjust the supply effect of nutrients to the plant in time, and to improve the physicochemical properties of the plant vegetation base composition.

When the wood waste is included in the plant vegetation base composition itself, the wood waste may temporarily absorb the nitrogen in the soil and inhibit plant growth. In addition, if wood waste is included in the form of wood chips, pores of various sizes may be formed to improve drainage and breathability of the soil in which the plant grows, but the soil including the plant vegetation base composition is easily dried and the plant is dried. It may be damaged. In addition, since the wood waste is low in stickiness, when the wood waste is included in the plant vegetation base composition as it is, it is necessary to mix a larger amount of a separate adhesive or the like to increase the stickiness. This can harden the plant growth by hardening the vegetation base on which the plant grows.

However, the plant vegetation-based composition according to the present invention does not include the wood waste as it is, and at least a part of the wood waste shredding compost composted form, as there is little concern about the inhibition of plant growth due to the strong absorption of nitrogen in the soil In addition, the soil is less likely to dry. In addition, the wood waste shredding compost has a relatively good adhesiveness, greatly reducing the need to increase the amount of adhesive used. In addition, the wood waste shredding compost has the advantage of being well mixed with cotton fiber, which is another component of the plant vegetation base composition. Therefore, the fiber of cotton fiber can attach wood waste crushing compost having various pores, and other components of the plant vegetation-based composition can be filled between the fibers of cotton fiber in the state of adsorbing ocher or various organic materials. Thus, the plant vegetation base material composition can be evenly laid on the surface to be constructed, and the plant vegetation base material composition once constructed can be suppressed from being lost by rainfall. Therefore, the plant vegetation-based composition including the wood waste shredding compost can maintain structural stability without additional measures such as increasing the content of the adhesive.

After all, as the plant vegetation base composition comprises a wood waste shredding composted at least a portion of the wood waste, various properties of the plant vegetation base composition can be maintained excellent and thereby effectively assist the growth of plants. have. Therefore, the wood waste may be effectively recycled by being included in the plant vegetation-based composition.

On the other hand, the wood waste shredding compost, the various wood wastes are crushed using a wood shredder, and mixed with a predetermined amount of condensed compost in order to help the microbial activity in the composting process, these mixtures are stacked in the fermenter at intervals of 5 to 10 days Overturning may include wood waste composted at high temperatures (65 ° C) for 2-3 months and at room temperature for 1-2 months.

In addition, the wood waste shredding compost may include non-composted wood waste comminuted to a certain size, for example, 25 mm or less, preferably 5 to 25 mm, with wood waste composted by decaying for a predetermined period of time. As such, when the wood waste includes both composted wood waste and non-composted wood waste, wood plant waste compost and the vegetation vegetation base composition comprising the same contains the appropriate pore, the plant vegetation base composition and the same Soil breathability or drainage can be adjusted accordingly.

In addition, the plant vegetation base composition may further comprise 0.5 to 3% by volume of the chemical fertilizer and 0.1 to 3% by volume of the adhesive, in addition to the above-described components. In some cases, the chemical fertilizer is additionally included to more effectively support plant growth, and the additional inclusion of the adhesive may further improve the adhesion of the plant vegetation base composition, and the plant vegetation base at the initial stage of construction. The loss of moisture from the ash composition can be suppressed.

As the adhesive, any conventional adhesive that has been used in the plant vegetation-based composition may be used without limitation. For example, as the adhesive, a vinyl-acrylic polymer resin present in the form of an aqueous emulsion may be used. Such an adhesive is excellent in adhesiveness and can form a thin film film when mixed with water and sprayed to suppress evaporation of water.

The plant vegetation base material composition described above may be installed on a cut slope or a fill slope in a manner to install the plant vegetation base material composition in parallel with the natural cotton net installation. This natural cotton net is to prepare for rainfall when the plant vegetation-based composition is not secured enough hardness after being mounted on the inclined surface. This natural cotton net is corroded by the plant vegetation base composition about 6 months after construction and can be used as a nutrient source for the plant. The plant vegetation base material composition may contribute to the stabilization of the inclined surface.

As described above, the ecological restoration method that combines the dry and wet mounting method to create a multi-layered vegetation base enables the combination of the optimal mounting method suitable for the soil conditions of the field, and the best growth for the germination conditions of the seed. It creates a soil layer that plays a role of foundation and growth support, and it is possible to effectively recycle wood waste from the construction site in the form of composting and shredding chips. Through this, it is possible to restore the vegetation in harmony with the biodiversity and the surrounding landscape of the artificially damaged slope, thereby achieving an excellent effect of achieving vegetation transition in the medium and long term.

Hereinafter, the present invention will be described in more detail with reference to specific examples. However, these embodiments are only intended to illustrate the invention, the scope of the invention is not limited by these embodiments.

Example 2: Construction floor  formation

The vegetation base material composition prepared in Example 1 was attached to form a construction layer. The construction method for each soil condition is shown in FIG.

Example 3: Construction  effect

According to the construction method of the construction thickness 7cm described in Figure 4, by mounting the growth base material composition prepared in Example 1 by the existing dry method to form a growth base layer of 6cm, and prepared in Example 1 thereon The prepared vegetation-based composition was mounted by a wet method to form a growth auxiliary layer 1 cm thick (composite layer). At this time, the seed mixture was mixed only to the growth auxiliary layer of the upper 1cm without mixing to the growth base layer. As a comparative example, the growth base material composition of Table 2 was mounted in a conventional dry manner to form a single layer of 7 cm (single layer) and the seed mixture was mixed with the whole layer.

Experiments were conducted on artificial slopes, and the number of germinated individuals was examined at weekly intervals for one month after construction.

The initial germination populations in the composite and monolayers prepared were shown in Table 3 below.

As can be seen from Table 3, in the conventional single layer composition method, the initial germination is late due to the drying of the surface layer and the decrease in moisture content, whereas in the composite layer composition method according to the present invention, germination starts from the seeds contained in the surface layer portion. The initial germination effect was excellent.
