Description

Greening method using green net

The present invention relates to a greening method using a green net. Specifically, the green net of the present invention is applied to a fill or cut surface where early vegetation cannot be introduced in a natural state, thereby promoting early germination of seeds and soil loss and three bones on a slope. The present invention relates to a greening method that can prevent moisture and maintain moisture and retaining power, resulting in an excellent improvement in coverage and Saturn.

In the past, grasses were generally planted for the protection of landscapes and slopes of damaged slopes, which are unavoidable due to civil engineering or landscaping, and slopes, which are inadequate soils. Since most of them are made of poor masato or hard soil, the adaptability of the field is greatly reduced during the work and growth, and the topsoil is lost due to ice water or rainwater during thawing or heavy rains, and the bones are damaged to damage the grass. The slope was collapsed and had a fundamental problem such as repeated earthwork and lawn repair.

In particular, grass planting is not only expensive because of all the processes depend on manpower work and limited supply and demand, but also is currently being applied to the area where aftercare is possible due to incongruity with surrounding vegetation.

Seed spraying, another greening method, is widely used for fill slopes because it can select various mixed seeds and has a large amount of unit construction. There are problems in construction, such as the need to carry out additional sowing at least two or three times due to the death or loss of seeds. Even if some seeds germinate or work, they do not show the normal vegetation effect due to the nutrient deficiency of the soil itself. .

Recently, a method of applying a coating of a coir net or jute mesh, which is a net structure made of natural fiber material, entirely dependent on imports from foreign countries, has been applied. Due to the slow decomposition of coir fibers composed of hair fibers, the bobby effect that plants need is only possible after five years, and it does not affect the physical properties of the soil. Poor construction, the construction effect is very minimal. In addition, since supply and demand depend on imports, supply and demand are opaque and construction costs are high, so there is an urgent need for alternative methods using domestic materials.

Accordingly, the present inventors have continued to study to solve the common problems of the greening method that has been applied so far, as a result, by applying the green net of the present invention to the fill or cut surface, it is possible to create a construction effect that was not expected so far It was found that the present invention was completed.

It is an object of the present invention to promote early germination of seeds on land or cut surfaces where early vegetation is not possible in nature and to prevent soil loss and three bones on slopes, and to continuously maintain moisturizing and stabilizing power to improve coverage and saturn. It is to provide a greening method using a green net that can be imported.

In order to achieve the above object, the present invention provides a mixture of 80 to 95% by weight of composite organic matter, 5 to 15% by weight of lime, 3 to 8% by weight of compound fertilizer, and 0.5 to 2% by weight of seeds. After installation, the present invention provides a greening method using a green net, which includes spraying seeds over the entire surface and installing a structure that combines straw and polyethylene mesh thereon.

Hereinafter, the present invention will be described in more detail.

In the present invention, "green net" refers to a plant for fill or cut surface greening, including a composite organic material, slaked lime, a compound fertilizer and a mixture of seeds, and a structure composed of rice straw and polyethylene mesh.

According to the present invention, the bone is preferably sold in consideration of the site characteristics within the range of bone width 2 to 5 cm, bone depth 2 to 3 cm, the distance between the bone and the bone 20 to 30 cm, the complex organic material as a soil improving agent in the bone Patent Publication No. 099734, "Gumbito composition"), calcined lime which is an acidic soil neutralizer, a compound fertilizer and a mixture of seeds can neutralize the acidified soil of the poor vegetation ground and supply various organic materials.

The mixture can be used in a bag made of jute mat (# 30) and Korean paper, which are natural fiber mats that can be easily decomposed in the soil, and the organic bag has a width of 2 to 5 cm. It can be freely adjusted and manufactured for convenient construction and management on site. 2 shows a schematic diagram of the organic bag.

In particular, cut soils are unlikely to be easily combined with the soil, unlike spread soils, and are more likely to be lost. Seeds that do not show a difference of at least about 5 days in early germination and at least about 35% in settling rate.

According to the present invention, the organic bag is placed in the bone and then sprayed in an appropriate amount so that the seeds, coating curing agent, erosion stabilizer and compound fertilizer per unit area (m ² ) can be sufficiently infiltrated into the vegetation ground using the spreader. Then, it is installed in close contact with the vegetation ground while moving from the top to the bottom of the structure that synthesized straw straw and polyethylene mesh easily. 1 shows a plan view of a structure in which rice straw and a polyethylene mesh are synthesized.

In general, the landfill area is created by artificial earthworking, so the capillary structure of the soil is not formed for a certain period of time, so that water deficiency necessary for plant growth often occurs. Due to the lack of moisture, proper soil maintenance is essential to maintain normal vegetation of fill or cut surface. Typically, the water that can be used for plant growth is called available water, which is present between the field moisture capacity and the permanent wilting point, the initial of the fill or cut surface. The primary cause of germination and vegetation insufficiency is the lack of soil moisture close to counterfeiting.

The rice straw used in the present invention suppresses evaporation of soil moisture and is excellent in water retention ability by rainwater, and is suitable for eliminating water deficiency of fill or cut surface, and in particular, water in suitable soil is capable of active microorganism decomposition. By shortening the period of conversion of various organic substances to inorganic components that can be directly used by plants, bringing the effect of substantial soil improvement. In addition, this rice straw is easy to ripen, supply organic matter to the plant, and adhere well to form a single grain within a week to promote the germination of seeds, 5 to 10 than the conventional seed spray (seedspray) method or coir net method The early germination is about 1 day, and the coverage after 45 days is about 75%, which is much more effective than the 35% and 45% coverage of the existing methods.

In addition, as can be seen in Table 1, even in the same natural fiber material, this straw straw and the existing coir fiber shows a significant chemical composition difference, the more lignin, the slower decomposition and the more hemicellulose or cellulose, the faster the decomposition from the viewpoint of In this case, rice straw rather than coir can be easily decomposed by active metabolism of soil microorganisms, and nitrogen content can also be used as an effective nutrient source for plants due to the large amount of rice straw.

In addition, the polyethylene mesh used in the present invention is a 1.5 × 1.5 cm lattice mesh, the straw is in close contact with the vegetation ground to prevent the straw is scattered or lost by strong wind or rainfall. In particular, since the mesh is mainly applied to the inclined surface, it sufficiently supports the support load of the soil itself by external pressure in the installed state, and is caused by plant rooting during a certain period (about 1 to 3 months) when seeds germinate to introduce vegetation. Replaces pardon protection. In addition, the use of a green mesh can also be expected to have a landscape effect that keeps the green aesthetics from appearing right after construction. The mesh can vary the size of the mesh (between knots and knots) according to the characteristics of the place where it is installed.If the slope is steep, there is a risk of soil loss or the slope length is long, and the support load of the soil itself needs to be dispersed. Relative to the net can be utilized in a denser way than otherwise.

3 is a sectional view in which the green net of the present invention is provided on the slope.

According to the present invention, it is possible to maintain seed germination evenly by preventing seed tipping or loss caused by rainfall or strong wind, as well as promoting early germination and initial growth of seeds by continuous moisturizing and auxiliaries. The construction cost can be reduced because there is no need to re- or reconstruct, and the construction method is very simple to increase the unit construction amount. Unlike the general greening method, the construction itself is a buffering effect of slope infiltration water by the straw and polyethylene mesh. By inducing the dispersing action of the support load by the can ensure the stability of the slope.

Hereinafter, the present invention will be described in more detail based on the following examples. However, the following examples are only for illustrating the present invention, and the scope of the present invention is not limited thereto.

Example

With respect to the fill slope, bone was formed so that the bone width was 5 cm, the bone depth was 3 cm, and the bone spacing was 30 cm, and then 85% by weight of the organic compound, 7% by weight of lime, 1% by weight of the seed and 7% by weight of the compound fertilizer Mixed organic sachets were placed. Next, spread 25 g of seeds per unit area (m ² ), 250 g of coating curing agent, 100 g of erosion stabilizer and 100 g of compound fertilizer over the entire surface using a spreader, and then straw and polyethylene mesh (1.5 × 1.5 cm lattice net) on it. Moving the synthesized structure from the top to the bottom was installed so that the green mesh is visible to the outside. The connecting part between the net and the net was firmly fixed at an appropriate position by using one fixing pin (φ10, 20-35 cm in length) per 1 m ² while allowing the polyethylene mesh edges to overlap each other. Initial germination, moisturizing properties, slope stability and visual effectiveness, coverage and saturnal status of vegetation soils were observed for 60 days after construction.

Comparative example

On the same slope as the above embodiment, 25 g of seeds, 250 g of coating curing agent, 125 g of erosion stabilizer, 100 g of complex fertilizer, and 2 g of pigment were sprayed over the entire surface using a spreader. In the same manner as in the above embodiment, the initial germination, moisturizing power of the vegetation ground, slope stability and visual effectiveness, coverage and the soil state of the vegetation ground were observed for 60 days after construction.

1) Early Germination

In the examples, initial germination was observed after 5 days, and the comparative example was observed after 12 days. The growth state was also irregular, while the example showed that the plant growth rate or coating state was almost constant from the initial germination, so that the proper moisture required for the initial germination and It was found that the soil temperature was maintained continuously.

2) Moisturizing power of vegetation ground

After 10 days, each sample was taken and soil moisture was measured by soil analysis (constant temperature 20 ℃, humidity 50%). As a result, 92.5 (% / hour) for the example and 63.5 (% / hour) for the comparative example. In the example using the green net, the water vaporization amount was found to be reduced by 45% or more. This indicates that the green net of the present invention, as well as the conservative power of the soil itself, prevents evaporation of soil moisture as well as water content.

3) slope stability and visual effectiveness

In the case of the embodiment, the structure of the present invention was firmly adhered to the ground by polyethylene mesh, and almost no loss of seeds due to strong wind or rainfall occurred during the 60 days after construction, and thus it was preserved as it was sprayed. Neither was observed. On the other hand, in the comparative example, the soil or seeds were lost, the installation was damaged, and reconstruction was required.

In addition, the embodiment maintains the landscape effect such as greening even before the plant is settled by using the green mesh.

4) coverage

Table 2 shows the results of comparing the coverage ratios closely related to the fertility of the soil according to the number of days.

As can be seen from Table 2, the Example showed a significant difference with the comparative example over time in the coverage, and showed a coverage of 98% after 60 days of construction. 4a and 4b are photographs showing the vegetation state after 45 days of construction in the Examples and Comparative Examples, respectively.

5) Saturn in Vegetation Soil

After 30 days of construction, the soil samples were taken from each of the examples and the comparative examples, and the results of the test analysis are shown in Table 3 below.

division pH (20 ℃) Organic matter Total nitrogen P ₂ O ₃ (effective phosphoric acid) Mg (substitutable) K (substitutable) Ca (substitutable) unit - % % ppm me / 100g me / 100g me / 100g Example 6.80 14.32 1.02 154.7 2.17 0.58 8.62 Comparative example 5.20 3.50 0.68 105.5 0.27 0.50 1.25

As can be seen from Table 3, the soil samples collected from the examples contained more than four times more organic matter than the comparative example, and the difference in the component analysis of the soil samples of the examples and the comparative example is different from those of the plants shown in Table 2 above. It is closely related to coverage.

According to the greening method using the green net of the present invention, it is possible to maintain the germination distribution evenly by preventing seed tipping or loss caused by rainfall or strong wind as well as promoting early germination and initial growth of seeds by continuous moisturizing and holding power. The construction cost can be reduced because there is no need for additional seeding or re-construction, and the construction method is very simple to increase the unit construction amount, and unlike the general greening method, slope penetration by rice straw can be achieved by the construction itself. The stability of the slope can be ensured by inducing the buffering action of the water and the dispersion of the supporting load by the polyethylene mesh.
