In addition, it is possible to continuously maintain the moisture to assist the growth of ecological restoration plants, to prevent cracks appearing after construction of the vegetation base material composition for slope recovery and to improve the adhesion.

The artificial soil includes compost material.

Since the compost material uses natural material waste, it has high recycling of resources, and it can continue supplying organic nutrients because it can progress the housing process in artificial soil, and can provide adequate moisture, Can increase survival rate.

The compost material comprises organic waste.

The organic waste is generated from homes, restaurants, and the like, and food waste from which foreign substances such as vinyl and packaging materials with low degradability are removed. The food waste may be a dry or wet mixture, and in particular, the food waste may be a desalted, dehydrated, finely crushed mixture, and may preferably be compost that has been lodged for several days at high temperature. The desalination / dehydration and composting method of the food waste is not particularly limited.

The food waste can provide nutrients to the ecological restoration plants for a long time because the decomposition process in the artificial soil, the growth of the ecological restoration plant by the salt contained in the food to use the desalted food waste This can be prevented from being inhibited, and soil contamination by salt can be reduced. In addition, it is highly recyclable resources to use food waste, it is possible to prevent the early depletion of nutrients by not using organic fertilizer made of food waste. In addition, the recycling of food waste can be used without a fertilizer process, thereby reducing the cost of recycling, as well as preventing the addition of chemicals processed during the fertilizer process, thereby preventing environmental pollution.

The organic waste may be included in 5 to 50% by weight relative to the artificial soil, if less than 5% by weight it is difficult to provide sufficient organic nutrients to the ecological restoration plants, and if more than 50% by weight of excess organic waste Due to this, the balance of organic / inorganic nutrients in artificial soil may be impaired or the cohesion of artificial soil may be lowered.

Can be provided.

By using the masato, the breathability and drainage is improved, so that rainwater is collected during the rainy season, thereby preventing the anaerobic decay of the compost material and the roots of the plant for ecological restoration. Finally, cow dung and peat can be used to provide inorganic nutrients, such as inorganic nitrogen, and improve bovine strength and water retention. It is also possible to provide a habitat for microorganisms in the vegetation-based layer.

More specifically, the blended soil may include 5 to 30% by weight of clay, 5 to 20% by weight of masato, 5 to 20% by weight of dairy, and 5 to 20% by weight of peat.

When the content of the constituent soil is out of the constituent content of the soil, the granulation of the soil may be lowered, and phenomena such as cracking may occur due to the deterioration of the soil drainage and the binding force.

In addition, the artificial soil may further include a residual amount of water selectively.

Soil adhesive

Ecological restoration vegetation base composition according to the present invention comprises a soil adhesive. The soil adhesive is eco-friendly and can increase the adhesiveness of artificial soil without adding chemical components such as polymer adhesives, and can prevent the loss and cracking of artificial soil at the time of initial restoration.

It can prevent the detachment of ecological restoring plant and reduce the possibility of loss or fall of vegetation base material because it increases the adhesion with wire mesh or net at the slope. In addition, by using the mixed soil occupants and artificial soil, it can be applied directly to the wire or net network without the need to construct a layer of vegetation base material can simplify the ecological restoration method.

The soil adhesive may include clay and natural minerals, and in particular, clay may be uniformly mixed with the artificial soil, and cement may be used to improve adhesion of the vegetation base composition for ecological restoration with wire mesh or slope. Zeolite has a lot of nutrients to improve the nutrients of artificial soil, and bentonite contains moisture for a long time to improve the moisturizing effect.

More specifically, the soil adhesive may include 5 to 50% by weight of clay, 5 to 20% by weight of cement, 5 to 20% by weight of lime, 5 to 30% by weight of zeolite, and 5 to 30% by weight of bentonite. When the content of the constituents of the soil adhesive is out of the above range, the adhesion of the vegetation base material is lowered, such that the separation of the vegetation base material may occur. In addition, the soil adhesive may further include a residual amount of water selectively.

Vegetation-based Plant

Vegetation-based material composition for ecological restoration according to the present invention can be mixed with vegetation-based plants. The vegetation-based plant is an ecological restoration plant, and may include native seeds and foreign seeds. The vegetation-based plants can improve the greening rate during the initial slope recovery by using foreign seeds with high growth rate, and at the same time, harmonize with the surrounding environment using conventional seeds inhabiting the slopes to induce ecosystem conservation. .

Japanese swallowtail, rhododendron, azaleas, ginseng. It may be a native wood or herbaceous seed, such as blue-green / blue-vines, lychees, birds, alders, birch, linden, pine, maple.

The foreign seeds may be herbal seeds such as Turf Type Tall Fescue, Perennial Ryegrass, Orchardgrass.

The present invention provides an ecological restoration method using the vegetation base material composition for slope recovery.

The ecological restoration method includes the steps of installing a wire mesh or a network, forming a vegetation base material composition for slope ecological restoration, mixing the seeds and mounting on the slope.

The step of installing the wire mesh or the net is a step of removing foreign matters such as garbage on the slope, and installing the wire mesh or net. The slope may be a slope caused by natural disasters such as mountain slopes, floods, landslides, etc., which are artificially damaged, such as houses, roads, quarrying sites, and forest road constructions. have.

The wire mesh may be attached after the pin to secure the wire mesh, such as an anchor pin or landing pin to the slope, or may be laid on the slope. The network may be a coir net / jute net or the like.

The step of forming the vegetation base material composition for slope recovery ecological waste is mixed with organic waste, vegetable materials, clay, masato, powder, and peat in a weight ratio to prepare artificial soil and clay, cement, lime, zeolite, and bentonite To prepare a soil adhesive by blending in a weight ratio. Finally, mixing the artificial soil and the soil adhesive to form a vegetation base composition for slope recovery ecological.

The vegetation base material composition for slope-side ecological restoration may be formed in a compounding ratio of artificial soil and soil adhesive 90:10 to 95: 5 (w: w). If the artificial soil is less than 90 in the compounding ratio, there may be a difficulty in supplying nutrients to the ecological restoration plant, if it exceeds 95 may be weak adhesive strength on the slope of the vegetation base material composition for slope recovery ecological The loss of vegetation infrastructure is highly likely.

Mixing the seeds is a step of mixing the conventional seeds and foreign seeds in the vegetation base material composition for slope recovery. The seed may be mixed with the conventional seed and the foreign seed at a blending ratio of 6: 4 to 9: 1 (w: w). If the native seed is less than 6, the greening may proceed rapidly at the initial stage of restoration by the foreign seed. In the long term, the number of foreign seeds increases and the effect of ecological restoration of the environment around the slope is insignificant, and when the conventional seeds exceed 9, the vegetation base material loss occurs during the rainy season. Stable growth of restoration plants can be difficult. The type of the foreign seed and the conventional seed may be variously selected in consideration of the soil state of the slope and ecosystem restoration of the surrounding environment.

The step of mounting on the slope is a step of attaching the vegetation base material layer on the slope by using the wetted method using dry or water in the vegetation base material composition for slope recovery ecological cotton mixed with the seed.

The mounting thickness of the vegetation base material layer may be 0.5 to 15 cm, the thickness may be appropriately selected according to the soil conditions of the inclined surface, preferably 0.5 to 6 cm.
