Description

Method for tree-planting cutting-side with Species Diversity Restoration

The present invention relates to a method for greening an incision site where diversity of local species is reconstructed, and more particularly, in consideration of the inherent ecological and landscape characteristics of the restoration area, the tree species which are similar to the ecosystems before the damage and the transitional to late to late species The present invention relates to a greening method that can be restored to a multi-layered vegetation structure composed of a multi-layered vegetation structure, that is, an incision greening method (hereinafter, referred to as SDR (Species Diversity Restoration) greening method) in which the diversity of local species can be restored.

In general, leaving inclined surfaces or incisions that can appear in various construction or development sites can damage the aesthetics and cause landslides or loss during the rainy or thawing seasons, and can result in human accidents. Accordingly, in order to stably protect the incision or the slope and provide an aesthetically superior atmosphere, and to restore nature, a method of artificially arranging the corresponding part of greenery is performed. Examples of such greening methods include sowing seeds in the incision and vegetation, incorporating seeds, fertilizer and soil into the incision into vegetation mats, and laying a wire net or net on the inclined incision and then artificial soil. And spraying to a predetermined thickness to create an artificial vegetation base, and the like.

However, most of the conventional greening methods such as inclined or sloped surface use introduced seeds, herbaceous, woody, etc. without considering the inherent ecological characteristics of local or restored areas. And poor growth, low germination rate, and poor adaptability.

In addition, since seeds and vegetation mains applied to the greening of the plant are not collected or supplied at or near the greenery, it is difficult to restore the local ecosystem, and it is impossible to create a natural landscape with the surroundings.

On the other hand, general seeds or imported seeds should be stored in a dry state at low temperature to prevent rooting and germination of the seeds. However, at present, most domestic seed importers and distributors or incision greening contractors have kept these seeds at room temperature under various conditions. As described above, when storing seeds at room temperature, the quality of the seeds deteriorates due to a large change in temperature and humidity according to seasons, resulting in a low germination rate, which makes it difficult to maintain a constant quality for a long time.

In addition, heat is generated at the same time as it is damaged by the respiration of the seed itself. The heat generated in this way tends to cause softening and deterioration of the seed, and there is a problem in that the moisture of the seed disappears due to transpiration and deteriorates. In addition, decay is caused by the action of microorganisms, or the quality is degraded by the infection of pathogens.

In addition, in reality, most seeds used for general incision greening rely on imports. These imported seeds are used in a large amount of seed disinfectant to prevent viruses, pests, etc. in the exporting country, so as not only to modify soil but also to change seeds. There is a problem that results in degradation of quality.

Recently, in order to solve or supplement the problems caused by the external introduction of seeds as described above, it is necessary to promote seed germination, called seed speeding system, but without special treatment before seed import. In most cases, the seeds are used after soaking in the tank for about one day, and there is a problem in that the seed, particularly the dormant seed, is hardly effective in addition to the seed that is easily penetrated into the peeled seed or the seed.

On the other hand, the conventional polymer resin has a problem that if the moisture does not evaporate after construction, the erosion prevention function is not exerted, and it takes a long time until a sufficient erosion prevention effect is obtained, and deterioration of the resin due to ultraviolet rays occurs.

Recently, various studies have been conducted on greening methods using local seeds and vegetation, which have high adaptability to the area and excellent ecological and landscape harmony with the surroundings. It is emerging.

Accordingly, the present invention has been invented to solve the problems and problems described above, the object of the present invention can be restored or recorded the same or similar to the local ecological environment and landscape environment before construction and the germination, vegetation and adaptability of the seed The diversity of local species that can be improved is to provide a resilient greening method.

In order to achieve the above objects, a variety of local species species according to the present invention is resilient recording method, the diversity of the local species for recording in harmony with the local ecological or landscape atmosphere such as legal or slope A method for recording a reversible incision (SDR recording method), the method comprising the steps of: securing an incision to be recorded and seeds of vegetation native to the periphery of the incision and external seeds similar to the seeds; Selecting seeds which are actually seeded or mounted in the incision to be planted among the secured seeds; Testing the early germination of the selected seeds; blending the seeds by mixing and designing the seeds according to the ecological environment set in the incision to be greened; Processing to maintain seed quality to ensure germination upon incision placement of seeds that have undergone early germination testing and mixed design; A germination promoting step for promoting germination of the seeds upon incision of the quality-treated seeds; Package-processing the germination-promoted seeds for feeding them into the incision recording site; Mixing the secured, selected and treated seeds to form a vegetation base material for attachment to the incision; The first vegetation base layer is formed by attaching the vegetation base material without seeds to the incision, and the second vegetation base layer is installed once without changing the equipment by installing the vegetation base material mixed with seeds on the first vegetation base layer. It is characterized in that the step of increasing the efficiency of greening.

As described above, according to the present invention, the incision recording method for restoring the diversity of the local species according to the present invention, that is, according to the SDR recording method, is suitable for the local atmosphere by the seed of the vegetation main plant native to the construction site or the same or similar seeds. By treating in the state and attaching by dry two-layer mounting method, the seed germination performance is excellent, local adaptability and vegetation ability is excellent, and the remarkable effect of optimal formation and maintenance of the original ecological environment and landscape harmony of the incision site will be.

In addition, it is possible to complete the greening having the best germination performance by one installation using one mounting device, thereby improving workability and productivity.

While a preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the appended claims.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, first, the SDR recording method according to the present invention secures the seed for recording the incision such as the slope or slope (S100).

In particular, the seed securing step (S100) is a herbaceous herbaceous seed that grows native to the area where the SDR greening method according to the present invention is to be implemented, that is, the construction of roads, the development of residential or industrial complexes, and the construction of revetments. It is preferable to collect directly. However, if direct seed cannot be secured due to timely or environmental factors, the site may be surveyed or sampled, the seeds of the same or similar herbaceous plants may be obtained around the area, or the area may be sampled. Seeds can be selected and introduced from outside and secured.

When the seed is secured as described above, the seed to be sown or mounted by the SDR greening method is selected in the region (S200).

The seed selection step (S200) investigates and considers the climate, surrounding vegetation, potential natural vegetation, landscape features, ecosystem conservation and restoration, etc. of the restoration area, and also slopes of soil or slope of the restoration area, soil hardness, and cancer cracking. It is desirable to investigate and consider the degree and the like.

In particular, when the vegetation is excellent in the region, and the condition for the above-mentioned surroundings is not only satisfactory, but also satisfies the contractor and the implementer, it is preferable to select as the herbaceous seed of the region or select some of them.

Further, in the seed selection step (S200), the SDR greening method according to the present invention is based on the standard type of the seed mixture design with the main component species of high frequency of main tree species, and selects one suitable for the construction area from among them. It is preferable. Of course, in addition to such a standard type, it is also possible to select seeds of a special type that can be used in a variety of constituent species to meet the surrounding environment or location characteristics. In this case, in the case of using a plant which is difficult to secure high quality seeds among the selected main constituent species or a plant which is difficult to be introduced in the sowing method, the planting method can be used in combination with the sowing method. Of course, it is preferable to use seedlings having a small maximum power so that the tree roots used in the planting method can be made to have good growth rate and growth after planting.

On the other hand, if it is determined that it is difficult to extract the herbaceous seed from or around the incision site such as legal or sloped surface, the seed of the herbaceous herbaceous vegetation is selected from the area having the atmosphere most similar to the relevant area, or It can be selected based on the concept of wood type, that is, biodiversity restoration type, which is best suited to the atmosphere. In addition, it is selected from the community close to the natural landscape of the region or the rich population, and based on the restoration and greening goal that emphasizes the preservation of the landscape and the ecosystem of the mountainous region, the principal species of the surrounding vegetation or the potential natural vegetation of the region is the main subject. It is preferable to select seeds on the basis of.

According to the practical embodiment for the selection of the seeds as described above, it is preferable to classify and select the main constituent species, conservation species and herbaceous species in order to achieve the restoration target. Here, the main constituent species are plants that are central to the forest formation for greening, have a nature close to the surrounding vegetation, and are the main constituents of the biodiversity colony targeted for restoration and greening. Most of the climax species or secondary constituent species are used, and generally two to four kinds are selected, for example, pine, gorse, redwood, oak, maple, and mountain bark. Conserved species, together with herbaceous species, improve soil physicochemical properties and fertilize soil, and relieve microclimates by growing above ground. One to three types are selected, for example, albizia julibrissin, alder tree, birch tree, mandarin duck, linden tree, sesame seed, locust, and wild duck. In addition, herbaceous species form the topsoil layer of the early stage to form the base of the ecosystem recovery, and to secure the initial greening or prevent erosion of vegetation-based materials, herbaceous herbs such as conventional herbs and foreign herbs introduced can be used and generally One to three kinds are selected, for example, non-repair, angocho, laver hair, tolsque skew, creeping red fesque, and perennial ligragrass.

When the selection of seeds is completed as described above, the early germination test of the selected seeds is performed (S300).

The early germination test of the seed is basically a method of selecting some of the selected seeds, placing a wet filter paper in the curry and arranging the seeds thereon, for example, at a constant temperature of 23 ° C., as illustrated in FIG. 2. Test or measure the germination using. This early germination test method is to set the condition that the seed is easy to germinate, and to promote the germination, germinate the seed in a short period of time (about 1 week), and evaluate the percentage of the seeds having germination capacity as a percentage. Obtain the result. In practice, seeds have different dormancy even if they are identical in appearance, such as primary dormancy, which is physiologically dormant, thick dormant that prevents the supply of water or oxygen, and the seed itself matures. Internally, however, the ship is classified as after-school dormancy, which is immature. Therefore, it is preferable to select and perform several kinds of treatment methods suitable for each seed according to the physiological characteristics, such as the type of dormancy listed above, and the structural characteristics of a seed. As described above, as a treatment method for testing early germination, it is preferable to be divided into pretreatment, denture treatment, and germination promotion treatment as follows.

First, pretreatment is a step for facilitating seed processing of the seed, soaking the seed in water for a predetermined time in advance to soften the seed or seed tissue. Then, in order to improve the germination of seeds, the seeds are purified, sterilized, and oils and fats are removed. In more detail, in order to suppress the development of the mold during the test to remove the pulp and the like through the seed purification method, or the seed is susceptible to mold is pre-sterilized. It also removes the oily components of the seed coat to promote oxygen and water supply into the seed. Of course, such pretreatment can be selectively performed according to the characteristics of the seed.

Next, the tooth treatment is the core of the early germination test, and the seeds are processed in a state where they are likely to germinate using a plurality of methods appropriate to their characteristics, and are disposed on a filter paper placed in a curry. Such tooth treatment can be performed by removing the seed, cutting the seed tissue, thinning the seed, or cutting the seed, based on the structural and physiological characteristics of the seed. In some cases, cutting may be performed in parallel. For example, the important factors for seed germination include oxygen and water, and the first tissue to start growth in the tissue of the seed when the seed germinates is the axial tissue. It is to promote the supply of oxygen and water into the shaft tissue by removing, thinning, wounding or cutting the seed tissue itself, which inhibits the supply of oxygen and water into the tissue. Through this method it is possible to determine the seed quality in a shorter time than the conventional germination test.

The germination promoting treatment is highly dormant, and it is easy to process seeds which are difficult to process due to their own structural problems, such as seeds which do not germinate within a period of about one week even with the tooth treatment method described above. It is the processing method to carry out. As the germination promoting treatment, there is a method of adding plant hormone, adding a germination promoting substance, or flocculation under high pressure oxygen. Here, the method of adding phytohormones or germination promoters may be selected according to the germination pattern of the seed, by adjusting the concentration of the substance to be suited to the degree of dormancy or the size of the seed, or by mixing various kinds of substances. Can be used. For example, 0.2% KNO3 and Thiourea solution may be used as a germination promoter (dormant breaker), or 100 ppm Gibberellin solution may be used. In addition, the method of flocculation under high pressure oxygen is a method of flocculation under high pressure oxygen by injecting high pressure oxygen after putting the curry with seed into a completely sealed container such as a desiccator. How to promote it. Such treatment may also be used in combination with plant hormones and germination promoters depending on the degree or state of dormancy of the seed.

However, the early germination test method is used only when it is difficult to achieve germination only by the germination power of the seed itself, and it is desirable to suppress germination promoting treatment and obtain germination promotion only by tooth treatment as much as possible. Use the promotion method.

On the other hand, when the treatment as described above is performed, the germination force can be tested or evaluated in order to confirm the result of such treatment. Such an evaluation of germination can be obtained by expressing the percentage of individuals exhibiting germination symptoms at the end of the early germination test and the total population in percentage. At this time, the symptoms or results of the germination appear different depending on the germination characteristics of the seed or the treatment method of the seed, and the method of determining that the germination symptom is indicated depending on the situation. This criterion is based on the number of individuals whose young roots or axial tissues protrude from the kidneys or seed tissues, the number of young roots or axial tissues in the direction of gravity, and the cotyledons of the cotyledons. Germination can be evaluated by considering the number of swollen individuals, the number of chlorophyll-forming and greening of cotyledon tissues, and the number of individuals with irregular roots. Of course, such germination evaluation is preferably carried out at the end of the germination test, but generally the test period is within one week. However, dormant seeds require more than one week of testing.

The seed selected as described above is actually seeded according to the mixed design set to be optimally adapted to the ecological environment or atmosphere of the site to be mounted (S400). Optionally, the seed may be applied to a seed that is different from the standard type when the seed is selected so that the restoration target is effectively achieved by the environment around the construction site, the request of the implementer or the client, or the importance of locality. In some cases, the seed may be selected through a design suitable for the site.

According to the seed blending design, the seeding ratio is determined according to the restoration target of the restoration area, and the seeding rate is based on the baseline number of generations.

 W = A B × C × D × E × F × G

It is preferable to determine by.

In the formula, W is the seeding rate per seed (g / ㎡), A is the number of generation bases (bone / ㎡), B is the correction rate by the thickness of germinating cover for the mounting thickness, and C is the SDR for the location conditions. The correction rate of the greening method, D is the correction rate for the time of construction, E is the germination rate or early germination test value of the seed used, F is the unit intake (lip / g) of the seed used, G is the net rate of the seed used to be.

Here, the generation baseline number A is the number of generations required to form the target group, which represents the total number of individuals that occur in one year after the seeding, and of course, a value including the number of deadly dies by blood pressure or the like.

The correction rate (B) by the germinating thickness of the cover to the thickness of the plant is significantly different by the difference of vegetation-based material and the germination and growth of the plant. The method is based on the germination thickness of the germinating seed of the seed. The correction rate by the germinating cover thickness for the mounting thickness is based on the following <Table 1>.

Germinating thickness Mounting thickness of vegetation base material 3 cm 5 cm 7 cm 10 cm 0.5cn 0.17 0.10 0.07 0.05 1.0 cm 0.33 0.20 0.14 0.10 2.0 cm 0.67 0.40 0.29 0.20 3.0 cm 1.00 0.60 0.43 0.30

The correction rate C for the location condition is set in accordance with conditions such as soil quality, slope, and orientation of the slope. Such correction rate is based on the following <Table 2>.

Item Location condition Correction rate Slope slope ≥50 ° 0.9 〈50 ° 1.0 Soil Hard rock 0.9 etc 1.0 Slope bearing Gyeongam (South) 0.8 etc 1.0 Precipitation 〈1,000mm 0.7 ≥1,000mm 1.0

Although it is desirable to avoid the construction of the inappropriate period, the correction rate (D) of the construction time should be corrected for the construction time when the construction is inevitable, and such correction ratio is based on the following <Table 3>. .

Construction time Herbaceous plant Woody plant March ~ June 1.0 1.0 July ~ August 0.8 0.7 September 1.0 0.5 October-November 0.7 0.5 November-February 0.9 0.8

The germination rate (D) or early germination test value of the seed used, especially since the germination rate varies greatly depending on the harvesting year and storage condition, use the germination rate or early germination test value of the previously investigated seeds, and the germination rate is 90%. In the case of 0.9.

As the germination rate, the unit acquisition (E) of the seed used varies greatly depending on the harvesting year, so use the unit acquisition that was previously tested in the design. In addition, because the SDR greening method uses naturally collected seeds, it is possible to measure the number of unit in the state in which the contaminated water is mixed depending on the type.

The net yield (G) of the seed used shall be used as it is for seeds with a clear net yield, and the correction value shall be 0.95 for 95% purity. However, the seed collected naturally is calculated as 1.0 since it is already corrected in the unit water.

On the other hand, in the case of general seeds or imported seeds obtained outside the construction site is processed to maintain the quality of the seeds for smooth germination during installation (S500).

This seed quality maintenance step involves the removal of the seed disinfectant from the imported or externally procured seeds, primarily by physical methods, and the remaining residual disinfectants by secondary chemical methods, followed by storage at a low temperature storage warehouse. It is stored in a step of storing without degrading the quality of the seed.

There is also a quality maintenance method using a porous inorganic material in consideration of the properties of the seed optionally.

As described above, in the case of using a porous inorganic material, the seed quality protective material including the porous inorganic material is mixed with the seeds, so that the proper humidity is maintained by adsorption and breathability peculiar to the porous inorganic material having fine pores, so as to adsorb and sterilize harmful gases. It is possible to eliminate germs and germs. In addition, the porous inorganic materials contain useful soil bacteria such as seed quality protective materials, thereby suppressing the decay of seeds, and suppressing soil pests, improving physiological activity, improving fertilizer utilization of plants, and consolidation of roots, even after sowing. It is expected to work.

A representative porous material is zeolite, which consists of porous hydrous aluminocayte minerals composed of SiO2, Al2O3, CaO, Na2O, K2O, H2O, and the pore diameter is formed by ultra fine pores of about 4 ~ 7Å. It is preferable to be. The porous material made of zeolite may serve as a soil improver because of its characteristics such as adsorption, absorbency, and base substitution capacity. In other words, the high adsorption and base substitution capacity prevents the loss of fertilizer, improves the binding force, and improves water retention and harmful gas adsorption. In particular, it has the function of disinfecting pathogens and inhibiting the activity of anaerobic bacteria due to oxidation in the presence of water. Due to the characteristics of zeolites, when stored mixed with seeds, the seeds can be kept at a suitable humidity and ventilation can be secured, and they can adsorb harmful gases such as ethylene, hydrogen sulfide, and ammonia, and they are non-toxic. Because it can be ignited, sterilized, or sterilized, the seed can be prevented from drying out in the end, and decay can be suppressed to ensure excellent quality and germination rate of the seed. On the other hand, as a porous material having a similar function to the above-described zeolite, and can be applied equally to the present invention, there are diatomaceous earth, fired product, antibacterial ceramic, pearlite, vermiculite and the like.

After the quality maintenance treatment of the seed as described above, the seed is treated so as to actually promote the germination of the seed (S600).

The seed germination promoting step (S600) is preferably using a seed germination promoting system (Seed Speeding System) to be applied to the SDR greening method according to the present invention, a sufficient water supply for germination or strong dormancy Seeds are treated to promote germination before construction, and if necessary, a germination promotion pack is used. By using the seed germination promoting system as described above, germination can be promoted by physically and chemically preventing the seed dormancy.

The method of promoting germination in more detail, first, the oil and germination inhibitors attached to the seed of the seed using a chemical agent such as sodium hydroxide, hydrochloric acid, sulfuric acid (seeds), calcium peroxide (oxygen supply agent), etc. Remove (chemical treatment). Thereafter, the seeds are subjected to epithelial waves, that is, the seeds are physically damaged by hitting or rubbing the seeds together, and then treated with shaking, hot water, dry heat, low temperature, high pressure, and the like (physical treatment). Finally, indole acetic acid, gibberellin, cytokinin, florigen for the regulation of various physiological changes in the seed when it is mounted in a place different from where the seed was obtained. ), Plant hormone treatment using hormones such as Abscisic acid (plant hormone treatment). The plant hormone treatment can prevent the dormancy of seeds caused by the dormancy of the pear and various other causes and promote germination.

After germination promotion treatment of the seed as described above is actually packaged to be put into the construction site (S700). Germination promoting packs are used for packaging such seeds.

The seed package treatment step (S700) may be performed by mixing 70 to 85 parts by weight of the seed-promoting seed and 15 to 30 parts by weight of terra cottem (Terra Cottem), which is a super absorbent polymer, and encapsulating it in a waterproof pack. . Here, the terra cotem has excellent absorbency for absorbing water up to 200 times its own weight, and thus it is possible to continuously supply moisture to the seeds in the swollen state. Accordingly, the seeds are always supplied with an appropriate amount of moisture in the germination promotion pack, so that the germination promotion can be completed during the construction site movement, and even in the case of seeds which require a lot of moisture for germination, do not supply water after construction. Or germination can be promoted early, even if it is not raining.

After securing, selecting, and comprehensive treatment of seeds in the above manner, vegetation foundations are formed or prepared to form vegetation foundations on the legal or slope side of the construction site where the treated seeds are actually mounted and sown (S800). . The vegetation base material applied to the vegetation base composition of the SDR greening method according to the present invention is formulated and blended suitably for the germination and vegetation of seeds of various plants, from herbaceous plants to tree roots constituting the finest, to finally improve the environmental resilience It is preferred to be configured.

The vegetation base material in the SDR greening method according to the present invention is environmentally friendly, has excellent hardness, acidity and cation substitution ability, and can suppress excessive growth of the herb when the mixed seeding of the herb and the wood containing appropriate nitrogen, and transition It is preferred to be formulated or constituted on the basis of the principle of optimally containing the organic matter forming the plant colony of the medium to late stage (top).

Based on the basis of such a configuration, the vegetation base material composition of the SDR greening method according to the present invention is 20 to 30% by weight Bark compost, 10 to 15% by weight peat moss, 15 to 25% by weight as a stock raw material Peat, 10-20% by weight of purified sludge, 10-20% by weight of mixed compost, 5-10% by weight of vermiculite, 2-5% by weight of granules (Geo-binder), 0.2 0.5-% by weight of the tree-controller and 0.5-1.0% by weight of microorganisms.

The vegetation base material according to the present invention applied to the SDR greening method is environmentally friendly, has excellent hardness, acidity, and cation substitution ability, and can suppress excessive growth of herbs when mixed seedlings of herbs and wood containing appropriate nitrogen, It is preferable that it is comprised based on the principle that it optimally contains the organic substance which forms the plant colony of the medium to late stage (superfine) of a transition stage.

The bark compost of the above components is a fine grinding of the cortex of the conifers or deciduous trees, and is added for the maintenance of the seed to maintain a constant vegetation and growth. When the bark compost is less than 20% by weight of the total vegetation base material, the fertility is reduced, affecting the vegetation and growth of seeds, while more than 30% by weight may cause necrosis of seeds or plants due to the supercharging of the impact. .

Among the components, pitmoss is an organic substance having a large base substitution capacity and a strong acidic acid deposited in an anaerobic state, and is added to improve the retention of nutrients to maintain seed germination and vegetation. When the pitmos is less than 10% by weight, the retention capacity is reduced, affecting the vegetation and growth of the seeds, while more than 15% by weight may cause necrosis of the seeds or plants due to nutritional supercharging.

Also, among the components, peat is organic chemically carbonized due to deposition of aquatic plants, moss, grass, etc., and includes organic matter, and has high porosity, and is added to maintain seed germination and vegetation by improving absorption or hygroscopicity. It is. The peat is less than 15% by weight causes a delay in the germination of seeds due to the lack of water supply, while more than 25% by weight of the peat may cause necrosis of the seed or plant and cause sliding.

* Also, the purified sludge among the components may be plastically processed as sludge generated during the purification of tap water, and does not include foreign substances and germs, and has excellent drainage power and low pollution, so that seeds are stably maintained and germinated. At the same time, excessive weight is added so that the sliding of the land does not occur. When the purified sludge is less than 10% by weight, the seeds may not be able to germinate and maintain stably, and when the amount is more than 20% by weight, water supply may be insufficient due to excessive drainage.

In addition, mixed compost among the constituents is insufficient nitrogen and carbon components when the vegetation base is attached, so that the germination and growth rate of the seed is not slow and at the same time, the germination and growth rate of the seed is too fast, resulting in a dense phenomenon of grass or vegetation. It is added so that the reoccurrence rate does not fall. When the mixed compost is 10% by weight or less, the germination and growth of the seed is delayed, and when 20% by weight or more, necrosis may occur due to early germination and over-maturation of the seed.

In addition, vermiculite of the above components is added so that there is no loss or loss of breathability and drainage when mounting the vegetation base material, and at the same time there is no cracking or strong alkaline to cause difficulties in vegetation . If the vermiculite is less than 5% by weight may result in loss of seeds, and if more than 10% by weight, cracking may occur due to excessive drainage.

In addition, the granulation agent and the polymer additive of the above components are added so that they are not easily lost due to the lack of cohesiveness when the vegetation base is attached, and the solidification is increased and the breathability is lowered so as not to inhibit germination and growth of vegetation. will be. The granulation agent is less than 2% by weight may result in loss of vegetation base material due to lack of cohesion. If it is 5% by weight or more, air permeability is lowered, which may adversely affect the germination of seeds and the growth of vegetation.

In addition, the plant growth regulator of the above ingredients to achieve the nutrients can be eluted to suit the plant growth characteristics of fast growing plants and slow plants, if less than 0.2% by weight growth due to lack of nutrient dissolution It may cause a delay, and if it is more than 0.5% by weight can be over-mature due to the excessive dissolution of nutrients.

In addition, the microorganisms of the above components are added to maintain the oxygen supply and eutrophication of the vegetation base material. When the microorganism is 0.5 wt% or less, it may interfere with respiration of the vegetation base material, and when it is 1.0 wt% or more, it may cause acidification.

Optionally, the vegetation base material according to the present invention is composed of 40 to 50% of solid phase, 20 to 30% of liquid phase and 20 to 30% of gaseous phase, growth of plants, absorption of moisture and inorganic components, oxygen supply, etc. It is desirable to keep it smooth and excellent.

In addition, the soil hardness of the vegetation base material applied to the SDR greening method according to the present invention is related to various factors such as particle size composition, porosity, filling density, soil moisture content, etc. as an indicator of soil cohesion and friction between particles. Hardness, which is an index related to growing plants, is preferably maintained at 18 to 25 mm. If the hardness is 18mm or less, the growth of the plant is possible, but there is a risk of collapse of the legal or slope surface, 25mm or more may prevent the collapse of the slope surface but the activity of growth may become impossible.

In addition, in the case of the vegetation base material as described above, in order for the plants to grow normally, pF1.8 ~ 3.0 (l / ㎥) in the range of effective moisture (between counterfeit coefficient tension and packaging water tension) was found to be pure water. If the effective moisture is less than pF1.8, seed germination may occur due to lack of moisture moisturization, whereas moisture above pF3.0 is difficult to grow plants due to moisture in a range where plants cannot use water due to capillary action. Can be.

On the other hand, according to the chemical properties of the vegetation base material as described above, promotes the formation of the vegetation base material to improve breathability and water retention, increase the cation substitution capacity, maintain the supply and storage of nutrients, and provide the activation of soil microorganisms In order to maintain the organic matter of 25 ~ 35g / kg is preferred. If less than 25g / kg may cause nitrogen starvation, 35g / kg or more may cause side effects such as unbalanced accumulation of nutrients and over-accumulation of salts.

In addition, it is preferable to maintain the phosphoric acid of 200 ~ 300mg / kg for the vegetation base material in order to prevent the lack of phosphoric acid by the change of the vegetation base material to acidic.

In addition, it is desirable to maintain 40-70 mg / kg of nitrate nitrogen (NO3--N) for the vegetation base material in order to maintain the nitrogen which can be used by plants as well as the nitrogen for the soil microorganisms in the vegetation base material. .

In addition, it is preferable to maintain 0.3-0.6cmol + / kg of potassium and 1.5-2.0cmol + / kg of replaceable magnesium for the vegetation base material so that the vegetation base material can be easily absorbed by the plant when it is weakly acidic.

In addition, it is desirable to maintain a Cation Exchange Capacity (CEC) of 6-20 mmol + / kg in order to increase the fertility and fertility of the vegetation base material. Here, the cation substitution capacity is the positive and negative ions of the inorganic nutrients in the soil. The cationic nutrients are clay particles (Silicate and aluminum oxide) and organic matter in the soil that have a negative charge on the surface. It means the ability to be adsorbed and stored by means of, and it is a measure of soil fertility.

In addition, it is desirable to maintain the soil acidity of pH 6.0 ~ 6.5 to ensure the chemical reaction of the vegetation base material and the activity of soil microorganisms, and easy absorption of various essential components.

In addition, it is preferable to maintain the electrical conductivity of 0.5 ~ 1.8dS / m to maintain the proper salt as an indicator of the salt concentration contained in the vegetation base material. If the electrical conductivity is 0.5 dS / m or less, nutrients are required, and if 1.8 dS / m, salts should be removed.

In particular, the SDR composition (vegetation-based material) applied to the SDR greening method according to the present invention includes a plant growth regulator (Tree Controller) to provide nutrients suitable for the growth characteristics of the plant. The plant growth regulator is composed of nitrogen, phosphoric acid, potassium and magnesium. The ratio of each of these components, that is, the ratio of nitrogen: phosphoric acid: potassium: magnesium: is mixed in a ratio of 6: 40: 6: 15, and the component elution composition is nitrogen (10% fast, 90% slow), phosphoric acid (10% fast). It is preferable that the composition is composed of 90% of slow efficacy), potassium (65% fast and 35% slow) and magnesium (8% fast and 92% slow). Here, when nitrogen is insufficient, the growth of the leaflets is reduced and the color of the leaves appears in pale yellow, whereas when the tissue is excessively coated, it is preferable to be set in the range of 6 to 12 parts by weight because it is easy to cause pests and cold resistance is also lowered. Phosphoric acid deteriorates the growth and growth of the root and ground areas, but it is preferable to set it in the range of 38 to 62 parts by weight since excess may cause short-lived due to over-maturation. It promotes assimilation, physiological action to compensate for lack of sunlight, strengthens stems and leaves, increases resistance to pests, and prevents painting, cold, and drought. Participate in the metabolism system to increase resistance of enzymes and indirectly promote metabolism to resist It is preferably set in the range of 6 to 12 parts by weight, and magnesium is a metal element constituting chlorophyll, which is an essential component for photosynthesis, and is generally accumulated in young cells or metabolism-rich tissues, and chloroplasts are generated when they are insufficient. Since the plant turns yellow because it cannot be, overgrowth can cause necrosis and growth of root and stem growth and maturation of seeds can be inhibited, so it is preferably set in the range of 14 to 24 parts by weight.

Optionally, the plant growth regulator as described above may be set in consideration of the growth characteristics of the vegetation group to be restored, the utilization rate of the essential nutrients of plant growth, the effect period of the nutrients.

On the other hand, the duration of the nutrients of the plant growth regulator composition as described above is preferably set to at least 150 days or more to continuously supply the amount of nutrients required by the plant during the growth period.

In addition, the dissolution rate of the plant growth regulator configured as described above was tested at a temperature of 25 ℃ to obtain the following results.

  <Table 5> Dissolution Rate of Plant Growth Regulators in Water

As can be seen from Tables 4 and 5 above, in the plant growth regulator according to the present invention, nitrogen, phosphoric acid, potassium, and magnesium were gradually eluted with time, and then supplied to plants.

In addition, it can be seen that the electrical conductivity of the plant growth regulator is changed as shown in Table 3.

<Table 6> Graph of electrical conductivity change of plant growth regulator

As can be seen from the graphs of Tables 5 and 6 above, the electrical conductivity of the plant growth regulator was maintained almost uniform after a month to ensure a stable growth of the plant.

In addition, it can be seen that the change rate of acidity after construction is changed as shown in the following Table 7.

Table 7 Graph of Changes in Acidity of Plant Growth Regulators

In particular, comparing the initial dissolution rate of the plant growth regulator according to the present invention shown in the above table with the initial dissolution rate of the general complex fertilizer and slow-release fertilizer commercially available as shown in the following Table 8 and Table 9.

<Table 9> Comparison of initial dissolution rate of plant growth regulator and general fertilizer

In addition, after testing the vegetation base material containing the general compound fertilizer and the vegetation base material containing the plant growth regulator applied to the SDR greening method according to the present invention and observed the growth state of the herbaceous, as shown in the photo of Figure 3a As shown, while the general compound fertilizer was used, yellowing occurred 2 months after construction, while the yellowing phenomenon was not generated in the vegetation base material including the plant growth regulator as shown in the photograph of FIG. Appeared. This can be understood that the dissolution of the plant growth regulator contained in the vegetation base material according to the present invention is made continuously and stably, as well as the initial dissolution of nitrogen and phosphoric acid causing yellowing phenomenon.

In addition, the SDR greening method according to the present invention has a granulation agent (Geo-binder) for the prevention of erosion and loss of vegetation base material by rain and wind during the period before the wood sticking, and the improvement of physical properties according to the formation of vegetation base material It is essential to be included.

The granulating agent is a powder such as fly ash, tuff, blast furnace slag having a pozzolanic reaction of 150 µm or less, gypsum, lactates such as sodium lactate, potassium lactate, magnesium lactate, sodium hydrogen lactate and potassium hydrogen lactate. It is preferable to be formed of a geobinder to form a strong erosion-preventing effect and a high-order granular structure of a mixed mixture of heavy lactate, such as magnesium hydrogen lactate. Here, the pozzolanic reaction is a silica mixture, which itself is not hydrophobic, but chemically reacts with water to combine with lime to form an insoluble silica compound. When contacted with water, trace amounts of calcium and silicic acid are eluted to form the particles. It is a reaction in which amorphous silica and alumina hydrate are produced together with insoluble dense hydrate. By applying this pozzolanic reaction to the vegetation base material, it prevents the loss by erosion or freezing by strengthening the erosion resistance through condensation and solidification of the vegetation base material, and the powdery and spherical pozzolan reaction powder forms the microporous tissue layer to form By acting as a granulation agent to improve the water retention, breathability, etc. of the ash, it can play a role in creating a physical environment favorable to the germination and growth of plants. As a result, the granulation agent is easy to handle because it does not generate latencies even when excessive moisture is present and there is no fear of excessive curing, and exhibits a pH range suitable for plant growth, thereby promoting good germination and growth of vegetation. .

The granulation agent is composed of 31 to 33 wt% CaO, 29 to 31 wt% SiO ₂ , 9 to 11 wt% Al ₂ O ₃ and 29 to 31 wt% SO ₃ .

The change in soil acidity after the construction of the vegetation base material including the granulation agent configured as described above is shown in Table 10 below.

* Table 10 Changes in soil acidity (pH) after construction of granulation agents

    division Composition 12 days later 38 days later 84 days later Geo Binder 7.5 5.8 5.9 5.8 Mineral 8.9 8.5 8.4 8

As can be seen in Table 10, the acidity is maintained at a significantly lower level than the conventional inorganic mineral granulation agent, thereby promoting good germination and growth of the vegetation attached to the entire vegetation base material.

On the other hand, in order to test the erosion resistance of the granulation agent configured as described above, the inclined surface of the artificial slope of 1m in width and 1m in size at an angle of 45 degrees, the untreated vegetation base material, and the granulation agent available on the market With the vegetation base material included and the vegetation base material containing the granulation agent applied to the present invention at a thickness of 5 cm, the vegetation base material was lost after applying artificial rainfall for 12 hours with 100 mm / hr precipitation. After drying for 24 hours in a 100 ℃ dryer erosion resistance measurement results are shown in the graph of Table 11.

 Table 11 Erosion Resistance Test Results

As can be seen from the graph of Table 11 above, the loss of the amount of 115-137g was large and the erosion occurred in the test group without using the granulation agent. On the other hand, the particle size (Geo-Binder) applied in accordance with the present invention is 13 ~ 17g loss amount is well maintained the stability of the vegetation base material, the deviation was also small.

On the other hand, as shown in Figure 4, the vegetation base material containing the granulation agent according to the present invention is more densely and firmly granulated than the case of the vegetation base material containing the general soil and general granulation agent does not contain the granulation agent Achieve.

In addition, as shown in Figures 5a and 5b, the vegetation base material (Fig. 5b) containing the granulation agent according to the present invention and commercially available vegetation base material (Fig. 5a) commercially available under the same conditions 30 When one day has elapsed, the vegetation base material according to the present invention is significantly less physical properties such as erosion prevention than conventional vegetation base material, it was shown that the vegetation of the plant is also excellent.
