The vegetation rod is settled in the pit formed by digging the slope, and serves as a barrier to prevent the soil on the slope from being lost by rainwater. As time elapses, vegetative colonization proceeds from the vegetation rod, forming a vegetative zone. It is possible to permanently prevent erosion of soil on the slope by the Early Age.

Description

Vegetation rod and method of forming a vegetation rod for preventing soil erosion using the same {METHOD FOR MAKING VEGETATIVE FILTER STRIP}

The present invention relates to a technique for preventing soil runoff or surface erosion, and more particularly, to a method of forming the Cenozoic for preventing soil runoff and surface erosion by using a plant community.

Soil is eroded and lost by natural phenomena such as wind or precipitation, or by man-made activities such as tillage and civil works. Loss of topsoil due to soil erosion has a problem in that various functions of soil such as plant production, pollution purification, greenhouse gas storage, and flood control are lost.

Since 76% of the country is composed of mountainous areas with a slope of 2% or higher, Korea is very vulnerable to soil erosion due to concentrated rainfall in summer. The annual soil loss per unit area in Korea is estimated to be 41.0 MT/ha/yr for fields, 11.1 MT/ha/yr for orchards, and 3.5 MT/ha/yr for forests. In particular, the soil loss in the highland fields distributed in Gangwon-do is very high at 50-80 MT/ha/yr. The soil erosion risk of Korea (>11 MT/ha/yr) is 22.3%, which is very high compared to 9.8% in the US and 7% in Canada. Considering that it takes more than 200 years to produce 1 cm of soil, soil loss due to rainwater is very serious.

In order to prevent soil erosion and loss, various methods are being used, such as mulching, vegetation cover, contour cultivation, stairs installation, windbreak forest formation, rainwater infiltration zone formation, sedimentation pond and reservoir installation, and vegetation and gravel drainage channel installation. In particular, the soil erosion and loss reduction method using the Early Proterozoic has proven its effectiveness through previous studies and is widely used in the field. The Cenozoic is a plant community planted perpendicular to the slope. It reduces the speed of runoff along the slope to reduce topsoil erosion and reduces the movement of soil moving downstream along the runoff. Depending on the slope of the site, the width and spacing of the Czozoic era are determined and utilized. The size and location of the Czorozoic are determined by rainfall, topography, and Saturn.

For the successful field application of the Early Cenozoic, the survival and maintenance of vegetation is most important. This is because, in the area to which the Early Proterozoic is to be applied, vegetation survival and growth are very unfavorable due to the erosion and loss of topsoil. Topsoil has higher organic matter content, clay content, nutrient content, and moisturizing power than subsoil, which is advantageous for vegetation growth. On the other hand, subsoil is subject to less weathering than topsoil, so it has many coarse particles such as quartz and feldspar, low nutrients and organic matter content, and low adhesion between particles, so it is easily lost by rainfall and difficult to adhere to food.

Therefore, when the subsoil is exposed to the surface due to soil erosion and attempts to form the Early Proterozoic are made, the failure occurs frequently due to poor vegetation establishment and growth. It is necessary to develop and apply a method for forming the Early Cretaceous period that can be successfully and easily applied to the field in the soil where the subsoil is exposed and the diet and growth are unfavorable.

The present invention is to solve the above problems, and to provide a vegetation rod and a method for forming a Czozoic using the same, which facilitates vegetative adhesion even under adverse conditions such as exposing the subsoil, so that the Czorozoic can be successfully formed. The purpose is to have.

On the other hand, other objects not specified in the present invention will be further considered within the range that can be easily inferred from the following detailed description and effects thereof.

Vegetation rod according to the present invention for achieving the above object, the cylindrical net is arranged long in one direction, the receiving part is provided therein; Functional soil contained in the receiving portion of the net, including soil and plant seeds; and a fixing member for fixing and fixing the cylindrical net to the ground.

In one embodiment of the present invention, the net is formed by rolling natural fibers, and in particular, it is preferable that the net is a core net made of coconut fibers.

In one embodiment of the present invention, the cylindrical net is fixed in a pit formed in a direction crossing the inclined direction of the ground, and it is preferable to install it in a plurality of rows.

In an example of the present invention, the functional soil is 70 to 90% by weight of soil and compost, and the main material mixed in a ratio of 10 to 30% by weight, and limestone powder mixed in a ratio of 3 to 7% by weight with respect to the main material, 2 to 4 kg per 1 ton of the main material is mixed, and a fertilizer containing nitrogen, phosphorus, and potassium, and 0.6 to 1 kg of plant seeds are mixed per 1 ton of the main material.

On the other hand, the Czozoic composition method according to the present invention for achieving the above object, (a) forming a long pit along the direction intersecting the inclined direction of the ground; (b) disposing a cylindrical vegetation rod, and fixing the vegetation rod to the ground with the fixing member; characterized in that it includes. The fixing member is a fixing pin formed with a sharp lower end, and the fixing pin is inserted and installed in the ground through the vegetation rod.

On the other hand, the Czorozoic composition method according to another example of the present invention for achieving the above object, (a) forming a long pit along the direction intersecting the inclined direction of the ground; (b) disposing the net so that both ends of the net woven with natural fibers span the ground and the central part is inserted into the pit; (c) placing functional soil containing soil and plant seeds in the part laid on the pit in the net, and sealing both ends of the net to form a cylindrical vegetation rod; and (d) inserting a fixing pin through the vegetation rod into the ground to fix the vegetation rod.

In an example of the present invention, the pit is formed in an arc shape and the depth is preferably in the range of 40 to 60% of the diameter of the vegetation rod.

When the vegetation rod according to the present invention is used, plant seeds can germinate very easily even in an area in which subsoil is exposed and placed in a condition in which it is difficult to adhere to vegetation to form a vegetation zone.

In addition, there is an advantage that the vegetation rod itself plays a role in preventing the loss of soil and soil due to rain in the process of vegetative colonization.

The net of the vegetation rod is made of coconut fiber, so it is not only eco-friendly, but also has the advantage of supporting the vegetation with organic nutrients after corrosion.

※ It is revealed that the accompanying drawings are exemplified as a reference for understanding the technical idea of the present invention, and the scope of the present invention is not limited thereby.

In the description of the present invention, if it is determined that the subject matter of the present invention may be unnecessarily obscured as it is obvious to those skilled in the art with respect to related known functions, the detailed description will be omitted.

The present invention relates to a method of forming a 'Cerrozoic' for preventing surface erosion and soil runoff caused by rainfall, and more particularly to a vegetation rod designed to be used in the composition of the Cerrozoic.

Hereinafter, with reference to the accompanying drawings, a vegetation rod according to an embodiment of the present invention, and a method for forming a vegetation rod using the vegetation rod will be described in more detail.

1 is a schematic perspective view of a vegetation rod according to an example of the present invention.

Referring to FIG. 1 , the vegetation rod 100 according to an embodiment of the present invention includes a net 10 , a functional soil 20 and a fixing pin 30 .

The net 10 is formed in a substantially cylindrical shape. Cylindrical does not mean a perfect circle, but is used in a broad sense including shapes formed in closed curves such as ovals. When both ends of the net 10 are rolled to form a cylindrical shape, a receiving portion is formed therein. The receiving part contains functional soil 20 to be described later. The net 10 is formed in a range of several tens of cm in diameter and several m in length.

In this embodiment, the net 10 is made of natural fibers, and in particular, a net woven from coconut fibers as shown in FIG. 2 is used. You can use coconut fiber woven nets because they are ready-made. However, if the coconut fibers are woven too loosely, the functional soil contained therein may be lost, so a tightly woven net can be used or a sparse net can be used by overlapping several layers. As shown in FIG. 2, since the coarse fibers of the coconet fibers come out, the voids between the weft and warp fibers are also closed by the coconut fibers. However, even if the net is too dense, it should be formed so that plant seeds can germinate and sprout.

As shown in FIG. 2 , since the surface of the coconut fibers is very rough due to the fine fibers, it is easily entangled with the soil and settled on the ground. Above all, since coconut fiber is a natural fiber, it is not only eco-friendly, but also has the advantage of preventing the loss of soil and soil in the process of plant growth and corroding after planting, and functions as compost.

Functional soil 20 is contained inside the cylindrical net (10). Functional soil provides a basis for plant seeds to thrive. To this end, the functional soil in this example includes limestone powder, fertilizer and plant seeds in the main material mixed in a ratio of 70 to 90% by weight of soil and 10 to 30% by weight of compost. Limestone powder is mixed in a ratio of 3 to 7 wt% with respect to the main material. That is, 3 to 7 g is blended with respect to 100 g of the main material. Fertilizer is mixed with 2~4kg per ton of main material including nitrogen, phosphorus and potassium. Plant seeds are mixed in 0.6~1kg per 1ton of main material.

Soil should have physical properties suitable for vegetation establishment and growth, i.e., moisture retention, drainage, and breathability. For this purpose, sandy loam consisting of 45 - 70% sand, 10 - 50% silt and 10 - 20% clay is used.

Use mature compost for compost. Compost aggregates soil particles and increases moisture retention and breathability. In addition, it supplies nutrients (N, P, S, Mo, B, etc.) of vegetation and improves fertility by increasing the cation exchange capacity of the soil.

Fertilizer uses a compound fertilizer containing N, P, and K.

Limestone powder supplies Ca, an essential nutrient for vegetation. It is also used for the purpose of preventing soil acidification, which may be caused by a large amount of compost. In this example, limestone powder is mixed with 5% (weight ratio) of fine-grained limestone having a particle size of 10 mm or less in the main material.

Seeds are mixed with artificial soil at a rate of 600g - 1kg/ton. Mostly perennial herbs are used. In particular, it has a strong stem, so it slows down the runoff and filters soil and soil to prevent loss. For example, turfgrass may be suitable for soil erosion and loss prevention.

The installation process of the vegetation rod 100 will be described with reference to FIGS. 3 and 4 .

3 is a schematic cross-sectional view of a state in which the vegetation rod is installed on the inclined surface, and FIG. 4 is a view for explaining the arrangement interval of the vegetation rod.

3 and 4, the vegetation rod 100 is installed on the inclined surface (s), first in the direction intersecting the inclined direction (arrow) of the inclined surface (s), preferably in the vertical direction pit (h) form a long The pits (h) are formed in a plurality of rows spaced apart along the inclined direction.

After the vegetation rod 100 is seated in the pit (h), the vegetation rod 100 is fixed by inserting a fixing member, for example, a fixing pin 30 through the vegetation rod 100 into the ground (g). In addition to the fixing pin 30, other fixing members may be used.

As shown in Figure 4, the spacing between the vegetation rods 100, it is preferable to maintain the diameter (d) degree of the vegetation rods (100). Similarly, the height at which the vegetation rod 100 protrudes upward of the pit (h) is also formed about the diameter of the vegetation rod 100 . In other words, the depth of the pit (h) is formed about the radius (d/2) of the vegetation rod (100).

Up to now, it is a case of installing the pre-manufactured vegetation rod 100 on the ground. Hereinafter, with reference to FIG. 5, the case of directly manufacturing and using the vegetation rod in the field will be described.

5 is a schematic flowchart of a method of forming a vegetation rod by manufacturing a vegetation rod in the field. Referring to Figure 5, first dig a pit (h) to a depth of about half the diameter (d) of the vegetation rod (100) on the slope. In order to form a vegetation zone, the pits (h) are arranged in a plurality of rows with an interval about the diameter of the vegetation rod.

After that, the coconut net is overlapped with 2 to 5 layers and placed on the pit (h). At this time, both ends of the net are placed on the outside of the pit (h). In the case of using a pre-finished vegetation rod, the extent of the net is important because it is necessary to prevent the internal functional soil from leaking out during the movement process. However, if the vegetation rod is directly manufactured on the spot, the risk of leakage of functional soil is relatively low, so a slightly more relaxed standard can be applied in the selection of the net.

The functional soil 20 is placed on the net 10 in a certain volume and both ends of the net 10 are mutually bound to complete the vegetation rod 100 in the pit (h). If necessary, the vegetation rod 100 is firmly fixed to the ground using the fixing pin 30 . Afterwards, irrigate so that the moisture content is 30 - 40% by volume.

As described above, by forming a plurality of vegetation rods in a certain area, a vegetative zone can be formed. The length of the Cenozoic is determined by the surface characteristics of the site, and several vegetation bars are connected in series and used. The Cenozoic is placed side by side with the contour line (orthogonal to the runoff flow direction). The larger the slope of the site, the narrower the spacing and the wider the width. For example, as shown in the table shown in FIG. 6 , the width and spacing of the Cenozoic era may be determined according to the inclination of the ground.

As described above, when the vegetation rod according to the present invention is used, plant seeds germinate very easily even in an area in which the subsoil is exposed and it is difficult to adhere to the vegetation to form the vegetation zone. In addition, there is an advantage that the vegetation rod itself plays a role in preventing the loss of soil and soil due to rain in the process of vegetative colonization.

The net of the vegetation rod is made of coconut fiber, so it is not only eco-friendly, but also has the advantage of supporting the vegetation with organic nutrients after corrosion.

Reference number 50, which is not described, is a plant germinated from a vegetation rod later.

The protection scope of the present invention is not limited to the description and expression of the embodiments explicitly described above. In addition, it is added once again that the protection scope of the present invention cannot be limited due to obvious changes or substitutions in the technical field to which the present invention pertains.
