Description

[Technical field]

[0001] The present invention relates to a vegetation sandbag that contains functional ingredients for growing plants in a desired state. [Background technology]

[0002] Sandbags are widely used in the civil engineering field for power line sites, river banks, road slopes, medians, airport landing strips, etc. Sandbags containing cultivation materials such as soil, and functional ingredients such as fertilizers and plant seeds are also known, and are widely used as vegetation sandbags for the construction of greening surfaces (for example, Patent Document 1).

[0003] In sandbags that contain functional ingredients such as fertilizer in addition to cultivation materials such as soil, if the functional ingredients dissolve and diffuse from the sandbag, the sandbag will not function as intended and the desired plant growth conditions will not be achieved.

[0004] In recent years, a technology has been developed to effectively utilize coal ash, which is a waste material, by producing granulated material from coal ash as a civil engineering material. Although it is possible to use granulated material derived from coal ash as the material to be stored in sandbags, there is a concern that coal ash components that have an adverse effect on the environment may leach out.

[0005] Given this situation, there is a demand for technology that can prevent the functional ingredients in sandbags from leaching out. [Prior art documents] [Patent documents]

[Diagram 2] 1 is a schematic conceptual diagram of a vegetative sandbag according to one embodiment of the present invention. [Diagram 3] 1 is a schematic conceptual diagram of a vegetative sandbag according to another embodiment of the present invention.

[Diagram 5] FIG. 1 is an explanatory diagram of an example of use of a vegetation sandbag according to one embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Fig. 1 shows the appearance of a vegetation sandbag according to one embodiment of the present invention, with Fig. 1(a) showing the state in which the sandbag is being filled with contents, and Fig. 1(b) showing the state in which the sandbag has been filled with the contents as desired. Fig. 2 shows a schematic cross-sectional view of the vegetation sandbag according to one embodiment of the present invention, and Fig. 3 shows a schematic cross-sectional view of the vegetation sandbag according to another embodiment of the present invention.

[0025] As shown in Fig. 1(a), a sandbag 1 of a given size (e.g., 40 cm x 60 cm) contains cultivation materials 2 such as soil (vegetation soil) and gravel, and a functional agent, a weed-suppressing agent 3 containing a metal element that has a weed-suppressing effect of inhibiting and suppressing plant growth. The ratio of the cultivation materials 2 to the inhibitor 3 is adjusted to, for example, 7:3.

[0026] For example, coal ash or slag is used as the retarder 3, and the metal elements having the weed-suppressing effect are derived from coal ash or slag. As shown in Fig. 1(b), a vegetation sandbag 5 is formed by storing cultivation materials 2 and a retarder 3 in a sandbag 1 and closing the opening.

[0027] The vegetation sandbag 5 contains a metal element having a weed-suppressing effect that inhibits and regulates the growth of plants. Therefore, the growth of plants is inhibited and regulated by the metal element having a weed-suppressing effect. In other words, the growth state of the plant is controlled by regulating the size and color of the leaves, roots, stems, flowering time, etc., which are the morphology of the plant, and the desired size, color, etc. are maintained.

[0028] Therefore, it is possible to adjust the plant's form (size, color, flowering time, etc.) and maintain (control) the plant's form. In other words, by spreading the vegetation sandbags 5 in the required area in the required place, it is possible to maintain and control the color, size, texture, etc. of the plant (leaves) in the desired area according to the location.

[0029] As functional agents, for example, growth aids, herbicides, plant seeds, soil conditioners (water retention regulators, pH adjusters, etc.) can be applied.

[0030] The sandbag 1 used in the vegetation sandbag 5 has an outflow prevention means for preventing the outflow of metal elements contained in the inhibitor 3 (functional agent). The outflow prevention means provided in the sandbag 1 can prevent (prevent) the outflow of metal elements. This makes it possible to prevent the internal metal elements (functional components) from eluting.

[0031] 2, as an outflow prevention means, an adsorbent 8 serving as an adsorption means for adsorbing metal elements is provided on the inner surface of the sandbag 1. The adsorbent 8 is composed of an adsorption means such as porous zirconium sulfate, glucomannan, etc.

[0032] In addition, it is also possible to provide a means for preventing outflow by directly applying an adsorption means such as porous zirconium sulfate or glucomannan to the inner surface of the sandbag 1.

[0033] By providing the adsorbent 8 on the inner surface of the sandbag 1, the metal element M near the inner peripheral surface of the sandbag 1 is adsorbed by the adsorbent 8. This prevents the metal element M from eluting or diffusing outside the sandbag 1, and makes it possible to set the effective range of the function of maintaining (controlling) the morphology of the plant to just the range in which the vegetation sandbag 5 is installed. This makes it possible to prevent excessive diffusion of the functional component while ensuring safety by using a simple sandbag 1.

[0034] As shown in Fig. 3, the sandbag 1A itself is made of an absorbent fiber as a means for preventing outflow. As the absorbent fiber, a chelating fiber (N-glucamine type resin) or the like can be used.

[0035] By making the sandbag 1A itself out of absorbent fiber, the metal element M near the inner periphery of the sandbag 1A is absorbed by the fiber of the sandbag itself. This prevents the metal element M from eluting or diffusing outside the sandbag 1A, and makes it possible to set the effective range of the function of maintaining (controlling) the morphology of the plant only within the area where the vegetation sandbag 5 is installed. This makes it possible to prevent excessive diffusion of the functional component while ensuring safety using a simple sandbag 1.

[0036] The metal element includes at least one of boron (B), aluminum (Al), copper (Cu), molybdenum (Mo), iron (Fe), lithium (Li), cobalt (Co), and zinc (Zn). The at least one metal element is preferably any one of boron (B), aluminum (Al), copper (Cu), molybdenum (Mo), and cobalt (Co).

[0037] By using the above metal elements, it is possible to regulate plant growth within a specified concentration range while satisfying environmental standards.

[0038] Within the same site, vegetation sandbags 5 (see Figure 1) with different types of inhibitors 3 (see Figure 1) can be installed depending on the location, such as when growing plants for the purpose of protecting buildings and structures, or when growing plants for the purpose of prioritizing appearance.

[0039] This allows the creation of any desired green space and landscape from a range of options, simply by preparing and setting up any desired vegetation sandbag 5 (see Figure 1), depending on the characteristics of the area in which the necessary buildings and structures are located. Moreover, the design can be easily changed by replacing the vegetation sandbag 5 (see Figure 1).

[0040] When the above-mentioned metal elements are used, the plant morphology can be controlled in any desired manner depending on the type and combination of metal elements in the inhibitor 3 (see Figure 1) contained in the sandbag 1 (see Figure 1).

[0041] For example, the leaf area can be reduced while the weight is not significantly reduced to maintain the texture, or the leaf area can be reduced but the weight is reduced to make the texture lighter, or the leaf area and weight can be reduced to give the plant a lighter appearance and texture overall.

[0042] FIG. 4 shows an explanation of the effect when boron (B) is used as the metal element of the plant morphology control agent (Inhibitor 3).

[0043] Figure 4(a) is a graph showing the relationship between the boron (B) concentration (mg / l) and the amount of chlorophyll, which is an indication of the degree of greening. Figure 4(b) is a graph showing the relationship between the boron (B) concentration (mg / l) and leaf weight. Figure 4(c) is a graph showing the daily change in germination rate at a standard concentration (e.g., 10 mg / l).

[0044] As shown in Figure 4(a), when boron (B) was used, the degree of greenness decreased as the concentration increased from 1 (mg / l), 5 (mg / l), 10 (mg / l), 50 (mg / l), and 100 (mg / l), and as shown in Figure 4(b), the weight became lighter as the concentration increased. As shown in Figure 4(c), for example, at a concentration of 10 (mg / l), germination continued for about four days, and stopped after the fourth day.

[0045] When boron (B) is used as the metal element in inhibitor 3 (see Figure 1), as the concentration increases, the degree of greenness decreases and the leaf size changes very little, but the weight becomes lighter (the texture decreases).

[0046] When aluminum (Al) is used as the metal element of inhibitor 3 (see Figure 1), it has been confirmed that even when the concentration is increased, the degree of greenness does not change significantly, and the size of the leaves remains almost unchanged, but the weight becomes lighter (the texture becomes less).

[0047] When copper (Cu) is used as the metal element in inhibitor 3 (see Figure 1), it has been confirmed that as the concentration increases, the degree of greenness decreases, the leaf size becomes significantly smaller, and the weight becomes lighter (reduced texture).

[0048] When molybdenum (Mo) was used as the metal element in Inhibitor 3 (see Figure 1), it was confirmed that as the concentration increased, the degree of greenness decreased significantly, the leaf size became significantly smaller, and the weight became significantly lighter (the texture was significantly reduced).

[0049] When iron (Fe) is used as the metal element in inhibitor 3 (see Figure 1), it has been confirmed that as the concentration increases, the degree of greenness decreases and the leaf size changes very little, but the weight becomes lighter (the texture decreases).

[0050] When lithium (Li) was used as the metal element in inhibitor 3 (see Figure 1), it was confirmed that as the concentration increased, the degree of greenness decreased significantly, the leaf size became significantly smaller, and the weight became significantly lighter (the texture was significantly reduced).

[0051] When cobalt (Co) was used as the metal element in inhibitor 3 (see Figure 1), it was confirmed that as the concentration increased, the degree of greenness was significantly reduced, the leaf size was significantly reduced, and the weight was significantly lighter (the texture was significantly reduced).

[0052] When zinc (Zn) is used as the metal element in inhibitor 3 (see Figure 1), it has been confirmed that as the concentration increases, the degree of greenness decreases, the size of the leaves decreases, and the weight becomes lighter (reduced texture).

[0053] As described above, by using any one of boron (B), aluminum (Al), copper (Cu), molybdenum (Mo), iron (Fe), lithium (Li), cobalt (Co), zinc (Zn), or an appropriate combination of these as the metal element of the inhibitor 3 (see Figure 1) contained in the sandbag 1, it is possible to regulate plant growth within a specified concentration range while satisfying environmental standards.

[0054] An application example of the vegetation sandbag 5 will be described with reference to FIG.

[0055] FIG. 5 shows the use of a vegetation sandbag 5 according to one embodiment of the present invention in a fallow field.

[0056] As shown in the figure, vegetation sandbags 5 are laid in a fallow field 15 in an area of ​​a desired pattern or design, dividing the area into soil and vegetation sandbag 5 areas. Tall plants grow in the soil areas, and plants 6 are grown to a specified level only in the areas of vegetation sandbag 5. Since vegetation sandbag 5 prevents the diffusion of metal elements, which are functional members that maintain the shape of plants 6, the area in which plants 6 are grown to a desired state is limited to the area in which vegetation sandbag 5 is installed.

[0057] Therefore, in comparison with the tall plants in the soil portion of the fallow field 15, the desired pattern or picture can be accurately expressed by the short plants 6 whose shapes are maintained.

[0058] This makes it possible to create a pattern or picture using plants 6 in the fallow field 15 while maintaining the desired pattern or picture as intended.

[0059] It is also possible to lay vegetation sandbags containing a functional agent that actively promotes the growth of plants 6 in a desired pattern or design range in the fallow field 15. This makes it possible to actively grow plants 6 in a desired pattern or design range.

[0060] It is also possible to lay vegetation sandbags using pesticides such as herbicides as functional agents in areas other than the desired pattern or picture in the fallow field 15. This makes it possible to clearly separate the desired pattern or picture from the area where no other plants grow, and to highlight the desired pattern or picture expressed by the plants 6.

[0061] In addition to the above-mentioned embodiment, the vegetation sandbag of the present invention can be applied to any place where it is desired to set the effective range of the function of maintaining (controlling) the morphology of plants to a desired range. For example, the vegetation sandbag can be laid on land where it is difficult to mow grass or where it is difficult for people to enter, and where it is necessary to suppress the runoff of functional agents. When restoring the land to its original state, it is only necessary to remove the vegetation sandbag without replacing the soil. [Industrial Applicability]

[0062] The present invention can be used in the vegetation sandbag industry. [Explanation of symbols]
