Description

The present invention relates to a vegetation sandbag that contains functional ingredients for growing plants in a desired state.

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

In sandbags that contain functional ingredients such as fertilizer in addition to soil and other cultivation materials, if the functional ingredients leach out of the sandbag and spread, the sandbag will not function as intended and the desired plant growth conditions will not be achieved.

In recent years, a technology has been developed that uses coal ash to produce granulated materials for use in civil engineering projects, making effective use of coal ash, which is a waste material. It is possible to use granulated materials derived from coal ash as the material to be stored in sandbags, but there are concerns that components of the coal ash that have an adverse effect on the environment may leach out.

In light of this situation, there is a demand for technology that can prevent the functional ingredients in sandbags from leaching out.

Japanese Patent Application Publication No. 5-148840

The present invention was made in consideration of the above situation, and aims to provide a vegetation sandbag that prevents the functional ingredients inside from leaching out.

In particular, the objective is to provide a vegetation sandbag in which a weed-suppressing component containing a metal element that controls (suppresses) plant growth as a functional component is contained in the sandbag together with cultivation materials, and in which the weed-suppressing component does not diffuse.

The vegetation sandbag of the present invention comprises a functional agent that regulates plant growth and a sandbag containing the functional agent, the sandbag having an outflow prevention means for preventing the outflow of the functional agent, the functional agent being an inhibitor containing a metal element that has a weed-suppressing effect that inhibits plant growth and suppresses plant growth, and the outflow prevention means is preferably an adsorption means provided on the inner surface of the sandbag and made of porous zirconium sulfate or glucomannan that adsorbs the inhibitor.

In this way, the leakage prevention means provided in the sandbag can suppress (prevent) the leakage of the functional agent, thereby making it possible to prevent the functional ingredient inside from leaching out.
The functional agent can be adsorbed by an adsorption means provided on the inner surface of the sandbag, thereby suppressing (preventing) the leakage of the functional agent. As the adsorption means, porous zirconium sulfate, glucomannan, etc. can be used.
In addition, it is possible to suppress (prevent) the outflow of metal elements that have a weed-suppressing effect, and to reliably adjust the morphology (size, color, flowering period, etc.) of the plants in the area where the sandbags are installed, making it possible to maintain (control) the morphology of the plants in a desired state.

In order to achieve the above-mentioned object, the vegetation sandbag of the present invention according to claim 1 comprises a sandbag containing a functional agent, the sandbag having an outflow prevention means for preventing the outflow of the functional agent, the functional agent being an inhibitor containing a metal element having a weed-suppressing effect of inhibiting the growth of plants and suppressing their growth, and the outflow prevention means is characterized in that the sandbag is formed from an adsorbent fiber made of a chelating fiber.

In the present invention according to claim 1 , the leakage prevention means provided in the sandbag can suppress (prevent) leakage of the functional agent, which makes it possible to prevent the functional ingredient inside from leaching out.
The functional agent is adsorbed to the fibers forming the sandbag, thereby suppressing (preventing) the leakage of the functional agent. Chelate fibers (N-glucamine type resin) and the like can be used as the adsorbent fibers.
In addition, it is possible to suppress (prevent) the outflow of metal elements that have a weed-suppressing effect, and to reliably adjust the morphology (size, color, flowering period, etc.) of the plants in the area where the sandbags are installed, making it possible to maintain (control) the morphology of the plants in a desired state.

In addition, the vegetation sandbag of the present invention according to claim 2 is characterized in that, in the vegetation sandbag described in claim 1 , 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).

Moreover, the at least one metal element is preferably any one of boron (B), aluminum (Al), copper (Cu), molybdenum (Mo), and cobalt (Co).

1 is an external view of a vegetation sandbag according to an embodiment of the present invention. 1 is a schematic conceptual diagram of a vegetative sandbag according to one embodiment of the present invention. 1 is a schematic conceptual diagram of a vegetative sandbag according to another embodiment of the present invention. FIG. 1 is an explanatory diagram of the effect when boron (B) is used as a functional agent. FIG. 1 is an explanatory diagram of an example of use of a vegetation sandbag according to one embodiment of the present invention.

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

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, an inhibitor 3, which contains 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, a ratio of 7:3.

For example, coal ash or slag is used as the inhibitor 3, and the metal elements that have the weed-suppressing effect are derived from coal ash or slag. As shown in FIG. 1(b), the cultivation material 2 and the inhibitor 3 are placed in a sandbag 1, and the opening is closed to form a vegetation sandbag 5.

The vegetation sandbag 5 contains metal elements with a weed-suppressing effect that inhibits and regulates the growth of plants. Therefore, the metal elements with weed-suppressing effect inhibit the growth of plants and regulate their growth. In other words, the growth state 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.

This makes it possible to adjust the plant's morphology (size, color, flowering period, etc.) and maintain (control) the plant's morphology. In other words, by spreading the vegetation sandbags 5 over the required area in the required location, it is possible to maintain and control the color, size, texture, etc. of the plant (leaves) in a desired area according to the location.

Examples of functional agents that can be applied include growth aids, herbicides, plant seeds, and soil conditioners (water retention regulators, pH adjusters, etc.).

The sandbag 1 used in the vegetation sandbag 5 has an outflow prevention means that prevents 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 leaching out.

As shown in FIG. 2, the sandbag 1 is provided with an adsorbent 8 on its inner surface as a means for preventing leakage, which acts as an adsorption means for adsorbing metal elements. The adsorbent 8 is made of an adsorption means such as porous zirconium sulfate or glucomannan.

It is also possible to provide a means for preventing leakage by directly applying an adsorption means such as porous zirconium sulfate or glucomannan to the inner surface of the sandbag 1.

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 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.

As shown in Figure 3, the sandbag 1A itself is made of absorbent fiber as a means for preventing leakage. Chelate fiber (N-glucamine type resin) or the like can be used as the absorbent fiber.

By making the sandbag 1A itself out of absorbent fiber, the metal element M near the inner surface 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 shape 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.

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 of boron (B), aluminum (Al), copper (Cu), molybdenum (Mo), and cobalt (Co).

By using the above metal elements, plant growth can be regulated within a specified concentration range while meeting environmental standards.

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

As a result, by preparing and setting up any desired vegetation sandbag 5 (see Figure 1), it is possible to easily create any desired green space and green space with any desired landscape from a number of different options depending on the characteristics of the area in which the necessary buildings and structures are located. Moreover, it can be easily changed by replacing the vegetation sandbag 5 (see Figure 1).

When using the above-mentioned metal elements, 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).

For example, it is possible to adjust the leaf area to a state where the leaf weight is not significantly reduced but the texture is maintained, or the leaf area is not significantly 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.

Figure 4 shows an explanation of the effect of using boron (B) as the metal element of the plant morphology control agent (Inhibitor 3).

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

As shown in Figure 4(a), when boron (B) is used, the degree of greenness decreases as the concentration increases from 1 (mg/l), 5 (mg/l), 10 (mg/l), 50 (mg/l), to 100 (mg/l), and as shown in Figure 4(b), the weight decreases as the concentration increases. As shown in Figure 4(c), for example, at a concentration of 10 (mg/l), germination continues for approximately four days, and germination stops after the fourth day.

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 while there is almost no change in leaf size, the weight becomes lighter (the texture becomes less).

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

When copper (Cu) is used as the metal element of 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 (the texture becomes less).

When molybdenum (Mo) is used as the metal element of inhibitor 3 (see Figure 1), it has been confirmed that as the concentration increases, the degree of greenness decreases significantly, the leaf size decreases significantly, and the weight also becomes significantly lighter (the texture is significantly reduced).

When iron (Fe) is used as the metal element of 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 becomes less).

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

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

When zinc (Zn) is used as the metal element of 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 (the texture decreases).

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

An example of application of the vegetation sandbag 5 is explained based on Figure 5.

Figure 5 shows the use of vegetation sandbags 5 according to one embodiment of the present invention in a fallow field.

As shown in the figure, vegetation sandbags 5 are laid in a desired pattern or design area of a fallow field 15, 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 vegetation sandbag 5 areas. The vegetation sandbag 5 prevents the diffusion of metal elements, which are functional components that maintain the shape of the plants 6, so the area in which the plants 6 are grown to the desired state is limited to the area where the vegetation sandbags 5 are installed.

As a result, it becomes possible to accurately express the desired patterns and pictures using short plants 6 that maintain their shape in comparison with the tall plants in the soil of the fallow field 15.

This makes it possible to create patterns or pictures using plants 6 in fallow fields 15 while maintaining the desired pattern or picture shape as intended.

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

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

In addition to the above-mentioned embodiments, the vegetation sandbags of the present invention can be used in places 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, vegetation sandbags 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 prevent the runoff of functional agents. When restoring the land to its original state, it is sufficient to simply remove the vegetation sandbags without replacing the soil.

This invention can be used in the vegetation sandbag industry.
