Description

Technical Field

[0001] The present invention relates to a solidified weed control material containing a suppressing component for regulating (suppressing) the growth of plants. to the object

Background Art

[0002] In areas such as transmission line sites, river embankments, road slopes, median strips, and airport landing strips, plants may be planted for greening in order to prevent erosion, ensure safety, ensure the landscape, prevent foundation erosion, prevent flying sand, etc. If the plants for greening grow too much, they may have adverse effects in terms of crime prevention, appearance, and function, so regular maintenance such as mowing is required. However, since such greening locations are difficult for people to access, the current situation is that maintenance requires a great deal of labor, time, and cost.

[0003] For this reason, conventionally, instead of regular mowing work, herbicides and the like are used to wither the plants so that the plants do not grow, eliminating the adverse effects caused by excessive growth of the plants (for example, Patent Document 1). The technique shown in Patent Document 1 is a technique of mixing an agent that suppresses growth into a herbicide to reduce the burden of weeding.

[0004] In areas where greening is carried out, it is important in terms of the environmental image and the like that the plants continue to exist even if the amount of plants decreases. However, when the technique of Patent Document 1 is used, since it is a weeding technique, after weeding, the greening area will be in a state where no plants are growing. If weeding is carried out in the greening area and the plants are eliminated, the landscape including the impression on appearance and safety will be damaged, and the current situation is that it is not a good idea to carry out weeding in the greening area.

Modes for Carrying Out the Invention

[0031] The solidified weed control material of the present invention is a solidified material for maintaining the growth of plants in a predetermined state, and a suppressing member containing component elements having a weed control effect of inhibiting the growth of plants and suppressing growth elutes in a desired state, and the elution of the suppressing member can be controlled while maintaining a predetermined shape.

[0032] FIG. 1 schematically shows the situation of the process for manufacturing the solidified weed control material according to an embodiment of the present invention, FIG. 2 shows the explanation of the basic specifications of the components of the solidified weed control material, and FIG. 3 shows a flowchart for explaining the manufacturing process of the solidified weed control material according to an embodiment of the present invention.

[0033] As shown in Fig. 1, coal ash (fly ash: FA, clinker ash is also acceptable) 1 containing the metal of the suppression member as the main material, paper sludge ash (PSA) 2 as a solidification accelerator (solidification member) as a secondary material, blast furnace slag powder (SL) 3 as a solidifying agent (solidification member) as a secondary material, and unfired shell powder (SP) 4 (shell powder) as a solidifying agent (solidification member) as a secondary material are put into the container 10.

[0034] An appropriate amount of water as needed and the mixing ratio of the main material and the secondary material are set as appropriate, and a weed control material solidified product 8 of a solidified body 5 or solid particles 6 of a pulverized stone body is produced.

[0035] Therefore, as the main material, it becomes possible to effectively utilize coal ash 1 that becomes waste as a suppression member. And as the solidification member (solidifying agent, solidification accelerator), it becomes possible to effectively utilize paper sludge ash 2 and (or) blast furnace slag powder 3 that become waste. In addition, it becomes possible to effectively utilize unfired shell powder 4 that has become waste and left many problems in treatment as a solidifying agent, and to obtain a weed control material solidified product 8 (solidified body 5, solid particles 6) having a desired strength.

[0036] As shown in Fig. 2, the role of coal ash 1 is to supply mainly aluminum (Al), sodium (Na), boron (B), and lithium (Li) as weed control components. As weed control components, in addition to the above, copper (Cu), molybdenum (Mo), iron (Fe), cobalt (Co), and zinc (Zn) are applied. The mixing ratio of coal ash 1 is 30% to 70%, preferably 40% to 60%.

[0037] The role of paper sludge ash 2 is to promote solidification (solidification accelerator) and supply sodium (Na) and lithium (Li) as weed control components. The mixing ratio of paper sludge ash 2 is 20% to 40%.

[0038] The role of blast furnace slag powder 3 is to promote solidification and increase strength (solidifying agent) and suppress the elution of weed control components. The mixing ratio of blast furnace slag powder 3 is 10% to 25% by volume ratio.

[0039] The role of the uncalcined shell powder 4 is to achieve solidification and porosity (as a solidifying agent) and suppress the elution of the weed-suppressing component. The mixing ratio of the uncalcined shell powder 4 is set to be 10% to 25% by volume ratio.

[0040] Water is set to be 40% to 70% with respect to the powder (weed-suppressing component, solidification accelerator, solidified body). That is, the (water / powder) ratio is set to be 40% to 70%. And the content of the solidification accelerator is 40% to 20%, and the content of the solidifying agent is 50% to 20%.

[0041] Specific manufacturing method: As shown in Figure 3, in step S1, the coal ash 1 and the auxiliary materials are mixed at a predetermined ratio. In step S2, water is added and mixed for a predetermined time. In step S3, the mixture is filled into a mold (container 10), and in step S4, it is cured in the air (cured in the air while preventing drying). Finally, in step S5, it is left standing at room temperature for a predetermined time to obtain the weed-suppressing material solidified product 8.

[0042] The weed-suppressing material solidified product 8 (solidified body 5, solid particles 6) is such that the suppressing member is solidified by the solidifying member (solidifying agent, solidification accelerator), and the weed-suppressing member is solidified so as to be eluted in a desired state. By eluting the weed-suppressing member in a desired state, the form of the plant (size, color, flowering time, etc.) is adjusted, and the weed-suppressing material solidified product 8 that can maintain (control) the form of the plant is obtained. By appropriately adjusting the mixing ratio of the suppressing member and the solidifying member (solidifying agent, solidification accelerator), the hardness and the elution state of the suppressing member can be adjusted.

[0043] The component elements of the suppressing member preferably include at least one of boron (B), aluminum (Al), copper (Cu), molybdenum (Mo), iron (Fe), lithium (Li), cobalt (Co), zinc (Zn), and sodium (Na). For this reason, within a predetermined concentration range, the growth of plants can be adjusted while meeting environmental standards.

[0044] Based on FIG. 4, an example of the use of the weed control material solidified product 8 (solidified body 5, solid particles 6) will be described. FIG. 4 shows a situation where the weed control material solidified product 8 according to an embodiment of the present invention is applied to the site of a power transmission line.

[0045] Since power transmission lines are often in places where people have difficulty entering, the sites of power transmission lines are greened from the perspective of landscape. Plants for greening may have an adverse impact on security, appearance, and function if they grow too much.

[0046] As shown in the figure, a plurality of weed control material solidified products 8 are spread around the base portion of the tower 12 at the site of the power transmission line 11 (the solidified body 5 and solid particles 6 are appropriately spread depending on the location). A plurality of weed control material solidified products 8 are spread in a desired range around the base block 12a of the tower 12. Also, on the access path 13 to the tower 12, a plurality of weed control material solidified products are spread along the path.

[0047] The weed control material solidified product 8 has a suppression member containing component elements having a weed control effect of inhibiting the growth of the plant 14 and regulating its growth, and the component elements elute. Therefore, around the base block 12a of the tower 12 and on the access path 13 to the tower 12, the size, color, flowering time, etc. of the leaves, roots, and stems, which are the forms of the plant 14, are arbitrarily adjusted, and the growth state is controlled to a desired state, and the state of the desired size, color, etc. is maintained without maintenance.

[0048] With a simple construction of just spreading the weed control material solidified product 8, the form of the plant 14 around the base block 12a of the tower 12 and on the access path 13 to the tower 12 is adjusted, the growth state is controlled, and the state of the desired size, color, etc. is maintained. As a result, it becomes possible to maintain (control) the form (size, color, flowering time, etc.) of the plant 14 within a predetermined range, and it is possible to suppress the growth of plants around the base block 12a of the tower 12 and with respect to the tower 12 more than necessary.

[0049] That is, plants around the foundation block 12a of the iron tower 12 (the base of the iron tower 12), which is a difficult-to-access location, can be maintained with low grass for a long time, which is advantageous for the landscape and facility protection. Also, by constructing a weed-suppressing material solidified product on the access road 13 to the iron tower 12 in the mountainous area and controlling (adjusting) to maintain the plants 14 with low grass for a long time, the access road 13 can be secured for a long time without requiring special maintenance.

[0050] Based on FIGS. 5 to 8, the performance of the weed-suppressing material solidified product 8 will be described.

[0051] FIG. 5 shows the relationship between the ratio of blast furnace slag powder (SL) and unburned shell powder (SP), which are solidifying members for the auxiliary material, and the strength. FIG. 6 shows an example of the relationship between the strength and the elution amount of the suppressing member. Also, FIG. 7(a) shows the change over time in the elution amount of aluminum (Al), FIG. 7(b) shows the change over time in the elution amount of sodium (Na), FIG. 8(a) shows the change over time in the elution amount of boron (B), and FIG. 8(b) shows the change over time in the elution amount of lithium (Li).

[0052] As shown in FIG. 5, when the fly ash 1 is constant, as the amounts of blast furnace slag powder (SL) and unburned shell powder (SP), which are solidifying agents among the auxiliary materials, increase, the strength of the weed-suppressing material solidified product 8 increases.

[0053] Therefore, by adjusting the amounts of blast furnace slag powder (SL) and unburned shell powder (SP), a weed-suppressing material solidified product 8 having a desired strength can be produced. And by adjusting the amounts of blast furnace slag powder (SL) and unburned shell powder (SP), solidified products of various shapes (structures) can be produced. For example, a weed-suppressing material solidified product in the shape of a garden ornament can be produced.

[0054] As shown by an example in FIG. 6, when the fly ash 1 is constant, as the strength of the weed-suppressing material solidified product 8 increases, the elution amount of the suppressing member (metal) decreases. Therefore, by maintaining the strength in a state where it does not become too high, the elution amount of the suppressing member (metal) can be maintained more than necessary.

[0055] When shown as an example in FIG. 6, when the strength is lowered, the strength of the solidified product as the desired shape decreases, but the elution amount of the suppression member (metal) can be sufficiently ensured to produce a granular solidified product.

[0056] Therefore, by variously selecting the mixing ratios of the suppression member as the main material, the solidifying agent as the auxiliary material, and the solidification accelerator, it becomes possible to produce the weed-suppressing material solidified product 8 in a desired form (structure, granular solid).

[0057] For example, by spreading the solid particles 6 on the periphery of the curb portion such as the corner of the sidewalk at the intersection, the growth of plants growing around the curb portion can be suppressed. In the curb portion, sand, soil, fallen leaves, etc. tend to accumulate, and there is a risk of plant (weed) growth in the compost. By spreading the solidified product of the granular suppression member, the growth of plants (weeds) around the curb portion is suppressed even if sediment accumulates.

[0058] As shown in FIGS. 7 and 8, although the tendency of the variation in the elution amount is different for the elution amount of aluminum (Al), the elution amount of sodium (Na), the elution amount of boron (B), and the elution amount of lithium (Li), it was confirmed that the metal component was eluted from the weed-suppressing material solidified product 8 even after the passage of time (months) (for example, even after about 9 months).

[0059] Even after the passage of time (months) (for example, even after about 9 months), the elution of the metal component from the weed-suppressing material solidified product 8 is maintained, while depending on the type of component element, the period when the concentration in the soil solution is high is different. Therefore, by selecting the suppression member, it is possible to obtain the weed-suppressing material solidified product 8 that suppresses growth at a desired time according to the purpose of use.

[0060] By installing the weed-suppressing material solidified product of the present invention at a desired location, it becomes possible to adjust the form (size, color, flowering time, etc.) of the plant and maintain (control) the form of the plant.
