Abstract

PURPOSE: To form a multi-material provided with effect as a conventional multi- material and matched even with a surrounding beautiful environment by compounding barks and small sized chips obtained from a trunk of a tree.

CONSTITUTION: This multi-material is compounded with the barks and the small sized chips obtained from the trunk of a tree and formed. Since a weed does not grow at the place where the multi-material is paved, when a herbicide is added to the above blending, this multi-material is preferred. A broadleaf tree such as keyaki (Japanese tree name) and kunugi (a kind of oak), is preferred as the barks rather than a conifer tree. The shape of the barks can be used a flat one having, e.g. about 5-20 cm length, ≤ about 5 cm width and ≤about 1 cm thickness. The chips are produced by peeling the barks from the trunk of material wood such as the broadleaf tree and the conifer tree, and making the chips by cutting, and the flat chips having, e.g. ≤ about 10 mm height and width are used.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention can be applied to the lower part of a tree or other ground surface,
Regarding mulch materials that cover soil.

<Prior art and its problems> As a conventional multi-purpose material, there is, for example, a plastic film that belongs to the first type. For example, by covering the ridges of a field, this has the effect of preventing leaching of nutrients from the soil, increasing soil temperature, reducing water evaporation from the soil surface, and suppressing weeds. . However, these plastic films and the like do not themselves serve as fertilizer, nor do they improve the soil itself.

On the other hand, as mulch materials belonging to the second type, in addition to the mulching effect of covering the ground surface, there are materials that have the effect of acting as fertilizer or improving soil. This includes, for example, mulch, peat moss, bark compost, etc.

However, both of the mulch materials belonging to the first and second types above have a strong feeling that they are exclusive materials for protecting or growing vegetation, and at least their use does not match the aesthetic surroundings. Ta. In other words, conventional mulch materials can be used in situations where a certain aesthetic environment is required, such as in garden construction, park construction, road greening construction, slope greening construction, etc., and can be used to harmonize and become part of the aesthetic environment. It wasn't something I would do.

<Purpose> Therefore, the present invention aims to provide a mulch material that has the effects of conventional mulch materials and also harmonizes with the surrounding aesthetic environment.

<Means for Solving the Problems> The mulch material of the present invention that solves the above problems is characterized by containing bark compost and chips obtained from tree trunks. Another aspect of the method is that a herbicide is added thereto.

The bark compost is made by adding a nitrogen source to the bark of broad-leaved trees or coniferous trees, and fermenting and ripening the bark.

In addition, the above-mentioned chip can be used to cut the trunk of a broad-leaved or coniferous tree into 111
The size of 9 chips, which are made into chips by peeling, cutting, etc., is usually 10 to 3011 in length and 3011 in width, and 3 in thickness.
~5 friends, but is not limited to this.

Use a flat shape. By making it flat, it becomes easier to lay it on the ground, provides better ground coverage, and makes it easier for people to walk on it. In addition, the wood chips generated when manufacturing chips by cutting etc. are 1011 mm in length and width.
The flat pieces shown below are not powders, but can also be used as "chips." In the present invention, the wood chips are also included in the scope of "chips".

By blending the chips, the wood scent of the chips provides a kind of forest bathing environment to the surrounding area. Therefore, it is preferable to use wood for the chips that has a good aroma, such as cedar or cypress.

The mixing ratio of bark compost and chips is not particularly limited, but in order to achieve good mixing of both, it is preferable that the volume ratio of chips to bark compost is about 10 to 70%.

The mulch material of the present invention can be effectively used not only in fields but also in gardens, parks, road green belts, slope green areas, etc. However, it can also be laid on other ground surfaces.

For example, mulch material may be spread over trees and other parts of the garden. By placing it in areas other than trees, the overall harmony can be achieved in terms of color and other relationships with the surrounding area. The thickness of the layer laid on the ground can be, for example, from 50 to 1001 mm.

A herbicide may be added to the mulch material of the present invention. As the herbicide, various herbicides can be used, for example, in addition to triazine herbicides such as the trade name Simazine.
They can be used by adding appropriate amounts as needed. By adding herbicides, weeds will not grow where the mulch material is spread.

Functional Effects> The mulch material of the present invention has the above-mentioned structure, and contains bark compost and chips obtained from tree trunks, so by spreading it on the ground surface, it removes moisture in the soil. It prevents evaporation and drying, prevents leaching of nutrients in the soil, and maintains soil temperature. Moreover, the bark compost can provide nutrients to the soil and improve the soil. Moreover, since the chips added to bark compost are also obtained from trees, they gradually decompose, providing nutrients to the soil and improving soil quality, just like humus.

Furthermore, since the chips used in the present invention are not in powder form, by spreading a mixture of them and bark compost on the ground, in addition to retaining water in the soil and preventing it from drying out, it also ensures air circulation into the soil. be done.

In particular, since the present invention contains chips, it is easy to walk on the mulch material spread on the ground. Also, since the top surface of the chips dries properly, the feet are less likely to get wet compared to when using only bark compost.

In addition, by incorporating chips, it retains the functionality and aesthetics of a mat material laid on the ground, and by laying it on areas other than the roots of trees, it harmonizes with the overall aesthetics and environment of gardens, parks, etc. can be done.

Furthermore, in the present invention, since the chips are obtained from tree trunks, after being laid, the pleasant scent of the tree spreads to the surrounding area, which has a great effect of creating a good environment.

In addition, adding a herbicide is effective because it prevents weeds from breeding in the area where it is installed.
