Description

  The present invention relates to a weeding material and a weeding method, and more particularly, to a weeding material for selectively killing vine plants such as kudzu and rough terrain and rhizomes such as horsetail and a weeding method using the same.

  As greening land, green areas of roads and green areas of rivers have been constructed, and various vegetation is carried out. For example, vegetation for protecting the slope is provided on the highway slope. However, over time, these types of weeds, such as vines such as kudzu and rough terrain, and rhizomes such as horsetail, are mixed in over time. Necessity comes out.

When a herbicide is sprayed for weeding such a weed, there is a problem that not only vines and rhizomes but also weeds that fix highway slopes are weeded. If even weeds that fix the slope are weeded, it becomes difficult to maintain the slope, and landslide may occur due to heavy rain.
Therefore, a method for selectively weeding weeds has been proposed. For example, a method is known in which a herbicide is injected by making a hole in the stem of a vine (see Patent Document 1).

JP-A-10-167902

However, in the method described in the above-mentioned patent document, it is necessary to open a hole of a predetermined size and a predetermined depth in the vine plant to be weeded, and since the herbicide is injected from the hole, the working efficiency is inferior. There is a problem.
The present invention has been made to solve the above-mentioned problems, and the object of the present invention is to use weeding materials capable of selectively weeding weeds and further improving work efficiency, and the same. It is to provide a weeding method.

  Hereinafter, embodiments of the weeding material and the weeding method according to the present invention will be described with reference to the drawings.

<First embodiment>
FIG. 1 is a perspective view showing an outline of the weeding material 1 according to the first embodiment of the present invention. The weeding material 1 includes a container (herbicidal material container) 2 and a lid 4.
As shown in the assembly diagram of FIG. 1, a screw thread 10 into which the lid 4 is screwed is formed on the outer periphery of the spout portion 8 of the container 2. A through-hole 6 having a predetermined size is formed in the lid 4. Further, as shown in FIG. 3 which is a cross-sectional view taken along the line III-III in FIG. 1, a female screw 12 is formed on the inner periphery of the lid 4 so as to be screwed into and engaged with a screw thread 10.

The container 2 and the lid 4 are preferably formed of a biodegradable material that is decomposed by microorganisms. An example of a biodegradable material is a biodegradable resin. Examples of the biodegradable resin include fatty acid polyester resin, starch, polylactic acid resin, and cellulose.
The through-hole 6 provided in the lid 4 serves as an insertion port for inserting a damaged part of the plant to be weeded into the container 2 as described later.

  A herbicidal material 14 containing a herbicide is accommodated in the container 2. The herbicide 14 is a semi-solid herbicide in which a herbicide is mixed with a gelling agent. The gelling agent used in this example preferably has biodegradability. The size of the container 2 and the through-hole 6 is not particularly limited, but is preferably a size that can contain the roots and stems of plants to be weeded.

  Although the herbicide used for the herbicide 14 will not be restricted especially if it is used as a herbicide, For example, a roundup (trademark) etc. are mentioned. The herbicidal material 14 is preferably made of a material that prevents the herbicide from leaking out of the container 2 or evaporating. In this embodiment, the herbicide is mixed with the gelling agent and the semi-solid herbicide 14 is accommodated in the container 2 so that the herbicide contained in the herbicide 14 evaporates or volatilizes from the container 2. Can be suppressed.

  The amount of the herbicidal material 14 accommodated in the container 2 is not particularly limited, but is absorbed by the roots and stems of the herbicidal target plants into which the herbicide component contained in the herbicidal material 14 is inserted, for a predetermined period, for example, 2 weeks. It is preferable to set the amount so as to be almost eliminated. Thus, even if the container 2 into which a part of the plant to be weeded is inserted is left and the container 2 is decomposed by microorganisms and the herbicide 14 may be exposed from the container 2, the herbicide Since the herbicide component contained in 14 is almost absorbed by the plant to be weeded, it can be prevented from affecting the surrounding environment. Moreover, since the gelatinizer used for formation of the herbicidal material 14 also has biodegradability, the same effect can be acquired.

  Next, the weeding method using the weeding material 1 configured as described above will be described. A herbicidal material 1 is cut into a herbicidal plant, such as a stem or a root of kudzu or horsetail, and the stem or root tissue is damaged by breakage or the like. Plug in. The herbicide is absorbed from the damaged part of the plant to be weeded inserted into the herbicidal material 14, and the plant to be weeded is killed.

  As described above, in this embodiment, the herbicide 14 in which the herbicide is mixed with the gelling agent is placed in the container 2 formed of the biodegradable resin, and the damaged portion of the stem or root of the plant to be weeded is herbicide. Since the plant to be weeded can be selectively withered by being inserted into 14, the working efficiency can be improved. Moreover, since the herbicidal agent can be removed with a smaller amount of herbicide than when the herbicide is sprayed, the cost for the herbicidal treatment can be reduced.

  In addition, since the container 2 and the lid 4 are made of a biodegradable resin, the container 2 and the lid 4 are made of microorganisms or the like even if the damaged portion of the plant to be weeded is inserted into the container 2 and left as it is. Therefore, it is not necessary to collect the weeding material 1, so that weeding workability can be further improved and the cost required for weeding can be reduced.

A modification of the present embodiment will be described below. In this modification, the shape of the container 2a is a pack. In detail, it demonstrates based on the perspective view which shows the outline of the weeding material 1a shown in FIG. 4, and sectional drawing which follows the VV line | wire of FIG. 4 shown in FIG.
As shown in FIG. 4, the weeding material 1 a includes a container (herbicidal material container) 2 a, and a through hole 6 a is formed on the surface on which the joint portion 20 is provided. Here, the surface on which the through-hole 6a is provided is defined as the top.

  In the container 2a, the sheet-like base material 16 is formed in a pack shape so that the contents can be accommodated therein, and the sheet-like base material 16 is joined at a predetermined position along the longitudinal direction of the upper surface 18 of the container 2a. The joining part 20 is provided. In addition, although not shown in figure, the bottom face 22 of the container 2a is also provided with the junction part of the sheet-like base material 16 similarly.

As shown in FIG. 5, a herbicidal material 14a containing a herbicide is accommodated in the container 2a. The composition of the herbicidal material 14a is the same as that in the above-described example.
The sheet-like substrate 16 forming the container 2a is preferably a biodegradable material that can accommodate the herbicidal material 14a and is decomposed by microorganisms. Examples of biodegradable materials include biodegradable resins and plant-based materials.

  Examples of the biodegradable resin include fatty acid polyester resin, starch, polylactic acid resin, and cellulose. Moreover, the paper base material used as a container is mentioned as plant-type material. Examples of the paper base include natural paper, synthetic paper, and mixed paper.

Such a biodegradable resin or plant material may be used alone as the sheet-like substrate 16 to form the container 2a, or a mixture of these materials may be used. When the container 2a is formed of the sheet-like base material 16 of the biodegradable resin, the biodegradable resin may be heated and softened, and the herbicide 14 may be accommodated and formed into a pack shape. Moreover, when the container 2a is formed with the sheet-like base material 16 of plant material, the herbicide 14a is accommodated before forming the joint part 20, and it joins in the joint part 20 and forms in a pack shape. May be.
By adopting such a configuration, it is possible to obtain the same effect as in the above-described embodiment. Moreover, since the container 2 is formed from a biodegradable material, the same effect as the said Example can be acquired.

<Second embodiment>
The weeding material 1b according to the second embodiment of the present invention will be described below. The weeding material 1b according to the present embodiment differs from the first embodiment in that a porous water retaining material is used as the weeding material 1b and a sheet-like base material of biodegradable resin is used as a container. The configuration is the same. Therefore, the description of the common part is omitted, and the difference is described.

  In FIG. 6, the schematic of the weeding material 1b which concerns on 2nd Example of this invention is shown. The weeding material 1 b includes a wrapping bag (herbicidal material container) 30 formed from the sheet-like base material 16 b and a weeding material 14 b accommodated in the wrapping bag 30.

  The herbicidal material 14b accommodated in the wrapping bag 30 is obtained by impregnating a porous sponge 32 having water absorption and water retention with a herbicide. The water-retaining material 32 is a material that has biodegradability and can insert a damaged portion of a plant to be weeded, and examples thereof include sponges and sponges. The size of the water-retaining material 32 is not particularly limited, but is preferably a size that can insert the damaged portion of the plant to be weeded.

  The transparent sheet-like base material 16b that forms the sachet 30 is made of a biodegradable resin. The thickness of the sheet-like base material 16b is preferably a thickness that can be broken and opened when the damaged part of the plant to be weeded is pressed against the sheet-like base material 16b. The outer periphery of the wrapping bag 30 is joined at the joining portion 34 over the entire circumference. The joint 34 is formed by crimping or welding the end of the bag 30. By forming the joint 34 in this way, the herbicidal material 14 b is sealed in the bag 30.

  Next, a weeding method using the weeding material 1b configured as described above will be described. When the damaged portion of the stem or root of the plant to be weeded is pressed against the wrapping bag 30 of the weeding material 1b, the pressed portion of the wrapping bag 30 is broken and opened, and the damaged portion is inserted into the wrapping bag 30 through the opening. And insert into the weeding material 14b.

  Thus, in this embodiment, the herbicide target plant is destroyed by sealing the water retaining material 32 impregnated with the herbicide in the sachet 30 formed from the sheet-like base material 16b made of biodegradable resin. Since the part can be inserted into the herbicidal material 14b from any place of the bag 30, the working efficiency can be further improved. Further, the same effect as in the first embodiment can be obtained.

(Modification of weeding material)
Next, modifications of the present embodiment will be described below. In this modification, the herbicidal material is housed in a bottomed cylinder, and the cylinder is sealed with a lid. In detail, it demonstrates based on the schematic of the weeding material 1c shown in FIG. 7, and sectional drawing in alignment with the VIII-VIII line of FIG. 7 shown in FIG.

As shown in FIG. 7, the weeding material 1c includes a bottomed cylindrical container 2c and a lid 36 that covers the opening of the container 2c.
As shown in FIG. 8, a herbicidal material 14c is accommodated in the container 2c. The herbicidal material 14c is obtained by impregnating the water retaining material 32c with a herbicide.

  The container 2c is formed from a biodegradable resin, a wood material, or a bamboo material (plant material). Here, the wood-based material may be, for example, raw wood or lumber, but may be thinned wood, unused wood, or construction waste. The container 2c may be formed by cutting such wood, or the container 2c may be formed by processing a plate made of wood, chipped, molded with an adhesive, and hot-pressed. When the container 2c is formed from a bamboo material, it is preferably cut so that one bamboo node is included.

  At the opening end of the container 2c, there is a joint 38 that joins the lid 36. The joining portion may be joined with an adhesive, or may be joined by pressure bonding. The lid 36 that covers the open end of the container 2c is a resin film formed from a biodegradable resin. The thickness of the resin film is not particularly limited, but is preferably a thickness that can be broken and opened by pressing the damaged part of the plant to be weeded. By joining the lid 36 to the open end of the container 2c, the container 2c is sealed, so that the herbicide contained in the water retaining material 32c can be prevented from evaporating and volatilizing.

A weeding method using the weeding material 1c configured as described above will be described. The cover 2c of the herbicidal material 1c is pressed at the damaged part of the plant to be weeded, and the damaged part is inserted into the container 2c from the opening opened by breaking and inserted into the herbicidal material 14c.
As described above, the water retaining material 32c impregnated with the herbicide is placed in the container 2c formed of a biodegradable resin or a plant-based material, and the container 2c is sealed with the lid 2c. The effect of can be obtained. Moreover, manufacturing cost can be suppressed by manufacturing the container 2c from plant-type materials, such as a timber and bamboo.

Another modification of the present embodiment will be described below. In this modification, the herbicidal material 14d is covered with a biodegradable resin film and accommodated in a container having a window portion. In detail, it demonstrates based on the perspective view of the weeding material shown in FIG. 9, and sectional drawing which follows the XX line of FIG. 9 shown in FIG.
As shown in FIG. 9, the weeding material 1d further contains a weeding material 14d covered with a biodegradable resin film (herbicidal material container) 42 and a weeding material 14d covered with the resin film 42. 2d.

  The container 2d is provided with a window 40 cut out in a predetermined size on each surface. As will be described later, the window 40 serves as an insertion port for inserting a damaged portion of the plant to be weeded. In addition, although the container 2d shown in FIG. 9 is provided with one window portion 40 on each surface, a plurality of window portions 40 may be provided on each surface, or a different number of window portions 40 may be provided for each surface. You may make it provide.

  The container 2d is formed from a biodegradable resin or a plant material. The weeding material 14d covered with the resin film 42 is obtained by impregnating a water retaining material 32d with a herbicide. Since the herbicidal material 14d is sealed by being covered with the resin film 42, evaporation and volatilization of the herbicide contained in the water retaining material 32d can be prevented. In order to accommodate the herbicidal material 14d in the container 2d, any one surface may be opened, and the opened one surface may be joined to the other surface after the weeding material 14d is accommodated in the container 2d.

A weeding method using such a weeding material 1d will be described. The resin film 42 is pressed from the window part 40 of the weeding material 1d at the damaged part of the plant to be weeded, the resin film 42 of the pressing part is broken and opened, and the damaged part is inserted into the herbicidal material 14d.
Thus, by covering the herbicidal material 14d with the resin film 42 made of a biodegradable resin and storing it in the container 2d provided with the window 40, the plant to be weeded from the window 40 on any surface. Since the damaged portion can be inserted into the herbicidal material 14d, the same effect as in the second embodiment can be obtained.

  Next, another example of the above modification will be described below. FIG. 11 is a perspective view showing an outline of the weeding material 1e, and FIG. 12 is a sectional view taken along the line XII-XII of FIG. 11, and the weeding material 1e includes a spherical water retaining material 32e of a predetermined size. The surface of the herbicidal material 14e impregnated with the herbicide is covered with a container 2e, 2e in which a resin film is formed in a substantially hemispherical shape and joined to provide a joint 44, and the herbicidal material 14e is sealed in the container 2e, 2e. You may make it do. In addition, in FIG. 11, 12, although the shape of the weeding material 14e was made into the spherical body, a shape is not restricted to this. Moreover, it is preferable that the shape of the container 2e which coat | covers the weeding material 14e is formed according to the shape of the weeding material 14e.

Although the description of the embodiment is finished as described above, the present invention is not limited to the above-described embodiment.
For example, in each of the above-described examples, the herbicide 14 in which the herbicide is blended with the gelling agent and the herbicide 14b in which the herbicide 32 is impregnated with the herbicide 32 are used. Further, a herbicidal material may be obtained by impregnating a non-woven fabric, woven fabric, cotton or the like having water retention with a herbicide.

Moreover, in each said Example, although the herbicides 14 and 14a-14e contain the herbicide, you may mix the component (fertilizer component) used as a plant fertilizer further in the herbicides 14 and 14a-14e. .
Some vines and rhizomes, such as kudzu, can be killed to some extent by inserting them into one of the weeding materials 1, 1a to 1e, but kudzu are harmful to what they inhale If you recognize, you may cut off the part that has already absorbed the herbicide. For this reason, some of the kudzu may remain undead.

  In order to improve the absorbability of such herbicides to plants, plant fertilizer components may be mixed when preparing the herbicides 14, 14a to 14e. Examples of components that become fertilizers include sugars and amino acids. By including plant fertilizer components in the herbicides 14, 14a to 14e, the vine plants and the rhizome plants recognize the nutrients and absorb them together with the herbicides, so that the effects of the herbicides can be further improved. But we can be surely weeded.

Moreover, in each Example mentioned above, although various shapes were shown about the weeding material and the container, it is not restricted to this, It can change in the range which does not deviate from the objective of this invention.
Further, combinations and various modifications of the above-described embodiments are possible without departing from the object of the present invention.
