DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a covering material for protecting plants, that is, a mulching material used to cover the root of a plant, and more particularly to a mulching material having a sheet shape as a whole.

[0002]

2. Description of the Related Art In order for plants to grow smoothly, it is necessary that the roots have sufficient moisture and that the environment conditions are as warm as possible. In order to prevent the fertilizer given to the planted plant from being absorbed by other weeds, it is necessary to perform a weeding operation in order to make the plant grow sufficiently. In particular, when artificially performing vegetation on slopes or planting trees on wasteland, if the cost of vegetation is reduced by ensuring that the growth of plants after construction is smooth, the above-mentioned environmental conditions should be sufficiently prepared. In addition, weeding needs to be performed regularly.

[0003] In particular, when trees are to be grown on cut slopes or seashores, so-called "pot seedlings" (usually seedlings) grown in pots made of synthetic resin or the like. In order to grow this pot seedling sufficiently, it is important to ensure the above conditions.

[0004] In order to keep the pot seedling and the surrounding soil warm and moist, it is conceivable to lay a mulching material at the root of the seedling. As a mulching material for plants, “mulch” composed of synthetic resin sheets is well known, but this mulch is mainly used to prevent grass growth while expecting a greenhouse effect at the root. Have been. A mulch made of such a synthetic resin sheet,
Although it can be provided at a low cost, it uses a synthetic resin that does not rot to the last, which makes it difficult to treat it after use. In addition, since the mulch is formed thinly from a synthetic resin sheet, the mulch is easily broken at the time of construction in Yamano, and cannot be used.

For this reason, as a mulching material for this kind of pot seedling, as shown in FIG. 9, a rice straw member has conventionally been used. In the conventional example shown in FIG. 9, a large amount of rice straw is spread over the surface soil, a straw rope for preventing scattering is put on the upper surface of the rice straw, and the straw rope for preventing scattering is pinched with a U-shaped wire or the like. It is intended to stop. This rice straw has sufficient heat retention and moisture retention, and is returned to the soil 2 to 4 years after the pot seedlings have sufficiently grown, and thus is very useful as a plant fertilizer.

However, mulching materials using such a large amount of rice straw require a great deal of labor to apply it to a slope or the like, and its use is difficult. There is a problem that it easily breaks apart. In particular, rice straw that is merely laid or held with straw rope tends to have gaps that allow sunlight to reach the surface soil, which makes it easy for weeds to grow. In addition, in Japan in recent years, it has become very difficult to obtain rice straw in large quantities, and construction for plant protection using rice straw in large quantities as shown in FIG. It is very difficult in practice.

The inventors of the present invention have conducted various studies on how to achieve a sufficient plant-protecting effect by using straw members of rice and wheat, and as a result, completed the present invention. It is.

[0008]

SUMMARY OF THE INVENTION The present invention has been made on the basis of the above circumstances, and the problem to be solved is to provide a mulching material for protecting plants by using rice straw or the like. In doing so, the effect should be sufficient.

That is, the object of the present invention is to
An object of the present invention is to provide a mulching material having a high heat retention, moisture retention and weed control effect, which can be supplied stably and inexpensively, and which can sufficiently protect plants with a simple configuration.

[0010]

In order to solve the above problems BRIEF SUMMARY OF THE INVENTION, means of adopting the present onset Ming is explained with reference numeral used in the description of the embodiments described later, "planted covering the roots and soil surface near its straight object P, these plants P and soil warmth and moisturizing such protection and surrounding soil
To bring weed control to the weeds
A mulching material 10 ;
Weed control sheet 11 applied to the root of plant P and this weed control
A straw member 1 sewn to the surface of the sheet 11 without gaps
2 and the grass sheet 1111 is hemp or the like.
Composed of vegetable fiber and biodegradable blended material such as rayon
Then, the straw member 12 is made of rice straw, wheat straw or kayak.
A mulching material 10 "characterized by being formed from a plant drying material .

[0011] That is, Ma Ruchingu member 10 this is made by laminating a straw member 12 on the surface of the substrate sheet 11a,
At least two places thereof are sewn together with a needle processing part 13a, and the root of the planted spot P and the soil surface around the root are covered, and these plants and soil are kept warm and moist. In this case, weeds are provided with a weed control effect.

(Delete)

Further, the mulching material 10 according to the present invention comprises:
Basically, it has a straw member 12 in which dried plant bodies such as rice straw, wheat straw, and kayak are overlapped with a certain thickness. Then, in order to prevent the straw members 12 made of these dried plant bodies from falling apart, plant fibers such as hemp, jute and cotton are used as a main material on the back side of the straw members 12 to corrode them in a natural environment. It is lined with a weedproof sheet 11 mixed with rayon or the like, which is easy to do.

As shown in FIGS. 6 to 8, the mulching material 10 is prepared by directly contacting a herbicidal sheet 11 made of plant fibers such as hemp and rayon with the soil surface around the root of the plant P. If the contacting surface is the soil surface, it literally prevents the growth of weeds and retains water, or protects the soil surface around the plant P in contact with the weed prevention sheet 11 from cold (heat retention). And also keeps water. Because this weed control sheet 11
This is because light hardly passes through the surface of the earth. The straw member 12 on the surface side of the grass sheet 11 keeps the surface of the soil warm and water-retained.
0 means that the plant P is sufficiently protected and its growth is assisted.

Of course, since the straw member 12 is sewn on the surface of the grass sheet 11 with the sewing thread 13, it is not necessary to use it in a large amount as in the conventional construction method shown in FIG. In addition, the surface of the topsoil and the like can be reliably covered with a small amount of rice straw, wheat straw, or the like without any gaps for heat insulation. Moreover, since the rice straw and the like are sewn to the grass sheet 11 with the sewing thread 13, they are not blown by the wind and completely cover the soil surface around the root of the plant P over a long period of time. It is stable.

As described above, the mulching material 10 is composed of a weed prevention sheet 11 which is a blended material of vegetable fibers such as hemp and rayon and a straw member 12 in which rice straw and the like are spread.
When the pot seedling shown in FIG. 7 or FIG. 8 is planted on the slope 20 or the like, for example, when the pot seedling shown in FIG.
As shown in the figure, the slope 2
Then, a knife is inserted in the direction of the straw of the straw member 12 and a cut is made in the lower grass-proof sheet 11. The plant P is planted from this cut, and the weed control sheet 11 and the straw member 12 are slightly leveled.
Since the mulching material 10 can be completely covered by zero, the mulching material 10 can be worked very easily.

The mulching material 10 is decomposed by microorganisms in the soil when placed in a natural environment, whether it is the grass sheet 11 or the straw member 12,
The plant P such as a pot seedling is completely decomposed two to six years after it grows sufficiently, and becomes a nutrient of these plants P, that is, a fertilizer. Of course, until this complete disassembly,
It goes without saying that the above-mentioned heat-retaining, water-retaining and herbicidal effects for the plant P are exhibited.

The mulching material 10 is formed by using a weed-proof sheet 11 that can be factory-produced throughout the year and a straw member 12 that has been sufficiently dried, and using a sewing thread 13 to integrate them. Therefore, for example, by storing and storing in a bag made of a synthetic resin film or sheet, stable supply can be sufficiently performed throughout the year. In particular, the fact that the whole is made into a sheet means that it can be rolled up, so that it can be stably stored.

Therefore, the mulching material 10 according to the present invention
Can be supplied stably throughout the year, and its construction work can be easily performed on slopes, etc., and sufficiently protects plant P from seedlings such as pot seedlings. It is simple enough.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a mulching material 10 according to the present invention configured as described above will be described with reference to the embodiment shown in the drawings. FIGS. The entire mulching material 10 is shown. As shown in FIG. 2 and FIG. 5, the mulching material 10 is a sheet-like base material 11a or a weed control sheet 11 on the surface
The dried plant such as rice straw is needle-processed on the surface of
a or sewn with the sewing thread 13, and the dried plant is a straw member 12. In other words, the mulching material 10 basically uses the straw member 12 having a certain thickness overlapped. In order to prevent the straw member 12 from falling apart, The sheet-shaped base material 11a or the grass-proof sheet 11 is backed.

The sheet-like base material 11a may be any material as long as it can support the straw member 12 in a planar manner. On the other hand, the grass-proof sheet 11 is made of a material having a certain degree of limitation, as will be described later. On the other hand, in the mulching material 10 shown in FIG. 1, the straw members 12 constituting the mulching material 10 are laminated to a constant thickness. And a notch 14 for inserting a seedling.

As the weed control sheet 11, plant fibers such as hemp, jute and cotton which are easily completely corroded in the soil (all of which are already used for something and so-called reusable ones are sufficient). The main material is a sheet made by blending rayon or the like which is easily corroded. That is,
The weed prevention sheet 11 may be made of a mixed fiber of vegetable fiber and rayon or the like, and may be used as a woven fabric or a nonwoven fabric of the mixed fiber. Rayon is considered to be insufficient in strength when formed into a sheet only with vegetable fibers such as cotton, and is used for compensating for the overall strength.

In this embodiment, about 10 to 50% of rayon is mixed in the plant fiber. And completely corroded by microorganisms in the soil.

The straw member 12 is made of a dried plant such as rice straw, wheat straw or kaya literally.
Not only domestic products but also foreign products are used. Wheat straw for constituting the straw member 12 can be obtained in early summer, rice straw and kayak can be obtained in autumn, and if foreign products are used, a sufficient supply can be obtained almost throughout the year. In order to make such a rice straw a straw member 12,
It is appropriate that this is spread about 3 to 5 kg / m ^{2 with} respect to the above-mentioned weed prevention sheet 11.

The sewing thread 13 for integrating the straw member 12 with the surface of the grass sheet 11 may be formed of the above-mentioned rayon or a rope formed of vegetable fibers such as jute. It may be.
In any case, the sewing thread 13 may be any material that can completely corrode with the grass sheet 11 and the straw member 12 in about two to six years.

Now, in order to protect the plant P using the mulching material 10 configured as described above, FIGS.
It is good to do as shown in.

6 shows a construction example in which the plant P, which is a so-called "pot seedling", is protected.
The mulching materials 10 are arranged at predetermined intervals on the slab 0, but are cut into mulching materials 10 having an area capable of sufficiently protecting the roots of the plants P, and the mulching materials 10 are arranged at appropriate intervals. Of course, the plant P is planted on the slope 20 through each of the mulching materials 10. Vegetation plant spraying is performed on the topsoil between the mulching materials 10 as necessary. Even with such spraying work,
As described above, since each plant P is protected by the mulching material 10, the vegetation plant cannot grow on the soil around the plant P and, as a result, does not absorb the fertilizer.

Such construction is performed on the ground where greening is required in a factory, on a residential land development site, a slope 20 beside a road, a slope of a dam, or the like.
Suitable for dry ground.

FIG. 7 shows a construction method in which a pot seedling is planted on the slope 20 and the mulching material 10 according to the present invention is attached to the whole. In this case, the wound mulching material 10
Need only be rolled over the slope 20, but the planting of each plant P on the slope 20 may be performed before or after the mulching material 10 is developed.

Such a construction is suitable for a soil having a relatively large amount of nutrients in the soil, such as a residential land development site, a slope 20 beside a road, a slope of a dam, etc., but having a high level of dryness.

8 is basically the same as the method shown in FIG. 7, except that soil is applied to the surface of the slope 20 so that the soil does not flow. Are protected by M.

This construction method has a low nutrient content in the soil,
It is also suitable for dry land.
