Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizer-containing mat which is laid on a slope of a road or a green belt to protect planted seedlings.

[0002]

2. Description of the Related Art Generally, in order to protect an inclined slope along a road, trees are planted on the slope to prevent landslides.
Conventionally, after constructing slopes, saplings were planted here at appropriate intervals, and straw or Como was laid on the slopes to prevent weeds from growing, while fertilizing until the saplings grew until they grew. . However, since the slope is steep, the straw and Como laid to prevent weeds are blown by the wind, and the ground is exposed by being washed away by rainwater, where weeds grow and hinder the growth of seedlings. I was sometimes told. In addition, it is necessary to sprinkle fertilizer on the seedlings from time to time, but the work of spraying on steep slopes is labor-intensive and laborious.

[0003]

DISCLOSURE OF THE INVENTION The present invention eliminates the above-mentioned drawbacks, and even if a mat is laid on a slope or a green belt and a sapling is planted here, the ground is exposed even if it is left as it is. In addition to suppressing the growth of weeds, the fertilizer content exudes over a long period of time and the fertilizer is continuously supplied to the seedlings.
Moreover, it provides a fertilizer-containing mat that composts itself into soil after the seedlings have grown over the years.

[0004]

The fertilizer-containing mat according to claim 1 of the present invention is a woven or non-woven fabric of vegetable fibers or paper impregnated with liquid fertilizer to form an impregnated sheet,
Two of these impregnated sheets are stacked and the solid fertilizer is stored between them, and the upper and lower impregnated sheets are pressure-bonded in a quilted manner at predetermined intervals to hold the solid fertilizer.

The invention according to claim 2 is characterized in that the solid fertilizer is adhered to an impregnated sheet with an adhesive. Further, the invention according to claim 3 is characterized in that the solid fertilizer is mixed with seeds.

[0006]

The fertilizer-containing mat of the present invention is laid on a slope or on a green belt, and the fertilizer-containing mat is cut at intervals of planting seedlings, and the fertilizer-containing mat is opened to dig holes to plant seedlings. The solid fertilizer does not move because it is held in the quilted space that is crimped between the upper and lower two impregnated sheets. If you leave it in this state, when it rains and the rainwater is absorbed by the impregnated sheet, the liquid fertilizer impregnated here will dissolve and be absorbed in the ground, acting as a fertilizer with immediate effect, The liquid fertilizer containing the complex microorganisms can promote the growth and prevent the occurrence of disease damage.

The liquid fertilizer impregnated in the impregnated sheet acts effectively as a fast-acting fertilizer for several months, but after that, solid fertilizer is gradually melted and absorbed into the ground, and as a persistent fertilizer. Can promote the growth of seedlings.
Also, since the impregnated sheet is made of vegetable fiber or paper, it will compost after several years and its shape will collapse, but during this time, because it covers the slope, weeds do not propagate and protect the seedlings, It is possible to prevent the topsoil on the slope from being washed away by rain.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. 1 to 4 show a method for producing the fertilizer-containing mat 1. First, as shown in FIG. 1, the solid fertilizer 3 is bonded onto the impregnated sheet 2. The impregnated sheet 2 is formed of a woven or non-woven fabric of plant fibers such as hemp and cotton, or paper, and is impregnated with liquid fertilizer. As the liquid fertilizer, for example, a liquid microorganism mixed with a photosynthetic bacterium, a yeast, an actinomycete, a lactic acid bacterium, or a complex microorganism, and sugar, minerals, nitrogen, etc. is used and impregnated with hemp, cotton, paper, or the like. It is dried. As the solid fertilizer 3, pellets, granules, or powders obtained by mixing microorganisms with nitrogen, phosphoric acid, potassium, etc. are used.

Applying an adhesive on the surface of the impregnated sheet 2,
The solid fertilizer 3 is sprinkled thinly and uniformly here and adhered as shown in FIG. In this case, starch glue is used as the adhesive. Then, as shown in FIG. 2, the impregnation sheet 2 is overlaid on the solid fertilizer 3. After that, it is passed through a crimping device (not shown) and the impregnated sheet 2 on the upper surface and the impregnated sheet 2 on the bottom are overlapped at a predetermined interval as shown in FIG. As shown in FIG. 4, as a whole, the fertilizer-containing mat 1 having a thickness of about 5 mm is manufactured by crimping in a quilted shape.

The fertilizer-containing mat 1 thus produced is laid on the slope 5 as shown in FIG. 5, and the fertilizer-containing mat 1 is cut into X-shapes at intervals of planting seedlings 6, and the cut portion 7 is opened. Then, the slope 5 is exposed, a hole is dug in the slope 5, and a seedling 6 is planted as shown in FIG. As the seedlings 6, for example, birch, shii, camphor trees, etc. are planted. In this case, the solid fertilizer 3 is held in the space between the two upper and lower impregnation sheets 2 and 2 which are pressure-bonded in a quilted manner, and is further adhered to the impregnation sheet 2 with an adhesive. The solid fertilizer 3 inside moves and can be held in a mat shape without being biased during transportation or installation.

When left in this state, when it rains and rainwater is absorbed by the impregnated sheet 2, the liquid fertilizer impregnated therein is dissolved and absorbed into the ground, and as a fertilizer with immediate effect. Acts on seedling 6. In this case, since the liquid fertilizer contains complex microorganisms such as photosynthetic bacteria, yeasts, actinomycetes, and lactic acid bacteria, the microorganisms are absorbed into the ground to promote the growth of the seedlings 6 and prevent the occurrence of disease damage. Can be prevented. In addition, the impregnated sheet 2 made of hemp, cotton, or paper of the fertilizer-containing mat 1 serves as a residence of microorganisms and can further promote the reproduction of microorganisms.

The liquid fertilizer impregnated in the impregnated sheet 2 works effectively for 1 to 2 months, but thereafter, the solid fertilizer 3 is gradually melted and absorbed into the ground, and the seedling is used as a sustainable fertilizer. 6 can be promoted. It takes about 6 to 12 months until the solid fertilizer 3 is completely melted, and during this period, the fertilizer component of the seedling 6 is continuously supplied,
Microorganisms propagate in the ground to promote growth.

Further, the impregnated sheets 2, 2 of the fertilizer-containing mat 1
Is made of plant fibers such as hemp and cotton, and paper, so it takes about 3 years until it composts and loses its shape. During this period, weeds do not propagate because they cover slope 5. The seedling 6 can be protected and the topsoil on the slope 5 can be prevented from being washed away by rain. Moreover, the composted impregnated sheet 2 serves as a fertilizer for the seedlings 6 to further promote the growth, and even at this time, the seedlings 6 are firmly rooted and grown even if weeds grow, and the roots are deeply rooted. The surface 5 can be firmly held.

In the above embodiment, the case where the seedlings 6 are planted on the slope 5 is shown, but the present invention can be applied to the case where the trees are planted along the road or on the green belt of the factory. Further, the present invention is not limited to the case where the seedling 6 is planted, but the solid fertilizer 3
By using the fertilizer-containing mat 1 in which grass seeds and the like are mixed, it is possible to promote the germination and growth of seeds while preventing the growth of weeds just by laying it on the ground.

[0015]

As described above, according to the fertilizer-containing mat of the present invention, the ground is exposed even if the mat is laid on a slope or a green belt and a sapling is planted there and then left alone. Weeds are suppressed from growing, and immediate-acting and persistent fertilizers are exuded over a long period of time to continuously supply fertilizers to the seedlings, and after the seedlings have grown several years later. The mat itself can be composted. Therefore, unlike the conventional method, it is not necessary to lay straw or Como on a steep slope and to appropriately spread fertilizer, and it is easy to lay and can be left as it is after planting, which is excellent in workability. In addition, the fertilizer-containing mat in which solid fertilizer is mixed with seeds can grow lawns and the like simply by laying the mat.
