Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for producing bags, saplings and saplings for planting and saplings.

[0002]

2. Description of the Related Art In a general planting place where a hole can be easily dug, a hole is dug in the ground, and a seedling or a soil improvement material is carried in and applied, and then a seedling is planted. Further, after irrigation to prevent drying, mulching is performed using plywood, cardboard, vinyl sheet, or the like.

On cut slopes or concrete sprayed slopes where it is difficult or impossible to dig a hole in the ground, a knitting fence or concrete pocket is provided to cover soil, sandbags, nonwoven bags, etc. Vegetable bags filled with soil are installed on the glue frame, and the soil is sprayed over the entire surface.

[0004]

In a method of providing a knitting fence, a concrete pocket, or the like on a cut slope or a concrete spray slope, etc., a sufficient amount of cultivation is ensured due to topographical conditions and the like. It is difficult and economically burdensome. Similarly, the method of spraying the soil after the seedlings have been installed is difficult to spray the soil to a thickness sufficient for the growth of the plant for economic reasons and the like. Vegetation bags in which sandbags or non-woven bags are filled with soil are inexpensive, but tend to dry out of the bag surface and cause seedlings to die.

[0005] In addition, short plants such as seedlings are subjected to pressure by weeds unless mulching is performed, and are likely to cause remarkable poor growth. In addition, it is inevitable to dig the seedlings produced from the nursery and remove them from the cultivation containers, and these operations tend to hurt the seedlings and take time.

An object of the present invention is to provide a method for producing bags, saplings and saplings for planting and seedling production, which prevents evaporation of water during cultivation and has excellent water absorbing ability.

[0007]

SUMMARY OF THE INVENTION A first type of planting and seedling production bag according to the present invention has a separate impermeable sheet portion. Each of the other water-impermeable sheet portions is integrated with one peripheral portion covering the other peripheral portion except for a filling port for the soil. The one impermeable sheet portion has a cut which is used for the root and for drainage. A water gap is provided between the two peripheral portions.

The second type of planting and sapling bag also has a separate impermeable sheet portion. Each of the other water-impermeable sheet portions is integrated with one peripheral portion covering the other peripheral portion except for a filling port for the soil. The one impermeable sheet portion has a root-permeable sheet portion at the center. A water gap is provided between the two peripheral portions.

A third type of planting and seedling production bag has an impermeable sheet portion and a root-permeable sheet portion. The water-impermeable sheet portion and the root-permeable sheet portion are integrated at the periphery of both, leaving a filling port for the soil. The water-impermeable sheet portion includes a covering portion whose peripheral portion extends outward.

A bag seedling according to the present invention uses a bag for planting and seedling production of the third type. The planting and seedling production bags are filled with the soil through the filling port, and the filling port is closed. The root portion of the seedling is buried in the soil by passing through the impermeable sheet portion, and the bud portion is exposed to the outside.

[0011] The method for producing sacks according to the present invention uses a third type of sacks for planting and producing saplings. Plant the seedlings in the bag.
The covering portion of the bag is moved to the water-impermeable sheet portion side, and the water-impermeable sheet portion is placed on the upper surface and arranged side by side in a semi-standing state. Then, the upper irrigation is absorbed by the soil through the root-permeable sheet portion.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION In the case of the first type of planting and seedling production bag according to the present invention, each of the water-impermeable sheet portions is
One peripheral part covers the other peripheral part except for the filling port of the cultivation soil, and is integrated.

The shape of the bag is not particularly limited.
Oval and polygonal shapes can be used, but squares and rectangles are preferred in terms of handling. As the impermeable sheet portion, for example, a polyethylene sheet, a vinyl sheet, or an aluminum wheel can be adopted.

The filling port is for filling the cultivation soil, and if the opening area is too small, it is difficult to fill the bag with the cultivation soil.
It is preferable that the opening area be at least enough to allow the hand shovel to enter and exit.

In the case where the two impermeable sheets are made of a heat fusible material such as a polyethylene sheet or a vinyl sheet, fusion is preferred, but sewing or bonding may be used. When the portion is made of a non-fusible material such as an aluminum wheel, it is formed by sewing or bonding through an adhesive. Of course, in addition to these, appropriate integrated means such as clipping and tacking can be employed.

The peripheral portion to be integrated may be a two-ply portion of one peripheral portion and the other peripheral portion of the water-impermeable sheet portion, or a three-ply portion having one peripheral portion sandwiching the other peripheral portion. It may be a part. In the case of two sheets, the inner volume of the bag is large, but the integration work is slightly troublesome. In the case of three sheets, the capacity of the bag is small, but the integration operation is simple.

[0017] The one impermeable sheet portion has a cut for drainage and drainage. These cuts for permeable roots and drainage are for allowing the root system to protrude to the outside of the impermeable sheet part as the seedlings grow, and for absorbing water when the root system protrudes outside. It also functions as a passage for drainage. The length of this cut should be such that the inside soil does not leak out. The appropriate length is 1-4cm,
Preferably it is 2 cm. Further, the arrangement is suitably such that 3 to 5 pieces are arranged in one row vertically at equal intervals and 1 to 3 rows horizontally, preferably two rows of four pieces. Of course, a staggered arrangement or a random arrangement can also be employed. Further, the shape can be appropriately selected from a state of being cut open by a blade, a slit shape, an elliptical shape and the like. It is more preferable to insert a corrosive sheet such as newsprint or kraft paper so that the soil does not leak from this cut.

A water gap is provided between the peripheral portions. The water gap is formed by providing a non-integrated portion in the integrated portion. That is, in the case of fusion or sewing, a portion that is not fused or sewn may be provided on the processing line. In the case of sewing, if the seam is coarse, the gap between the seams can be a water gap. Therefore, it is not necessary to prepare a portion that is not stitched, but it may be prepared just in case.

When the first type of planting and seedling production bags is used, the following procedure is used. First, the bag is filled with soil and sealed, and a part of the water-impermeable sheet portion on the surface of the bag is cut open or the root system of the seedling is passed through a slit formed in advance, and embedded in the soil. As a result, the central portion of the bag is raised, and a portion having a surrounding water gap is located at a lower position. Thus, the bag in which the seedlings are planted is placed on the planting surface. The planting surface may be a horizontal surface or an inclined surface.

When there is water spray or rainfall, water droplets hit the other surface, ie, the upper surface of the impermeable sheet portion, flow along the slope, and penetrate into the inner soil through the surrounding water gap. As the root system develops, its tip protrudes into the soil on the planting surface outside the bag through one of the impermeable sheet cuts on the lower surface. This break is also useful for draining when the amount of water that has accumulated on the planting surface has penetrated into the soil in the bag or when the amount of water that has permeated through the water gap has been too large.

When the planting surface is an inclined surface, it is difficult for water droplets to penetrate the soil through the water gap located above the planting and seedling production bags in the inclination direction, but to penetrate through the water gap at other locations. .

In the case of the second type of planting and seedling production bag according to the present invention, the difference between the first type of planting and seedling production bag is that one of the impermeable sheets is located at the center. By having the root-permeable sheet portion, other configurations and methods of use are the same as those of the first planting and seedling production bag. Therefore, the description will be limited to the root-permeable sheet portion, and the other portions will be omitted.

The root-permeable sheet portion only needs to be able to allow the root system to protrude from the inside of the bag through the sheet portion and to prevent the soil in the bag from leaking to the outside. The nature of the root-permeable sheet doubles as drainage of surplus water. Therefore, a porous substance, for example, an open-cell sponge, a nonwoven fabric, or a net is used for the root-permeable sheet portion. The location of the root-permeable sheet is preferably substantially at the center of the bottom surface of the bag,
The ratio of the area to the bottom surface is about 20 to 70%, preferably 40%. Of course, a root-permeable sheet portion having an area smaller than that of the root-permeable sheet portion disposed at one place may be scattered on the bottom surface. Further, it is more preferable to use a biodegradable non-woven fabric for the root-permeable sheet because the root will become corroded when the root becomes thicker in the future.

The bags for planting and seedling production of the second type are placed so that the root-permeable sheet faces the planting surface. In the event of watering or rainfall, part of the water flowing down the planting surface is absorbed by the soil through the root-permeable sheet. As the seedling grows, its roots protrude out of the bag through the permeable sheet and invade under the planting surface and develop.

A third type of planting and seedling production bag has an impermeable sheet portion and a root-permeable sheet portion. The water-impermeable sheet portion and the root-permeable sheet portion are integrated at the periphery of the both except for the filling port for the soil. The peripheral portion of the water-impermeable sheet portion extends outside the root-permeable sheet portion to form a covering portion.

The soil for filling the planting and seedling production bags is filled through the filling port, and both sheets are integrated to close the filling port. The method of integration is the same as the previously described method. The impermeable sheet portion is cut open or a seedling is inserted through a slit provided in advance, the root portion of the seedling is buried in the cultivation soil, and the bud portion of the seedling is exposed to the outside. This covering portion covers the periphery of the installation surface of the bag in actual use, suppresses the evaporation of water from that portion, and prevents the generation of weeds in that portion.

The bag seedling according to the present invention uses the third type of planting and seedling production bags described above. The planting and seedling production bags are filled with soil. The cultivated soil contains a chemical fertilizer and an organic soil amendment necessary for the growth of seedlings as usual. The roots of the seedlings are buried in the soil, and the buds are extended to the outside of the impermeable sheet. A slit may be provided in advance at a portion where the seedling is exposed to the outside of the water-impermeable sheet portion, or the portion may be cut out with a knife.

Since seedlings have already been planted in the bag for planting and seedling production, they are transported to the planting site as they are, and the section of the section without the overlapping portion is placed facing the planting surface. Just
Planting on the planting surface becomes possible. Since the seedlings can be placed on the site after they have sufficiently settled, the seedlings rarely die. In addition, the action as a bag for planting and seedling production is [0025]
And [0026] are substantially the same as those described for the third bag for planting and seedling production, and a description thereof will be omitted.

The method for producing sacks according to the present invention uses a third type of sacks for planting and producing saplings. The planting and seedling production bags are filled with soil through the filling port, and both sheets are integrated to close the filling port. The method of integration is the same as the previously described method. The impermeable sheet portion is cut open or a seedling is inserted through a slit provided in advance, the root portion of the seedling is buried in the cultivation soil, and the bud portion of the seedling is exposed to the outside. The covering portion of the bag in which the seedlings are planted is moved to the water-impermeable sheet portion side. That is, it is folded, rounded, or folded. Then, the water-impermeable sheet portions are arranged side by side in an upright state and in a semi-erected state. Appropriate support is applied to both ends of the lined planting and seedling production bags so that they do not fall.

When water is irrigated from the upper part of the planting and seedling production bag, water flows down the upper surface of the water-impermeable sheet portion, partly flows into the bag through the gap from which the seedlings protrude, and partly flows into the bag. The planting and seedling production bag penetrates through the root-permeable sheet portion of the neighboring planting and seedling production bag that is in contact with the water-impermeable sheet portion.

According to this method, cultivation can be carried out densely, so that the occupied area of cultivation is reduced, the size occupied in the vertical direction of the cultivated soil becomes large, and the direct roots grow long. Since the root system grows through the root-permeable sheet part, it is easy to take root on the planting surface.Moreover, since this root system is prevented from penetrating into the adjacent planting and sapling production bags by the water-impermeable sheet, the bags are connected to each other. Do not stick.

[0032]

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings, identical reference numbers indicate identical or corresponding parts. 1 to 3 show a specific example of a first type planting and seedling production bag 1a of the present invention, which is rectangular.

Reference numeral 2a denotes the other impermeable sheet made of polyethylene. 3a is one impermeable sheet part, also made of polyethylene. These water-impermeable sheet portions 2a and 3a are sewn in a state where the filling port 4 of the soil is left and the peripheral portion 3b of the water-impermeable sheet portion 3a covers the peripheral portion 2b of the water-impermeable sheet portion 2a. I have.

The impermeable sheet portion 3a has a cut 3c for the root and the drainage. And both peripheral parts 2b and 3b
A water gap 5 is provided between them. This water gap 5 appears by not meeting that part.

A bag 1 for planting and producing seedlings of this first type
If a is used, proceed as follows. The cultivation soil is filled from the filling port 4 into the planting and seedling production bag 1a. The portion of the filling port 4 is folded back onto the upper surface of the water-impermeable sheet portion 2a to meet. If the water gap 5 is also formed in the meeting part, water can be effectively absorbed.

The impermeable sheet portion 2 on the surface of the completed bag
A part of “a” is cut open, passed through the root system of the seedling, and embedded in the soil. Place the bag with the seedlings on the planting surface.

When there is water spray or rainfall, water droplets hit the surface of the water-impermeable sheet portion 2a and flow along the slope of the water-impervious sheet portion 2a. When the root system develops, its tip protrudes into the soil on the planting surface outside the bag through the cut 3c of the impermeable sheet portion 3a. The cut 3c is useful for allowing the water droplets accumulated on the planting surface to permeate into the soil in the bag and for discharging excess water inside the bag.

When the planting surface is an inclined surface, water drops hardly permeate into the soil through the water gap 5 located above the bag in the inclination direction, but penetrate through the water gap 5 at other locations.

4 and 5 show a specific example of a second type of planting and seedling production bag 1b according to the present invention. The difference from the first planting and seedling production bag 1a is that one of the water-impermeable sheet portions 3a has a root-permeable sheet portion 6 'at the center and has no cut 3c. The method of use is the same as that of the first bag for planting and seedling production 1a. Accordingly, the description will be limited to the root-permeable sheet portion 6 ', and the other portions will be omitted.

The root-permeable sheet portion 6 'only needs to be able to allow the root system to protrude from inside the bag through the root-permeable sheet portion 6' and to prevent the soil in the bag from leaking to the outside. . Therefore, a porous substance, for example, an open-cell sponge, a nonwoven fabric, or a net is used for the root-permeable sheet portion 6 '. The position of the root-permeable sheet portion 6 'is preferably substantially at the center of the bottom surface of the bag.

A bag 1 for planting and producing seedlings of this second type
b is placed so that the root-permeable sheet portion 6 'faces the planting surface. When watering and rain flow down the planting surface,
A part thereof is absorbed by the soil through the root-permeable sheet portion 6 '. As the seedlings grow, their roots protrude out of the bag through the root-permeable sheet portion 6 'and penetrate below the planting surface and develop. Excess water in the bag flows out through the root-permeable sheet portion 6 '.

FIGS. 6 and 7 show a third type of planting and seedling production bag 1c according to the present invention. The third type of planting and seedling production bag 1c is a water-impermeable sheet portion 2
a and the root-permeable sheet portion 6.

The water-impermeable sheet portion 2a and the root-permeable sheet portion 6
Are integrated at their peripheral portions 2b and 6 except for the filling port 4 for the soil. The impermeable sheet portion 2a has a covering portion 2c in which a peripheral portion 2b extends outward.

When used, the soil is filled from the filling port 4, and the impermeable sheet portion 2a and the root-permeable sheet portion 6 are integrated to close the filling port 4. The water-impermeable sheet portion 2a is cut open with a knife, and the seedling is planted in the soil. Instead of cutting with a blade, a cut may be provided in advance.

Then, the bag into which the seedlings are implanted is placed on a planting surface such as a cut slope or an embankment slope with the root-permeable sheet portion 6 facing down. The covering part 2c is extended so as to cover the periphery of the installation surface of the bag. Sprinkling water and rainwater that have fallen on the planting surface flow down on the surface, penetrate from the root-permeable sheet portion 6 into the bag, and are absorbed by the soil. The covering portion 2c suppresses the evaporation of moisture from the surrounding surface and also prevents the generation of weeds in that portion.

FIG. 8 shows a specific example of the bag seedling 7 according to the present invention in a half-cut state. This bag seedling 7 uses the third type of planting and seedling production bag 1c described above.
Therefore, description of the bag 1c for planting and seedling production is omitted.

The soil 1 is filled in the bag 1c for planting and seedling production. The cultivated soil 8 is mixed with a chemical fertilizer and an organic soil improving material necessary for the growth of the seedling 9 as usual. The seedling 9 has its root 9 'buried in the soil 8 and its bud 9 "extends outside the impermeable sheet 2a. The place where the seedling 9 goes outside the impermeable sheet 2a May be cut open with a blade or a cut may be provided in advance.

FIG. 9 shows an example of planting with the bag seedling 7. Since the seedling 9 has already been planted in the bag seedling 7, the seedling 9 is carried to the planting slope 10 as it is, and the root-permeable sheet portion 2 b is placed on the planting face 1
0, and the surrounding planting surface is covered with the covering portion 2c.

In this case, planting of the planting surface is possible only by placing the bag seedling 7 toward the planting surface 10. Seedling 9
Since it can be put on the site after it has been fully established, it is unlikely to die.

FIG. 10 shows a specific example of the method for producing the saplings 7 according to the present invention. In this manufacturing method, a third type of planting and seedling production bag 1c is used. Bag 1 for planting and seedling production
The configuration and operation of c have been described in [0042] and [0043], and will not be described.

Also, the seedling 9 is placed in the bag 1c for planting and seedling production.
Is also the same as described in [0044], and a description thereof will be omitted. The covering portion 2c of the bag in which the seedlings 9 are planted is rounded toward the impermeable sheet portion 2a. When the bag has a rectangular or rectangular shape, the bag may be one of the two pairs of facing portions 2c.
Then, the water-impermeable sheet portions 2a are arranged side by side in an upright state and in a semi-standing state. Appropriate supports 11a and 11b are applied to both ends so that the lined bags do not fall.

Watering is performed from above the bag in which the seedlings are planted. The water flows down the upper surface of the water-impermeable sheet portion 2a, a part of the water flows into the bag through the gap from which the seedlings 9 protrude, and a part of the root permeability of an adjacent bag in contact with the water-impermeable sheet portion 2a. Seat part 6
To penetrate the soil 8 in the next bag.

According to this method, cultivation can be carried out densely, so that the occupied area for cultivation is reduced. In addition, the size occupied in the up and down direction of the cultivation soil 8 becomes large and the direct roots grow long, so that a strong seedling with a high trunk can be obtained. Since the root system grows to the outside through the root permeable sheet part 6, it is easy to take root on the planting surface. In addition, this root system prevents the infiltration into the adjacent bags from the impermeable sheet portion 2a.
, So that the bags do not stick together.

[0054]

According to the first type of planting and seedling production bags of the present invention, each of the different water-impermeable sheet portions leaves a filling port for cultivation soil, and one peripheral portion is the other peripheral portion. Since the soil is integrated in a covered state, when the soil is filled, the water contained in the soil does not evaporate to the outside and retains water for a long time, which is convenient for the growth of seedlings. The shape of the bag is not particularly limited.

Further, since one of the water-impermeable sheet portions is provided with a cut for root penetration, after filling the soil into the bag from the filling port, the filling port portion is placed on the upper surface of one of the water-impermeable sheet portions. By folding back and integrating with one of the impermeable sheets, the filling port can be easily closed, and as the seedlings grow, the root system projects outward through the cut in the impermeable sheet and the seedlings This break is good, and this break is that the amount of water droplets accumulated on the planting surface penetrates into the soil in the bag,
It is also useful for draining excess water inside. In addition, since a water gap is provided between the two peripheral portions, water droplets of water sprinkling and rainfall can be taken into the inside soil, and death due to drying can be prevented.

According to the second type of planting and seedling production bag according to the present invention, the first type of planting and seedling production bag is provided with a root-permeable sheet portion in place of a cut-through for a root. Therefore, the root system can protrude from the bag through the root-permeable sheet portion to the outside, and the soil in the bag can be prevented from leaking to the outside. Other effects are the same as the first planting and seedling production bags.

According to the third type of planting and seedling production bag according to the present invention, the water-impermeable sheet portion and the root-permeable sheet portion are integrated at the periphery of the both except for the filling port for the soil. Since the water-impermeable sheet portion is provided with a coating portion extending outward on the periphery, the bag is filled with cultivation soil and seedlings are planted. Rainwater that flows down can be absorbed into the soil through the root-permeable sheet, and the covering covers the surrounding area of the bag, preventing evaporation of water from that part and preventing weeds from forming in that part. it can.

The bag seedling according to the present invention uses a third type of planting and seedling production bag, and the planting and seedling production bag is filled with cultivated soil, and the root portion of the seedling is buried in the cultivated soil. Since the buds were extended to the outside of the water-impermeable sheet portion, they were transported to the planting place as they were, and the root-permeable sheet portion was simply placed on the slope to be planted. The seedlings can be placed on the site after the seedlings have sufficiently settled, so that the seedlings rarely die.

According to the method for producing a bag seedling according to the present invention, a bag of the third type of planting and seedling production of the present invention is used as a bag, the seedling is planted in the bag, and the water-impermeable sheet portion is placed on the upper surface. In order to irrigate from the top, the irrigation water flowing down the upper surface of the water-impermeable sheet portion of the bag is passed through the root-permeable sheet portion of another bag that is next to and in contact with the cultivation. The root system that can be absorbed and exits through the root-permeable sheet part of one bag can be prevented from entering the next bag by the water-impermeable sheet part, so that the bags are stuck together by the root system. There is no.
