[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag for root growth prevention used for tree cultivation in the open field, more specifically, it prevents evaporation of water during tree cultivation and eliminates root cutting when digging trees. The present invention also relates to a tree cultivation / delivery bag which also serves as a packaging during delivery and which does not require weeding work and topdressing work during the cultivation period.

2. Description of the Related Art In producing garden trees and vegetation trees, it is necessary to sow the soil and transplant seedlings, young trees or mature trees. In this case, the growth of cultivated trees generally grows proportionally above and below the ground. At this time, the roots in the underground part include side roots that spread around the periphery and straight roots that extend substantially vertically downward, and the thickest root is called the main root. When a tree reaches a certain size (tree type), it is shipped. At the time of shipment, work of digging out trees (generally called digging and digging) is performed.
In the case of this digging, (1) Root cutting (for transportation, the underground part must be compacted.) (2) Root winding (when root cutting, root drying and soil loss are prevented and transported. It must be easy to pack.)

At the time of this root cutting and root winding work, the most difficult thing is to cut the root under the tree. The work procedure for mining is
It looks like this: (1) Dig around the root (5 to 6 times the diameter of the tree). (2) Wrap with tsum and linen so as not to drop the soil around the roots. (3) Dig the bottom of the root. (4) Cut the straight root at the bottom of the root. (5) Lift to the ground. (6) Wrap the thigh and linen around and around the bottom root,
Tie it tight with a string. The finished product is called a root bowl. Conventionally, when digging the lower part of the root, which is the procedure of the above (3), the tree collapses or the soil of the root part collapses, the operator is pressed in the hole, leading to a fracture or death accident. There was a fear. In such conventional open field cultivation, trees are planted directly on the ground and dug at the time of shipping.

US Pat. No. 4,574,522 describes a method of planting a tree in which a bag made of a non-woven fabric is buried in the ground in advance and a tree is planted in the case of planting the tree. Bags are listed. In addition, JP-A-1-27351
No. 6, in a bag made of non-woven fabric, a guard ring effect (girdling effect) is applied to the root that penetrates the bag wall.
A root growth suppression bag adapted to exert ct) is described.

[0005]

When a bag made of the above-mentioned non-woven fabric is used, if the non-woven fabric is buried in the ground so that the non-woven fabric can be seen, evaporation of water in the soil due to capillary action of the fibers prevents the soil in the bag from drying. There is a problem that it is fast and has a high growth failure rate during planting. In addition, when a bag made of non-woven fabric is buried underground, not only does the root run on the surface of the ground, making it difficult to dig, but also the growth of the root of the surface continues, and the root becomes unattractive in the bag. Disappears. Furthermore, when topdressing is applied to the root, there is a problem that the fertilizer flows out from rainwater. Also, when using natural fibers such as hemp, during the cultivation period for several years, the fibers are corroded and the effect is not obtained, and the density of the fibers is low, and it is impossible to prevent the root growth from expanding. It was Further, when the conventional root growth suppression bag is used, since fertilizer is applied to the tree, grass grows around the root of the tree, and a great deal of labor is required for weeding.

The present invention has been made in view of the above-mentioned points, and the moisture in the soil is not exposed to the ground, the root penetrates the bag, and even if fertilizer is applied to the root, the nutrients do not flow out. Tree cultivation for root growth control, where no grass grows on the top
The purpose is to provide a shipping bag.

[0007]

In order to achieve the above-mentioned object, the bag of the present invention, as shown in the drawings,
The side surface is made of the non-woven fabric 14, and the substantially cylindrical bag body 10 having a bottom surface and the bag body 10 are connected to the upper portion of the bag body 10.
Non-water-absorbing, a circular cylindrical portion 13 Ru sheet 12 Tona having non-permeable and non-penetrating, is characterized by comprising a.
In the above bag, the upper portion of the circular cylindrical portion 13, that provide a substantially sheet 24 of lid-shaped explosion-grass desirable. The radicles inside and outside the bag that penetrate the non-woven fabric are in a state of being fastened with fibers, and growth is suppressed. The suppressed small roots in the bag branch and the number of roots increases. Suppressed radicles outside the bag cause poor growth and replenish nutrients and water from the surrounding area into the bag while keeping it thin without being enlarged. In addition, when digging up, a firmly fixed root pot with dense roots is completed in the bag, which simplifies the work and reduces the cost.

[0008] roots extending according to growth, a certain size that is through the gap of the side surface of the nonwoven fabric 14 or in forming poured, non-water-absorbing side top, having a non-permeable and non-penetrating
That sheet 12 stopped escape roots of surface portions, also prevents spills and fertilizer by rainwater, the outflow of rainwater, non-water-absorbing side upper underground portion of the sheet 12 having a non-permeable and non-penetrating non-woven fabric 14 It is possible to cut off the evaporation of water and to greatly simplify the work during digging. In addition, since the non-woven fabric 14 on the side surface functions to retain water, absorb water, and evaporate, the moisture in and out of the bag is completely transferred, and when the non-woven fabric 14 is exposed to the above-ground portion, poor growth due to insufficient water in the bag occurs. . Therefore, the upper part of the non-woven fabric is a sheet 12 having water retention, water absorption, non-water-absorption that does not evaporate, non-water permeability and non-penetrability.
A part of the sheet 12 is put in the ground to block the movement of water in the nonwoven fabric 14 so that the water is not lost. In order to utilize the nonwoven fabric having this property, too much water such as irrigation causes the water to move out, and when the water in the bag is insufficient, the water outside the bag is moved into the bag. It also has the effect of preventing soil from spilling from the net due to vibration during delivery after excavation. During cultivation, water retention on the upper side of the side, non-water-absorbing , non-water-permeable and non-penetrative
The sheet 12 having a part is left on the ground surface to prevent outflow of rainwater and outflow of fertilizer due to rainwater. Na
The bottom of the bag is non-water absorbent, non-water-permeable and non-penetrable.
It can be a sheet with, but like the side
Of course, a non-woven fabric is also possible. Further, when the weed control sheet 24 is provided on the upper part of the bag surface, weeds can be prevented from growing during cultivation. On the other hand, fertilizer is more convenient because it can be placed on the upper part of the weed control sheet 24 and fertilized by the action of the small cut 30 of the weed control sheet 24. Furthermore, it is possible to prevent the lateral transpiration of water during the dry season in summer, which is more convenient for growth. At the time of digging, even if it is dug with a machine, the soil and roots are tight inside the bag, so the root bowl will not collapse. The root pots dug out are in a packed state to be delivered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below with reference to the drawings. However, the materials, shapes, relative arrangements, and the like of the constituent members described in this embodiment are not intended to limit the scope of the present invention to them only unless otherwise specified, and simply It's just an example. As shown in FIG. 1, the bag of the present invention is formed of a substantially cylindrical bag body 10 and a non-water-absorbing , non-water-permeable and non-penetrable sheet 12 that is continuously provided on the upper portion of the bag body. consists of a circular cylindrical portion 13 Metropolitan was. Bag body 1
0 means that the side surface is made of the non-woven fabric 14 and the bottom surface is non-absorbent and non -absorbent.
The sheet 16 has water permeability and non-penetrability . The sheet 16 having a non-water-absorbing, non-water-permeable and non-penetrating property on the bottom surface requires a sheet or plate having high strength, and as an example, nylon 10 to 40 inches long and horizontal・ Synthetic yarns such as polyester and polyethylene (6
0-10 denier) or woven fabric of its composite yarn,
Laminated sheet or plastic plate laminated with film (20-100 microns) on both sides is used to prevent the weight of the tree and to prevent the tree roots from tearing when planted in a bag and to extend downward when the tree grows. Try to act as a root stop. In the former case, if it is damaged and cultivated, it will not be known until several years later when it is shipped.Therefore, even if the film is damaged, the roots that extend from the damaged part must grow by expanding the stitches of the intense woven cloth. It is not possible to do so, and growth failure occurs when the body is tightened.

The side non-woven fabric 14 is made of, for example, a high density non-woven fabric made of fibers of a synthetic resin such as polyester, polypropylene, and pre-ethylene, and preferably has a thickness of 0.1 mm to 5 mm and a tensile strength. 5 kg
In the case of needle punch processing, calender processing, and fusion fiber, a cheaper method of increasing strength by dryer processing or the like is also conceivable. . As shown in FIGS. 2 and 3, the tip of the side root (small root) 18 extending from the lower part of the trunk projects into the non-woven fabric 14 and further extends to the outside to collect water and nutrients outside the bag. However, as the root grows, if it grows above a certain level, it will be in a state of tightening the body and will not grow anymore, and it will absorb the moisture and nutrients that match the ability of the root and carry it into the bag. 20 is a cultivated tree and 22 is the ground.

[0011] The non-water-absorbing on the upper side of the bag body, non-permeable及
As the sheet 12 having non-penetrability, as an example,
High-strength 10-40 inch long / horizontal synthetic threads such as nylon, polyester, polyethylene (60-1
A laminated sheet obtained by laminating a film (20 to 100 μm) on both surfaces of a net (0 denier) (a woven fabric or a net having a strength that prevents the yarn from slipping) is used. It is preferable to use a sunlight-resistant ultraviolet ray preventing resin as this material, and to use a material that retains its strength even when exposed to long-term solar ultraviolet rays. This upper non-water absorbent, non-water-permeable and non-penetrable
Ground portion of the sheet 12 with is for preventing the prevention of outflow of fertilizer from the bag by rainwater, the runoff from the rain water bag. This non-absorbent , non- permeable and
The underground portion of the sheet 12 having non-penetrability is for the purpose of preventing laterally extending roots at the time of tree growth and preventing evaporation of water in the soil due to the capillarity of the nonwoven fabric. The sheet 12 having non -water absorption , non-water permeability and non-penetrability is
It is used to stop the packing of Nemaki at the time of shipment (stop the lid of the soil on the top of the bag).

Further, as shown in FIGS. 4 and 5, the upper portion of the circular cylinder portion 13, provided with a seat 24 for anti-grass substantially cap-like.
The circular grass-proof sheet 24 provided in the upper part of the bag is preferably made of a resin for preventing ultraviolet rays, a non-woven fabric, paper or the like, and is composed of a cut 26 and a large number of small cuts 30 in the substantially central portion, Cultivated tree 2 in cut 26 to approximately the center
Place 0 trunk on the ground. 28 is cultivated tree 20
It is a cut for passing the trunk of. It is also possible to provide a small hole instead of the small cut 30. It is also possible to use perforations instead of the breaks 26. In addition, nutrients may be applied to the weed control sheet 24 in advance. The grass 24 prevents grass from growing on the soil in the bag shielded from sunlight and eliminates weeding work, thereby enhancing the fertilizer effect. In addition, in the case of additional fertilization, fertilizer can be placed on the weed-preventing sheet 24, and the solution fertilizer that dissolves due to rain penetrates into the bag through the small cuts 30 and is absorbed by the roots, and a large number of small roots are generated to grow the tree. To do. Also, when the summer solar radiation is severe, it prevents the evaporation of water in the bag and grows more effectively. In addition, the side surface is not water-absorbent , water-permeable and
By sewn together the sheet 12 having permeability and the grass-proof sheet 24, it is possible to prevent the soil in the upper part of the bag from falling off, and to make a package that can endure the pressure when laminating the horizontal stacks.

Further, it is possible to tighten the sheet for preventing the root pot from cracking (breaking), prevent drying, sprinkle water from outside the package, and prevent stuffiness when hot and humid, which makes the work very simple and easy. There are advantages such as becoming, and non-woven fabric during delivery 1
By the action of 4, the buffering property is enhanced and the product can be safely delivered. At the time of planting, the bag may be cut with scissors or the like, and a pot filled with the completed small roots will appear, which will be planted in a predetermined place. Since the roots can be planted without roughness as in the conventional method, the water balance between the root and the leaves (when the water evaporation of the leaves is higher than the water absorption of the roots, the leaves will die and the leaves will be removed and the leaves removed) Since it is not present, you can see the beautiful tree shape during cultivation even when planting. In the above embodiment, the non-water-absorbing and non-water- passing upper part of the bag is used.
A bag is used by exposing a part of a sheet having the property of non-penetrability to the ground and burying the other part underground.

[0014]

Since the present invention is configured as described above, it has the following effects. (1) Non-water-absorbing, non-water-permeable and non -water-permeable on the upper part of the bag body.
Since the sheet having the penetrability is continuously provided, by embedding the bag so that at least a part of the sheet having the non -water-absorbing property , the non-water-permeable property and the non-penetrating property is exposed to the ground, Evaporation of water, outflow of rainwater in the bag,
It is possible to prevent the fertilizer from flowing out of the bag. Also,
Since roots do not run on the ground, digging work becomes easier. (2) When weed control sheets are provided, it is of course possible to prevent overgrowth and place additional fertilizer on the weed control sheets to use rainwater for a long time. Sometimes weed- proof sheets and non-water-absorbing, non-water-permeable top of bags
And by sewn with a sheet having non-penetration, or by fixing with a string, a stable root pot can be formed,
The soil will not be spilled even when stacked horizontally during delivery, and the root bowl will not collapse.
