Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can-growing nursery pot and a plant transplantation method for growing plants with the nursery pot buried in the soil of a field.

[0002]

2. Description of the Related Art In planting cultivation, plants such as shrubs and middle trees are grown either directly in the open ground or in nursery pots. When transplanting plants planted in the open field for shipping as commodities, dig the surroundings with the roots left, excavating them with soil attached to the roots. Then, put straw on the soil so that the soil does not separate from the root, wrap a rope over it, transport it to the destination with the root wound, remove the rope and straw, and remove it with the soil on the root. And re-plant.

In the case of such open-field planting, irrigation and fertilization can be performed all at once, so that it can be relatively easily cared for. However, as described in JP-B-53-24330, they are grown in nursery pots. In some cases, irrigation and fertilization are cumbersome, require careful management, and are inefficient. In addition, when plants are large, it is often difficult to grow them in nursery pots.

[0004] Therefore, when the plants are planted in the open field and grown to a state where they can be shipped, the soil around the roots is dug, excavated with the soil attached to the roots, wound with straw as described above, and shipped and transplanted. There are many.

However, when digging around the soil with soil attached to the roots, roots are cut off, and thick roots and new roots at the end are also cut off and remain in the open ground, so that the growth power is weak and the growth after transplantation is poor. . Therefore, the burden on the plant is reduced by removing the branches and fruits according to the growth power of the plant, but it cannot satisfy the demands of customers who want to grow with the fruits. There is.

Further, at the time of transplantation, it is necessary to dig around the root while cutting a thick root extended far, and it is also troublesome to wrap the straw and tighten it with a rope, which requires a great deal of labor. .

On the other hand, as described in JP-A-3-15320, a container formed by laminating a plastic film having a plurality of holes on the outer surface of a nonwoven fabric and forming a bag-like container is placed in a normal field soil. It is proposed to embed and raise the seedlings in this container.

[0008]

However, when planting at the transplant site, the container having a laminated structure is removed. However, since many roots are entangled with the nonwoven fabric or entered into each hole of the plastic film, the container is removed. It is difficult to remove and the work load increases.

[0009] The technical problem of the present invention is to focus on such a problem, and to reduce the labor required for transplanting with the soil attached to the root after raising and growing the seedling in the soil of the field. is there.

[0010]

The technical problem of the present invention is solved by the following means. A first aspect of the present invention is a can-growing seedling pot in which a plurality of slits and other holes through which thin roots of a plant can pass are formed on at least one of a side wall and a bottom wall of a can made of metal or synthetic resin.

As described above, since a plurality of holes such as slits through which the fine roots of the plant can pass are formed in the side wall and the bottom wall of the can, when this can-growing seedling pot is buried in the open field and the plant is grown, Since the roots of the plant pass through the hole and extend into the soil of the field, irrigation and fertilization are sufficient in the same manner as in open-field cultivation.

[0012] When transplanting, the soil outside the can-made nursery pot can be dug, and the entire can-made nursery pot can be dug and transported to the destination, so that the conventional end-roll which requires labor is not required. Also, when the roots that have passed through the hole become thicker than the size of the hole, they are cut off by the hole and die, so when digging a can-grown seedling pot, it is sufficient to cut only the thin root that has not been cut off by the hole, Digging from the open field is easier.

In addition, many thick and thin roots remain in the can-growing seedling pots, and the cut thin roots start growing immediately after transplantation, and therefore have a strong growth power. In this way, since harvesting is possible, there is no need to drop fruits and branches as in the past, transplantation can be performed with fruits and branches attached, and customers are pleased.

At the time of transplanting, the can-growing seedling pot is removed,
In the case of the dismantling type, if the can is made of metal, the connecting portion between the slits and holes is rusted and the strength is reduced, so that the can is easily dismantled by cutting the connecting portion. In the case of a synthetic resin, the connecting portion can be easily cut and dismantled and removed. In this manner, since the dismantling is performed at the time of transplantation, the used empty cans can be effectively used, and the cost can be reduced.

As shown in FIG. 5, if a taper is provided, the roots and soil of the plant can be separated from the nursery pot without being dismantled, so that the cost can be reduced by repeatedly using the nursery pot.

A second aspect of the present invention is a dismantling type can-growing seedling pot,
2. A can-growing seedling pot in which the holes according to claim 1 are slits, are formed in a large number in a desired direction, and are left only between adjacent slits to such an extent that they can be easily separated later. .

As described above, since a plurality of slits are formed in a desired direction and a connecting portion between the slits is cut,
It is sufficient to cut only the connection part having a short dimension, and the operation of dismantling the can-made nursery pot at the time of transplantation becomes easy.

A third aspect of the present invention is a can-growing pot having a plurality of slits or other holes formed on at least one of a side wall and a bottom wall of a can made of metal, synthetic resin, or the like. A can-growing seedling pot in which a plant is planted in the can-growing seedling pot in a state where the plant is buried in the soil of the field while leaving all or the upper end.

As described above, plants are planted in the can-growing pots in a state where the can-growing pots formed with a plurality of holes such as slits are buried in the open ground, leaving all or the upper end thereof. Therefore, thin roots extend into the soil of the field through holes such as slits. As a result, it grows with simple care, similar to open field planting.

When the roots that have passed through the slits and the like become thick, they are naturally cut by the holes such as the slits, and only the thin roots pass through the slits. In addition, at the planting site, after the can-made nursery pot is dismantled or separated so that it can be reused,
Thick and thin roots remain along with the soil, and since they are well rooted, new thin roots are immediately extended after transplantation, so that growth after transplantation does not decrease.

When the seedling pots are buried in the open ground, if the whole of the pots is not buried and the upper end is left slightly, water and fertilizer may be removed when the pots are irrigated or fertilized. Flowing out can be suppressed.

According to a fourth aspect of the present invention, there is provided a can-growing seedling pot comprising a plurality of slits or other holes formed on at least one of a side wall and a bottom wall of a can made of metal, synthetic resin, or the like. In the state where all or the upper end is buried in the soil, plants are grown in the can-made nursery pots, and when transplanting the plants in the can-made nursery pots, the cans are dug out together with the can-made nursery pots. This is a plant transplantation method characterized by removing a nursery pot and then re-planting it with soil attached to a root.

As described above, the can-growing pots with slits and the like are buried in the open field to cultivate the plants, and when transplanting, the can-growing pots are dug out of the open-field and are transferred to the transplant site with the can-growing pots attached. Since the plants are transported, the nursery pots are removed, and the plants are replanted, there is no need to cut the thick roots of the plants as in the related art, and the operation is free from the work of wrapping straws and ropes. Since only the roots extending out of the slits are cut, the rooting is sufficient and the transplantation can be carried out with nuts and branches attached without any decrease in growth power.

[0024]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment will be described as to how a canned nursery pot and a method for transplanting a plant according to the present invention are actually embodied.

There are two types of canned nursery pots of the present invention: dismantling type and reusable type. FIG. 1 is a perspective view showing one embodiment of a dismantling type can-made nursery pot according to the present invention. Reference numeral 1 denotes a can, which may be made of metal or synthetic resin, and the material is not particularly limited. Large can be used from drums and small cans can be used, and the size is not particularly limited. It is preferable to use used empty cans from the viewpoint of effective use of resources.

The can 1 is provided with a slit 3a in the vertical direction and a slit 3b in the horizontal direction on the side wall 2 thereof. A slit 5 is also formed in the bottom wall 4. Between the slits 3a, 3b, 5 so as not to communicate with each other,
They are connected at the connection part 7.

That is, both ends of each of the slits 3a, 3b, 5 are not communicated with the other slits, and a part is connected to the connecting portion 7a.
Has been left as. Thus, the plurality of slits 3a,
If 3b and 5 are left open, it is sufficient to cut only the connecting portion 7 between the slits, so that disassembly becomes easy. Therefore, the connecting portion 7 is left only in a small size that can be easily separated later.

The width of these slits is set so that the thin roots of the plants planted in the can can pass through. That is, the slit width is set according to the diameter of the root that allows passage from each slit to the outside. For example, about 5 mm in width and 5 to 30 in length
cm, but is not limited to this dimension.

In the illustrated example, the slits 3a, 3b on the side walls are shown.
Are oriented in the vertical direction and the horizontal direction, but may be in an oblique direction or the like, and may be slits of other shapes such as a circular shape or a mesh shape instead of a linear shape. The slits 5 in the bottom wall 4 are also parallel to each other, but need not be parallel.
Slits of any shape are possible.

It is preferable that the slit is formed in both the side wall 2 and the bottom wall 4, but it is also possible to form the slit in only one of them.

FIG. 2 is a longitudinal sectional view showing the use state of the can-growing nursery pot 1 of FIG. In the nursery pot 1 made of cans, high-quality improved soil 8 is put, and seedlings 9 are planted. Then, the nursery pot 1 made of cans is buried in the field 10.

At this time, it is possible to completely embed the whole of the nursery pot 1 made of cans in the field 10, but leave the upper end of the can on the ground without embedding, for example, about 2 to 3 cm like h. If it keeps, it can prevent that fertilizer and water in the can nursery pot 1 flow out and are wasted.

As described above, since the canned nursery pot 1 has the slits 3a, 3b and 5 open, the slits 3a,
3b, the soil 8 in the canned nursery pot 1 and the soil 1 in the field via 5 and 5
0 is integrally continuous. Therefore, the root 11 of the plant 9 in the can-growing nursery pot 1 extends to the field 10 through the slits 3a, 3b and 5, and grows by absorbing the nutrition of the field 10. Therefore, care such as irrigation is sufficient in the same manner as in open-field cultivation, and management becomes easy.

FIG. 3 is an enlarged view of the portion A in FIG. 2 and shows the process of root growth. The root of the plant in the can passes through the slit 3b of the can side wall and extends into the soil 10 of the field, but grows smoothly while the root 11a is thinner than the slit width as in the upper slit 3b. To go.

On the other hand, when the root 11b grows up to the width of the slit 3b like the slit 3b on the lower side, the slit portion cannot be thicker than the slit width, and eventually cut off at the slit portion and withers.

Then, in order to maintain life, new roots are generated in the can-growing pot 1, and the plants 9 in the can-growing pot 1 are repeatedly extended by passing through other positions of the slit. grow up. Therefore, the plant 9 is always in a sufficiently rooted state in the can-made nursery pot 1.

As described above, since there is no root thicker than the slit outside the can-made nursery pot 1, it is necessary to dig the soil around the can-made nursery pot 1 at the time of transplantation to excavate the can-made nursery pot 1. Easy to do. That is, it is free from the work of cutting a thick root as in the related art. Further, in the state excavated from the field 10, the root 11 and the improved soil 8 of the plant still remain in the can-growing seedling pot 1, so that there is no need to use a straw or a rope as in the related art. It can be transported to the transplant site as it is.

At the transplant site, each slit 3a, 3a in FIG.
When the connecting portion 7 between b and 5 is cut off by cutting scissors or the like,
Since the slits 3a, 3b, and 5 are separated from each other, they can be easily disassembled.

After dismantling, the soil in the can-growing nursery pot 1 remains attached to the plant as it is, so that the plant is sufficiently rooted. Therefore, the growth power does not decrease after transplantation, and transplantation can be performed with fruits and branches attached, and there is no need to cut off flowers, fruits and branches as in the conventional case. In other words, regardless of the weather or the season, the tree can be grown as it is without damaging the tree.

In the embodiment shown in FIGS. 1 to 3, slits 3a, 3b and 5 are formed in the can-growing seedling pot 1, but as shown in FIG. 6
May be opened. These holes 6 may be made independent for each hole. However, as shown in FIG. 4, if the portions other than the connecting portion 7 are continuous, only the connecting portion 7 may be cut off during disassembly, and a slit is provided. As in the case of disassembly, disassembly becomes easy.

FIG. 5 is a perspective view showing another embodiment of a can-made nursery pot according to the present invention, that is, a reuse type.
(1) is a slit type, and (2) is a porous type.
In this embodiment, the nursery pot is used repeatedly without dismantling. For this reason, the intervals between the slits 12 in the slit type shown in FIG. 1A are sufficiently large to maintain the strength. In the case of the porous type as shown in FIG. 2B, the structure is such that the holes 13 are not continuous and are not too close.

Furthermore, in order to use repeatedly without being dismantled, it is tapered so that plants and soil in the seedling pots 14a and 14b can be easily taken out of the seedling pots at the time of transplantation. That is, the tapered seedling pots 14a, 1
After digging around 4b and excavating the tapered seedling pots 14a and 14b from the field, with the thin roots coming out of the slits 12 and the holes 13 cut off, pull up or invert the plants inside. The plants with soil on the roots and the tapered seedling pots 14a and 14b can be easily separated.

Accordingly, the tapered seedling pots 14a, 14a
b can be used repeatedly many times without dismantling. Since it is used repeatedly in this manner, the intervals between the slits 12 and the holes 1
The interval 3 is set to such an extent that the strength does not decrease.
Also, a shape without any irregularities is suitable so that the soil and plants inside can be easily taken out, and the taper angle should be steep.

[0044]

According to the first aspect, the side wall and the bottom wall of the can are
Since multiple holes, such as slits, through which the fine roots of the plant can pass are formed, when this can-growing seedling pot is buried in the open ground and the plant is grown, the roots of the plant pass through the hole and pass through the soil in the field. Irrigation and fertilization are the same as in open-field cultivation.

In the case of transplanting, soil outside the can-made nursery pot is dug, and can be excavated together with the can-made nursery pot and transported to the destination. Also, if the roots that have passed through the hole become thicker than the hole size, they will be cut off by the hole and die, so when digging a can-made nursery pot, it is sufficient to cut only the thin roots that were not cut off by the hole. The work of excavating from the open field becomes easier.

In addition, many thick and thin roots are left in the seedling pot made of cans, and the cut thin roots start growing immediately after transplantation, so that they have strong growth power. In this way, since harvesting is possible, there is no need to drop fruits and branches as in the past, transplantation can be performed with fruits and branches attached, and customers are pleased.

When transplanting, the nursery pot made of can is removed,
In the case of the dismantling type, if the can is made of metal, the connecting portion between the slits and the holes is rusted and the strength is reduced. Therefore, the can can be easily disassembled by cutting the connecting portion. In the case of a synthetic resin, the connecting portion can be easily cut and dismantled and removed. In this manner, since the dismantling is performed at the time of transplantation, the used empty cans can be effectively used, and the cost can be reduced.

As shown in FIG. 5, if a taper is formed, the roots and the soil of the plant can be separated from the nursery pot without being dismantled, so that the cost can be reduced by repeatedly using the nursery pot.

According to the second aspect of the present invention, since a plurality of slits are formed in a desired direction and a connecting portion between the slits is cut, it is sufficient to cut only a short connecting portion. The task of dismantling and removing is easier.

According to the third aspect of the present invention, a plant is planted in a can-growing pot having a plurality of holes, such as slits, buried in the open ground while leaving all or the upper end thereof open. Therefore, thin roots extend into the soil of the field through holes such as slits. As a result, it grows with simple care, similar to open field planting.

When the root that has passed through the slit or the like becomes fat, it is cut naturally by the hole of the slit or the like, and only the thin root remains after passing through the slit. Become easier, and at the planting site,
After dismantling and removing canned seedling pots and separating them for re-use, thick and thin roots remain with the soil and are well rooted. So that growth after transplantation does not decrease.

When the nursery pot made of can is buried in the open ground, if the whole is not buried and the upper end is left slightly, water or fertilizer may be exposed when the nursery pot is irrigated or fertilized. Flowing out can be suppressed.

According to the fourth aspect of the present invention, plants are grown by burying canned seedling pots having slits or the like in the open ground, and when transplanting, the canned nursery pots are dug out of the open ground and transplanted with the canned seedling pots attached. Since they are transported to the site, the can-made nursery pots are removed, and the plants are re-planted, it is not necessary to cut the thick roots of the plants as in the related art, and the operation is free from the root winding work of winding straw or rope. Since only the roots extending out of the slits are cut, the rooting is sufficient and the transplantation can be carried out with nuts and branches attached without any decrease in growth power.
