TECHNICAL FIELD The present invention relates to a pot used for container cultivation of plants, especially trees.

[0002]

2. Description of the Related Art Container cultivation of trees has recently attracted attention as one of the techniques for growing and cultivating seedlings for the purpose of greening parks and residential environments. Container cultivation is done by planting seedlings in pots and growing them.When it is time to transplant by shaping the tree shape during this time, plant them in pots and move them to the surroundings of parks and houses, plazas and roads. The pot is planted in the pot for ornamental use, or after growing, the pot is removed and transplanted to the open field. The most important feature of this cultivation method is that it eliminates the need for root cutting and root-wrapping work, which was necessary for open-field planting, so that the work can be simplified and speeded up without the need for skilled engineers. There is a great advantage that the transfer can be performed by mechanical work. In addition, since this container cultivation does not require root cutting, it is possible to move in the summer, which was generally avoided in the past, and it is not restricted by the season, and it is possible to transplant it without exposing the tree shape to the extreme. There are various advantages and features in comparison.

In this container cultivation, the pot is used together with the tree from the stage of growing the tree until it becomes a mature tree, and further until it is placed in a park or plaza for ornamental use. It is provided in the form. In particular, the size of the pot is selected depending on the tree species, and it is removed when it is transplanted to the open field, or it is buried in the soil and is not exposed, but it is placed in a park, plaza, or room. In addition to being considered as an ornamental object along with trees, consideration is given to design such as shape, and various materials are also taken into consideration.

As described above, various kinds of pots for container cultivation are used under the conditions of use, but this cultivation method is cultivated and moved in one pot from seedling to mature tree. In the past, the root and the peripheral wall are the same except for the drainage holes provided in the bottom so that roots do not grow outside the pot or dry around the root during the growing period for several years during this period. It is usually watertight.

[0005]

Therefore, in the case of container cultivation, when transplanting a tree into the soil, it is necessary to remove or destroy the pot. There was no. Therefore, when transplanting a small number of trees, the work is not so much, but it is a heavy burden when transplanting a large number of trees to form a hedge or a roadside tree. The work was extremely troublesome when the trees were large and the pots were large accordingly.

The present invention has been researched and developed in view of such circumstances, and when a tree grown in container cultivation is transplanted into the soil, the pot used during cultivation is buried in the soil that encloses the root soil. In addition, the present invention aims to provide an improved pot for new container cultivation that does not adversely affect the growth of trees thereafter. More specifically, according to the present invention, while growing a tree, the roots that extend are stopped in the pot to suppress the outward extension, and the moisture in the pot is suppressed to prevent drying around the roots. At the time of transplanting, it is embedded in the soil of the pot, the roots can be freely extended after transplanting, and it can be integrated with the planting soil. It is easy to handle and can be transplanted efficiently for container cultivation. It is intended to provide the pot of.

[0007]

The present invention has been made for the above-mentioned object, and its main feature is that it is a combination of two inner and outer containers. And as for the outer container, it suppresses the overhanging of the roots during the growing of the tree, arranges the tree shape, and makes it convenient for transporting the tree,
Regarding the inner container, when transplanting the tree into the soil, it can be removed from the outer container integrated with the root and root soil and embedded in the soil, and the transplant can be completed, and it will grow after transplanting. The roots can be freely extended out through the inner container so that they can be integrated into the soil. By combining these two containers, tree growth, transplantation, and subsequent growth can be performed consistently. It is intended to provide pots for container cultivation.

The present invention will be described in more detail. The features of the present invention are an outer container having an upper opening.
The outer container has an inner container that is freely inserted and removed through the opening of the outer container, and the outer surface of the peripheral wall is in contact with the inner surface of the peripheral wall of the outer container.The outer container has a drain hole at the bottom. Another object of the present invention is to provide a container cultivation pot in which a plurality of through holes penetrating the inside and the outside are formed in a dispersed manner in the inner container over substantially the entire surface of the peripheral wall portion.

Further, according to the present invention, the peripheral wall portions of the inner and outer containers to be fitted together are formed in a taper shape in which the diameter gradually increases toward the upper opening, so that the fitting combination of the inner container with respect to the outer container and the withdrawal can be facilitated. The purpose is to provide the pot for container cultivation.

The present invention also provides an obstacle for preventing the root of a tree from coming off on the inner surface of the peripheral wall of the inner container so that the soil attached to the root of the tree and the inner container are integrated with each other. It is to provide a pot for container cultivation in which the inner container can be reliably and easily removed from the outer container.

In the above case, it is desirable that the obstacle protrusion is provided in the middle of the height near the upper opening,
Further, in order to integrate with the root and evenly entangle and stabilize with the whole soil around the root, it is desirable to provide it so as to project annularly on the inner surface of the peripheral wall portion of the inner container.

The present invention also provides the above-mentioned cultivation pot,
It is intended to provide a pot for container cultivation in which a hanging handle is provided on the upper part of the inner container. This hanging handle is used when pulling out the inner container from the outer container, and is also used as a pillar during growing and curing of trees. The shape of this hanging handle is not limited to one, but it is formed in the shape of a gate using a metal wire rod, and the two of them are made to face the opening of the inner container, and the lower ends of each are pivotally attached freely. When pulling out and inserting the inner container, both upper ends should be aligned to form a grip, which should be opened outside when planting seedlings or when caring for the trees so as not to hinder the work.

The hanging handle is formed in a gate shape.
Face each other, pivot the lower end of the inner container to the edge of the upper opening of the inner container, and bend the upper ends of both handles outward to bend the supporting recess. When forming and raising or curing a tree, it is advisable to raise each of the supporting hands so that the supporting recesses are attached to the trunk of the tree and tied up, whereby a stable supporting post can be obtained.

Further, the present invention provides a pot for container cultivation in which the inner container has a through hole penetrating in the peripheral wall portion in the horizontal direction, and the fall prevention rod can be freely inserted and removed into the hole. To provide. At the time of transplantation, the above-mentioned fall prevention rod penetrates the inner container in a skewered shape and is embedded in the soil together with the inner container, and stabilizes the inner container by overhanging horizontally in the soil, and protects the tree from wind and the like.

BEST MODE FOR CARRYING OUT THE INVENTION Next, a container cultivation pot according to the present invention will be specifically described according to the illustrated embodiment, the features thereof will be clarified, and other features will be also described. FIG. 1 is a front view of the pot of the present invention in which two inner and outer containers 1 and 2 are fitted to each other and are ready for use. FIG. 2 is a plan view of the inner container 2 taken out from the outer container 1 and arranged side by side. FIGS. 3A and 3B are front views of the central longitudinal section in a state where the inner container 2 is pulled up and separated from the outer container 1.

The outer container 1 shown in this embodiment is formed in a rectangular box shape having an inverted trapezoidal shape, and the peripheral wall portion 3 is formed in a taper shape in which the diameter gradually increases toward the upper opening portion 4, and the bottom portion 5 is formed. A drain hole 6 is formed in the center of the. This outer container 1 needs to have required durability and weather resistance so that it can be stably used throughout the growing period of trees, but the material may be wood, synthetic resin, or metal material. It may be. In particular, for the purpose of growing trees outdoors, it is appropriate to use a concrete product having a required weight in order to prevent falling by wind and enhance weather resistance.

On the other hand, since the inner container 2 is fitted into the outer container 1 so as to be integrated, the outer container 1 has an outer shape adapted to the inner shape of the outer container 1. Therefore, here, as shown in the figure, the outer container 1 is formed into a box shape having an inverted trapezoidal shape, and is formed into a box shape having an inverted trapezoidal shape which is substantially similar to that of the outer container 1. Taper shape that gradually expands.

As will be described later, this inner container 2 is fitted into the outer container 1 for protection when growing a tree, while at the stage of transplanting the tree into the soil, the inner container 2 is embedded in the soil together with the tree to be integrated. The durability and weather resistance required for the container 1 are not required. For this reason, the material is not particularly selected, but it is convenient to use, for example, a wooden container that is naturally destroyed by being subjected to secular change after being buried in the soil or corroded depending on the tree to be grown.

In this inner container 2, a large number of through holes 9 are formed in a tapered shape in the peripheral wall portion 7 over substantially the entire surface, and the inner wall of the peripheral wall portion has a height close to the opening portion 8. An obstacle protrusion 10 is provided on the way, and a drain hole 12 is formed in the center of the bottom portion 11 so as to communicate with the drain hole 6.

The through hole 9 serves as an opening for the root of the tree after the tree is transplanted into the soil. In this embodiment, the four wall surfaces constituting the peripheral wall portion 7 are formed so that the root can grow naturally. It has been set up so that it is evenly distributed over the entire surface.
Further, here, a large number of large and small are mixed and formed. Although the through hole 9 is circular here, it is not specified to this shape, and the number and size are not specified, but it is preferably wide and large from the viewpoint of root growth. It is desired to be one. However, the strength of the inner container is required not to be impaired because it needs to be self-supporting and portable after being taken out from the outer container.

The obstacle projection 10 is for preventing the root of the tree and the clod attached to it from coming out together with the inner container 2, and has a shape that protrudes inward from the inner surface of the peripheral wall portion and bites into the clod. Anything will do. Therefore, it may be a protrusion or a shelf. In this embodiment, it is formed into a rectangular ring by projecting from the four corner inner surfaces of the peripheral wall portion 7 in a shelf shape, and the lower part thereof receives the earth mass that solidifies with the root so as not to slip out.

A bottom portion 11 of the inner container 2 is provided in a raised bottom shape at a position elevated from the lower end of the peripheral wall portion to form a vacant chamber 13 thereunder, and two of the four surfaces of the peripheral wall portion 7 surrounding the vacant chamber are opposed to each other.
Insertion holes 14a and 14b are provided facing each other between the surfaces. The insertion holes 14a and 14b are provided with a fall prevention rod 15,
16 is inserted in a skewered shape to prevent the inner container 2 from tipping over, and in this embodiment, the inner container 2 is opened in the central portion of each facing surface. Then, one insertion hole 14a is opened at a position close to the lower surface of the bottom portion 11, and the other insertion hole 14b is opened at a position at a height obtained by subtracting the plate thickness of the prevention rod 15 so that the insertion holes 14a, 14a face each other. One of the fall prevention rods 15 is penetrated between them, and another fall prevention rod 1 is inserted between the other insertion holes 14b, 14b.
The two prevention rods 15 and 16 can be assembled in a crossed manner by inserting 6 through them.

In the figure, 17 is a hanging handle for the inner container 2.
This hanging handle is used when the inner container 2 is taken in and out of the outer container 1, or when it is transported, and here, it is formed so that it can be used as a support of a tree. In this embodiment, the lower ends of the two handles formed by bending the metal wire into a gate shape are bent outward, and the axial ends provided thereby are formed near the opening 8 of the inner container. It is provided so as to be inserted into a shaft hole (not shown), pivotally attached so as to be freely rotatable, and to be laterally opposed to each other.

The hanging handle 17 swings to the left and right with the lower end fitted in the shaft hole as a fulcrum, and the swinging free end is used as a handle, and the portion of the handle is curved outward to support recesses. 18 to be attached to a tree as described later.

The pot according to the present invention is constructed as described above, and when used, the inner container 2 is housed in the outer container 1 and the peripheral wall portions 3 and 7 are doubled. In this state, the seedling 19 is placed in the inner container 2.
Are planted and filled with soil 20 to be used for growing. In the drawing, it is shown as a tree in a state in which it has grown to a level suitable for transplanting. However, the hanging handle 17 is raised with respect to the seedling 19 immediately after planting, and its supporting recesses 18, 18 are added,
By appropriately binding with a string or the like, this will be used as a support.

The pot of the present invention is used for container cultivation as described above, and various cultivation conditions may be changed depending on the kind of the seedling 19, but the inner and outer containers 1 and 2 are fitted during the growing. It will be used occasionally, and water and fertilizer will be applied during this period. The roots 19a of the sapling will greatly extend as the seedling grows, but at this growing time, the through holes 9 provided in the inner container 2 are blocked by the peripheral wall portion 3 of the outer container 1, so It stops and grows inside it (Fig. 4).

Thus, the seedlings are grown in a container fitted inside and outside until they grow to a predetermined size, during which the seedlings are mainly supported by the outer container 1 and managed in a stable state. And when transplanted, the grown seedling 1
The inner container 2 in which 9 is planted is pulled out from the outer container 1, and the inner container 2 together with the roots 19a of the seedling and the soil 20 is transported from the cultivation place to the transplanting place for transplanting.

The transplanting is performed while the inner container 2 is attached to the seedlings. In this transplant, a hole to be planted together with the inner container 2 is dug in the ground, and the inner container is embedded so that the transplant is performed. In this transplantation, the inner container 2 may be embedded as it is. However, for example, when the ground is soft or the tree height is high and the wind is likely to affect the inner container 2, the inner container 2 may fall as described above. The fall prevention rods 15 and 16 are inserted into the insertion holes 14a and 14b so as to project in the radial direction, and are buried in the soil in this state.

FIGS. 5 and 6 show a state in which the transplantation is completed after the fall prevention rods 15 and 16 are inserted. Since the prevention rods 15 and 16 project in four directions at the bottom of the inner container 2, the inner container 2 is stable and the fall of trees is prevented. In order to stabilize the tree during the period of curing at the time of completion of transplantation, the hanging handle 17 may be continuously used as a pillar.

The tree thus transplanted grows with the roots housed in the inner container 2. The roots 19a that grow along with this will extend through the through holes 9 formed in the peripheral wall portion 7 into the soil and take root. In addition, the inner container may rot in the soil or may be destroyed by root growth. Preferably, when it is destroyed after the curing period after transplantation, it does not hinder the growth of trees, which is convenient.

Although the present invention has been described with reference to the illustrated embodiment, the outer container 1 and the inner container 2 are not limited to the rectangular box shape. For example, it may be needle-like with a truncated cone shape,
The cross-sectional shape may be circular or polygonal. In short, what is required is that it fits tightly when the inner and outer containers 1 and 2 are fitted together, and that no unnecessary space is created between the two containers. That is, if a gap is formed between the inner and outer peripheral wall portions 3 and 7 when they are fitted together, the root reaching the through hole 9 during growth extends to the outside of the inner container through this through hole, so it is desired to be blocked.

In the embodiment, the inner rod 2 is provided with a protection rod 15,
Although the insertion holes 14a and 14b for inserting 16 are provided at the lower end portion of the peripheral wall portion 7 by penetrating the space 13 below the bottom portion 11 formed in the raised bottom, this is for facilitating the insertion work of the prevention rods 15 and 16. Depending on the case, it may be provided above the position of the bottom part 11 so as to penetrate horizontally through the soil 20, or by providing a ring on the outer side surface of the peripheral wall part 7 and inserting it to horizontally support the fall prevention rod. You may do it.

Further, as described above, the fall prevention rod 15,
Reference numeral 16 does not need to be a strip plate as shown in the drawing, but may be a round bar shape or a square bar as it supports the fall of trees in the soil when burying the inner container 2 in the soil. Good. Further, in the embodiment, the two fall prevention rods 15 and 16 are inserted in an intersecting manner, but one may be inserted or a plurality of them may be inserted in other directions. Of course, these prevention rods are not necessary until the inner container 2 is buried in the soil, and it is needless to say that they need to be removable when the inner container 2 is a separate body.

[0034]

The present invention is constructed and used as described above, and while the seedling is being grown, the inner and outer containers 1 and 2 are fitted and doubled to close the through hole 9 opened in the inner container 2. The outer container 1 is made to have an external appearance by preventing the roots from overhanging when used. Therefore, the pot of the present invention has the appearance of the outer container 1 during the growth of seedlings, and can be used as a normal pot. On the other hand, at the time of transplantation, the inner container 2 together with the sapling is extracted from the outer container 1 and embedded in the soil together with the inner container, so that the work can be performed much more easily than the conventional transplantation. Become.

In particular, according to the present invention, since the transplantation can be performed together with the inner container, the root cutting work performed at the time of transplantation becomes unnecessary and the root winding work becomes unnecessary.
Therefore, even an amateur can easily perform the transplanting work without requiring skill. Moreover, according to the pot of the present invention, the root cutting work is unnecessary, and since the soil attached to the root remains in the inner container 2, there is no fear of landing at the time of transplantation, which makes it unsuitable for transplantation work. It has the advantage of being able to work even during the summer months and greatly reducing transplant failures. Of course, there is no problem of landing since root cutting can be omitted and rooting can be done without sticking, so the tree shape can be adjusted during cultivation, and it is effective that the tree immediately after transplanting is in an unnatural state. It can be avoided.

On the other hand, in the pot of the present invention, the root can be projected in the soil through the through hole 9 to secure the rooting, while the root soil and the inner container 2 integrally support the root, so that the root is firmly held in the soil. It can be planted, the use of the pillar on the ground can be omitted, and if further support is needed, the underground support can be provided by inserting the fall prevention rods 15 and 16 into the inner container and assembling. Moreover, there is an advantage that stable planting is possible. It goes without saying that the pot of the present invention can be used as a container in a park, plaza or indoors and can be used for ornamental viewing of trees since it can be used as a single container.
