Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention eliminates the need to insert a pot into a nursery tray, keeps drainage and water retention at an appropriate level, hardly causes root rot, and keeps air permeability at an appropriate level to prevent root wrapping. The present invention relates to a cultivation container that can suppress the phenomenon and allow each seedling to grow uniformly, and can easily separate each pot and improve the efficiency of transplantation.

[0002]

2. Description of the Related Art Conventionally, when raising vegetable seedlings or flowering tree seedlings, plastic seedling cell trays or seedling pots made of plastic such as polyethylene or vinyl have been frequently used. Further, openings or storage pockets are provided in a row in the horizontal and vertical directions, and a single pot is inserted into each of the openings or storage pockets.

[0003]

However, according to the conventional cultivation trays, it is necessary to insert pots one by one into openings or storage pockets formed in the cultivation trays, which is troublesome. The work efficiency is extremely poor, and when performing planting or potting work, the upper end of the pot must be picked out one by one and taken out, so that the work is troublesome and complicated.

In addition, water leached from the pot or water sprinkled from the pot accumulates in a gap formed between the legs constituting the storage pocket and the pot, so that mold or root rot is generated at this position. There is a problem that the root easily causes a turning phenomenon (called a circle phenomenon or a looping phenomenon) in the pot.

The present invention has been devised in view of such circumstances, and a problem to be solved is to solve the above-mentioned problems and problems of the conventional cultivation container.

[0006]

The gist of the means adopted by the present invention to solve the above-mentioned problems is as described in the above-mentioned claims.

According to the cultivation container of the present invention employing such a configuration, the cultivation container is provided at each of a plurality of openings having the same diameter opened at regular intervals in the vertical and horizontal directions, or at regular intervals in the vertical and horizontal directions. Instead of inserting single pots one by one into the bottom storage pot, a plurality of pots can be inserted at the same time, and the work of attaching the pots can be saved.

During the raising of seedlings, a plurality of corner holes are formed at the corners of each pot, so that drainage and water retention can be maintained at an appropriate level and air permeability can be maintained at an appropriate level.

After raising the seedlings, the upper opening edges of the pots are partially connected and the pots can be easily separated from each other, so that the operability of transplanting seedlings and the like can be improved.

[0010] In particular, according to the cultivation container of the invention according to claim 4, a plurality of pots are connected, and these pots do not rotate in the circumferential direction, and the positions where the corner holes are formed are positioned. Can be fixed to That is, since a plurality of corner holes are formed in advance at positions that do not overlap with the legs, in addition to the above-described effects, a gap formed between the storage pocket and the bowl is formed. In addition, water leached from the pot, sprinkled water, and the like can be efficiently removed without pooling.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in more detail with reference to more specific examples shown in the drawings.
This is a typical example, and the present invention is not limited by the following examples unless the gist is exceeded.

By the way, typical cultivation trays to which the cultivation container of the present invention is applied include those shown in schematic perspective views in FIGS. Cultivation tray 2 shown in FIG.
No. 0 is characterized in that it has a plurality of openings 21 of the same diameter which are opened at regular intervals in the vertical and horizontal directions. The cultivation tray 30 shown in FIG. 2 has openings 31 of the same diameter at regular intervals in the vertical and horizontal directions, and a plurality of legs 32 are vertically provided below each opening 31 so that lower ends of the legs 32 are formed. Is formed on the bottom plate 33 to form a storage pot 34 with a bottom. However, the dimensions, shape, number, and the like of the openings 21 and the storage pots 34 having the same diameter are matters that can be appropriately changed in design.

The cultivation container of the present invention can be used in a cultivation tray (cage tray) 40 as shown in FIG.

The material for producing the cultivation container of the present invention is not particularly limited. However, from the viewpoint of ease of molding and cost, polystyrene (PS), polyethylene (PE), polypropylene (PP), etc. It is preferably a synthetic resin, and is preferably a biodegradable material from the viewpoint of preventing environmental pollution.

FIG. 4 is a partial perspective view schematically showing the cultivation container 10 of the first embodiment according to the present invention. FIG. 5 is a sectional view taken along line AA of FIG. 4, and FIG. It is B sectional drawing.

In the figure, the cultivation container 10 of the first embodiment is shown.
Is formed by integrally connecting a part of the upper end opening edge 1 of the pot body 5 by heat-sealing and connecting them integrally in a state of being arranged vertically and horizontally along one plane. Each of the plurality of storage portions (the opening 21 or the storage pot 34) is provided such that the pots 5 can be inserted one by one.

The pot body 5 has a cylindrical side wall 2 ending at an opening edge 1 on the end side, and a bottom wall 3 continuous with the axial lower end side of the side wall 2 and has a rectangular cross section. And 4
The corner holes 4 are formed in a cross shape. However, pot 5
The shape of the cross section is not limited, and may be a rectangle, a circle, or another shape. The dimensions and the like are items that are appropriately designed and changed based on the dimensions and the shape of the cultivation tray to be applied.

The corner hole 4 is a through hole formed in the corner from the bottom wall 3 to the side wall 2, and has both functions as a drain hole and a ventilation hole. The corner holes 4 may be opened after connecting the plurality of pots 5, but from the viewpoint of workability, the corner holes 4 should be opened in each of the pots 5 before connection. Is preferred. However, the size and shape of the corner holes 4 are not limited. The width dimension does not need to be the same over the entire length, but if the width dimension of the corner hole 4 is too wide, it is necessary to provide, for example, a mesh body or the like, because the soil buried in the pot body 5 leaks. However, since it is very troublesome, it is preferable to make the hole so narrow that the cultivation soil does not flow out.

As shown in an enlarged perspective view of a main part in FIG. 7, the whole shape is a semi-oval shape, and
It is preferable to form a corner hole so as to be provided above the wall, because water that travels downward along the inner surface of the side wall 2 can be drained efficiently.

These cultivation containers may be molded by sheet molding or injection molding, but a plurality of corner holes 4 are formed in the corners of the blow molded pot 5 and the upper end of the side wall 2 is formed. When the opening edges 1 are arranged so as to be planar along one plane, and a part of the opening edges 1 of the pots 5 adjacent to each other are respectively heat-sealed and integrally formed, a new mold is created. It is preferable because existing equipment can be used as it is and can be formed extremely easily, and cost can be reduced.

Further, as shown in FIG. 8, the central portion of the blow-molded two-piece body is cut off to form a two-piece pot body 5, 5 in a state where a part thereof is connected. If the corner holes 4 are opened at the corners of 5, and heat-sealed, the labor for the connection work can be saved.

Next, the cultivation tray 20 shown in FIG.
Next, a method of growing a plant by applying the cultivation container 10 of the embodiment will be described together with its operation and effect.

The cultivation tray 20 has a configuration in which six openings 21 are formed in the horizontal direction and four openings 21 in the vertical direction (a total of 24), and each of the openings 21 can hold one pot 5 one by one. It was done. The cultivation container 10 of the embodiment has 6
In this case, four (in total, 24) pots 5 in the vertical direction are arranged at positions corresponding to the 24 openings 21 opened in the cultivation tray 20. Therefore, if the cultivation tray 20 is provided so as to cover the cultivation container 10, it is needless to explain again that the pots 5 can be inserted one by one into each of the 24 openings 21. That is, instead of inserting single pots into the opening 21 one by one as in the related art, the pots can be inserted at the same time, and the setting effect can be obtained quickly and reliably. Can be

Then, seedlings or seedlings are planted by putting soil into each of the pots, and fertilized if necessary, and then raised with appropriate watering. Since four corner holes 4 are respectively formed at the corners of the pots 5, a function as a drainage hole (drainage hole) is exhibited, so that appropriate drainage and appropriate water retention can be maintained. In addition, it can function as an air vent to maintain optimum air permeability and promote root development. In other words, it is not necessary to reduce the moisture to increase the supply of oxygen and to ventilate, and the root of the seedling extends to the pot wall in search of oxygen due to lack of oxygen during the cultivation, and a so-called root winding phenomenon occurs. Never wake up. That is, it is possible to obtain an effect that the watering work, the water retention management, and the ventilation management can be performed extremely easily and efficiently, and the optimum growth environment of the plant can be maintained.

Next, when performing the so-called transplanting of extracting the seedlings from the pots 5 and replanting them, or the so-called pot-raising operation of replanting the extracted seedlings into a larger pot, the pots are extremely easily removed. Since the work can be taken out as an independent pot and the operation of removing the root winding part at the time of planting or transplanting as in the related art is not required, the work efficiency is improved.

In the cultivation tray 20, for example, four cultivation containers in which three pots are connected in a horizontal direction and two pots in a vertical direction (a total of six) can be used. It can be configured to apply two cultivation containers in which three pots are connected in the direction and four pots are connected in the vertical direction (a total of 12 pots). Needless to say, it is possible to obtain substantially the same operation and effect as the operation and effect described above. Therefore, such a cultivation container is also included in the cultivation container of the present invention according to the claims.

The cultivation container 10 of the embodiment can be applied to a cultivation tray 30 as shown in FIG. 2 or a so-called basket tray 40 as shown in FIG. 3, and has substantially the same operation and effects as those described above. Is obtained.

On the other hand, as schematically shown in an enlarged perspective view of a main part in FIG. 9, since the pot 5 cannot rotate freely in the circumferential direction, the position of the corner hole 4 can be positioned and fixed. It is possible to adopt a configuration in which all the corner holes 4 are arranged in advance at positions that do not overlap with the legs 32 formed on the cultivation tray 30 of the type shown in FIG. Then, in addition to the above-described effects, water leaking from the pot or water sprinkled from the pot can be removed from the gap formed between the leg portion 32 and the pot 5 without collecting the water. The effect of preventing mold growth and root rot can be obtained. In particular, it corresponds to the embodiment of the invention according to claim 4.

The present invention is not limited to the cultivation containers described in the above embodiments, but can be implemented with appropriate design changes without departing from the spirit of the present invention.

[0030]

As described above, the cultivation container of the present invention according to the present invention has a very simple structure and can be manufactured very easily by blow molding and point fusion of plastics. It can be said that this is extremely economical in that there is no need to create a new mold.

According to the cultivation container of the present invention, for example, the upper opening edges of the side walls of the pot body formed into an appropriate cross-sectional shape by blow molding are arranged in a plane along one plane, and the pots adjacent to each other are arranged. Since the body is configured so that a part of the opening edge is fused and integrally formed in the vertical and horizontal directions, the following particularly remarkable functions and effects not found in the conventional cultivation container can be obtained.

(1) One pot is provided for a cultivation tray having a plurality of openings of the same diameter or a cultivation tray having openings and a bottomed storage pot below each opening. Since a plurality of pots can be inserted at the same time instead of being inserted one by one, the workability of inserting the pots can be improved. (2) Since the pots are partially connected and easily separated, workability such as transplanting can be improved. (3) Since a plurality of corner holes are formed at the corners of each pot, drainage and air flow can be promoted, drainage and ventilation can be appropriately maintained, and the roots of the seedlings can be maintained. The air circulation to the soil is good, and the roots are firmly packed during the soil cultivation, so that the so-called root winding phenomenon can be suppressed. (4) Since the growing point of the root abuts on the side wall of the pot and extends downward without further extending in the lateral direction, the root is tightly packed during the cultivation and the root winding phenomenon does not occur. In other words, ideal seedlings that grow well and grow deep into the roots can be raised, and the rooting after planting is good. (5) Since the pots are connected and connected as if they were temporarily fixed, they can be easily divided by hand to form a single pot. There are no operational difficulties or complications, such as picking and pulling the seedlings one by one by hand in a connected state. Therefore, the transplanting operation and the potting operation can be completed quickly and reliably, and the operation efficiency of such operation can be improved. (6) Further, during the work of taking out the seedlings, the soil attached around the roots does not collapse, and the whole seedlings including the roots can be taken out without damage. That is,
During these operations, it is unlikely that the roots are damaged and the plants die.

In particular, according to the cultivation container according to the fourth aspect of the present invention, in addition to the above-mentioned effects, water leached from the pot body or water sprinkled into the gap formed between the leg portion and the pot body. Can be eliminated without accumulating, so that the function and effect that mold grows at this position and root rot hardly occur can be obtained.

Therefore, it can be said that the cultivation container of the present invention according to the claims is extremely effective.
