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 a moderate air permeability so that the root can be wound. The present invention relates to a method for producing a cultivation container, in which each seedling can be grown uniformly by suppressing the phenomenon, and each pot can be easily separated to improve transplantation efficiency.

[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 the above circumstances, and has as its object to eliminate the need for inserting a pot into a tray for raising seedlings, to appropriately maintain drainage and water retention, and to prevent root rot. It is unlikely to occur, the air permeability can be kept moderate, the root wrapping phenomenon can be suppressed, each seedling can be grown uniformly, and each pot can be easily separated to improve transplantation efficiency,
It is intended to provide a method for producing a 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.

[0007] According to the method for producing a cultivation container of the present invention, a bottomed storage pot opened at each of a plurality of openings of the same diameter opened at regular intervals in the vertical and horizontal directions or at regular intervals in the vertical and horizontal directions. In addition, instead of inserting single pots one by one, a plurality of pots can be inserted at the same time, and the cultivation container can be provided that can save labor for mounting work.

After the seedlings are raised, the upper opening edges of the pots are partially connected to each other so that the pots can be easily separated from each other. Therefore, the present invention can be provided as a cultivation container capable of improving the workability of transplanting seedlings and the like.

In particular, according to the fourth aspect of the present invention, a plurality of pots are connected, and these pots do not rotate in the circumferential direction, and can be fixed in a state where the drilled positions of the corner holes are respectively positioned. That is, if a plurality of corner holes are pre-drilled at positions not overlapping with the legs, in addition to the above-described effects, a gap formed between the storage pocket and the pot body is formed. In addition, water leached from the pot, sprinkled water, and the like can be efficiently removed without pooling.

FIG. 4 is a partial perspective view schematically showing a cultivation container 10 according to a first embodiment of the present invention, and FIG.
6 is a sectional view taken along line BB of FIG. 4.

In the figure, a cultivation container 10 manufactured by the manufacturing method of the first embodiment has a part thereof in a state where the upper opening edge 1 of the pot 5 is arranged vertically and horizontally along one plane. It is heat-fused, connected and connected, and integrally formed, so that one pot body 5 can be inserted into each of a plurality of storage portions (opening 21 or storage pot 34) formed in the cultivation tray. It is arranged in.

The pot body 5 has a cylindrical side wall 2 ending at an opening edge 1 on an end side, and a bottom wall 3 continuous with an axial lower end of the side wall 2, and has a rectangular cross section. The four corner holes 4 are formed in a cross shape. However,
The shape of the cross section of the pot body 5 is not limited, and may be rectangular, circular, or other shapes. 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 at 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 the enlarged perspective view of the main part in FIG. 7, when the whole shape is opened in a semi-oval shape, the water moving downward along the inner surface of the side wall 2 is efficiently drained. Because it is possible, it is desirable.

Each of the pots constituting 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. Opening, the upper end opening edge 1 of the side wall 2 is arranged so as to be planar along one plane, and a part of the opening edge 1 of the pot body 5 adjacent to each other is integrally formed by heat fusion, respectively. This is preferable because existing equipment can be used as it is without forming a new mold and can be formed extremely easily, and cost can be reduced.

Further, as shown in FIG. 8, a double-walled body formed by blow molding is cut into a double-walled body 5, 5 in a state where a central portion thereof is cut and 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 one pot 5 can be held in each opening 21. 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, 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 in order to increase the supply of oxygen, and it is not necessary to ventilate the water. No winding phenomenon occurs. 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 carrying out so-called transplanting for extracting the seedlings from the pots 5 and replanting them, or for so-called pot-lifting work for 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 cultivation container according to the invention of claim 4.

The cultivation container according to the present invention is not limited to the cultivation containers described in the above-mentioned embodiments, and can be appropriately modified and implemented without departing from the gist 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 manufactured by the manufacturing method of the present invention, for example, the opening edge of the upper end of the side wall of the pot body formed into an appropriate cross section by blow molding is arranged in a plane along one plane. Since it is configured so that a part of the opening edge of each of the pots adjacent to each other is fused and integrally formed vertically and horizontally, the following particularly remarkable effects and effects which are not seen in the conventional cultivation container are provided. Is 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 to each other and can be easily separated, workability such as transplantation 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, and drainage and air permeability can be appropriately maintained. In addition, the air circulation to the roots of the seedlings is good, and the roots are tightly packed during the 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 in the cultivated soil and the root winding phenomenon does not occur. That is,
Ideal seedlings with good root growth and elongation to the deep layer can be raised, and their survival 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 one seedling by hand with each cell still connected. 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) In addition, the soil attached around the roots does not collapse when the seedlings are taken out.
The whole seedling including the root can be taken out without damage. That is, it is unlikely that the roots are damaged during these operations 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-described effects, water leached from the pot or water sprinkled from the pot into the gap formed between the leg and the pot. Since it can be removed without being accumulated, it is possible to obtain a function and effect that mold is hardly formed at this position and root rot is hardly caused.

Therefore, the cultivation container of the present invention according to each claim can be said to be extremely effective.
