DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for cultivating a plant and a method for cultivating a plant.
A plant cultivation container and a plant cultivation structure which have a simple structure and are excellent in handling properties, and which can be used as a cultivation container and also as a container for transport and sale display without having to be transplanted to another plant cultivation container. It is easy to manage, and the roots can be brought into a state suitable for growing.When planting plants in other places, complicated operations such as rooting to make it easy to take root in the soil of the planting destination are performed. The present invention relates to the provision of a plant cultivation method which does not require an operation and has an excellent survival rate after fixing.

[0002]

BACKGROUND OF THE INVENTION Conventional containers for plant cultivation include:
For example, as shown in FIG. 7, the side wall portion includes a bottom surface portion 51, a pair of side wall surfaces 52, 52 facing each other, and another pair of side wall surfaces 53, 53 facing each other. There is a known flower pot 50 having a communication part 54 provided between the two, and having a vertically long air pruning through hole 55 in the connection part 54 in a vertical line.

When this plant cultivation container 50 is used, the elongation of the root of the cultivated plant is suppressed by coming into contact with the air in the air pruning through hole 55, and the generation of roots is promoted. Further, since the communication portion 54 in which the air pruning through hole 55 is formed is set up substantially perpendicularly from the side wall surface 53, the elongation of the root is physically suppressed at the communication portion 54, and the root is removed from the container. Can be prevented from elongating along the inner periphery of the side wall of the plant, thus promoting the development of roots of the plant and preventing elongation along the inner periphery of the side wall of the root .

[0004]

However, such a conventional container for plant cultivation has a problem that its structure is too complicated to be formed of ceramics and is difficult to manufacture. To form with synthetic resin such as
There is a problem that a complicated mold must be manufactured and a large-scale apparatus is required for forming the mold.

[0005] In addition, when a plant cultivation container made of ceramic and a plant cultivation container which is a resin molded body are used to grow a seedling, it is very difficult to take out the seedling together with the soil from the container at the time of replanting. Was difficult.

Further, the strength is relatively low due to the through holes for air pruning. For example, when the plant cultivated in the container for plant cultivation is taken out of the container for plant cultivation together with the soil, the container may be damaged. There was a problem that there is.

On the other hand, cultivation of a plant without using a container for plant cultivation, that is, cultivation in which a plant is planted directly on the ground, is easier to manage than cultivation of a plant using a container for plant cultivation. When planting a plant in another place or in another container for plant cultivation, there is a problem that complicated work such as rooting for facilitating the plant to take root in the soil of the planting destination is required.

[0008] By the way, in the conventional plant cultivation container,
In particular, it is not known that a series of processes of growing tree seedlings, transporting them, and displaying them at a store can be performed in the same cultivation container.

The present invention has been devised in view of such circumstances, and a problem to be solved is to solve the above-mentioned disadvantages and problems of the conventional plant cultivation container. And the purpose is to prevent the roots from growing along the inner circumference of the plant cultivation container and promote the development of the roots, especially for growing and transporting tree seedlings. Further, a plant cultivation container having a simple structure that does not need to be planted in another container for plant cultivation, in which a series of processes up to display at a store can be performed in the same cultivation container, is provided.

Further, another object of the present invention is that the plant is easy to manage and does not need to be planted in another plant cultivation container. No need for complicated work such as rooting to make it easy to take root, and, furthermore, a plant cultivation method with an excellent rooting rate after fixation, a plant cultivation container and a plant cultivation structure that makes this plant cultivation method possible, It is intended to be provided by a simple structure.

[0011]

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

[0012] According to the plant cultivation container according to the first aspect of the present invention, the soil can be accommodated in the rolled or bent cylinder and the wall of the cylinder can be mounted on the wall of the cylinder. The convex portions and the concave portions are provided alternately, and sufficient air permeability to the soil can be secured. That is, the root of the plant that has reached this wall surface is suppressed from growing by contact with air. In addition, in this way, since the root is subjected to air pruning, root branching is induced from a portion other than the tip of the root that has been pruned, and even if the growing and growing root reaches the wall surface, the root remains inside the container body. The plant does not go around and the growth of the plant is good.

[0013] The tubular body formed inside the plant cultivation container is formed by winding or bending a flexible or flexible sheet into a roll. After cultivation until it becomes a plant, when transplanting a plant cultivated in this plant cultivation container, since the roots of the plant cultivated in the cylinder can be taken out in the state of the root mass, a large external pressure is applied. Even if the voltage is applied, the plant cultivation container itself is not easily damaged. In addition, complicated work such as rooting for making it easy to take root in the transplant destination soil is not required at all, so that the transplant workability can be improved, and the rooting rate after fixing is excellent.

The cylindrical body wound or folded in a roll can be easily opened in a sheet and reused.

Further, when transporting to another place,
When the cylindrical body in the cultivation container is opened, a gap formed between the outer surface of the root mass and the inner wall surface of the bottomed cultivation container contains water in a water retention material represented by, for example, a water-absorbing polymer. And irrigation work at the time of transportation and cultivation becomes unnecessary.

[0016] Further, while being housed in the bottomed cultivation container, a gap formed between the outer surface of the root mass and the inner wall surface of the bottomed cultivation container is filled with air-permeable soil or a material for promoting ventilation. And sufficient air permeability to the medium can be secured. In other words, when a decorative bowl for display and sale is used as a bottomed cultivation container, it is not necessary to plant the plant in the display container as in the past, and a series of processes from plant cultivation to over-the-counter display, and the subsequent process Plant cultivation can be performed in the same cultivation container.

Next, according to the plant cultivation container according to the second aspect, which adopts such a configuration, in addition to the above-mentioned action of the plant cultivation container according to the first aspect, a plurality of wall surfaces of the cylindrical body are provided. Because the through-holes are present, the roots extending up to the cylindrical body are subjected to air pruning, and root branching is induced from other than the tip of the air-pruned roots. Become.

If the cultivation is continued in the bottomed plant cultivation container, a large number of roots whose ends are enlarged are formed. Plants having roots with enlarged ends show extremely good rooting properties when transplanted to other soils.

Next, according to the method for cultivating a plant according to the third aspect of the present invention, the plant cultivation container according to the first or second aspect of the present invention obtains the above-mentioned action of the container for cultivating a plant. Cultivation can be performed, and substantially the same operation as the cultivation container according to claims 1 and 2 can be obtained.

Next, according to the plant cultivation structure according to claims 4 and 5 adopting such a configuration, the function of the plant cultivation container according to claim 1 or 2 described above is substantially equivalent to that of the container according to claim 1 or 2. Have the same effect.

[0021]

BEST MODE FOR CARRYING OUT THE INVENTION First, as a medium used for cultivating a plant using the container for cultivating a plant of the present invention, various types of conventionally known per se usually used for cultivating plants are used. And may be any of natural soil, artificial soil, or a mixture thereof. In the present invention, in particular, when a lightweight soil containing natural soil and granular or crushed resin foam is used, deformation of the plant cultivation container due to weight or the like can be prevented, and extremely favorable cultivation can be performed. In addition, it is lightweight and has excellent handleability.

The container for plant cultivation and the structure for plant cultivation according to the present invention accommodate natural soil or artificial soil, but the light-weight soil may also be used. Further, instead of the granular resin foam, other ventilation promoting materials such as mica or perlite can be used.

The natural soil is not particularly limited.
An appropriate medium can be selected and used according to the plant to be cultivated.

As the resin foam, granules of expanded polystyrene and crushed products of expanded polystyrene are particularly preferable. When a lightweight soil obtained by combining a natural soil and a granular material or a crushed material of expanded polystyrene is used, a good balance between water retention and air permeability is maintained, and plant growth is extremely good. The particle size of the granular resin foam can be appropriately determined according to the size of the plant to be cultivated, the stage of growth, and the like. In addition, a crushed product of expanded polystyrene can be easily obtained, for example, by crushing a used expanded polystyrene container, which leads to effective use of used expanded polystyrene.

The plant to be cultivated using the container for cultivating a plant of the present invention is not particularly limited, and any plant conventionally cultivated in a flowerpot or a planter can be cultivated. Especially preferred are tree seedlings or seedlings rather than plants. When a plant seedling or a seedling is cultivated by the plant cultivation method of the present invention, the transplanting operation at the time of transplantation is extremely easy, and the transplantation can be performed extremely quickly. In addition, the seedlings or the seedlings can be very well established on the transplanted soil. The structure for plant cultivation of the present invention can be cultivated for each structure for plant cultivation without transplanting seedlings or seedlings from a cultivation container for each soil.

Hereinafter, embodiments of the present invention will be described in more detail with reference to more specific examples shown in the drawings. However, these are representative examples and do not depart from the gist. It goes without saying that various design changes are possible as far as possible.

FIG. 1 is a partially cutaway perspective view schematically showing a plant cultivation container 10 according to a first embodiment of the present invention, FIG. 2 is a plan view of the plant cultivation container 10, and FIG.
FIG. FIG. 4 is a partial perspective view schematically showing a sheet 12 used to form a cylindrical body 13 provided in the plant cultivation container 10 of the first embodiment, and FIG. 5 is a cross-sectional view of the sheet 12. .

In the figure, a plant cultivation container 10 comprises a bottomed cultivation container 11 having a drainage hole 15 formed on the bottom surface, and a cylindrical body 13 formed by winding a sheet 12 in a roll shape. The convex portion 12a and the concave portion 12b are alternately formed in both the vertical and horizontal directions of the side wall of the cylindrical body 13, and the cylindrical body 13 is placed at the center of the bottom surface of the cultivation container 11, and The body 13 is filled with a medium 14 for growing a plant. In other words, the seeds of the plants sown on the medium 14 or the seedlings planted are grown so that the gap 16 is formed between the inner wall surface of the cultivation container 11 and the outer wall surface of the cylindrical body 13. Has become.

The bottomed cultivation container 11 is formed by blow-forming a synthetic resin such as polyethylene or polypropylene into a desired predetermined shape and shape. However, other known resin-forming methods such as injection molding are used. Can also be molded. In addition, in the corner part from the bottom surface of the cultivation container 11 to the side wall, a square hole or a slit-shaped small hole is generally opened.

The sheet 12 is formed by subjecting a synthetic resin sheet to vacuum sheet molding. The sheet 12 has a rectangular projection 12a having a side of 3 to 12 mm and a square having a side of 3 to 12 mm in both the front-rear direction and the left-right direction. Concave portions 12b are formed integrally with each other at equal pitch intervals, and are wound or folded in a roll shape to an arbitrary desired diameter, and the edges thereof are locked with overlapping, or a string, a thread, a wire, or the like is used. In addition to being able to be formed into a cylindrical body by being locked by, the formed cylindrical body itself has rigidity such that it can stand on its own. However, there is no limitation on the size, shape, arrangement, and the like of the protrusions 12a and the recesses 12b.
And the concave portion 12b may be connected discontinuously, or a plurality of through holes (not shown) may be formed in the entire surface of the sheet 12, and the design may be changed as appropriate.

The cylindrical body 13 is formed by winding or folding the sheet 12 in a roll shape, and is formed in a hollow shape having a circular or rectangular horizontal section with both ends opened.
By opening the winding or folding, the original sheet shape can be restored. The cylindrical body 13 may be any material that can be self-supported without peeling or being damaged even when the soil 14 for plant cultivation is filled, and may be made of a metal stylus such as a stapler by overlapping both ends. It may be joined, may be bonded with an adhesive, may be heated and welded,
Alternatively, the design can be changed as appropriate, such as by suturing with a thread or the like.

If at least the outer wall of the cultivation container 11 is colored silver or white, heat rays and the like represented by sunlight and the like can be efficiently reflected. Since the light-shielding effect can be obtained, the root growth of the cultivated plant can be improved, and the growth of the plant can be extremely improved. This is extremely suitable because it can prevent the temperature of the cultivating soil in the inside from rising and abnormal drying of the soil and can stably and favorably grow the cultivated plants without, for example, withering.

If a nonwoven fabric made of a natural biodegradable fiber such as coconut shell is laid on the bottom surface of the cultivation container 11 (not shown), drainage and the like can be held well and bed rot can be prevented. In addition, sufficient ventilation can be ensured for the lower end of the soil.

[0034] The plant cultivation container 10 of the present invention may have some kind of support member (not shown). For example, a support member, which is a frame made of synthetic resin or metal, can be provided on the outer wall surface of the plant cultivation container. The support member may have a configuration in which the plant cultivation container is housed inside and the plant cultivation container is supported from the outer wall surface, or may be mounted inside the plant cultivation container to support the plant cultivation container from the inside. May be provided. Further, the support member may be provided detachably on the plant cultivation container, or may be permanently attached to the plant cultivation container.

Next, a method for cultivating a plant using the plant cultivation container 10 according to the present invention will be described.

First, on the bottom of the bottomed cultivation container 11,
The sheet 12 is wound in a roll shape so as to have substantially the same diameter as the bottom surface of the cultivation container 11, and a cylindrical body 13 fixed with a wire is mounted thereon, and is placed on the ground or on a support base.
In addition, if the top of the cylindrical body 13 is formed to have the same height as the opening of the cultivation container 11, various operations such as watering can be easily and efficiently performed. Therefore, the height dimension of the cylindrical body 13 is not particularly limited, and can be implemented by appropriately changing the design.

Next, a desired amount of soil for plant cultivation is filled in the cylindrical body 13 and fertilizer is applied if necessary. After that, seeds of the plant are seeded or seedlings of the plant grown in advance are prepared. After planting, the plants are grown to a desired size while repeatedly watering or the like.

When the plant is cultivated in this way, the lower end of the cylindrical body 13 is only placed on the bottom surface of the bottomed cultivation container 11, and the cultivation container 11 and the cylindrical body 13 Since a gap 16 that can guide the outside air to the lower end of the cylindrical body 13 is formed in the cultivation container 11 and the cylindrical body 13, the following operation occurs.

At the lower end of the cylindrical body 13, when the root of the plant extending in the cultivation soil reaches the bottom surface of the cultivation container 11, the root of the plant is formed between the bottom surface and the lower end of the cylindrical body 13. While trying to poke outward through the gap, the root tips of the plant are pruned (also called air prunes) by external air.

Furthermore, the root of the plant that has reached the inner surface of the cylindrical body 13 tries to turn around the inner periphery of the cylindrical body 13, but a plurality of convex portions and concave portions are alternately formed on the side wall of the cylindrical body 13. Since it is formed, sufficient air permeability can be secured outside the soil. That is, the root of the plant that has reached this wall surface is suppressed from growing by contact with air. In addition, since the root is subjected to air pruning in this way, root branching is induced from a portion other than the tip of the root that has been pruned, and even if the growing and growing root reaches the wall surface, the root remains inside the container body. The plant does not go around and the growth of the plant is good.

Further, the cylindrical body 13 is placed in the cultivation container 11.
Is loaded, heat rays and the like represented by direct sunlight can be reflected by the cultivation container 11, and the cylindrical body 1
3, both light-shielding and heat-shielding effects are obtained. That is, particularly in the summer, it is possible to prevent the soil from drying abnormally due to a rise in the temperature of the soil in the cylinder and the like, thereby preventing the cultivated plant from withering. That is, the cultivated plant can be stably and satisfactorily grown.

Further, the cylindrical body 1 is placed on the bottom of the cultivation container 11.
Since the lower end of 3 is not integrally formed, a slight gap is formed between the lower end of the cylindrical body 13 and the bottom surface of the cultivation container 11, and has a suitable air permeability and drainage (water retention). Both can be secured. Also in this case, the growth of the plant is promoted.

Next, when the plant cultivated in the cylindrical body 13 reaches a desired size, it can be easily removed by opening the cylindrical body 13 and forming the original sheet 12. That is, since the root mass 17 exists in a bare state on the bottom surface of the cultivation container 11, it can be easily taken out without damaging the root, and can be easily transplanted to an open field for planting or another cultivation or display container. Or it can be planted. In other words, complicated work such as rooting to facilitate the roots of the plants cultivated in the cylindrical body 13 to take root in the transplanted soil is not required at all, and such transplanting workability can be improved, and rooting after fixation can be achieved. Excellent rate.

In the gap 16 'between the outer surface of the root mass 17 and the inner wall surface of the bottomed cultivation container 11, a cultivation soil R, a permeable soil (or a material for promoting ventilation) S, or a water-absorbing polymer is provided. When the water-retaining material T typified by a water-containing substance or a water-containing natural body is refilled and filled, the plant cultivation structure 20 according to the present invention can be constructed (FIG. 6).

The cultivation soil to be supplemented and filled is a permeable soil (or a ventilation promoting material) S in which the proportion of the resin foam is larger than that of the artificial soil filled in the cylindrical body 13.
The use of is preferred because it is extremely lightweight, is excellent in drainage and can secure air permeability, is easy to handle, can prevent root rot and the like, and has good plant growth. The gap 16 'may contain a water-retaining material T represented by a water-absorbent polymer, a water-containing nonwoven fabric, or a water-containing natural body such as agar or gelatin. In this case, there is an operational effect that it is not necessary to irrigate every day, for example, even during transportation or during a short absence.

However, the plant cultivation structure according to the present invention is a plant cultivation structure 20 using the cylindrical body 13.
Instead, for example, a plant cultivated in another known cultivation container, the plant taken out from the cultivation container is stored in the cultivation container 11, and then the cultivation soil R is wrapped around the root nodule of the plant. , Breathable soil or ventilation promoting material S, or
It is assumed that the term is used to include all the refills of any of the water retention materials T.

When a plant is cultivated in such a structure for plant cultivation, if, for example, a dressing pot for display and sale is used as a bottomed cultivation container, the cultivated plant can be conventionally used. The operation of planting in another cultivation or display container is not required, and an operational effect is obtained that a series of processes from plant cultivation to in-store display can be performed in the same cultivation container.

Next, the plant cultivation container of the second embodiment according to the present invention comprises a sheet 12 having a plurality of through holes as described above.
Is wound into a roll to form a cylindrical body 13.
Is substantially the same as that of the plant cultivation container 10 of the above-described first embodiment, except that is loaded into the bottomed cultivation container 11.

According to the container for plant cultivation of the second embodiment adopting such a configuration, in addition to the above-described respective effects produced by the container for plant cultivation of the first embodiment, a plurality of through holes are formed in the wall surface of the cylindrical body 13. Is present, the root extending to the outside of the cylindrical body 13 through the through hole causes enlargement on the inside and / or outside of the wall of the cylindrical body 13. When the cylindrical body 13 is taken out, the root is easily cut off at the wall surface of the cylindrical body 13.

When, for example, the cultivation soil R is replenished between the root mass 17 and the bottomed cultivation container 11 and the cultivation is continued as it is, a large number of roots having enlarged ends are formed. Plants having roots with enlarged ends will exhibit extremely good viability when transplanted to other soils.

The plant having such an enlarged part with fine roots, cultivated in this way, exhibits extremely good viability when transplanted to another soil. The reason for this is that a large number of roots are generated from the enlarged ends, and the roots rapidly absorb water and nutrients in the transplanted soil.

Further, since there are a plurality of through holes in the wall surface of the cylindrical body, roots extending toward the cylindrical body are subjected to air pruning. Branching is induced, and it is possible to prevent root winding along the inner wall of the cylindrical body, and the growth of the plant is improved.

The container for cultivating plants according to the second embodiment is, in particular, an embodiment of the invention described in claim 2.

According to the plant cultivation method using the plant cultivation container of the first embodiment or the plant cultivation container of the second embodiment described above, the plant is cultivated while ensuring sufficient air permeability to the soil. The root branching is induced from a part other than the tip of the pruned root, and even when the growing and extending root reaches the wall surface, the root does not go around the inner peripheral surface of the container body, and the plant grows well.

After cultivating the plant to a desired size, the cylinder can be easily opened and removed, and the root extended in the cylinder and the soil used for plant cultivation can be removed. Can be stored in a bottomed cultivation container as it is, and the space between the outer surface of the root mass and the inner wall surface of the bottomed cultivation container can preferably be filled with breathable soil. In other words, there is no need to plant in another cultivation or display container. For example, when a decorative pot for display and sale is used, a series of processes from plant cultivation to store display are performed in the same cultivation container. it can.

When transplanting the cultivated plant to another place, the root of the plant cultivated in the cylinder can be taken out in the state of the root mass, so that it is easy to take root in the transplanted soil. This eliminates the necessity of any complicated work such as the necessity of laying, thereby improving the transplanting workability and improving the survival rate after fixing.

[0057]

As described above, according to the container for cultivating plants according to the first and second aspects, it is possible to reduce the length of the roots along the inner peripheral surface of the container for cultivating plants with a simple structure. It can prevent the growth of roots, and in particular, can carry out a series of processes from tree seedling cultivation, transportation, and display at stores in the same cultivation container, and plant it in another container for plant cultivation. According to the plant cultivation method according to the third aspect or the structure for plant cultivation according to the fourth or fifth aspect, it is easy to manage the plant cultivation, and the plant is planted in another container for plant cultivation. There is no need to do so, and when planting plants in other places, no complicated work such as rooting to make it easy to take root in the soil of the planting destination is unnecessary, and exceptionally excellent effect in terms of excellent survival rate after fixing It is extremely effective It is excellent.
