Description

The present invention relates to a root clogging improvement support pot that can easily improve clogging of perennial plants, perennial plants and the like cultivated under root area restrictions such as ornamental plants and bonsai. In particular, the present invention relates to a root clogging improvement support pot that assists in removing an appropriate amount of fine roots that are likely to cause deterioration of the soil environment in plants and the like that are cultivated under root area restrictions.

Conventionally, in artificial planting of flowers and small trees, a container cultivation method for cultivating using a cultivation container such as a pot has been widely performed.
Here, there are two main purposes for planting.
The first purpose is to grow the plant greatly, and there are things that gradually increase the volume by selecting cultivation containers such as pots according to the plant growth stage, such as budding, raising seedlings, and fixed planting. .
The second purpose is found in the case of bonsai and ornamental plants, and does not grow large plants, but keeps a fixed size under the restriction of the root zone and improves the appearance. The size of the container may vary depending on the state of the plant, but it does not actively repot large pots.

In the prior art, many cultivation containers have been invented and disclosed for various purposes.
Many of them are in accordance with the first purpose described above and are called so-called seedling pots. Many of the materials are made of synthetic resin sheets such as polyolefin and polyester, and synthetic fiber nonwoven fabrics. The seedling pot is intended to solve the problem that moisture and nutrients important for promoting the development of fine roots do not sufficiently permeate into the container and the amount of fine roots in the container is suppressed, and grows the root as large as possible. The purpose is to plant the plant without damaging it.

  For example, the container disclosed in Japanese Patent Laid-Open No. 2000-50741 actively promotes the generation of fine roots in the container, and improves the survival rate by removing the container with almost no damage to the tips of the fine roots when planting. In order to actively promote the generation of fine roots in the container, a fine hole processing of about 10 to 100 microns is performed while making the roots and the root-insulating container impervious to fine roots. The water, fertilizer, oxygen, etc. necessary for the growth of the tree from the fine holes of about 100 microns are replenished to promote the growth of the tree and the generation of fine roots in the container.

  On the other hand, the situation differs between ornamental plants and bonsai. Ornamental plants and bonsai do not actively promote plant growth, but rather moderately control growth. As materials, pottery, unglazed bricks, plastics, synthetic resins, wood, etc. are used to limit the root area. In this way, the plant under the restriction of the root region extends in a vertical and horizontal direction from the thick root to the small and medium roots in the container. However, after 1 to 2 years, it becomes a so-called root pot and root clogging occurs. As a result, the activity of the root is weakened, and the plant may be damaged due to growth failure.

  In addition, for example, the container disclosed in Japanese Patent Application Laid-Open No. 2001-136848 also actively promotes the generation of fine roots in the container, and when planting, the container is removed with almost no damage to the tips of the fine roots, and the survival rate The main objective is to improve When a root-shielding container such as the container disclosed in Japanese Patent Application Laid-Open No. 2000-50741 is used, all the roots, medium and small roots and fine roots are entangled and become small and the growth of fine roots is not promoted. Since there is a problem, in the container disclosed in Japanese Patent Laid-Open No. 2001-136848, the fine roots are extended outward by providing pores, the fine roots are grown, and moisture and nutrients are passed through the outwardly extended fine roots. It is intended to promote plant absorption and grow plants.

JP 2000-50741 A JP 2001-136848 A

However, the conventional container has the following problems.
Containers intended for large growth of plants aim to increase the absorption efficiency of moisture and nutrients by extending fine roots and hair roots in the space inside the container. Roots intertwined with each other are likely to be formed. When such a root pot is formed, the activity of the root is weakened due to a decrease in the oxygen concentration in the soil or the like, and the above-ground plant body is weakened. In order to improve the activity of roots, it is necessary to improve such root clogging. In order to improve root clogging, it is necessary to either transplant to a container with a larger volume or remove excess small and medium roots from the root pot. When cultivating under the restriction of root area such as ornamental plants and bonsai, the volume of the container cannot be increased, and therefore, it is necessary to take measures to remove excess small and medium roots. However, removing extra fine roots and hair roots from root pots in which fine roots and hair roots are intertwined vertically and horizontally requires great effort and skill.

  In addition, traditional ornamental plants and bonsai pots are often chosen to have small capacities, so that the roots and hair roots do not grow excessively. The point that it is formed is the same.

The present invention provides a root clogging improvement support pot that can easily remove excess small and medium roots from a root pot in order to maintain the activity of the root in the cultivation of plants under root area restriction in order to solve the above problems. The purpose is to provide.

In order to solve the above problems, roots clogging improvement supporting bowls of the present invention, under the root zone limit, a root clogging improvement support pots to assist in the removal of unwanted fine roots in the root ball, pots for root zone limit A main body, a container selected to fit within the bowl main body , and a number of fine root through holes provided on the wall surface of the container, and the diameter of the fine root through hole allows only unnecessary fine roots to pass therethrough. It is characterized by having a root clogging improvement supporting container that has a diameter and that facilitates cutting off the fine roots coming out from the fine root through-holes in a state of being taken out from the bowl body during cleaning.

With the above configuration, the growth of fine roots and hair roots from the thick roots and small roots of the plant itself cannot be suppressed on the growth of the plant, but when a root pot that is intertwined vertically and horizontally is formed, it extends outward from the fine root through hole. By cutting off the fine roots and hair roots, unnecessary fine roots and hair roots can be easily removed, and the soil in the root clogging improvement support pot can be replaced with new soil at the time of care.

As a configuration example of the root clogging improvement support bowl of the present invention, a container includes a side wall part and a bottom dish part, and the bottom dish part is fitted and locked on the inner peripheral wall of the side wall part, and both are combined.
For example, the side wall part forms an inverted frustoconical side surface whose diameter decreases as it goes from the upper surface side to the bottom surface side, and the side wall part fits on the inner wall surface of the side wall part. It is preferable to include a bottom plate height adjusting mechanism that adjusts the position to be engaged and locked so that the volume of the container can be adjusted.

As a specific structural example, the side wall portion forms an inverted truncated cone side surface whose inner diameter decreases as it goes from the upper surface side to the bottom surface side, and the bottom plate portion is fitted at a position where the inner wall surface of the side wall portion has substantially the same diameter. It is combined by locking, and the diameter of the side wall is adjusted by the diameter adjusting mechanism, and the position where the bottom pan is fitted and locked on the inner wall surface of the side wall is adjusted.
According to the above configuration, the root clogging improvement support bowl of the present invention can appropriately change the size of the root clogging improvement support container that fits in the bowl body, and can increase the inner diameter of the root clogging improvement support container. The height of the bottom plate can also be adjusted.

In the root clogging improvement support container to be housed in the pot body of the root clogging improvement support bowl of the present invention having the above-described configuration, the following device can be applied.
A first device is to change the diameter of the fine root through-hole according to the position of the side wall. For example, among the inner wall surfaces of the side wall portion, the one provided on the side wall near the upper surface is large, and the hole diameter of the fine root through hole is changed so as to become smaller toward the bottom surface side.
By changing the hole diameter of the fine root through hole in this way, it is considered that roots that extend near the top of the root clogging improvement support container, that is, in the lateral direction, are considered to be less important for planting. It can be taken out as unnecessary roots. On the contrary, since the importance as a root becomes higher as it goes to the lower surface direction, the hole can be made smaller and fine fine roots and hair roots protruding outward from the fine root through hole can be cut out as unnecessary roots.
Moreover, for example, a large diameter and a small diameter can be mixed as the hole diameter of the fine root through hole. By mixing the large fine root through hole and the small fine root through hole, the ratio of the relatively thick fine root and the relatively thin fine root can be appropriately equalized.

  The second device is a device in the form of the edge of the fine root through hole. The edge of the fine root through hole is devised so as to be convex toward the outer side of the container. For example, it is assumed that the bulge protrudes outward. In this way, by projecting the edge of the fine root through-hole outward in a three-dimensional convex shape, it becomes easier to take out the root clogging improvement support container from the pot soil, and the edge of the fine root through-hole projects outward. Therefore, it becomes easy to apply a pruning shear etc. to the edge of the fine root through hole, and it becomes easy to cut out the fine root and the hair root.

  The third device is a device that provides a taper that decreases in diameter toward the inner wall surface of the fine root through hole. By providing a taper that reduces the diameter of the inner wall of the fine root through-hole in this way, it is easy to pass through the fine root through-hole from the inside to the outside of the root clogging improvement support container, but the root clogging is improved. It becomes difficult to pass through the fine root through hole from the outside to the inside of the support container. In other words, fine roots and hair roots that extend outward from the roots and small roots of plants pass easily through the fine root through-holes, but fine roots and hair roots that have once gone outward from the fine root through-holes are pots. Even if the direction is changed due to obstruction, etc., it is possible to prevent the root clogging improvement support container from entering back into the interior from the outside.

By using the root clogging improvement support bowl of the present invention, it is possible to guide the roots and hair roots to extend outward so that root pots that are intertwined vertically and horizontally are not formed. By cutting the hair root, unnecessary fine roots and hair roots can be easily removed.
In addition, since the radish is in the root clogging improvement support container, anyone can easily remove only the unnecessary fine roots without being accidentally removed or damaged, and the above-ground plant body is weakened. Is not invited.
Moreover, there is also an advantage that the soil can be easily replaced when the root clogging improvement supporting container stored in the pot body is taken out and returned to the pot body again.
Further, the size of the root clogging improvement support container can be changed as appropriate, the inner diameter of the root clogging improvement support container can be expanded, and the height of the bottom plate portion can also be adjusted.
In addition, by changing the hole diameter of the fine root through hole, the root extending near the upper surface of the root clogging improvement support container, that is, the root extending in the lateral direction, is cut by guiding a relatively thick fine root outward and cutting downward. Can also be devised that only relatively thin fine roots are guided outward and cut off.
If the edge of the fine root through hole is convex toward the outer side of the container, the edge of the fine root through hole protrudes outward, so that a pruning shear or the like is applied to the edge of the fine root through hole. It becomes easy and excision of fine roots and hair roots becomes easy.

Hereinafter, embodiments of the root clogging improvement support bowl of the present invention will be described with reference to the drawings. However, it goes without saying that the scope of the present invention is not limited to those shown in the following examples.

A configuration example of the root clogging improvement support bowl 300 according to the first embodiment of the present invention will be described .
FIG. 1 is a diagram simply illustrating a configuration example of a root clogging improvement support bowl 300 according to the first embodiment of the present invention. 1A is a diagram simply showing the relationship between the pot body 200 and the root clogging improvement support container 100, FIG. 1B is a front view, FIG. 1C is a plan view, and FIG. 1D is a perspective view. Is shown.

The root clogging improvement support bowl 300 according to the first embodiment of the present invention includes a pot body 200 and a root clogging improvement support container 100 that fits into the pot body 200.
As shown in FIG. 1, the root clogging improvement support container 100 according to the first embodiment of the present invention has a size that fits inside a pot body 200 such as ceramic. That is, the root clogging improvement support container 100 is used by being put into the bowl body 200. For example, the volume ratio occupied by the root clogging improvement support container 100 with respect to the bowl body 200 can be selected, for example, from about 40 to 80%.

The outer shape of the entire root clogging improvement support container 100 is not particularly limited, and may be any shape that substantially conforms to the shape of the inner surface of the applied bowl main body 200. The root clogging improvement support container 100 has a side wall surface 110 and a bottom plate surface 120. That is, the side wall surface 110 and the bottom plate surface 120 may have various shapes such as a cylindrical shape, a rectangular tube shape, and a mortar shape. Here, a substantially inverted frustoconical shape (conical shape) that is often found in bowls and the like is taken as an example.

  The material of the root clogging improvement support container 100 is not limited, and plastic, metal, synthetic resin, chemical fiber, nonwoven fabric, and the like can be widely applied.

  The side wall surface 110 and the bottom plate surface 120 of the root clogging improvement support container 100 may be a separate type or an integral type. The type in which the side wall surface 110 and the bottom plate surface 120 are separated will be described in another example, and the root clogging improvement support container 100 according to the first embodiment will be described as an integral type.

As shown in FIG. 1, the side wall surface 110 and Sokosaramen 120 of the container that will fit in the pot body 200, it has become a large number of fine roots through holes 130 provided on the wall surface is provided. The diameter of the fine root through hole 130 is a diameter through which only the fine root can penetrate. The diameter of the fine root through-hole 130 is selected according to the size of the bowl body 200 to be applied. For example, as the diameter of the fine root through-hole 130 of the root clogging improvement supporting container 100 applied to the No. 5 bowl, The diameter can be about 2 to 3 mm. Further, for example, the diameter of the fine root through hole 130 of the root clogging improvement support container 100 applied to the No. 10 bowl can be set to about 3 to 4 mm in diameter, for example.

The number of fine root through-holes 130 is not particularly limited, but the number of fine root through-holes 130 is large in order to cope with many fine roots generated from many directions and to improve drainage in the root clogging improvement support container. It is preferable to provide it. For example, in this configuration example, the area ratio of the holes occupying the wall surface is about 70 to 90%.
In the configuration example shown in FIG. 1, the diameter and number of the fine root through-holes 130 are the same for both the side wall surface 110 and the bottom plate surface 120, but the size and number of the diameters are high in the clogging improvement support container 100. An example of changing according to this will be described later.

A method of using the root clogging improvement support bowl 300 according to the first embodiment will be described.
FIG. 2 is a diagram for explaining a procedure for using the root clogging improvement support bowl 300 according to the first embodiment of the present invention. The left figure compares the case of root clogging improvement support pot 300 according to Example 1 of the present invention, and the right figure shows a case of planting only a conventional pot.

As shown in the left figure of FIG. 2 (a) , the root clogging improvement support container 100 is put into the pot body 200 according to the state of the plant, and the plant to be planted is put into the root clogging improvement support container 100 together with the soil. Then, the soil is also introduced between the pot body 200 and the root clogging improvement support container 100. In addition, the state of the root is simply shown so that the state in the root clogging improvement support container 100 at the time of planting can be easily understood.

On the other hand, as shown in the right figure of Fig.2 (a), the plant planted with respect to the pot main body 200 is thrown in with soil. Similarly, the state of the root is simply shown so that the state in the root clogging improvement support container 100 at the time of planting can be easily understood.

When the period elapses (for example, one year), the roots grow and a large number of fine roots and hair roots grow in addition to the thick roots and medium / small roots.
Here, as shown in FIG.2 (b), in order to perform the process which cuts off an unnecessary fine root and a hair root, a plant is taken out from the pot main body 200. FIG.
As shown in the left diagram of FIG. 2B, when the root clogging improvement support container 100 is inserted, a large number of fine roots and hair roots extending outward pass through the fine root through holes 130 of the root clogging improvement support container 100 as they are. And spread to the surroundings. In addition, after exiting the fine root through-hole 130 of the root clogging improvement support container 100, since there is a wall surface of the bowl main body 200, the extending direction is changed, and generally extends along the wall surface of the bowl main body 200. Therefore, there is mainly no root or medium root between the outer periphery of the root clogging improvement support container 100 and the inner periphery of the pot body 200, and a root pot in which a large number of fine roots and hair roots are intertwined is formed.

On the other hand, as shown in FIG. 2 (b) right figure, when planted directly plants against conventional pot, in the entire inner space of the conventional pot, most comprehensive Futoshine, in addition to small roots, A root pot in which many fine roots and hair roots are intertwined is formed.

Next, as shown in FIG. 3 (a), the fine roots and hair roots are loosened moderately in order to perform treatment for cutting off unnecessary fine roots and hair roots.
In the case of the root clogging improvement support bowl 300 according to the first embodiment of the present invention, as shown in the left diagram in FIG. Since it does not come out, the fine roots and hair roots are not intertwined with the thick roots and the small and medium roots, and are mainly root roots with only fine roots and hair roots intertwined.

On the other hand, as shown in the right figure of FIG. 3 (a), when a plant is planted directly in a conventional pot , a root in which numerous fine roots and hair roots are intertwined in length and breadth in addition to a thick root and a medium root. A pot is formed, the root pot cannot be easily loosened, and it may be cut to a thick root or a middle root, which has a great adverse effect on plants.

Next, as shown in FIG.3 (b), the treatment which cuts out an unnecessary fine root and a hair root is performed.
3B, in the case of the root clogging improvement support bowl 300 according to Example 1 of the present invention, the root pot has been loosened to some extent mainly on the outer periphery of the root clogging improvement support container 100. Since the fine roots and hair roots are protruding from the fine root through hole 130 in the form, the fine roots and hair roots protruding from the fine root through hole 130 may be cut along the outer periphery of the root clogging improvement support container 100.

3B, in the case of the root clogging improvement support bowl 300 according to the first embodiment of the present invention, the root clogging improvement support vessel 100 exits from the fine root through hole 130 along the outer periphery thereof. Since it is only necessary to cut off the fine roots and hair roots, anyone can easily carry out and the influence on the plant can be minimized.
Further, since the soil inside the root clogging improvement support container 100 is kept clean, the soil outside the root clogging improvement support container 100 can be easily replaced with new soil.

On the other hand, as shown in the right figure of FIG. 3 (b), when a plant is planted directly in a conventional pot , a root in which numerous fine roots and hair roots are intertwined in length and breadth in addition to a thick root and a medium root. Since a pot is formed, it is not easy to cut only fine roots and hair roots from the root pot. There is a strong risk of cutting radishes and small and medium roots together.
Therefore, as shown in the right figure of FIG. 3 (b), when a plant is planted directly in a conventional pot, from root pots in which fine roots and hair roots are intertwined with the roots, medium roots and roots indefinitely. To cut directly the fine roots and hair roots, the roots and small and medium roots are also cut off, and the plant body is often weakened, and in severe cases, it will die.

Inventor Satoshi Araki conducted a simple experiment to confirm the effect of the root clogging improvement support bowl 300 of the present invention.
FIG. 4A shows a state in which one year has passed after planting an ornamental plant to which the prototype root clogging improvement support pot 300 was applied in a rectangular pot. In addition, the root clogging improvement support container 100 made as a prototype is easily made into a rectangle using a wire mesh material.
FIG. 4B is a photograph showing a state in which an ornamental plant is taken out from the pot main body 200 together with the root clogging improvement support container 100. It can be seen that the root pots are formed by covering the outer peripheral surface with fine roots and hair roots.
FIG. 4C is a photograph showing a state in which fine roots and hair roots that are in a root pot state covering the outer peripheral surface of the root clogging improvement support container 100 are loosened. It was very easy to loosen the fine roots and hair roots.
FIG.4 (d) is a photograph which shows a mode that the fine root and hair root which covered the side wall surface among outer peripheral surfaces were cut off. Since the fine roots and hair roots were loosened, it was relatively easy to cut the fine roots and hair roots with the pruning shears.
FIG.4 (e) is a photograph which shows a mode that the fine root and hair root which covered the bottom face among the outer peripheral surfaces were cut off. Since the fine roots and hair roots were loosened, the fine roots and hair roots could be easily cut with a pruning shears.
FIG. 4 (f) shows a state where the fine roots and hair roots that have covered the outer peripheral surface of the root clogging improvement support container 100 are cut out and then returned to the pot body 200 again. The new soil is replaced with the bottom and side surfaces of the root clogging improvement support container 100, and the maintenance work is completed.

As described above, if cultivation is performed using only ordinary pots, root pots in which fine roots and hair roots are intertwined vertically and horizontally with respect to thick roots and medium roots are formed. On the other hand, by using the root clogging improvement support bowl 300 of the present invention, only the extra fine roots and hair roots are extended outward from the fine root through hole 130, and the outer periphery of the root clogging improvement support container 100 and the inner periphery of the pot main body 200 are extended. A root pot can be formed with only fine roots and hair roots in between. Thereby, it is possible to easily cut out the fine roots and hair roots coming out from the fine root through holes 130 along the outer periphery of the root clogging improvement support container 100.

A root clogging improvement support bowl 300a of the present invention according to Example 2 will be described.
The root clogging improvement support bowl 300a according to the second embodiment of the present invention incorporates various ideas with respect to the basic form of root clogging improvement support bowl 300 shown in the first embodiment.

The first device is a device in which the hole diameter of the fine root through hole 130 is changed according to the position of the side wall portion 110. FIG. 5A is a diagram illustrating a state in which the hole diameter of the fine root through hole 130 is changed according to the position of the side wall portion 110.
In this configuration example, as shown in FIG. 5A, the hole diameter of the fine root through hole 130 provided on the side wall near the top surface of the inner wall surface of the side wall portion 110 is large, and is provided on the side wall as it goes to the bottom surface side. The diameter of the fine root through hole 130 is small. As described above, the diameter of the fine root through-hole 130 is increased in accordance with the position (height) of the side wall portion 110 and the vicinity of the bottom surface is decreased, whereby the thickness of the fine roots and hair roots that can be passed can be controlled. . That is, for fine roots and hair roots that extend laterally from the plant and reach the side wall surface near the upper portion of the root clogging improvement support container 100, since there is a fine root through hole 130 having a relatively large diameter, a comparison corresponding to the pore diameter is made. It can pass through the fine roots of the target level.

On the other hand, for fine roots and hair roots that extend downward from the plant and reach the side wall surface near the bottom surface of the root clogging improvement support container 100, since there is a fine root through hole 130 having a relatively small diameter, a comparison corresponding to the pore diameter is made. Can pass only fine thin roots.
For roots extending near the upper surface of the root clogging improvement supporting container 100 , that is, in the lateral direction, relatively thick fine roots can be taken out of the root clogging improvement supporting container and cut out as unnecessary roots by the procedure according to the first embodiment. it can. On the other hand, the roots extending downward can cut out only fine fine roots and hair roots protruding outward from the fine root through-holes 130 having a small hole diameter as unnecessary roots.

In this way, by changing the diameter of the fine root through hole, it is possible to adjust the thickness of unnecessary fine roots and hair roots according to the height in the root clogging improvement support container 100 .
Moreover, for example, a large diameter and a small diameter can be mixed as the hole diameter of the fine root through hole. By mixing the large fine root through hole and the small fine root through hole, the ratio of the relatively thick fine root and the relatively thin fine root can be appropriately equalized.

Next, the second device is a device for the shape of the edge of the fine root through hole 130. FIG. 5 is a diagram showing a device in which the shape of the edge of the fine root through hole 130 is convex toward the outside.
As shown in FIG.5 (b), the edge of the fine root through-hole 130 is made to protrude outward three-dimensionally in a convex shape. A large number of protrusions having a hole in the center are provided.

As shown in FIG. 5 (b), if the protruding member rootlets through hole 130 is the hole in the center is opened, as shown in FIG. 2 (b), the root clogging improvement support vessel 100a of pot body 200 It is easy to remove from the soil, and since the edge of the fine root through-hole 130 protrudes outward, it becomes easy to apply a pruning shear etc. to the edge of the fine root through-hole 130, and the effect of facilitating excision of the fine root and hair root Is obtained. If the edge of the fine root through hole 130 is not convex outward and is flat, the fine root or hair root is cut by applying a pruning shear along the cylindrical outer surface. If the edge of the fine root through-hole 130 is convex outward as shown in (b), the part to which the pruning shears are applied protrudes outward, so further cut the fine roots and hair roots by applying the pruning shears. It becomes easy.

  Next, the third device is a device for the shape of the inner wall surface of the fine root through-hole 130, and is a device for providing a taper that decreases in diameter toward the outside on the inner wall surface. FIG. 6 is a view showing an example in which a taper that decreases in diameter toward the outside is provided as the shape of the inner wall surface of the fine root through-hole 130. It is simply shown enlarged in cross-sectional area.

  As shown in FIG. 6 (a), by providing a taper that decreases in diameter on the inner wall surface of the fine root through-hole 130, the direction in which the fine roots and hair roots pass can be controlled. Although it is easy to pass through the fine root through-hole 130 from the inside to the outside of the clogging improvement support container 100, an effect is obtained that it is difficult to pass through the fine root through-hole 130 from the outside to the inside of the clogging improvement support container 100.

This device is effective for preventing the reversal of fine roots and hair roots. That is, as shown in FIG. 6B, fine roots and hair roots extending outward from the plant roots and small roots of the plant pass through the fine root through holes 130 and exit outward. When fine roots and hair roots that have gone out from 130 are blocked by the pot body 200 or the like and change their direction, they may lose their place and extend back in the root clogging improvement support container 100, When a taper is provided on the inner wall surface of the fine root through-hole 130, as shown in FIG. 6C, the inside of the root clogging improvement supporting container 100 is easily passed through the fine root through-hole 130 and goes outward. However, it is difficult for the root clogging improvement support container 100 to pass from the inside to the inside of the fine root through hole 130, and the fine roots and hair roots are prevented from returning to the inside of the root clogging improvement support container 100 and entering the inside. Can do.

The root clogging improvement support bowl 300b according to the first embodiment of the present invention has a structure in which the side wall part 110 and the bottom dish part 120 are separable.
FIG. 7 is a diagram simply illustrating the structure of the root clogging improvement support container 100b of the root clogging improvement support bowl 300b according to the third embodiment of the present invention. As shown in FIG. 7, the root clogging improvement support container 100b includes a side wall portion 110b and a bottom plate portion 120b. The bottom plate portion 120b is fitted into the inner peripheral wall surface of the side wall portion 110b, is fitted and locked, and both are combined.

  In the configuration example shown in FIG. 7, the side wall portion 110 b has an inverted truncated cone shape whose diameter decreases from the top surface side toward the bottom surface side. In this configuration example, the side wall portion 110 b includes a diameter adjustment mechanism that adjusts the diameter. is there. As shown in FIG. 7B, hook-shaped fasteners 140 are intermittently provided around the side wall portion 110b, and the position of the side wall portion 110b is adjusted by adjusting the position of the hook-shaped fastener 140. It is a diameter adjustment mechanism that adjusts the diameter.

Although the pot body 200 is selected according to the size of the plant to be planted and the growth state, it is necessary to select the root clogging improvement support container 100 according to the size of the selected pot body 200. In the root clogging improvement support container 100b according to Example 3, since the side wall part 110b includes a diameter adjusting mechanism that adjusts the diameter, the diameter appropriately matches the size of the selected pot body 200. The diameter of the side wall part 110b of the root clogging improvement support container 100b is adjusted.

  The bottom plate portion 120b is provided with a bottom plate portion height adjusting mechanism that adjusts the position of fitting and locking on the inner wall surface of the side wall portion 110b. The outer peripheral wall surface of the bottom plate portion 120 is provided with a taper that matches the taper of the inner peripheral wall surface of the side wall portion 110b, and has an inverted frustoconical shape. The shape is easy to be done.
