Description

[Technical Field]

[0001] The present invention relates to a stackable cultivation container that allows plants to be easily cultivated vertically. [Background technology]

[0002] With the global population increasing and the number of people working in agriculture decreasing, the issue of securing food through agriculture is becoming a serious problem, and an effective solution would be to cultivate large quantities of plants on a small amount of land with a small number of people. Vertical cultivation is the way to achieve this, and to make this possible, cultivation equipment has been developed that allows plants to be grown by stacking them vertically.

[0003] One example of a vertical cultivation device is one that has a planter on each shelf, but these shelves are large-scale equipment and the hurdles to introducing them are high. Therefore, cultivation containers that allow plants to be planted vertically in the form of seedlings or plants have been developed. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6249153 Summary of the Invention [Problem to be solved by the invention]

[0005] The cultivation container described in Patent Document 1 is configured so that plants can be cultivated by inserting them into diagonal pipes that branch off from a vertically connected series of pipes and running water through the pipes. However, with this configuration, the spaces in which all the plants are planted are interconnected, which requires a constant flow of water, and is not fully capable of dealing with the situation when the plants grow, their stems extend, or their roots become overgrown.

[0006] In view of the above problems, the present invention aims to provide a cultivation container that can be stacked vertically and that allows environmental adjustment for each plant. [Means for solving the problem]

[0007] The present invention, which solves the above problem, is a cultivation container comprising a main body portion and a holding portion capable of holding an insert, wherein the main body portion has side walls surrounding a central axis, a bottom surface portion intersecting the central axis, and a connecting portion that can be connected in the direction of the central axis, and the holding portion is arranged on the side walls so as to bulge in a direction away from the central axis and is connected to the main body portion. With this configuration, it is possible to create a cultivation container that can be stacked vertically and that allows environmental adjustment for each plant stock.

[0008] In a preferred embodiment of the present invention, the main body has a discharge portion that protrudes from the bottom surface in the direction of the central axis, and the discharge portion has a discharge port spaced a predetermined height from the bottom surface. This configuration allows the water in the main body to be kept at an appropriate level.

[0009] In a preferred embodiment of the present invention, the edge of the opening of the holding portion is higher than the discharge port in the direction of the central axis. This configuration prevents water from leaking out of the holder.

[0010] In a preferred embodiment of the present invention, the device further comprises an extension portion connectable to the main body portion in the direction of the central axis. With this configuration, the height and spacing of the main body can be adjusted to suit the length of the plant stem.

[0011] In a preferred embodiment of the present invention, the device further comprises a lid portion that can be attached to the holding portion. This configuration holds the plants more securely and reduces exposure of water in the cultivation container.

[0012] In a preferred embodiment of the invention, the lid has an insert into which the insert can be inserted. This configuration makes it easier to plant and harvest the plants being cultivated.

[0013] In a preferred embodiment of the present invention, the shape of the outer edge portion when viewed from the direction of the central axis has rotational symmetry. With this configuration, when stacking the cultivation containers, the direction of the holding parts can be changed by a predetermined angle. [Effects of the Invention]

[0014] The present invention, which solves the above-mentioned problems, provides a cultivation container that can be stacked vertically and allows environmental adjustment for each plant stock. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, a cultivation container X according to an embodiment of the present invention will be described with reference to the drawings. The description will be made in detail in the order of the configuration of the embodiment, the method of implementation, and other examples. The following embodiments are merely examples of the present invention, and the present invention is not limited to the following embodiments.

[0017] <Embodiment> As shown in Figures 1(a) and 1(b), the cultivation container X according to this embodiment includes a main body 1 and a holder 2 capable of holding an insert, and is stackable vertically. Furthermore, as shown in Figure 5, the cultivation container X includes an extension portion 3 and a lid portion 4, enabling efficient vertical cultivation of a variety of plants. In the following description, the direction of the central axis A in each drawing is referred to as the height direction (vertical direction).

[0018] As shown in Figures 1(a), 1(b), and 2(a), the main body 1 is a box-shaped or cylindrical container having a bottom surface 11 that intersects with the central axis A and a side wall 12 that surrounds the central axis A, and further has a connecting portion 13 that can connect the cultivation containers X to each other in the direction of the central axis, and a discharge portion 14 that can discharge liquids and the like stored inside.

[0019] The bottom surface portion 11 is a flat plate-like member having a surface direction on a plane centered on the central axis A and intersecting the central axis A approximately perpendicularly, and forms the bottom portion of the cultivation container X. In the drawings, the bottom surface portion 11 is square (or a square with rounded corners) when viewed in the height direction (direction of the central axis A), but other shapes may be used as long as they have rotational symmetry about the central axis A. Examples include a regular polygon, circle, ellipse, and star-shaped shape. From a mathematical perspective, shapes with evenly rounded corners are also accepted for shapes with corners. With this configuration, when the main body portions 1 are stacked vertically, their orientation can be changed by a predetermined angle around the central axis A, thereby changing the direction in which the holding portion 2 (described later) bulges out.

[0020] The side walls 12 are one or more plate-like members that are erected along the outer edge of the bottom surface 11 in the planar direction and surround the central axis A, providing the main body 1 with a vertical height. The height of the side walls 12 is preferably 8 cm to 30 cm, more preferably 10 cm to 25 cm, and even more preferably 12 cm to 20 cm. With this configuration, the height of the main body 1 becomes equivalent to the size of seedlings of many plants (crops, flowers, etc.), allowing the inserted object (plant) to be cultivated at a size appropriate for the plant and making it easy for the user to handle.

[0021] In addition to the plate-like configuration, the side wall 12 is preferably configured to have reinforcing members in both the height direction and the direction intersecting the height direction (which may be perpendicular or oblique). These reinforcing members are beam-like members that protrude from the surface of the side wall 12, particularly from the outer surface (the surface facing away from the central axis A), and suppress flexural deformation of the side wall 12. This configuration can improve the strength of the main body 1 and also enhance the design. Furthermore, the side wall 12 is preferably configured to have a lid locking hole S that can lock and connect the lid 4. With this configuration, the lid 4 can be attached stably.

[0022] 1(a) and 1(b), the connecting portion 13 is provided further below the bottom surface portion 11 in the height direction and near the upper edge of the side wall 12, and a penetration portion 131 and a locking body 132 are provided below the bottom surface portion 11, and a locking hole 133 is provided near the upper edge of the side wall 12. This allows the main body portions 1 to be stacked vertically and connected to each other for use.

[0023] The penetration portion 131 is a frame-shaped member that extends below the bottom portion 11 in the height direction (opposite the side wall 12) and is a combination of flat and curved plates, and the shape of the outer edge portion as viewed in the height direction is substantially the same as the shape formed by the inner peripheral surface of the side wall 12 around the central axis A. As a result, when multiple cultivation containers X are stacked vertically, the penetration portion 131 of the upper cultivation container X penetrates into the inside of the side wall 12 of the lower cultivation container X to connect them. The length of the penetration portion 131 in the height direction is shorter than the length from the upper edge of the side wall 12 to the holding portion 2. As a result, when multiple cultivation containers X are stacked and connected vertically, the holding portion 2 and the penetration portion 131 do not interfere with each other, and the same cultivation conditions can be ensured for all cultivation containers X.

[0024] As shown in Figures 1(a) and 1(b), the locking body 132 is a member provided to protrude from a surface of the penetration portion 131 that can come into contact with the side wall 12, and can be fitted into the locking hole 133. As shown in Figures 1(a) and 1(b), the locking hole 133 is a recess or through-hole provided near the upper edge of the side wall 12, particularly in the area where the penetration portion 131 penetrates, and can be fitted into the locking body 132. With this configuration, the connection of multiple growing containers X by the penetration portion 131 can be made more stable.

[0025] As shown in FIGS. 2(a) and 2(b), the main body 1 has a discharge section 14 capable of discharging fluids (water, aqueous solution containing fertilizer, etc., mixed liquid, etc.) stored therein. The discharge section 14 is a cylindrical member that protrudes axially in the height direction (direction of the central axis) from the bottom surface 11, and has a discharge outlet D provided at a predetermined distance in the height direction from the bottom surface 11. The discharge section 14 is preferably provided in a plurality of configurations with different shapes. In this embodiment, a first discharge section 141, a second discharge section 142, and a third discharge section 143 are provided, and the configuration of the discharge outlet D is different for each. This configuration allows the cultivation container X to be easily adapted to a variety of cultivation methods.

[0026] The first discharge portion 141 protrudes upward in the height direction from the bottom surface portion 11 (to the same side as the side wall 12), has a closed upper end surface, and has a discharge outlet D provided in the cylindrical side surface portion. Here, it is preferable that the discharge outlets D are provided in multiple locations at the same position in the height direction. This configuration increases the amount of fluid that can be discharged simultaneously, and more reliably keeps the amount of fluid inside the cultivation container X constant. In addition, the height of the discharge outlets D from the bottom surface portion 11 is preferably 3 cm or more and 6 cm or less, more preferably 4 cm or more and 5.5 cm or less. This configuration can also be used to cultivate aquatic plants whose roots or stems need to be partially submerged in water.

[0027] The second discharge portion 142 protrudes upward in the height direction from the bottom surface portion 11 (to the same side as the side wall 12), and its upper end is open to form a discharge outlet D. It is preferable that the height of the discharge outlet D of the second discharge portion 142 from the bottom surface portion 11 is higher than the discharge outlet D of the first discharge portion 141. With this configuration, even if the flow rate of the fluid flowing into the growing container X exceeds the amount that can be discharged by the first discharge portion 141, the second discharge portion 142 can handle it. Moreover, in order to increase the amount of fluid discharged, a plurality of second discharge portions 142 may be provided.

[0028] The third discharge portion 143 protrudes downward in the height direction from the bottom surface portion 11 (to the same side as the penetration portion 131), and has an open lower end surface to provide a discharge outlet D. This allows water to flow downward when soil is placed in the cultivation container X to cultivate a plant, using the same principle as a hole in the bottom of a well-known flowerpot. Furthermore, the length of the third discharge portion 143 in the height direction is shorter than that of the penetration portion 131. This configuration allows the cultivation container X to be stably installed on a flat installation location.

[0029] In the configuration of the main body 1 shown in Figures 2(a) and 2(b), the first discharge portion 141, the second discharge portion 142, and the third discharge portion 143 are arranged at positions off the central axis A, so that a total of four discharge portions 14 surround the central axis A. This arrangement is merely one example, but with this configuration, when multiple main body portions 1 are stacked, regardless of the orientation of the main body portions 1, the fluid discharged from the discharge portion 14 of the upper main body portion 1 flows down near the discharge portion 14 of the lower main body portion 1, so that the fluid is efficiently discharged and the amount of fluid inside the main body portion 1 can be easily kept stable.

[0030] In arranging the discharge sections 14, it is preferable that the third discharge section 143 is positioned closest to the holding section 2. With such a configuration, when the roots of the plants held in the holding section 2 grow, they are less likely to be hindered, and a better cultivation environment can be created.

[0031] As shown in FIGS. 1(a) and 1(b), the holder 2 is a box-shaped member that bulges away from the central axis A on the side wall 12 of the main body 1 and can hold an inserted object (such as a plant seedling), and has a bulging wall 21 and an opening 22. The interior of the holder 2 is connected to the main body 1, and part or all of the connection with the side wall 12 is open. With this configuration, the holder 2 can hold a plant while supplying the plant with fluids (water, fertilizer, etc.) that have flowed into or are stored inside the main body 1. Furthermore, the roots of the plant held by the holder 2 can penetrate into the interior of the main body 1 and grow thrivingly, making it easier for the plant to grow.

[0032] The main body 1 and the holding part 2 are configured in the same way even if they do not have the shapes shown in the drawings. The main body 1 is a member that can be stacked and connected in the direction of the central axis A with the side walls 12 and connecting parts 13, and forms an integrated cylindrical assembly in the direction of the central axis A. The part that bulges outward from the central axis A is the holding part 2, and above the holding part 2 there is a space that allows the head of the inserted object (the part located at the top of the plant, such as a stem, leaf, or flower) to escape to the outside of the main body 1. As long as the above conditions are met, the main body 1 and the holding part 2 of this embodiment may have any shape, including the shape shown in the drawings.

[0033] The bulging wall 21 is a thin wall surface that determines the shape of the holding portion 2 and, together with the main body 1, allows fluids, soil, etc. to be stored inside. The bulging wall 21 has a bulging angle H, which indicates the maximum inclination angle from the side wall 12, as shown in FIG. 1(b). In this embodiment, the bulging angle H is preferably 30 degrees or more and 60 degrees or less, more preferably 35 degrees or more and 55 degrees or less, and even more preferably 40 degrees or more and 50 degrees or less. This configuration allows the inserted object to be appropriately released from the main body 1 while being held at an appropriate angle that is not too horizontal. Furthermore, the bulging wall 21 is preferably configured with a lid locking hole S that can be used to lock and connect the lid 4. This configuration allows the lid 4 to be stably attached.

[0034] The opening 22 allows an insert to be inserted into an area at the top of the holding part 2 where there is no bulging wall 21. As shown in Fig. 1(a), the opening 22 is preferably configured to be open over substantially the entire top of the holding part 2. With such a configuration, when caring for the cultivation containers X, for example, when disassembling multiple stacked cultivation containers X or cleaning the insides of the cultivation containers X, the user's hands can easily reach the inside of the holding part 2, and the cultivation containers X can be easily handled.

[0035] In the direction of the central axis A, the height of the lowest part of the edge of the opening 22 is higher than all of the outlets D of the outlet portion 14. With this configuration, the fluid stored inside the main body 1 and the holding portion 2 is discharged from the outlets D, and the fluid does not leak from the edge of the holding portion 2. Furthermore, the height of the lowest part of the edge of the opening 22 is preferably 5 mm or more higher than the outlet D located at the highest position, and more preferably 1 cm or more higher. With this configuration, the surface tension of the fluid can be accommodated and the fluid can be more reliably drained from the outlets D.

[0036] As shown in Figures 3(a), 3(b), and 5, the expansion part 3 is a tubular member that can expand the cultivation container X, particularly the main body part 1, in the vertical direction, and has an expansion side wall 31 and an expansion connecting part 32. This allows the upper or lower side of the main body part 1 to be raised, and the height of the cultivation container X can be adjusted to match the length of the insert inserted into the holding part 2 (the height of the plant stem).

[0037] Like the side walls 12 of the main body 1, the extension side walls 31 are one or more plate-like members that surround the central axis A and provide vertical height to the extension section 3. Furthermore, it is preferable that the shape of the extension side walls 31 as viewed from the direction of the central axis A is substantially the same as that of the side walls 12 of the main body 1 (or the outer shape of the bottom section 11), and that the shape has rotational symmetry around the central axis A. With this configuration, the shape of the main body 1 can be maintained and the extension sections 3 can be stacked vertically.

[0038] The extension side wall 31 is preferably configured so that its height is shorter than that of the side wall 12 of the main body 1. This configuration allows for more precise adjustment of the height of the cultivation container X, particularly the space above the holding portion 2. Similarly to the side wall 12 of the main body 1, the extension side wall 31 is preferably configured so that reinforcing members are provided on the surface of the plate-like member, particularly on the outer surface (the surface facing away from the central axis A), in both the height direction and the direction intersecting the height direction (which may be perpendicular or oblique). This configuration not only improves the strength of the extension portion 3, but also unifies the appearance with the main body 1, improving the design.

[0039] The expansion connecting part 32, like the connecting part 13 of the main body part 1, is provided further below the expansion side wall 31 in the height direction and near the upper edge of the expansion side wall 31, with an expansion penetration part 321 and an expansion locking body 322 provided on the lower side and an expansion locking hole 323 provided near the upper edge of the expansion side wall 31. This allows the expansion parts 3 and the main body part 1 to be stacked vertically and connected to each other for use.

[0040] The expansion penetration portion 321 is a frame-shaped member that extends below the expansion side wall 31 in the height direction and is a combination of flat and curved plates, and the shape of its outer edge as viewed in the height direction is substantially the same as the shape formed by the inner peripheral surface of the expansion side wall 31 around the central axis A. As a result, when multiple cultivation containers X are stacked vertically, the expansion penetration portion 321 of the upper cultivation container X penetrates into the interior of the expansion side wall 31 of the lower cultivation container X to connect them. The length of the expansion penetration portion 321 in the height direction is shorter than the length from the upper edge of the side wall 12 of the main body portion 1 to the holding portion 2. As a result, when multiple expansion portions 3 are stacked and connected above the main body portions 1, the holding portion 2 and the expansion penetration portion 321 do not interfere with each other, ensuring the same cultivation conditions for all cultivation containers X.

[0041] As shown in Figures 3(a) and 3(b), the expansion locking body 322 is a member provided to protrude from a surface of the expansion penetration portion 321 that can come into contact with the expansion side wall 31, and can be fitted into the expansion locking hole 323. As shown in Figures 3(a) and 3(b), the expansion locking hole 323 is a recess or through-hole provided near the upper edge of the expansion side wall 31, particularly in the area where the expansion penetration portion 321 penetrates, and can be fitted into the expansion locking body 322. With this configuration, the connection of multiple growing containers X by the expansion penetration portion 321 can be made more stable.

[0042] As shown in Figures 4(a), 4(b), and 5, the lid 4 is a member that closes the upper opening 22 of the holder 2, and has a lid main body 41 and an insertion part 42 that can be inserted into the internal space of the holder 2. This not only allows the inserted object (plant) to be supported in a stable position, but also prevents the fluid (especially water) stored inside the main body 1 and the holder 2 from being exposed to the air, and prevents the intrusion of dust and dirt, as well as evaporation.

[0043] Lid main body 41 is a plate-like member that corresponds to the shape around the outer edge of opening 22, and closes the inside of opening 22 so that it does not expose the inside. Lid main body 41 also has a hole near the center in the planar direction of the plate, allowing an insert (plant) to be inserted, and has a locking portion 411 along the outer edge.

[0044] The locking portion 411 is a columnar or claw-shaped member that protrudes from the outer edge of the lid main body 41, and can be locked with a lid locking hole S provided in the side wall 12 or the bulging wall 21. With this configuration, the lid 4 can be stably attached to the main body 1 and the holding portion 2.

[0045] The insertion portion 42 is a tubular member that communicates with the hole in the lid main body 41 and extends toward the inside of the holder 2, and supports the inserted object (plant) within the range of its length and cross-sectional area. Furthermore, as shown in FIG. 5, when the lid 4 is attached to the main body 1 and the holder 2, the length of the insertion portion 42 is short enough so that it does not abut against the bottom surface 11 of the main body 1, and it is preferable that the insertion portion 42 is configured to be approximately parallel to the bulging angle H of the bulging wall 21, or that the tip of the insertion portion 42 can be positioned near the third discharge portion 143. This configuration creates ample space around the tip of the insertion portion 42, preventing the roots of the cultivated plant from being forcibly bent.

[0046] The insertion portion 42 has a plurality of side holes 421 formed in the wall surface forming the tubular member. The side holes 421 are small holes arranged in an array on the insertion portion 42, particularly on the side opposite the lid main body portion 41. This configuration allows the roots of plants inserted into the insertion portion 42 to easily escape. As shown in Figures 4(a) and 4(b), the side holes 421 are preferably arranged in a rectangular cross section with the longitudinal direction being the length of the insertion portion 42. This configuration allows many side holes 421 to be formed without compromising the strength of the entire insertion portion 42.

[0047] The insertion portion 42 is preferably configured to have a fastening hole 422 in addition to the side hole 421. The fastening hole 422 is a small hole that penetrates the wall surface in the radial direction of the tubular member of the insertion portion 42, and the hole diameter is preferably such that a thin stick (such as a well-known toothpick or bamboo stick) can be inserted therethrough, for example, approximately 1 mm to 3 mm, and more preferably 1.2 mm to 2.5 mm. With this configuration, a plant seedling inserted into the insertion portion 42 can be supported by a thin stick, allowing smaller seedlings to be cultivated in the cultivation container X.

[0048] The present invention may have the following configurations. However, the following configurations are merely examples, and the presence or absence of the configurations can be determined arbitrarily unless otherwise specified.

[0049] <Example of change> In the embodiment shown in the drawings, the locking bodies 132, the extending locking bodies 322, the locking holes 133, and the extending locking holes 323 are provided in two locations per surface of the side wall 12 or the extending side wall 31, but they may be provided in one location or in three or more locations per side as long as they have rotational symmetry about the central axis A. With this configuration, the user does not need to consider the orientation of anything other than the holding part 2 when connecting the main body part 1 and the extending part 3, making it easier to handle the cultivation container X.

[0050] The holding portion 2 may bulge in multiple directions in one main body 1. While the embodiment shown in the drawings has one holding portion 2, two or more holding portions 2 may be provided. For example, two holding portions 2 may be provided on both sides of a pair of opposing side walls 12. With this configuration, plants can be planted and cultivated from both sides of the cultivation container X without having to alternately flip the orientation of the main body 1 180 degrees and stack them as shown in FIG. 6. However, this configuration is preferably applied to plants whose stems and roots are relatively short even after growth, so as not to inhibit plant growth. With this configuration, as shown in FIGS. 5 and 6, more plants can be cultivated even if the assembled cultivation container X is installed in a single location.

[0051] In each embodiment shown in the drawings, the holding portion 2 bulges out from a portion of the side wall 12, but it may also be configured to bulge out using the entire horizontal area of ​​the side wall 12. In particular, as long as the side wall 12 having the holding portion 2 has a locking hole 133 along the upper edge, the range over which the holding portion 2 bulges out can be determined arbitrarily.

[0052] Hereinafter, a method for carrying out the present invention will be described in detail with reference to the drawings. The ...

[0053] <<Implementation Method>> The method for carrying out the present invention varies depending on the plant cultivation method. Below, the method for carrying out the present invention in soil cultivation and the method for carrying out the present invention in hydroponic cultivation will be described in detail as examples.

[0054] <Soil cultivation> In the case of soil cultivation, the user first puts soil inside the main body 1. In the case of plants that can be grown on a porous base (such as a sponge) instead of soil, the user spreads the porous base over the bottom surface 11. At this time, it is preferable to place a net or the like on the third discharge section 143 in advance to prevent soil particles from falling. The user can also put soil inside the holder 2 as needed to ensure the necessary soil height for the plants.

[0055] Next, the user stacks the main body 1 filled with soil and the extension portion 3 vertically as needed, and connects them together. At this time, the penetration portion 131 or the extended penetration portion 321 penetrates into the lower side wall 12 or the extended side wall 31, and the locking body 132 or the extended locking body 322 engages with the lower locking hole 133 or the extended locking hole 323 to connect them. The order in which the main body 1 and the extension portion 3 are stacked is arbitrary (FIG. 6 shows an example in which the main body 1 and the extension portion 3 are alternately stacked), and the orientation of the holding portion 2 around the central axis A may be changed to match the rotational symmetry of the main body 1 and the extension portion 3.

[0056] Next, the user inserts a plant seedling or the like into the insertion portion 42, inserts the insertion portion 42 into the inside of the holding portion 2, and attaches the lid main body portion 41 to the side wall 12 and the bulging wall 21. This allows the plant to be planted in the cultivation container X. The user then repeats the same operation to plant plants in all of the holding portions 2.

[0057] After plants have been planted in the cultivation container X using the above procedure, the user pours fluid (water, fertilizer, etc.) into the top of the cultivation container X, spreading the fluid all the way down to the bottom of the main body 1. At this time, the fluid flows down successively from the outlet D into the main body 1 below, so it is sufficient to pour the fluid into one place at the top.

[0058] When disassembling the cultivation container X, the user disassembles each component in the reverse order of the above. When changing the stacking order of the main body 1 and the extension part 3, the same procedure as above is followed.

[0059] <Hydroponic cultivation> In the case of hydroponic cultivation, the user first closes the outlet D of the third outlet part 143. This allows the fluid (water) to be stored inside the main body part 1. At this time, the liquid level inside the main body part 1 is set to the height of the outlet D of the first outlet part 141, but if a lower liquid level is desired, the tube of the second outlet part 142 is cut so that the outlet D is at the desired height.

[0060] Next, the user stacks the main body portion 1 and the extension portion 3 vertically as needed and connects them to each other. At this time, the penetration portion 131 or the extended penetration portion 321 penetrates into the lower side wall 12 or the extended side wall 31, and the locking body 132 or the extended locking body 322 engages with the lower locking hole 133 or the extended locking hole 323 to connect them. The order in which the main body portion 1 and the extension portion 3 are stacked is arbitrary (FIG. 6 shows an example in which the main body portion 1 and the extension portion 3 are alternated), and the orientation of the holding portion 2 around the central axis A may be changed to match the rotational symmetry of the main body portion 1 and the extension portion 3.

[0061] Next, the user inserts a plant seedling or the like into the insertion portion 42. At this time, if the aquatic plant seedling to be inserted is grown on a base such as a porous material (sponge, etc.) or cotton and is inserted into the insertion portion 42 together with the base, it is preferable to insert a thin stick (toothpick, bamboo stick, etc.) into the fastening hole 422 to fix the base and prevent the plant from falling off.

[0062] The user then inserts the insertion part 42 with the plant inserted into the holder 2 and attaches the lid main body 41 to the side wall 12 and the bulging wall 21. This plants the plants in the cultivation container X. The user then repeats the same operation to plant plants in all of the holders 2.

[0063] After plants have been planted in the cultivation container X using the above procedure, the user pours fluid (water, fertilizer, etc.) into the top of the cultivation container X, spreading the fluid all the way down to the bottom of the main body 1. At this time, the fluid flows down successively from the outlet D into the main body 1 below, so it is sufficient to pour the fluid into one place at the top.

[0064] When disassembling the cultivation container X, the user disassembles each component in the reverse order of the above. When changing the stacking order of the main body 1 and the extension part 3, the same procedure as above is followed. [Explanation of symbols]
