  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a cross-sectional view of a flower pot 10 showing an embodiment of the present invention. As shown in FIG. 1, the flower pot 10 includes a bottom wall portion 16 that forms a bottom wall portion, a thick portion from the bottom wall portion 16 to a predetermined height, and a thin portion from the predetermined height to the upper end. And a side wall 12 which is a structure. The bottom wall portion 16 is provided with a plurality of holes 11 penetrating in the vertical direction (vertical direction), and a root cutting hole 15 that intersects the plurality of holes 11 substantially vertically and is formed in a slit shape in the horizontal direction. ing.

  The hole 11 is formed so that the root of the plant can extend from the inside of the flower pot 10 to the outside when the flower pot 10 is used for plant cultivation. The root cutting hole 15 is formed so that a root passing through the hole 11 can be cut from the outside of the flower pot 10 using, for example, a commercially available cocoon.

  The side wall part 12 has the shelf part 13 formed by the thickness difference of the said thick part and the said thin part. Here, when the side wall part 12 supports the other flower pot 10 with which the shelf part 13 was piled up from the upper side, it is formed so that the root cutting hole 15 of the other flower pot 10 piled up may not be hidden. To do.

  Next, the cultivation method performed using the flower pot 10 is demonstrated. In the present embodiment, the case where three flower pots 10 (flower pot 10A, flower pot 10B, flower pot 10C) are used will be described as an example. The size of the container to be used is selected on the condition that other containers can be supported by the shelf 13.

  Next, the cultivation method performed using the flower pot 10 is demonstrated. In the present embodiment, the case where three flower pots 10 (flower pot 10A, flower pot 10B, flower pot 10C) are used will be described as an example. The size of the container to be used is selected on the condition that other containers can be supported by the shelf 13. In this example, three flower pots 10 were selected so that the side wall portion 12 gradually increased in thickness (see FIG. 3).

  First, the growth stage of the plant to be cultivated is divided into a plurality of stages. In this example, using commercially available eggplant seedlings as cultivation targets, the eggplant growth stages from this state were classified into first to third growth stages. Note that the first growth stage is the time until eggplant roots are sufficiently rooted in the soil in the flower pot 10A, and the second growth stage is the time until the eggplant roots extend into the flower pot 10B. The following was designated as “third growth stage”. Eggplant is a kind of vegetable that has deep roots.

  Next, as shown in FIG. 2, a plant pot 10A is filled with a soil 14a suitable for the first growth stage, and eggplant seedlings are planted. In this example, the soil 14a used was a mixture of red soil, compost, lime superphosphate, chemical fertilizer, and others. The soil 14a may be filled up to a position higher than the position of the shelf portion 13a. The container for planting eggplant seedlings first may not have the shelf 13.

  When the roots of eggplant are sufficiently rooted in the soil 14a, the soil 14b suitable for the second growth stage is filled to a position slightly higher than the shelf 13b of the flower pot 10B, and the flower pot 10A is overlaid on the upper side of the flower pot 10B ( (See FIG. 3). At this time, the flower pot 10A is supported by the shelf 13b by aligning the bottom surface of the flower pot 10A with the shelf 13b. By supporting the flower pot 10A by the shelf 13b, it is possible to prevent excessive pressure from being applied to the soil 14b. In this example, the soil 14b used was a mixture of red soil, compost, lime superphosphate, chemical fertilizer, and others.

  Further, when the eggplant root reaches the soil 14b, the soil 14c suitable for the third growth stage is filled to a position slightly higher than the shelf 13c of the flowerpot 10C, and the flowerpot 10B is overlaid on the upper side of the flowerpot 10C (FIG. 3). reference). At this time, the flower pot 10B (also the flower pot 10A superimposed on the flower pot 10B) is supported by the shelf 13c by aligning the bottom surface of the flower pot 10B with the shelf 13c. In this example, the soil 14c used was a mixture of red soil, compost, superphosphate lime, chemical fertilizer, and the like at a different ratio from the soil 14b. FIG. 3 is a cross-sectional view showing an example of a cross section of the flower pots 10A, 10B, 10C in a state of being stacked as described above. As shown in FIG. 3, since the shelf 13c of the flowerpot 10C located at the bottom supports the other flowerpots (10A, 10B) that are overlaid, a large pressure is not applied to the soil 14c. ing. In addition, it is good also as a structure which provides a space between the upper surface of the soil with which each flower pot is filled, and the bottom face of a flower pot.

  Furthermore, as shown in FIG. 4 (A), when the roots of eggplant reach the soil 14c and the eggplant is in a state sufficiently grown for harvesting, root cutting is performed using the root cutting holes 15a, As shown in FIG. 4B, the flower pot 10A is removed from the flower pot 10B. At this time, as described above, the root cutting hole 15a is formed so as to be able to cut the root passing through the hole 11a from the outside of the flower pot 10A using, for example, a commercially available cocoon. There is no need to lift.

  Using the working time (seconds) when carrying out the present invention to carry out the root cutting work (separation work between the flower pot 10A and the soil 14b before the end of cultivation in fruit vegetables such as eggplant and tomato), the root cutting hole Table 1 shows the working time (seconds) when the root cutting work is performed in each of the flower pots having a conventional structure that does not have 15a as the target section. As shown in Table 1, it becomes possible to shorten the work time of the root cutting work, and the labor of the root cutting work can be greatly reduced.

  In addition, root removal is carried out using the chemical component (nitrate ion) content (mg / kg vegetable weight) when one week has passed since the root cutting operation was performed on the sunny lettuce grown according to the present invention. The chemical component (nitrate ion) content (mg / kg vegetable weight) of the previous sunny lettuce is shown in Table 2 as the target section. As shown in Table 2, a chemical component such as nitrate ion absorbed by the sunny lettuce from the soil is digested, and a highly safe sunny lettuce with a low content of the chemical component is obtained. That is, by performing root cutting work, it is possible to cultivate low nitrate vegetables (not only sunny lettuce but also other leaf vegetables (leaf vegetables) or fruit vegetables).

  As described above, in the above-described embodiment, the plant cultivation container (for example, the flower pot 10) used for plant cultivation has an upper surface opened, and the bottom wall (for example, the bottom wall 16) has upper and lower portions. A plurality of holes (for example, the hole 11) are formed in the direction, and a root cutting hole (for example, the root cutting hole 15) that intersects all the plurality of holes substantially perpendicularly is formed. Since the structure is characterized in that a support portion (for example, a shelf portion 13) for supporting other containers stacked from above is formed, even if a plurality of containers are stacked, the container located on the upper side and the inside thereof The pressure applied to the soil inside the container (for example, soil 14b, soil 14c) located on the lower side due to the weight can be reduced, and in the cultivation method in which a plurality of containers are stacked, the labor required for root cutting work is reduced. Can be So as to.

  That is, since the root cutting of the plant can be performed using the root cutting hole, it is possible to perform the root cutting operation of the plant to be cultivated without lifting the container located in the upper stage and remove it from the container located in the lower stage. become able to.

  Further, in the above-described embodiment, the side wall portion has a two-stage structure having a thick portion from the bottom wall portion to a predetermined height and a thin portion from the predetermined height to the upper end, and the thick portion and the thin portion. Since the other container is supported by the shelf formed by the shelf (for example, the shelf 13), the pressure applied to the soil inside the container located on the lower side is excessive when the containers are stacked with a simple structure. Can be prevented.

  Moreover, in embodiment mentioned above, it is a cultivation method of a plant, Comprising: The growth stage of the plant (for example, eggplant) to be cultivated is classified into two or more stages, the upper surface is opened, and the bottom wall portion is A plurality of holes (for example, holes 11) are formed in the direction, and a root-cutting hole (for example, a root-cutting hole 15) that intersects the plurality of holes (for example, all of the holes) substantially perpendicularly is formed. A plurality of root-cutting holes that intersect each other, and a plurality of root-cutting holes may cover all of the plurality of holes), and another container that is stacked on the side wall (for example, the side wall 12) from above. A plurality of containers for plant cultivation (for example, flowerpots 10A) having a support portion (for example, shelf 13) for supporting the above are prepared (for example, flowerpots 10A to 10C), and one of the containers (for example, flowerpot 10A) is prepared. And soil mixed with fertilizer according to the first growth stage (example: The plant seeds or seedlings are planted using a container filled with soil 14a) and filled with soil mixed with fertilizer according to the first growth stage as a first growth stage container. When reaching the second growth stage, one of the containers (for example, the flower pot 10B) supports the soil corresponding to the second growth stage (for example, the soil 14b), and the support section (for example, the shelf section 13b) supports the other containers. A support portion that is filled up to a height (for example, a position slightly higher than the shelf 13b), and the first growth stage container is formed into a second growth stage container filled with soil for the second growth stage. Is supported on the upper side of the container for the second growth stage, and then the bottom container (for example, the container 10B) is used for the next growth stage according to the growth of the plant to be cultivated. (For example, the soil 14c) is a support portion (for example, The shelf portion 13c) is supported by a support portion (for example, the shelf portion 13c) formed in a container (for example, the container 10C) filled to a height near the height at which the other container is supported (for example, a position slightly higher than the shelf portion 13c). When a plant to be cultivated satisfies a specific condition (for example, when it has grown sufficiently to be harvested), a root cut hole is placed on the upper side of the container (for example, container 10C). Since the root of the plant to be cultivated is cut, the container positioned at the upper stage including at least the first growing stage container is removed from the container positioned at the lower stage, and the growth is advanced. You can use as much soil as necessary for the growth stage of the cultivation target, and even if multiple containers are stacked, the soil filled in the bottom container is over-pressed and inhibits the growth of the cultivation target Can Absent. Furthermore, even if such a cultivation method is used, the labor required for root cutting work can be reduced.

  In the above-described embodiment, the container other than the first growth stage container is filled with the soil up to a height slightly higher than the height at which the support portion supports the other containers, so that the container positioned on the lower side. The container located on the upper side is supported by the support part formed on the container located on the lower side in a state where the upper surface of the soil filled in and the bottom surface of the container located on the upper side are in close contact with each other.

  Depending on the nature of the plant to be cultivated, the supporting portion is filled with soil to a height lower than the height supporting other containers, and the upper surface of the soil filled in the lower container is positioned on the upper side. The container positioned on the upper side may be supported by the support portion formed on the container positioned on the lower side in a state where a gap is formed between the bottom surface of the container.

  Although not particularly mentioned in the above-described embodiment, as shown in FIGS. 5A and 5B, the thickness of the side wall 12b extends from the upper surface of the side wall 12b to the inside of the side wall 12b. A groove (side wall groove 17b) that reaches the inner wall of the meat part is formed. For example, when the container 10A is supported by the shelf part 13b, the structure may be a space that leads from the outside to the inside of the container 10B, that is, the soil 14b. good. By adopting the above structure, it is possible to secure a method for supplying oxygen to the roots to prevent rooting in anaerobic conditions, and to directly fertilize and water the soil filled in a container on which other containers are stacked. It becomes possible.

  Although not specifically mentioned in the above-described embodiment, the bottom wall portion 16 may have a structure in which at least one groove (bottom wall groove) is formed. By adopting such a structure, it is possible to secure a method for supplying oxygen to the roots to prevent rooting in anaerobic conditions, and to directly fertilize and water the soil filled in the container on which other containers are stacked. Is possible.

  Further, the flower pot 10 may be configured such that the bottom wall portion 16 includes a cutting unit that cuts a root (for example, eggplant root) passing through the plurality of holes 11 in the vertical direction. In this case, for example, the bottom wall portion 16 may be provided with the root cutting blade 18. By adopting such a structure, options of methods that can be used when root cutting is increased, and the efficiency of root cutting can be improved.

  Hereinafter, the plant root cutting means using the root cutting blade 18 will be described with reference to the drawings.

  FIG. 6 is a cross-sectional view showing an example of a flower pot 10 in which a root cutting part 19 having a root cutting blade 18 is provided in the root cutting hole 15. As shown in FIG. 6, it is assumed that a root cutting blade 18 is formed in the root cutting portion 19 in accordance with the location of the hole 11 in the bottom wall portion 16. Furthermore, the root cutting part 19 shall be formed so that it can be moved or rotated in the horizontal direction from the outside of the flower pot 10. By setting it as such a structure, it becomes possible to cut | disconnect the root of the plant which passes the hole 11 by moving the root cutting part 19. FIG.

  As shown in FIG. 7, the root cutting part 19 may have a structure provided at a position that does not overlap with the position of the root cutting hole 15, and further, by providing a fastener 20, contrary to the intention of the user. It is good also as a structure which can prevent that root cutting is performed.

  Further, as shown in FIG. 8, the root cutting blade 18 may be provided on the outer edge of the hole 11. With this structure, root cutting can be performed by rotating the flower pot 10. In this case, in order to reduce labor required for root cutting, a structure may be adopted in which one of the side wall portion 12 and the bottom wall portion 16 is fixed and one of the side wall portion 12 and the bottom wall portion 16 is rotatable.

  In addition, in order to reduce the force required for root cutting by the root cutting blade 18, the hole 11 may be arranged so as to be biased toward the outer edge of the bottom wall portion 16. That is, when the flower pot 10 is rotated, the root cutting blade 18 positioned on the outer edge side of the bottom wall portion 16 is larger than the root cutting blade 18 positioned on the center side of the bottom wall portion 16 due to the lever principle. It can be used that force acts.

  In the above-described embodiment, the three flower pots 10 are selected so that the thickness of the side wall portion 12 increases stepwise. However, the present invention may be implemented using three flower pots 10 of exactly the same size. it can. FIG. 9 is a cross-sectional view showing an example of a cross section in a state where the flower pots 10 of the same size are stacked. In this case, when preparing a plurality of plant cultivation containers (for example, the flower pot 10), it is not necessary to prepare a plurality of flower pots, which is useful.

  However, when a large number of containers for plant cultivation are stacked, considering the balance of the whole container and the load applied to the container located in the lower stage, for example, the support part (for example, the shelf part 13) is gradually increased in thickness. A container for plant cultivation may be selected.

  According to the present invention, in the cultivation method in which the growth proceeds while sequentially stacking the containers, when a plurality of containers are stacked, the container positioned on the upper side and the soil inside the container positioned on the lower side due to the weight inside the container. It is useful for reducing the applied pressure and reducing the labor required for the root cutting work.
