  The plant cultivation sheet of the present invention (Claim 6) is used by placing the entire sheet in a cultivation container such as a flower pot or a planter and putting in a soil. In this case, a planter having a large number of holes at the bottom or a box having no liquid-tightness at the bottom can be easily made into a cultivation container having a water holding portion of a desired water level. Since the sheet is flexible, the water level can be adjusted while maintaining high liquid-tightness by simply interposing a plate material between the base and the bottom of the planter.

  Next, embodiments of the water level regulating drainage and the plant cultivation sheet of the present invention will be described with reference to the drawings. FIG. 1 is a partially cutaway plan view showing an embodiment of the water level adjusting drainage device of the present invention, FIGS. 2 and 3 are longitudinal sectional views showing the use state of the water level adjusting drainage device of FIG. 5 is a partially cut-out plan view and longitudinal sectional view showing another embodiment of the water level regulating drainage of the present invention, respectively, and FIG. 6 is a longitudinal sectional view before assembly showing an embodiment of the plant cultivation sheet of the present invention. 7 is a sectional view taken along line VII-VII of the cap in FIG. 6, and FIG. 8 is a sectional view showing a use state of the plant cultivation sheet in FIG.

  1 and 2 includes a main body 11 and a cover or cap 12 screwed into the main body. As shown in FIG. 2, the main body 11 includes a disk-shaped base 14 having an opening 13 formed in the center, and a cylindrical protrusion 15 rising from the periphery of the opening 13 of the base. A circular shallow concave portion 16 is formed on the lower surface of the base 14, and a disk-shaped sealing material (gasket) 17 is accommodated in the concave portion and joined with an adhesive or the like. The thickness of the sealing material 17 is somewhat thicker than the depth of the recess 16. An opening having the same diameter as the base opening 13 is also formed in the center of the sealing material 17. A male screw 18 is formed on the outer periphery of the protruding portion 15.

  The cap 12 includes a cylindrical outer peripheral wall 21, a top surface 22 that closes the upper end of the outer peripheral wall, an inner cylinder 23 concentric with the outer peripheral wall 21, and a plurality of sheets that connect the outer peripheral wall 21 and the inner cylinder 23. It consists of ribs 24. The ribs 24 are, for example, about 4-8 and are arranged radially. In this embodiment, the inner cylinder 23 does not reach the top surface 22, and the inner cylinder 23 is supported by the ribs 24. Therefore, a gap is provided between the top surface 22 and the upper end of the inner cylinder 23, and the rib 24 is also omitted in the gap portion. On the inner surface of the inner cylinder 23, a female screw that is screwed with the male screw 18 of the protruding portion 15 of the main body is formed. A notch 25 for guiding water is formed at the lower end of the outer peripheral wall 21. The cutout portion 25 is preferably a small opening in order to reduce entry of the soil. As the main body 11 and the cap 12, an injection molded product of a synthetic resin such as vinyl chloride or polyethylene can be used. However, it may be made of metal.

  The water level adjusting drain device 10 configured as described above is installed, for example, on the bottom portion 27 of the flower pot 26 shown in FIG. 2 so as to surround the drain port 28 formed at the bottom portion. The flower pot 26 is further filled with a soil 29, and a plant is planted in the soil for cultivation. When water is applied to the soil 29 from above, if there is no water level control drainage device 10, most of the water flows out from the drain outlet 28 except for the amount contained in the soil 29. When the water level adjusting drainage 10 is installed, the drainage port 28 is blocked by the base 14 and the sealing material 17, and therefore does not flow out of the drainage port 28 and accumulates in the flower pot 26. When the water level H reaches the upper end of the protrusion 15, the water flows into the protrusion 15 and flows out from the opening 13 at the lower end. Therefore, an appropriate water level H is maintained.

  In addition, what is necessary is just to interpose inclusions, such as a board | plate material or a block, between the base 14 and the bottom part 27 of the flower pot 26 when a higher water level is required. In that case, the inclusions are provided with upper and lower through holes, and the gap between the inclusions and the bottom 27 of the flower pot 26 is sealed with the same sealing material as the sealing material 17 on the lower surface of the base 14.

  Moreover, the said water level adjustment drainage tool 10 can also be used in combination with the waterproof sheet 30, as shown in FIG. An opening 31 is formed in the waterproof sheet 30, and the protrusion 15 is inserted into the opening to sandwich the periphery of the opening 31 between the base 14 and the cap 12. As the waterproof sheet 30, in addition to a synthetic resin sheet such as polyethylene and polypropylene, a woven cloth surface coated with a synthetic resin or rubber is used. This can be used for a planter or a flower pot 26 that has no bottom or is not waterproof at the bottom, and can maintain the water level H at the height of the upper end of the protrusion 15.

  4 and FIG. 5 is provided with a connecting pipe 34 in the lateral direction on the projecting portion 15 of the main body 11, and the height of the cap 12 is reduced in order to avoid interference between the cap 12 and the connecting pipe 34. In addition, the center region of the base 14 is further raised to form the contact table 35. Other parts are substantially the same as the water level adjusting drainage device 10 of FIGS. The distal end of the connecting pipe 34 is tapered to fit a drainage tube (see FIG. 8), a water stop cock, and the like, and the inside communicates with the inside of the protruding portion 15. The abutment table 35 may be hollow or solid. The height of the cap 12 is lowered by the amount of the contact table 35.

  When the water level adjusting drain 33 is used in a flower pot 26 having a drain port 28 formed in the bottom 27 as shown in FIG. 2, a water stopper such as a rubber stopper is fitted to the tip of the connecting pipe 34. Used in the same manner as 2. On the other hand, when used in a planter having a drain outlet at the corner of the bottom or at the lower end of the side instead of near the center of the bottom, one end of the drain tube is liquid-tightly fitted to the connecting pipe 34 and the other end Is used so as to be exposed to the outside from the corner or side drainage port (see FIG. 8). As the tube, a silicone rubber tube that easily maintains the sealing performance is preferable. A sheet-like sealing material may be wound around the gap between the tube 36 and the drain port. Also in this case, water or a culture solution can be stored in a container such as a flower pot until the water level H reaches the upper end of the protrusion 15.

  A plant cultivation sheet 37 shown in FIG. 6 is a combination of a water level adjusting drainage device 38 and a waterproof sheet 30. In order to facilitate molding, the water level adjusting drainage tool 38 used here separates the abutment base 35 and the connecting pipe 34 in the water level adjusting drainage tool 33 of FIGS. Yes. Therefore, the main body 11 is comprised by the base 14 and the protrusion part 15 similarly to the main body 11 of the water level adjustment drainage tool 10 of FIG.

  The contact table 35 of the intermediate member 39 has a bottomed cylindrical shape including a top surface 40 and a peripheral wall 41, and a cylindrical boss 42 is provided at the center of the top surface 40. On the inner surface of the boss 42, a female screw 43 that is screwed with the male screw 18 of the protruding portion 15 of the main body 11 is formed. The connecting pipe 34 protrudes laterally from the peripheral wall 41, and the inside thereof communicates with the inside of the contact table 35. Further, a flange 44 that abuts the upper surface of the base 12 is provided at the lower end of the peripheral wall 41.

  On the other hand, an annular groove 45 is formed on the upper surface of the base 12 of the main body 11, and a ring-shaped gasket 46 for securing a seal with the flange 43 is accommodated in the annular groove. The projecting portion 15 of the main body 11 is formed with a communication port 47 that communicates the inside with the inside of the abutment base 15.

  Further, in this water level adjusting drainage device 38, as shown in FIG. 7, the cap 12 is not provided with an inner cylinder (see reference numeral 23 in FIG. 2), and a female screw 48 is formed directly on the inner edge of the rib 24. Thereby, injection molding of synthetic resin is easier. The main body 11 of the water level adjuster 38 can have the same shape as the main body 11 of the water level adjuster / drainage 10 shown in FIGS. 1 and 2 except for the communication port 47. Therefore, only the communication port 47 may be post-processed by sharing parts. Further, the cap 12 can be shared with the cap 12 of the water level adjusting drainage device 33 of FIGS.

  The plant cultivation sheet 37 provided with the water level adjusting drainage device is obtained by sandwiching the waterproof sheet 30 between the base 12 of the main body 11 and the intermediate member 39 in the water level adjusting drainage device 38 of FIG. For example, a water stopcock 49 is fitted to the tip of the connecting pipe 34 and then spread inside a pot or planter 50 that is not waterproof as shown in FIG. Plants can be cultivated.

  In this case, the water poured into the soil 29 enters the cap 12 from between the cap 12 and the contact table 35, flows into the inside from the upper end of the projecting portion 15, and flows out from the opening 13 of the base 11 at the lower end. Therefore, the water level H can be maintained at the height of the upper end of the protrusion 15. The inside of the abutment base 15 and the inside of the protruding portion 15 are communicated with each other through a communication port 47. However, since the connection pipe 34 is closed with a water stopcock 49, the inside and the outside of the abutment base 35 are Blocked. Further, by utilizing the flexibility of the waterproof sheet 30, the water level H can be easily raised only by interposing the base 51 having an appropriate height between the base 14 and the bottom surface of the planter 49.

  On the other hand, when the tube 36 is connected to the connection pipe 34 and the opening 13 of the base 12 is closed with a water stop cock, the tube 36 can be drained. In this case, the water level H can be easily adjusted as described above. As described above, since the stop cock 48 of the connection pipe 34 and the stop cock of the opening 13 of the base 12 are not used at the same time, it is preferable that both can be used together.

  The water level adjusting drain device 38 in FIG. 6 is combined with the waterproof sheet 30 to form the plant cultivation sheet 37, but can be sold and used alone. Further, in the water level adjusting / draining device 38 of FIG. 6, the protruding portion 15 of the main body 11 and the intermediate member 39 are screwed together, but it may be simply fitted between cylindrical surfaces or prismatic surfaces. Further, in any of the embodiments, the protruding portion 15 and the cap 12 are not screwed together, and the elastic piece formed on one side can be coupled by a snap coupling that elastically engages the stepped portion formed on the other side. . Further, the cap 12 does not need to cover the entire base 14 and the intermediate member 39, and may be of a size that covers the upper end opening of the protruding portion 15 with a gap for water.
