  Hydroculture, that is, hydroponics, is gradually spreading in the home, and there are relatively increasing opportunities to see dedicated kits at home centers and the like. Such hydroponics can be seen in a wide variety from leafy vegetables such as lettuce, vegetables and fruits such as cherry tomatoes and strawberries to relatively small mini foliage plants. However, conventional hydroculture requires a special culture solution and a special case, etc., making it possible to make hydroponics easily and stably using existing aquariums and water lily pots. There is no known plant growing tray for hydroculture.

  The present invention is an invention made in view of the above-described problems, and proposes a plant cultivation tray for hydroculture that can be easily and stably hydroponically cultivated using an existing aquarium, water lily pot, etc. The purpose is to do.

  The plant cultivation tray for hydroculture of the present invention is a plant cultivation tray for hydroculture that floats on the water and holds plants, and is arranged on the outermost periphery continuously and integrally with a convex first air reservoir, Between the first air reservoir and the pot portion, the pot portion that is disposed inside the first air reservoir and stores the plant holding member for holding the plant, and formed around the pot portion. And a convex second air reservoir.

  Utilizing existing aquariums and water lily pots, it is possible to realize a plant cultivation tray for hydroculture that enables easy and stable hydroponics.

It is the top view which observed the outline of the shape of the plant growth tray for hydroculture illustrated in this embodiment explained by an embodiment from the upper surface. It is the figure which observed the A-A 'cross section of the plant growth tray for hydroculture shown in FIG. 1 from the side. It is the figure which observed the B-B 'cross section of the plant cultivation tray for hydroculture shown in FIG. 1 from the side perpendicular to FIG. (A) is a conceptual cross-sectional view illustrating a state in which a plant is planted in a pot, and (b) is a cross-section of a connector used when two hydroculture plant growing trays are connected and used. FIG.

  The plant cultivation tray for hydroculture exemplified in the present embodiment floats on the surface of the aquarium where ornamental fish are kept in the home, and the ornamental fish are raised as they are, while the ornamental plants and edible leafy vegetables are on the surface of the water. Can be hydroponically cultivated.

  Hydroponically grown vegetables, etc. can absorb nutrients from the water that the ornamental fish swims, and are excrement of the ornamental fish, which are harmful to fish, such as nitrogen, carbon dioxide, ammonia, nitrate, nitrite Etc. are absorbed from roots by vegetables as nutrients.

  As a result, a circulation cycle close to a natural cycle can be easily realized in a domestic aquarium, and long-term water change is not required. In addition, since the lighting for appreciation fish becomes light that promotes the growth of vegetables and the like as it is, it is not necessary to provide a separate light irradiation device. The plant cultivation tray for hydroculture formed of a transparent material appropriately introduces light into the water of the aquarium, and also forms an appropriate shade by leaves and leaves of houseplants.

  Therefore, the hiding place of ornamental fish is provided and it is suitable also for ornamental fish. Of course, even without preparing a dedicated culture solution, the abundance of nutrients is sufficiently supplemented to the foliage plants by feeding and excretion of the aquarium fish. That is, the plant cultivation tray for hydroculture exemplified in the present embodiment exemplified in the present embodiment is more environmentally friendly and enables hydroponics in a state closer to nature than the conventional hydroponics. It can be said that it is excellent.

The air hole 1500 appropriately adjusts the amount of air stored in the second air reservoir 1100 or the central portion of the hydroculture plant growth tray 1000 in accordance with the amount of subsidence from the water surface of the hydroculture plant growth tray 1000. It has the function to do.

  The air hole 1500 also has a function of ventilating air stored in the second air reservoir 1100 and the central part of the plant growing tray 1000 for hydroculture and supplying fresh air. Thereby, even if the plant growing tray 1000 for hydroculture covers a large part of the water surface, it is possible to effectively prevent the ornamental fish and the like from lacking oxygen.

  In addition, the amount of air is appropriately adjusted from the air holes 1500 even when the weight of the plant grows due to plant growth and the amount of submerged plant cultivation tray 1000 for hydroculture sinks more than in the setting. Therefore, it is possible to float on the water surface stably without becoming unstable.

  In addition, the amount of air is appropriately adjusted from the air holes 1500 even when the weight of the leafy vegetable is reduced due to cutting of leafy vegetables and the amount of submersion of the plant growing tray 1000 for hydroculture submerged in the water is less than that during setting. By doing so, it is possible to float on the water surface stably without becoming unstable.

  In addition, the plant growing tray 1000 for hydroculture can also be formed, for example, by forming a polypropylene sheet by hot pressing or the like. Moreover, in FIG. 1 etc., although the structure provided with two bowl 1200 in parallel is illustrated, it is not limited to this, Arbitrary number of bowls of arbitrary magnitude | sizes can be provided.

  FIG. 4A is a conceptual cross-sectional view illustrating and explaining a state where a plant is planted in the pot 1200. As can be understood from FIG. 4A, a foam member 4800 such as a sponge is disposed on the inner wall of the pot 1200, and a fired solidified porous clay such as a hydroball or the like (generically referred to as a plant holding member as appropriate). Is filled with an appropriate amount.

  The foaming member 4800 has a function of appropriately holding a plant holding member such as a hydroball or maintaining its shape, and the root of the plant 4900 extends to the inside thereof so that the plant 4900 is supported more firmly and reliably. Can help.

  In addition, since the foam member 4800 is rich in flexibility, the roots can be stretched and stretched without damaging the roots, thereby helping to absorb nutrients. The foam member 4800 is excellent in moisture retention and transmission, and transmits a proper amount of moisture from the lower part immersed in water to the upper part in the air to be located on the water surface. In order not to be extremely dried, appropriate moisture can be given.

  Further, as can be understood from FIG. 4A, the further extended root can extend downward from the drain hole 1300 into the water.

  FIG. 4B is a diagram schematically illustrating a cross section of a connector 4300 used when two hydroculture plant growing trays 1000 (1) and 1000 (2) are connected and used. When two hydroculture plant growth trays 1000 (1) and 1000 (2) are used in a connected manner, the male hooks 1400 (1) and 1400 (2) shown in FIG. The female hooks 1400 (3) and 1400 (4) may be formed in advance, and any number may be connected and used.

  Moreover, as shown in FIG.4 (b), the lower edge part of the plant growing trays 1000 (1) and 1000 (2) for hydrocultures is formed in the shape of a slightly swollen ball | bowl, and the coupling tool 4300 fitted to this is formed.
