Is a hydroponic cultivation method for bulbous plants that can maintain the balance of the center of gravity by maintaining the growth of the bulbous plants.

The buoyancy support means of the bulb plant cultivating tool 10 of the present embodiment includes a buoyancy support body 16, an accommodation portion 20 for the bulb 14 provided in the buoyancy support body, and a through hole 18 for the bulb stem 15. , Locking means 1 for locking the bulb to the buoyancy support body
2 is provided. In FIG. 1, the buoyancy support body 16
Is a buoyant body that directly holds the bulbs 14 of tulips, dahlia, lilies, amaryllis, hyacinths, and other bulbous plants, and buoyantly supports on the water surface. It is a structure that can float on the surface of the water in the state of being. The buoyancy support 16 may be any structure that can float on the water surface by receiving the buoyancy of water. For example, as shown in FIG. 1, a material having a single buoyancy may be used to form a container for accommodating a bulb. It may be formed integrally or as shown in FIGS.
As shown in FIG. 5, a float member having a closed hollow portion inside may be used, or a combination of the float member and a root pressing portion having a through hole may be used.

In this embodiment, the buoyancy support body 16
Is formed of, for example, a synthetic resin foam member such as styrofoam, and as shown in FIG. 1 or 3, is formed of a single thick plate member having a rectangular shape in plan view. The buoyancy support main body 16 forms an integral hole that communicates with the through hole 18 of the stem portion of the bulb 14 and the accommodating portion 20 for accommodating and arranging the bulb so as to penetrate therethrough in the thickness direction thereof in the approximate center in plan view. It is configured by molding. In FIG. 1, when the buoyancy support body 16 is floated on the water surface, a through hole 18 is formed so as to vertically penetrate in the central portion of the thick plate member, and a housing portion 20 is formed in communication with the lower side thereof. ing.

The accommodating portion is provided in the buoyancy support body, and is arranged so that when the outer buoyancy support body is floated on the water surface for cultivation, the roots of the bulbs are directed upward and the root hairs are located in the water. As shown in FIGS. 11 and 12, basically, it is sufficient if there is a storage space that can pass through at least the rhizome of the bulb and be aligned with the hole. For example, the size may be such that only the upper half portion 50a can be accommodated,
Further, it may be a space or void having a size including the bulb main body including the lower half portion 50b. At that time, it is necessary to open the portion corresponding to the root hair portion. For example, FIG. 11 is configured as a cylindrical hole having a diameter such that the bulb can be inserted vertically with the thick plate member serving as the buoyancy support body 16 in the thickness direction. This allows the root hairs of the bulbs to be positioned on the underwater side and the rhizomes to be positioned upwards so that the bulbs can be accommodated in a state in which the upper and lower positions are determined. As described above, the housing portion 20 has only to have a size that can determine the vertical arrangement of the bulbs to be held, and therefore, the size of the entire body of the bulb is not necessarily completely housed in the housing portion 20. However, the vertical height or sectional diameter may be such that the upper half of the bulb can be accommodated.

In the embodiment, the accommodating portion 20 is composed of a recessed hole communicating with the passage hole 18 and having an opening on the root hair side of the bulb. That is, as shown in FIG. 1, the buoyancy support main body 16 is made to have a hole that is opened on the lower surface side in a state of being floated on the water surface, and the upper side thereof is recessed in a hemispherical shape or a bowl shape and is recessed upward. ing. More specifically, in the embodiment, the recessed hole of the accommodating portion is formed so as to extend downward and communicate with the through hole 18 so as to cover at least the upper half of the bulb. This makes it possible to determine the vertical arrangement of the bulbs as well as the horizontal position of the bulbs with respect to the buoyancy support body. The hole as the accommodating portion does not have to have a circular horizontal cross section, and may have, for example, a rectangular shape as shown in FIG. 12 or any other arbitrary shape. Preferably, FIG.
As shown in FIG. 5, a bottomed hole having a through hole at the bottom that opens downward is simple and inexpensive to manufacture.

The accommodating portion 20 may be formed by integrally molding a thick plate member as shown in FIGS. 1 and 11, or may be formed by connecting and combining a float member and a plate member. The buoyancy support main body or the float member may be divided into upper and lower parts, and a space such as a housing portion or a through hole may be formed in an assembled state.
