Description

[Detailed Description of the Invention] This invention relates to an apparatus for cultivating plants hydroponically while floating on the water surface of a pond, aquarium, or the like.

Conventionally known hydroponic devices of this kind include, for example, donut-shaped devices that are formed on a peripheral floating body and have a funnel-shaped hole in the center that narrows downward to support the bulbs. , this plant is limited to bulbs, and
Since the holding height of the plant is constant, there is a disadvantage that as the plant grows, the stomata in the stem part necessary for respiration of the plant become submerged, hindering its growth.

This invention eliminates the above-mentioned drawbacks and also protects plants from the outside so that they can grow adequately.Explanation of the embodiment of this invention with reference to the drawings is as shown in Figures 1 and 2. In addition, an inner frame-shaped receiving net 2 is mounted on the upper surface of one heating container-like member 1 which has an open top, and a ring-shaped floating body 3 made separately on the surface is slid or movable up and down. It is formed by fitting as shown.

The heating container-like member 1 is integrally made of hard synthetic resin or the like, and has an upper edge formed into an outwardly protruding collar portion 4, and has a plurality of vertical ridges 5 on the surface, four in the drawing. , and a through hole 6 is provided on the surface or the bottom surface.

The receiving net 2 has a frame body 7 covered with a fine net body 8 made of metal or synthetic resin, and the frame body 7 can be fixed by being engaged with the top edge of the heating container-like member 1. There is.

Incidentally, the warm container-like member 1 can also be fixed in advance to the frame body 7 integrally or by placing it in place.

In Figures 1 and 2, the receiving net 2 is shown as having a structure in which the entire surface is used as a net surface for cultivating plants from seeds, but the receiving net 2 is
As shown in the figure, the bulb receiving hole 9 may be formed by opening the center portion.

Although the floating body 3 is shown as a ring-shaped body made of styrene foam or the like in FIG. 2, it may be a hollow floating body made of rubber or the like.

This device has the above-mentioned structure, and after placing the required plant seeds or bulbs on the receiving net 2 with the floating body 3 fitted so as to reach the brim 4, the heating container-like member 1 is placed on the water surface. When this happens, water enters through the through holes 6 and heats the warm container-like member 1.
sinks, and becomes stable with only the upper part exposed to the water surface by the floating body 3.

In this way, a large number of roots pass through the mesh of the net body 8 of the receiving net 2 and grow and hang down into the warm container-like member 1, but since these roots are inside the warm container-like member 1, fish in the water, Damage caused by insects etc. can be prevented.

Furthermore, by moving the floating body 3 downward little by little in accordance with the growth of these roots, it is possible to raise the position of the plant and prevent excessive soaking of the roots and submergence of the stomata described above. Vertical ridges 5 are provided on the circumferential surface of the heating container-like member 1.
... protrudes, and the floating body 3 is press-fitted so that these ridges 5 ... bite into the floating body 3, so there is no risk of sliding due to its own weight even if viscous water scale is resistant to adhesion. It has many advantages, such as being able to always maintain the required net surface height, that is, the required height of the plants.
