Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention relates to a simple hydroponic cultivation device,
More specifically, the present invention relates to a cultivation device for simply cultivating vegetables and other plants at home instead of soil cultivation.

[0002]

BACKGROUND OF THE INVENTION Generally, residential land is small, and it is almost impossible to carry out planting and growing vegetables in plants such as condominiums and apartments, and growing vegetables and plants.

[0003]

The conventional hydroponic cultivation equipment used for institutional horticulture is a large-scale vegetable factory, and amateurs cannot enjoy vegetable cultivation and horticulture as hobbies.

In view of the above problems, the present invention can easily grow plants not only indoors but also in any place without promoting soil, and promote their growth. It is intended to provide a domestic hydroponic cultivation device capable of performing the above.

[0005]

SUMMARY OF THE INVENTION A simple hydroponic cultivation apparatus of the present invention is a container whose upper part is open, a culture solution is contained in the container, and the open part of the container is closed to close seeds of plants. Alternatively, it comprises a cultivation bed adapted to hold seedlings and a device for supplying air to the culture solution.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, a hydroponic cultivation apparatus 10 of the present invention comprises a water tank 12 whose upper side is open. The aquarium 12 is made of, for example, plastic or glass,
It is preferably transparent or translucent.

A cultivation bed 14 is fixed to the aquarium 12 so as to be detachable at a predetermined position. Cultivation bed 1 in aquarium 12
A shoulder 16 may be provided on the inner wall of the aquarium 12 to fix the 4. However, other means, such as the cultivation bed 14 can be attached from the top of the aquarium, if desired, using suitable hanging hardware (not shown).

The cultivating bed 14 is, for example, a plate body such as styrofoam, and is used for supplying water to an appropriate position in order to supply or replenish a desired amount of water and culture solution in the aquarium 12 to which the cultivating bed 14 is attached. An opening 18 is provided.
It goes without saying that a dedicated water supply pump can be used to supply water to the aquarium 12.

A drain cock 20 may be provided at the bottom of the water tank 12 in order to drain the water in the water tank 12 as needed.

A plurality of openings 22 are provided on the surface of the cultivation bed 14 at predetermined intervals. These openings 22
Is preferably frusto-conical, and a planting member or germination container 24 for arranging plant seeds or seedlings is attached.

As the planting member, in addition to fibrous substances such as cotton and water moss, commercially available trade name "Oasis" obtained by powdering sugar cane powder and solidifying it can be used.

As the germination container 24, as shown in FIG. 2, the bottom portion 2 of the funnel-shaped peripheral wall made of a water-resistant material, such as plastic, which is dimensioned to fit into the opening 22.
It is possible to make a cup-shaped product by closing the 6 with a non-woven fabric or the like.

According to the present invention, a cartridge 28 for activating the water in the water tank into active calcium is provided at the bottom of the water tank 12.
Can be placed. The cartridge 28 is formed by enclosing, for example, a reef-building coral (coral calcium), a shell, a bone meal, and a substance containing calcium in a synthetic resin net or a non-woven bag.

An air pump device 30 is attached to the water tank 12, and its output side is jetted from the bottom of the water tank 12 through a conduit 32 so that the water in the water tank 12 can be aerated.

The end of the conduit 32 may be attached to one end of the cartridge 28. Also, the aquarium 12
A magnet 32 is preferably located at the bottom of the aquarium or enclosed within the cartridge 28 to magnetize the water therein.

[0016] Depending on the kind of plant to be cultivated, there is a thing which dislikes the root being submerged in water. In order to avoid this, without directly supplying water into the water tank 12, a liquid obtained by adding appropriate fertilizer or the like to the alkalized water is mixed with the pressurized air as an air-fuel mixture, and the water tank 12 is obtained by a means known per se.
It is also possible to atomize and inject it into a space below the cultivation bed 14 attached to.

According to the present invention, by arranging the pillar assembly 34 above the cultivation bed 14 of the aquarium 12, it is possible to help hold the stem of the growing plant. It is also possible to appropriately irradiate the cultivation bed 14 with a light beam, and a cover (not shown) made of transparent plastic or the like is provided above the aquarium 12 to allow air to flow. If loaded, the growth of plants can be further promoted.

[0018]

Since the apparatus for hydroponic cultivation of the present invention is constructed as described in detail above, the cultivation bed 14 of the aquarium 12 is fixed, and water and a culture solution are supplied into the aquarium 12. Then, a planting member is attached to the opening 22 of the cultivation bed 14, and plant seeds are placed on this member. Also,
When the cup-shaped germination container 24 is used, after putting cotton or water moss in the germination container 24, plant seeds are arranged or seedlings or bulbs are planted.

The water tank 12 thus constructed can be arranged at a desired place regardless of whether it is inside or outside the room. When the water tank 12 is transparent, the inside of the water tank can be constantly monitored. It is possible to fully observe from the germination of seeds to the growth of roots. When it is necessary to avoid exposing the roots of plants to direct sunlight, the aquarium 12 can be made semitransparent, or the transparent aquarium can be covered with a suitable sheet or the like.

By operating the air pump device 30 provided in association with the water tank 12, the water in the water tank 12 is supplemented with oxygen, and the substance containing calcium contained in the cartridge 28 causes water to be supplied. It is activated and magnetized by the action of the magnet 32, so that the growth of plants can be promoted.

Since the apparatus 10 for hydroponic cultivation of the present invention can be arranged in any place without using soil, it can be used as an indoor accessory for cultivating flowers and the like or for vegetables regardless of the four seasons. Can be cultivated, and moreover, the cultivation of these plants can be enjoyed.
