Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydroponic cultivation apparatus, and more particularly to a hydroponic cultivation apparatus which has a simple structure and is easy to manage and which is optimum for appreciation.

[0002]

2. Description of the Related Art A plant grows with soil as a medium by nature's bounty, and this soil has various conditions suitable for plant growth as described below. That is, (1) a solid medium that supports plants. (2) There is a proper gap inside,
Roots are easy to grow. (3) Providing proper moisture and dryness to the roots along with the natural environment. (4) Rich in nutrients required for plant growth.

[0003] However, soil cultivation causes soiling during operation, and it is necessary to pay particular attention to indoor cultivation. In order to eliminate pathogens in the medium, a regular pesticide is used. There is a problem that spraying is necessary and the chemicals used for it also lead to environmental pollution.

In order to solve such a problem, many hydroponic cultivation techniques have been devised which satisfy the above-mentioned necessary elements (1) to (4). That is, (a) rock wool or artificial brick is used as a solid medium for supporting plants. (B) Voids are provided between the culture media so as not to inhibit root elongation. (C) The medium should have a water-retentive structure so that proper drying and humidity can be obtained. (D) A circulation device is provided to purify and enrich the culture solution.

[0005]

[Problems to be Solved by the Invention] In the conventional hydroponic cultivation techniques as described above, the plant obtains nutrition from the stored culture solution, but in order to purify or enrich the culture solution, Circulation equipment must be provided. As a result, while the peripheral devices interfere with the viewing and impair the aesthetics, the conventional artificial medium accumulates dirt in the pores, which leads to deterioration of water quality unless it is frequently maintained or replaced. There is a problem.

[0006]

The present invention has been made to solve various problems of the conventional hydroponic cultivation apparatus as described above, and has a moisturizing property and does not accumulate dirt. By using an artificial medium, the purpose is to provide a sanitary product that does not need pesticides and is easy to manage. A hydroponic cultivation device characterized by comprising a ceramic ball for a medium to be spread over and a culture solution to be injected into the container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the embodiments shown in the drawings. In FIG. 1, reference numeral 1 denotes a container made of glass, ceramics, synthetic resin or the like. The holes are not formed. Reference numeral 2 denotes a water level gauge, which is installed in the container 1, particularly when the container 1 is made of an opaque material, or when the container 1 is covered with an opaque cover, as will be described later. This is to allow the quantity to be confirmed from the outside.

3 is a ceramic ball used as a medium instead of soil, and 4 is a culture solution. The ceramic balls 3 are particles of an appropriate size produced by baking clay at a high temperature, and are characterized by being a hard and porous substance having a large number of fine pores inside.
Therefore, since this ceramic ball 3 has a moisture retaining property, it does not dry rapidly, and if it is regularly irrigated as in soil cultivation, proper drying and moisture can be obtained, and the plant may cause root rot and the like. Can grow without.

Further, when the ceramic balls 3 are stacked, an appropriate gap is formed, so that the roots of plants can grow through the gap. And since it is baked at high temperature in the manufacturing stage and sterilized, it is difficult for pathogenic bacteria to propagate, and the pores are fine and hard, so there is little dirt,
Even if it should be washed, it can be easily done without destroying its shape. Incidentally, reference numeral 5 in the figure denotes an opaque sheet cover for blocking light.

Next, in order to explain the method of using the hydroponic cultivation apparatus according to the present invention, ceramic balls 3 are spread in a container 1 of an appropriate size, and a culture solution 4 is further injected to irrigate the ceramic balls 3. I'll do it. Since the ceramic balls 3 have a moisturizing property due to the irrigation of the culture solution 4,
It becomes moist like soil as a whole. In this case, the water level meter 2 can be used to confirm the amount of irrigation water from the outside.

Then, plants 6 are planted in the spread ceramic balls 3 so that their roots 6A are immersed in the culture solution 4. By keeping this state,
Since the root 6A of the plant 6 extends from the gap between the ceramic balls 3 and 3, it can grow without inhibiting the growth of the root 6A. Similarly, in the case of cut flowers and bulbs, it is possible to grow by inserting the roots and stems into positions capable of absorbing water.

[0012] Further, by periodically drying and irrigating with the culture solution 4, generation of algae in the culture solution 4 and root rot can be suppressed, and planting can be carried out for a long period of time. Since algae are likely to be generated particularly when the light irradiation is strong, it is also effective to cover the outside of the container 1 with an opaque sheet cover 5 so as to block the light so as to suppress the growth of algae.

If the ceramic balls 3 become contaminated as a result of long-term use, they are taken out of the container 1 and washed with water. In this case, since the ceramic balls 3 are not deformed or deteriorated, they can be reused. .

[0014]

As described above, the hydroponic cultivation apparatus according to the present invention comprises a container having no water supply / drainage hole at the bottom, ceramic balls for a medium to be spread in the container, and a culture solution to be injected into the container. (1) Since the ceramic balls are hard, they are less contaminated, and can be easily cleaned even if they should be washed, and their shapes are not destroyed. Therefore, it can be reused, the plant can be firmly fixed even when it is used, and it is easy to handle without being soiled during work such as soil. (2) Since the ceramic balls are fired in the manufacturing process, no pathogenic bacteria adhere to them, and cultivation treatment such as disinfection during use is unnecessary, and management is easy. (3) The planting is easy to handle because it requires only regular irrigation of the culture broth, but the quality of the water is good for a long time without the need for a purification / circulation system, which may impair the aesthetics. Absent. (4) Since the holes of the ceramic balls are fine and dense, they have moisture retention and can be planted for a long time. Also, by installing a water level gauge inside the container, the amount of irrigation water can be confirmed from the outside regardless of the material of the container, and management is easy.
There are various effects such as.
