Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a hydroponic cultivation device, and in particular to a new hydroponic cultivation device in which a holder, which is a seed growing bed, is attached to a float-type main body. It is.

(Prior art) Conventional hydroponic cultivators have a structure in which a seed cultivation bed is fixed in a water tank, so it is necessary to constantly fill the tank with a certain amount of water, and fluctuations in the water level are not favorable for seed cultivation. Therefore, its management is difficult. As a result, there were problems such as quality loss due to fluctuations in the water level and time-consuming management.

(Technical Issues) Therefore, the present invention provides a float-type hydroponic culture device that does not have any effect on germination or seedling growth due to a decrease or increase in water level, and can perform ideal cultivation simply by supplying water periodically. It is.

(Technical Means) Its purpose is to include a float body 1 which is made of synthetic resin foam that floats on water and is formed into a frame shape having sections 3 that divide the areas where seeds are to be sown, and a net 5 is stretched on the underside of the float body 1; A second float 4 has a planar shape substantially the same as the float main body 1 and has a net 5 stretched on its lower surface, and when the second float 4 is stacked under the float main body 1, there is a gap between the upper and lower nets 5, 5. A holder 2 for sowing seeds of cultivated plants, which is held between
and the superimposed float main body 1 and second float 4
This is achieved by a structure consisting of a coupling means 9 that engages with the frame portion of and integrates the two.

The float main body 1 is a means for floating seeds or growing plants on the water surface and always keeping them in a fixed position by following fluctuations in water level, and the holder 2 is a means for properly immersing them in water from seeds to growing plants. be.

Therefore, the float main body 1 needs to have a specific gravity less than 1 so that it does not corrode in water or is harmless to the growth of plants even if it corrodes, and the holder 2 needs to have a specific gravity that is less than 1 so that roots can pass through it and support the plants without hindering the growth. Formed by the material to be fixed.

(Function) Since the float main body 1 floats on water and moves up and down according to changes in water level, seeds etc. will not be covered with water even if too much water is added, roots will not be exposed even if there is little water, and plants will always be protected. A system has been established to supply adequate moisture,
Since a holder 2 is attached to it, seeds and growing plants will not be separated from the water.

(Example) The float main body 1 in the illustrated example is formed into a rectangular partition frame shape from polystyrene foam,
Section 3 is provided between partitions 6. The holding body 2 is
The floor section 7 of the second float 4 is formed to have the same planar shape as the float main body 1, and is made of cotton-like material made of vegetable fiber or other water-absorbing material. The holding body 2 is sandwiched between nets 5 and 8 stretched on the lower surfaces of the main float 1 and the second float 4, respectively, thereby suppressing the deformation of the holding body 2 due to root growth and keeping the plants at a suitable level. can be fixed to. These nets 5 and 8 are also made of a water-absorbing material like the holder 2, and improve water retention.

The second float 4 only needs to have a specific gravity that allows it to float on water without sinking, and is integrated with the main body 1 of the float by a coupling means 9 such as a U-shaped frame. Therefore, the holder 2 is detachable from the float main body 1 and can be replaced with the second float or the holder alone, and when floating on the water surface, the water surface is near the boundary between the float main body 1 and the second float 4. Set it to come.

Furthermore, FIG. 3 shows a hydroponic cultivation container 10 suitable for using the above-mentioned hydroponic cultivation device. In the figure, 11 is a water level mark formed on the inner surface of the container 10 at the time of sowing seeds, and 12
1 is a transparent cover covering the opening of the container 10, 13 is a hydroponic plant, 14 is its root, and 15 is a water surface. The water level mark 11 also serves as a mounting groove for a lid 16 that holds down the upper surface of the hydroponic float main body 1 and immerses it to a certain depth, so if necessary, it is preferable to immerse the seeds in water after sowing until germination.

Therefore, the second float 4 having the float main body 1 and the holder 2 is connected by a connecting means 9 such as a connecting frame, seeds are sown in the floating compartment 3 on the water surface, the seeds are soaked if necessary, and then periodically Just replenish water.

(Effects) As described above, according to the present invention, the float main body 1 to which the seed sowing holder 2 is attached and the second float 4 are floated on water, and the net 5 of both floats is
The holding body 2 sandwiched between the holding body 2 makes sure that the seeds sown there come into contact with the water despite fluctuations in the water level to promote germination, and during the growing process, the roots of the plants are held down by the upper and lower nets 5 and 5 to stabilize the plant. Hydroponic cultivation can be carried out. Therefore, there is no problem of water not being supplied to the plants or flooding of the plants even if overwatered, which makes water management in hydroponic cultivation much easier and has the effect of streamlining cultivation. be.
