DESCRIPTION OF THE PREFERRED EMBODIMENTS The following will describe one embodiment of the present invention with reference to FIGS.

A hydroponic planting panel 1 for hydroponics (hereinafter abbreviated as planting panel 1) is made of, for example, expanded polystyrene, and as shown in the plan view of FIG.
It has a plurality of openings 3 for assembling a cultivator holder for hydroponics (hereinafter, abbreviated as cultivator holder) for holding and growing plants. Further, the planting panel 1 has the same number of lower protrusions 5 ... As the openings 3 ...

The openings 3 ... Have a fixed pitch and the planting panel 1
Are arranged in. The lower protrusions 5 are arranged on the planting panel 1 at the same pitch as the openings 3, and when the planting panel 1 is rotated 180 degrees in the plane, the position of the lower protrusions 5 is the opening before rotation. It is arranged so as to match the position of the portion 3.

An enlarged view of the opening 3 is shown in FIG. In addition, a cross-sectional view taken along the line AA of the opening 3 in FIG. 2 is shown in FIG.
Line sectional views are shown in FIG. 4, respectively.

As shown in FIG. 3, the opening 3 penetrates from the front surface to the back surface of the planting panel 1, and the root of the cultivated product held by the cultivated product holder passes through the opening 3 and becomes a culture solution. To reach.

The upper part of the opening 3 is the planting panel 1.
Although it is formed so as to be perpendicular to the front surface of the planting panel 1, the lower portion 6 of the opening 3 is formed so as to widen toward the back surface of the planting panel 1.

Further, the opening 3 is provided with holding portions 4 for holding the cultivation holders at both ends in the longitudinal direction.
As shown in FIG. 4, the holding portion 4 includes a bottom surface portion 8 that comes into contact with the bottom portion of the cultivated product holder and side surface portions 7 and 7 that come into contact with side surface portions of the cultivated product holder.

In the present embodiment, the surface of the planting panel 1 is
In order to prevent water accumulated on the surface of the planting panel 1 from flowing around the opening 3 into the culture holder after the watering after sowing, the upper protrusion 2 is provided on the outer edge of the opening 3. ing.

The lower surface of the planting panel 1 is provided with the same number of lower protrusions 5 (FIG. 2) as the openings 3 as described above. Then, as shown in FIG. 5, when the planting panels 1 are rotated by 180 degrees and alternately stacked, the lower protrusions 5 are loosely fitted in the openings 3, and the lower protrusions 5 are A gap 10 slightly larger than the diameter of the seed between the bottom of the plant and the cultivator holder 9 assembled in the opening 3.
The heights of the upper protrusion 2 and the lower protrusion 5 are set so that the

In the above structure, when hydroponics is carried out,
First, the cultivation holder 9 (FIG. 5) made of a water-retaining material such as non-woven fabric is attached to the opening 3 of the planting panel 1. That is, by fitting the cultivated product holder 9 into the opening 3, the cultivated product holder 9 is held by the side surface portion 7 (FIG. 4) and the bottom surface portion 8 of the holding portion 4.

The cultivation holder 9 thus set on the planting panel 1 is seeded. Then, water is sprinkled to cause germination. At the time of watering, excess water is scattered on the planting panel 1, but this water is blocked by the upper protrusion 2 provided on the outer edge of the opening 3, and the water is transferred to the cultivator holder 9 assembled in the opening 3. Inflow of water is blocked. Therefore, it is possible to prevent the seeds from becoming excessively humid due to the excessive inflow water and to prevent the sown seeds from moving to a position other than the predetermined position, thereby improving the germination rate.

After watering, as shown in FIG. 5, the planting panel 1
Are rotated 180 degrees and stacked alternately. As a result, the lower projection 5 of the other planting panel 1 is fitted into the opening 3 of the one planting panel 1. Then, the stacked planting panels 1 ... Are placed under appropriate temperature and humidity conditions to promote germination. At this time, since a gap 10 slightly larger than the diameter of the seed is formed between the bottom of the lower protrusion 5 and the cultivated product holder 9 assembled in the opening 3, the lower protrusion 5 is It acts as a cover soil substitute. That is, since the seeds sown in the hydroponic cultivation holder 9 assembled in the opening 3 are prevented from moving by the lower protrusion 5, the movement of the seeds due to the reaction of the growing root during germination is prevented. It is prevented, and the root is less likely to occur.

When the planting panels 1 are stacked, the upper protrusions 2 are provided on the outer edges of the openings 3 as described above, so that the cultivation planted on the surface of one planting panel 1 and the other planting panel 1 is assembled. A larger gap is created between the object holder 9 and the object holder 9. Therefore, during germination, the grown roots are less likely to hit the surface of the lower planting panel 1, and are less likely to be damaged by the stacking of the planting panels 1.

After germination, when the roots grow to some extent and enter the culture holder 9, the seeds are sufficiently held in the culture holder 9 and do not move. In this state, the stacking method of the planting panels 1 ... Is changed as shown in FIG. That is, the planting panels 1 are stacked in the same direction without being rotated. As a result, the lower protrusion 5 functions as a spacer for providing a gap between the planting panels 1, 1 and prevents the grown roots from hitting the lower planting panel 1 and being damaged.

In this state, when the seedlings are continued to grow and the seedlings grow to an appropriate size, the planting panels 1 are floated one by one on the culture solution. Then, the cultivated product absorbs nutrients from the culture solution and grows.

When the planting panel 1 is floated on the culture solution, the cultivation holder 9 is replaced for the roots whose growth condition is poor. At this time, in the planting panel 1 of the present embodiment, the lower portion 6 of the opening 3 was formed so as to widen toward the back surface of the planting panel 1, so that by pushing with a finger from the back surface, the poorly growing seedlings are held. The existing cultivated product holder 9 can be easily taken out, and replacement of the cultivated product holder 9 becomes extremely easy.

Further, even at the time of harvesting, since the lower part 6 of the opening 3 is made wide, the planting panel 1 can be easily handled by putting a finger on it, and the planting panel 1 can be easily transported. become.

Further, also in the cleaning of the planting panel 1 after harvesting, since the lower portion 6 of the opening 3 is made wide, the opening 3 can be easily cleaned from the back surface by using a brush or a shower. In particular, the vicinity of the lower portion 6 of the opening 3 where blue algae and other algae are likely to be generated can be washed very easily because it is close to the culture liquid surface.

Since the lower protrusion 5 is provided as described above, the planting panels 1 can be easily dried by stacking the planting panels 1 in the same direction after cleaning (FIG. 6).

Furthermore, since the planting panels 1 can be disinfected in a state of being stacked in the same direction, the disinfection work is simplified.

[0032]

[Effect of the Invention] The planting panel for hydroponics according to the present invention is
As described above, with the lower protrusions on the rear surface for hydroponics planting panel to allow a gap between a hydroponic planting panel when stacked planting panel hydroponics is provided, the lower The side projections have 180 hydroponics planting panels.
It is arranged so as to be loosely fitted in the opening when it is rotated alternately and stacked alternately .

As a result , when the hydroponic planting panel is placed under appropriate temperature and humidity conditions to promote germination, the roots extending from the upper hydroponic planting panel are on the lower side. Since it will be hard to hit the surface of the planting panel,
The roots are hard to ache. Moreover, during germination, the lower protrusions loosely fit into the openings, so that the lower protrusions act as cover soil substitutes for the seeds. That is, since the movement of the seed sown in the hydroponic culture holder assembled in the opening is hindered by the lower protrusion, during germination, movement of the seed due to reaction of the growing root is prevented, This has the effect of making it difficult for floating roots to occur.
