The present invention relates to a planting panel for hydroponic cultivation and a planting panel cover that is placed over the top surface of the planting panel for hydroponic cultivation.

[Conventional technology]

One method of cultivating plants is hydroponic cultivation, which uses a culture solution instead of soil to supply the nutrients the plants need. In the above-mentioned hydroponic cultivation, a hydroponic cultivation holder (hereinafter referred to as a cultivation holder) is used to raise the seeds of the cultivation product and to hold the seeds. And this cultivation holder is
It is assembled into a planting panel for hydroponic cultivation (hereinafter referred to as a planting panel) that can stably hold a large amount on the culture solution.

Conventionally, as shown in FIG. 7, the above-mentioned planting panel has been formed into a plate shape of, for example, expanded polystyrene, and has an opening 3 for holding a cultivated product holder 30.
It has a plurality of 1a... These openings 31a
... is formed so as to communicate from the front surface to the back surface of the planting panel 31, and is connected to the cultivated product holder 30.
... are inserted until they reach the back surface of the transplanting panel 31, so that the lower part comes into contact with the culture solution 33.

[The problem that the idea aims to solve]

However, in the above-mentioned conventional planting panel 31, the weight of the grown crops 32...
1 may sink into the culture solution 33. In this case, the contact between the cultivated product holder 30... and the culture solution 33 increases, and the cultivated product holder 30...
Excess moisture causes the stems, etc. of the cultivated plants 32 to become overhumidified and deficient in oxygen.

Therefore, for example, Japanese Patent Publication No. 54-7693 discloses a planting panel 34 in which air chambers 35 are formed, as shown in FIG. Air chamber 3 above
5 increases the buoyancy of the planting panel 34 and reduces the sinking of the planting panel 34 into the culture solution 33 even if the weight of the cultivated plants 32 increases. As a result, the cultivated product holder 30... assembled in the opening 34a can hold the culture solution 33.
By maintaining constant contact with the water, excess moisture is prevented.

However, it is difficult to sufficiently prevent excess moisture in the cultivated product holders 30 even with the above-mentioned planting panels 34. That is, conventional planting panel 3
Hydroponic cultivation according to No. 1 is carried out by immersing the cultivated product holder 30 in the culture solution 33, and when there is excess water in the cultivated product holder 30, water is directly supplied from the culture solution 33. This is a major factor. This factor is due to the fact that even if the cultivation product holder 30...
Even if the contact with 3 is constant, it has the same effect, and even in hydroponic cultivation using the above-mentioned planting panel 34,
The prevention of excessive moisture in the cultivated product holders 30 has not been fundamentally solved.

In this way, in hydroponic cultivation using the above-mentioned planting panels 31 and 34, the stems of the cultivated plants 32... are likely to become overhumidified or deficient in oxygen due to the excess moisture in the cultivated product holders 30..., and the cultivated plants 32... It has become difficult to maintain a good breeding environment. Therefore, in the present invention, a planting panel for hydroponic cultivation and a planting panel that can maintain a good growing environment for the cultivated products 32 while preventing contact between the cultivated product holder 30 and the culture solution 33 are provided. It is intended to provide cover.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

The planting panel for hydroponic cultivation (hereinafter referred to as the planting panel) according to this example is as shown in FIG.
For example, it is formed into a plate shape of foamed polystyrene or the like. This planting panel 1 is formed with a plurality of openings 1a for holding cultivated product holders for hydroponic cultivation (hereinafter referred to as cultivated product holders) to be described later. As shown in FIGS. 3 and 4, these openings 1a are communicated from the front surface to the back surface of the planting panel 1, and the roots of the cultivated plants held in the cultivated product holder are exposed to the culture solution 2. Being reached.
Furthermore, holding portions 9 are formed at both longitudinal ends of each of these openings 1a. This holding part 9
As shown in FIGS. 5 and 6, it is made up of a bottom part 9a that comes into contact with the bottom of the cultivated product holder 8, and side parts 9b, 9b that come into contact with the side surfaces of the cultivated product holder 8.

As shown in FIG. 6, the bottom portion 9a is formed to have a width narrower than the width of the opening 1a, and side portions 9 are raised from both ends of the bottom portion 9a.
b, 9b are formed to be inclined on the surface of the planting panel 1 so as to have the same width as the opening 1a. Thereby, the cultivated product holder 8 is reliably held because the bottom portion is supported by the bottom surface portion 9a of the holding portion 9 and both side surfaces are supported by the side portions 9b.

In addition, the height of the bottom surface part 9a, which is the distance from the bottom surface part 9a to the back surface of the planting panel 1, is the height of the bottom surface part 9a, which is the distance from the bottom surface part 9a to the back surface of the planting panel 1, as shown in FIGS. 4 and 5. When the bottom part 9 sinks into the
The distance H is set such that a is located above the culture solution 2 and the bottom surface portion 9a and the culture solution 2 do not come into contact with each other. Thereby, the cultivated product holder 8
is formed between the cultivated product holder 8 and the culture solution 2, thereby preventing direct supply of water from the culture solution 2.

As shown in FIGS. 5 and 6, the cultivated product holder 8 held by the bottom part 9a and the side parts 9b, 9b has a support member 11 and a water-retentive structure provided on the back surface of the support member 11. The support member 11 is formed with a plurality of notches 11a through which the roots of the cultivated plant can pass and reach the culture solution 2. Moreover, as shown in FIGS. 1 and 2, this cultivated product holder 8 has an upper side surface portion 1d that comes into contact with the adjacent planting panel 1, and a culture solution 2 on all sides of the assembled planting panel 1. A lower slope portion 1b is formed to prevent the rise of the lower slope portion 1b.

The above-mentioned upper side surface portion 1d is suspended from the surface of the planting panel 1 by a predetermined length, and the lower slope portion 1b
is the planting panel 1 from this hanging lower end 1c.
It is formed so that it slopes inward until it reaches the back surface. As a result, the planting panels 1, 1 come into contact with each other only at the upper side surfaces 1d, 1d,
A space 4 is formed between the lower slope parts 1b and 1b and the culture solution 2.
is beginning to form.

The height of the lower slope part 1b, which is the distance between the lower end 1c of the upper side part 1d and the back surface of the planting panel 1, is determined by Lower end portion 1c of upper side surface portion 1d
The distance H ₁ is set to such an extent that it does not come into contact with the culture solution 2. Therefore, the planting panel 1 has a space 4 in which the rise of the culture solution 2 does not cause capillary action.
This is now being prevented.

Further, as shown in FIGS. 5 and 6, the planting panel 1 is covered with a planting panel cover 12 that promotes the growth of cultivated plants.
This planting panel cover 12 has a degree of transparency that allows light such as sunlight to pass through, for example.
It consists of a cover body 14 and a water-retentive member 15 attached to the surface of the cover body 14 facing the planting panel 1. The cover main body 14 is made of, for example, foamed polystyrene, and the water-retaining member 15 is made of, for example, non-woven fabric, cold sand, foamed polyurethane foam, or the like having water-retaining properties. In addition, although it is desirable that the above-mentioned water-retaining member 15 is attached to the cover body 14, the planting panel cover 12 is not necessarily required, and may be composed of only the cover body 14.

The weight of the planting panel cover 12 is such that the roots of the cultivated plants are not pushed up by the upward force generated when they pass through the cultivated product holder 8 and grow into the culture solution 2, and that the roots of the cultivated plants are not pushed up. The setting is such that when the cultivated product reaches the culture solution 2 and grows to a certain extent, it is pushed up by the force that stretches upward. Thereby, the growth of the cultivated product can be confirmed by checking whether or not the planting panel cover 12 is in contact with the planting panel 1.

In addition, the above-mentioned planting panel cover 12 includes protruding portions 12 that can be loosely fitted into each opening 1a of the planting panel 1.
a is integrally formed. This protrusion 12a
is formed so that when it is loosely fitted into the opening 1a, the bottom is located above the bottom of the cultivated product holder 8 in the opening 1a. Thereby, a space 13 is formed in the cultivated product holder 8 when the protrusion 12a is loosely fitted into the opening 1a.

In the above configuration, when performing hydroponic cultivation, seeds of the cultivated product are sown in the cultivated product holder 8,
This cultivated product holder 8 is connected to each opening 1 of the planting panel 1.
It is assembled into a. At this time, the cultivated product holder 8
is held in a sufficiently stable manner by having its bottom portion contact the bottom portion 9a and its both side surfaces contacting the side portions 9b, 9b. Moreover, the cultivated product holder 8 is easily set at a position at a distance H from which it does not come into contact with the culture solution 2 by contacting the bottom surface portion 9a. and,
After the planting panel cover 12 is placed on the planting panel 1 to form a space 13, the planting panel 1 is floated on the culture solution 2 to form a space 16 between the cultivated product holder 8 and the culture solution 2.

Water vapor generated by the evaporation of the culture solution 2 is generated in the above-mentioned space 16, and this water vapor passes through the notches 11a of the cultivated product holder 8, and then passes through the projections between the cultivated product holder 8 and the planting panel cover 12. It stays in the space 13 formed by the installation part 12a. This accumulated water vapor is held by the water-retaining member 15 of the planting panel cover 12 and condenses on the side wall of the cultivated product holder 8 to form water droplets.

The water droplets slide down the side walls, reach the bottom of the plant holder 8, and are retained by the water-retentive member 10 formed on the underside of the plant holder 8. As a result, the water vapor from the culture solution 2 maintains in the space 13 a humidity level that is favorable for the growth of the plant.

The roots of the cultivated plants growing in the space 13 have a property of growing toward the dark direction, and grow toward the opposite direction of the planting panel cover 12 which has slight transparency. Therefore, these roots are connected to the notches 11a and 11 of the cultivated product holder 8.
It passes through the water-retaining member 10 located below a and heads toward the culture solution 2. At this time, the above-mentioned roots come into contact with the notch 11a... or the water-retaining member 10, and are unable to sufficiently pass through the cultivated product holder 8, pushing the cultivated product upward as the roots grow. There is.

In this case, the cultivated product pushed upward comes into contact with the protrusion 12a of the planting panel cover 12.
However, the planting panel cover 12 is set to such an extent that it cannot be pushed up by the upward force generated by the growth of roots when the weight passes through the cultivated material holder 8, so it is possible to hold down the cultivated matter. It's summery. Therefore, the above roots are planted in the planting panel cover 1.
2, it is possible to sufficiently pass through the cultivated product holder 8 and reach the culture solution 2.

In the cultivated plants whose roots have reached the culture solution 2, the growth of stems and leaves is promoted. At this time, the planting panel cover 12
The weight is set to such an extent that it can be pushed up by the upward force of the cultivated plants that have grown to a certain extent.
Therefore, the growth state of the cultivated product can be confirmed by visually checking whether or not the planting panel cover 12 and the planting panel 1 are in contact with each other. Then, the planting panel cover 12 is removed from the planting panel 1 after the above confirmation, and thereafter, the cultivated products are continuously cultivated in the same cultivated product holder 8 until they grow to the shipping stage.

Moreover, the weight of the above-mentioned cultivated products increases with growth. This increase in weight increases the weight of the planting panel 1 on which the cultivated products are placed, and the planting panel 1 is sunk deeper into the culture solution 2 from the initial 2 to 3 mm. become. At this time, the cultivated product holder 8 that holds the cultivated products
is supported by the holding part 9. This holding part 9
is a distance H that is such that the height of the bottom part 9a does not come into contact with the culture solution 2 when the planting panel 1 sinks into the culture solution 2 due to the weight of the grown culture.
is set to . Therefore, the cultivated product holder 8 is
Since the plant is not immersed in the culture solution 2 during cultivation, water is not directly supplied from the culture solution 2.

In this way, when hydroponic cultivation is performed using the planting panel 1 and the planting panel cover 12 according to this embodiment, the water supply to the cultivated product holder 8 is controlled by the culture solution 2.
This is done indirectly through the space 16 by the water vapor. Therefore, the cultivated product holder 8 is prevented from being supplied with excessive moisture, and it becomes possible to maintain a good growing environment for the cultivated products.

In this example, contact between the cultivated product holder 8 and the culture solution 2 is prevented by supporting the cultivated product holder 8 on the bottom surface part 9a having a distance H, but this is not limited to this. It will not be done. That is, in the planting panel 1, the distance between the bottom of the cultivated product holder 8 assembled in the opening 1a and the water surface of the culture solution 2 is set to be larger than the distance H, and the distance between the cultivated product holder 8 and the culture solution 2 is set to be larger than the distance H. It is sufficient that a space 16 is formed between them.
