Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cultivated product holder for hydroponic cultivation that is used in combination with a planting panel floating on a culture solution in hydroponic cultivation.

[Conventional technology]

One method of cultivating plants is hydroponic cultivation, which uses a culture solution instead of soil to supply necessary components to plants. In the above-mentioned hydroponic cultivation, a cultivation product holder for hydroponic cultivation (hereinafter referred to as a cultivation product holder) is used to raise the seeds of the cultivation product and to hold the seedlings.
is used.

Generally, cultivated product holders are designed to increase water capacity by using urethane chips or rock wool with a high porosity so that sufficient nutrients can be supplied to the cultivated products.

A single seed is sown in each of the above-mentioned cultivation holders, and after the cultivation has grown to some extent, seedlings with particularly good growth are selected from among the seedlings that have firmly established roots in the cultivation holders. Ru. The selected seedlings are then transplanted to planting panels floating on a culture solution and grown until they can be shipped as products.

However, in the above-mentioned cultivated material holder, it is difficult for the cultivated seeds to be stabilized, and furthermore, once the cultivated material has grown to a certain extent, it is difficult for the operator to transplant the cultivated material from the cultivated material holder to the planting panel. There are problems such as the need for

Therefore, in order to solve the above-mentioned problems, cultivated product holders have recently been provided with a holding part having a V-shaped cross section for holding seeds of cultivated plants for germination and growth, and a bottom part of this holding part. It has been proposed to have a cutout large enough to prevent the seeds of cultivated plants from passing through (Utility Application No. 151192/1983).

That is, as shown in FIG.
It is formed into a substantially triangular prism-shaped container shape having a letter-shaped holding portion 31b.

At the bottom of this holding portion 31b, a notch 31a is provided.
As shown in Figure 9, the right end 3 in the longitudinal direction in a straight line
It is formed over the entire area from 1g to the left end 31f. Moreover, the width of the notch 31a is the width of the seed 32.
can be stably held at the bottom of the holding part, and the seeds 3
2 is set to be large enough to prevent it from falling.
And a cultivated product holder 31 having the above configuration.
has conventionally been integrally formed from polystyrene foam or the like.

As a result, the cultivated product holder 31 described above can hold the cultivated seeds 32 in a stable state, and since the cultivated product holder 31 is germinated from the beginning with the cultivated product holder 31 assembled to the planting panel, the seeds 32 will germinate. There is no longer a need to transplant the seed 32 into a planting panel.

[The problem that the idea attempts to solve]

However, in the cultivated product holder 31 described above, there is a risk that water droplets may accumulate at the bottom of the cultivated product holder 31, and the seeds 32 may have difficulty germinating due to the influence of the water droplets, or may not germinate and rot.

That is, when sowing the seeds 32 in the cultivated product holder 31, the seeds 32 are soaked in water for about 12 hours in advance, and then the surface water is drained etc. so that the seeds 32 can easily absorb oxygen. is removed.

However, the cultivated product holder 31 described above is made of a material that does not retain water, such as expanded polystyrene. Further, as shown in FIG. 8, this cultivated product holder 31 has a substantially V-shaped cross section, and the width of the notch 31a is smaller than the diameter of the seed 32.

Therefore, when water vapor generated during cultivation condenses on the side wall 31d of the cultivated product holder 31 and becomes water droplets,
These water droplets flow down toward the bottom of the cultivated product holder 31, are stopped by the notch 31a, and accumulate at the bottom. As a result, the cultivated product holder 3
When the seeds 32 held at the bottom of the seed 1 are directly immersed in the water droplets, it becomes difficult for them to absorb oxygen, making it difficult for them to germinate, or they may not germinate and rot.

Therefore, the purpose of the present invention is to provide a cultivated product holder for hydroponic cultivation in which the seeds 32 are not affected by harmful effects such as excessive humidity during cultivation and can always provide a good environment for seed cultivation. It is said that

[Means to solve the problem]

In order to solve the above problem, the cultivated product holder for hydroponic cultivation according to the invention of claim 1 is assembled into the opening of a planting panel that is floated on a culture solution, and is used for hydroponic cultivation to grow cultivated products. A cultivated product holder includes a support member having a notch formed in a width larger than the diameter of a seed, and a support member provided on the lower surface of the support member so as to cover the notch, so that roots of young seedlings can pass through. It is characterized by comprising a water-retentive member formed of a porous material in which continuous pores are formed and communicated from the front surface to the back surface.

In order to solve the above problem, the cultivated product holder for hydroponic cultivation according to the invention of claim 2 is used for hydroponic cultivation for growing cultivated products, which is assembled into the opening of a planting panel that is floated on a culture solution. A cultivated product holder includes a support member having a notch formed in a width larger than the diameter of a seed, and a support member provided on the lower surface of the support member so as to cover the notch, so that roots of young seedlings can pass through. and a water-retaining member formed of a porous material in which continuous pores are formed from the front surface to the back surface, and the support member is bendable so that the water-retaining member located below the notch becomes flat. It is characterized by being

[Effect]

According to the structures of claims 1 and 2, in hydroponic cultivation, after the seeds are put into the hydroponic cultivation holder, the hydroponic cultivation holder is inserted into the opening of the planting panel. This is done by assembling it into a cell and floating it on a culture solution.

At this time, the water vapor of the culture solution passes through the notch, condenses on the surface of the support member, becomes water droplets, and then flows down into the notch. These water droplets are absorbed by the water-retaining member because the width of the notch is larger than the diameter of the seed and the water-retaining member located below the notch is made of a porous material. become. The absorbed water droplets are retained in the continuous pores of the porous body.

On the other hand, if excessive water is absorbed to the extent that it cannot be retained by the continuous pores, the absorbed water droplets will drip from the water-retaining member into the culture solution. Therefore, the water retaining member always maintains an appropriate amount of water. Further, since the cutout portion has a width larger than the diameter of the seeds, the seeds that have been thrown in come into contact with the water-retaining member. This makes it possible for seeds to sufficiently absorb the moisture required for growth from the above-mentioned water-retaining member, and since water droplets do not remain in the water-retaining member, the seeds are not affected by negative effects such as overhumidity during cultivation. Never.

Furthermore, when the cultivated product holder for hydroponic cultivation according to claim 2 is bent, the water retaining member located below the notch becomes flat. When this flattened water-retaining member is assembled into the opening of the planting panel, it becomes approximately parallel to the water surface of the culture solution.

Therefore, the roots that have passed through the water-retaining member will grow directly below the shortest distance toward the culture solution.
It becomes possible to complete the growth of cultivated products in a short period of time.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 7.

As shown in FIGS. 1 and 2, the cultivated product holder 2 for hydroponic cultivation (hereinafter referred to as the cultivated product holder 2) according to the present invention has a support panel 4 that is a supporting member.
have. This support panel 4 is made of, for example, a foamed polystyrene sheet, and is formed into a rectangular flat plate shape. Further, in the center of the support panel 4, three notches 4a are formed in the longitudinal direction of the cultivated product holder 2, through which roots grown from seeds pass so as to reach the culture solution.

These notches 4a... are formed all at once by pressing during the processing stage along with the fold lines 7, which will be described later, and the width of the notches 4a... is larger than the diameter of the seed. It is formed to a certain degree.

Note that the number of cutouts 4a is not limited to three. That is, the number of notches 4a may be one, two, or three or more, as long as the cultivated product holder 2 has enough strength to maintain its shape while growing seeds. Also good.

The support panel 4 also includes crease lines 7 that allow the cultivated product holder 2 to be easily folded into a predetermined shape.
is formed in the longitudinal direction. These fold lines 7
... are formed at positions that substantially coincide with both widthwise ends of the notches 4a. Thereby, when the cultivated product holder 2 is bent along the fold lines 7 and formed into a predetermined shape, the water-retaining member 12 (described below) located below the notch 4a is flattened. It's summery. Then, this flat water retaining member 1
2, as shown in FIG. 4, when the cultivated product holder 2 is assembled into the opening 9a of the planting panel 9,
The water retaining member 12 and the water surface of the culture solution 10 are made to be approximately parallel to each other.

Support panel 4 in which the above-mentioned notches 4a... are formed
As shown in FIG. 3, a water-retaining member 12 capable of holding seeds is provided on the entire lower surface of the container. This water-retaining member 12 is made of a porous body made of a resin having a large number of continuous pores, such as foamed polyurethane foam. As shown in FIG. 4, the diameters of these continuous holes are such that they allow the roots of the young seedlings 13 to pass through, and when the roots that have reached the culture solution 10 are pulled by the flowing culture solution 10, they is set to such an extent that it does not fall out of the continuous hole. The water retaining member 12 made of this porous material has a notch 4
Water from a is absorbed and retained in the water retaining member 12, and when the retained water becomes excessive, it is dripped into the culture solution 10.

Note that this water-retaining member 12 is not limited to a porous material made of a resin such as the above-mentioned foamed polyurethane foam, but may be made of a non-woven material, for example, as long as it has a large number of continuous pores that communicate from the front surface to the back surface. It may also be a porous body made of fibers such as chilli sand. Further, this porous body may have open cells regardless of whether or not it has moisture retaining properties. Further, the water-retaining member 12 does not need to be provided on the entire surface of the support panel 4, and may be provided with a size that can close the notches 4a.

In the above configuration, when using the cultivated product holder 2, as shown in FIG. 1, the cultivated product holder 2 is first bent in the A direction and the B direction along the fold lines 7. As a result, the cultivated product holder 2
As shown in FIG. 4, the notch 4a sandwiched between the fold lines 7 and 7 and the water-retaining member 12 located below the notch 4a are flat.

Next, seeds that have been immersed in the culture solution 10 for about 12 hours and sufficiently contain the culture solution 10 are placed in the bent cultivated product holder 2. The inserted seeds are held by the flat water-retaining member 12 because the width of the notch 4a is larger than the width of the seeds. After this, the above-mentioned cultivated product holder 2
After being assembled into the opening 9a formed in the planting panel 9, the culture solution 1 is placed together with the planting panel 9.
It floats to 0.

Further, this cultivated product holder 2 is covered from above with a cover sheet 6 having water-retaining properties so as to provide sufficient humidity for seeds to grow. Note that this cover sheet 6 is made of, for example, a water-retaining resin such as polyvinyl alcohol, a thick nonwoven fabric, or paper such as wadding paper.

Next, when the cover sheet 6 is covered and the cultivation environment is prepared, the space 11 formed between the cultivated product holder 2 and the cover sheet 6 is filled with a culture solution 10.
More evaporated water vapor enters through the notch 4a. This water vapor increases the humidity in the space 11, and the seeds are grown in a high humidity atmosphere.

Furthermore, as the humidity within the space 11 increases, water vapor condenses into water droplets on the surface of the support panel 4 facing the space 11. These water droplets flow down into the notch 4a located at the bottom of the support panel 4. Since the width of the notch 4a is set larger than the diameter of the seed, the water droplets that flow down do not stay in the notch 4a and are absorbed by the water-retaining member 12 provided below the notch 4a. . The absorbed water droplets are held by surface tension in the many continuous pores of the water-retaining member 12, and the seeds that come into contact with the water-retaining member 12 absorb them as water necessary for growth.

On the other hand, if a large amount of water droplets flow down to the notch 4a and the water retention amount of the water retention member 12 becomes excessive, the water droplets will flow through the water retention member 12 into the culture solution 10.
is dripped on. As a result, the water retaining member 12
It becomes possible to maintain an appropriate amount of water retention at all times, and the seeds placed on the water retention member 12 are grown in a favorable environment that is not affected by adverse effects such as excessive humidity.

Moreover, the roots of the seedlings 13 penetrate through the water-retaining member 12 and grow toward the culture solution 10. At this time, since the water-retaining member 12 located below the notch 4a has a flat shape substantially parallel to the water surface of the culture solution 10, it grows directly below, which is the shortest distance to the culture solution 10. Thereby, the roots of the seedlings 13 reach the culture solution 10 in the shortest possible time, so that the growth of the seedlings 13 is completed in a short time.

Incidentally, the fold line 7 according to this embodiment is the notch 4a.
Although it is formed at a position that substantially coincides with both ends in the width direction of..., it is not limited thereto. That is,
As shown in FIG. 5, the fold lines 7...
It may be formed at a position that coincides with the center portion in the width direction. In this case, as shown in FIG. 6, since the cultivated product holder 2 has a substantially V-shaped cross section, it becomes possible to sufficiently hold the seeds on both end surfaces of the water-retaining member 12.

Further, the fold lines 7 may be formed at both ends and at the center of the notch 4a in the width direction. In this case, depending on the type of seed and usage environment, the notch 4
The user can arbitrarily select whether the cross section of a is flat or V-shaped.

Furthermore, the fold lines 7 do not need to be formed on the support panel 4. In this case, as shown in FIG. 7, the cross section is bent into a U-shape, and the cultivated product holder 2
When assembled, the cultivated product holder 2 and the planting panel 9 are sufficiently held by the elastic recovery force of the cultivated product holder 2. Thereby, the cultivated product holder 2 has the fold line 7 shown in FIG. 1 on the support panel 4.
Since the step of forming is no longer necessary, it is possible to reduce costs.
