Description

  The present invention relates to a hydroponic cultivation tray that is provided in a nutrient solution tank of a hydroponic cultivation apparatus and grows plants with the nutrient solution.

In recent years, hydroponics that grows plants for cultivation using nutrient solution without using soil has become widespread.
Generally, in the hydroponic cultivation apparatus, a hydroponic cultivation panel that holds plant seedlings is provided in a container such as a nutrient solution tank that supplies a nutrient solution.

  Conventionally, as a hydroponics panel, for example, a large number of openings are equally spaced and floated in a container filled with nutrient solution, and the opening of a perforated foamed polystyrene through urethane chips and rock wool The following Patent Document 1 describes a configuration in which a plant to be cultivated is held and fixed, and a configuration in which fired vermiculite is engaged with the opening of the perforated foamed polystyrene.

  In addition, for example, a support member having a notch formed at a width larger than the diameter of the seed at the opening of the planting panel floated on the nutrient solution, and the notch is provided so as to close the notch on the lower surface of the support member. And a non-woven fabric that can pass through the roots of young seedlings, and further has a structure in which a support member for hydroponics, in which the cross-section of the support member is bent into a V-shaped or U-shape, is assembled. This is disclosed in the following Patent Document 2.

  Also, for example, it is provided on a seat frame support base that can adjust the liquid level and height so that the grid-like seat frame can be covered with the liquid level of the nutrient solution tank, and the same as the seat frame on the grid-like seat frame The following Patent Document 3 discloses a configuration in which a woven fabric, a nonwoven fabric, or a film seed sheet in which concave portions for planting seeds of a plant to be cultivated are installed at a lattice pitch of

However, in the hydroponics panel configured to hold and fix the plant to be cultivated through urethane chips and rock wool at the opening of the perforated foam polystyrene described in Patent Document 1, urethane chips and rock wool are used. The seeds of the plant to be cultivated are sown and germinated in the used culture holder, and when the plant to be cultivated has grown to some extent, it is necessary to transplant the plant to be cultivated into the opening of the perforated polystyrene foam, making the work complicated There is a problem of doing.
Moreover, it is difficult to hold the sown seeds in a stable state in a cultivator holder using urethane or rock wool. One way to keep the seeds stable is to embed and fix the seeds in urethane or rock wool, but if the seeds are sown in the opposite direction to the buds, It is possible to change the orientation of the machine, making it difficult to grow.

  In addition, like the hydroponics panel described in Patent Document 1 and Patent Document 2, in the configuration in which the planted product holder is engaged or assembled with the opening of the perforated foamed polystyrene or the fixed planting panel floated on the nutrient solution, It is unstable when the perforated foamed polystyrene or planting panel floats on the surface of the liquid. Difficult to grow in

  Moreover, although a plant to be cultivated gradually becomes heavier as it grows, the growth is considerable in a perforated foamed polystyrene or a planting panel floated on the liquid surface used for hydroponics panels described in Patent Document 1 and Patent Document 2. It becomes difficult to hold the cultivation container with the plant to be cultivated with a certain degree of progress and the weight is stable, and there is bending and cracking around the hole holding polystyrene cultivation container and the cultivation container in the fixed planting panel. It may occur and adversely affect the cultivation of the plant to be cultivated thereafter. As a measure for avoiding such an adverse effect, it is conceivable to transplant a plant to be cultivated to some extent to another planting panel or the like, but this complicates the operation.

  Moreover, the individual cultivation holder | retainer is put in each opening part provided in many perforated foam polystyrenes and fixed planting panels floated on the nutrient solution like the hydroponics culture panel of patent document 1 and patent document 2. In each of the configurations that are engaged or assembled, the number of members increases, and the assembly work of the cultivation cage and the operation from seeding of the plant to be cultivated to harvesting, the seeding of the next seed after harvesting become complicated, The work efficiency becomes worse.

  Moreover, since the hydroponic cultivation panel of patent document 3 is a structure provided with the grid | lattice-like seat frame on the seat frame support stand which can adjust a liquid level and height, it describes in patent document 1 and patent document 2 Unlike the styrofoam and fixed-planting panels floated on the liquid surface that make up the hydroponics panel, it does not move with the flow of nutrient solution, but it forms recesses with the same lattice pitch as the lattice-like seat frame Providing a seed sheet of woven fabric, non-woven fabric, or film increases the number of components and makes the work from seeding of the plant to be cultivated to harvesting and sowing the next seed after harvesting complicated Inefficiency.

  Moreover, the hydroponics panel described in Patent Document 3 is provided with recesses for seeding seeds on the seed sheet at regular intervals, but the recesses are formed so as to be recessed from the flat part of the seed sheet. In such a shape, if a large number of seeds are sown on the seed sheet at a time, the seeds in contact with the flat part may bounce and come out of the seed sheet. Inevitably, the work efficiency of seed sowing becomes worse.

  The present invention has been made in view of the above problems, and while reducing the number of members as much as possible by simplifying the configuration, reducing the work burden of seeding of the plant to be cultivated, and the need to replant seedlings An object of the present invention is to provide a hydroponic cultivation tray that can be cultivated in a stable state and that can improve the working efficiency from the harvesting of a grown plant to be cultivated to the sowing of the next seed.

  In order to achieve the above object, a hydroponic cultivation tray according to the present invention comprises a nursery bed holding unit comprising a stainless steel wire mesh tray placed in a reverse direction in a container for circulating a hydroponic cultivation medium, and the nursery bed holding And a nursery part made of a wave-type sound absorbing sponge placed on the part.

  Moreover, in the hydroponics tray of the present invention, the seedbed part has a root diameter of a plant located in the valley part from the valley part of the wave-type sound absorbing sponge to the surface opposite to the valley part. It is preferable that a through hole having a size of 1 is formed.

  According to the hydroponics tray of the present invention, while simplifying the configuration and reducing the number of parts as much as possible, the work burden of seeding of the plant to be cultivated is reduced, there is no need to replant seedlings, and stable A hydroponics tray capable of being cultivated in a state and capable of improving the working efficiency from the harvesting of the grown plant to be cultivated to the sowing of the next seed is obtained.

It is a disassembled perspective view which shows roughly the whole structure of the tray for hydroponics concerning one Example of this invention. It is explanatory drawing which shows the structure of the seedbed part in the tray for hydroponics of FIG. 1, (a) is the figure seen from upper direction, (b) is an AA expanded partial end view of (a), (c) is from the downward direction FIG. It is explanatory drawing which shows the hydroponics process using the tray for hydroponics of FIG. 1, (a) is a fragmentary figure which shows the state at the time of seeding, (b) is a fragmentary figure which shows the state at the time of germination, (c) is a partial view showing a state in the middle of growth, (d) is a partial view showing a state at the time of harvesting, and (e) is a partial view showing a state when the seedbed is changed after harvesting.

Prior to the description of the embodiments, the effects of the present invention will be described.
The tray for hydroponic cultivation of the present invention is placed on the nursery bed holding unit composed of a stainless steel wire mesh tray placed in a reverse direction in a container for circulating the culture medium for hydroponic cultivation, and the nursery bed holding unit. And a nursery part made of a wave-type sound absorbing sponge.

  If the nursery bed holding part which consists of a stainless steel wire-mesh tray mounted in the reverse direction in the container which distribute | circulates the culture solution for hydroponics like the hydroponics tray of this invention, it is patent document 1 and patent It is not necessary to float on the nutrient solution like the foamed polystyrene and the fixed planting panel described in Document 2, and the seedbed part can be held by the seedbed holding part made of a wire mesh tray. For this reason, a plant to be cultivated can be cultivated in a stable state without being affected by the flow of nutrient solution or the growth state of the plant.

  Moreover, like the hydroponics tray of the present invention, if the nursery is composed of a wave-type sound absorbing sponge, without seeding the seeds individually at a predetermined position with a hole like the nursery bed of a conventional cultivation panel, The seeds sown by unevenness can be classified. In addition, unlike the seed sheet provided with the recesses described in Patent Document 3, the seedbed part has only a flat part and not a flat end part, so that the seed bounces out at the flat part and jumps out of the seedbed part. There is little possibility that it will end up. For this reason, seeding of a large number of seeds can be carried out with a single sowing operation while suppressing loss as much as possible, and the seed sowing operation burden can be greatly reduced.

  Moreover, in the structure which hold | maintained and fixed the plant to be cultivated through urethane chip or rock wool in the opening part of the perforated foam polystyrene as described in Patent Document 1, seeds were embedded in a conventional sponge or the like. When fixed, it inhibits the growth of the germinated seeds when the seed buds are planted upside down, but the nursery is composed of a wave-type sound absorbing sponge like the hydroponics tray of the present invention. For example, the mountain around the valley of the wave-shaped sound absorbing sponge becomes a wall and the seed can be fixed at a predetermined position, so that the seed can be held while being placed in the valley, and the part that becomes the seed bud is Even when planted upside down, the seeds can change direction, so they do not inhibit the growth of germinated seeds. In addition, the uneven shape of the wave-type sound absorbing sponge formed in the seedbed portion makes it easy to grow the plant placed in the valley portion upward.

  Moreover, like the hydroponic cultivation tray of the present invention, a nursery bed holding portion made of a stainless steel wire mesh tray placed in the opposite direction, and a nursery bed portion made of a wave-type sound absorbing sponge placed on the nursery bed holding portion When the plant to be cultivated is harvested, it is easy to lift the nursery bed holding part while holding the nursery bed part, remove it from the container and harvest it, and then replace the harvested nursery bed part with a new nursery bed part. In addition, the following cultivation environment can be created, and work for cultivation can be made efficient.

  For this reason, according to the tray for hydroponics of the present invention, while simplifying the configuration and reducing the number of members as much as possible, the burden of seeding of the plant to be cultivated is reduced, and there is no need to replant seedlings. Thus, it is possible to cultivate in a stable state, and it is possible to improve the work efficiency from the harvest of the grown plant to be cultivated to the sowing of the next seed.

  Moreover, in the hydroponics tray of the present invention, the size of the seedbed portion is about the diameter of the root of the plant located in the valley portion from the valley portion of the corrugated sound absorbing sponge to the surface opposite to the valley portion. If it comprises and has the through-hole which has, it will become easy to make the root of a plant for cultivation reach | attain a nutrient solution, will promote the growth of a plant for cultivation, and will become easy to increase a yield. Moreover, it becomes easy to stabilize the growth state of the cultivation target plant by straightening the growth direction of the root of the cultivation target plant.

FIG. 1 is an exploded perspective view schematically showing an overall configuration of a hydroponics tray according to an embodiment of the present invention. FIG. 2 is an explanatory view showing the configuration of the seedbed portion in the hydroponics tray of FIG. 1, (a) is a view from above, (b) is a sectional view taken along line AA of (a), and (c) is downward. FIG. FIG. 3 is an explanatory view showing a hydroponics process using the hydroponics tray of FIG. 1, (a) is a partial view showing a state at the time of seed sowing, and (b) shows a state at the time of germination. (C) is a partial view showing a state during the growth, (d) is a partial view showing a state at the time of harvesting, and (e) is a partial view showing a state when the seedbed is exchanged after harvesting. In addition, in FIG.3 (b)-FIG.3 (d), the seedbed holding | maintenance part has shown only the part which remove | deviated from the growth range of the root of the cultivation object plant for convenience.
The hydroponics tray 1 of this embodiment includes a seedbed holding unit 2 and a seedbed unit 3.

For example, the seedbed holding unit 2 is configured by a stainless steel wire mesh tray that can be placed in a reverse direction in a container 10 for circulating a culture medium for hydroponics such as a nutrient solution tank. The mesh of the wire mesh tray has a size and shape that does not hinder the growth of the root of the plant to be cultivated. In addition, the wire mesh tray has a strength that can be held without bending even when the nursery bed portion 3 having a size that allows the plant 20 to be harvested is placed with the tray turned upside down.
The nursery bed holding unit 2 may process and manufacture a wire mesh according to the size of the container 10.

For example, the seedbed part 3 is constituted by a wave-type sound absorbing sponge in which a large number of irregularities including a peak part 3d and a valley part 3a are formed on the surface of urethane foam.
Moreover, in the seedbed part 3, as shown in FIG. 2, the diameter of the root 20a of the plant 20 to be cultivated located in the valley part 3a from the valley part 3a of the corrugated sound absorbing sponge to the surface 3b opposite to the valley part 3a. A through hole 3c having a size of about a degree is formed.

The through-hole 3c of the seedbed part 3 is preferably created by using, for example, a hole puncher in which the same number of nails are driven in a flat plate in accordance with the position of the valley part 3a of the wave type sound absorbing sponge. Specifically, the through-hole 3c is opened with the nail by aligning the corrugated portion 3a of the wave-shaped sound absorbing sponge and the position of the nail of the punch, and placing the punch on the wave-shaped sound absorbing sponge and pressing it downward. . In this way, a large number of through holes 3c can be created simultaneously.
Moreover, in the example of FIGS. 1-3, although the seedbed part 3 was set as the structure which provided the through-hole 3c, the trough part 3a of the wave type sound-absorbing sponge which comprises the seedbed part 3 is on the opposite side to the trough part 3a. When the thickness up to the surface 3b is thin and the root 20a of the plant 20 is likely to reach the surface 3b on the side opposite to the valley 3a, a configuration in which the through hole 3c is not provided may be used.

  In addition, although illustration is abbreviate | omitted, the electric cylinder is connected to the seedbed holding | maintenance part 2 of the tray 1 for hydroponics of a present Example as a moving means to move to an up-down direction.

The cultivation process using the hydroponics tray 1 of the present embodiment configured as described above will be described with reference to FIG.
First, in the state where the seedbed part 3 is placed on the seedbed holding part 2 placed in the container 10 for circulating the culture medium for hydroponics such as a nutrient solution tank, the nutrient solution is poured and the seedbed part 3 Soak thoroughly in a wave-type sound absorbing sponge. Thereafter, seeds of the plant 20 to be cultivated are sowed. The sown seeds bounce off the bumps of the wave-type sound absorbing sponge, and each seed is dispersed in each valley 3a. Fig.3 (a) has shown the state by which the seed of the cultivation object plant 20 was disperse | distributed to each trough part 3a.

  After the seeds are sown, the upper surface of the seedbed 3 is covered with rock wool (not shown) or covered with toilet paper (not shown) so that the seeds are not dried. And the seed sown by the valley part 3a is germinated in the state where humidity was maintained. In addition, even if the direction of the seed buds when the seeds are sown on the seedbed part 3 is reversed, the seed buds are not fixed because the seeds are not fixed around the valleys 3a of the wave-type sound absorbing sponge. The direction can be changed upward after germination.

As the cultivation target plant 20 grows, the roots gradually grow downward while being guided by the through holes 3b. Thereby, the growth direction of the cultivation target plant 20 is stabilized. FIG. 3B shows a state where the roots of the cultivation target plant 20 have passed through the through holes 3b after the seeds of the cultivation target plant 20 germinate.
Furthermore, as shown in FIG.3 (c), when the cultivation object plant | plant 20 grows large, the weight of the seedbed part 3 will also become heavy. However, the nursery bed holding part 2 constituted by a wire mesh tray holds the surface 3b of the nursery bed part 3 opposite to the valley part 3a. For this reason, the nursery bed part 2 can grow the plant 20 to be cultivated in a stable state without being deformed, and it is not necessary to replant the seedling in another cultivation panel.

  When the cultivation target plant 20 grows to a size that can be harvested, an electric cylinder (not shown) is driven by a predetermined amount and, as shown in FIG. Lift part 2. The plant is harvested using a machine (not shown) or a human harvesting means.

After harvesting the plant 20 to be cultivated, the seedbed part 3 is removed from the seedbed holding part 2.
Next, the new seedbed part 3 is placed on the seedbed holding part 2, the electric cylinder is driven by a predetermined amount, the seedbed holding part 2 holding the seedbed part 3 is lowered and placed on the container 10. FIG. 3 (e) shows a procedure for placing the new seedbed part 3 on the seedbed holding part 2 and placing them on the container 10.
Then, hydroponics of the cultivation target plant 20 is repeated in the same procedure as described above.

  According to the hydroponic cultivation tray 1 of the present embodiment, since the nursery bed holding unit 2 composed of a stainless steel wire mesh tray placed in the reverse direction in the container 10 for circulating the hydroponic cultivation medium is provided, the patent It is not necessary to float on the nutrient solution like the foamed polystyrene and the fixed planting panel described in Document 1 and Patent Document 3, and the seedbed part 3 can be held by the seedbed holding part 2 made of a wire mesh tray. For this reason, the cultivation target plant 20 can be cultivated in a stable state without being affected by the flow of the nutrient solution or the growth state of the plant.

  In addition, according to the hydroponics tray 1 of the present embodiment, the seedbed 3 is made of a wave-type sound absorbing sponge, so that seeds are individually planted at a predetermined position with a hole like the seedbed of a conventional cultivation panel. The seeds sown by the unevenness can be separated without any problems. In addition, unlike the seed sheet provided with the recesses described in Patent Document 3, the seedbed part 3 is provided with only irregularities without flat ends, so that the seed bounces out at the flat part and jumps out of the seedbed part. There is little fear that it will be. For this reason, seeding of a large number of seeds can be carried out with a single sowing operation while suppressing loss as much as possible, and the seed sowing operation burden can be greatly reduced.

  Moreover, in the structure which hold | maintained and fixed the plant to be cultivated through urethane chip or rock wool in the opening part of the perforated foam polystyrene as described in Patent Document 1, seeds were embedded in a conventional sponge or the like. When fixed, when the seed bud part is planted upside down, the growth of the germinated seed is inhibited, but according to the hydroponics tray 1 of this example, the seedbed part is made of a wave-type sound absorbing sponge. 3 so that the peak 3d around the trough 3a of the wave-shaped sound absorbing sponge becomes a wall and the seed can be fixed at a predetermined position, so that the seed can be held in the state where it is placed on the trough 3a, Even when the seed buds are planted upside down, the seeds can change direction, and thus do not inhibit the growth of the germinated seeds. Moreover, the uneven shape of the wave-type sound absorbing sponge formed on the seedbed part 3 makes it easy to grow the plant 20 placed on the valley part 3a upward.

  Moreover, according to the hydroponics tray 1 of the present invention, the nursery bed holding part 2 made of a stainless steel wire tray placed in the opposite direction and the wave-type sound absorbing sponge placed on the nursery bed holding part 2 Therefore, when the plant 20 to be cultivated is harvested, the nursery bed holding unit 2 is lifted up with the nursery bed 3 held and taken out from the container 10 and harvested. Then, the harvested nursery bed 3 is renewed. By simply exchanging with the seedbed part 3, the next cultivation environment can be easily created, and the work for cultivation can be made efficient.

  For this reason, according to the hydroponics tray 1 of the present embodiment, while simplifying the configuration and reducing the number of members as much as possible, it is possible to reduce the burden of planting seeds of the plant to be cultivated and to replant seedlings. Therefore, it is possible to cultivate in a stable state, and it is possible to improve the work efficiency from harvesting the grown plant to be cultivated to sowing the next species.

  Moreover, according to the hydroponics tray 1 of the present embodiment, the seedbed 3 is placed on the valley 3a from the valley 3a to the surface 3b opposite to the valley 3a of the corrugated sound absorbing sponge. Since the through-hole 3c having a size about the diameter of the root 20a is formed, the root of the cultivation target plant 20 can easily reach the nutrient solution, promote the growth of the cultivation target plant 20, and increase the yield. It becomes easy. Moreover, it becomes easy to stabilize the growth state of the cultivation target plant 20 by making the growth direction of the root of the cultivation target plant 20 straight.

  The tray for hydroponics of this invention is useful for the hydroponic cultivation apparatus grown using a nutrient solution without using soil.
