As a planting board, the specific gravity is small so that it floats on the water,
Moreover, inexpensive and easy-to-handle foamed styrene boards are generally used.

[Problems to be solved by the present invention]

I) When seeds of a crop are planted on a fixed planting board, a germination room is generally used to germinate the seeds as quickly as possible, and to germinate and grow the seeds all at a uniform quality and growth rate. After that, it is relocated to the water tank together with the planting boards. The germination chamber is adjusted to a condition suitable for germination, such as humidity and temperature. Nevertheless, it is desirable that the fixed planting board on which the seeds have been sown are brought into the germination chamber in a state of being sprayed with water once and then wetted, and have a configuration capable of sufficiently supplying the necessary water during the subsequent germination period. However, no structure that satisfies this point has been observed in conventional planting boards. II) In either the hydroponic method of circulating the nutrient solution or the hydroponics method of storing the nutrient solution and using it in the water state without replenishment, long sunlight cultivation in the nutrient solution in the aquarium results in long cultivation. During the period, algae develop in the aquarium, and these algae become foci of bacteria and pathogenic fungi, cause lack of oxygen and nutrients in nutrient solution that inhibits the growth of crops, and produce large amounts of harmful small flies. Or cause it. Not only that, sunlight that has entered the nutrient solution raises the temperature of the nutrient solution, raises the root temperature of the crop, impairs growth and causes root rot. Therefore, it is preferable that the planting plate is a structure that blocks the incidence of sunlight, particularly as an airtight and heat-insulating shield that covers the aquarium lid or the nutrient solution surface. Is not heard. III) The seedlings are planted in a germination room as much as possible. The stacking state is such that seeds that germinate over about three days to one week have an air layer and a space that has a breathable air without fear of getting moldy or stuffy, and a size that does not hinder the growth of germinated seedlings. It is desired that a gap is secured. It is also desirable that the gap is minimized and the stacking efficiency is high. However, when the planting board is stored in a warehouse or the like when not in use, it is also desired that the planting board has a structure that can be stored as compactly as possible. IV) Therefore, the object of the present invention is to presume a cultivation method in which seeds are germinated and seedlings are grown using a germination chamber as described above, and water is sprayed on a fixed planting plate about once before being carried into the germination chamber. An object of the present invention is to provide an improved planting board having a structure in which a necessary amount of moisture is sufficiently secured during the germination period when wetted. The next object of the present invention is that the planting board taken out of the germination chamber is
When transferred to the water tank containing the nutrient solution, the seam between the planting boards adjacent in the longitudinal direction of the water tank is shielded so that sunlight does not enter the nutrient solution, and connected in an airtight state, Another object of the present invention is to provide a planting board improved in structure that can be easily connected to such an extent that the connection is not inadvertently detached. A further object of the present invention is to provide a space between the planting boards stacked vertically in a germination chamber or the like, which secures an air layer having sufficient air permeability necessary for germination of seeds and does not hinder the elongation of germinated seedlings. It is an object of the present invention to provide an improved planting board having a structure that is secured and can be stored in a compact stacking state without being as bulky as possible when the planting board is stored in a warehouse or the like when not in use.

I do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments and examples of the present invention shown in the drawings will be described. The planting board 1 shown in FIG. 1 and FIG. 2 is obtained by planting a desired crop or its seed into a plurality of planting holes 2 penetrating in the thickness direction of the planting solution, for example, as shown in FIG. Float on the liquid surface,
Alternatively, it is used as a so-called culture medium for growing and cultivating crops in such a manner that the nutrient solution 5 is absorbed by the roots of the crops by being placed on the support portions 6 provided on both sides of the opening of the water tank 4 as shown in FIG. 3B. . The fixed planting board 1 shown in FIG. 1 is made of a styrene foam resin plate having a small specific gravity and manufactured inexpensively and lightly, but is not limited thereto. The material of the planting board 1 can be manufactured and implemented by a non-foamed synthetic resin board, a wood board, or, in an extreme case, a metal board. As shown in FIG. 1, the thickness of a planting board 1 made of a styrofoam resin board is 30 mm, and the vertical and horizontal dimensions are 5
Usually, about 00 × 700 mm is used. In the embodiment of FIG. 1, the planting holes 2 are arranged in five columns in the vertical direction and three rows in the horizontal direction, and are formed in a vertically long slit shape (having a width of about 26 mm and a length of about 130 mm). However, the size and material of the planting plate 1 and the arrangement, shape, size, number and the like of the planting holes 2 are not limited to those in the embodiment of FIG. Depending on the scale of the cultivation facility, the type of crop to be cultivated, the seeds of the crop to be planted, and the seedlings, it is appropriately designed and manufactured so as to be convenient for use. For example, the planting hole 2 may be a round hole, a square hole, an elliptical hole, an oval hole, a triangular hole, a polygonal hole, or the like. Since the fixed planting hole 2 of the embodiment shown in FIG. 1 has a long slit shape,
As a means for stabilizing the mounting state of the seeding holding sheet described later, a middle crosspiece 8 is formed at a substantially central portion in the longitudinal direction of the slit. The middle crosspiece 8 is used to transfer the fixed planting board 1 to the nutrient solution 5.
When floating on the liquid surface, the holding sheet and the seeds supported by it must be held slightly above the nutrient liquid surface, that is, formed horizontally as a bar having a height of about 8 mm from the bottom of the plate. (FIGS. 4 and 5). Similarly, at both end portions of the fixed planting hole 2, sheet receiving portions 9 for receiving both end portions of the holding sheet are formed in a V-shape, and the bottom portion thereof is formed at the same height as the middle rail 8 (FIG. 4, FIG. 5). Therefore, as shown in FIG. 4, the crop seed 11 can be easily put into a stable state simply by folding the holding sheet 10 having the same length as the slit into two and inserting it in the longitudinal direction of the planting hole 2. However,
The means for inoculating seeds or seedlings into the fixed planting holes 2 is not limited to the holding sheet 10, but a urethane sponge sheet or small block, a piece of paper, a cotton cloth, or the like can be appropriately used. On the upper surface of the planting board 1 shown in FIG.
A low bank 7 forming a water pool W is formed in a rib shape and a closed loop shape so as to surround each of the planting holes 2. The height of the embankment 7 is about 2 mm as an example, and if a part of the water sprinkled when the seeds are planted on the fixed planting plate 1 is slightly left in the water pool W in a state like a drop, it is sufficient. . As is clear from FIG. 4, the bank 7 is formed along the entire edge of the fixed planting hole 2 along the periphery thereof. The meaning is to prevent the water secured by the dam 7 from flowing unnecessarily to the fixed planting holes 2 and to protect them when they are stacked and carried into the germination chamber as shown in FIG. It is expected that the water will evaporate appropriately, such as when the cover is covered, and the humid atmosphere will be maintained at least for the germination period. Therefore, the height of the bank 7, the size and shape of the water pool W surrounded by the bank,
The range and the like are also designed and manufactured based on the above considerations. For example, in the case of FIG. 1, the dam 7 has substantially the same shape on both sides of the planting hole 2.
Although two rectangular enclosures (water pool portions W) are formed in the same size and arranged in parallel, this is only an example. If the planting hole 2 is a round hole or a square hole having a relatively small diameter, the dam 7 may be formed so as to largely surround some of the planting holes. Further, as shown in FIG. 8, a concave surface 7 is formed by recessing a certain area of the upper surface of the planting board 1 as a water pool.
Alternatively, the present invention can be implemented with a configuration including a plurality of grooves (including a group of parallel or intersecting grooves) formed in an appropriate range as shown in FIG. In short, the pool W
It suffices to provide the necessary size and range in any part of the upper surface of the planting board 1 for the purpose of use. FIGS. 8 and 9 also show different examples of the cross-sectional shape of the planting hole 2 and different examples of the seed holding sheet 10 (holding material).
In the fixed planting board 1, at one end (right end in FIGS. 1 and 6) orthogonal to the longitudinal direction of the water tank, a connection step portion 13 for lap splicing is formed in a stepwise manner that divides the board thickness into approximately two. Also at the other end (the left end in FIGS. 1 and 6), a step portion 15 for lap splicing is formed in a stepwise manner that also bisects the plate thickness, and these are configured so that they can be spliced up and down alternately. The overlap margin of the connection step portions 13 and 15 is set to about 16 mm. Therefore, by connecting the connecting steps 13 and 15 vertically, the seam between the planting boards adjacent in the longitudinal direction of the water tank completely blocks sunlight from entering the nutrient solution in the water tank. And a seam structure having both heat insulation and airtightness equivalent to one continuous plate. Therefore, generation of algae in the water tank due to the incidence of sunlight and an increase in the temperature of the nutrient solution in the water tank are prevented. In addition, in the cold season, a heat insulating effect of preventing heat radiation from the surface of the nutrient solution is exerted, and a favorable environment for crop cultivation is provided. As a connecting means for properly and reliably maintaining the spliced (connected) state of the connection step portions 13 and 15, the lower surface side of the connection step portion 13 at one end (the right end in FIGS. 1 and 6) is provided. At the center in the width direction, a dovetail-shaped projection 14 having a dovetail shape as viewed in plan is formed as a downward projection to the limit of the plate thickness. The connection step 15 at the other end (the left end in FIGS. 1 and 6) has a dovetail-shaped recess having a shape and size in which the dovetail 14 fits downward at the center in the width direction. 16 are formed in a notch shape in the vertical direction. Therefore, when the planting board 1 is floated on the liquid surface of the nutrient solution 5 in the water tank 4 as shown in FIG. 3A, or when the planting board 1 is supported by the support portion 6 of the water tank 4 as shown in FIG. At the same time that the connecting step portions 13 and 15 of the two fixed planting boards 1 and 1 adjacent to each other in the longitudinal direction of the water tank 4 are staggered up and down alternately, one dovetail 14 is connected to the other dovetail recess 16 at the same time. Into the water tank 4
A plurality of fixed planting boards arranged in a longitudinal direction (a direction perpendicular to the paper surface of FIG. 3) can be connected in series with one touch by simple processing. As a result, the spliced state of the connecting steps 13 and 15 is mechanically strongly maintained by the strong connection between the dovetail 14 and the dovetail-shaped recess 16, so that sunlight enters the nutrient solution in the aquarium. This is blocked for a long time and is good, and the heat insulation and airtightness of the nutrient solution are well maintained. Further, a stable seam can be ensured so that the fixed planting boards do not shift laterally. As described above, the connecting step portions 13 and 15 achieve their purpose by being staggered up and down alternately, and thus are not limited to the step-like form. The form of a tapered surface inclined in a tapered shape, the form of fitting of a tenon and a tenon groove, and the like can be similarly implemented. As for the connecting means, as illustrated in FIG. 10, an upward concave surface 20 is formed on the lower surface of one connecting step 13, and an upward convex 21 is formed on the upper surface of the other connecting step 15. As illustrated in FIG. 11, a configuration in which an upward projection 22 is provided on the upper surface of one connection step 15 and a hole 23 in which the projection 22 fits closely is provided in the other connection step 13. And so on.
In an extreme embodiment, the connection is performed using a connection tool such as a separately prepared scallop, and the same operation and effect can be obtained. Next, support legs 12 are provided on the lower surface (or upper surface) of the planting board 1 in an arrangement and shape matching the arrangement and shape of the planting holes 2. This support leg 12
At the time of carrying the fixed planting board 1 on which the seeds or the seedlings of the crop are planted into the germination chamber, or transporting the planting board 1 from the germination chamber to a place with an aquarium and arranging the same, the seedlings may be damaged even if they are stacked as shown in FIG. This is for forming a gap of a small extent, and is protruded at a height of about 15 mm from the bottom surface of the plate. Providing the support legs 12 in an arrangement and shape that matches the arrangement and shape of the planted holes 2 means that the length and width of the support legs 12 are equal to those of the planted holes 2 as shown in FIG. This means that they are substantially the same shape, the same size, and are provided side by side at a position adjacent to the planting hole 2. As a result, especially when the planting board 1 is used up and stored in a warehouse or the like, the thing shown in FIG.
Can be compactly stacked in a state of being closely adhered to the planting holes 2, yet the ends of the upper and lower planting boards 1 are vertically aligned substantially in a straight line, and can be stored in a small, tidy state. .

The planting plate for hydroponics according to the present invention, when water is sprayed on the planting plate about once just before being carried into the germination room, the germination period of the crop is caused by water droplets remaining in the water pool. The necessary moisture inside is sufficiently secured. Also, when the planting board taken out of the germination chamber is transferred to the water tank containing the nutrient solution, the seam between the planting boards adjacent in the longitudinal direction of the water tank is completely so that sunlight does not enter the nutrient solution. In addition to being able to be connected in an airtight and adiabatic state, the connection can be easily performed so strongly that the connection state is not inadvertently detached. Therefore, an environment suitable for growing and cultivating crops can be maintained. . In addition, an air layer having sufficient air permeability necessary for germination of seeds is secured between the planting boards stacked vertically in a germination chamber or the like, and a gap that does not hinder elongation of germinated seedlings is secured. On the other hand, when the planting board is stored in a warehouse or the like when not in use, it can be stored in a compact stacking state without being as bulky as possible, and all of the germination, cultivation, and cultivation of the crop can be performed well.

Similarly, at both end portions of the fixed planting hole 2, sheet receiving portions 9 for receiving both end portions of the holding sheet are formed in a V-shape, and the bottom portion thereof is formed at the same height as the middle rail 8 (FIG. 4, FIG. 5). Therefore, as shown in FIG. 4, the crop seed 11 can be easily put into a stable state simply by folding the holding sheet 10 having the same length as the slit into two and inserting it in the longitudinal direction of the planting hole 2. However, seeds or seedlings must be planted
The means for planting is not limited to the holding sheet 10 described above.
A sheet or small block of urethane sponge, a piece of paper, a cotton cloth, or the like can be properly used.

On the upper surface of the planting board 1 shown in FIG . 1, a low dam 7 forming a water pool W is formed in a rib-like and closed loop shape so as to surround each of the planting holes 2 described above. The height of the embankment 7 is about 2 mm as an example, and if a part of the water sprinkled when the seeds are planted on the fixed planting plate 1 is slightly left in the water pool W in a state like a drop, it is sufficient. . As is clear from FIG.
Is formed on the entire periphery along the edge of the. The meaning is to prevent the water secured by the dam 7 from flowing unnecessarily to the fixed planting holes 2 and to protect them when they are stacked and carried into the germination chamber as shown in FIG. It is expected that the water will evaporate appropriately, such as when the cover is covered, and the humid atmosphere will be maintained at least for the germination period. Therefore, the height of the embankment 7,
The width, shape, range, and the like of the water pool W surrounded by the dam are also designed and manufactured based on the above-mentioned considerations. For example, in the case of FIG. 1, the dam 7 has two rectangular enclosures (water pools W) formed on both sides of the fixed planting hole 2 in substantially the same shape and the same size and arranged in parallel, but this is only an example. If the planting hole 2 is a round hole or a square hole having a relatively small diameter, the dam 7 may be formed so as to largely surround some of the planting holes. As the water pool, a concave surface 70 formed by recessing a certain area of the upper surface of the planting board 1 as shown in FIG. 8 or a plurality of grooves (parallel or intersecting) formed in an appropriate area as shown in FIG. (Including a group of grooves to be formed) to recesses 71 and the like. In short, it is sufficient for the water reservoir W to be provided in any area on the upper surface of the planting board 1 in a necessary width and range for its use. FIGS. 8 and 9 also show examples of different cross-sectional shapes of the planting hole 2 and the seed holding sheet 10.
Different examples of (holding material) are shown.

At the one end (right end in FIGS. 1 and 6) orthogonal to the longitudinal direction of the aquarium, a connecting step portion 13 for lap splicing is formed in a stepwise manner that halves the plate thickness. Also formed at the other end (the left end in FIGS. 1 and 6) is a stair-like splicing step 15 which also bisects the plate thickness, and these are configured to be stitched alternately up and down. ing. The overlap margin of the connection step portions 13 and 15 is set to about 16 mm. Therefore, by connecting the connecting steps 13 and 15 vertically, the seam between the planting boards adjacent in the longitudinal direction of the water tank completely blocks sunlight from entering the nutrient solution in the water tank. Connection state, and 1
The seam structure has the same heat insulation and airtightness as if the plates are continuous. Therefore, generation of algae in the water tank due to the incidence of sunlight and an increase in the temperature of the nutrient solution in the water tank are prevented. In addition, in the cold season, a heat insulating effect of preventing heat radiation from the surface of the nutrient solution is exerted, and a favorable environment for crop cultivation is provided.

As a connecting means for maintaining the spliced (connected) state of the connecting step portions 13 and 15 satisfactorily and reliably, the connecting step 13 is provided at one end (the right end in FIGS. 1 and 6) on the lower surface side of the connecting step 13. In the center of the width direction, a dovetail-shaped dovetail portion 14 as viewed in plan is formed as a downwardly protruding portion to the thickness limit. The connection step 15 at the other end (the left end in FIGS. 1 and 6) has a dovetail-shaped recess having a shape and size in which the dovetail 14 fits downward at the center in the width direction. 16 are formed in a notch shape in the vertical direction.

[0018] Therefore, when the floated on the liquid surface of the nutrient solution 5 in water tank 4 as the planting plate 1 e.g. FIG. 3A, and FIG 3B
When the planting board 1 is supported by the support portion 6 of the water tank 4 as described above, two planting boards 1, 1 adjacent in the longitudinal direction of the water tank 4 are used.
The connecting step portions 13 and 15 are staggered up and down alternately, and at the same time, one dovetail 14 is fitted into the other dovetail-shaped recess 16 in the up-down direction, so that the longitudinal direction ( A plurality of fixed planting boards arranged in a direction (perpendicular to the plane of the paper of FIG. 3) can be connected in series with one touch by simple processing. As a result, the dovetail 14 and the dovetail recess 16 are formed.
The connection between the connecting steps 13 and 15 is mechanically strongly retained by the strong coupling action with, so that the sunlight can be prevented from entering the nutrient solution in the aquarium for a long time and satisfactorily,
In addition, the heat insulation and airtightness of the nutrient solution surface are favorably maintained. Further, a stable seam can be ensured so that the fixed planting boards do not shift laterally.

As described above, the connecting step portions 13 and 15 achieve their purpose by being alternately overlapped vertically, and thus are not limited to the step-like form. The form of a tapered surface inclined in a tapered shape, the form of fitting of a tenon and a tenon groove, and the like can be similarly implemented. As for the connecting means, as illustrated in FIG. 10, an upward concave surface 20 is formed on the lower surface of one connecting step 13, and an upward convex 21 is formed on the upper surface of the other connecting step 15. As illustrated in the configuration or FIG.
Of the other connecting step 13
Can be implemented with a configuration in which a hole 23 into which the above-mentioned protrusion 22 fits closely is provided. As an extreme example,
The same operation and effect can be obtained by performing connection using a connection tool such as a scallop prepared separately.

Next, the lower surface of the planting plate 1 (or soluble in an upper surface)
Are provided with support legs 12 in an arrangement and shape that match the arrangement and shape of the planting holes 2. This support leg 12
In the work of carrying the fixed planting board 1 on which the seeds or the seedlings of the crop are planted into the germination room, or transporting the planting plant 1 from the germination room to the location of the water tank and arranging the seedlings, as shown in FIG. Is formed so as not to be damaged, and protrudes from the bottom of the plate at a height of about 15 mm. Planting hole 2
Providing the support legs 12 in an arrangement and shape that matches the arrangement and shape of the support legs 12 means, for example, that the length and width of the support legs 12 are substantially the same as those of the fixed planting holes 2, as shown by the dotted lines in FIG.
It means that they are the same size and are provided side by side at a position adjacent to the planting hole 2. As a result, especially when the planting board 1 is used and stored in a warehouse or the like, when the thing in FIG. 1 is horizontally inverted by 180 ° and stacked, the support leg 12 is fitted into the planting hole 2 and is in close contact with the planting hole 2. Can be stacked in a compact manner, yet the top and bottom fixed planting boards 1
The edges of the are vertically aligned in a substantially straight line, and can be stored in a small, tidy state.
