  Related to hydroponics technology.

Compared to outdoor cultivation and house cultivation using soil, hydroponic cultivation of vegetables, which is not affected by the natural environment, has attracted attention. However, it is hard to say that it is spreading due to high cultivation costs.
Various devices have been proposed for cultivation devices and cultivation processes. One of them is the adjustment between stocks that requires labor. Plants grow gradually until they are harvested from the seed, and require an area that matches their size. A technique has been proposed that expands between adjacent strains according to this growth.
In JP-A-8-98633 (Patent Document 1), a plurality of plant support bodies 2 in which holes 4 for supporting plants are arranged are arranged in parallel in the width direction and are made of a foldable sheet material. In the plant cultivation panel in which the entire width is freely expandable / contractable by being connected to each other by the connecting sheet 3, one end is at one side end at the engaging portion 10 provided at least at one end in the longitudinal direction of each plant support 2. A slide plate 12 made of a bendable material fixed to the plant support side located is slidably engaged, and a free end 12a of the slide plate 12 is placed on the side of the plant support 2 located at the other end. It is characterized in that a storage portion 15 is provided to allow the user to freely enter and exit.
In Japanese Patent Laid-Open No. 7-99853 (Patent Document 2), a plurality of feed lines 16A and return lines 16B of the first to third stages are arranged in parallel, and the lane shifter 17 and the panel server 18 distribute the panels. And collect. Multiple lines are sent at a speed that is a fraction of the number of one line. Thereby, sufficient cultivation time comes to be secured for the cultivation panel which passes through a plurality of parallel parts.
Japanese Utility Model Laid-Open No. 5-74252 (Patent Document 3) discloses a sheet in which strip panels 12 as a plurality of plant supports formed with holes 11 for supporting plants are arranged in the width direction and the strip panels 12 are foldable. The panel frames 14A and 14B having the engaging portions 17A and 17B are attached to both ends in the longitudinal direction of the strip panel 12, and the slide bars 15A and 15B are passed through the engaging portions 17A and 17B.

In the cultivation method which adjusts between strains according to the growth of a cultivated plant using the laminated cultivation panel as described in 1., the cultivation method characterized by including the following cultivation process.
1st process: The process of planting sowing or a seedling in the hole for plant fixation of a cultivation panel, and cultivating,
Second step: When adjusting between strains once or several times, increasing the number of cultivation panels planted with the plant cultivated in the previous step, placing it on the cultivation bed, and cultivating,
Third step: In the final inter-strain adjustment, cultivation panel and 6. Combining the closing panels described in
Fourth step: A step of cultivating and harvesting until the harvest time.

1. This invention implement | achieved the hydroponics panel which can perform between strain adjustments without using a complicated structure and apparatus in a hydroponic cultivation, without accompanying a replanting.
Each cultivation panel used in the present invention has a simple structure because it is only a panel in which a hole is made in a single panel of foamed resin or plastic is molded.
It is a cultivation panel that can adjust between plants according to the growth of the plant, and has a hole for fixing the plant and a hole for passing the plant body. The plant body being planted can grow through the plant body passage hole provided in the upper cultivation panel, or the upper cultivation panel can be removed.
When plants (vegetables) are small, these cultivation panels can be stacked and cultivated, separated according to their growth, and sequentially spread on a cultivation bed for use. By removing the cultivation panel from the cultivation panel laminated in this manner, the plant is fixed and separated in the plant fixing hole of the removed cultivation panel, and the plant fixing hole is similarly formed in the lower cultivation panel. Since the plant planted in can pass through the upper passage hole, it is still fixed to the lower cultivation panel. By transferring the separated upper cultivation panel to the cultivation bed, the amount of the strain remaining on the upper and lower cultivation panels becomes a spread between the strains, so that adjustment between the strains can be performed.
In each cultivation panel to be combined, the arrangement of the seedlings to be planted first will be planned along the plant arrangement in the harvest period. Moreover, the hole for plant fixation provided in the cultivation panel laminated | stacked up and down and the hole for plant body passage can be previously set supposing the harvest season.
Plant fixing holes to be provided in individual cultivation panels are provided so as to be in the planting state during the harvesting period, arranged so as not to overlap with the plant fixing holes in the harvesting period, and further, plant fixing of other cultivation panels The cultivation panel laminated | stacked up and down is arrange | positioned so that use holes may not overlap.
In the upper cultivation panel that is stacked and combined, there will be a hole for passing the plant body through which the plant planted in the lower cultivation panel can pass, so that between the strains in order according to the number of adjustments between the strains Inter-share adjustments can be repeated until adjustments are made between the final shares.
If the number of cultivated panels is set to an index number of 2, it will be divided into half the number of layers for each inter-strain adjustment, and the cultivation area can be doubled.
Transpiration of the cultivation solution and the like can be prevented by closing the hole for passing the plant with the closing panel when the final cultivation interval is reached.
2. By using this laminated cultivation panel, it is not necessary to replant each plant body, and adjustment between the strains can be performed by separating and moving the upper and lower cultivation panels.
3. Since the area used for cultivation increases according to the inter-strain adjustment work, it is only necessary to utilize the cultivation area required according to the growth stage of the plant, and the cultivation cost can be reduced.

The present invention relates to a hydroponics panel for use in hydroponics such as a solution method and a spray method. Plants grow gradually from sowing to harvesting, not limited to hydroponics. Adjustments are made to increase the spacing between adjacent plants according to the growth. This is called inter-share adjustment.
From sowing to shipping, the process of “seeding → raising seedlings → fixed planting → planting (thinning, adjustment between strains) → harvesting → inspection / packaging → shipping” is performed. Generally, a panel according to each cultivation process, such as a seeding sheet, a planting panel, and a panel to be planted and grown, is necessary, and a planting operation is required each time. In cultivated plants, it is mainly used for cultivation of lettuce, spinach, Japanese mustard spinach, mizuna, herbs and the like.

The present invention is a hydroponics panel that can be used consistently from sowing to harvesting, and is a laminated cultivation panel that is combined and laminated.
In the laminated cultivation panel of the present invention, plants are fixed to individual cultivation panels in a position different from other cultivation panels in consideration of the final inter-strain interval, which is the harvest period interval ("planting", "fixed planting", " Holes (called “planting” etc.) are formed. And in each cultivation panel, the hole which a plant body passes is formed in places other than the hole for plant fixation (the part corresponding to the hole for plant fixation of the other cultivation panel laminated | stacked). . In addition, the cultivation panel used normally is planted in a grid | lattice form etc. so that it may become a uniform cultivation density. The present invention is also premised on rational cultivation. The plant body passage hole provided in the cultivation panel is a hole through which leaves of plants remaining on the panel below the inter-strain adjustment panel to be removed pass.
As the material of the cultivation panel, a commonly used material such as a foamed resin plate or a plastic molded plate can be used. It can be reinforced with frame material or beam material as needed. A handle can be provided at the edge of the cultivation panel to improve operability. When providing this handle, in the cultivation panel for lamination | stacking, the position of a handle can be changed and it can devise, such as making it easy to handle.

Germination can be carried out by germination by filling a hole for plant fixation of each laminated cultivation panel with a sponge or a sowing pot and sowing the seed. Alternatively, after sowing and raising seedlings separately, the seedlings can be transplanted into the plant fixing holes of the laminated cultivation panel and planted in each cultivation panel.
After planting, according to the growth of the plant, remove the laminated cultivation panel and spread it on the cultivation bed to adjust the strain. For example, by separating half of the number of stacked sheets as a set and removing the cultivation panel and placing it on the cultivation bed, it is possible to widen the strain. Then, according to the inter-strain adjustment, half the number is removed, and the cultivation is continued on the cultivation bed. Moreover, the laminated cultivation panel which piled up the three cultivation panels can be expand | deployed on a cultivation bed by separating three pieces.
And by combining with a closing panel at the time of the last adjustment between strains, the hole for plant passage is closed and transpiration of a cultivation solution, etc. can be prevented. After the final inter-strain adjustment, the opening area by the plant passage hole is the largest, so a closing panel is provided to minimize the influence of the opening. In addition, this closing panel can also manufacture and use the closing panel for intermediate | middle according to the laminated cultivation panel at the time of adjustment between intermediate strains.

By removing the cultivation panel according to plant growth and spreading it on the cultivation bed, the present invention can adjust the strain without transplanting individual plants. It is an invention that makes it possible to adjust between stocks with a simple device that "does a hole" that does not require complicated equipment such as a stock-to-stock adjustment device or folding for folding.
The laminated cultivation panel of the present invention is suitable for hydroponics using a cultivation bed. Hydroponics is suitable for solution cultivation and spray (mist) cultivation. Leafy vegetables such as lettuce are suitable for growing plants. Leafy vegetables are fast growing and can be cultivated in a cycle of 1 to 2 months, so the effect of saving labor such as replanting is great.
In plant factories and the like that are continuously cultivated by moving in one direction on one lane from sowing to harvesting, inter-strain adjustment can be automatically performed using a laminated hydroponics panel. For example, it can be carried out by providing a lift-up device at the inter-stock adjustment point, lifting the panel to be divided, and providing a gap back. In this case, if the position of the handle is specified by the panel, lift-up is easy.

<Embodiment 1>
Embodiment 1 of the present invention will be described.
The laminated cultivation panel 100 and the laminated cultivation panel ABCD are shown in FIG.
In the laminated cultivation panel 100, four cultivation panels ABCD are laminated.
This cultivation panel is based on a panel having a size capable of providing 24 holes for planting (plant fixing holes). Four individual cultivation panels are provided with six plant fixing holes 2 at positions different from those of other cultivation panels. And the big plant passage hole 3 is provided in other 18 places. Six plant fixing holes 2 provided in the cultivation panel are arranged at the final inter-strain adjustment interval. In the laminated cultivation panel 100 in which the four sheets are laminated, the arrangement of the holes provided in the uppermost cultivation panel is shown, but there are holes for fixing plants in all 24 holes in a plan view. Will do.
Needless to say, the number of holes is not limited to 24. Depending on the type of cultivated plant and the size of the harvest season that is set, the stock will vary, so a cultivation panel that matches that will be designed.

An example of the cultivation panel is shown in FIG.
FIG. 2 shows a cultivation panel C as an example. Plant fixing holes 2 are provided at intersections between the first row, the third row, the second column, the fourth column, and the sixth column. Plant intersection holes 3 which are large holes are provided at the intersections of other rows and columns. As shown in the cross-sectional view, a seedling 5 of a plant for cultivation is planted in the plant fixing hole 2. An enlarged view of the plant fixing hole 2 is shown in FIG. In the plant fixing hole 2, a seeding sheet 4 in which a seeding depression is formed is inserted. This seeding sheet can be seeded and germinated to grow into seedlings. A seedling pot can also be used as the seeding sheet. The size of the plant fixing hole is set to a size that can support the root of the plant until harvest. The state of the cultivation panel of the seedling raising state using a sowing sheet and a sowing pot is shown in FIG. In the sowing sheet, the sheet is filled in the hole for plant fixation, seeded and budding. In the case of a cultivation pot, the edge of the pot is caught on the edge of the hole of the cultivation panel.
This sowing and seedling growth can be carried out by using a dedicated seedling raising facility or by directly sowing the laminated cultivation panel 100. In the case of using the seedlings that have been raised, seedlings are planted on the laminated cultivation panel 100.
This cultivation panel is about 900 mm × 700 mm in size and is based on a 140 mm grid.

The closing panel is shown in FIG.
4 of the closing panels ABCD. Each closing panel corresponds to the cultivation panel ABCD. In the closing panel, holes equivalent to the plant passage holes 3 are formed in the portions corresponding to the six plant fixing holes provided in the corresponding cultivation panel, and the other portions are blinded. It has become.
The four closing panels are prepared separately from the stacked cultivation panel 100, and are used in combination with the corresponding cultivation panels at the time of the final inter-strain adjustment (the second inter-strain adjustment in this embodiment).
Since each planting panel is provided with 18 plant passage holes 3, if it is cultivated as it is, the solution or spray will evaporate from the opening, so it is closed with a closing panel to prevent this. And
In addition, since the 12 plant passage openings can be made even in the first inter-strain adjustment, as a countermeasure against this, a closing panel for closing these 12 openings can be provided.

Fig. 4 shows an image of plant growth taking leafy vegetables as an example.
The image of the growth of leafy vegetables suitable for hydroponic cultivation is that the diameter of the seedlings is about 40 mm when starting the cultivation start date when the seedlings that have been sown and seeded are planted, and this is 140 mm in 10 days of cultivation. It becomes 200 mm in 20 days of cultivation and about 240 mm in the harvest period of 30 days of cultivation. This is an example, and may vary depending on environmental management such as the type and temperature of vegetables.
Inter-strain adjustments are made according to this growth. In this embodiment, inter-strain adjustment on the 10th day and 20th day of cultivation is performed. In the first laminated panel, plant fixing holes 2 are provided at intervals of 140 mm. This is matched to the size of the vegetables grown during the first inter-strain adjustment (cultivation day 10). The adjacent interval of the second time (cultivation 20th day) is 280 mm, which is an interval that can sufficiently secure the size of the vegetables in the harvest period. Thus, according to the growth control of the vegetable to grow and the size of the vegetable to ship, it sets considering the space | interval of a plant fixing hole.

The inter-strain adjustment process in cultivation is shown in FIG. The state isolate | separated from the laminated cultivation panel 100 with which the four cultivation panels 1 were laminated | stacked is shown in FIG. About the hole space | interval of a cultivation panel, it shows in FIG.
In the fixed planting period, the seedling 5 having a size of 40 mm is planted on the laminated cultivation panel 100. The distance between the strains is 140 mm. 24 seedlings are planted in 24 plant fixing holes. In this example, it will be described as using seedlings that have been separately sown and raised. Although it is possible to directly sow on this laminated cultivation panel, there is a probability that poor germination and poor growth will occur, so it is reasonable to carry out the seedling raising in a separate process in consideration of the yield of the harvest. Since the seedlings have long roots, even the seedlings planted in the plant fixing holes 2 of the stacked upper panel can sufficiently reach the cultivation solution.
The first inter-strain adjustment is performed 10 days after planting. The cultivation panel AB placed above the laminated cultivation panel is separated and placed on the cultivation bed, and the cultivation becomes two sets of the cultivation panel AB and cultivation panel CD in which 12 strains are planted. Become. Vegetables grow to a size of 140 mm. The vegetables in the diagonal direction become adjacent strains, and a 200 mm strain is secured.
The second inter-strain adjustment is performed 10 days after the first inter-strain adjustment (cultivation 20th day). At the time of inter-strain adjustment, the vegetables have grown to a size of 200 mm.
The set of cultivation panel AB and cultivation panel CD is isolate | separated, respectively, and four cultivation panels are expand | deployed by the cultivation bed, and a cultivation area is further doubled. Six strains are planted in each cultivation panel. Between the stocks, 280 mm in length and width is secured.
Then it is cultivated for 10 days and harvested. Since the size of the vegetables in the harvest period is assumed to be 240 mm, a sufficient space between the plants is secured.

FIG. 6 schematically shows the use of the cultivation bed.
The cultivation bed 6 takes an example of a type in which a simple cultivation solution is stored and circulated. The cultivation bed 6 has a size corresponding to four pieces of the cultivation panel 1 and can manage the solution for each cultivation panel.
FIG. 6 shows a situation where a large cultivation area is required according to the inter-strain adjustment. At the time of planting, the area on which the laminated cultivation panel 100 is placed, that is, the area for one cultivation panel is used, the cultivation area becomes two cultivation panels by the first inter-strain adjustment, and the cultivation area by the second inter-strain adjustment Will increase to 4 cultivation panels.

FIG. 7 shows an example in which cultivation is performed in a cycle.
In this example, when using the four cultivation panels 1 laminated | stacked and the cultivation bed 6 of the magnitude | size for four sheets, it has shown that it can cycle with two cultivation beds.
In the first cultivation bed 61, one section is used for raising seedlings, the second section is used for planting, and 34 sections are used for the first inter-strain adjustment. The four sections of the second cultivation bed 62 are used for the second inter-strain adjustment. This makes it possible to cycle with two cultivation beds.
Furthermore, the generation of the fixed planting period, the generation of the first inter-strain adjustment period, the generation of the second inter-strain adjustment period, and the third generation can be cycled in two cultivation beds on the ABCD laminated cultivation panel.
In this example, the description is divided into two stages, but if a bed with a length of 8 panels is used, it can be shifted from left to right every 10 days. When planting is increased to 2 or 3, long cultivation beds are required.

8 and 9 are diagrams showing examples of inter-strain intervals.
4 and 5, as described for the growth of leafy vegetables and inter-strain adjustment, examples of inter-strain intervals in this embodiment are shown in FIG. 8.
In this cultivation panel, the plant fixing holes are spaced by 140 mm vertically and horizontally, and the plant fixing holes in the oblique direction are spaced by approximately 200 mm. This 140 mm interval corresponds to the size of the vegetables during the first inter-strain adjustment from the time of first planting. 200 mm is a size that can absorb the size of the vegetable grown between the first stock adjustment and the second stock adjustment. Further, after the second inter-strain adjustment, an interval of 280 mm, which is 140 mm × 2, is secured, and the size of the vegetables in the harvest period can be sufficiently absorbed.
Since this inter-strain interval is set according to the type of vegetable to be cultivated, the size of the fixed planting period, and the size of the inter-strain adjustment time, it is not specified in this interval.
The plant fixing hole provided in this cultivation panel has a diameter of 25 mm, and the plant passage hole has a diameter of 120 mm. Needless to say, leafy vegetables can pass through even if the plant passage hole is small. In the case of this example, the plant passage hole can pass if it has a diameter of 60 mm or more.
And in the cultivation panel of 900x600mm (actual size is 890x590mm), it is the size which is provided with 24 holes for plant fixation. Six seedlings will be planted on the cultivation panel, and six plant fixing holes and 18 plant passage holes will be provided. Alternatively, when harvesting is performed by adjusting the strain once, 12 plant seedlings are planted on one cultivation panel, so there are 12 plant fixing holes and 12 plant passage holes. It becomes the cultivation panel provided.

<Embodiment 2>
An example of a cultivation panel with a handle is shown in FIG.
In this example, the position of the handle 7 is changed by four cultivation panels to be combined.
Drawing (a) has shown the state where four cultivation panels were laminated. There are handles on both sides of the cultivation panel. The handle 7 is provided with base handles 71 and 73 and distinctive handles 72 and 74. In the example shown in the figure, four types of distinctive handles 72abcd and 74abcd in which the installation positions of the handles are shifted are used. Hold the base handle with the left hand, hold the distinguishing handle with the right hand, and lift and shift. It is possible to do it without making a mistake with a pair of two people.
This base handle can also be picked up automatically by attaching it as a distinction handle and can be made into an apparatus.
