The positioning parts (5, 6 and 7) indicated by reference numerals 5, 6 and 7 constitute a laminating means for fitting and laminating a plurality of cultivation containers 1 when they are laminated.

  The cultivation room 3 includes a bottom surface part 8 formed as a bottom surface of a cultivation room recess whose upper side is open, and a positioning part (5, 6 and 7) formed as a stacking means formed from the periphery of the opening part 4 to the cultivation room recess inner surface. ).

  In addition, the outer surface shape of the lower convex part 3a of the back surface side (outer surface side) corresponding to the concave part of the cultivation room 3 is formed in a tapered shape whose sectional area gradually decreases in the depth direction. However, the fitting convex portions 6a1 and 7a1 shown in FIG. 2 may be provided perpendicular to the plane of the plane portion 2.

  The bottom surface portion 8 includes a convex portion 9 that is a cross shape in a plan view and that protrudes into a ridge shape, and a plurality of water passage holes 10 that are formed in the upper surface portion of the convex portion 9. A plurality of '-'s corresponding to the cross-shaped horizontal axis (short axis) may be provided at intervals. The bottom surface portion 8 will be described in detail with reference to FIG.

  In the present embodiment, a plurality of (for example, three) positioning portions (5, 6 and 7) are provided on the inner surface side around the opening 4 of the cultivation room 3 of each cultivation container 1.

  As shown in FIG. 1, the positioning portions (5, 6 and 7) are a set of concave steps facing each other provided to scrape the peripheral inner wall (inner surface side) of the opening 4 in the cultivation room 3. A recess 5, a fitting recess 6 provided in one stepped recess of the set of stepped recesses 5, and two provided on both end sides of the other opposed stepped recess of the set of stepped recesses 5. And a recess 7 for fitting. A set of stepped recesses 5 is an air circulation part that forms a gap that communicates with the external space without sealing the cultivation room 3 when the cultivation containers 1 are stacked one on top of the other and are stacked. Is functioning as

  When the positioning part (5, 6 and 7) stacks a plurality (for example, two) of the cultivation containers 1 in the vertical direction, the lower convexity corresponding to the cultivation room 3 of the one cultivation container 1 on the upper side. The lower end portion of the fitting convex portions 6a1, 7a1 (see FIG. 2) formed in a convex shape on the outer surface of the portion 3a (this is indicated by reference numeral 3a because it is the outer surface side of the concave portion forming the cultivation room 3) The other lower side of the cultivation container 1 is fitted into the concave recesses 6 and 7 formed in a concave shape in the upper part of the inner surface of the cultivation chamber 3, and a predetermined position in the depth direction (this is a set of stepped portions 5 It is for positioning (fixing) in contact with the horizontal position of the step portion. In addition, although the recessed parts 6 and 7 for fitting formed in the inner surface side of the cultivation room 3 appear as a part of the convex parts 6a1 and 7a1 for fitting on the outer surface side (back surface side) of the cultivation room 3, about this, FIG. And FIG. 3 demonstrates.

Here, various dimensions such as the outer shape of the cultivation container 1 will be described.
The cultivation container 1 is formed with a thickness of, for example, 1 mm, the size of the flat portion 2 (width × length) is, for example, 600 mm × 300 mm, and the size of the opening 4 of the cultivation room 3 is, for example, 130 mm × 65 mm. The vertical dimension (depth) L1 (see FIG. 3) of the cultivation room 3 is, for example, 50 mm. Moreover, the size of the bottom face part 8 of one cultivation room 3 is, for example, 120 mm × 60 mm. As the depth from the opening 4 to the bottom surface 8 of the cultivation room 3 increases, the inner wall surface of the recess gradually inclines (that is, becomes a taper gradient) so that the horizontal x vertical cross-sectional area is gradually reduced. It is the smallest size (area). In connection with this, the outer peripheral surface of the lower convex part 3a which is the outer surface side of the cultivation room 3 is also a tapered surface inclined in the depth direction. The reason why the tapered surface is inclined in this manner is to create a gap through which the air inside the cultivation room 3 is circulated even when the plurality of cultivation containers 1 are vertically fitted. This function as an air circulation part is particularly effective in combination with the above-described set of stepped recesses 5.

  FIG. 2 shows a perspective view of the cultivation room 3 as seen from the back side. That is, the lower convex part 3a of the back surface side corresponding to the cultivation room recessed part of the surface side of the cultivation room 3 is shown. FIG. 3 is a side view as seen from the outer surface side in one cultivation room 3.

  In FIG. 2, in order to represent the back side, for example, the back side concave portion corresponding to the front side convex portion 9 (FIG. 1) is indicated by reference numeral 9a. In order to prevent the bottom surface of the container from directly touching the floor surface, the ground or the like when placing the cultivation container 1 on the floor surface, the ground surface, or the like, the bottom surface portion 8 of the cultivation room 3 shown in FIG. (FIG. 1) is provided, and these concave portions 11 are shown as four convex portions 11a for the leg on the back surface side shown in FIG. The height of the leg protrusion 11a is, for example, 5 mm. Furthermore, on the outer surface side wall portion facing the outer surface side of the lower convex portion 3a on the back surface side (outer surface side) corresponding to the concave portion forming the cultivation room 3, the front surface side (inner surface side) recesses for fitting 6, 7 The fitting projections 6a1 and 7a1 corresponding to each are shown. As will be described with reference to FIG. 3, the depth of the fitting recesses 6 and 7 (FIG. 1) on the front surface side (inner surface side) is approximately L2 (≈15 mm), whereas the rear surface side (outer surface side). The depth of the fitting convex portions 6a1, 7a1 (FIGS. 2 and 3) is a length L1 (≈50 mm) substantially corresponding to the depth of the cultivation room 3, and the concave portions 6, 7 fitted to each other. The convex portions 6a1 and 7a1 have different heights on the inner surface side and the outer surface side.

  3A corresponds to the right side view of FIG. 2, and FIG. 3B corresponds to the left side view of FIG. 3 (a) and 3 (b), the height L1 of the outer shape of the cultivation room 3 is, for example, 50 mm, and the height L2 of the stepped recess 5a is, for example, 15 mm. The heights of the fitting convex portions 6a1 and 7a1 viewed from the outer surface side shown in FIGS. 3 (a) and 3 (b) are the same as L1.

  FIG.4 and FIG.5 demonstrates the state which laminates | stacks the two cultivation containers 1 up and down.

  FIG. 4 shows the correspondence of the fitting positions of the upper and lower cultivation containers 1U and 1D when two cultivation containers 1U and 1D are stacked one above the other. FIG. 5 shows a fitted state when two cultivation containers 1U, 1D are stacked one above the other from the state of FIG.

In the bean seedling cultivation container, two or more cultivation containers 1 are stacked vertically in the germination period after sowing as shown in FIG. In the stacked state of FIG. 5, the upper cultivation container 1U is indented and fixed (fixed) by a length L2 (for example, 15 mm) with respect to the lower cultivation container 1D. As a result, the two cultivation containers 1U, 1D The distance between the flat surface portions 2 is defined as L1-L2 (= 35 mm). That is, the cultivation space in a state where a plurality of cultivation containers are stacked is defined as a height space of about 35 mm. ,
Moreover, FIG. 6 (a) shows the top view of the bottom face part 8 seen from the surface side (inner surface side) of one cultivation room 3 in the cultivation container 1 shown in FIG. 1, FIG.6 (b) shows FIG. ) Is a cross-sectional view taken along line AA in FIG. 6, and FIG. 6C is a cross-sectional view taken along line BB in FIG.

  In FIG. 6 (a), the bottom surface portion 8 of the cultivation chamber 3 of the cultivation container 1 is formed in a cross shape in plan and has a predetermined height 9 for defining the water level of the cultivation liquid. And a plurality of (three in the figure) water holes 10 for draining excess cultivation liquid and circulating air, and the rear side (outer surface) of the cultivation room shown in FIG. And four substantially hemispherical concave portions 11 for projecting as leg convex portions 11a. The four leg projections 11a projecting to the back side shown in FIG. 2 pull the lower projection 3a away from the floor or ground when the cultivation container 1 is placed directly on the floor or ground. It is necessary to promote the drainage of excess cultivation liquid discharged from the water passage 10 to the outside and the circulation of air. The water passage hole 10 is a circular hole having a diameter (for example, 4 mm) smaller than the diameter of a substantially spherical seed (for example, peas) to be cultivated.

  In addition, even if the thickness of the material of the cultivation container is thin by forming the planar shape of the convex portion 9 in a cross shape, the strength against deformation such as bending can be increased and the planarity of the bottom surface portion 8 can be maintained. Since the bottom surface 8 is provided with the cross-shaped convex portion 9, an uneven portion is formed, so that roots grown from a plurality of seeds are easily entangled with each other in the process of germination and growth after seeding. There is also an advantage of becoming.

  According to the present invention described above, even a sprout vegetable that is relatively weak against heat, such as bean seedlings, and is susceptible to root rot in summer, etc., can be cultivated robustly without rot, and in productivity. It is possible to realize an excellent cultivation container.

  Next, the cultivation method of the bean seedling using the said cultivation container by this embodiment is demonstrated with reference to FIG. Here, the cultivation method of the bean seedling using the cultivation container 1 demonstrated in FIG. 1 thru | or FIG. 6 is demonstrated.

  The original bean seedlings were grown in the open field where the crops were cultivated under natural weather conditions, and the young leaves were eaten. However, the bean seedlings in hydroponics (nutritional solution) cultivation grow from the shape of the conventional cultivation container, and the stems grow slightly and the young leaves are slightly above the stem and eat the original young leaves. It was not. In order to improve this and grow a bean seedling, the present invention has developed a cultivation container having a new structure using a new material as a cultivation container. As a result, many young leaves were seen from the lower part to the upper part of the stem compared to the products of other companies, which led to obtaining an appropriate food for eating the young leaves.

  The cultivation container 1 is formed using a white or white opaque or translucent material that is divided into a plurality of cultivation rooms 3 and is integrally formed in a concave shape and reflects at least a part of external light. In addition, when the cultivation containers 1 are stacked in a plurality of layers, the cultivation containers 1 are provided with a stacking means for fitting and stacking the cultivation containers 1 with each other in units divided for each cultivation room 3. Furthermore, when the cultivation container 1 is laminated | stacked up and down, the clearance gap which connects the cultivation room 3 and the exterior (external space) is used as an air circulation part around the fitting part of the cultivation rooms corresponding to each other of the upper and lower cultivation containers. To be formed.

  As a cultivation method, first, pea beans, which are seeds of bean seedlings, are prepared and immersed in a container (not shown) containing water for a predetermined time (for example, 3 hours) to allow the seeds to absorb water.

  Next, as shown in FIG. 7, the seed 12 soaked in water is directly sown on the bottom surface portion 8 of each cultivation chamber 3 of the cultivation container 1. In FIG. 7, three cultivation containers 1U, 1M, and 1D are prepared in a plan to be stacked in three steps, and evenly placed so that the bottom surface is not visible in each cultivation room 3 of each cultivation container or doubled. Sowing.

Then, the three cultivation containers 1U, 1M, and 1D directly seeded with the seeds 12 are fitted with their fitting portions aligned as shown by the alternate long and short dash line in FIG. 7, and are stacked in the dark room as shown in FIG. (Not shown)
Thereafter, the three-tiered cultivation containers 1U, 1M, and 1D are placed in the darkroom for a predetermined period (for example, one week) for a predetermined period (for example, predetermined temperature and humidity), and germinate and grow. In addition, the said predetermined period is a germination period until it germinates and the cotyledon 13 comes out, and it is about 7 days in summer, and about 9 days in winter. The cotyledon 13 is whitish, and has a light yellow color.

  Next, as shown in FIG. 9, when the predetermined period is reached and the cotyledon 13 is grown, the three-tiered cultivation containers 1U, 1M, and 1D are exposed to outside light (for example, sunlight) from the darkroom. Move to a house using vinyl to enter. A glass room may be used instead of the greenhouse. When moving from the dark room to the house where external light enters, the cotyledon 13 is soft, and it is not preferable to radiate strong light immediately after leaving the dark room. It is preferable to adjust.

  And in the said house, the three-stage cultivation containers 1U, 1M, and 1D are divided and arranged one by one, and the cultivation liquid is used for each cultivation container 1U, 1M, and 1D using the sprinkler 20 as shown in FIG. Supply by spraying 21.

  Then, each cultivation container 1U, 1M, 1D to which the cultivation liquid 21 is supplied is installed and grown under predetermined growth conditions for a predetermined period (for example, one week). The seedlings grown in each cultivation room 3 are in a state where roots are intertwined in the process of growing a large number of seeds. Note that the predetermined period is a growth period from the state of the cotyledon 13 until the green young leaf 14 comes out, and the summer period is about 7 days and the winter period is about 9 days.

  During this growth period, external light enters the cultivation container through the white or white opaque or translucent cultivation container, and photosynthesis is easily performed. Therefore, a plurality of side branches emerge from the stem portion from which the cotyledon 13 has come out, and these side branches A young leaf 14 comes out and grows on each of a plurality of branches including

  Next, the seedlings grown for each cultivation room 3 in each cultivation container 1U, 1M, 1D are harvested as a bundle and packaged in a bag 30 such as polyethylene as shown in FIG. In order to harvest, if the seedlings grown in each cultivation room 3 are pulled out as a bundle with a stem portion, the root entanglement 15 is formed, so that it can be pulled out as a bundle.

  In the cultivation of bean seedlings, a medium is unnecessary and the germination period may be almost free of fertilizer. And when giving a fertilizer as a cultivation liquid in a growth period, it is preferable to spray the liquid of the appropriate concentration which made the density | concentration very thin from a seedling. When fertilizer is thick, it often causes over-nutrition and the seedlings fail.

  In addition, the present applicant cultivates and ships sprout (see Patent No. 2911111) treated with fungi (for example, lactic acid bacteria) on plants such as radishes, but this is suitable for bean seedlings. It is also possible to perform lactic acid bacteria treatment.

  According to the present invention described above, even a sprout vegetable that is relatively weak against heat, such as bean seedlings, and is susceptible to root rot in summer, etc., can be cultivated robustly without rot, and in productivity. It is also possible to provide a cultivation method using an excellent cultivation container.
