The heights H1, H2, H3, and H4 of the ground space 4 are gradually increased along the row direction K described above in each of a plurality of parallel longitudinal sections of the hydroponic cultivation device 15. Therefore, the hydroponic cultivation apparatus 15 has the ground space 4 suitable for the length in the vertical direction of each of the plurality of plant bodies 8s, 8m, 8l, and 8xl.

  According to the configuration as described above, the ground space 4 has no useless portions. Therefore, it is possible to grow a plurality of plant bodies 8s, 8m, 8l, and 8xl having different heights of the above-ground parts (stems and leaves) by efficiently using the above-described ground space 4.

  Hereinafter, the hydroponic cultivation apparatus 15 of this Embodiment is demonstrated in detail.

  The cultivation space contained in the cultivation room housing 10 is divided into two spaces arranged in the vertical direction by the plant support unit 1. Specifically, the cultivation room housing 10 includes a cultivation room ground part 11 that covers the ground space 4 and a cultivation room underground part 12 that covers the underground space 3.

  The cultivation room ground part 11 includes a rectangular flat plate-like ceiling part 11b parallel to a horizontal plane, and four side wall ground parts 11a extending vertically downward from four sides of the ceiling part 11b. The cultivation room basement 12 includes a rectangular flat bottom 12b that is inclined with respect to a horizontal plane, and four side wall bases 12a that extend vertically upward from four sides of the bottom 12b.

  Actually, the four side wall ground portions 11a are respectively connected to the four side wall underground portions 12a. That is, the hydroponic cultivation apparatus 15 has a space surrounded by four flat side walls.

  In the present embodiment, the hydroponic cultivation apparatus 15 shown in FIG. 1 is, for example, a triangular base, that is, a triangular prism base, and one side surface thereof is placed parallel to the horizontal plane. A table is inserted below the hydroponics device 15 and supported by the table. Therefore, the ceiling part 11b shall be parallel to a horizontal surface.

  In the cultivation room housing | casing 10, the plant support part 1 is fixed to the center position of each height direction of the above-mentioned four side wall parts, and functions as a member which partitions the cultivation room ground part 11 and the cultivation room basement part 12 into each other. doing. However, in the hydroponic cultivation apparatus of the present invention, the plant support 1 may be suspended from the ceiling 11b by a suspension member, for example. Moreover, in the hydroponic cultivation apparatus of this invention, the plant support part 1 may be supported by the pillar member in which the bottom part 12b is extended in a perpendicular direction, for example. That is, the plant support part 1 may be attached to any part of the cultivation room housing 10 as long as it can fix the positions of the plurality of plant bodies 8s, 8m, 8l, and 8xl.

  In the present embodiment, an example is shown in which four plants are supported by the plant support unit 1 in one row. However, as long as a plurality of plants having different sizes are supported by the plant support unit 1, the number of the plurality of plants in one row is not limited to four, and may be any value.

  The cultivation room ground part 11 comprises the housing | casing of the ground space 4 in which the ground part of several plant bodies 8s, 8m, 8l, and 8xl grows. The cultivation room underground part 12 constitutes a housing of the underground space 3 in which the underground parts of a plurality of plant bodies 8s, 8m, 8l, 8xl grow. The plant support unit 1 has a plurality of nutrient solutions sprayed from the nutrient solution supply unit 5 provided on the bottom 12b so that the roots of the plurality of plant bodies 8s, 8m, 8l, and 8xl in the underground space 3 can be absorbed. The plant bodies 8s, 8m, 8l and 8xl are supported. In addition, the plant support unit 1 includes a plurality of plant bodies 8s, so that the light emitted from the light source 9 provided on the ceiling part 11b is irradiated to the ground parts of the plurality of plant bodies 8s, 8m, 8l, 8xl. 8m, 8l, 8xl are supported.

  The plant support portion 1 includes an upper plane 1u as an upper surface thereof. The ceiling part 11b includes a lower flat surface 11bl as its lower surface. The upper plane 1u of the plant support portion 1 is inclined with respect to the lower plane 11bl of the ceiling portion 11b, that is, is inclined with respect to the horizontal plane. Therefore, as shown in FIGS. 1 and 2, in the present embodiment, the heights H1, H2, H3, and H4 of the ground space 4 increase in a linear function along the column direction K described above. Yes. Thus, according to the hydroponic cultivation apparatus 15 of the present embodiment, the height of the ground space 4 is aligned along the column direction K with a very simple configuration in which the ground space 4 is formed by two planes that are inclined to each other. Are different.

  The plant support 1 includes a lower flat surface 11 as its lower surface. The bottom portion 12b includes an upper plane 12bu as its upper surface. Further, the lower plane 11 of the plant support 1 and the upper plane 12bu of the bottom 12b are inclined at different angles with respect to the horizontal plane. In other words, in the present embodiment, the heights D1, D2, D3, and D4 of the underground space 3 are increased linearly along the column direction K described above. Thus, according to the hydroponic cultivation apparatus 15 of the present embodiment, the height of the underground space 3 is set along the column direction K with a very simple configuration in which the underground space 3 is formed by two planes that are inclined to each other. Are different.

  Further, the distances S1, S2, and S3 between the plurality of plant bodies 8s, 8m, 8l, and 8xl are made different so as to correspond to the occupied areas in the plan view of the plurality of plant bodies 8s, 8m, 8l, and 8xl. It is desirable. By doing so, it becomes possible to increase the planting density of the plurality of plants 8s, 8m, 8l, 8xl in the hydroponic cultivation apparatus 15.

  In addition, the above-described configuration “the heights D1, D2, D3, and D4 of the underground space 3 are gradually increased along the column direction K in the plant support portion 1” is the bottom plane 1l and the bottom portion of the plant support portion 1. Even if any one of the upper planes 12bu of 12b is a curved surface, it can be realized.

  In addition, the above-described configuration “the heights H1, H2, H3, and H4 of the ground space 4 are such that the plant support portion 1 gradually increases along the column direction K” includes the upper plane 1u and the ceiling portion of the plant support portion 1. Even if any one of the lower planes 11bl of 11b is a curved surface, this can be realized.

  A light source 9 for irradiating light to the plurality of plant bodies 8s, 8m, 8l, 8xl is provided on the lower surface 11bu of the ceiling part 11b. One light source 9 may be provided on the ceiling portion 11b, but in order to bring the conditions of light irradiation to each of the plurality of plants close to the same state as much as possible, the plurality of light sources 9 are arranged in a plan view. It is desirable that the direction K be provided along an imaginary line projected on the ceiling portion 11b. Furthermore, it is desirable that the plurality of light sources 9 are provided corresponding to the plurality of plant bodies 8s, 8m, 8l, and 8xl, respectively. More simply, it is desirable that the plurality of light sources 9 are respectively provided at positions vertically above the plurality of plant bodies 8s, 8m, 8l, and 8xl of the ceiling portion 11b.

  If a plurality of light sources 9 are arranged as described above, other members are required for adjusting the installation positions of the plurality of light sources 9 according to the sizes of the plurality of plant bodies 8s, 8m, 8l, and 8xl. And not. In addition, when the cultivation room ground part 11 is formed of a transparent member such as glass, the light source 9 may not be provided on the ceiling part 11b.

  As shown in FIG. 1, the nutrient solution discharge part 6 is provided at the lowest position of the bottom part 12 b in the bottom part 12 b of the cultivation room basement part 12 where the upper plane 12 bu is inclined. Therefore, all nutrient solution can be efficiently discharged | emitted from the cultivation room basement part 12 using gravity. According to this, the pump for discharging | emitting a nutrient solution from the cultivation room underground part 12 becomes unnecessary.

  Next, a method of cultivating a plurality of plant bodies 8s, 8m, 8l, 8xl using the hydroponic cultivation apparatus 15 of the present embodiment will be specifically described.

  In the present embodiment, the position at which each of the plurality of plant bodies 8s, 8m, 8l, 8xl is supported by the plant support unit 1 depends on the size of each of the plurality of plant bodies 8s, 8m, 8l, 8xl. Determined. Therefore, a plurality of plant bodies 8s, 8m, 8l, and 8xl can be grown in a cultivation space of an appropriate size according to each growth stage.

  For example, when the plurality of plant bodies 8s, 8m, 8l, and 8xl are a plurality of perennial plants, the plurality of plant bodies 8s, 8m, 8l, and 8xl are from those having a small age along the column direction K. They may be arranged in order from the largest. According to this, since a perennial plant has a high probability of height increasing in proportion to age, positioning of a plurality of plant bodies 8s, 8m, 8l, and 8xl is performed by using the age of each plant body as a reference. It can be done uniformly. That is, the operation of positioning each of the plurality of plant bodies 8s, 8m, 8l, and 8xl while confirming the respective heights becomes unnecessary. Therefore, the position of the plurality of plant bodies 8s, 8m, 8l, and 8xl can be easily determined.

  Perennial plants grow gradually over a long cultivation period. Therefore, if the size of the space in the hydroponic cultivation apparatus is ensured in accordance with the size of the final form of the perennial plant body, the wasteful space is very large at the initial stage of cultivation. However, when the internal space of a plant factory or the like is small, it is desired to plant a group of plants at a high density in the small space.

  According to said hydroponic cultivation apparatus 15, a relatively small plant body and a relatively large plant body can be arrange | positioned in the position which has the space of the magnitude | size suitable for each. Therefore, hydroponics can be performed by efficiently using a limited small space from the initial cultivation stage to the final cultivation stage of each plant body.

  In general, in order to plant a group of plants at a high density, a method of preparing a plurality of cultivation rooms having a cultivation space according to the size of each group of plants can be considered. However, according to the method, the operation | work which moves a plant body from one cultivation room to another cultivation room according to the growth of a plant body is needed. Therefore, it is necessary to take out the plant body in one cultivation room housing | casing outside, and to install the taken out plant body in another cultivation room housing | casing. Therefore, not only does it take a lot of time and effort to move the plants between the cultivation rooms, but also the possibility of damaging the plants.

  On the other hand, if the hydroponic cultivation apparatus 15 is used, a plurality of plant bodies can be obtained in a cultivation space corresponding to the size of each of the plurality of plant bodies by simply transferring the plant bodies in one cultivation room housing 10. Can be cultivated. Therefore, it is possible to reduce labor for moving the plant body, and to reduce the possibility of damaging the plant body during the transfer of the plant body.

  As described above, the hydroponic cultivation device 15 is suitable for the cultivation of perennial plants. An example of a perennial plant is ginseng (Ginseng or Ginseng). In the case of ginseng, the one with a cultivation period of about 1 year corresponding to the smallest plant body 8s has a height of about 10 cm, and the one with a cultivation period of about 4 years corresponding to the largest plant body 8xl. It has a height of about 60 cm. Therefore, the hydroponic cultivation apparatus 15 according to the present embodiment includes the underground space 3 and the ground space 4 having a size suitable for cultivating a plant body of that size. However, in this invention, the magnitude | size of the underground space 3 and the above-ground space 4 changes according to the magnitude | size of the final form of the plant body to be cultivated.

  Although the material of the above-mentioned plant support part 1 is not specifically limited, It is desirable to use a polystyrene foam or resin.

  As a method for supplying the nutrient solution to the plant body, in the present embodiment, a method of spraying mist toward the root of the plant body is used. However, any method such as a method in which a nutrient solution cloth containing a nutrient solution is brought into contact with the root of the plant body or a method in which the root of the plant body is immersed in the nutrient solution stored in the underground space can be used in the hydroponics of the present invention. It can be applied to the device.

  In the case of a system in which mist is sprayed, the nutrient solution supply unit is a mist discharge port and a structure associated therewith. When storing the nutrient solution in the underground space, a nutrient solution flow path for supplying the nutrient solution to the underground space and a structure associated therewith are the nutrient solution supply unit. When supplying the nutrient solution to the plant body by bringing the nutrient solution cloth containing the nutrient solution into contact with the underground part (root) of the plant body, there is a door for putting the material containing the nutrient solution into the underground space. It becomes a nutrient solution supply unit for supplying nutrient solution to the underground part (root) of the plant body.
