In the plant growing section 30 of the hydroponic cultivation apparatus 10, the case 310 as a cultivation tank in which the space S1 in which the taproot 61 as the underground part of the root vegetables 60 grows is formed, and the main root 61 of the root vegetables 60 are placed in the space S1. It is provided with a support portion 320, which supports the root vegetables 60 so as to be located.

In the present embodiment, the case 310 is made of a material that does not allow light to pass through, and the case 310 blocks light entering from the outside to the inside.

Further, the case 310 includes a substantially rectangular plate-shaped bottom wall portion 311 and a side wall portion 312 formed so as to rise upward from each side (peripheral portion) of the bottom wall portion 311. Is formed so that the space S1 in which the taproot 61 grows opens upward.

A substantially rectangular plate-shaped support portion 320 is arranged so as to close the opening of the case 310, and the plant growing portion 30 has a hollow rectangular parallelepiped shape as a whole.

The shape of the plant growing portion 30 is not limited to a hollow rectangular parallelepiped shape, and can be various shapes such as a hollow polygonal columnar shape and a cylindrical shape.

Further, the support portion 320 that closes the opening of the case 310 is made of a material that does not allow light to pass through, such as styrofoam, and the support portion 320 blocks light that enters from the outside to the inside. Then, the root vegetables 60 are supported by the support portion 320 in a state where the taproot 61 is located in the space S1.

In the present embodiment, the support portion 320 is provided with the medium 322 so that the taproot 61 is held in the medium 322. By doing so, the root vegetables 60 are supported by the support portion 320. Specifically, the support portion 320 is formed with a through hole 321 penetrating in the plate thickness direction, and the medium 322 is provided in the through hole 321.

The medium 322 can be formed, for example, with a sponge, that is, urethane foam. In this way, the medium 322 can be elastically deformed according to the growth of the taproot 61 of the root vegetables 60.

In the present embodiment, the medium 322 has a cylindrical shape with a through hole formed in the center. Then, in a state where the root vegetables 60 are supported by the support portion 320, the medium 322 is a part of the root vegetables 60 between the inner peripheral surface of the through hole 321 formed in the support portion 320 and the outer peripheral surface of the taproot 61. It is provided so as to surround the. At this time, the root vegetables 60 are supported by the frictional force generated between the sponge medium 322 and the taproot 61.

Further, in the present embodiment, a plurality of through holes 321 are formed in the support portion 320, and a medium 322 is formed in each through hole 321.

That is, in the present embodiment, a plurality of root vegetables 60 (main root 61 of the root vegetables 60) are supported by one support portion (common support portion) 320. Therefore, in the present embodiment, a plurality of (two or more) root vegetables 60 are supported in one plant growing unit 30 in a state where each taproot 61 is located in the space S1. In addition, one root vegetable 60 (the taproot 61 of the root vegetable 60) may be supported by one support portion 320.

Further, the hydroponic cultivation apparatus 10 includes a mist spraying unit (mist supply unit) 41 for supplying the nutrient solution L to the taproot 61 of the root vegetables 60 by spraying the nutrient solution L. Then, when hydroponics is carried out, the nutrient solution L is supplied to the taproot 61 located in the space S1. As described above, the hydroponic cultivation apparatus 10 according to the present embodiment grows the root vegetables 60 by irradiating the leaves 64 of the root vegetables 60 with light and supplying the nutrient solution L to the taproot 61.

Specifically, the hydroponic cultivation device 10 is connected to the mist spraying unit 41 described above, the nutrient solution storage tank (nutrient solution storage unit) 70 for storing the nutrient solution L, and the mist spraying unit 41 for feeding. A nutrient solution pipe (nutrient solution supply unit) 40 for supplying the nutrient solution L in the liquid storage tank 70 to the mist spray unit is provided. Further, the hydroponic cultivation device 10 is provided with a drainage pipe (nutrient solution discharge unit) 50 which is connected to the case 310 and discharges the nutrient solution L in the case 310 and returns it to the nutrient solution storage tank 70. There is.

As described above, in the present embodiment, the mist M of the nutrient solution L is supplied to the taproot 61 while circulating the nutrient solution L in the nutrient solution storage tank 70.

The mist M of the nutrient solution L is supplied to the taproot 61 by a pump 80 arranged in the nutrient solution storage tank 70 and continuously provided at the upstream end of the nutrient solution pipe 40.

As the pump 80, for example, a submersible pump can be used. When the pump 80 is used to feed the liquid to the nutrient solution pipe 40, it is preferable that each plant growing unit 30 can uniformly feed the liquid.

Further, in the present embodiment, one nutrient solution pipe 40 is illustrated in which one nutrient solution pipe 40 is arranged from each side wall portion 312 in a plurality of plant growing portions 30 (in the space S1). Then, a plurality of mist spraying units 41 are continuously provided in one nutrient solution pipe 40 so as to correspond to the plurality of taproots 61 located in the space S1 of each plant growing unit 30, and each mist spraying unit 41. The mist M of the nutrient solution L sprayed from is supplied to the corresponding taproot 61.

The number of mist spraying portions 41 supplied to one taproot 61 and the number of spraying holes formed in one mist spraying portion 41 are not particularly limited, but are substantially equal to the entire taproot 61. It is preferable that a uniform mist M is sprayed. For example, it is preferable to arrange the mist spraying unit 41 so that the amount of mist M sprayed per unit time becomes substantially uniform at various parts of one taproot 61.

Further, it is preferable to control the spraying of the mist M from the mist spraying unit 41 so that a fixed amount of the mist M can be sprayed at regular intervals. The control of spraying mist M from the mist spraying unit 41 is not limited to a predetermined method. However, at least, it is preferable that the spray pressure or the amount of spray that can more uniformly apply the nutrient solution L to the root vegetables 60 can be adjusted, and the spray timing of these can be controlled.

As such control, for example, control for switching on / off of spraying at 15-minute intervals can be considered all day long. That is, it is conceivable to control the spray pressure or spray amount of mist M capable of more uniformly applying the nutrient solution L to the root vegetables 60 to the taproot 61 all day at 15-minute intervals.

Further, the method of arranging the nutrient solution pipe 40 and the mist spraying unit 41 is not limited to the above-mentioned method, and can be arranged by various methods. For example, the nutrient solution pipe 40 may be branched into a plurality of pipes on the downstream side of the pump 80, and each of the branched pipes may be arranged in the corresponding plant growing unit 30. Further, a plurality of sets of the pump 80 and the nutrient solution pipe 40 may be prepared, and the nutrient solution pipe 40 of each set may be arranged in the corresponding plant growing unit 30. The nutrient solution pipe 40 and the mist spraying portion 41 are preferably arranged at positions where interference with the growing taproot 61 can be suppressed.

Further, in the present embodiment, the nutrient solution storage tank 70 is provided separately from the plant growing section 30, but the nutrient solution storage tank 70 and the plant growing section 30 can be integrated. ..

One end of the drainage pipe 50 is connected to a connecting hole 311a formed in the bottom wall portion 311 of the case 310, and drainage flows down into the nutrient solution storage tank 70 from the other end. .. That is, the nutrient solution L that has fallen on the bottom wall portion 311 of the case 310 is returned to the nutrient solution storage tank 70 through the drainage pipe 50.

The nutrient solution pipe 40 and the drainage pipe 50 may be made of a hose made of flexible rubber, or may be made of a hard pipe such as a vinyl chloride pipe.

Then, if the root vegetables 60 are grown using the hydroponic cultivation apparatus 10 having the above-described configuration, it is possible to prevent the roots (taproot 61 and side roots 62) of the root vegetables 60 from being immersed in the nutrient solution L for a long time. .. As a result, the generation of bacteria in the immersed portion and the generation of putrefaction due to lack of oxygen are suppressed, and the root vegetables 60 can be cultivated more soundly.

Then, the root vegetables 60 grown using the hydroponic cultivation device 10 are harvested from the hydroponic cultivation device 10 when they have grown to some extent. The root vegetables 60 harvested from the hydroponic cultivation apparatus 10 are utilized, for example, as seedlings for fields.

In this way, when the root vegetables 60 cultivated by the hydroponic cultivation device 10 are used as seedlings for the field, the root vegetables 60 harvested from the hydroponic cultivation device 10 are carried to the field and planted in the field. Will be.

The root vegetables 60 can be harvested from the hydroponic cultivation apparatus 10 at the timing when the above-ground parts (stems 63 and leaves 64) die, for example. However, since there are individual differences in the growth of the root vegetables 60, the root vegetables 60 whose above-ground parts have died and the root vegetables 60 whose above-ground parts have not died at the time of harvesting from the hydroponic cultivation device 10 are mixed. It is expected to be (see FIG. 3). Therefore, when there is a difference in the growth of the root vegetables 60, the root vegetables 60 whose above-ground part has died and the root vegetables 60 whose above-ground part has not died will be harvested from the hydroponic cultivation apparatus 10.

Here, when the root vegetables 60 cultivated by hydroponics are used as seedlings for the field, it is necessary to reduce the stress during transportation so that they can be cultivated soundly even after planting in the field. ..

The stress during this transportation is generally dryness. Then, as a method of protecting the root vegetables 60 from drying during transportation, it is conceivable to use a gel-like substance and insert the underground portions 61 and 62 of the root vegetables 60 into the gel-like substance for transportation.

Further, when the root vegetables 60 cultivated by hydroponics are transported to the field, it is particularly important to transport the underground portions 61 and 62 of the root vegetables 60 to the field while protecting them from stress.

Normally, since the underground portions 61 and 62 of the root vegetables 60 are covered with soil, light as well as drying causes stress during transportation.

However, as described above, the underground portions 61 and 62 of the root vegetables 60 can be protected from the drying stress during transportation by simply inserting the underground portions 61 and 62 into the gel-like substance and transporting the root vegetables 60. Underground parts 61 and 62 cannot be protected from light stress during transportation.

If the underground portions 61 and 62 are exposed to light during the transportation of the root vegetables 60, the growth of the underground portions 61 and 62 may be suppressed or the colors of the underground portions 61 and 62 may change. .. As a result, the root vegetables 60 may not be cultivated soundly after planting in the field.

Therefore, in the present embodiment, the root vegetables 60 grown in the hydroponic cultivation device 10 are transported by using the transport device 90 capable of protecting the underground portions 61 and 62 from the stress of light in addition to drying. I tried to do it.
