Moreover, the plant holder 30 that has flowed downstream pushes the adjacent plant holder 30, and the plant holder 30 also flows downstream. As a result, all the plant holders 30 floating in the nutrient solution tank 3 flow downstream.

Next, the function of the plant cultivation line 1 of this embodiment is demonstrated.
In the plant cultivation line 1 of the present embodiment, the nutrient solution tank 3 is filled with the culture solution. Therefore, there is a liquid level of the nutrient solution tank 3 in the cylindrical space 2, and the liquid level is covered with the cylindrical space 2. The plant seedling is held in the opening 31 of the plant holder 30 and floated on the upstream side of the nutrient solution tank 3.
The illumination means 27 supplies light required for seedling growth. In the present embodiment, since light is reflected by the inner surface of the cylindrical space 2, the light hitting the inner wall of the cylindrical space 2 is also reflected and hits the seedling.

Furthermore, the temperature, humidity, and carbon dioxide concentration in the cylindrical space 2 are adjusted by the growing space air-conditioning means 22 shown in FIGS.
As described above, the equipment installation chamber 110 that is the outside of the cylindrical space 2 is shielded from the outside (inside the structure 101), and the equipment installation room 110 is air-conditioned by the indoor air-conditioning means 113. 2 external environment (environment in the equipment installation room 110) is stable to some extent. Therefore, the cylindrical space 2 is not easily affected by the surrounding environment (environment in the structure 101) at the position where the plant cultivation apparatus 100 is installed.
Furthermore, since the inside of the cylindrical space 2 is air-conditioned by the growing space air-conditioning means 22, the inside of the cylindrical space 2 is kept at a temperature and humidity suitable for plant growth.

  The plant holder 30 floated in the nutrient solution tank 3 in the cylindrical space 2 is moved to the downstream side at regular time intervals. For example, every 24 hours, the plant holder 30 is pushed by human power, and the plant holder 30 is caused to flow downstream.

In the plant cultivation line 1, the plant holder 30 is sent from the beginning to the end over about 10 to 30 days. Here, the seedling held by the plant holder 30 grows with the passage of time, but in this embodiment, the height of the roof member 6 increases toward the downstream side. Therefore, the seedling can be appropriately illuminated without impeding the growth of the seedling. That is, the seedling height is low during the seedling season. In the present embodiment, the height of the roof member 6 is low on the upstream side, and the distance between the seedling and the illumination means 27 is short. Therefore, it is possible to irradiate light intensively to the seedling.
On the other hand, the height of the roof member 6 is high at the position where the seedling grows and becomes tall, and the seedling can be irradiated with light evenly.

Then, the plant holder 30 is taken out at the end of the plant cultivation line 1 and the grown plant is harvested, or the plant holder 30 is brought into another plant cultivation line 1 again to grow the seedling larger.
That is, the plant holder 30 in which seedlings are planted is inserted at the beginning of the plant cultivation line 1, the lighting means 27 is turned on to illuminate the leaves of the seedlings, and the culture solution in the nutrient tank 3 is absorbed from the roots of the seedlings. Let them grow seedlings. And the plant holder 30 which floats in the nutrient solution tank 3 is pushed, it is made to flow downstream, and the inside of the cylindrical space 2 is moved slowly.
Meanwhile, the seedlings are placed in an environment maintained at an appropriate temperature and humidity, and grow by receiving sufficient light from the lighting means 27.
When the plant holder 30 passes through the end of one plant cultivation line 1 or passes through a plurality of plant cultivation lines 1, the seedlings are grown to be used for food, Harvested from the tool 30 and shipped.

In the above-described embodiment, the plant cultivation line 1 floats a plurality of plant holders 30 in one nutrient tank and causes the plant holders 30 to flow and move downstream, but the present invention has this configuration. It is not limited, The thing of a structure provided with a some nutrient solution tank and moving a nutrient solution tank sequentially from an upstream to a downstream by a conveyance means may be sufficient.
