A plant can be appropriately cultivated by satisfy | filling at least 3 conditions among (5).
[Condition (1): Temperature]
In the growth of plants, management of the growth temperature and growth humidity is an important environmental factor for controlling the growth rate and the size of the plant.
In this embodiment, the growth temperature of the plant inside the container 2 is set to a range of 3 to 30 ° C. For example, since mushrooms grow in the process of sprouting, generation, and growth, the inside of the container 2 is appropriately maintained at an appropriate temperature by the temperature control device 10 in each process.
[Condition (2): Humidity]
In this embodiment, the growth humidity of the plant inside the container 2 is set to a range of 75 to 100%. As with the growth temperature, the humidity inside the container 2 is maintained at an appropriate humidity by the humidity controller 20 as appropriate during the growth process.

[Condition (3): Illuminance]
The illuminance of light is an environmental factor greatly related to the promotion of plant growth and the suppression of growth.
The illuminance of light applied to the plant is in the range of 50 to 1000 Lux.
In order to give the plant the illuminance of light exposed in the natural environment, the light irradiation device 30 irradiates the plant with light. By irradiating the plant with light, growth can be promoted. On the other hand, for example, in enokitake mushroom growth, the light irradiation is performed and the suppression treatment is performed, so that the growth can be aligned and the productivity can be increased.
Since the time for irradiating light and the time interval for irradiating light vary depending on the type of plant and the growth stage, it is preferable to irradiate for a predetermined time as appropriate. By appropriately managing the time and interval of irradiating light, the quality of the plant is improved.

[Condition (4): Carbon dioxide concentration]
The carbon dioxide concentration is an environmental factor necessary for plant growth because, for example, when a high concentration of carbon dioxide is exposed in the growth stage of oyster mushrooms, the carbon dioxide concentration can grow into a target form. The carbon dioxide concentration inside the container 2 is 1000 to 3000 ppm. The carbon dioxide concentration can be adjusted by operating the gas concentration control device 40 and the vent 6.
For example, when the carbon dioxide concentration inside the container 2 becomes lower than a set value due to opening and closing of the door of the container 2 during work, carbon dioxide is supplied from the supply unit. Thereby, the carbon dioxide density | concentration inside the container 2 can be raised and the inside of the container 2 can be maintained at the target density | concentration. On the other hand, for example, when carbon dioxide is discharged due to plant metabolism, the carbon dioxide concentration inside the container 2 becomes higher than the set value. In this case, the carbon dioxide concentration inside the container 2 can be lowered by opening the ventilation port 6 and exchanging the air inside and outside.

[Condition (5): Air circulation speed]
The air circulation speed is set in the range of 0.1 to 1.0 m / s. The air circulation can be managed by the air circulation device 50. By circulating the air inside the container 2, it is possible to prevent a specific gas from staying locally, and to make the entire inside of the container 2 a uniform environment.
In particular, when the environmental factor is changed, air is circulated in the container 2 so as to be filled with the environmental factor.

By managing the environmental factors of the conditions (1) to (3) described above, the growth rate of the plant can be increased and the production amount can be increased. Furthermore, by using the environmental control device 60 and increasing the frequency of management of environmental factors, the growth rate and production amount of plants can be further improved, and plants can be cultivated efficiently.

As described above, the present embodiment has been described, but besides this, as long as it does not depart from the gist of the present invention, a part of the configuration mentioned in the above embodiment may be selected or changed to another configuration as appropriate. Is possible. For example, although the present embodiment has been described for mushrooms, it can also be applied to other plants such as white asparagus. Further, the environment control device 60 can be provided with a photographing unit. By observing the image of the photographing unit, the growth stage of the plant can be confirmed. Furthermore, it is possible to manage environmental factors in the long term or short term by creating a program.
