Abstract

A plant cultivation method is provided, including: a sequence of irradiating a plant with sunlight; a sequence of irradiating the plant with red light; and a sequence of irradiating the plant with blue light, in which the sequences are performed independently within a certain period of time. A plant cultivation apparatus is also provided, including: a region in which a plant is irradiated with sunlight; a light irradiation unit that irradiates the plant with artificial light including red light and/or blue light; and a control unit that controls the light irradiation unit to independently perform a step of irradiating a plant with red light and a step of irradiating the plant with blue light.

Claims

1. A plant cultivation method comprising:

a sequence of irradiating a plant with sunlight;

a sequence of irradiating the plant with red light; and

a sequence of irradiating the plant with blue light,

wherein the sequences are performed independently within a certain period of time.

3. The plant cultivation method according to claim 1,

wherein the sequence of irradiating the plant with red light is performed subsequently to the sequence of irradiating the plant with sunlight.

4. The plant cultivation method according to claim 1,

wherein the sequence of irradiating the plant with blue light is performed subsequently to the sequence of irradiating the plant with sunlight.

5. The plant cultivation method according to claim 1,

wherein the sequence of irradiating the plant with sunlight is performed subsequently to the sequence of irradiating the plant with red light.

6. The plant cultivation method according to claim 1,

wherein the sequence of irradiating the plant with sunlight is performed subsequently to the sequence of irradiating the plant with blue light.

2. A plant cultivation method comprising:

a sequence of irradiating a plant with sunlight; and

a sequence of irradiating the plant with artificial light when the sunlight is insufficient,

wherein in the sequence of irradiating the plant with artificial light, a sequence of irradiating the plant with red light and a sequence of irradiating the plant with blue light are performed independently within a certain period of time.

7. A plant cultivation apparatus comprising:

a region in which a plant is irradiated with sunlight;

a light irradiation unit that irradiates the plant with artificial light including red light and/or blue light; and

a control unit that controls the light irradiation unit to perform independently a step of irradiating the plant with red light and a step of irradiating the plant with blue light within a certain period of time.
