Plant cultivation method and plant cultivation equipment

Abstract

Provided is a plant cultivation method that is simple and energy efficient, and uses artificial lighting, which has an excellent growth-promoting effect, said plant cultivation method involving promoting the growth of plants by separately and independently carrying out, in fixed time periods, a step S1 in which a red illumination light is applied to plants, and a step S2 in which a blue illumination light is applied to the plants. In the plant cultivation method, a very prominent plant growth-promoting effect can be obtained using a simple technique in which red illumination light and blue illumination light are alternately applied.

Description

technical field [0001] The invention relates to a plant cultivation method and a plant cultivation device. In more detail, it is related with the plant cultivation method etc. which irradiate artificial light to a plant and promote preferable growth. Background technique [0002] Conventionally, in plant cultivation, a technique of irradiating plant seedlings with artificial light to promote seedling growth has been employed. By promoting the growth of plants, it is possible to shorten the cultivation time and increase the number of harvests in the same place. In addition, even with the same cultivation time, as long as the plants can be grown larger, the yield can be increased. [0003] As a plant cultivation method using irradiation of artificial light, for example, Patent Document 1 discloses a plant irradiation device configured to alternately irradiate plants with green light and white light. The irradiation device alternately irradiates green light with a wavelength...

Problems solved by technology

However, in Patent Document 2, in the comparison of irradiating blue light alone, irradiating red light alone, and irradiating blue light and red light simultaneously, it was confirmed that under simultaneous irradiation, the same healthy growth as cultivation under sunlight (unhealthy growth such as excessive growth in single irradiatio
