Abstract
In a plant cultivating apparatus for cultivating plants by using an artificial light source, partition walls having a high light reflectance are arranged in a cultivation area to divide the cultivation area into small spaces and in each small space a light-reflecting plate is arranged, and the distance between an artificial light source and a plant is narrowed to irradiate the plant with a light having a low illuminance. In accordance with a preferred embodiment, there is provided a plant cultivating apparatus comprising sets of pallets which have plants placed therein and are arranged in rows in a growing chamber where environmental conditions which are artificially controlled and which are moved in a direction radial to the row direction in accordance with the growth of plants, wherein all the peripheral surface of the growing chamber are covered with a reflecting plate having a high light reflectance. Low-illuminance artificial light sources for emitting a light of a low illuminance are arranged so that the distance between the light sources and plants are small, and the spaces between the rows of pallets are 1.1 to 1.5 times the spaces between plants provided when plants are closely set to such an extent that adjacent plants do not overlap each other.
