PRODUCTION METHOD OF LEAF VEGETABLES AND PRODUCTION DEVICE OF LEAF VEGETABLES

摘要

To provide a production method and a production device of leaf vegetables in which a temperature condition and a light quality condition are changed, for clarifying an environment control for increasing quantity of biosynthesis of folate salt, and leaf vegetables with high folate salt can be produced.SOLUTION: There is provided a RGB independent modulation light source plant cultivation device 1 for vegetables using water culture under an artificial illumination in which lights of red color, blue color and green color are controlled comprising: a light radiation part 5 for radiating a light to vegetables 3; and a control part 7 for controlling at least one of a ratio of lights of red color, blue color and green color radiated by the light radiation part 5, a photosynthesis effective photon flux density (PPFD) and a growth environment temperature for increasing density of folate salt.SELECTED DRAWING: Figure 1
