摘要

Provided are: a method for raising leaf-and-stem vegetables with which production cost is reduced and leaf-and-stem vegetables of high commercial value can be produced by irradiating the light necessary for growth on the leaf-and-stem vegetables efficiently; and a light source device for raising leaf-and-stem vegetables to be used in said growing method. A method for raising leaf-and-stem vegetables by irradiating light, the method being provided with a stem growth-inhibiting period for irradiating light from a stem growth-inhibiting light source with a high blue component, which inhibits stem growth, on the top of the stems at least during the initial growth period in which the stem sections and leaf sections can be distinguished.
