Claim 0:
1. A cultivation method for cultivating leaf vegetables, the cultivation method comprising:
preparing correspondence information associating light characteristic information indicative of a characteristic of light with which leaf vegetables are irradiated, with quantified quality information having a quantified quality of leaf vegetables;
setting the light characteristic information; and
irradiating the leaf vegetables with light,
wherein the preparing includes preparing the correspondence information for at least one quality of leaf hardness, leaf thickness, leaf color, sugar content Brix value, vitamin C, and antioxidant component content of the leaf vegetables,
the light characteristic information includes an integrated photosynthetic photon flux density of light, and
the setting includes setting a ratio between a photosynthetic photon flux density of the red light and a photosynthetic photon flux density of the blue light and setting a range of the integrated photosynthetic photon flux density in a manner that at least one quality of the leaf hardness, the leaf thickness, the leaf color, the sugar content Brix value, the vitamin C, and the antioxidant component content is constant regardless of a value of the integrated photosynthetic photon flux density.
