Claim 5:
6. A spectrum ratio operating method for a plant lamp device, and the spectrum ratio operating method comprising:
controlling a controller to turn on a first light bead group of a light bar, to make the first bead group irradiate growth spectrum on seedling plants and adult plants, wherein a red-to-blue light irradiance ratio of the first bead group is 3.9:1; and
controlling the controller to turn on the first light bead group and a second light bead group which are disposed in the light bar in interlaced arrangement, and the growth spectrum of the first bead group is different from growth spectrum of the second bead group and applied to irradiate plants in flowering stage, the red-to-blue-light irradiance ratio of the first bead group and the second bead group on an irradiated area is 7:1.
