Control method for one-lamp-multi-functional LED plant light supplementary lamp

The invention relates to the technical field of illuminating light sources, in particular to a control method for a one-lamp-multi-functional LED plant light supplementary lamp. The control method ischaracterized in that LED chips of the light supplementary lamp are integrated on one lamp holder at an array manner; the LED chips comprise a group of red chips of which the wave length is 450-470 nm, a group of golden chips of which the wave length is 580-595 nm and a group of green chips of which the wave length is 625-640 nm; each group of LED chips is driven by a driving circuit; at a root and shoot growing period, the first group is lighted, and red light o f450-470 nm is emitted; at a stem and leaf growing period, the second group is lighted, and golden light of 580-595 nm is emitted; at a flowering period, the third group is lighted, and green light of 625-640 nm is emitted; at a color and mouthfeel maturing period, the three groups are all lighted, light with the wave length of 650-660 nm is emitted; and
