The invention discloses a self-adaptive light supplementing system and method for a plant factory. The distance between a light supplementing lamp 1 and plants 12 planted on a culture bed 10 is measured through distance measuring sensors 11, and a stepping motor 4 is driven to operate so as to drive a winding shaft 3 to rotate, so that the light supplementing lamp 1 is driven by steel wires 6 winding round winders 2 to rise or fall; and meanwhile, the light supplementing system can measure and calculate the illumination intensity of a plant canopy through an illumination intensity sensor 13, and then the illumination intensity of the light supplementing lamp 1 is adjusted to be adapted to light intensity requirements of different crops. The method is simple and practical, and the illumination intensity of the light supplementing lamp 1 and the distance between the light supplementing lamp 1 and the plants 12 can be adjusted, so that only set values of system software are required to be changed, and then cultu
