Abstract
The invention discloses a method of rapid generation-adding breeding of rice in the technical field of rice breeding, including soaking seeds of the rice, germination, seedlings cultivation, managing and regulating of the rice at the growth stage, and harvesting the rice. The managing and regulating the rice at the growth stage includes dynamic light quality and photoperiod control in vegetative growth period, heading period and pustulation period; growth period involves light environment regulation with the ratio of red light:blue light:white light of 0.8-1:0.8-1:1.0, photoperiod of 16-18 h; heading period involves light environment regulation with the ratio of red light:blue light:white light of 1-2:0.5-1:1, photoperiod of 12-13.5 h; and pustulation period includes light environment regulation with the ratio of red light:blue light:white light of 1-2:1:1, photoperiod of 16-18 h.
