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.

Method of rapid generation-adding breeding of rice

A method for improving optical performance of an LED light source, a light conversion filter obtained by using the method, and the corresponding LED light source. In the method, an LED chip is packaged by using a light wavelength conversion component, and the light wavelength conversion component is at least provided with two types of light conversion filters with light excitation performance. With the excitation of light rays that are sent by the LED chip and have wavelengths in an ascending order, sent light rays show an opposite change tendency in light intensities of light rays after the light rays are converted by the two types of light conversion filters. The method can reduce the discrete degree of chroma distribution of light transmitted by the LED light source, and improve the defect-free rate of the LED light source.
