Abstract: In order to explore the effects of different light quality on the quality of eggplant seedling, Hangqie No. 1 was used as the test material, and natural light was used as the control to analyze the effects of two different proportions of laser combination light RB205 and RB155 on the growth of seedlings. The results showed that different proportions of red and blue light combination had different effects on the growth of eggplant seedling. Compared with CK, the effect of RB205 combination light on the growth of eggplant seedling was not significant. The combination of RB155 light can significantly promote the growth of the above-ground part of eggplant seedlings.
