In this study, the effects of red and blue Light Emitting Diodes (LED) light on flowering and fruiting in the facility cultivation of tomato plants were investigated, tomato plants were subjected to 4 light treatments, dysprosium lamp (as the control, CK) and another three LEDs light with different ratios of red and blue light (RB1, RB2, RB3, R, B). The results showed that under the light with the ratio of red and blue 1:1, the time of first flower and first fruit appeared significantly earlier. The pollen viability and the content of soluble solids sucrose were the highest, and the ratio of sugar to acid is high, which made tomatoes taste great. This study is expected to provide theoretical basis for the high-quality cultivation of tomato seedlings.
