Abstract：In oeder to analyze the LED light with different red and blue light ratio for plant growth, This paper have set four contorl groups, for which red light to blue light ratio are 4 to 1, 1 to 3, 1 to 4, 2, to, 1, as compared with normal group illuminated by white light. More than this, we also have ensured in case of the exactly same of light source, photoperiod and light intensity to look into the effect of light quality on the cotyledon, main leaf and plant height of romaine lettuce under the circumestances and the detected results were statistically analyzed. The results of this experiment reflect on that the most favorable photoperiod for romaine lettuce is that red light to blue light ratio is 4 to 1 . Through the adjusting to experimental results, this can be used in plant factory to increase production efficiency.
