Abstract:: Tomato was used as material,effects of different light intensity and different light qualities generated by LED on growth of tomato seedlings were studied．Light intensities of 260，200，150 μmol?m-2?s-1 were designed with the complex light of red and blue LED (R/B=5∶5，6∶4，7∶3)，compared to the treatment of white fluorescent light(CK)．The results showed that increasing of blue light could inhibit the seedling spindling in the complex light of red and blue LED．Comprehensived various characteristics，under the conditions of 200-260 μmol?m^-2?s^-1 light intensity and 14 h?d^-1 photoperiod，the treatment of R/B=6∶4 LED was suitable for the growth of tomato seedlings at 25-20 ℃．
