摘要:
以番茄为试材，采用发光二极管（LED）作为光源，在260、200、150 μmol?m-2?s-1光强下，研究红蓝混合光（R/B=5∶5、6∶4、7∶3）对番茄幼苗生长的影响。结果表明：在以红蓝光混合的LED灯作为光源时，增加蓝光的比例，可抑制番茄幼苗徒长；综合各性状表现，在光强200~260 μmol?m-2?s-1、14 h?d-1光周期下，温度控制在25~20 ℃，红蓝光混合配比6∶4的LED光源有利于番茄幼苗生长。
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 ℃．
