以9个菊花品种为试材，研究了不同遮光时长对菊花的生长期、现蕾期及开花期的影响。结果表明，与兰州地区7 — 8月自然光周期相比，短日照处理可促进菊花生长，提前现蕾和开花。综合比较，每天19:00时至翌日8:00时遮光，日遮光时长为13 h时能够促使菊花最快开花。

Nine Chrysanthemum cultivar were used as test materials， The effects of different shading duration on the growth stage， budding stage and flowering stage of Chrysanthemum were studied. The results indicated that compared with the natural light cycle of July and August in Lanzhou， short-day treatment can promote the growth of chrysanthemums，and lead to early budding and flowering. In a comprehensive comparison， the shading time from 19:00 to 8:00 of the next day and the shading time of 13 h can promote the fastest flowering of Chrysanthemum.
