摘要
本文研究了冬季温室内不同光照强度对唐菖蒲花芽发育的影响。冬季温室内自然光照强度不够,唐菖蒲花芽大部或全部败育,开花株率和每穗开花率极低。全生育期采用高压钠灯(SON-T)补充12小时5000lx 光照,花芽发育较好,开花株率达85%以上,每穗开花率可达60%以上。唐菖蒲3叶或5叶期至开花期对光照强度很敏感,在此期间再开始补充12小时5000lx 的光照,同样可以降低花芽败育率,从而节约电能,降低生产成本。
In winter months,the scarcity of solar irradiance caused a serious flower-bud abortionin forcing of Gladiolus in greenhouses;12h.5 000lx supplementary light by 400Watt highpressure sodium lamps(SON-T)from 18∶00 to 6∶00 reduced blasting plants and producedmarketable cut-flowers of Gladiolus.The stage from the 3rd or 5th leaf to anthesis was themost sensitivc stage to light intensities.12h.5 000lx was supplied by SON-T when plant’s 3rdor 5th leaf was visible,and the results were almost the same as those with 12h.5 000lx sup-plementary light at all times.
