球根花卉有哪些?
球根花卉有哪些,根据球根花卉对温度的要求,可以将球根花卉分为春植球根和秋植球根。春植球根一般不抗寒,春天气温回升后,球根开始生长,夏季开花,冬季球根休眠。休眠期间应将球根从花盆中掘出,进行贮藏。常见的春植球根花卉有大丽花、美人蕉、唐菖蒲等。秋植球根一般都比较抗寒,秋季种植,春末夏初开花,夏季高温季节休眠。常见的秋植球根花卉有风信子、郁金香等。
根据其地下茎或根部的形态结构,大体上可分为5大类:
①鳞茎类。地下茎呈鳞片状,外被纸质外皮的叫做有皮鳞茎,如郁金香、水仙、朱顶红等;在鳞片的外面没有外皮包被的叫做无皮鳞茎,如百合等。
②球茎类。地下茎呈球形或扁球形,外被革质外皮,如唐菖蒲、香雪兰等。
③根茎类。地下茎肥大呈根状,上面有明显的节,新芽着生在分枝的顶端,如美人蕉、姜花、荷花、睡莲、玉簪等。
④块茎类。地下茎呈不规则的块状或条状,如马蹄莲、仙客来、大岩桐、晚香玉等。
⑤块根类。地下主根肥大呈块状,根系从块根的末端生出,如大丽花等,以上就是关于球根花卉有哪些的介绍。
