基本简介

冬红(学名: Holmskioldia sanguinea Retz. ),又名阳伞花、帽子花。为马鞭草科冬红属植物。从冬红这个名字就可以看出,它的花在冬季依然能开放出绚丽的红色。冬红在热带地区,常用于园林绿化,攀附在花架或墙壁上。亚热带、温带地区可作温室盆栽。

形态特征

常绿灌木,高3-7米;它的枝条伸长具蔓性,可修剪成灌木。叶对生,膜质,卵形或宽卵形,基部圆形或近平截,叶缘有锯齿,两面均有稀疏毛及腺点,但沿叶脉具毛较密;叶柄长1-2厘米,具毛及腺点,有沟槽。

花顶生,花萼伞形,花冠喇叭形,橙红色;花序梗具短腺毛及长单毛;花萼朱红色或橙红色,由基部向上扩张成一阔倒圆锥形的碟,直径可达2厘米,盛开时极为鲜艳夺目。花期为冬末春初。果实倒卵形,长约6毫米,4深裂,包藏于宿存、扩大的花萼内。

生长环境及分布

喜光,喜温热及排水良好的环境,原产喜马拉雅。现我国广东、广西、台湾等地有栽培,供观赏。冬红在热带地区,用于园林绿化,诱引于花架或墙壁上。亚热带、温带地区可作温室盆栽。

栽培技术

1、环境的选择

不同的地区养殖的位置也不一样,例如热带地区可以直接种在庭院或是园林中,既可观赏又可绿化,而温带地区及温度更低地区则需要在室内养殖。

2、温度的需求

它不怕夏季的高温,但无法抵抗冬季的低温,而最适宜它生长的气温则是23度至32度之间。

3、光照的需求

它的生长是离不开阳光的,甚至比任何植物都需要阳光,但若长期在阳光不充裕的环境下,就会停止生长,或是发生其它影响植物健康的问题。

4、水分的需求

冬季末便是它开花的时候,一直到次年初春结束,但在开花期就要减少浇水,这与其它植物花期正好相反,而且较干旱的环境会让它开出更好的花,所以开花前可以让土壤变得干旱些,但并不是一点水都不浇,只是不让它过于潮湿。

其它时间浇水可以根据土壤的状态进行,土壤上层出现偏干状,就可进行浇水。切忌不可使土壤长期过于潮湿,也不可出现积水。

5、肥料的需求

秋季是肥料施放的主要时期,尤其是在它的叶子凋落后,要施一次足肥;春季也要进行一次足肥施放,施肥过后要浇足水。

冬天养殖冬红的时候,只需要少量浇水,维持它正常生长即可,千万不能浇水过多,然后就是保证温度在20℃以上,不能出现温度过的的现象,还要给它充足的光照,保证花芽良好的生长,冬红
