圣诞红的养植

樊问

位置:
尽可能不要放在路灯或下,否则红色苞片会再团圆绿色。秋冬一般在全日、半日照的阳台生长良好,放在室内者则要有散射光为宜。

土壤:
以疏松富含有机质且排水良好的砂质壤土为佳。

水分:
秋冬季1-2天浇一次水即可,若遇下雨及 冷天气则供水,否则根系易腐烂。浇水时不要让水积存在苞片上,放在室内的盆花底下可加一水盘,以免水漏到地上,也可保持土壤的湿润。

日照:
圣诞红喜欢充足的光线,秋冬季可在全日照或半日照下生长良好,开花期可室内明亮处欣赏,若光线不足,圣诞红会开始黄化及落叶。

温度:
生长适温在15-25度,冬天不要低于10度,否则会有落叶发生,但它也不耐高温,因此并不适合南方夏季生长。

肥料:
应在培养土里混合基肥。圣诞红因生长快速,需肥较多,最好以少量多次法来补充磷钾肥,减少氮肥供应,以使开花顺利。

照顾:
一般来说,家庭园艺或公司布置使用的圣诞红多是花市,已经栽培成为4英寸、5英寸、6英寸的盆花成品,回家后可直接放在客厅靠窗的位置,或是有散射光的地方。小心枝条若有折伤会有魄乳汁流出,较易过敏的人不要用手碰触,最好带着手套较安全。
