美人蕉是美化庭园的常栽植物。点缀花坛中心,或作花篱也十分美观。现在华北一带的机关、工厂或公园里多以丛栽美化环境。繁殖常用分割根茎繁殖法。清明时节,将贮藏的根状茎取出,分割开,每块应具有二至三个芽,覆土约十厘米,穴内应用堆肥和草木灰作基肥;生长期还应常施追肥。经常保持土壤疏松和湿润。周围空气要流通,日光要充足。根据多年经验,根茎贮藏,既怕冻,又怕热,也忌潮湿。因此保管不当,根茎就会坏死,真可谓“红颜薄命”。所以,深秋经霜一至二次后,叶即有些枯萎,应将根茎掘出,略加晒干,并用干沙土或锯末把它埋藏好,放在5～10℃的室内。切忌随便取出检查,引起“伤风感冒”,招致死亡。
Canna is often planted landscaping plants. Dotted flowerbed center, or for hedging is also very beautiful. Now in the northern part of the organs, factories or parks in order to beautify the environment. Commonly used breeding propagation rhizome propagation method. During the Ching Ming Festival, the stored rhizomes are removed and cut apart.
