兰花是我国名贵花卉之一,素有“香祖”之誉。我国兰花约有一万个品种,其中栽培较广泛的有惠兰、春兰、建兰、多花兰、墨兰、寒兰等。许多人认为兰花难养,其实不然。兰花原产于山谷林下,与草木为伍,并非秉性娇弱,只要掌握其生态习性,努力创造适合其生长的环境条件,是完全可以养好的。兰花喜温暖而湿润的气候,喜阴湿,要求遮荫度为70～90%,忌高温、干燥和强光。一般春兰的生长适温为18-24℃。兰花宜采用疏松肥沃微酸性腐叶土,以PH值5.5-6.5为好。由于兰花叶面积小,叶革质,具肉质根,所以土壤积水易烂根,故有“干兰湿菊”之说。 Orchid is one of China’s rare flowers, known as “Hong Zu ” reputation.
