近年来,把观叶植物当作室内装饰来应用,已逐渐被越来越多的人们所接受。这是因为观叶植物株形优美,叶色绚丽,或者花叶俱佳,观赏时间长,不受季节限制,栽培容易。但在北方冬季温度偏低和空气干燥,宜选用哪些室内观叶植物,却是一个十分重要的问题。首先,大多数观叶植物原产于热带和亚热带地区,这些地区的年平均温度高,没有明显的季节变化,冬夏、昼夜温差小,所以栽培要求温度一般要达到15℃以上。而在北方的一些居室,冬季温度经常达不到15℃,甚至有时在10℃以下,观叶植物在这种条件下很容易遭受冻害,甚至死亡,比如,花叶万年青、白网纹莱、变叶木等均属此类。其次,需要空气湿度高的观叶植物所占的 In recent years, the application of foliage plants as interior decoration has gradually been accepted by more and more people. This is because foliage plant plants beautiful shape, leaf color gorgeous, or mosaic are good, watch a long time, not subject to seasonal restrictions, cultivation is easy. However, in the northern winter temperatures are low and dry air, which indoor foliage plants should be selected, but it is a very important issue. First of all, most of the foliage plants are native to the tropics and subtropics. The annual average temperature in these areas is high with no obvious seasonal changes. The temperature difference between winter and summer is small, so the cultivation temperature is generally above 15 ℃. In some northern rooms, winter temperatures often reach less than 15 ° C, sometimes even below 10 ° C. Under these conditions, foliage plants are vulnerable to frost damage and even death, for example, Cymbidium evergreen, Change leaves belong to this category. Second, foliage plants that require high air humidity are accounted for
