五、喜干而畏煤兰花为肉质粗根,根上有个假鳞茎(球状茎),它们都储存育相当的营养物质和水分以供应叶片的蒸发.一般可维持半个月,短时间没浇水,并不会因失去水分给养而萎蔫,可以说兰花有相当的耐旱性。所以,兰土宜偏干,兰叶不滞留水滴。但过长时间没浇水,兰土长时间干白,空气湿度又低,当然会因过分干燥,得不到应有的补给而枯萎。兰花原生长于山野林间,自然荫蔽好,空气湿度大,长得楚楚动人。人工栽培常因空气湿度低,导致叶片先端焦黑。因而兰花架下的场地,应设置浅水槽盛水或铺上粗河沙或海绵并淋透水,以增加兰场空气湿度。六、喜土而畏厚兰花原生于山野林间的土表上,其球茎常裸露或半截在土里,半截在上面之上,根系少深扎,多在土表层四面开拔。这就形成了喜土而畏厚的特性。这里的厚,是指忌深植,即其球茎应露出土表一半许。另一方面,盆底部应有易透气渗水的泡沫塑科块或碎砖瓦块等作为垫层,这样透气渗水性能才会良好,才有利于兰株的生长发育。 Five, hi dry and fear of coal Orchids for the fleshy roots, there is a fake bulb root (bulbous stems), they are stored and fertilize considerable nutrients and moisture to supply the leaves of the evaporation can generally maintain two weeks, a short time without pouring Water is not wilted by the loss of water supplies. It can be said that orchids have considerable drought tolerance. Therefore, blue soil should be dry, blue leaves do not stagnant water droplets. However, no water for a long time, blue soil dry white for a long time, the air humidity is low, of course, due to excessive dry, not get the necessary supplies and withered. Orchid original growth in the mountain forest, the natural shade, air humidity, lovely. Artificial cultivation often due to low air humidity, leading to the tip of the leaf coke. Therefore, under the orchid shelf, the shallow water tank should be set or covered with coarse sand or sponge and seep through the water to increase the air humidity of the blue field. Sixth, hi soil and fear Hou Hou Lan was born in the mountain forest between the earth’s surface, the bulbs often exposed or half in the soil, half above the above, less deep roots tie, and more in all directions on the surface of the earth. This formed a hi terribly fear of the characteristics. Thick here, refers to avoid deep planting, that is, its bulbs should be exposed half of Xu table. On the other hand, the bottom of the basin should be prone to breathable foam plastic blocks or broken brick blocks as a cushion, so breathable water seepage performance will be good, it will help the growth and development of blue plants.
