一、阳台栽兰花的条件选择方向必须向东南背西北。原因是东南方向的日照光好,利于兰花的生长发育,这是自然规律。上过山采寻兰花的人都知道,兰花多生长在东南方向的山坡上,在西北方向的山坡上很难采寻到兰花,就是有也很少,长势很弱。但在西北方向的阳台栽兰也未尝不可,但难度要大得多。首先要遮好西晒强光,其次要避挡西北风吹。兰花是阴生植物,在东南方向的阳台也要适当遮荫,防止曝晒。二、品种选择细叶兰比阔叶兰好栽培。细叶兰的蒸腾量要比阔叶兰小,细叶兰对光照防风的要求没有阔叶兰严格。特别是蕙兰和建兰好栽,寒兰对光照和防风要求较严格,一定要遮好荫,挡好风。否则难种活。 First, the balcony planted orchid conditions to choose the direction must be southeast to northwest. The reason is that the sunshine in the southeast is good and conducive to the growth and development of orchids, which is a natural law. People who look for orchids in the mountains know that orchids grow more on southeast slopes. It is hard to find orchids on the northwest slopes. But in the northwest of the balcony planted blue is not a bad idea, but the difficulty is much greater. First of all cover the West sun glare, followed by Northwest wind to avoid. Orchid is a shade plant, in the southeast of the balcony should also be appropriate shade to prevent exposure. Second, the choice of varieties Fine leafy leaf better than broadleaf cultivation. Slender leaf transpiration rate than the broadleaf small, fine leafy light on the wind without the requirements of broadleaf strict. In particular, Cymbidium and good planted blue, cold blue light and wind more stringent requirements, we must shade shade, block the good wind. Otherwise difficult to live.
