夏季是养兰的最忙季节,也非常关键。笔者对此有如下体会: 一、遮光兰花为半荫性花卉,必须避开强光与高温。遮荫蔽光的办法有多种,如:可根据日光呈前倾弧形走向的原理,利用南向高大建筑物的背面作为养兰场地,这样既能避开中午前后的强热光照,又可接受朝阳与夕晖;也可贴近高大乔木的北半部栽兰养蕙,因为稀疏的树叶白天能为兰花遮光吸热,夜间对兰花吸收露水又无多大影响;当然最好还是设置荫棚,此法虽费工费时,又需一定的投资,但效果甚好,可根据阳光的强弱、天气的阴晴、季节的变更、各兰种的采光要求加以调整,是行之有效的最佳遮光 Summer is the busiest season for cultivating orchids and is also very crucial. I have the following experience: First, shading orchids semi-shade flowers, you must avoid glare and heat. There are many ways to shade and shade. For example, according to the principle that the sunlight is curved in a forward arc direction, the back of the south tall building is used as the site for the cultivation of yinlan so as to avoid the intense heat before and after noon, Accept the sun and Xi Xi; can also be close to the northern half of the tall trees planted Yang Hui, because the sparse leaves during the day for orchid sunshade, night orchid to absorb dew and no major impact; of course, the best is to set the shade shed, Although this method costs time and costs, but also a certain amount of investment, but the effect is very good, according to the strength of the sun, the weather sunny, seasonal changes, the various species of lighting requirements to be adjusted, is the best Shading
