黄连(coptis chinensis Franch)为毛茛科多年生常绿草本药用植物。由于原生长在高山峡谷森林之中,形成了喜荫凉渐湿、怕干旱积水,喜疏光、怕曝晒的遗传特性。为适应这一特点,人们在生产上都采用人工搭棚来为黄连遮荫,使其在适度的光照条件下进行正常生长以获得较好的产量。搭木架棚,每亩需木材3～4立方米,耗材惊人,对林业生产不利,长此下去,森林破坏严重,发展黄连也将走投无路。为解 Coptis chinensis Franch is a perennial evergreen herbaceous medicinal plant of Ranunculaceae. As the original growth in the alpine forest in the forest, the formation of hi shade getting wet, afraid of drought water, hi sparse, afraid of exposure to the genetic characteristics. In order to adapt to this feature, people use artificial scaffolding to shade Coptis to make them grow normally under moderate light conditions to obtain better yields. Take wooden shelves, wood per mu need 3 to 4 cubic meters, consumables amazing, unfavorable to the forestry production, the long run, the forest damage is serious, the development of Coptis will be desperate.
