利用不同树种木头附生栽培铁皮石斛研究初探

Preliminary study on epiphytic cultivation of dendrobium officinale kimura et migo with wood of different tree species in Guangxi

【目的】研究利用不同树种种植铁皮石斛的可行性,为研究适宜广西种植名贵药材铁皮石斛提供参考。【方法】选用广西本地常见的资源较丰富的五种树种,龙眼木、荔枝木、三角梅、芒果木、苦楝木进行铁皮石斛附生种植比较试验,观察不同树种对铁皮石斛苗移栽成活率、萌芽数、株高、茎粗和根数的影响。【结果】铁皮石斛选择不同附生树种木头栽种的成活率大小为:龙眼木>芒果木>苦楝木>荔枝木和三角梅。龙眼木上的铁皮石斛生长120天后萌芽数达4. 2个、株高4. 35cm、茎粗3. 54mm和根数24. 6条。【结论】龙眼木栽培铁皮石斛长势更好,建议铁皮石斛选择附主木头时,选与龙眼木相类似的木头。

【Objective】To study the feasibility of planting dendrobium officinale kimura et migo with different tree species by epiphytic method,using domesticated seedlings of dendrobium officinale kimura et migo as seedlings and moss as supplementary materials.【Method】Five tree species with abundant local resources,longan,litchi,triangular plum,mango and azedarach,were selected for the comparative experiment of dendrobium officinale kimura et migo epiphytic planting.The effects of different tree species on the survival rate,germination number,plant height,stem diameter and root number of dendrobium officinale kimura et migo seedlings were observed.【Result】The survival rate of dendrobium officinale kimura et migo wood planted with different epiphytic species was longan>mango>melia azedarach>litchi and triangle plum.After 120 days of growth,dendrobium officinale kimura et migo on longan trees had 4.2 germination,4.35cm plant height,3.54 mm stem diameter and 24.6 roots.【Conclusion】The dendrobium officinale kimura et migo grows better under longan cultivation.It may be that dendrobium officinale kimura et migo is an aerial rooting plant,while longan tree has rough bark,longitudinal fissure ditches and moss.It has better ventilation,permeability and water retention.Such an environment is conducive to the survival of dendrobium officinale kimura et migo and ensures the survival rate of dendrobium officinale kimura et migo.The experiment opens up a new way for the study of dendrobium officinale kimura et migo which is suitable for planting valuable medicinal materials in Guangxi.
