摘　　要：通过比较分析新引进铁皮石斛的农艺性状和石斛总多糖含量的变化,为吉安引进优良铁皮石斛品种“雁吹雪3号”提供理论依据。研究结果表明:3月至5月期间为铁皮石斛生长旺盛时期,“雁吹雪3号”的株高、茎粗、顶叶长和宽等农艺性状,以及干鲜重、石斛总多糖含量均高于吉安主栽品种仙斛1号,采收最佳时间为第3年的5月开花之前。雁吹雪3号三年生干燥茎的石斛总多糖含量平均为31.74%,符合药典标准,适于在吉安引进推广。The introduction feasibility of“No.3 Yan cui-xue”,a variety of Dendrobium offcinale,is investigated by comparing the agronomic characteristics and polysaccharides content of the local variety“No.1 Xian hu”and those of“No.3 Yan cui-xue”.The results show that D.offcinale grows fast from March to May.The height,stem diameter,leaf area and polysaccharides of“No.3 Yan cui-xue”are all higher than“No.1 Xian hu”.Therefore,it is suitable to introduce“No.3 Yan cui-xue”in Ji’an.Harvesting time of“No.3 Yan cui-xue”is before blossom in May of the third growth year,and the polysaccharides content of its dry stem is 31.74%,which is conformed with the standard in Pharmacopeia of P.R.Chinese.
