摘　　要：为筛选铁皮石斛组培苗驯化移栽的适宜培养基质,采用9种不同基质组合进行移栽试验,以筛选出适宜的栽培基质。结果表明:不同基质组合对铁皮石斛组培苗驯化移栽成活率、发病率和生长量的影响差异显著。以处理5(碎石∶水苔=1∶2)成活率最高,极显著高于其他处理,并且发病率最低,极显著低于其他处理,成活率和发病率分别为96.92%和1.1%。处理5的铁皮石斛单丛鲜重、株高、茎粗、萌芽数、总根数、最长根系长度等6个生长量指标也显著高于其他处理,分别比对照(细刨木片5+锯末1)增长40.74%、48.43%、7.69%、5.86%、11.70%、3.97%,是铁皮石斛组培苗驯化移栽的最佳基质。In order to select the suitable culture substrate for the domestication and transplanting of Dendrobium officinale tissue cultured seedlings,9 different substrate combinations were used to carry out the transplanting test,in order to screen out the suitable culture substrate.The results showed that the effects of different matrix combinations on the survival rate,incidence and growth of tissue cultured seedlings of Dendrobium officinale were significantly different.The survival rate of treatment 5(crushed stone∶mosses=1∶2)was the highest,which was significantly higher than that of other treatment groups,and the incidence was the lowest,which was significantly lower than that of other treatment.The survival rate and incidence were 96.92%and 1.1%,respectively.In addition,the six growth indexes of Dendrobium officinale in the treatment 5,including the fresh weight,plant height,stem thick,budding number,total root number,and the longest root length were also significantly higher than those in the other treatment,which respectively increased by 40.74%,48.43%,7.69%,5.86%,11.70%and 3.97%compared with the control(fine shaving wood chips 5+sawdust 1).It was the best substrate for the domestication and transplanting of tissue cultured seedlings of Dendrobium officinale.
