不同基质对铁皮石斛组培苗移栽成活率的影响

Effects of Different Substrates on Transplanting Survival Rate of Tissue Culture Seedlings of Dendrobium officinale

以铁皮石斛组培苗为材料,用松树皮、椰糠、谷壳、腐殖土等4种栽培基质进行炼苗,考察其对铁皮石斛移栽成活率的影响。结果表明:处理(1)以松树皮作为栽培基质,铁皮石斛苗在萌芽数、株高方面表现良好,且该基质在市场上量大价低,可以作为铁皮石斛栽培基质大面积推广使用。

In this paper,tissue culture seedlings of Dendrobium officinale were used as materials and acclimatized at four substrates including pine bark,coconut bran,chaff and humus soil.Effects of different substrates on transplanting survival rates were studied.The results showed that tissue culture seedling had high bud germination number and plant height when pine bark was used as substrate.Due to its large stock and low price of pine bark,it could be widely extended to use as substrate of tissue culture seedlings of Dendrobium officinale.
