铁皮石斛生根组培苗污染后的处理和利用

摘要

Dendrobium officinale is one of the precious chinese medicines. With the expansion of artifi-cial planting, seedlings were short. To reduce the production cost in the process of large scaled rearing and increase the utilization of polluted tissue-cultured plants, utilization of polluted tissue-cultured plants was studied. The results showed that the survival ratio and buds of polluted plants increased significantly, but morbidity dropped significantly when the plants were irrigated by oligosaccharins with 1 000 times, which mixed with sanmate with 1 500 times could promote the root growth, and make the plant stem strong and sprout more.%铁皮石斛( Dendrobium officinale)是名贵中药材，人工种植面积的扩大造成种苗短缺。为降低规模化育苗过程中的种苗生产成本，提高污染苗的利用率，对铁皮石斛组培污染苗的利用进行试验研究，结果表明，氨基寡糖素1000倍液可有效提高污染苗的移栽成活率，增加发芽率，减少发病率；结合1500倍多菌灵液双重使用，可促使根的生长发育，植株茎粗壮，萌芽多。
