摘　　要：指出了榧树是集药用、果用、油用、材用、观赏和环保等多种用途于一身的珍贵经济树种。为了解决云南榧树有性繁殖不能保持良种特性,而现有扦插技术生根困难的问题,首次提出了一种云南榧树扦插繁殖方法。该方法简单易行、成本低,能够实现云南榧树的有效快速无性繁殖。同时探讨了云南榧树在园林绿化中的应用现状和前景,认为云南榧树是一种优良的乡土造景和造林树种。Torreya is a kind of precious economic fruit tree species which has many usages, including the medicinal use, fruity use, oilseed use, timber use, ornamental value and environmental protection. As the sexual reproduction of T. yunnanensis cannot keep good characteristics and the existing cutting technology has rooting problems, the article first proposes a cutting propagation method. This method has the advantages of simple operation and low cost, which can realize the effective rapid asexual reproduction of T. yunnanensis. The article also discusses the current situation and future application of T. yunnanensis in landscaping, and theT. yunnanensis is regarded as an excellent species for vernacular landscape and afforestation.
