摘　　要：黎蒴是广东省重要的乡土阔叶树种之一,也是广东省次生常绿阔叶林主要组成树种之一。梅州市林业科学研究所采用不同的插床基质和生根促进剂,采用不同方法处理穗条,在不同季节进行反复比较试验,结果表明:黎蒴扦插基质宜选用黄心土与河砂(按9∶1比例);扦插生产宜在秋季开展;选用半木质化穗条,采用激素处理后,能获得较高的成活率。黎蒴无性繁殖技术可应用于生产。Castanopsis fissa is an important native broad-leaved species and secondary evergreen broad-leaved forest species in Guangdong province. Providing a variety of culture media, the paper studied the rooting accelerator, cutting processing time and cutting comparison of the cutting, the results showed that ： the ideal substrate cutting media was yellow subsoil and river sand （at 9： 1 ratio） ; cutting production in the autumn was the best; the survival rate was increased by using the semi-lignification cutting and growth hormone. Cctstanopsisfissa asexual reproduction technology can be applied to production.
