摘　　要：以30a生广宁红花油茶树中上部当年生半木质化枝条作为插穗,开展扦插基质、ABT-6浓度、插穗留芽数量和留叶量4个因素各3个水平的扦插正交试验。结果表明:扦插基质、芽的数量和留叶量对扦插成活率和生根率的影响较大,均存在显著差异;芽的数量对扦插抽梢率的影响具有显著差异,抽梢率最大为47.50%。广宁红花油茶扦插育苗的最佳组合为:50%黄心土+25%泥炭土+25%椰糠混合基质;500 mg/LABT-6速蘸10 s;插穗选择2个以上成熟芽并保留2片全叶。The cuttage of Camellia semiserrata were studied by taking lignified branches of about 30 years old C. semiserrata as the cuttings. The cutting medium, ABT-6 levels, the number of buds and the remained leaves 4 the mid and upper cutting orthogonal sections of semi - experiments under factors and 3 levels were carried out The results show that the cutting medium, the number of buds and remained leaves had great influence on the cut- ting survival rate and rooting rate, and there were significant differences. The sprouting rate of cuttings reached 47.50% and was influenced by the number of bud significantly. The best treatment for culture of C. semiserrata cutting seedling is mixing medium of 50% yellow soil ＋ 25% peat soil ＋ 25% coir dust, and the cuttings with 2 whole leaves and more than 2 mature buds should be dipped quickly in 500 mg/L ABT-6 for 10 s.
