摘　　要：以40年生高州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、ABT6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、插穗留芽数量和留叶量对成活率的影响较大,均达到极显著水平;4个因素对抽梢率的影响均达到极显著水平。高州油茶扦插育苗的最佳组合为:扦插基质选用黄心土,500 mg/L ABT6速蘸10 s,插穗选择1个成熟芽并保留2片全叶。Taking the mid and upper sections of about 40 years old ComeUia gauchowensis Chang semi-lignified branches as the cuttings, the cutting orthogonal experiments of cutting medium, ABT6 levels, the number of buds and the remained leaves 4 factors and 3 levels were carried out. The results showed that： cutting medium, the number of buds and the remained leaves extremely affected survival rate, 4 factors impact were extremely significant differences on the cutting sprout rate, and significant difference. The best treatment of C. gauchowensis Chang cutting seedling was： yellow soil cutting medium, ABT6 level was 500 mg/L and quick dip in 10 s, the cuttings selected 1 mature bud and kept 2 whole leaves.
