摘　　要：[目的]提高油茶扦插成活率,促进根系生长。[方法]该试验设8个处理和1个对照,各重复3次。研究不同处理对油茶插株成活率和生长的影响。[结果]通过激素处理的插根平均成活率在87.8%～100%,而对照的平均成活率仅67.9%,激素处理的平均成活率均显著高于对照;成活率最高的是强力生根粉500 mg/L、处理6 h,其成活率达到100%,显著高于对照和其他7个处理;从根系的数量分析看:以根太阳生根粉17.5倍液、国光萘乙酸1 000 mg/L、国光生根萘乙酸1 000 mg/L为优,3个处理的11条根以上苗木数量占总苗木数量分别为47.2%、33.0%、27.7%,5～10条根的苗木数量占总苗木数量分别为24.2%、21.0%、25.1%,其中以根太阳生根粉17.5倍液、处理12 s的最优,发根数量在5条以上的苗木数量占总苗木数量的平均值达71.4%;对照的发根数量在5条以上的苗木数量占总苗木数量的平均值仅为21.5%。[结论]油茶扦插繁殖技术成本低、效益高、成苗快,该试验可为大规模培育优质壮苗提供依据。[Objective]In order to improve the survival rate of Camellia cuttings and promote root growth.[Method]This test has 8 treatments with a comparison,repeat 3 times.[Result]The survival rates of treatments were from 87.8% to 100%,while the survival rate of water（the control） was only 67.9%,the survival rates of treatments were higher than the control.The survival rate of Qiang Li rooting powder with 500 mg/L was the highest,up to 100%,while the average survival rate of controls was only 67.9%.From the analysis on number of root,Gen Taiyang rooting powder with 17.5 times,Guoguang naphthalene acid 1 000 mg/L,Guoguang root naphthalene acid 1 000 mg/L for optimal.The three processing have over 11 roots of seedlings＇ number was 47.2%,33.0% and 27.7% respectively,have 5-10 roots of seedlings＇ number was 24.2%,21.0% and 25.1% respectively.With the Gen Taiyang rooting powder 17.5 times liquid,deal with 12 s optimal,have above 5 roots of the number was 71.4%;while in the controls,above 5 roots of the number was 21.5%.[Conclusion]The propagation technology of Camellia cutting were low-cost,high efficiency,fast-growing.This test can provide a basis for cultivating large scale and high quality seedling.
