[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6h,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.
