摘      要：[Objective] Hard-branch cutting propagation technology of Fraxinus was studied under different environmental conditions. [Method] An orthogonal test was designed based on 1-year-old clones of F. pennsylvanica Marsh Lula 5. Under dif- ferent growth hormones, hormone concentrations and processing time, F. velutina Lula 2 and F. pennsy/vanica Marsh Yuanla 2 were treated by vacuum pump for 10 min, [Result] The decreasing order of cutting survival rates of Lula 5 under different etnvironments was small plastic flowerpot （94.4%）, nutrition cup （92.8%）, sand tray （56.1%）, and cuffings treated with 100 mg/L ABT, for 2 h, 200 mg/L ABT, for 4 h and 100 mg/L IBA for 6 h under large nutrition cup environment grew the best, showing a survival rate of 100%. Lula 2 and Yuanla 2 were subjected to vacuum pump treatment, the survival rate of cuttings under the sand tray environment was averagely 29%; and under the large plastic flowerpot environment, the survival rate of cuttings was averagaly 64.4%, and cuttings of Lula 2 treated with vacuum pump for 10 min in 200 mg/L ABTI showed a survival rate up to 95%, which was the highest among all treatments. It could be seen that whether cuttings were treated with vacuum pump, the survival rate of cuttings in sand tray was lower than those under other environments, while there was no big difference in survival rate of cut- tings between the nutrition cup and plastic flowerpot environments. [Conclusion] This study is of great significance to improvement of cutting propagation coefficient.
