Air layering was one of important tree propagation techniques, the seedlings propagated by ase of this technique could preserve excellent merits of the stock plants,with early blossoming and fruiting. But there were some shortcomings of low breeding coefficient and manual work efficiency,which led to a lower utilization of air layering.Analysis was made of the influence factors of layer rooting rate, including layering period, materials, medium, procedure, hormone treatments, containers and so on. And it was discussed that the influencing factors of survival rate of seedlings, such as cultivation and management, technical issues of layering. In the future development of air layering, it should be emphasized that the rooting rate of air layering and the survival rate of seedlings must be improved as much as possible.
