林木高空压条生根率影响因素分析

Analysis of Influencing Factors of the Rooting Rate by Air Layering

高空压条技术是保留母本的优良性状,提早开花结果的重要林木繁殖技术之一。但高空压条技术也存在苗木繁殖系数低,人工效率低的缺点而未得到广泛应用。文章从压条时期、材料、基质、压条方法、激素处理、容器等几个方面对影响压条生根率的因素进行了分析。探讨了离体栽培管护、压条技术问题等影响育苗成活率的因素进行了。在今后高空压条繁殖技术的发展中,应尽可能地提高压条生根率和育苗成活率。

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.
