摘要
[目的]掌握影响大树移植成败的因素。[方法]通过选择不同的树体、不同移植季节及不同促活措施等进行对比试验。[结果]移植选择易成活、寿命长的浅根系、实生、再生能力强的乡土树木为佳;选择最佳移植季节、采用先进的促活技术都能有效提高大树移植成活率。[结论]大树移植规格适中的中龄乡土树种成活率高;在延安地区,早春和暮秋进行大树移植最好;生根粉、保水剂、输液等先进的促活技术能有效提高移植成活率。
[Objective]The aim was to study factors which influenced success of tree transplanting.[Method]The comparison test was conducted, by choosing different trees, different migration seasons and different measures to promote live. [Result] Choosing easy to survive, long-lived shallow root, seedling regeneration ability of native trees was better; Choosing the best migration season and advanced technology for promoting live could greatly improve the survival rate of living.[Conclusion ]The survival rate of specifications moderate middle-age native trees in tree transplanting was high. Tree transplanting in early spring and late autumn was the best in Yan'an Area. ABT, insurance agent, infusion and other advanced techniques could greatly improve the survival rate of transplant.
