摘　　要：以大兴狼垡城市森林公园建设树木移植为分析对象,选择银杏、柳树、榆树3个树共计360株,分别配置不同浓度的生长促进剂与土壤增氧剂,并联合灌根移植树木观察了其应用效果。在考虑土壤特点的基础上配置药液,移植树木的生长数据通过直观观测、死亡率、新根数、新根平均长度、新根平均直径几个角度对移植树木进行了评价。结果表明:(1)采用低浓度的药液对树木移植应用效果欠佳,死亡率为6.67%;(2)高浓度药液下移植树木的新根数量约为不施加药液移植树木的2.5倍,其新根长度、新根直径也明显增大。低浓度药液具有显著的经济性,特别是在狼垡城市森林公园的大面积使用中尤为显著。研究结果对大兴区乃至北京郊区树木移植提供一定的理论依据,具有良好的示范、带动和指导意义。This paper takes the tree transplantation of the construction of Daxing Langfa Urban Forest Park as the analysis object. A total of 360 trees ginkgo, willow, and elm tree are selected. Different concentrations of growth promoter and soil oxygenator were allocated respectively, and the trees were transplanted by combined root irrigation to observe the application effect. On the basis of considering the soil characteristics, the medicinal solution is prepared, and the growth data of transplanted trees are evaluated through visual observation, mortality, new roots, average length of new roots, and average diameter of new roots. The results showed that:(1) The effect of low concentration liquid medicine on tree transplantation was not good, and the mortality was 6.67%;(2) The number of new roots of trees transplanted under high concentration of liquid medicine was about 2.5 times that of trees transplanted without liquid medicine, and the length and diameter of new roots also increased significantly. The low concentration liquid medicine has significant economic benefits, especially in the large-scale use of Langfa Urban Forest Park. The research results provide a theoretical basis for tree transplantation in Daxing District and even in the suburbs of Beijing with good demonstration, driving and guiding significance.
