【摘要】 立足北京市实际，以金叶榆（Ulmus pumila‘Jinye’）半球体造型半成品为供试种苗，以无容器常规地栽造型为对照（CK），共设6个容器化控根栽培处理，对比分析不同控根方法对苗木质量的影响，筛选出中等规格造型苗木培育方法，为批量生产特色苗木和创建精品园林提供可行方案。结果表明，处理Ⅴ细长型控根器D50 cm×H60 cm，实施部分控根与造型制作1.6年，能够培育出优质移栽容器造型苗，再应用到园林绿地中去，完好保持全冠，即时展现造型效果，出圃定植1年，其定植成活率、苗木地径及叶片盖度指标最大，造型成景美化效果最好。更多还原

【Abstract】 Based on the reality in Beijing City,semi-finished products of Ulmus pumila‘Jinye’in hemisphere modeling were selected as seedlings,with no container routinely plant model for control(CK),a total of 6 container control root cultivation processes were set up,and the effects of different controlling methods on the quality of the seedling root were compared and analyzed. Seedling cultivation method of medium specification modelling was screened to provide feasible solution for the mass production of characteristic nursery stock and the creation of exquisite gardens. The results showed that in the D50 cm × H60 cm slender shape root control device in processing Ⅴ,high-quality seedlings in transplanting containers could be cultivated by 1.6 a partial root control and modeling. Then the modeling seedlings with the full crown were applied to the gardens and greenbelts to show the modeling effect immediately. When planting for 1 a after out of nursery,the planting survival rate,seedling ground diameter and leaf coverage index were the largest and the landscape beautification effect in hemisphere modeling was the best.更多还原
