摘　　要：为科学指导园林绿化植物的选择和培育,定量分析金叶复叶槭与雪球海棠的生长特征差异,统计了两者在容器苗和标准育苗条件下的生长指标,通过设置对照组,详细观察了两种植物的株高、叶数、分枝数和生物量的增长情况。对两种植物各自的相对生长指标对比、两者之间的绝对生长指标对比。结果表明:在株高、叶数增长量、分枝数、生物量积累方面,金叶复叶槭的相对增长速度高于雪球海棠的相对增长速度;在观察期内,容器苗金叶复叶槭相对增高131.16%,容器苗雪球海棠相对增高85.5%;容器苗金叶复叶槭叶数增长平均量为171.7,容器苗雪球海棠叶数增长平均量为95.5;容器苗金叶复叶槭分枝数增长量为18.9,容器苗雪球海棠分枝数增长量为11.7;容器苗金叶复叶槭生物量积累增长量为403.6,容器苗雪球海棠生物量积累增长量为300。同时,两种植物的容器化组增长速度高于非容器化组增长速度;金叶复叶槭生长速度更快,更适合作为速生树种进行培育。This paper is to provide scientific guidance for the selection and cultivation of garden greening plants,and to quantitatively analyze the differences in growth characteristics between Acer negundo 'Aurea' and Malus 'Snowdrift'.Method:the growth indicators of both plants under container and standard seedling conditions are calculated.A control group is set up to observe the growth of plant height,leaf number,branch number and biomass.The relative growth indicators and absolute growth indicators of two plants are compared.Result:The comparative analysis results showed that in terms of plant height,leaf number growth,branch number,and biomass accumulation,the relative growth rate of Acer negundo 'Aurea' was higher than that of Malus 'Snowdrift';During the observation period,the container seedlings of Acer negundo 'Aurea' showed a relative increase of 131.16%,while the container seedlings of Malus 'Snowdrift' showed a relative increase of 85.5%;The average increase in the number of leaves of container seedlings of Acer negundo 'Aurea' is 171.7,and the average increase in the number of leaves of container seedlings of Malus 'Snowdrift' is 95.5;The increase in the number of branches in container seedlings of Acer negundo 'Aurea' is 18.9,and the increase in the number of branches in container seedlings of Malus 'Snowdrift' is 11.7;The growth rate of biomass accumulation in container seedlings of Acer negundo 'Aurea' is 403.6,and the growth rate of biomass accumulation in container seedlings of Malus 'Snowdrift' is 300.The growth rate of the containerized group of both plants is higher than that of the non-containerized group.Conclusion:The growth rate of Acer negundo 'Aurea' is faster,making it more suitable for cultivation as a fast-growing tree species.
