在江苏南京地区引种大叶冬青绿化实践表明,大叶冬青幼龄耐荫性较强,苗期生长较慢,3a后生长加快。全光照圃地5a(2年苗栽植)仅高2.5m、D1.32.6cm;侧方遮荫对3~4a苗成活及生长有良好促进作用。将这一研究结果用于中山陵风景林杂阔林林相改造,下层种植,异龄复层混交。在郁闭度0.5~0.6的上层杂阔林环境条件下,成活保存生长较好,9a时能形成4.50~5.00m高的下层常绿景观;类似半照的林缘和行道绿化,有用于景观改良的潜力。在郁闭度0.70~0.80的杂阔林下,大叶冬青生长较差,不宜用于林相结构调整与森林景观改造。
The introduction of large-leaved Holly greening practice in Nanjing, Jiangsu Province showed that young Hollyhock had stronger shade-tolerance, slower growth at seedling stage and faster growth after 3a. The full-light field 5a (2-year-old seedlings planted) only 2.5m, D1.32.6cm; lateral shade 3 ~ 4a seedlings survival and growth have a good role in promoting. The results of this study were applied to the transformation of the forest landscapes with mixed forests in the middle of Sun Yat-sen, the planting of the lower layer and the mixture of heterogeneous layers. Under the condition of canopy density 0.5 ~ 0.6, the survival and growth of the upper layer was better, and the lower evergreen landscape of 4.50 ~ 5.00m could be formed at 9a. Similar to the semi- Improved potential. In the canopy density 0.70 ~ 0.80 under the shrubbery, Hollyhock growth is poor, not suitable for forest structure adjustment and forest landscape transformation.
