南宁青秀山荫生植物普查及其耐荫性研究初探

摘要

In the afforestation of Qingxiu Mountain Scenic Spot ,each region of the scenic spot should be fully beautified and layers and colors of the landscape should be strengthened .Since the shade tolerance of plant varieties is different due to insufficient light in the forest ,there isn't a clear quantitative standard on how to suit forest canopy density as well as to meet the requirements of the landscape .As the choice of shade plants in the original production mainly relies on the experience in the production ,some plants can not adapt to can‐opy density in the small environment and fail to grow well and gradually die ,which finally causes repeated construction and unnecessary wasting of resources .This article has conducted a comprehensive study on the existing shade plants on Qingxiu Mountain ,and has concluded the present situation of growth of the shade plants after planting on Qingxiu Mountain .The article also has a preliminary understanding of the shade tol‐erance of the shade plants ,w hich has laid a foundation for further study .%指出了青秀山景区绿化中应充分美化景区的每一个区域，增加景观的层次和色彩。由于林下光线不足植物品种耐荫能力各不相同，如何配置既能适合林木郁闭度，又能满足景观的要求，没有一个比较明确的量化标准，原有生产中耐荫植物的选择种植中依靠生产中的经验判断，使一些植物对小环境郁闭度无法适用，出现生长不良、逐渐死亡等问题，造成了重复施工和不必要的资源浪费。对青秀山中现有的荫生植物进行了较全面调查研究，总结了青秀山荫生植物的种植后生长现状，对荫生植物的耐荫性进行了初步了解，为对荫生植物耐荫性的进一步研究奠定基础。
