摘要:
薹草属植物适合在城市园林中作为草坪地被植物应用,对恢复与改善生态环境具有重要作用。该文为了解北京市野生薹草资源,为薹草属植物新种质选育奠定基础,从2006年春季至2008年春季在北京20个区域进行薹草属植物资源调查、收集及园林应用评价。结果表明:薹草在北京地区分布较广,在山谷路旁、田边、山坡草地,疏林下、密林下和水边湿地不同生境类型均有分布,表现出耐荫、耐旱、耐瘠薄、耐水湿等适应性强的特点。共收集与保存了21种薹草属植物,并在田间小区观测其生长情况和物候期,通过抗逆性和质量性状综合评价,筛选出适于北京地区应用的3种草坪地被植物:青绿薹草、矮丛薹草、披针叶薹草。
Abstract:
Carex plant is excellent ground cover plants in city landscape,and plays an important role in the restoration and improvement of ecological environment,this paper in order to understand the wild Carex resources in Beijing,and lay the foundation for Carex plant germplasm breeding. From the spring of 2006 to 2008,we investigated the Carex resources at 20 sites in Beijing. The results showed that Carex was widely spread in various environment,including valley,roadside,field side,hillsides,under thin or thick forests and fringe wetland,which indicated that Carex had very high tolerance to shade,drought,leanness and waterlogging. In total 21 accessions of Carex were collected,and their growth and phenological periods were observed in field plots. According to comprehensive evaluation on their stress tolerance and qualitative traits,three species of Carex(C. leucochlora,C. humilis,C. lanceolata)suitable for grass plant in Beijing were selected.
