| 摘 要： | 通过对北京山区野生地被植物涝峪苔草Carex giraldiana对光照、温度、土壤、水分等生态因子适应性研究。结果表明:涝峪苔草能够在全光照及浓荫(郁闭度为0.8的林下)条件下都能够正常生长发育,具有较强的耐荫能力、抗旱性及节水性;在黄土中生长能忍受的土壤最低含水量为4.1%,在沙土中生长能忍受的最低土壤含水量为3.2%;能够在黄土、细沙土、建筑渣土中正常生长;适于作观赏性地被植物,不适于作运动性地被植物。涝峪苔草叶片寿命为18个月,绿期长。涝峪苔草能忍受-16.4℃的绝对低温和42.2℃的绝对高温,是北京地区城市立交桥下、建筑物背荫处、林下及护坡绿化的优良野生乡土地被植物。

| Abstract: | Ecological adaptability of wild Carex giraldiana as one of the ground cover plants in Beijing area was studied in this paper.Results showed that it could grow and develop normally under sunlight and dense shade(canopy density>0.8).Its shade tolerance,drought tolerance and water saving capacity was very high and could endure 4.1% moisture content in yellow soil,3.2% moisture content in sandy soil.However,this plant was suitable for lawn, not for sports turf.The leaves could grow 18 month with long green peri... |
