西南区野生马蹄金坪用景观价值研究

Study on Turf Landscape Quality of Native Dichondra repens in the Southwest of China

以23份分别采自四川、云南、贵州的野生马蹄金为材料,美国引进品种普通马蹄金为对照,参考禾本科草坪草的五级9分制对其进行坪用景观价值系统评价,测定其叶面积、均一性、叶色、绿色期、草层高度、成坪速度、叶平展度和绒毛等指标。结果表明:23份野生马蹄金根据其评价结果可聚为四类,其中GD200503、SD200513、GD200502景观价值得分较高。

The Dichondra repens imported from the U S was used as CK, through tested 23 wild samples of Dichondra repens collected from different areas in Siehuan, Guizhou and Yunnan province, assessing their turf landscape quality reference to five grade-nine points criterion of gramineous turfgrass, measuring leaf area, uniformity, leaf color, green period, turf height, establishing velocity, leaf flat degree and pubescence, which combined of weight coefficient of assessment index then showed that. 23 wild samples of D. repens can be clustered into four type according to the assessment results, there were some samples such as GD200503,SD200513,GD200502 had better turf landscape quality.
