以湖南省普遍用于城市绿化的杂交狗牙根天堂草328(Cynodon dactylon×C.transadlensis Tifdwarf328’)为对照,对野生结缕草(Zoysia japonica)的坪用性状进行综合评分,以确定其应用范围。结果表明:野生结缕草草坪优于对应类型的杂交狗牙根草坪。但由于其存在种子收集困难,生长速度慢等缺点,不宜用于水土保持草坪,建议在观赏草坪、游憩草坪和运动场草坪中推广应用;杂交狗牙根适用于水土保持草坪、游憩草坪和运动场草坪,但由于其密度小、绿色期短等缺点,不是观赏草坪的理想草种。
The cross-breeding traits of wild Zoysia japonica were scored with Cynodon dactylon × C. transadlensis Tifdwarf328 ’, which is commonly used for urban greening in Hunan Province, to determine its application range . The results showed that the wild zoysiagrass was superior to the corresponding hybrid bermudagrass lawns. However, it is not suitable for water and soil conservation because of its shortcomings such as difficulty in collecting seeds and slow growth rate. It is suggested that it should be widely applied in ornamental lawn, recreation lawn and sports field lawn. Hybrid bermudagrass is suitable for soil and water conservation lawn, recreational lawn and sports field lawn, However, due to its low density, short green period and other shortcomings, is not the ideal grass to watch the lawn.
