野生结缕草坪用性状的综合评价

Comprehensive evaluation on turf characteristics of Zoysia japonica

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。
