为评价山西不同居群野生草地早熟禾(Poa pratensis L.)的坪用特性,采用完全随机区组设计,将山西20个不同居群野生草地早熟禾种质进行试验评价。通过对出苗期和成坪期的观察以及生长速度、再生速度、盖度、密度、质地、色泽、均一性、越冬率等指标的测定,对其坪用性状进行综合评价。结果表明:沁水Ⅱ和浑源Ⅱ居群的野生草地早熟禾出苗早、成坪速度快;沁水Ⅱ居群野生草地早熟禾的越冬率、密度和盖度高于对照和其他野生居群,沁水Ⅱ和浑源Ⅱ居群野生草地早熟禾的质地最佳.五台和沁水Ⅱ居群叶绿素含量显著高于其他居群(P<0.05)。沁水Ⅱ和浑源Ⅱ居群野生草地早熟禾的综合质量表现均衡且分值较高,适宜作为草坪草种植,是推广应用的最佳选择。
In order to assess the plowing characteristics of Poa pratensis L. in different populations in Shanxi Province, the germplasm of 20 wild populations of Poa pratensis L. from 20 different populations in Shanxi were evaluated by a completely randomized block design. Through the observation of the emergence and the growth phase, as well as the growth rate, regeneration rate, cover, density, texture, color, uniformity, overwintering rate and other indicators, The results showed that the early emergence and the fasting of wild meadow bluegrass in Qinshui Ⅱ and Hunyuan Ⅱ populations were faster than those in the control and other wild populations , Qinshui Ⅱ and Hunyuan Ⅱ were the best, and the content of chlorophyll in Wutai and Qinshui Ⅱ populations was significantly higher than other populations (P <0.05). The comprehensive quality of Kentucky bluegrass and Hunyuan Ⅱ wild grassland showed a balanced and high score, which was suitable for turfgrass planting as the best choice for popularization and application.
