西藏野生波伐早熟禾坪用性状及应用

Turf characteristics of wild Poa poiphagorum and its application in Tibet

为了明确西藏野生波伐早熟禾(Poa poiphagorum)的使用性能,研究采用草坪坪用价值综合评价系统,在自然条件和人工栽培条件下对波伐早熟禾的坪用性状进行了研究。结果表明,草坪质地、株高、绿期、草坪强度和成坪速度等指标评分较好,色泽指标评分中等,而草坪植株密度、均一性和生物量3个指标评分较低,波伐早熟禾作为草坪植物使用,需通过加强栽培管理措施或者育种手段来解决这些问题;对波伐早熟禾使用性能的综合评定结果说明,相对于作为观赏型草坪(综合评定值为3.1),波伐早熟禾更适合作为保土型草坪来应用(综合评定值为3.6)。

The comprehensive evaluation system of turf quality was used to evaluate the turf characteristics of wild Poa poiphagorum under the natural and artificial environments for defining the usability of this turf grass. This study showed that the turf texture, height, persistence, intensity and speed of turf estab- lishment performed well, and the turf color was not bad, but the turf density, uniformity, biomass was poor. Optimal cultivation and management measures or breeding methods would benefit the application of wild P. poiphagorum. This study also suggested that the P. poiphagorum was better used to establish the conservation erosion than to establish the landscape turf.
