摘要
乡土地被植物因其适应性强、病虫害少及养护成本低等优势在城市园林绿化应用中逐渐受到人们的关注。本研究选择深圳地区常见的3种乡土植物链荚豆(Alysicarpus vaginalis)、丁癸草(Zornia gibbosa)和酢浆草(Oxalis corniculata),通过测定其株高、质地、密度、绿度、均一性、绿期、盖度、建植速率以及耐践踏性共9项指标,并按照"景观-性能-应用适合度"综合评价指标体系进行评价。结果表明,链荚豆耐践踏性较强、草坪强度高、建植速率较快,可作为游憩草坪以及保土草坪替代品种推广;丁癸草耐践踏性强、草坪强度高,可作为游憩草坪替代品种进行推广;酢浆草则因为叶形美、密度高、生长均匀,适宜作为观赏草坪替代品种进行推广。坪用价值综合评分以链荚豆在3种植物中最高,为14.550分;丁癸草次之(13.850);酢浆草最低(12.650)。3种乡土植物均具有较好的园林草坪应用前景,为深圳市及我国南方地区绿化工作提供了草坪草种新选择。
Indigenous plants are gradually attracting increasingly more attention for application in urban landscaping,because of their strong adaptability,low susceptibility to diseases and damage by insect pests,and low maintenance cost.In this study,Alysicarpus vaginalis,Zornia gibbosa,and Oxalis corniculate-three indigenous plants in Shenzhen area-were chosen,and their height,leaf width,leaf density,leaf shape uniformity,leaf color,greenness duration,coverage,growth rate and resistance were estimated.The results were analyzed using the“application landscape-performance-fitness”comprehensive evaluation index system to evaluate the turf value of the three plants.The results show that A.vaginalis can be used as recreational turf and soil conservation turf because of its resistance to intense trampling,high strength,and fast growth.Z.gibbosa is similar to the former and suited for planting as recreational turf.O.corniculata was found to have characteristics of high density and uniform growth.Therefore,it can be used as ornamental turf.The turf value comprehensive score of A.vaginalis(14.55)was the highest among the three plants,with the values for Z.gibbosa and O.corniculata being 13.85 and 12.65,respectively.All the three plants have a good prospect for turf application and provide new choices of turf-grass for afforestation work in Shenzhen City and even in southern China.
