摘　　要：【目的】研究具有较强生态适应性和较高实用价值的新型野生草坪草资源,为在关中平原及气候相似地区推广应用提供参考,同时为草坪草新品种选育提供思路。【方法】选择坪用性状表现较好的3种秦岭野生草莓即野生黄毛草莓(Fragaroa nilgrrensis Schlecht)、森林草莓(Fragaroa vesca L)及五叶草莓(Fragaroa pentaphylla Lonzink)进行坪用性栽培试验,观察、测定各项坪用性指标,参考国家标准分析叶片叶绿素及氮素含量、坪用性状、成坪草皮厚度和适应性,综合评价坪用价值。【结果】3种秦岭野生草莓在关中平原地区均能形成生长良好的观赏草坪。其中,黄毛草莓的盖度和均一性最好,其形成的单种草坪草皮厚度优于其他2种,混种草坪成坪草皮厚度优于单种;五叶草莓绿期最长(282 d),森林草莓次之(278 d),二者均显著优于黄毛草莓(262 d);草坪质量综合评价结果为黄毛草莓>五叶草莓>森林草莓。【结论】3种野生草莓均具有良好的坪用价值,其中以黄毛草莓综合评价结果最优,可作为新的坪用观赏草坪草在关中平原及生态条件相似地区栽培应用。【Objective】The new wild turf grass resources with the stronger biological adaptability and higher practical value are studied to provide a reference for their popularization and application in Guanzhong Plain and climatic similarity areas and provide an idea for breeding of new turf grass varieties.【Method】The turf value of Fragaroa nilgrrensis, F. vesca and F. pentaphylla with good turf traits is comprehensively evaluated by analyzing the leaf chlorophyll and nitrogen content, turf traits, turf thickness and adaptability according to the national standard.【Result】Fragaroa nilgrrensis, Fragaroa vesca and Fragaroa pentaphylla all can form the well-grown ornamental lawn in Guanzhong Plain. The coverage and uniformity of F. nilgrrensis is the best among three wild strawberry varieties. The turf thickness only formed from F. nilgrrensis is superior to F. vesca and F. pentaphylla, and the mixed turf thickness formed from F. nilgrrensis, F. vesca and F. pentaphylla is higher than that of the single turf grass. The green period of F. pentaphylla is the longest(282 d), followed by F. vesca(278 d) and F. nilgrrensis(262 d). The comprehensive turf quality of three wild strawberry varieties is F. nilgrrensis > F. pentaphylla > F. vesca.【Conclusion】Three wild strawberry varieties all have the good turf value. F. nilgrrensis with the best comprehensive turf value should be cultivated as a new ornamental turf grass in Guanzhong Plain and similar ecological areas.
