摘要: 针对高海拔地区西宁市耐践踏草坪草品种筛选问题,本研究以13个草地早熟禾(Poa pratensis L.)品种为试验材料,设置无践踏、轻度践踏、中度践踏3个处理,通过测定坪观质量、生长特性和运动质量等13项指标,利用灰色关联度分析法进行耐践踏性综合评价。结果表明:归一化植被指数(Normalized difference vegetation index,NDVI)、色泽和株高在轻度践踏下部分品种显著增加,在中度践踏下,显著降低,但‘赛威’和‘蓝魔’变化不显著。多数品种地上生物量在轻度践踏下均有提高,中度践踏下则下降,各品种地下生物量在践踏处理下均降低。‘蓝魔’‘飞达’和‘午夜’在中度践踏下能维持较高根系表面积与体积。此外,践踏显著提高土壤紧实度、表面硬度和球反弹率。运用灰色关联度分析法综合多指标评价显示,‘午夜’‘飞达’和‘蓝魔’表现最优,值得推荐 。该研究结果为高海拔地区城市绿地和运动场草坪的草种选择提供了依据,可根据践踏强度优化草种,提升经济效益。

Abstract: In order to screen trampling resistant turfgrass varieties at high altitudes in Xining City, 13 grassland varieties Poa pratensis L. were used as test materials, and three treatments were set up: no trampling, light trampling and moderate trampling, and 13 indexes such as pingguan quality, growth characteristics and exercise quality were measured, and the gray correlation analysis method was used to comprehensively evaluate trampling resistance. The results showed that the normalized difference vegetation index (NDVI), color and plant height of some cultivars increased significantly under light trampling and decreased significantly under moderate trampling, but ‘Selway’ and ‘Blue Devil’ had no significant changes. The aboveground biomass of most varieties increased under light trampling decreased under moderate trampling, but the belowground biomass all decreased under trampling. ‘Blue Devil’ ‘Feida’ and ‘Midnight’ maintained high root surface area and volume under moderate trampling. In addition, trampling significantly enhanced soil compaction, surface hardness and ball rebound. The comprehensive multi-index evaluation using the gray correlation analysis method showed that ‘Midnight’‘Feida’ and ‘Blue Devil’ performed the best and were worth recommending. The results of this study provided a basis for the selection of grass species for urban green space and sports field lawn in high-altitude areas, and might optimize grass species according to trampling intensity to improve economic benefits.
