Abstract: In order to investigate the impact of traffic stress on the perennial ryegrass (Lolium perenne) in different brands of paved hybrid turfs,this study used two types of hybrid turfs as experimental materials and common bermudagrass(Cynodon dactylon)as a control. An 8-week traffic stress treatment was conducted using a trampler. The results showed that under prolonged trafficking,the color,total density,and coverage of the two hybrid turfs were superior to those of natural turf. Under trampling treatment,the biomass of hybrid turfs was higher than that of natural turf due to its protective effect due to the presence of artificial grass fibers. Compared to natural turfs,the two types of hybrid turfs had more advantages in playing quality. The results of the 8th week measurement showed that the hybrid turfs were higher in rolling distance,torque,and other indicators than natural turf. In the sports events,it could save more physical energy and benefit sports events,among which the quality of visual and playing of HERO hybrid turf was better than that of X-TRASS hybrid turf. The comprehensive evaluation score for HERO hybrid turf was 6.38,ranking first. In conclusion,hybrid turfs demonstrated significant advantages in both visual quality and playing quality over natural turf. HERO hybrid turf was considered the optimal choice for establishing hybrid turfs. However,practical applications needed to consider how to reduce the surface hardness to prevent the potential risks caused by turfs.

摘要： 为研究践踏对交播多年生黑麦草(Lolium perenne)的不同品牌铺装式混合草坪的影响，本研究以2种(HERO和X-TRASS)混合草坪为试验材料，普通狗牙根(Cynodon dactylon)天然草坪为对照，通过践踏器进行8周处理。结果表明：长期践踏处理下，2种混合草坪的颜色、总密度、盖度等外观质量均优于天然草坪；混合草坪含有人造草纤维，具有保护作用，生物量高于天然草坪；2种混合草坪在运动质量上也具优势,第8周结果表明混合草坪在滚动距离、扭力等指标上高于天然草坪，在实际运动中，更加节省体力，利于体育赛事；其中，HERO混合草坪的外观质量和运动质量等优于X-TRASS混合草坪，其综合评价值为6.38，排名第1位。综上，混合草坪在外观质量和运动质量上均明显优于天然草坪，HERO混合草坪是建植混合草坪的最佳选择，但实际应用中需考虑如何减少表面硬度以降低场地过硬可能带来的风险。
