Effects of reinforcement materials on the quality and turf-bed performance of turf in a mobile sports field

The ‘Titanium 2LS’ variety of Festuca arundinacea was used as the test material, and the mobile sports field turf without reinforcement material was used as control (CK). The performance of turf-bed and quality of movement was investigated by simulating medium intensity trampling with a tramper so as to study the effects of curing agents and plant fibers on the quality of mobile sports turf. The results showed that 2 weeks before trampling, 0.4% fiber mesh (XW) treatment significantly improved the color, normalized vegetation index, and turf quality evaluation parameters (P < 0.05). There was no significant difference between results for the quality evaluation analysis of Jipingguan and CK (P > 0.05). 1% polyurethane (WOH) treatment could effectively maintain soil compaction, (0.4% coconut silk + 0.1% polyacrylamide)YP significantly improved surface hardness and torsional friction of turf, whereas YP treatment significantly increased the risk of head injury in players (P < 0.05). After 4 weeks of trampling, the structure of the turf-bed was disturbed by trampling, and the reinforcement performance of each reinforcement material treatment decreased significantly (P < 0.05). To summarize, under moderate trampling intensity, the use of WOH in the reinforcement material in the turf-bed of the mobile stadium can effectively ensure the stable structure of the turf-bed to reduce the risk of player injury and meet the quality requirements of high-quality stadiums.
