摘要

可拆卸的模块化草皮带有沙基根区,是高端体育场的解决方案,可以在草皮上组织各种活动。然而,在模块化草皮的运输过程中,沙子的稳定性低,导致沙子严重渗漏,降低了草皮的均匀性和安全性。先前的研究表明,添加椰纤维(CF)和聚丙烯酰胺(PAM)可以提高土壤稳定性。在本研究中,我们评估了CF和不同量PAM对种植高羊茅(Festuca elata Keng ex E.Alexeev)的沙基模块化草坪在模拟运输振动过程中的土壤性质、草坪草生长、抗剪强度和漏沙的综合影响。每种处理包括0.4%(材料重量/土壤重量)CF和六种浓度的PAM(0%、0.025%、0.050%、0.075%、0.100%、0.125%,w/w)在沙基根区的混合物,不添加CF或PAM作为对照。结果表明,在沙基根区,CF可以改善高羊茅的生长、抗剪强度和抗由于椰纤维的物理性质引起的传输振动而导致的漏砂性。然而,CF和0.100%PAM的联合作用对高羊茅的生长、抗剪强度和抗漏砂性能更好。然而,由于PAM的润滑作用,添加低(≤0.025%)或高比例(≥0.125%)的PAM会降低CF和PAM的效果。因此,CF的综合效应 + 0.100%PAM对草坪模块化效果最好,可作为可移动模块化草坪的应用方案。

Transportation sand leakage and turf performance of sand-based removable modular turf as affected by the combined action of coir fiber and polyacrylamide
Removable modular turf with a sand-based rootzone is a solution for high-end stadiums which can organize various events on the turf. However, the low stability of sand leads to serious sand leakage during the transportation of modular turf, which reduces the evenness and safety of the turf. Previous studies have shown that adding coir fibers (CF) and polyacrylamide (PAM) will improve soil stability. In this study, we evaluated the combined effects of CF and different amounts of PAM on soil properties, turfgrass growth, shear strength, and sand leakage during simulated transport vibrations in a sand-based modular turf planted with tall fescue ( Festuca elata Keng ex E. Alexeev). Each treatment comprised a mixture of 0.4% (weight material/weight soil) CF and six concentrations of PAM (0%, 0.025%, 0.050%, 0.075%, 0.100%, 0.125%, w/w) in the sand-based rootzone, with no addition of CF or PAM as the control. The results show that, in the sand-based rootzone, CF could improve tall fescue growth, shear strength, and resistance to sand leakage owing to transport vibration due to the physical properties of the coir fiber. However, the combined effect of CF and 0.100% PAM was better for tall fescue growth, shear strength, and resistance to sand leakage. However, owing to the lubricating effect of PAM, adding a low (≤0.025%) or a high rate (≥0.125%) amount of PAM would reduce the effect of CF and PAM. Therefore, the combined effect of CF + 0.100% PAM in this study had the best effect on the turf module and can be used as an application scheme for the removable modular turf.
