摘　　要：为解决沙基运动场草坪在其投入使用初期表面缺乏稳定性的问题,本研究对3种植物纤维废弃物(废旧棉花、麦秆以及椰糠)作为坪床加固材料的可行性进行了分析。试验草坪采用草地早熟禾(Poapratensis)草皮密铺建植,以纯沙坪床基质(CK)作为对照,按质量比混入1%废旧棉花(T1)、1%麦秆(T2)以及1%椰糠(T3)作为处理,研究各坪床基质对草坪外观质量、土壤条件以及运动质量的影响。结果表明,与CK处理相比,T1、T2以及T3处理均能提升草坪色泽,促进草坪分蘖,提高草坪外观质量,其中T3处理最佳,T2处理次之;T1、T2和T3处理均能增强土壤持水性,增大土壤紧实度以及抗剪强度,其中T3处理能显著增强土壤持水性和增大土壤抗剪强度(P<0.05),而T1处理则能显著增大土壤紧实度以及抗剪强度(P<0.05);各处理草坪运动质量(扭动摩擦性能、表面硬度、回弹性)均符合运动场草坪质量相关评价标准。由此表明,废旧棉花、麦秆以及椰糠均可作为沙基运动场草坪坪床加固材料,其中添加1%废旧棉花(T1)处理坪床加固效果最佳,值得在运动场草坪建植中推广应用。In order to solve the problem of the lack of stability of the sand-based sports turf at the beginning of its operation, the feasibility of using three plant fiber wastes (waste cotton, wheat straw and coconut chaff) as reinforcement material for turf rootzone was analyzed in this trial. The trial turf was planted with Kentucky bluegrass (Poa Pratensis) sod. Taking the pure sand rootzone substrate (CK) as control, 1% waste cotton (T1), 1% wheat straw (T2), and 1% coir dust (T3) were mixed into the rootzone according to the mass ratio to study the effects of each rootzone substrate on the appearance quality, soil conditions and playing quality of the turf. The results showed that compared with CK treatment, T1, T2 and T3 treatment could improve turf color, tillering and appearance quality, among which T3 treatment was the best, followed by T2 treatment. T1, T2 and T3 treatments can improve soil moisture content, compaction and shear strength, of which T3 treatment can significantly increase soil moisture content and shear strength (P < 0.05), while T1 treatment can significantly increase soil compaction and shear strength (P < 0.05). The playing quality of turf (rotational traction performance, surface hardness, resilience) in all treatments conformed to the quality evaluation standards for the sports turf. These results showed that waste cotton, wheat straw and coir dust can be used as reinforcement materials for sand-based sports turf rootzones, and the treatment by mixing 1% waste cotton in the rootzone (T1) has the best reinforcement effect, which is worthy of popularizing and applying in the establishment of sports turf.
