    摘要:

    在兰州地区选择河沙、农田土作为草坪根际层基质,以北方地区最常用的 2 种足球场建植草坪草种草地早熟禾(Poa pratensis)和多年生黑麦草(Lolium perenne)为材料,共设上下层含沙量不同的 21 种根际层结构,研究不同根际层结构对足球场草坪质量的影响。结果表明:随着根际层含沙量增加, 草坪成坪时间延长,颜色、质地与均一性呈先下降后上升趋势;草坪强度与反弹率逐渐降低。当根际层上层含沙量为 20% 时,随下层含沙量增加,草坪质量逐渐变差;当上层含沙量为 40%、100% 时,随下层含沙量增加,草坪质量先增高后降低;上层含沙量为 60%、80% 时,随下层含沙量增加,草坪质量先降低后增高再降低。综合评价得出上层含沙量为 60%、下层含沙量为 0 的处理草坪质量最优,其次是上层含沙量为 40%、下层含沙量为 20% 的处理。上、下层均为纯沙的处理草坪质量最差。

    Abstract:

    In this research,river sand and farmland soil were selected as inter‐rhizosphere substrates in Lanzhou. Two most commonly used turf grasses,Kentucky bluegrass and perennial ryegrass,for football field establishment in northern China,were examined. Twenty ‐one inter‐rhizosphere structures with different sand contents in the upper and lower layers were established to study the effects of different inter‐rhizosphere structures on the quality of football field. The results showed that the inter‐rhizosphere structure varied with the sand content of the upper and lower lay‐ ers. As the sand content of inter‐root layer increased,the turf establishment time increased,the color,texture and uniformity decreased and then increased;the turf strength and bounce rate decreased gradually. When the sand con‐ tent in the upper layer of the inter‐rhizosphere was 20%,as the sand content in the lower layer increased the lawn quality gradually deteriorated;when the sand content in the upper layer was 40% and 100%,as the sand content is zero in the lower layer increased the lawn quality first increased and then decreased. When the sand content in the up‐ per layer was 60% and 80%,as the sand content in the lower layer increased the lawn quality first decreased and then increased and then decreased. The overall evaluation concluded that 60% sand content in the upper layer and zero in the lower layer resulted the best turf quality,followed by 40% sand content in the upper layer and 20% sand content in the lower layer,and the turf quality with pure sand in both upper and lower layers led to the worst turf quality for football field.
