摘要：坪床是保持运动场草坪耐践踏性和持久性的关键。不同的坪床结构由于理化性状的差异，会对草坪草的生长发育和运动功能产生深刻的影响，在建坪初期首先体现为成坪效果的不同。本试验以我国校园足球场最常使用的中粗沙、细沙和田园土三种坪床为基础，以运动场草坪广泛使用的海 雀稗（Paspalum vaginatum）、杂交狗牙根（Cynodon dactylon • C. transvaalensis）和中华结缕草（Zoysia sinica）三种草坪草为研究对象，通过比较三种坪床的土壤理化性状以及三种草坪草的成坪效果，为进一步研究低成本坪床结构配比和养护管理关键技术奠定基础。实验结果表明：砂基坪床土壤饱和透水率以及入渗率明显高于田园土型坪床，体现良好的透水透气性，同时植草前砂基坪床0-10cm土层土壤紧实度低于田园土型坪床；但是田园土型坪床土壤与砂基坪床土壤N、P、K、Fe、Zn等养分流失情况差异较大，体现为细沙型坪床>中粗沙型坪床>田园土型坪床，砂基坪床养分流失较严重；从草坪的草坪密度、叶宽、叶色、坪面温度等坪用指标来看，海雀稗、杂交狗牙根在砂基坪床建坪效果优于田园土型坪床，同时中粗沙型坪床优于细沙型坪床，中华结缕草草坪在田园土型坪床上表现最佳。29803

Effects of Turf-bed Structures on Turf Establishment of Three Different Turf-grass Species
Abstract: Turf-bed is the key to maintain the traffic tolerance and persistence of sports field. Different turf structures will have profound influence on growth and development of turf-grass and sports functions, because of different physical and chemical properties, and it will express as different turf establishment in the initial stage of the construction. This experiment bases on rural soil, fine sand, and medium-coarse sand which are most frequently used in our country, and takes seashore paspalum (Paspalum vaginatum)、hybrid bermudagrass (Cynodon dactylon • C. transvaalensis) and zoysia sinica, according to the evaluation on the establishment effect of different sports turf-grass species in different turf-beds, in order to study further for traffic tolerance of different species on different turf-beds and low cost maintenance and management of key technology to lay the foundation. According to the results of this experiment, it shows that the soil saturated hydraulic conductivity and infiltration rate of sand-based turf-beds are obviously higher than rural soil turf-bed, which means fine water and air permeability. And before planting grass, the soil compaction of sand-based turf-bed is lower than rural soil turf-bed’s on 0-10cm layer. But there are big differences between rural soil turf-bed and sand-based turf-bed on nutrient loss of N, P, K, Fe, Zn, which shows like fine sand turf-bed > medium-coarse sand turf-bed >rural soil turf-bed, it shows that sand-based turf-beds lose nutrient seriously. According to turf indexes of turf density, leaf width, leaf color, turf temperature, the turf establishments of seashore paspalum and hybrid bermudagrass on sand-based turf-beds are better than rural soil turf-bed, sand-based turf-bed is better than soil turf-bed’s, and medium-coarse sand turf-bed’s is better than fine sand turf-bed’s, and as for zoysia sinica, the turf establishment on rural soil turf-bed is the best type.
