On the basis of several years' research, 219 turfgrass cultivars belonging to 17 species and 11 genera were introduced and collected. Through systematical observation and evaluation, 27 superior cultivars with good adaptability to the soil and climate of Tianjin were selected, including cold season turfgrass-tall fescue, warm season turfgrass-buffalograss and Zoysia japonica. The resource pool of turfgrass including over 200 cultivars were set up. During the research of seed propagation technology of tall fescue, its growth rule in Tianjin was grasped; the best sowing rate, appropriate sowing period and the best harvesting time were determined, which established the good base for the lawn research in Tianjin.%在多年研究的基础上,引进与收集草坪草种11个属、17个种,共219个品种,通过系统的观察、评价,筛选出适合天津土壤气候条件的优良草种27个品种,其主要为冷季型草坪草高羊茅Festuca elata和暖季型草坪草野牛草Buckloe dactvloides及日本结缕草Zoysia japonica,并建成品种达200个以上的草坪草种资源库;通过高羊茅种子繁育技术研究,掌握了高羊茅在天津市的生长发育规律,研究出高羊茅种子繁育的最佳播量、适宜播期、最佳收获期等,为天津市今后的草坪研究工作打下了良好的基础.
