摘要: 美国于1895 年从中国东北地区引进结缕草, 后又从中国、朝鲜和南亚地区引入10 多种结缕
草。自20 世纪80 年代以来, 美国由于环境胁迫和病害严重, 造成了过渡带气候区冷季型草坪草质量下降,引起了暖季型草坪草(特别是结缕草栽培种) 应用的增加, 他们将选育出的许多结缕草品种广泛种植于南方和过渡带气候区。然而中国却在1990 年后从美国购买大批量的冷季型草坪草草籽种植于几乎所有的城市, 出现了诸多问题。借鉴历史事实, 对中国发展草坪国产化是有益的。

Abstract: Zoysia japonica Steud. was first introduced to USA from the northeast part of China in 1895. After that , more than 10 species of Zoysia grasses were introduced from China , Korea and other South-Asia areas.Since 1980ps , the warm-season turfgrasses , particularly Zoysiagrass cultivars , have been increasingly used because of the decline in quality of the cool-season turfgrasses as a result of environmental stresses and diseases in the transition regions between cool and warm climates in USA. Several types of new Zoysia grass cultivars have been selected , bred , and planted in the South and transition regions in USA. On the other hand , China has been importing large quantities of the cool-season turfgrass seeds from USA since 1990's and planted them in almost every city in the country. Many problems with the cool-season turfgrasses have recently surfaced in China. This paper will discuss the valuable lessons that other countries have learned , and will offer suggestions for the development of the domestic industrialization of turfgrasses in China.
