我国本地假俭草的特性与应用

Characteristic and Application of Chinese Local Centipedegrass

在简要介绍假俭草的生态分布及生境类型的基础上,详细介绍了假俭草的耐荫、抗病、抗虫、耐践踏、耐瘠薄、耐旱、耐寒、耐药、抗污染等特性,并与其它暖季型草种进行了比较。回顾了假俭草遗传多样性研究、育种等方面的进展及应用情况。提出假俭草新品种可实现草坪的"少修剪、不打药、不施肥、不灌溉"的低养护管理目标,其推广应用可最大限度地降低草坪的养护成本,为我国城市绿地及球场建设做出贡献。建议在广泛收集全国野生假俭草种质资源的基础上,加强新品种选育工作,培育优良品系,加大引种繁育力度,扩大其适应地域,以提高假俭草利用率,促进我国草业的发展。

This study briefly introduced the ecological distribution and habitat types of centipedegrass firstly.On this basis，centipedegrass′s shade tolerance，disease resistance，insect resistance，trampling resistance，barren tolerance，drought resistance，cold resistance，drug resistance and anti pollution characteristics in detail were described，and it was compared with other warm season grass species.The progress of genetic diversity researching，breeding and application of centipedegrass were reviewed.The main argument was that new varieties of centipedegrass could realize the lawn ‘less pruning，not drugs，no fertilizer，no irrigation’，and its popularization and application could reduce the maintenance cost of lawn to the greatest extent，and contribute to the construction of urban green space and stadium.The suggestions were as follows，based on extensive collection of germplasm resources of wild centipedegrass in the country，we could strengthen the work of breeding new varieties，increase the introduction and breeding efforts to expand its regional adaptation，improve the utilization rate of centipedegrass，so as to promote the development of grass industry in China.
