摘要
位于青藏高原的青海天然草地,是世界上高寒类牧草的种质资源库。天然草地上野生牧草的优良品质,如抗寒、抗旱等抗逆基因和特殊种性是在世界其他地区所无法寻觅的,也是弥足珍贵的种质资源。据2007年调查统计,青海省有禾本科植物59属257种32个亚种及变种,并且已经有不少引进种和栽培种,已成为高寒牧区适宜种植的当家品种。因此,保护青海天然草地上极具挖掘潜力的牧草种质资源,深入研究和合理开发利用牧草资源是十分必要的。
Qinghai - Tibetan Plateau is a germplasm pool for alpine grass. Cold resistance and drought resistance gene of many fine Gramineae are valuable germplasm resource. From investigation and vital statistics in 2007, there are many 59 genus 257 species 32sub - species and change species. There are many fine forage are intro- duced and cultivated and also to be suitable fine forage in alpine area. So further study and sustainable utiliza- tion is very necessary.
