龙须草(Eulaliopsis binata)是一种特色野生生物资源,是优质造纸原料和防止水土流失的优良草种。以往针对龙须草种质资源收集和评价研究近于空白。本文通过对中国内陆龙须草种质资源集中分布的9省20县的实地考察,收集了20个居群的龙须草样本,分析了龙须草种质资源生境的主要特征,并对龙须草种质资源主要经济性状进行比较。结果表明:收集的龙须草种质资源集中分布于22°–34° N、101°–114° E,海拔集中在100–1,000 m,年平均气温在14–22℃,年日照时数在1,112–2,624 h,年平均降水量在642–2,330 mm之间。气候因子主成分分析显示,龙须草分布受温度与降水量影响较大,其次为海拔和日照时数。不同...

Eulaliopsis binata, a typical wild living resource, is an excellent grass species which is used as material for papermaking and can prevent water loss and soil erosion. Since there are few studies examining the resource collection and assessment of E. binata, in this paper we attempt to use field studies on concen- trated areas of Chinese E. binata germplasm resources in 20 counties in nine provinces, collect 20 kinds of E. binata germplasm resources, analyse the principal living environmental characteristics of collection areas of E. binata ge...
