Abstract: It is very important to identification and evaluation of ramie germplasms resistant to barren land for ecological restoration and economic production on barren land a mountain slope. In this study, the poor-soil-fertility tolerance of ramie was tested by cultivated 10 ramie germplasms in the flatland, slopeland and pot. The plant height, tiller number, leaf number, leaf area, leaf SPAD, total fresh weight, total dry weight, fiber weight, nitrogen use efficiency, potassium fertilizer use efficiency were evaluation indicators. The index and classification of poor-soil-fertility tolerance were comprehensively analysised using principal component analysis, membership functionand cluster analysis. Evaluation index of poor-soil-fertility tolerance can be done by tiller number, total fresh weight, leaf area, leaf SPAD value, leaf number, nitrogen use efficiency and potassium fertilizer use efficiency. Membership function of each character were analysised, 10 ramie varieties can be divided into two kinds, the stronger poor-soil-fertility tolerance germplasm were Lengshuijiangyema, Liuyangyema; The weaker poor-soil-fertility tolerance germplasm were Xiangzhu-3,Tri-1, Xiangzhu X2, Xiangzhu X1, Xiangzhu X3, Xiangzhu XB, Zhongzhu-1, and Changshayema. The evaluation index of poor-soil-fertility tolerance was established in ramie. And the ramie germplasms with higher poor-soil-fertility tolerance was screened and identificated.
