Abstract：The expariment aimed to explore the nutritional quality of Urticaceae plants in Hunan grassland and screen high-quality Urticaceae plants.Thirty-three parts of Urticaceae plant germplasm(11 parts in vegetative period,17 parts in flowering period,five parts in maturation period)were collected in Hunan grassland,and dry matter(DM),crude protein(CP),ether extract(EE),crude fiber(CF),crude ash(Ash),nitrogen free extract(NFE)content were determined and analyzed,and the grey relational degree was used to comprehensively evaluate.The results showed that the DM content of 11 germplasms during the vegetative period was between 19.29％to 37.50％,the CP content was between 7.09％to 15.13％,the EE content was between 0.67％to 3.55％,the CF content was between 25.82％to 42.27％,the Ash content was between 5.43％to 14.55％,and the NFE content was between 35.17％to 47.84％.The DM content of 17 germplasms during the flowering period was between 9.90％to 48.00％,the CP content was between 7.86％to 17.72％,the EE content was between 1.33％to 3.36％,the CF content was between 18.96％to 35.69％,the Ash content was between 8.47％to 18.56％,and the NFE content was between 40.17％to 53.10％.The DM content of five germplasms during the maturation period was between 10.12％to 39.39％,the CP content was between 8.48％to 11.41％,the EE content was between 2.43％to 3.41％,the CF content was between 23.18％to 32.90％,the Ash content was between 10.34％to 13.49％,and the NFE content was between 43.53％to 52.48％.The study indicates that during the vegetative stage,Pilea plataniflora attains a higher comprehensive rating,during the flowering stage,both Pellionia scabra achieve higher comprehensive ratings,and at the maturation period,Boehmeria longispica demonstrates a higher comprehensive rating.
