%X The plasticity of clonal architecture of Juema in response to N element was studied.The results show that the root length of genet,branch number,ramet number,spacer,shoot dry weight and root dry weight show a Conic curve with the increase of N element,and when 90.0 kg/hm~2 of N element is applied an inflexion appears,showing that Juema has plasticity in response to heterogeneity resource of N element.The changes of total branch length,expending rate of root and ball root rate decline with the increase of N element,which shows that after using N,the root tuber of Juema has not a commercial value.After the renew of ecology,the proper N fertilizer can boost the shoot weight and vegetation covering rate.
