%X Influences of nutrient (N and P) treatments on N and P concentrations and N:P stoichiometric ratio were studied in roots of urban ground cover plant species dwarf lilyturf (Ophiopogon japonicus (Thunb.) Ker-Gawl). N and P concentrations were determined during October to December after treatment. The average N concentration in roots followed the order: N(5 g m-2) P(1 g m-2) addition> N (5 g m-2) addition = P (1 g m-2) addition > control. Compared with control, significant changes in N and P concentrations of roots as well as N:P stoichiometry ratio were found in October, and none was found during November to December. It was indicated that N and P levels in dwarf lilyturf roots could be maintained stably under high N and P input. Thus, dwarf lilyturf has high ability to adapt N deposition, especially been fertilized with P. Therefore, dwarf lilyturf could be used as a good plant species in N deposition area.
