Abstract

Abstract: In order to understand the effects of different nutrient additions on the grassland community,simulated experiments of artificial addition of nitrogen,phosphate and potassium fertilizers were conducted to study the changes in element contents of carbon (C),nitrogen (N) and phosphorus (P) in plant leaves and the stoichiometric ratios of plant C∶N,C∶P,N∶P and C∶N∶P under different fertilization levels.The results showed that the dicotyledonous plants Artemisia laciniata and Thalictrum squarrosum could better absorb the nutrients in fertilizer than monocotyledonous Leymus chinensis,Stipa baicalensis and Carex pediformis,and the dicotyledonous plants had higher storage.

Key words: Fertilization;Grassland communities;Stoichiometric ratio
