Dynamic change of production and botanical composition in Tri folium repens and perennial grass mixtures over 20 years in the Karst region,Southwest China

摘要：

White clover ( T ri f olium repens) use is valued for its ability to substitute for fertilizer nitrogen (N) use and to improve pasture quality ( Thomson 1984).It was introduced into the Karst region of China at least 100 years ago ; however, its persistence and compatibility with grasses in the mixture still remains unclear.
