Weeds invading and the competition impact in turf

Totally 85 turf plots on campus of Huazhong Agricultural University were investigated regarding invasive species, and then 17 typical plots with different light conditions, ages and management levels were used to determine the important value of each species in order to identify the statue and competition ability in community. The results showed that there were about 141 invasive species that belongs to 39 families. Those species from Compositae, Papillionaceae, Pmbelliferae and Caryophyllaceae became dominants through competition. The competition ability and distribution for the invasive species were affected by sunlight, soil, species characteristics and turf management level. All management approaches, such as shading, irrigation, soil loosing, fertilization and weeds controlling, were the direct factors affecting competition ability of invasive species.
