摘  要：
Weeds were surveyed in tea gardens in Guizhou Province to assess their harmfulness and to provide a basis for effective weed control. A total of 152 weed species(including varieties) belonging to 42 families and 122 genera were found in tea gardens,including 11 dominant weeds,10 regionally dominant weeds,20 common weeds,and 111 general weeds. The dominant weeds were Digitaria sanguinalis,Stellaria media,Crassocephalum crepidioides,Hypolepis punctate,Conyza canadensis,Imperata cylindrica,Artemisia lavandulaefolia,Ageratum conyzoides,Bidens pilosa,Galinsoga parviflora and Kalimeris indica. Tea gardens varied in their weed communities thus adult tea gardens had a greater proportion of perennial weeds and contained more weed species than young gardens; annuals were the main occurring weeds in both gardens.
