摘　　要：采用倒置“W”9点取样法对贵州省不同区域茶园杂草进行调查,以明确贵州省茶园杂草发生危害特点,为贵州省茶园杂草防控提供依据。结果表明,贵州省茶园杂草有152种(含变种),隶属于42科122属,其中优势杂草11种,区域性优势杂草10种,常见杂草20种,一般杂草111种,以马唐、繁缕、野茼蒿、姬蕨、小蓬草、白茅、野艾蒿、胜红蓟、鬼针草、牛膝菊、马兰等为优势杂草;不同区域茶园杂草群落存在一定差异,对于成年茶园,其杂草发生种类,多年生杂草发生比例较幼龄茶园高,但二者均以一年生杂草发生为主。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.
