摘  要:本研究系统调查海南南繁区玉米田的杂草种类,确定玉米田的杂草优势种群,并提出杂草防除的技术措施。调查结果表明,南繁区玉米田杂草共有21科100种,其中优势杂草主要有牛筋草、红尾翎、短颖马唐、龙爪茅、香附子、异型莎草、碎米莎草、粟米草、伞房花耳草、野甘草、少花龙葵等11种。鉴于南繁区农田杂草种类繁多,在杂草防治措施上应采取植物检疫、人工防除、物理机械及化学防除相结合的综合防除技术,以控制玉米田杂草的发生危害。A systematic investigation on weed types and their dominance was undertaken in corn fields of Hainan National Breeding and Multipliation area to propose suitable control measures.There were 100 weed species belonging to 21 botanical families.Eleven species were considered as the dominant weeds:Eleusine indica,Digitaria radicosa,Digitaria setigera,Dactyloctenium aegyptium,Cyperus rotundus,Cyperus difformis,Cyperus iria,Mollugo stricta,Hedyotis corymbosa,Scoparia dulcis,and Solanum americanum.Given the diversity of weeds in the Hainan National Breeding and Multiplication area,weed control measures should be based on the adoption of multiple techniques combining plant quarantine,artificial control,physical and mechanical control,and chemical control.
