分别于2013年、2014年采用倒置“W”9点取样法、七级目测法，调查了四川省德阳市烟田杂草发生的种类及危害；2014年采用田间定点调查法研究了烟田杂草的出苗特点。结果表明：德阳市烟田杂草共24科67种，优势种为光头稗[ Echinochloa colonum （ L．） Link]、马唐[ Digitaria sanguinalis （ L．） Scop．]、繁缕[ Stellaria media （ L．） Cyr．]、碎米荠（ Cardamine hirsuta L．）、辣蓼（ Polygonum flaccidum Meism．）。烟田杂草于2014年的出苗高峰期为烟苗移栽后20～30 d。明确了德阳市烟田杂草的种群特点和发生规律，为有针对性地提出烟田杂草防除措施提供了科学、可靠的理论依据。

Weed species and their damage of weeds in tobacco fields in Deyang were investigated in 2013 and 2014 by using inverted“W” 9-point sampling method and the seven visual method.Emergence characteristics of weeds were sur-veyed at fixed-points in the field in 2014.There were 67 weed species belonging to 24 families.The dominant weed popu-lations were composed by Echinochloa colona ( L.) Link,Digitaria sanguinalis ( L.) Scop.,Stellaria media ( L.) Cyr., Cardamine hirsuta L.and Polygonum flaccidum Meissn.The peak weed emergence occurred between 20 and 30 days af-ter tobacco seedling transplanting in 2014.This study characterized the weed populations associated with tobacco fields , and provides pertinent information to establish appropriate weed control measures.
