摘  要：
为了明确襄阳市主要烟叶产区烟田杂草种类及分布,确定危害烟叶生产的主要杂草种类,为高产优质烟叶生产提供技术支撑,于2011年9月在植烟面积比较大的保康县、南漳县和襄州区的6个乡镇进行了普查。结果表明,襄阳市烟田杂草有50种,隶属于23个科。优势种为马唐(Digitaria sanguinalis)、铁苋菜(Acalypha australis)、尼泊尔蓼(Polygonum nepalense)、牛膝菊(Galinsoga parvifl)和繁缕(Stellariamedia)。发生频度较高的几种杂草依次为铁苋菜、尼泊尔蓼、牛膝菊、马唐和繁缕。根据杂草密度和频度,襄阳市烟田危害最严重的杂草种类为马唐、铁苋菜、尼泊尔蓼、牛膝菊和繁缕,应作为防除重点。海拔高度对杂草的种类及分布有一定的影响,在较低海拔的烟田中杂草种类更多。

摘  要：
In order to clarify the weed species,their distribution and the main noxious species in major tobacco-producing areas in Xiangyang of Hubei province,and to provide technical support for high quality tobacco production,the survey were carried out in 6 towns in Baokang,Nanzhang and Xiangzhou where the tobacco-planting area was large in September,2011.The results showed that there were 50 weed species belonging to 23 families in tobacco fields in Xiangyang.The dominant species were Digitaria sanguinalis,Acalypha australis,Polygonum nepalense,Galinsoga parvifl and Stellaria media.Weeds with high frequency ranked as A.australis,P.nepalense,G.parvifl,D.sanguinalis and S.media.According to weed density and frequency,the most noxious weed species in tobacco fields in Xiangyang ranked as D.sanguinalis,A.australis,P.nepalense,G.parvifl and S.media,which should be focused on in weed control.The altitude had certain influence on weed species and their distribution.There were more weed species at lower altitude.
