中文摘要	【目的】研究新疆荒漠绿洲区甘薯田杂草组成及群落特征,为科学防控甘薯田杂草提供理论依据。【方法】采用倒置W法9点取样,对新疆荒漠绿洲区甘薯田杂草进行系统的调查。【结果】新疆荒漠绿洲区甘薯田杂草有46种,隶属于19科42属,其中禾本科10种、菊科8种、藜科5种、豆科3种、蓼科3种,其它科1~ 2种。相对多度大于1的杂草有20种,其中优势杂草有7种,分别为马唐Digitaria sanguinalis、马齿苋Portulaca oleracea、稗草Echinochloa crusgalli、田旋花Convolvulus arvensis、反枝苋Amaranthus retroflexus、藜Chenopodium album、无芒稗Echinochloa crusgalli var.mitis,常见杂草有13种,分别为龙葵Solanum nigrum、野西瓜苗Hibiscus trionum、牛筋草Eleusine indica、小画眉草Eragrostis minor、狗尾草Setaria viridis、苣荬菜Sonchus arvensis、芦苇Phragmites communis、苦苣菜Sonchus arvensis、曼陀罗Datura stramonium、大蓟Cirsium japonicum、虎尾草Chloris virgata、节节草Equisetum ramosissimum和艾蒿Artemisia argyi,还分布有一般性杂草26种。【结论】优势杂草中危害最重的杂草是马唐、马齿苋和稗草,其相对多度分别为16.29、13.27和11.36。核桃-甘薯间作甘薯田杂草群落优势集中性指数为0.18,高于甘薯单作田,而杂草群落多样性指数和均匀度指数分别为2.25和0.60,低于甘薯单作田。
英文摘要	【Objective】To clarify the weed species composition and community structure in sweet potato fields in desert oasis region of Xinjiang.【Method】The weeds of sweet potato fields were investigated using the method of inverted W-pattern with 9 sampling points.【Result】The results showed that 46 weed species belonged to 42 genera of 19 families in sweet potato fields in desert oasis region of Xinjiang.There were 10 species of Gramineae,8 species of Compositae,5 species of Chenopodiaceae,3 species of Leguminosae,3 species of Polygonaceae and 1-2 species of other families.There were 20 species of weeds whose relative abundance were more than 1.The dominant weeds in sweet potato fields were Digitaria sanguinalis,Portulaca oleracea,Echinochloa crusgalli,Convolvulus arvensis,Amaranthus retroflexus,Chenopodium album and Echinochloa crusgalli var.mitis.The common weeds were Solanum nigrum,Hibiscus trionum,Eleusine indica,Eragrostis minor,Setaria viridis,Sonchus arvensis,Phragmites communis,Sonchus arvensis,Datura stramonium,Cirsium japonicum,Chloris virgata,Equisetum ramosissimum and Artemisia argyi,the other 26 weed species were normal weeds.Among the dominant weeds,the most harmful weeds were Digitaria sanguinalis,Portulaca oleracea,Echinochloa crusgalli,the relative abundance of which were 16.29,13.27 and 11.36.【Conclusion】The dominant index of weed community in walnut-sweet potato intercropping field was 0.18,higher than that in sweet potato monocropping field,while the diversity index and evenness index of weed community were 2.25 and 0.60,lower than those in sweet potato monocropping field,respectively.This indicated that the dominant weeds were concentrated in walnut-sweet potato intercropping field,and the damage was higher than that in sweet potato monoculture field.The weed species and community structure in sweet potato fields in desert oasis region of Xinjiang were clarified,which provided a theoretical basis for the scientific control of weeds in sweet potato fields.
