摘要
为明确湖北省冬小麦田杂草的发生危害现状和群落组成特征,运用倒置"W"9点取样法对该省冬小麦主产区麦田杂草群落进行了调查。结果表明,湖北省冬麦田杂草有16科39种,其中禾本科杂草占18%,阔叶杂草占82%。相对多度达15以上的杂草依次为猪殃殃、牛繁缕、日本看麦娘、野老鹳草、野燕麦和大巢菜等6种,其中猪殃殃、牛繁缕和日本看麦娘的相对多度分别为74.19、51.66和30.36,为优势种类。
In order to clarify the species composition and characteristics of weed community in winter wheat fields in Hubei province,field weed survey was conducted using an inverted W-pattern with 9sampling points.Of the 39 weed species recorded in winter wheat fields,18% accounted for grasses and 82% for dicots.Based on the analysis of their relative abundance,catchweed(Galium aparine var.tenerum),aquatic malachium(Malachium aquaticum)and Japanese foxtail(Alopecurus japonicus)with relative abundance above 30,were the most abundant weeds in the area.Carolina cranesbill(Geranium carolinianum),wild oat(Avena fatua)and common vetch(Vicia sativa)with relative abundance between 15 and 30,were important weeds in the area.
