| Abstract: | 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 9 sampling 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. |
