Abstract:

A weed survey was conducted using inverted W-pattern sampling methods to determine the species composition and structure of weed communities in wheat fields in Shandong Province. The taxa found included 69 weed species belonging to 21 families and 54 genera. Among these, 10 species were considered dominant weeds, including Descurainia sophia, Capsella bursa-pastoris, Galium aparine, Bromus japonicus, Silene conoidea, Erysimum cheiranthoides, Lithospermum arvense, Alopecurus aequalis, Aegilops squarrosa, and Calystegin hederacea; 15 species were regional dominant weeds and 44 were normal weed species. Fields in the plain regions of southwest Shandong possessed highest species richness, Shannon-wiener index and Evenness index,while the highest Simpson’s index was found in the plain regions of northwest Shandong and coastal regions of north Shandong. Hierarchical cluster analysis revealed that weeds in Shandong Province fall into 4 regional groups: hill regions of east Shandong with plain and mountain regions of mid Shandong; mountain regions of south Shandong and plain regions of southwest Shandong; plain regions of northwest Shandong ; and coastal regions of north Shandong.
