摘要
为明确豫中烟田杂草种类和群落特征,进而有效防控烟田杂草,对豫中烟田杂草进行了系统调查。结果表明:①豫中烟田杂草共有34种,属16科,其中菊科种类最多,占比为26.47%,其次为禾本科,占比为14.71%。②烟草团棵期共有29种烟田杂草,其中反枝苋、田旋花的相对多度是88.96%和56.96%,为该时期烟田杂草的优势种;铁苋菜、马齿苋、牛筋草、小酸浆、狗尾草、香附子、地锦、刺儿菜、醴肠、马唐的相对多度在11.50%~32.98%之间,为该时期烟田杂草的相对优势种。③烟草成熟期共有32种烟田杂草,其中反枝苋、牛筋草、马齿苋相对多度分别是75.91%、60.74%和59.30%,为该时期烟田杂草的优势种;狗尾草、铁苋菜、小酸浆、地锦、醴肠、香附子的相对多度在11.41%~30.30%之间,为该时期烟田杂草的相对优势种。
In order to clarify the weed species and community characteristics and effectively control weeds in central Henan tobacco fields,a systematic survey on weeds in central Henan tobacco fields was conducted.The results showed that:1)There were 34 weed species belonging to 16 families.The species of Compositae was maximum(accounted for 26.47%),followed by those of Gramineae(accounted for 14.71%).2)At the rosette stage of tobacco plants,there were 29 weed species;in which,Amaranthus retroflxus and Convolvulus arvense were the dominant ones,and their relative abundances were 88.96%and 56.96%,respectively.Acalypha australis,Portulaca oleracea,Eleusine indica,Phsalis minima,Setaria virdis,Cyperus rotundus,Euphorbia humifusa,Cephalanoplos segetum,Eclipta prostrata and Digitaria sanguinalis were relatively dominant weeds,and their relative abundances ranged from 11.50%to 32.98%.3)At the mature stage of tobacco plants,there were 32 weed species;in which,Amaranthus retroflexus,Eleusine indica and Portulaca oleracea were dominant,and their relative abundances were 75.91%,60.74%and 59.30%,respectively.Setaria virdis,Acalypha australis,Phsalis minima,Euphorbia humifusa,Eclipta prostrota and Cyperus rotundus were relatively dominant ones,and their relative abundances ranged from 11.41%to 30.30%.
