摘要 采用野外调查与室内栽培相结合,对贵州省烟田杂草优势种群幼苗进行了观察。描述了狗尾草、早熟禾、马唐、小藜、阿拉伯婆婆纳、宽叶母草、牛繁缕、繁缕、猪殃殃、三叶鬼针草、牛膝菊和小飞蓬等12种杂草的幼苗形态,并根据以上杂草幼苗的主要特征编写了检索表,可更好地对优势种杂草幼苗进行识别与鉴定。 Combining indoor cultivation and identification with field survey, we observed the seedlings of dominant weed species in tobacco fields in Guizhou province, described the morphological characteristics of seedlings of 12 weed species ( Setaria viridis, Poa annua, Digitaria adscendens, Chenopodium serotinum, Veronica persica, Lindernia nummlu arifolia,M alachium aquaticum, Stellra ia media, Galium aparine, Bidens pilosa, Galinsoga pavr iflora and Conyza canadensis) , and wrote an identification key based on the main characteristics of these weed seedlings, in order to preferably recognize and identify the seedlings of dominant weed species in tobacco fields.
