摘  要：
采用倒置"W"9点取样法和七级目测法,调查了攀西烟田杂草发生的种类和危害状况;同时采用田间定点调查法研究了烟田杂草的出苗规律。结果表明,攀西烟田杂草共有30科75属115种,根据相对多度和综合危害指数,最主要的杂草有尼泊尔蓼、马唐、酸模叶蓼、辣子草、光头稗、藜等;烟田杂草有2个出苗高峰,一个在烟草移栽后20~30 d,另一个在烟草揭膜培土后1~10 d,其中以第1个出苗高峰为主。

摘  要：
Species and damage status of weeds in tobacco fields in Panxi of Sichuan Province were investigated using inverted "W" 9-point sampling method and seven visual method in 2013 and 2014. Emergence characteristics of weeds were surveyed by field tenpoint investigation. The results showed that there were 115 weed species in 75 genera belonging to 30 families. According to relative abundance and comprehensive weed damage index, the major noxious weed species included Polygonum nepalense Meisn., Digitaria sanguinalis(L.) Scop., Polygonum lapathifolium L., Galinsoga parviflora Cav., Echinochloa colonum(L.) Link、Chenopodium album L. and so on. There were two peaks of weed emergence in tobacco fields. One was in 20-30 days after tobacco transplanting, which is the major emergence peak. And the other weed emergence peak was in 1-10 days after film uncovering and hilling.
