摘要
为明确河南省小麦田杂草发生情况,从而制定合理、有效的杂草防除策略,对河南省10地市15个县(市、区)小麦田杂草发生情况进行了调查分析。结果显示,河南省小麦田主要杂草有17种,其中禾本科杂草4种,阔叶杂草13种。阔叶杂草播娘蒿、猪殃殃、荠菜在河南省发生较为普遍,成为小麦田恶性阔叶杂草,而禾本科杂草节节麦近年来发生逐步加重,成为麦田杂草防治的难点。河南省不同地区草相有较大差异,杂草发生呈现区域分化特点。南阳地区杂草的种类最为丰富,达2.93种/m2;而信阳地区的杂草发生密度最大,达158.00株/m2,危害最严重。河南省杂草总体发生情况呈现由北向南逐渐加剧的态势。
Defining the occurrence of weed in wheat fields is important for formulating weed management methods. This study focused on the surveying of weed in wheat fields in 15 counties( cities,districts) of Henan province. There were mainly 17 species(13 dicots and 4 monocots) of weeds in Henan province.Flixweed( Descurainia sophia),Shepherd 's purse( Capsella bursa-pastoris),cleavers( Galium aparine)and Tausch'goatgrass( Aegilops tauschii) were the most noxious weeds in wheat fields. The occurrence of weed was diverse in different regions. The weeds were most varied and abundant in Nanyang( 2. 93 species / m2),and most serious in Xinyang(158. 00 plants/m2). Generally,the harm of weeds was getting worse from north to south.
