湖北省花生主产区花生田杂草种类与群落特征
Diversity and characteristics of weed communities in peanut fields of main growing regions in Hubei Province
摘要
Abstract
In order to clarify weed diversity and characteristics of weed communities in peanut fields of main growing regions in Hubei Province,field weed survey was conducted using an inverted W-pattern with 9 sampling points.A total of 76 weed species belonging to 24 families were found,including 4 dominant species,6 regional dominant species,10 minor species,and 56 sporadic species.The relative abundance (RA) of Digitaria sangui-nalis,Eclipta prostrate,Commelina bengalensis and Acalypha australis were higher than those of other weed spe-cies.They were the dominant weeds in all main peanut regions in Hubei Province.The most common weed commu-nities were Eclipta prostrate + Digitaria sanguinalis + Commelina bengalensis in peanut fields in northeastern Hubei Province,and Digitaria sanguinalis + Acalypha australis + Commelina bengalensis + Eclipta prostrata in northern Hubei Province.The variety and diversity of weeds in peanut fields in northeastern Hubei were greater than those in northern Hubei,but the Simpson index was relatively lower.关键词
