新疆南疆棉田杂草组成及群落特征
Composition and community characteristics of weeds in cotton fields in southern Xinjiang
摘要
Abstract
To clarify the community characteristics of weeds in cotton fields in southern Xinjiang,a comprehensive survey of weed species and their abundance were conducted in 1 170 sample plots in 130 cotton fields using the inverted"W"9-point sampling method.The results showed that 42 weed species belonging to 12 families and 38 genera,and Chenopodium album,Oxybasis glauca,Solanium nigrum,Echinochloa crus-galli and Setaria viridis were dominant species in cotton fields in southern Xinjiang.The average relative abundance of dominant weeds in cotton field were greater than 9.98,and overlapping on niches were greater than 0.966.The weeds in cotton fields in southern Xinjiang demonstrated broad ecological adaptability,contributing to the formation of a stable ecosystem.The weed communities in cotton fields were divided into 6 groups by community cluster analysis,and dominant weed species of each group were identified.The above results will provide reference and basis for comprehensive regional weed control in cotton fields in southern Xinjiang.关键词
