新疆南疆棉田杂草组成及群落特征OA
Composition and community characteristics of weeds in cotton fields in southern Xinjiang
为明确新疆南疆棉田杂草种类及群落分布特征,于2023年-2024年采用倒置"W"九点取样法对南疆3个主要棉花种植区域的130块样地、1170个样方的杂草种类和数量进行系统调查.结果表明:南疆棉田杂草共有42种,隶属于 12 科 38 属,其中藜 Chenopodium album、灰绿藜 Oxybasis glauca、龙葵 Solarium nigrum、稗 Echinochloa crus-galli和狗尾草Setaria viridis是南疆棉田的优势杂草,以上杂草在棉田平均相对多度≥9.98,生态位重叠值≥0.966.南疆棉田杂草具有较广的生态适应性,已形成了稳定的生态系统.群落聚类分析后将南疆棉田杂草群落划分为6组,明确了各组的优势杂草种类.本研究通过解析南疆棉田杂草组成及群落特征,可为南疆棉田区域性杂草综合防控提供参考和依据.
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.
