Abstract:

Understanding the floristic characteristics of orchard weeds c is essential for supporting effective management,ecological protection,and development of orchard forestry environments.Using field surveys and literature reviews,we analyzed the composition,geographic distribution,and invasiveness of weeds in Macadamia orchards across Guangxi.Theresults identified 77 weed species from 33 families and 70 genera,including 30 invasive alienspecies from 13 families and 28 genera,primarily from the Asteraceae and Poaceae.The distribution patterns of weed families and genera show significant differences among geographical types,with tropical characteristics dominating at the family level and relatively simple overall geographic composition.Based on the frequency of occurrence in different regions,15 common genera of weeds were identified in Macadamia orchards in Guangxi,many of which were dominated by invasivealien species,indicating a high degree of invasiveness.Among the 30 identified invasive alien weed species,the harmfulness of 14 remains undetermined to be clarified through further investigation.Further in-depth and comprehensive research is required to improve weeds management strategies and mitigate the potential threats to orchards forestry and the ecological environment.
