摘要:

研究果园杂草区系特征可为果园林业环境管理、生态保护和发展提供理论支撑。通过样方法实地调查及信息检索,对广西全区澳洲坚果园地杂草的组成、地理成分及侵袭性进行分析和讨论。结果显示,广西澳洲坚果园地杂草共有77种,隶属33科70个属,其中外来入侵杂草30种13科28个属,主要为菊科和禾本科。杂草科,属地理类型和特征差异显著,科水平上以热带性质为主,地理成分相对简单;属的类型丰富且属级分化程度极高、地理成分复杂。根据不同区域出现的频次,广西澳洲坚果园地杂草分布15个常见属,外来入侵杂草占比较大,入侵程度较深,入侵性严重。在30种外来入侵杂草中,有16种危害程度尚未确定,需开展更深入、全面的果园杂草研究,以更好地管理杂草,减轻其对果园林业和生态环境的潜在危害。

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.
