摘　　要：以广西壮族自治区南宁市、柳州市和桂林市44个柑橘园为代表,系统地调查了广西壮族自治区柑橘产区的杂草群落结构,结果显示广西柑橘产区柑橘园共有杂草68种,隶属于37个科、65个属。根据物种重要值,确定广西柑橘产区重要值大于1%的杂草为优势杂草,其种类包括马唐、鬼针草、牛筋草、鸭跖草、阔叶丰花草、稗、喜旱莲子草、龙葵、藿香蓟、凹头苋、铁苋菜、酢浆草、狗尾草、碎米莎草、小心叶薯、酸模叶蓼、墨苜蓿、积雪草、狗牙根、乌蔹莓和竹节菜等,其中鬼针草、牛筋草、稗和喜旱莲子草等是广西柑橘产区内发生危害较为严重的恶性杂草。并通过CCA分析发现广西柑橘产区杂草群落结构主要受到年平均降水量、年平均气温、经度、纬度以及海拔等环境因子的影响。本研究明确了广西壮族自治区柑橘产区杂草群落结构及发生现状,对指导柑橘园杂草科学防控具有重要意义。Weed community structure was systematically investigated in 44 Citrus reticulata orchards in Nanning City,Liuzhou City and Guilin City of Guangxi Zhuang Autonomous Region.The results showed that there were 68 species of weeds belonging to 37 families and 65 genera in C.reticulata orchards of Guangxi producing areas.According to the importance value of species,the weeds with importance value more than 1% were determined as dominant weeds.The species included Digitaria sanguinalis,Bidens pilosa,Eleusine indica,Commelina communis,Spermacoce alata,Echinochloa crusgalli,Alternanthera philoxeroides,Solanum nigrum,Ageratum conyzoides,Amaranthus blitum,Acalypha australis,Oxalis corniculata,Setaria viridis,Cyperus iria,Ipomoea obscura,Persicaria lapathifolia,Richardia scabra,Centella asiatica,Cynodon dactylon,Causonis japonica and Commelina diffusa.Among them,B.pilosa,E.indica,E.crusgalli and A.philoxeroides were more serious malignant weeds in C.reticulata producing areas of Guangxi.Through CCA,it was found that the weed community structure in C.reticulata producing areas of Guangxi was mainly affected by environmental factors such as annual average precipitation,annual average temperature,latitude and longitude,and altitude.This study clarified the weed community structure and occurrence status in producing areas of Guangxi Zhuang Autonomous Region,which is of great significance to guide the scientific prevention and control of weeds in C.reticulata orchards.
