| 摘 要： | 采用五点取样法对位于广东省北部、中部和南部的部分地区稻田杂草发生种类进行调查，结果表明，广东省稻田主要杂革有48种，分别隶属于15个科。相对优势度计算结果表明，莲子草、鸭跖草、稗草、泥花草、空心莲子草、节节菜等杂草为广东省稻田优势杂草。其中广东北部稻田杂草群落结构以鸭跖草＋稗草＋莲子草为主；广东中部地区稻田杂草群落结构以节节菜＋莲子草＋稗草为主；广东南部地区稻田杂草群落结构以莲子草＋鸭跖草＋泥花草为主。总体来看，广东省稻田杂草发生频度较低，这可能与长期施用除草剂有关。

| Abstract: | Weed communities of paddy fields in the north, middle and south of Guangdong Province were studied by the five - point sampling method. Forty - eight species belonging to 15 families were found. According to their relative abun- dance,Alternanthera sessilis , Commelina communis , Echinochloa crusgalli , Lindernia antipoda,Alternanthera philoxeroides , and Rotala indica were the dominant weeds in paddy fields of Guangdong Province. Reionally,north, middle and south of Guangdong Province were Commelina communis ＋ Alternanthera sessilis ＋ Echinochloa crusgali were dominant in the north, Rotala indica ＋ Alternanthera sessilis ＋ Echinochloa crusgali in the middle and Alternanthera sessilis ＋ Commelina communis ＋ Lindernia antipoda in the south of the province. Overall, the frequencies of occurrence of weeds were low in Guangdong Province, and that was probably due to long - term utilization of herbicides. |
