| 摘 要： | 为了弄清南繁区转基因水稻田、非转基因水稻田和空白对照田杂草种类及发生情况，采取5点取样法，对3种田的田间杂草种类及危害情况进行了调查。结果表明：转基因水稻田有杂草19种，隶属11科，优势杂草为空心菜、牛毛毡、水莎草、莲子草、水苋菜、千金子，相对多度分别为37．58％、28．51％、26．24％、21．70％、21.62％、20．84％；非转基因水稻田主要杂草包括17种，隶属10科，优势杂草为空心菜、水莎草、牛毛毡、莲子草、水苋菜，相对多度分别为40．14％、29．83％、29．83％、24．11％、21．70％；空白对照田主要杂草包括12种，隶属8科，优势杂草为空心菜、水莎草、水苋菜、碎米莎草、莲子草、鳢肠，相对多度分别为60．28％、36．76％、34．98％、33.80％、29．11％、23．25％；水稻田（转基因水稻和非转基因水稻）中各优势杂草的危害程度明显低于空白对照；除了千金子，转基因水稻田中的优势杂草（空心菜、牛毛毡、水莎草、莲子草、水苋菜、碎米莎草、鳢肠）的危害程度均略低于对应的非转基因水稻。

| Abstract: | Weeds species and their impact in paddy fields where transgenic and non-transgenic rice was grown and in blank control fields at the plant breeding base of Hainan Province were assessed using the“five point sampling” method. There were 19 weed species of 11 families in the transgenic rice field,of which the dominant wre Ipomoea aquatica Forsk, Eleocharis yokoscensis （Franch.et Sav.） Tang et Wang,Juncellus serotinus （Rottb.） C.B.Clarke,Alternanthera sessilis （ Linn.） DC.,Ammannia baccifera L.,and Leptochloa chinensis （ L.） Nees,whose relative abundance was 38%,28%, 26%,22%,22%,and 21%,respectively.There were 17 weed species of 10 families in non-transgenic rice fields,with control.Expect for L.chinensis,the damage caused by the dominant weeds in transgenic rice fields was slightly lower than that found in non-transgenic rice fields. |
