| 摘 要： | 水稻是我国最主要的粮食作物之一,杂草的危害严重影响了水稻的产量与品质。化学防除仍然是治理水稻田杂草最有效的途径。目前我国水稻田稗属杂草、千金子、马唐、雨久花、野慈姑、异型莎草、耳叶水苋、眼子菜、节节菜、萤蔺等多种杂草对二氯喹啉酸、五氟磺草胺、氰氟草酯、噁唑酰草胺、苄嘧磺隆、吡嘧磺隆、双草醚、噁草酮、乙氧氟草醚等多种常用除草剂产生了抗药性。面对日趋严重的水稻田抗药性杂草的危害,对抗药性杂草进行深入系统的研究以达到科学防治的目的显得尤为重要。本文总结了我国水稻田抗药性杂草的抗药性水平、靶标酶抗药性机理、代谢酶抗药性机理和其他抗药性机理,归纳了抗药性杂草的交互抗性、多抗性发生情况以及抗药性治理现状,分析了我们在杂草抗药性研究与治理方面面临的问题。

| Abstract: | Rice is one of the most important cereal crops in China. Weed occurrence in rice fields causes serious threats on the production and quality of rice. Currently, chemical herbicides are the main resources for weed control in rice fields. To date, more than ten weed species in rice fields in China, including Echinochloa phyllopogon, E.crusgalli var. crusgalli, E.crusgalli var. zelayensis, E.glabrescens, Leptochloa chinensis, Digitaria sanguinalis, Monochoria korsakowii, Sagittaria trifolia, Cyperus difformis, Ammannia auriculata, Potamogeton distinctus, Rotala indica and Schoenoplectus juncoides, have evolved resistance to various herbicides such as quinclorac, penoxsulam, cyhalofop-butyl, metamifop, bensulfuron-methyl, pyrazosulfuron-ethyl, bispyribac-sodium, oxadiazon and oxyfluorfen. On the background of increasing serious threats caused by herbicide-resistant weeds, in-depth and systematic researches on this topic are urgently needed. Here we summarized the resistant factors, target-site mechanisms, metabolic mechanisms and other kinds of non-target-site mechanisms in herbicide-resistant weed species. We also reviewed patterns of cross-resistance and multiple-resistance, as well as the status of management in herbicide-resistant weeds. At the end, we analyzed problems in the researches and management of herbicide resistance in China. |
