摘　　要：采用滤纸法测定了宁夏稻田不同采集点的21份稗草种子对五氟磺草胺的敏感性。结果表明,宁夏稻田稗草种子对五氟磺草胺的抗性指数为1.00~41.06,稗草对五氟磺草胺的抗性处于中等水平抗性阶段。同时,不同采集点稗草对五氟磺草胺的敏感性表现出较大差异,同一采集点不同种类的稗草对五氟磺草胺敏感性也有差异。Filter paper method was adopted in this paper to measure barnyard grass sensitivity against Penoxsulam in Ningxia.Results showed that resistance index of barnyard grass against Penoxsulam in Ningxia ranging from 1.00 to 41.06, a mid-resistance level. Sensitivity in different sample points varied noticeably, and sensitivity difference also existed in different barnyard grass in the same sample point.
