【摘要】 通过敏感性测定 ,明确了不同水稻品种对除草剂的耐药性存在较大差异 ,结果表明 :新稻 90 2 61、豫粳 6号对杀草丹耐药性较强 ,新稻 681 1对氯嘧磺隆、扑草净耐药性较强 ,黄金晴耐药性较弱 ,田间若使用不当易产生药害。分析结果表明 ,大多数供试水稻品种种芽耐药性均大于种根更多还原

【Abstract】 Tolerance of different rice varieties to herbicides had big difference was determined through sensitiveness experiment. The results showed that XinDao 90261?YuJing 6 were drug fast tolerance to Saturn thiobencarb, Xindao 6811 was very big tolerance to Chlorimurnethyl and Cuparol Phmetryn, While HuangJinQing was weak to three herbicides. If we can not use them correct they will cause phytotoxility easily. The root of lots of varieties rice had more tolerance than shoot of rice to herbicides.更多还原
