摘　　要：室内土壤滴浇法测定了苯磺隆、苄嘧磺隆对不同小麦品种的安全性和叶绿素含量的变化,结果表明:两种药剂对不同小麦品种的安全性存在较大差异,且对根长的抑制作用明显大于株高;对叶绿素含量的影响与对株高的影响结果一致。苯磺隆对周麦13的根和芽敏感,使用不当易产生药害;对偃师4110根长最安全,株高最敏感。苄嘧磺隆对高优503根长最安全,株高最敏感;对周麦13株高最安全,根长最敏感。因此,小麦田化学除草应根据不同小麦品种来选择除草剂品种、有效用量和最佳施药方法。Method of indoor soil dropping is used to study the safety of Tribenuron-methyl and Bensulfuron-methyl on different wheat strains and the change of the content of chlorophyll. It is showed that there exists big difference between the safeties of the two to different wheat strains and their inhibition to the length of root is greater than to the height of plant. Their impact to the content of chlorophyll is relative to their impact to the height of plant. Zhoumai 13 is sensitive to tribenuron-methyl and improper usage may cause damage. Yanshi 4110＇s height of root is the safest to tribenuron-methyl and its height of plant is the most sensitive to it. Gaoyou 503＇s length of root is the safest to bensulfuron-methyl and its height of plant is the most sensitive to it. Zhoumai 13＇s height of plant is the safest to bensulfuron-methyl and its length of root is the most sensitive to it. Thus, proper herbicide, virtual dose and best method should be adopted according to the different wheat strain.
