　　为了明确土壤中氯嘧磺隆对马铃薯和甜菜生育的影响，分别在苗期和生育盛期向盆栽土壤中灌施不同浓度的氯嘧磺隆溶液，调查作物生育产量。结果表明：供试的马铃薯和甜菜苗期耐药能力弱，生育盛期耐药能力增强；马铃薯耐药能力比甜菜强。马铃薯临界浓度苗期为0.017 a.i. mg/kg 土，生育盛期约为0.071 a.i. mg/kg 土；甜菜苗期至少小于0.0002 a.i. mg/kg 土，生育盛期约为0.011 a.i. mg/kg 土。马铃薯苗期抑制产量 EC50值约为0.065 a.i. mg/kg 土，生育盛期约为0.200 a.i. mg/kg 土；甜菜苗期因植株死亡未得到数据，生育盛期约为0.014 a.i. mg/kg 土。

Various concentrations of chlorimuron-ethyl were applied in pot planted to potato and sugar beet at seedling and ful -growing stages, and the growth and yield of both crops were investigated in order to understand the effects of chlorimuron-ethyl on yields of potato and sugar beet. Chlorimuron-ethyl tolerance was weaker at seedling stage than ful -growing stage for both potato and sugar beet, and potato was more tolerant as compared with sugar beet. As for the critical concentration of potato, it was 0.017 a.i. mg/kg soil at seedling stage and 0.071 a.i. mg/kg soil at ful -growing stage. For sugar beet, it was at least 0.0002 a.i. mg/kg soil at seedling stage (no sugar beet was survived when the concentration was more than 0.0002 a.i. mg/kg soil) and 0.011 mg/kg soil at ful growing stage. EC50 for yield inhibition of potato was 0.065 a.i. mg/kg soil at seedling stage and 0.200 a.i. mg/kg soil at ful -growing stage. Because al sugar beet plants were died at seedling stage, no data of EC 50 were available for seedling stage. The value was 0.014 a.i. mg/kg soil at ful growing stage.
