| 中文摘要: |
| 采用盆栽法茎叶处理方式分别测定了黑龙江省五常市志广乡长富村（种群H-1）、兴凯湖农场一连队（种群H-2）、八五四农场现代农业研发中心（种群H-3）、鹤岗市江滨农场（种群H-4）、庆安县久胜镇久旺村（种群H-5）共5个地区水稻田野慈姑对吡嘧磺隆的ED50值。结果表明，不同种群对吡嘧磺隆的敏感性不同，敏感程度依次为：种群H-1>种群H-2>种群H-3>种群H-4>种群H-5，其ED50值(以有效成分计)分别为107.04、163.92、289.61、320.50、484.06 g /hm2。各种群对吡嘧磺隆的ED50值与其使用年限呈正相关，吡嘧磺隆使用年限越长的地区，野慈姑的ED50值越大；且各种群对吡嘧磺隆的ED50值是20世纪90年代初期黑龙江省水稻田吡嘧磺隆常规田间施药量(以有效成分计)10～15 g/hm2的10.7～48.4倍。 |

| In order to evaluate the sensitivity of Sagittaria trifolia Linn. from Heilongjiang Province to pyrazosulfuron ethyl,the corms of S.trifolia were collected from paddy fields in Wuchang City（Population H-1）, Xingkaihu Farm（Population H-2）, 854 Farm（Population H-3）,Jiangbin Farm（Population H-4） and Qing’an County（Population H-5） in Heilongjiang Province, and pot experiments and foliage treatment were conducted to determine the ED50. The ED50 values(active ingredients) of different populations were 107.04 g/hm2, 163.92 g/hm2, 289.61 g/hm2, 320.50 g/hm2 and 484.06 g/hm2, respectively, and different populations had different sensitivities to pyrazosulfuron ethyl in the following order: Population H-1> Population H-2> Population H-3> Population H-4 > Population H-5. The ED50 values of different populations had positive correlation with the treatment time of pyrazosulfuron ethyl.The ED50 values of different populations were 10.7-48.4 times as those in paddy fields of Heilongjiang Province in the early 1990 s. |
