摘　　要：为获得适宜绿豆和红小豆种子萌发的最佳药剂和浓度,采用室内培养皿发芽试验研究了40%啶虫脒可溶性粉剂、25%噻虫嗪水分散粒剂、10%虫螨腈悬浮剂、20%氯虫苯甲酰胺悬浮剂和30%唑虫酰胺悬浮剂5种内吸性杀虫剂对小宗作物绿豆和红小豆种子萌发的影响。结果表明:10%虫螨腈悬浮剂和20%氯虫苯甲酰胺悬浮剂适合绿豆种子萌发,且浓度分别为120.0、12.0 mg/L时绿豆种子的发芽率、发芽势和发芽指数均最佳;除10%虫螨腈悬浮剂不适合红小豆种子萌发外,其他4种被测内吸性杀虫剂均适合其种子萌发,尤其是25%噻虫嗪水分散粒剂和30%唑虫酰胺悬浮剂,浓度分别为87.5、120.0 mg/L时红小豆种子的发芽率、发芽势和发芽指数均最佳。因此,建议使用10%虫螨腈悬浮剂和20%氯虫苯甲酰胺悬浮剂处理绿豆种子时浓度分别设定为120.0、12.0 mg/L;25%噻虫嗪水分散粒剂和30%唑虫酰胺悬浮剂处理红小豆种子时浓度分别设定为87.5、120.0 mg/L。In order to This study aims to obtain the optimum agents and the optimum concentration on seeds germination of mungbeans and adzuki beans,an experiment was carried out to determine the effects of acetamiprid 40%water soluble powder,thiamethoxam 25%water dispersible granule,chlorfenapyr 10%suspension concentrate,chlorantraniliprole 20%suspension concentrate and tolfenpyrad 30%suspension concentrateon seed germination of mungbeans and adzuki beans by using an indoor culture dish method.The results showed that chlorfenapyr 10%suspension concentrate of 120.0 mg/L and chlorantraniliprole 20%suspension concentrate of 12.0 mg/L made mungbeans have the best germination rate,germination potential and germination index,respectively.However,the adzuki bean seeds germination would be inhibited by chlorfenapyr 10%suspension concentrate at all tested concentrations.Fortunately,the other four tested insecticides were suitable for adzuki bean seeds germination.Especially,thiamethoxam 25%water dispersible granule at 87.5 mg/L and tolfenpyrad 30%suspension concentrate was at 120.0 mg/L made the adzuki beans have the best germination rate,germination potential and germination index,respectively.We suggested that chlorfenapyr 10%suspension concentrate at 120.0 mg/L and chlorantraniliprole 20%suspension concentrate at 12.0 mg/L are good for mungbeans,thiamethoxam 25%water dispersible granule at 87.5 mg/L and tolfenpyrad 30%suspension concentrate at 120.0 mg/L are good for adzuki beans.
