| 摘 要： | 对露天栽培的白菜、茄子和番茄上常用有机磷和菊酯类农药的消减情况进行研究,试验结果表明,敌敌畏是一种降解速度快的农药,施药后1 d,在茄子、番茄和白菜上的降解率分别为66.67%,99%和99.9%,而毒死蜱相对降解速度慢,药后7 d在茄子、番茄和甘蓝上的降解率分别为86.47%,91.59%和97.78%。3种菊酯类农药的降解速度慢,其中以氯氰菊酯的降解速度最快。

| Abstract: | The degradation test of commonly used organophosphorus and pyrethroid insecticides in open field cultivation of Chinese cabbage,eggplant and tomato were carried out.The results indicated that the dichlorvos was a quickly degrated insecticide,on the first day after spraying pesticides the degrated rate on Chinese cabbage,eggplant and tomato was 66.67%,99% and 99.9%,the degrated rate of the chlorpyrifos was slower than the dichlorvos,on the seventh day after spraying pesticides the degrated rate on Chinese ca... |
