| 摘 要： | 目的研究白蚁防治药剂毒死蜱、联苯菊酯和吡虫啉长期在野外和室内土壤的降解动态以及生物有效性。方法通过定期对野外和室内试验土壤中的药剂检测,并观察记录试验木块受白蚁危害情况,建立了白蚁防治药剂毒死蜱、联苯菊酯和吡虫啉降解动态及生物有效性的研究方法结果在野外试验地施药36个月后,毒死蜱、联苯菊酯和吡虫啉分别降解了96.76%、2.05%和97.21%;室内施药24个月后,降解率分别是90.67%、1.54%和45.48%。在野外生物有效性试验中,联苯菊酯能有效阻止白蚁的危害,试验地的木块没有受到白蚁破坏,而毒死蜱和吡虫啉的实验木块均遭受白蚁侵害。结论在土壤化学屏障中,联苯菊酯较稳定,可以有效阻止白蚁危害。 |
