【摘要】 运用恒温培养法研究了阿维菌素在不同土壤中的降解动力学。结果表明 ,土壤有机质、土壤温度和农药浓度对阿维菌素的降解有较大影响 ,这可能和土壤微生物有关。从试验土壤中分离到一株高效降解阿维菌素的菌株 ,经 16SrDNA鉴定为嗜麦芽寡养单胞菌 (Stenotrophomonasmaltrophilia)。土壤接种该优势菌后有助于加快阿维菌素的降解更多还原

【Abstract】 Degradation dynamics of Abamectin in different soils were studied by in cubation method. The result shows that soil organic matter, soil temperature and pesticide concentration can obvio usly affect Abamectin degradation, maybe which contributes to microorganism in soil. The dominant bacteria which can effectively degrade Abamectin was isolated from experi-mental soil, and it was identified by 16SrDNA as Stenotrophomonas maltrophilia. After the inoculation of dominant bacteria into soil Abamectin degradation was further augmented.更多还原
