摘　　要：[目的]明确新奥苷肽的环境化学规律,研究了其在水、土壤中的样品前处理方法,以及室内条件下新奥苷肽的水解和光解特性。[方法]室内条件下,进行了新奥苷肽在pH值4、7、9缓冲液中的水解试验,以及在水中、土壤表面的光解试验。[结果]新奥苷肽在pH值4、9的缓冲溶液中稳定性良好,在pH值7的缓冲溶液中稳定性差。(25±1)℃时新奥苷肽在p H值7条件下的水解半衰期为0.864 d;新奥苷肽在水中光解半衰期为35.5 h,在土壤表面光解半衰期为23.2 h。[结论]新奥苷肽的水解等级为易水解;在水中表现为难光解,在土壤表面表现为较难光解。[Aims] In order to study the chemical behavior of xinaomycin. The method of pretreatment in water and soil samples was studied, the photolytic and hydrolyticproperties of flumioxazin under different conditions were investigated using indoor simulation test method. [Methods] Hydrolysis test of xinaomycin in buffer solution（pH 4, 7, 9） and the photolytic test of xinaomycin in water and surface of soil were investigated under indoor condition. [Results] Xinaomycin performed good stability in buffer solution of p H 4 and 9, but not good stability in buffer solution of pH 7. The hydrolysis half-life was 0.864 d in buffer solution of pH 7 at（25±1） ℃, the photolysis half-life was 35.5 h in water and was 23.2 h on the surface of soil. [Conclusions] The hydrolytic level of xinaomycin was easy to degrade, and it was difficult to photolysis in water, and less difficult on the surface of soil.
