摘要
从多年施用阿特拉津的栽参土壤中分离出3株放线菌，对其在可控条件下在土壤中降解阿特拉津的效果进行了研究。结果表明：土壤中阿特拉津生物降解过程符合一级反应动力学关系c=coe^k·t，拟合曲线的相关指数为0．81．0．99。在土著微生物的作用下，阿特拉津的降解半衰期为26．6—28．4d，土壤中接入放线菌后，降解半衰期为2—20d。
Three strains of actinomyces were isolated from Panax planting soil that applied Atrazine for years. Their effect on degradation of Atrazine was studied under the control conditions. The result showed that the procession of Atrazine degradation in soil fitted the first order reaction kinetics model c = c0e^-k·t the correlation index was 0.81 -0.99. Under the effect of aboriginal microorganism, the half life of actinomyces was 26.6 - 28.4 d, while the half life was 2 - 20 d after the actinomyces were inoculated in soil.
