Effect of carbendazim on bacterial community diversity of grey desert soil in Xinjiang
摘要
Abstract
The aim is to explor the effect of carbendazim on bacterial community diversity of grey desert soil,and to provide the scientific basis for the safe handing of carbendazim in Xinjiang. Using the PCR - DGGE method,the effects of carbendazim at different concentrations (0,5,10,20,50 mg/kg and 100 mg/kg dry soil) on bacterial community di-versity of grey desert soil in Xinjiang were studied. Under experimental conditions,the variety and structure of bacterial community were changed by adding carbendazim in soil. With carbendazim concentration increasing,the Shannon-Wiener index and abundance index were increased at 14th day,but decreased by 4.05% ~ 29.48% and 9.01% ~ 63.64% respectively at 28th and by 6.13% ~ 16.86% and 22.22% ~ 38.89% respectively at 42nd day. . Treatments with carbendazim had little effects on evenness and Simpson index of soil bacteria. According to comprehensive analysis,the application of carbendazim affected the types and structures of soil bacteria,and changed the diversity of population and structure of soil bacteria,which led to the bacterial community diversity decreasing.关键词
