  • 摘要: 采用室内模拟试验方法,研究了苯噻菌酯在东北黑土、江西红壤和南京黄棕壤中的降解、吸附和迁移特性.结果表明,苯噻菌酯在3种不同土壤中的降解顺序为东北黑土> 南京黄棕壤> 江西红壤,半衰期分别为 32.8、37.9、51.7 d,属于中等降解农药.随着土壤含水量(20%—80%)增加,苯噻菌酯的降解速率加快.苯噻菌酯在灭菌土壤中降解速率明显减慢,渍水条件下降解速率加快,说明土壤中微生物,特别是厌氧微生物是影响苯噻菌酯降解的重要因素.此外,土壤中有机质和氧化物能促进苯噻菌酯的降解.3 种土壤对苯噻菌酯的吸附均较好地符合Freundich方程,吸附系数Kd值分别为 171.33、102.41和135.89,属于较易吸附农药.苯噻菌酯在土壤中移动性较差,属于难淋溶农药.
    Abstract: Degradation, adsorption and leaching behavior of benzothiostrobin in black soil of Northeast China, red soil of Jiangxi and yellow-brown soil of Nanjing were studied by using indoor simulation test method. The results showed that the degradation rates of benzothiostrobin in three soils followed the order of black soil of Northeast > yellow-brown soil of Nanjing > red soil of Jiangxi. The half lives were 32.8, 37.9 and 51.7 days, respectively, suggesting benzothiostrobin belongs to medium degradation pesticides. The degradation rate of benzothiostrobin was accelerated with increasing soil moisture (20%—80%). The rate was decreased significantly in sterilized soil, but it was accelerated in anaerobic condition. These results indicated that microbials in soil, especially anaerobic microorganisms are an important factor affecting the degradation of benzothiostrobin. In addition, the organic matters and the oxides in soil could promote the degradation of benzothiostrobin. The adsorptions of benzothiostrobin fit Freundich equation in three soils, and Kd values were 171.33, 102.41 and 135.89, respectively, suggesting benzothiostrobin belongs to easy adsorption pesticides. Benzothiostrobin had poor mobility in soil, is therefore different to leach out.
