| 摘 要： | 采用实验室模拟方法研究了多菌灵在土壤生态系统中的降解动态及其对土壤微生物群落多样性的影响。结果表明,2.0和4.0 mg kg-1多菌灵在土壤中的降解半衰期分别为8.6和6.8 d。试验初期各个处理的土壤微生物群落的AWCD值显著降低,土壤微生物群落的Shannon指数、Simpson指数和McIntosh指数均低于不加多菌灵的对照,微生物群落的丰富度、均匀度和优势度受到抑制,并且多菌灵对土壤微生物的抑制作用随浓度的增加而增强。随着时间的延长,多菌灵对土壤微生物的毒性逐渐减弱,3 d后土壤微生物多样性逐渐恢复到对照水平。

| Abstract: | Degradation dynamics of carbendazim in soil and its effects on community diversity of soil microorganisms were investigated in a microcosm mimicking soil ecosystem.Half-life of carbendazim in soil was measured to be 8.6 and 6.8 d at levels of 2.0 mg kg-1 and 4.0 mg kg-1,respectively.Values of average well color development(AWCD) of soil microorganisms were significantly inhibited within the initial periods after treatments of carbendazim at levels of 2.0 mg kg-1 and 4.0 mg kg-1 soil.Meanwhile,significant re... |
