- Abstract:
-
Effects of different concentrations of pyrazosulfuron-ethyl (0.4, 4, 40 mg/kg) on fungal community structure and soil enzyme activity were investigated by PCR-DGGE and colorimetric methods. The results showed that pyrazosulfuron-ethyl can promote the activities of soil dehydrogenase and polyphenol oxide, inhibit the activity of glucanase and have no influence on fungal community structure at 7 th day At 14 th day, the activity of dehydrogenase decreased and activity of polyphenol oxide increased, and the diversity index of fungal community increased gradually with increase of pyrazosulfuron-ethyl concentration. At 21 th day, the activities of dehydrogenase and polyphenol oxide become smaller, but the activity of glucanase recover to the level of control and diversity index of fungal community structure increases gradually with increase of the pyrazosulfuron-ethyl concentration. The above results offered the data support for entirely investigating the effect of pyrazosulfuron-ethyl on soil micro-ecology environment.
