摘要

The profile distribution ofβ-gulcosidase activity in twelve typical paddy soil profiles with high productivity in the Taihu Lake region of China were investigated. Activities ofβ-gulcosidase in the plow layers were in the range of 52.68-137.02μg PNP g-1 soil h-1 with a mean of 89.22μg PNP g-1 soil h-1. However, most plow layers ranged from 70 to 110μg PNP g-1 soil h-1. The profile distribution of β-gulcosidase activity in the 12 soil profiles decreased rapidly with soil depth, with activity at the 60 cm depth only about 10% of that in the surface layers (0-15 cm or 0-20 cm). In these soil profiles, β-gulcosidase activity was significantly positively correlated with soil organic carbon and arylsulphatase activity.Meanwhile, a significantly negative correlation was shown betweenβ-gulcosidase activity and soil pH.
