摘要

Quercus acutissima, soil enzymes peroxidase and invertase activities, andmineral nitrogen (NH4 -N, NO -N)+3? concentrations were measured on the 50th and 100thday under treatments of Cd (0, 15, 30 mg kg–1) with or without addition of benomyl.Results suggested enzyme activities increased with growth. A lower concentration ofCd (15 mg kg–1) stimulated peroxidase and invertase activities while a higher concentrationof Cd (30 mg kg–1) produced a negative effect on invertase. Cd increased thesoil NH4 -N+ concentration. Therefore, a lower concentration of Cd increased the NO -N 3?concentration while a higher concentration of Cd reduced theNO3 -N? concentration. Additionof benomyl had no significant effect on the two enzymes of interest and mineralnitrogen (NH4 -N and NO -N)+3? concentrations at the control check treatment (0 mg Cdkg–1).
