%X With simulation test,this paper studied the effects of chlorimuron-ethyl and furadan on the urease activity of six meadow brown soil and black soil samples.The results showed that within the range of test concentrations,these two pesticides could activate the urease activity of test soils,with the largest increment in meadow brown soil and black soil being 46.95% and 39.36% by chlorimuron-ethyl,and 21.08% and 12.70% by furadan,respectively.Quadratic polynomial equation could better describe the relationships between the concentrations of chlorimuron-ethyl and furadan and the activity of soil urease(P<0.05).Judging from the equations for test pesticides,chlorimuron-ethyl had more significant effect than furadan.
