Effect of Atrazine on Soil Phosphatase Enzyme Activity

The effect of atrazine on neutral phosphatase in paddy soil was investigated by the indoor incubator culture methods.The activity of soil phosphatase enzyme showed an inhibition-activation-inhibition rule during the experiment.The three equations had significant or obvious significant correlation between soil enzyme activity and atrazine concentration.Ecological dose ED10 of the soil phosphatase enzyme,were 19.51 mg·kg-1.
