Through the soil column eluviation experiment in laboratory,the eluviation law of Atrazine in two kinds of soil and its impact factors were studied.The results showed that:When the eluviation rate was increasing from 1.8 ml/min to 4.4 ml/min,the residues of Atrazine in soil decreased,and the leaching increased respectively 10.8%(black soil),8.2%(meadow black soil);At the same time,it was beneficial for inhibiting the moving and outflow of Atrazine in the soil through increasing the content of soil organic m...
