Abstract:
Effect of three kinds of widely used long residual herbicides Imazethapyr，Chlorimuron-ethyl and Clomazone on the activity of soil urease in soybean farmland were researched.The results showed that there was a distinctly different effect on urease activity by the three different herbicides.Soil urease activity was significantly reduced by the three herbicides at the beginning of treatment，but with the time prolonging the urease activity of soil treated by Imazethapy was increased distinctly compare with control.The soil urease activity treated by Chlorimuron-ethyl retrieve to the normally level gradually，while that treated by Clomazone retrieve earlier than the other two herbicides and the urease activity distinctly higher than the control and remain long time.
