| Abstract: | The effect of three kinds of long residual herbicides,Imazethapyr,Chlorimuron-ethyl and Clomazone,which were widely used in soybean farmland,on activity of soil cellulase was studied.The results showed that the soil cellulase activity was significantly elevated by the three herbicides significantly in 7 days after application,and it retrieved to the normally level gradually in 35~42 days after application. |
