Three species of herbicides,chlortoluron,dicamba and fomesafen,were sprayed onnotillage fields of yellow-brown earth at normal and excess doses.The effects of differentherbicides at tested doses,and of chlortoluron with different tillage measure on function ofsoil ecosystems were studied.The results indicated that:according to three herbicides"s de-gree of the restraint to soil respiration,the order is dicamba>fomesafen>chlortoluron;thehigher the doses,the more the restraint.
