By modelling the aeration environment of agricultral irrigation in soil columns, the cultral microorganism cleaning nitrate by denitrification in aeration zone is studied. The mechanism and effects of denitrification, and the influences of environmental factors are discussed. It is further conclnded that the method of cultural microorganism treating unsaturated nitrate pollution is an effective one.
