摘　　要：利用土柱模拟农田污灌下的包气带环境，对人工微生物在包气带中反硝化作用除氮进行了研究。并讨论了脱氮机理。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.
