The high concentration of 2000mg/kg glufosinate ammonium treatment had the most prominent effect，which decreased by 38.9 % ， 41.5% ， 40.2% ，38.4%and 37.5% on the 1st，4th，7th，10th andl3thdaysrespectively.Theeffctsofthetwoherbicidesonfungiwerequitediferent.Amongthem，glyphosate treatment hadacertaininhibitoryefectonfungi，andtheinhibitoryefectbecamemoreobviousastheconcentrationincreased;while glufosinate treatedsoil maintainedaverysignificant inhibitory effectonfungi.Glufosinate treatmentat 2000mg/kg decreased by （20 51.0% ， 53.6% ， 43.3% ， 41.0% and 38.8% respectively after1，4，7，10 and 13 days.
