摘　　要：着重探讨苯达松、草甘膦在苜蓿种子地的化学除莠作用。通过对两种农药的适用浓度和喷施期的研究表明，苯达松对防除苜蓿种子地杂草——田旋花、灰绿藜、艹扁蓄、地肤等有较好效果，在杂草幼苗期，０．５％浓度即可达到防除目的，且对苜蓿影响不大，值得推广；草甘膦是灭生性农药，不宜在苜蓿地中喷施，但在苜蓿地头田边喷施有较好效果，０．The effects of herbicides bentazon and glyphosate on weeds in lucerne seed producing field were observed and compared.It was shown that bentazon solution of 5% concentration was effective in killing several common weeds in lucerne field,without damaging lucerne.Glyphosate,on the other hand,could kill lucerne plants as well,and hence was suggested to be used only for weed control in peripheral areas.
