摘　　要：[目的]筛选姜田适用除草剂及合理施用技术。[方法]采用土壤喷雾法,测定8种不同除草剂对姜的室内安全性及田间除草效果。[结果]试验剂量下,精异丙甲草胺、草酮和乙氧氟草醚对姜安全,对阔叶杂草和禾本科杂草有不同程度的防除效果,精异丙甲草胺与草酮或乙氧氟草醚混合施用,药后40 d总草鲜重防效达85%以上,姜增产效果好。[结论]精异丙甲草胺、草酮和乙氧氟草醚适用于姜田除草,可根据田间草相选择单一或混合使用。[Aims]The study aims to screen out herbicides and their precision application technology used in Zingiber officinale field for weeds control.[Methods]The selectivity in greenhouse of 8 different herbicides to Z.officinale and their efficacy in field on weeds were evaluated by soil spraying method.[Results]At test dose,S-metolachlor,oxadiazon and oxyfluorfen were safe to Z.officinale and had different degree of control effect on broadleaf and grass weeds.S-Metolachlor mixing with oxadiazon or oxyfluorfen was effective on most experimental broadleaf and grass weeds,and the 40 days total grass fresh weight control effect were more than 85%,and the yield-increasing effect is obvious.[Conclusions]S-Metolachlor,oxadiazon and oxyfluorfen are suitable for weed control in Z.officinale field,which could be used by single or mixture according to the field weed species.
