摘　　要：[目的]为探讨纤维高粱播后苗前杂草化学防除的有效方法。[方法]通过田间试验,研究了6种化学除草药剂的田间防除效果。[结果]结果表明,防除纤维高粱田一年生禾本及阔叶杂草的播后苗前土壤处理除草剂选用38%莠去津悬浮剂或330 g/L二甲戊灵乳油较适宜;在藜不是优势杂草的纤维高粱田可选用960 g/L异丙甲草胺乳油。[结论]研究结果为纤维高粱播后苗前杂草的化学防除提供了参考。[Objective]The aim was to study the effective methods of chemical control on weeds before emergence of fiber sorghum. [Method]The effect control of six kinds of herbicide in field were studied through field test. [Result]The results showed that both control annual gramineous and broadleaf could choose 38% atrazine （SC） or 330 g/L Pendimethalin （EC） which suitable for controlling annual gramineous and annual broadleaf weeds in fiber sorghum fields after sowing before emergence; 960 g/L s-metolachlor （EC） could be chosen for controlling weeds Chenopodium album L. in fiber sorghum fields, which was not dominant. [Conclusion] The result provided a reference for chemical control on weeds before emergence of fiber sorghum.
