摘　　要：为探讨纤维高粱出苗后杂草化学防除的有效方法。通过田间试验,研究了5种化学除草药剂的田间防治效果。结果表明:防除纤维高粱田一年生阔叶杂草的苗后茎叶处理除草剂选用72%2,4-滴丁酯乳油、48%灭草松水剂或56%2甲4氯钠可溶粉剂较适宜;防除纤维高粱田一年生禾本科杂草选用50%二氯喹啉酸可湿性粉剂较适宜;同时防除一年生禾本科及阔叶杂草可选用38%莠去津悬浮剂或48%灭草松水剂+50%二氯喹啉酸可湿性粉剂。In order to study the effective methods of chemical control weeds for fiber sorghum field after seedling emergence. The control efficacy of five kinds of herbicides in field were studied through field test. The results showed that 72% 2,4-D,48% bentazone aqueous solution or 56% dimethyl 4 sodium chloride soluble powder were suitable for controlling annual broadleaf weeds in fiber sorghum fields after seedling emergence. 50% cbloroquine lin acid wettable powder was suitable for controlling annual grass weeds in fiber sorghum fields af- ter seedling emergence. 38% atrazine suspension concentrate or 48% bentazone aqueous solution added 50% chloroquine lin acid wettable powder were suitable for controlling annual grass and broadleaf.
