| 摘 要： | 通过采用盆栽喷雾法对几种玉米苗后化学除草剂杀草谱及田间药效试验,结果表明:烟嘧磺隆、2,4-D丁酯、莠去津杀草谱有较大差异,烟嘧磺隆与2,4-D丁酯混用、烟嘧磺隆与莠去津混用可以弥补各自杀草谱的不足,具有一定混用价值。通过田间药效试验,4%烟嘧磺隆悬乳剂50 mL/667m2+72%2,4-D丁酯乳油25 mL/667m2、4%烟嘧磺隆悬乳剂75 mL/667m2+72%2,4-D丁酯乳油30 mL/667m2、4%烟嘧磺隆悬乳剂50mL/667m2+38%莠去津悬乳剂100 mL/667m2、4%烟嘧磺隆悬乳剂75mL/667m2+38%莠去津悬乳剂150mL/667m2,药后30d对禾本科杂草株防治效果分别为94.06%、97.83%、94.84%和98.12%;对阔叶杂草株防治效果分别为92.49%、97.35%、92.62%和97.20%。

| Abstract: | Experiment on control spectrum of several herbicides of post-emergence of corn was car-ried out in pot-cultured and in open field..The results showed that the weed control spectrum of nicosul-furon,2,4-D butylate and atrazine are different.Therefore,the mixture of nicosulfuron+2,4-D butylate,nicosulfuron+atrazine can enlarge the range of weeds controlling.Field experiment was conducted to fur-ther evaluate joint action of nicosulfuron+2,4-D butylate,nicosulfuron+atrazine.The results showed that the control ... |
