| 摘 要： | 对3种苗后化学除草剂与莠去津、莠去津和2,4-D丁酯混用进行了田间药效试验研究。结果表明:烟嘧磺隆、硝磺草酮、唑嘧磺草胺等3种除草剂和莠去津或莠去津和2,4-D丁酯进行二元或三元复配,对玉米田杂草均有很好的防治效果。二元复配施药后45 d防治效果分别为92.20%、93.30%和92.36%。三元复配施药后45d防治效果分别为96.43%、96.16%和94.29%。通过二元或三元复配,既扩大了杀草谱,又提高了防治效果且对玉米生长安全,与人工除草相比,增产6%以上。

| Abstract: | Experiment on the effect of controlling weeds with mixture of three herbicides of post-emergence with atrazine or atrazine with 2,4-D butylate was carried out in the field.The results showed that three herbicides of nicosulfuron,mesotrione and flumetslam mixed with atrazine or atrazine with 2,4-D butylate controlled weeds very well.The effect of controlling weeds with mixture of two kinds of herbicides was 92.20%,93.30% and 92.36%.The effect of controlling weeds with mixture of three kinds of herbicides was... |
