| 摘 要： | 按孙云沛法测定了氯嘧磺隆与咪唑乙烟酸混配的联合毒力作用，盆栽试验采用二次回归正交旋转组合设计筛选了两者混用的最佳配方。结果表明：氯嘧磺隆与咪唑乙烟酸混用具有增效作用；对禾本科杂草狗尾草1〖DK1〗∶5和1〖DK1〗∶7的配比具有增效作用；对阔叶杂草龙葵1〖DK1〗∶7配比的增效作用最大，1〖DK1〗∶10和1〖DK1〗∶17的配比也具有明显的增效作用。两者混用没有拮抗作用。并通过筛选得到了两者混用防除稗草和反枝苋的最佳配方。

| Abstract: | The combined effects of chlorimuron ethyl and imazethapyr were determined by the Sun Yunpei’s method, and the best formula were screened by using quadratic regression orthogonal rotary tests in pot experiments. It was found that the mixture of chlorimuron ethyl and imazethapyr had synergism, and the proportions 1∶5 and 1∶7 had synergism for green bristlegrass, but the proportion 1∶7 showed the strongest synergism to dragon mallow, and the proportions 1∶10 and 1∶17 had obvious synergism to dragon mallow. The mixed use of imazethapyr and chlorimuron ethyl had no antagonism. The best formula for controlling barnyardgrass and redroot amaranth was obtained in this study. |
