| 中文摘要: |
| 为了评价不同喷雾助剂对苯唑草酮减量施用下的增效作用, 采用仪器分析和田间试验的方法研究了7种助剂对30%苯唑草酮悬浮剂的药液特性和杂草防效的影响?结果表明, 7种助剂均能显著降低药液的表面张力?接触角和干燥时间, 增加药液铺展直径?其中, 杰效利对表面张力和接触角的影响最大, 迈丝和渗透者对干燥时间的影响最小?田间试验结果表明, 添加迈丝和渗透者对苯唑草酮的增效作用好于其他助剂, 苯唑草酮的田间用量可以减少30%以上? |
| 英文摘要: |
| The impact of seven adjuvants on the weed control efficacy and solution characteristics of topramezone 30% SC was investigated through the field trial and instrumental analysis to evaluate synergistic effect of adjuvants on topramezone in the dose-reduced application. The results showed that the seven different adjuvants significantly reduced the surface tension and contact angle and drying time, and expanded the diameter of topramezone droplet. Among the seven adjuvants, Jiexiaoli had the best effect on the surface tension and contact angle, while Maisi and Shentouzhe had the least effect on the drying time. Field trial demonstrated that the synergistic effects of adding Maisi and Shentouzhe on topramezone were better than other adjuvants, and the application dose of topramezone can be reduced by more than 30%. |
