| 摘 要： | 酿造用高粱田土壤处理除草剂种类较少，常用的除草剂配方中多数含有莠去津，筛选不含莠去津且药效较好的除草剂配方，具有较好的实践意义和现实意义。本文选取72%异丙甲草胺乳油、38%莠去津悬浮剂、25%二氯喹啉酸悬浮剂、33%二甲戊灵乳油、48%麦草畏水剂、75%噻吩磺隆水分散颗粒剂、15%硝磺草酮悬浮剂6种除草剂进行混配。通过田间试验进行安全性、除草效果及对高粱产量影响的研究。结果表明，38%莠去津悬浮剂+72%异丙甲草胺乳油、72%异丙甲草胺乳油+48%麦草畏水剂、38%莠去津悬浮剂+48%麦草畏水剂对高粱具有安全性高、除草效果好、提高产量的特点，30 d除草株总防效分别为96.5%、97.4%、93.4%,增产23.9%、23.6%和22.2%。在效益方面，莠去津+异丙甲草胺略高于异丙甲草胺+麦草畏。考虑到莠去津的长残留性及对生态的影响，建议使用72%异丙甲草胺乳油+48%麦草畏水剂。

| Abstract: | There were few kinds of herbicides for soil treatment in brew purposed sorghum field, and most commonly used herbicide formulations contain atrazine. In order to screen atrazine-free formulas, six herbicides, including metolachlor 72% EC, atrazine 38% SC, quinclorac 25% SC, pendimethalin 33% EC, dicamba 48% AS, thifensulfuron-methyl 75% WG and mesotrione 15% SC, were selected and mixed, and field experiments were carried out to investigate the safety, weed control effect and effect on sorghum yield. The results showed that atrazine 38% SC+metolachlor 72% EC, metolachlor 72% EC+dicamba 48% AS, atrazine 38% SC+dicamba 48% AS have the characteristics of high safety, good herbicidal effect and yield-increasing effect. The total plant control efficacies of 30 days weeding were 96.5%, 97.4% and 93.4%, respectively, and the yield increased by 23.9%, 23.6% and 22.2%, respectively, . In terms of benefit, atrazine 38% SC+metolachlor 72% EC was slightly higher than metolachlor 72% EC+dicamba 48% AS. Considering the long residue of atrazine and its effect on ecology, metolachlor 72% EC+dicamba 48% AS was recommended to be applied for weed control. |
