摘　　要：为筛选出防效好、安全性高的土壤封闭除草剂,优化土壤封闭除草技术,以8种土壤封闭除草剂为试验对象,依据《农药田间药效试验准则》,系统评估了其对小麦田杂草的土壤封闭防效。结果表明,施用35%氟噻草胺·吡氟酰草胺SC、48%吡酰·异丙隆SC、33%氟噻草胺·呋草酮·吡氟酰草胺EC和20%噻磺·乙草胺WP时封闭除草效果较好,株防效均超过85%,可显著挽回损失。此外,受持续阴雨天气影响,土壤墒情高,20%噻磺·乙草胺WP处理区内小麦产生药害症状。该结果可为小麦田杂草的科学防控和土壤封闭除草技术的普及提供参考依据。In order to screen out soil-sealed herbicides with good control efficacy and high safety and optimize soil-sealed weed control technology,this study used 8 kinds of soil-sealed herbicides as test objects,and systematically evaluated their soil-sealed control efficacy on weeds in wheat fields according to the"Guidelines for Field Efficacy Tests of Pesticides".The results showed that the pre-emergence weed control efficacy was better when flufenacet·diflufenican 35%SC,diflufenican·isoproturon 48%SC,flufenacet·flurtamone·diflufenican 33%EC and thifensulfuron·acetochlor 20%WP were applied,with plant control efficacies exceeding 85%,and had a significant efficacy in recovering losses.In addition,due to the continuous rainy weather,the soil moisture was high,and wheat in the thifensulfuron·acetochlor 20%WP treatment area showed symptoms of phytotoxicity.The results can provide a reference for the scientific prevention and control of weeds in wheat fields and the popularization of soil-sealed weed control technology.
