本试验所用不同药剂对麦田杂草封闭处理,对小麦出苗均影响,表现安全。不同药剂对麦田杂草进行封闭处理后,残留草量、鲜重、实产与对照间均有极显著差异说明参试药剂对杂草均有抑制效果。试验结果表明:对于禾本科杂草,33%氟噻·吡酰·呋悬浮剂拜宝玛防效最好;其次是有效成分含量45%微胶囊悬浮剂二甲戊灵(田普);第三是每亩使用250g的异丙隆;每亩喷施140g的绿麦·异丙隆,噻磺·乙草胺封闭效果欠佳。对于阔叶杂草,有效成分含量45%微胶囊悬浮剂二甲戊灵(田普)防效最好;其次是33%氟噻·吡酰·呋悬浮剂拜宝玛;第三是每亩喷施140g的绿麦·异丙隆和每亩使用250g的异丙隆;每亩喷施140g的噻磺·乙草胺封闭效果欠佳。
The different agents used in this experiment closed the weeds in wheat field and affected the emergence of wheat and showed safety. After the different medicaments were closed to the weed in the wheat field, the residual grass weight, fresh weight, and the actual production and the control showed extremely significant differences, indicating that the tested medicaments all had the inhibitory effect on the weeds. The results showed that the control effect of 33% fluticasone furoate was the best, followed by the 45% microcapsule suspension pendimethalin (TAP) The third is the use of 250g per acre of isoproturon; spraying 140g per acre of green wheat isoproturon, thiazole acetochlor blocking effect is poor. For the broad-leaved weeds, 45% effective content of the microcapsule suspension Pendimethalin (Tian Pu) control effect is best; followed by 33% fluronyl · fluronyl · furosemide suspension Baibaoma; the third is per acre Spraying 140g of green and isoproturon and using 250g of isoproturon per mu; spraying 140g of thiazole and acetochlor blocking poor results.
