- 摘要:
- 选用90%乙草胺、70%嗪草酮、48%广灭灵、72%异丙甲草胺乳油（稻乐思）、48%氟乐灵乳油和50%敌草胺进行混配施用，在苗前对马铃薯田进行封闭除草试验。结果表明：不同处理组合对马铃薯田杂草均具有防除效果，同时提高了马铃薯产量，并无药害产生。其中处理1（90%乙草胺+70%嗪草酮）防除效果和增产效果最佳，对杂草的株防效达到84.47%~91.90%，鲜重防效为91.75%，增产14.57%。
- Abstract:
- Taking 90% Acetochlor,70% Metribnzin,48% Clomazone,72% Metolachlor EC，48% Trifluralin EC and 50% Napropamide as reagents,the weeds in potato field were controlled before seedling emergence with pesticide ready-mixture.The results showed that：all treatment combinations achieved control effects，increased yield and had no phytotoxicity to the potato.The control effect and increasing yield effect of treatment of 90% acetochlor and 70% metribuzin was the best among the 5 treatment combinations.Itsplant control effect was 84.47%~91.90%,fresh weght control effect was 91.75%,and it could increase the yield by 14.57%.
