摘　　要：为筛选出对马铃薯田间杂草有较高防效的除草剂,连续两年开展7种除草剂对马铃薯田间杂草的药效试验。结果表明:相对于清水对照,除草剂处理和人工除草处理均能极显著的降低杂草株数、覆盖度和鲜重,极显著提高马铃薯产量;相对于人工除草,25%砜嘧磺隆水分散粒剂、15.8%精喹禾灵乳油和11%砜嘧·精喹可分散油悬浮剂能极显著降低杂草株数和鲜重,显著降低覆盖度,提高马铃薯产量。生产上建议在马铃薯田间杂草3叶期到5叶期,每667 m~2喷施25%砜嘧磺隆水分散粒剂12 g或15.8%精喹禾灵乳油120 mL或11%砜嘧·精喹可分散油悬浮剂120 mL,可有效防除马铃薯田间杂草,对马铃薯植株和后茬作物玉米安全。To identify herbicides with high efficacy for weed control in potato fields,field experiments were conducted over two consecutive years to evaluate the performance of seven herbicides.The results showed that both herbicide treatments and manual weeding treatment significantly decreased weed density,coverage,and fresh weight while markedly increasing the potato yield compared with the water control.Among the treatments,25%sulphosulfuron water dispersible granule,15.8%hydroquinone emulsifiable oil and 11%sulphosulfuron and hydroquinone dispersible oil suspension significantly outperformed manual weeding by reducing weed density and fresh weight,lowing coverage,and enhancing potato yield.It is recommended to apply 12 g of 25%sulfamysulfuron water dispersible granule,120 mL of 15.8%hydroquinone emulsifiable oil or 120 mL of 11%sulphosulfuron and hydroquinone dispersible oil suspension per 667 m 2 during the 3-leaf to 5-leaf stage of weeds.These treatments effectively control potato field weeds while ensuring safety for potato plants and subsequent corn crops.
