摘  要:
为探索安全高效的甘薯田杂草的化学防除技术,选择5种不同除草剂,通过田间小区试验探索不同施药时期、不同混用组合对甘薯田杂草的防除效果及对甘薯产量的影响。结果表明,330 g/L二甲戊灵乳油4.5 L/hm~2于甘薯栽种后土壤封闭处理45 d和108 g/L高效氟吡甲禾灵乳油0.75 L/hm~2+10%乙羧氟草醚乳油0.75 L/hm~2茎叶处理35 d对甘薯田杂草总体防治效果可达90%以上,可有效降低杂草危害,提高甘薯的产量,甘薯产量均较空白对照区增加200%以上,经济效益显著。

摘  要:
Five herbicides were selected to identify a selective and highly effective chemical control technology for weeds in sweet potato fields,and to determine the influence of application times and mixture combinations on weed control and crop yield. Overall weed control provided at 45 days after planting by pendimethalin(330 g/L emulsifiable concentrate,EC) in preemergence(4.5 L/hm~2) and by haloxyfop-r-methyl 108 g/L EC(0.75 L/hm~2) + fluoroglycofen 10% EC(0.75 L/hm~2) at 35 days after postemergence treatment was above 90%. These treatments effectively reduced the negative impact of weeds and increased sweet potatoes yield by 200% compared with the untreated areas,with a remarkable economic benefit.
