- 摘要:
- 为了建立刺五加(Acanthopanax senticosus)化学除草技术体系,针对黑龙江省刺五加人工栽培中苗期杂草防控难题,系统评价了5种除草剂的安全性和防效。结果表明,48%仲丁灵乳油(3 000 g·hm-2)与84%双氯磺草胺水分散粒剂(45 g·hm-2)处理组表现出优良性能,保苗率分别达34.00%和38.67%,鲜质量(19.20和22.55 g)及株高(29.12 和30.47 cm)接近人工除草水平。34%氧氟·甲戊灵乳油(1 500 g·hm-2)虽总草株数防效达94.3%,但保苗率仅4.00%,存在严重药害风险。仲丁灵乳油对刺五加田禾本科杂草防效突出,但对阔叶杂草防效较弱;双氯磺草胺水分散粒剂对阔叶杂草防效更优。
