摘　　要：为筛选对冬季亚麻苗期安全、高效、低成本的除草药剂,本研究比较了不同化学除草剂及其不同用量对亚麻田间杂草的防除效果,并以人工除草和不除草方法为对照,对比分析不同除草方法的投入和产出情况。结果表明,90%异丙甲草胺乳油2250 ml/hm2处理对冬季亚麻田杂草的防除效果较好,对亚麻生长安全,能显著降低劳动力和生产成本投入,提高亚麻种植效益,可以作为冬季亚麻田芽前化学除草方法推广应用。In order to screen out a safe, high efficiency and low cost weed control herbicides used in winter flax field at sprouting stage, this paper compared different chemical herbicides and dosages on the weed control effect in flax field. At the same time, using artificial weeding and non - weeding methods as control, we analyzed the input and output of different weed control methods. The results showed when 2250 ml 90% metolachlor emulsifiable was used per hectare, the weed control effect was better compared to the other treatments. It was also safe for flax growth and can significantly reduce the labor and production costs and improve the efficiency of flax cultivation. Therefore, it can be further extended to control weeds in winter flax field at pre -sprouting stage.
