摘　　要：亚麻为平播密植作物,杂草发生较重,杂草防治效果直接影响亚麻的产、质量。2012年我们完成了24%烯草酮防治亚麻田禾本科杂草药效试验。田间试验结果表明:24%烯草酮乳油450—600 ml/hm2对禾本科杂草有较好的防除效果,亚麻原茎、种子、纤维均比空白对照增产35.77%-45.76%、21.82%-28.20%、47.72%-50.65%;烯草酮对狗尾草、马唐、野黍、碱草等抗性杂草有特效,在一定范围内使用对亚麻安全。Flax is planted flatly in high density, the weeds in the fields happen seriously. Flax yield and quality are directly concerned with the effect of weeds preventing and controlling. In this paper 24% clethodim EC was used to test the weeding efficiency, the results showed that 24%, 450 -600 mL/hm： clethodim EC had good prevention to the gramineous weeds. The yields of flax stems, seeds and fibers in- creased by 35.77% -45.76%, 21.82% -28.20% and 47.72% -50. 65% respectively over the CK. Clethodim could also control the green Foxtail, common Crabgrass, Eriochloa villosa and Alkaligrass. It was safe for flax used with a certain dosage.
