烯草酮防治亚麻田杂草药效试验

摘要

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/hm2 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.%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。
