摘要 近年来,随着水稻直播方式在辽宁滨海稻区的推广,为解决新的农田杂草防治问题。本研究通过选用4种除草剂进行田间主要杂草株防除试验。试验结果表明,460 g/L二甲·灭草松SL对除稗草外杂草防治效果最好,50%二氯喹啉酸WP对稗草防效最好,25 g/L五氟磺草胺OD和19%氟酮磺草胺SC杀草范围最广,25 g/L五氟磺草胺OD对稗草具有较好的防治效果,19%氟酮磺草胺SC对雨久花(Monochoria korsakowii)和野慈姑(Sagittaria trifolia)的防效最好。19%氟酮磺草胺SC、25 g/L五氟磺草胺OD和50%二氯喹啉酸WP前期均对水稻分蘖有一定的抑制作用,施药28 d后抑制解除,对株高无影响;460 g/L二甲·灭草松SL处理对株高和分蘖均无影响。 Recently years,the new farmland weed problem arises with the direct seeded paddy field promoted in the coastal rice area of Liaoning.The studied selected of 4 herbicides were used to control the main weeds in the field.The results showed that 460 g/L 2methyl 4chlorite.herb pine SL had the highest control effect on weeds except E.crusgalli,50%quinclorac WP had the best control effect on E.crusgalli,25 g/L Penoxsulam OD and 19%fluoxsulam SC have the widest range of killed weeds.25 g/L Penoxsulam OD has a good control effect on E.crusgalli,and 19%fluoxsulam SC had best control effect on M.korsakowii and S.trifolia.19%Fluoxsulam SC,25 g/L Penoxsulam OD and 50%quinclorac WP had an inhibitory effect on rice tillers in the early stage.The inhibition was lifted after 28 days of application and had no effect on plant height;460 g/L 2methyl 4chlorite.herb pine SL neither height nor tiller had any effect.
