摘要
为探明波尔多液对2,4-D丁酯除草剂飘移对贝达葡萄伤害的缓解作用,以4年生贝达葡萄植株为试验材料,以大田2,4-D丁酯除草剂、波尔多液为试验药剂,于玉米田施用除草剂,同期,先行喷施波尔多液,然后按照玉米田施用量的30%喷施,模拟2,4-D丁酯除草剂飘移。结果表明:叶面喷施波尔多液能够有效地缓解2,4-D丁酯除草剂飘移对葡萄所造成危害,从综合效果来看,贝达葡萄的产量和品质以喷施240倍波尔多液的效果最佳,喷施220倍波尔多液效果次之;从生长状况来看,以喷施220倍液波尔多液的效果最佳,喷施240倍液波尔多液效果次之,而喷施260倍波尔多液没有达到预期效果。
In order to investigate the mitigation effect of Bordeaux mixture on 2,4-D herbicide injury of Beta grape, taking four-year Beta grape plant as test materials, and taking 2,4-D herbicide and Bordeaux mixture as test agents, in the same period of used herbicide in cornfield, first sprayed Bordeaux mixture in accordance with the amount of 30% in cornfield to analog the drift of 2,4-D buty herbicide.The results showed that spraying Bordeaux mixture on leaves could effectively alleviate the harm of the drift of 2,4-D buty herbicide to grape, from the combined effect of view, to the yield and quality of Beta grape, the effect of spraying 240 times Bordeaux mixture was the best, second was spraying 220 times Bordeaux mixture; To the growth status of Beta grape, the effect of spraying 220 times Bordeaux mixture was the best, second was spraying 240 times Bordeaux mixture, and spraying 260 times Bordeaux mixture did not achieve the desired effect.
