摘要
为寻找棉花田草甘膦药害安全剂,用0.1%氯吡脲SL和0.004%芸苔素内酯AS各配成7个处理,蕾期按小区喷施,再用2730mg/L(有效含量)的41%草甘膦异丙胺盐SL喷施棉花,以单施草甘膦和空白为对照,结果氯吡脲和芸苔素内酯对草甘膦药害无快速明显解毒效果,但有耐毒功效。药后1个月,各处理与空白对照相比株高平均恢复力67.19%,产量平均恢复力33.33%。其中0.1%氯吡脲SL1.25mg/L(有效含量)和0.004%芸苔素内酯AS0.133mg/L(有效含量)2个处理蕾铃数在5%水平上显著而耐毒效果较好。
In order to seek for the cotton glyphosate phytotoxicity safener, matches 7 effective content processing respectively with 0.1% forchilorfenur SL and 0.004% brassins AS, the bud stage time spraying, and uses effective content 2.73 g/L glyphosate 41% SL to spraying cotton, take single application glyphosate and the blank as the comparison. The results show that the forchlorfenur and the brassins are not fast to the disintoxicating effect, but have bears the poisonous effect. A month latter, each processing and the blank comparison compare plant height average resiliency 67.19%, output average resiliency 33.33%. And 0.1% forchlorfenur SL effective content 1.25 mg/L and 0.004% brassins AS the effective content 0.133 mg/L two processing cotton bolls and buds number remarkable bears the poisonous effect at 5% levels to be good to be better.
