草甘膦飘移到敏感作物大豆田,会造成对大豆的伤害和产量降低。为解决这一生产实际问题,对飘移控制剂控制草甘膦飘移及除草效果的影响进行了研究。结果表明:飘移控制剂不改变草甘膦的除草效果,可显著减小草甘膦的顺风飘移距离,降低草甘膦飘移对大豆株高、地上部及根系干重和叶片叶绿素含量的毒害。在风速为4m/s时,顺风12m及以上距离,飘移控制剂可控制草甘膦不造成对大豆的危害。
Glyphosate drift to the sensitive crop soybean fields, will cause damage to soybeans and reduce production. In order to solve this practical problem of production, the effect of drift control agent on the control of glyphosate drift and herbicidal effect was studied. The results show that the drift control agent does not change the herbicidal effect of glyphosate, and can significantly reduce the windward drifting distance of glyphosate and reduce the toxicity of glyphosate drift on plant height, shoot dry weight and root chlorophyll content. In the wind speed of 4m / s, downwind 12m and above, drift control agent can control glyphosate does not cause harm to soybeans.
