中国农业大学近期研究发现,表面张力并非增强药液在植物叶片上持留和铺展能力的唯一因素。为研究不同农药剂型及表面活性剂对药液在亲水和疏水植物叶片表面的持留及铺展行为的影响,研究人员通过数码显微镜连续摄像的方法,测试了40种药液液滴在棉花(亲水性)和水稻(疏水性)叶片上的持留及铺展行为。选用5%氯虫 Recent studies by China Agricultural University have found that surface tension is not the only factor that enhances the retention and spreading capacity of liquid chemicals on plant leaves. In order to study the effects of different pesticide formulations and surfactants on the retention and spreading behavior of liquid on the surface of hydrophilic and hydrophobic plant leaves, the researchers tested the effect of 40 liquid drops on cotton Aqueous) and rice (hydrophobic) leaves on the retention and spreading behavior.
