当农民喷洒杀虫剂或其他药物时,其中只有2%能喷射在植物上,大部分往往脱离植物,落在土地上或者变成径流的一部分,导致土壤和水质污染。近日,美国麻省理工学院(MIT)的研究团队巧妙地向喷洒物中加入两种廉价的聚合物添加剂,可以大量减少反弹的液体量。许多植物叶子具有天然的疏水性,这也是它们反弹滴液的原因。而该方法利用两种不同类型的添加剂, When farmers spray insecticides or other drugs, only 2% of them can be sprayed onto plants, most of which are often detached from plants, land or become part of runoff, resulting in soil and water pollution. Recently, the research team of the Massachusetts Institute of Technology (MIT) cleverly added two inexpensive polymer additives to the sprayer to reduce the amount of liquid rebound. Many plant leaves have a natural hydrophobicity, which is why they bounce off. The method uses two different types of additives,
