记者从中科院合肥物质科学研究院了解到,该院技术生物所专家成功研制出一种可通过感知酸碱度来释放有效成分的控释农药,据测算能够有效提高农药利用率20%,从而减少施药频次,并且还能利用磁场回收残留农药,降低农药引发的面源污染。 Reporter learned from the Chinese Academy of Sciences, Hefei Institute of Physical Science, the Institute of Technology and Biology experts successfully developed a perceived pH to release the active ingredient of the controlled release pesticides, according to estimates can effectively improve the pesticide utilization rate of 20%, thereby reducing the application Frequency, and can also use the magnetic field recovery of residual pesticides to reduce non-point pollution caused by pesticides.
