The reporter learned from the Hefei Institute of Material Science of the Chinese Academy of Sciences on the 5th that the scientific research personnel of the Institute of Technology and Biology of the Academy of Sciences have made new progress in the research on the prevention and control technology of wheat ear germination, using scientific and technological power to put on a nano "raincoat" for wheat.
Related achievements have been accepted and published by ACS Sustainable Chemistry & Engineering, the core journal of the American Chemical Society in the field of green chemistry.
According to reports, researchers in the research group of Wu Lifang, the Institute of Technology and Biology of the Institute, used modified natural nanomaterials as the main raw material to prepare a protective agent against wheat ear germination, which can replace chemical pesticides to prevent ear germination. This achievement is of great significance for improving wheat quality and reducing the environmental release of chemical pesticides.

As a worldwide agricultural problem, wheat ear germination not only affects yield, but also severely reduces the processing quality and plant value of wheat, thereby causing serious economic losses.
Cultivating ear sprouting resistant varieties, proper sowing and harvesting, and chemical prevention and control are common practices for preventing ear sprouting. Although chemical prevention and control can inhibit ear germination to a certain extent, it has the disadvantages of high cost, poor stability, easy to cause pollution and blindness of prevention. As people's demand for a better life and food quality grows, low-cost, non-toxic, and efficient techniques for suppressing spike germination have great market demand.
The research team prepared a hydrophobic nanomaterial by modifying the natural nanomaterial attapulgite, which can form a dense and hydrophobic structure on the surface of wheat grains, significantly inhibiting the respiration of wheat seeds and the absorption of water. This technology has the advantages of easy to use, environmentally friendly and so on, and has very good application prospects.
