In 2017, the nano efficient agriculture team first proposed the application of metal nano powder in agriculture, and put forward the new concept of "nano efficient agriculture". Up to now, we have carried out trials and demonstration of staple crops, fruits and vegetables, forages and Chinese herbal medicines in 23 provinces, cities and autonomous regions, including Gansu, Xinjiang, Henan, Ningxia, Inner Mongolia, Sichuan, Hainan, Heilongjiang, Jilin, Hunan, Hebei and Tianjin, with a total area of more than 15000 mu. We achieved remarkable results in increasing production and increasing efficiency, improving crop quality, and improving the quality of crops. It can enhance the ability of disease resistance and natural disasters, effectively reduce the use of chemical fertilizers and pesticides, and improve the soil. More than four years of experimental demonstration results show that: single nano iron seed treatment or single nano iron foliar spray can increase the yield of crops. The seed soaking treatment was better than seed dressing treatment, Two times of foliar spraying could increase the yield by 8-18.5%. Nano iron seed treatment plus foliar spray treatment can increase yield by 24-42%.

At the second plenary session of the China Russia science and technology alliance, our company plans to introduce the results of the experiment and demonstration of high-efficiency nano agriculture to Russia, hoping to cooperate in the experiment and demonstration of different crops in Russia.
