Publication number: 20200189989Abstract: An application of syringic acid in promoting the inhibition effect of decanediol on the nitrosification activity of nitrosomonas is provided. By inhibiting the activity of a nitrosomonas, the combined use of syringic acid and 1,9-decanediol can more efficiently inhibit a nitrification process in soil and at the plant rhizosphere, increase the nitrogen use efficiency, and reduce leaching of nitrate nitrogen, thereby reducing the loss of nitrogen and discharge of the greenhouse gas nitrous oxide in a denitrification process. The addition of syringic acid in the present invention can reduce the concentration at which 1,9-decanediol functions under the equivalent condition of nitrification inhibition activity, and thus save the relative input cost.Type: ApplicationFiled: May 15, 2019Publication date: June 18, 2020Inventors: Weiming Shi, Xiaonan Zhang, Yufang Lu
