The application discloses a kind of detection methods of
inositol hexakisphosphate and its application in
plant cultivation, the application utilizes the electrostatic and
chelation of nano
iron oxide and
inositol hexakisphosphate Induce
nanoparticle aggregation, cause color change or UV-Vis absorption
peak shift (200~220 nm), for the
rapid detection of
inositol hexakisphosphate concentration in soil or
nutrient solution,
detection limit 0.1 mg / L, total time <10 minutes.The method includes
sample extraction, reaction and optical determination steps, suitable for on-
site monitoring of
phosphorus fixation and
fertilizer quality control.The detection results of the application can guide the application of complex, improve the
phosphorus utilization efficiency by 20~30%, and enhance the
plant cultivation effect (such as alfalfa yield increase by 18%,
rice growth period is shortened by about 7 days).The method of the application is suitable for
soil phosphorus fixation monitoring.
