Abstract

See full text

The invention discloses a photocatalytic foliar fertilization method, relating to agriculture technology. To be specific, the solution containing photocatalysts and polyols is sprayed on the leaves of crops to provide nitrogen fertilizer under sunlight; the photocatalysts are nanocatalysts responding to the sunlight spectrum, of which the conduction band position is lower than −0.092 V(vs NHE); the mass concentration of photocatalysts in the solution is 100˜2000 mg/L, and the volume fraction of polyols accounts for 1%˜20%. In the invention, with the introduction of hole sacrificial agents to constrain the annihilation of photogenerated carriers, the electrons can be generated over the catalysts under sunlight and then react with dinitrogen to form ammonia as nitrogen fertilizer on the leaves of crops. This method has no demand for extra supplementation of nitrogenous fertilizer. Besides, it improves the utilization rate of nitrogen with a simple, secure and convenient fertilization.
