摘要

This paper reported the biological effects of TiO_2 sol on the control of crop diseases and growth regulation. The TiO_2 sol is a neutral, viscous aqueous colloid with size of 10-50 nm and 1.6% content of TiO_2, and was synthesized from peroxotitannic acid solution by Ichinose method. XRD result showed that the crystal form of TiO_2 nano-particles was anatase. Field experiment showed the TiO_2 sol formed a well-spread, transparent, and sticky layer of TiO_2 photocatalyst on the surface of plant, which could prevent plant from pathogens infection and improve photosynthetic performance. These results indicated that the nano-TiO_2 sol can be developed as a kind of environmental-friendly crop germicide and growth regulator.
