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 lchinose 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.
