SOIL DISINFECTION AND DISINFECTOR RODS THEREFOR

摘要

PROBLEM TO BE SOLVED: To disinfect or sterilize the soil and inhibit the propagation of microorganisms by allowing rods to stand in the soil to concentrate sun beams, introducing the beam into the soil, irradiating the photocatalyst with the beam to cause the photocatalytic reactions and sterilize the soil. SOLUTION: Rods made of a transparent material are allowed to stand in the ground soil G, the sun beams are concentrated from the part exposed to the air, the beam is introduced along the rod into the soil to irradiate the photocatalyst supported on the surface of the rod thereby sterilizing and disinfecting the soil nearby. This soil disinfector A is made of a transparent material and comprises a rod for allowing the disinfector to stand in the ground soil G and the photocatalyst that is supported on the surface of the transparent rod and disinfects and sterilize the soil by the photocatalytic reaction, when the rod is irradiated with sun beams above the ground. A plurality of the rods are inserted into the soil at an angle so that they may point its head to the sun and arranged in zigzag at a certain interval suitable for effective sterilization.
