PROBLEM TO BE SOLVED To obtain a soil cleaning material for plant phytopathogen such as Fusarium in soil to non-agricultural chemicals as needed to the depth of contaminated soil as needed.SOLUTION: The present invention is carried out in two stages. Initially symmetric contaminated soil is heated to a predetermined temperature using a conductive heating element and maintained at that temperature. Next, it was confirmed that mixing of the antimicrobial fine particles of silver or copper into the solution, and attaching and holding this solution to insoluble porous particles whose particle size was adjusted, and coating the antibacterial fine particles or the porous particles on the water permeable nonwoven fabric Protected soil cleaned using characteristic soil cleaning materials.(FIG.【課題】本発明は土壌中のフサリウムなどの植物病原菌を無農薬で随時に必要な汚染土壌の深さまでおこなう土壌清浄化材を得ることである。【解決手段】本発明は二段階で行う。初めに対称の汚染土壌を電導発熱体を用いて所定温度まで加熱しその温度を維持する。次に、銀または銅の抗菌性微粒子を溶液に混合し、この溶液を粒度調整した不溶性多孔質粒子に付着担持して、この抗菌性微粒子又は多孔質粒子を透水性不織布に塗着したことを特徴とする土壌清浄化材を用いて浄化済土壌を防護する。【選択図】 図3
