PROBLEM TO BE SOLVED: To provide a cultivation net material improving adhesiveness of spores, promoting growth of the spores to ensure high yield, preventing environmental contamination and being safely and easily cleared out after an elapsed durable period of time. SOLUTION: This cultivation net material is obtained by attaching or containing a powdery iron material eluting iron ions into water to or in a resin filament. The cultivation net material is formed by twisting a plurality of pieces of single yarn obtained by mixing magnetite powder and a resin. It is preferable to twist about 5-20 pieces of the single yarn spun to have a yarn diameter of≤1mm where 20-50 wt.% of magnetite powder having≤100μm granular diameter is mixed with resin. The resin may comprise polyethylene or alternatively a biodegradable resin. COPYRIGHT: (C)2005,JPO&NCIPI
