PURPOSE: A method for manufacturing a holder of a harvest net for agriculture and fishery is provided to install a tensile spring having a high transverse elastic modulus at a certain section of the top of a pillar having the high transverse elastic modulus, thereby tightly spreading the inlet of a bag for the harvest net, or easily separating the bag full of contents from the holder. CONSTITUTION: A method for manufacturing a holder of a harvest net for agriculture and fishery includes: a step of connecting a grip (12) to outside positions of 120 mm below the tops of two pillars (20) which are mutually connected with a holding protrusion (10); a step of cutting the pillars at positions of 50 mm above the top of the grip; a step of welding both ends of tensile springs (11) which are respectively fit between the cut pillars below the holding protrusion and the cut pillars above the top of the grip; a step of connecting a base connecting member (31) to inside positions of 50 mm above the bottoms of the pillars; and a step of welding a net support (30) to inside the pillars at positions of 60 mm above the base connecting member. |
