摘要：
PROBLEM TO BE SOLVED: To provide a plantation plate which can improve strength and weather resistance while suppressing weight increase, and which can control contamination and reduce the cultivation cost of crops.SOLUTION: A plantation plate 1 which is used in floating situation on a nutrient solution S within a water tank T in hydroponics, has a plurality of planting holes H penetrating toward the thickness direction, and holds a seedling P of the crop in the planting hole H to cultivate crops with the nutrient solution S is configured with a substrate 2 which is a foaming-synthetic-resin plastic body and a plastic paint film 3 which covers the substrate 2 and is a paint film of a solventless type plastic paint. Since the surface of the substrate 2 of a foaming-synthetic-resin plastic body which is lightweight is covered with the plastic paint film body 3, strength and weather resistance are improved while suppressing weight increase. In addition, since the roots of algae and crops, and the like do not encroach into the fine gaps of the substrate 2 which is a foaming-synthetic-resin plastic body, contamination of the planting plate 1 can be suppressed.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】重量の増加を抑えながら、強度及び耐候性を向上できるとともに汚染を抑制でき、作物の栽培コストを低減できる定植板を提供する。【解決手段】水耕栽培において水槽T内の養液Sに浮かべた状態で使用され、厚み方向に貫通する複数の定植孔Hを有し、定植孔H内に作物の苗Pを保持して養液Sにより作物の育成を行う定植板1を、発泡合成樹脂成形体である基体2、及び、基体2の表面を被う、無溶剤タイプの樹脂塗料の塗膜である樹脂塗膜体3により構成した。軽量である発泡合成樹脂成形体である基体2の表面を樹脂塗膜体3により被っているので、重量の増加を抑えながら強度及び耐候性が向上する。その上、発泡合成樹脂成形体である基体2の微細な間隙に藻や作物の根などが食い込まないことから、定植板1の汚染を抑制できる。【選択図】図1
