PURPOSE:To enable the nutriculture of plants even outdoors by aligning many concrete U-shaped grooves in a moderately inclined state, spreading a plastic sheet on the insides of the aligned grooves, and subsequently forming the way of a culture solution with plastic flashboards in a stepped flow state. CONSTITUTION:Many concrete U-shaped grooves 1 are aligned in a moderately inclined state, and a water-impermeable plastic inner lining sheet 2 is spread over the whole inner surfaces of the aligned U-shaped grooves. Overflow flashboards 8 are fixed with damming hooks 6 and flashboard presses 9 to form a stepped waterway. The formed waterway is covered with a concrete lid having holes for culturing plants to protect the plants from sun light and strong wind.
