PROBLEM TO BE SOLVED: To provide a versatile planting board member which allows intervals of plant bodies to be changed without transplanting the plant bodies.SOLUTION: A planting board member 1 has board segments 2, lateral-side mountain-fold parts 3, longitudinal-side valley-fold parts 4b, and longitudinal-side mountain-fold parts 4a, 4c. The lateral-side mountain-fold parts 3 are each interposed between the board segments 2 of a first unit and of a second unit neighboring the first unit in the lateral direction. The longitudinal-side valley-fold parts 4b are interposed between the board segments 2 arranged in the longitudinal direction in the first units. The longitudinal-side mountain-fold parts 4a, 4c are interposed between the board segments 2 arranged in the longitudinal direction. The longitudinal-side mountain-fold parts 4a, 4c are arranged neighboring the longitudinal-side valley-fold parts 4b in the lateral direction. When the lateral-side mountain-fold parts 3 are mountain-folded, the longitudinal-side mountain-fold parts 4a, 4c slide, while mountain-folded, along the lateral direction on the longitudinal-side valley-fold parts 4b that are in the valley-fold state. |
