The present invention discloses a two-color plant cultivation apparatus. The apparatus includes a cultivation tank and a planting plate, and the cultivation tank and the planting plate are used alone, or the planting plate is covered by the cultivation tank and combined with the cultivation tank to fill the nutrient solution. Alternatively, a cavity used for storing the spray nutrient solution is formed. The two-color plant cultivation apparatus provides a dark growth environment for the root system of the plant, and makes it impossible to reproduce and grow the algae by not giving sufficient light irradiation to the algae in the nutrient solution or the spray nutrient solution. . At least one of the inner side wall of the cultivation tank, the inner bottom surface of the cultivation tank, and the lower surface of the planting plate includes at least one light-shielding layer covering the entire surface, and the method of manufacturing the light-shielding layer includes coating, injection molding, Includes crimping, bonding and spraying. ADVANTAGE OF THE INVENTION In the cultivation apparatus of this invention, the light irradiation intensity under a planting plate can be reduced to the utmost, providing a shading environment for root system growth and development, and preventing the growth and growth of algae. [Selection diagram] Fig. 1本発明は、二色植物栽培装置を開示する。当該装置は、栽培槽と定植プレートを含み、栽培槽と定植プレートは単独で使用されるか、或いは、定植プレートが栽培槽に覆設されるとともに、栽培槽と組み合わされて、養液の充填又は噴霧養液の収容に用いられる空洞を形成する。当該二色植物栽培装置は、植物の根系に暗成長環境を提供し、且つ、養液又は噴霧養液中の藻類に十分な光照射を与えないことで藻類の繁殖及び成長を不可能とする。栽培槽の内側壁、栽培槽の内底面及び定植プレートの下面のうちの少なくとも１つが、全面を被覆する少なくとも１つの遮光層を備え、当該遮光層の製造方法には、塗膜、射出成形、圧着、接着及び吹き付けが含まれる。本発明の栽培装置では、定植プレート下方の光照射強度を最大限低下させることができ、根系の成長と発育のための遮光環境を提供するとともに、藻類の繁殖と成長を防止させられる。【選択図】図１
