摘要：
The disclosure discloses a bicolored plant cultivation apparatus. It contains two parts: a cultivation tank and a planting plate which can be assembled as a cavity for storing nutrient solutions and nutrient aerosols, or both can be used separately. In order to create a dark environment inside the cavity, the surface of inner bottom and lateral walls of the cultivation tank, the lower surface of the planting plate, or at least one of them will be coated with one layer of light blocking material. The principle behind the disclosure is to minimize the light intensity below the planting plate in order to provide a low light environment which is suitable for plant root growth and inhibits the alga growth at the same time. The preparation methods of the light-blocking layer include coating, injection moulding, lamination, adhesion and spraying.
