Abstract: 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.

Abstract: The present invention provides a nursery block, including a nutritive block for providing nutrients to seeds. The top of the nutritive block is provided with a seed placement pit. The seed placement pit is internally provided with a seed cultivation pit. The seed placement pit is of a structure with a big top and a small bottom so that the seeds fall into the seed cultivation pit along the surface of the seed placement pit under the action of gravity. The seed cultivation pit is internally provided with a notch which extends in a direction away from the seed cultivation pit and provides growth paths for root systems of the seeds. The present invention can improve the sowing efficiency, stabilize and moisten seeds and improve the overall germination rate and germination uniformity of the seeds, and is convenient for mechanized sowing.

Abstract: Disclosed a hole plate rack capable of adjusting a distance between a plant root system and a nutrient solution level. Height adjustment structures are added on both sides of the hole plate rack to adjust the distance between a seedling root system and the nutrient solution level. The height adjustment structures are designed on both sides of the hole plate rack, and include grooves dug in both sides of the hole plate rack, and height cushion blocks. Inner walls of the grooves are provided with height cushion block separators. The height cushion blocks are rotatably connected into mounting holes in the inner walls of the grooves through plug pins, and are rotated to different positions to realize height adjustment.
