Description

Technical Field

[0001] The utility model relates to the technical field of transplanting and cultivation, in particular to a cultivation device for transplanting tissue culture seedlings. Background Art

[0002] Before plant tissue culture seedlings are transplanted into the field, they need to be moved out of the tissue culture container and into a special container, where they are acclimated in a growth room or similar environment with controllable temperature, light and high humidity to adapt to a non-tissue culture environment. The commercially available container types for transplanting tissue culture seedlings are mainly divided into completely enclosed containers or containers with air holes. The first type can retain moisture but is not breathable, which can easily cause plants to mold and die. The second type can adjust the stomata for ventilation in the early stages of seedling growth, but as the seedlings grow, the air holes cannot meet the plant's ventilation needs, and the plant will be in an awkward situation where the plant will lose water and wilt if the lid is opened, and will mold if the lid is not opened. For example, the plug tray set suitable for transplanting tissue culture seedlings disclosed in the authorization announcement number CN208242336U includes a water storage tray, a plug tray, a cover, and a water level control device. The inner bottom of the water storage tray is provided with multiple support bars, and a drainage groove is provided through the outer wall of the water storage tray. The lower end surface of the drainage groove is flush with the bottom of the water storage tray, and the drainage groove is blocked by a block; after the plug tray is placed in the water storage tray, there is a gap between the plug tray and the inner wall of the water storage tray, and the lower end surface of the upper edge of the plug tray is higher than the upper end surface of the water storage tray. After the plug tray for raising seedlings is placed in the water storage tray, the support bars cause the bottom surface of the plug tray to separate from the bottom surface of the water storage tray, which is convenient for plants planted in the plug tray to absorb water. However, the size of the plug tray is limited, and seedlings with large root systems cannot be transplanted; the height is not adjustable, and there is insufficient space for large seedlings to grow; and the transparency is not enough, which affects the light, and the state of the seedlings cannot be monitored in real time under non-interference conditions, and the air permeability is not enough, which is prone to mold.
