Description

Technical Field

[0001] The invention relates to the technical field of seed seedling cultivation, in particular to a cultivation rack for seed seedling cultivation. Background Art

[0002] Blueberry seedling cultivation is the process of growing blueberry seedlings through various techniques, primarily through cuttings, seed propagation, and tissue culture. Seed propagation is suitable for large-scale planting, but suffers from low germination rates and a long germination cycle (approximately 6-8 years). High-quality seeds must be selected and the sowing environment controlled. However, it is rarely used alone in actual production and is often combined with other methods. A cultivation rack is a device used for blueberry seedling cultivation. By adjusting the position of the seedling tray and the lighting design, the growth environment of the seedlings can be optimized. For example:

[0003] Announcement No. CN106069775A provides a seedling cultivation rack, which includes a support frame and a multi-layer placement tray. The bottom of the placement tray is provided with a slide rail and a pedal that slides along the slide rail. The pedal can extend out of the placement tray along the slide rail. The slide rail is provided with a positioning assembly for fixing the pedal; the bottom of the support frame is provided with a balancing assembly for balancing the support frame. In the present invention, the bottom of the placement tray is provided with a slide rail and a pedal that slides along the slide rail, which makes it convenient for staff to climb to the high place of the cultivation rack and to place or remove tissue culture bottles. The slide rail is provided with a positioning assembly for fixing the pedal, which can enhance the stability of the pedal; the bottom of the support frame is provided with a balancing assembly for balancing the support frame. Since the pedal needs to extend out of the placement tray, the provision of the balancing assembly can prevent the cultivation rack from tilting during climbing, thereby improving stability during climbing.

[0004] Another example is a self-watering cultivation rack for enoki mushrooms, provided in Publication No. CN112425452A. The technical problem is how to design a self-watering cultivation rack for enoki mushrooms that replaces manual water spraying on spawn bags, is relatively easy to operate, can water multiple spawn bags simultaneously, and has high work efficiency. The self-watering cultivation rack for enoki mushrooms comprises: an N-shaped plate, with four support rods fixedly attached to one side of the plate at intervals, with two support rods on each side; and five placement racks fixedly attached to the inner sides of the four support rods at intervals. The present invention places an appropriate amount of spawn bags on the placement rack, activates a drive mechanism, and the drive mechanism activates a water spray mechanism, which then atomizes water and sprays it onto the spawn bags. This eliminates the need for manual water application, making it more convenient and more efficient.

[0005] The existing technical solutions have the following defects: the existing cultivation racks are prone to cause the remaining water on the cultivation racks to flow into the next cultivation pot during cultivation and irrigation, affecting the cultivation effect. At the same time, it is inconvenient to switch the cultivation racks between shading and sun exposure at any time, affecting the production success rate of the cultivated seedlings. Therefore, the present invention provides a cultivation rack for seed seedlings to solve the above-mentioned problems. SUMMARY
