Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting equipment technology, specifically relating to a sweet potato virus-free seedling raising device. Background Technology

[0002] Cuttings and virus-free seedling propagation are the main methods for sweet potato propagation. In recent years, compared with traditional cuttings, virus-free seedling propagation has become more popular due to its high yield, fewer pests and diseases, and high survival rate. Virus-free seedling propagation mainly utilizes tissue culture technology to rapidly propagate virus-free sweet potato seedlings in culture bottles, then transplants them to seedling sheds for further propagation. Virus-free sweet potato seedlings fundamentally solve the problems of variety degeneration and yield decline caused by viral infection, resulting in higher yields, more uniform size, and more attractive shapes. For hydroponic propagation of virus-free seedlings, the most important factor is the nutrient solution supply. A suitable nutrient solution, with sufficient regular replenishment of nutrients and adequate light, allows the sweet potato seedlings to grow normally. Once they reach about ten centimeters in height, they can be propagated, and multiple propagation cycles can be performed. This results in high-generation seedlings with fewer pests and diseases and a high survival rate, which are used for seed potato cultivation, enabling high-quality planting of premium varieties and reducing risks for growers.

[0003] To ensure the germination rate of virus-free sweet potato seeds, nutrient solution needs to be placed in the seedling tray during hydroponic propagation. Sponges are placed in the nutrient solution, and the sweet potato seedlings absorb the nutrient solution through the sponges. These virus-free seedlings need to be given sufficient nutrition and light regularly during hydroponic propagation, which places higher demands on the seedling device. Existing seedling devices occupy a large area, and the location and range of light that can be received each day are fixed. Therefore, a sweet potato seedling device that can be replenished with nutrients regularly, has high planting efficiency, and can provide sufficient light is needed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a sweet potato virus-free seedling raising device with a simple structure and small footprint. Nutrient solution can be added to the sweet potato seedlings through an electromagnetic valve and a booster pump, providing sufficient nutrition for the seedlings. The planting box can be rotated through a rotary drive device to ensure that the sweet potato seedlings receive sufficient light at different times. Furthermore, the planting boxes can be stacked according to the planting situation, making the planting device more flexible and versatile.
