The invention relates to the field of cultivation and planting equipment, and discloses a
seedling raising device for planting
rhododendron simsii, which comprises a synchronous traction mechanism positioned on a main
portal frame, and a screw rod component matched with the main
portal frame is used for generating traction force for synchronous inclination of a cultivation structure; the cultivation bearing mechanism is positioned on the longitudinal cross beam, and is matched with the traction sleeve seat and an output bent
pipe of the overhead drainage box to bear and cultivate rhododendron seedlings; the light supplementing longitudinal mechanism is located on the main
portal frame and used for generating specific-angle illumination needed by cultivation. Through linkage of the mechanisms, flow channels of all cultivation bearing mechanisms are automatically connected into a continuous zigzag pipeline, it is ensured that cultivation liquid can uniformly flow through each layer, absorption and
temporary storage are carried out when the liquid flows through by means of downward pulling of the synchronous traction mechanism, the situation that the liquid directly and rapidly washes delicate
seedling root systems and cultivation media is avoided, and the
seedling cultivation efficiency is improved. Root suffocation and matrix loss are prevented, pump-free gravity-driven cultivation liquid conveying is achieved, energy is saved, and the
system is stable.
