This invention relates to the field of seed germination devices, specifically to a seed germination device for canna lily cultivation. It includes a germination tank, a support frame positioned at the top of the tank's inner cavity, a heating mechanism positioned within the tank's inner cavity, and an aerator positioned at the bottom of the tank's inner cavity. An outer sleeve is mounted on the support frame, and an inner sleeve is located inside the outer sleeve. A first support plate with a first through hole is slidably mounted inside the inner sleeve. A high-position fixing component is positioned between the outer sleeve and the inner sleeve. This device uses the first support plate to push the seeds to a high position for temporary fixation, and after descent, the seeds fall naturally in a parabolic trajectory due to gravity. This achieves the effect of gently tumbling and repositioning the seeds without mechanical blade contact or water flow impact, effectively solving the problems of existing static soaking leading to oxygen deficiency and seed rot, and existing mechanical stirring blades causing seed tearing and embryo damage due to rigid impact.
