The invention relates to the technical field of
seedling raising devices, in particular to a
seedling raising device and method for promoting the
germination rate of
cnidium monnieri seeds. The
seedling raising device comprises a seedling raising box, and the inner wall of the seedling raising box is provided with a reset rack and a starting rack which are distributed in parallel up and down and incline downwards; an inclined upward guide groove is formed in the inner wall, located above the reset rack, of the seedling raising box, and a tooth locking block is inserted into the guide groove in a sliding mode. By arranging the soil loosening mechanism, when a substrate is dry, a sleeve drives a
harrow wheel to rotate, so that the
harrow wheel slides along with a sliding seat while rotating, the effect of
punching holes in the substrate on a seedling raising plate is achieved, the situation that water cannot permeate due to substrate hardening is avoided, when the
humidity of the substrate is high, a gear is locked by a gear locking block, and the soil loosening effect is good. Therefore, the
harrow wheel on the sleeve drives the harrow nails to slide along with the sliding seat without rotating, then the harrow nails can turn over the substrate, the air permeability of the substrate is improved, and meanwhile water loss is accelerated.
