## Abstract

The present invention provides a nursery block, including a nutritive block for providing nutrients to seeds. The top of the nutritive block is provided with a seed placement pit. The seed placement pit is internally provided with a seed cultivation pit. The seed placement pit is of a structure with a big top and a small bottom so that the seeds fall into the seed cultivation pit along the surface of the seed placement pit under the action of gravity. The seed cultivation pit is internally provided with a notch which extends in a direction away from the seed cultivation pit and provides growth paths for root systems of the seeds. The present invention can improve the sowing efficiency, stabilize and moisten seeds and improve the overall germination rate and germination uniformity of the seeds, and is convenient for mechanized sowing.
