Abstract: In order to solve the needs and problems of home sprout cultivation, the basic design requirements of the home sprout cultivation device were put forward. An automatic cultivation device for home sprouts was designed, which was composed of base, cultivation frame, germination system, irrigation system, light supplement system and control system. The results showed that the three-dimensional cultivation mode was adopted to improve the utilization rate of cultivation space; the special germination chamber could make the seeds sprout orderly in the germination stage, avoiding the problems of uneven germination and rotten seeds; the automatic irrigation water circulation could meet the water demand in the growth stage of sprouts, reducing the phenomenon of poor growth and rotten roots; it had the function of automatic intelligent light supplement. It could solve the problem of slow growth and inconsistent growth caused by insufficient light, realize the automatic control in the cultivation process, and solve the problem of the heavy workload of home cultivation management. It had a beautiful appearance and simple operation.
