Multi-layer type seedling culture equipment comprises a frame body, wherein a plurality of stacked accommodating spaces are formed in the frame body, a seedling culture groove for placing a seedling and nutrient solutions is formed in the bottom of each accommodating space, a nutrient solution supplement inlet for maintaining liquid levels of the nutrient solutions and an inflation inlet for increasing the dissolved oxygen of the nutrient solutions are arranged in each seedling culture groove, and a lamp for providing light rays required for providing seedling photosynthesis and inhibiting vain growth of the seedling is arranged above the seedling culture groove in each accommodating space. According to the equipment, due to adoption of the multi-layer seedling culture grooves, the space can be utilized as much as possible； nutrient solution supplementing devices depending on the atmospheric pressure principle are adopted, so that the nutrient solutions can flow out automatically to supplement the nutrient solutions in the seedling culture groves when the liquid levels of the nutrient solutions in the seedling culture grooves are lower than positions of the nutrient solution supplement inlets； inflators are used for directly inflating the nutrient solutions through the inflation inlets to increase the dissolved oxygen of the nutrient solutions； and the equipment is simple in whole structure and extremely low in cost.一種多層式育苗設備，包括一框架主體，該框架主體形成有複數層疊的容置空間，各該容置空間底部設有一放置種苗及養液的育苗槽，該育苗槽內設有一維持養液液位的養液補充進口及一增加養液溶氧量的打氣進口，各該容置空間內該育苗槽上方設有一提供種苗光合作用及抑制種苗徒長所需光線的燈具。本創作因採用多層的育苗槽而可對空間最大化利用，且採用依大氣壓力原理的養液補充器而可在育苗槽內養液液位低於養液補充進口位置時自動流出養液以補充育苗槽內的養液，再採用打氣機通過打氣進口對養液直接打氣而可增加養液溶氧量，整體架構簡單且成本極低。
