Abstract: The present invention discloses a stacked tray container seedling apparatus formed by at least two identical tray containers, and each tray container has cells and through holes arranged alternately and regularly with each other. The cells of a tray container are stacked onto the through holes of another tray container respectively for a central management or transportation of all stacked tray containers, such that seedlings in the tray container together with the tray container can be moved directly to a cultivated area for cultivations. The cell includes one or more positions higher than the through hole at the bottom of the cell for storing an appropriate quantity of water for a better growth of vegetables.
