The tidal type cultivation device of this creation,It is the cultivation bed that one layer frame of what is equipped at least two layered configurations,Equipped with one for storing nutrient solution and the nutrient solution that stored nutrient solution is delivered to top layer's cultivation bed being cooperated to convey mould group,Separately there are at least two siphon pipes to be separately connected between what upper and lower level cultivation bed and between the reservoir of the cultivation bed and nutrient solution of lowest level conveying mould group； Stop supplying nutrient solution Hou to the cultivation bed of layer frame when nutrient solution conveys mould group,Can under the lasting siphonage of siphon pipe,Nutrient solution in the cultivation bed of siphon pipe upper layer is pumped in the cultivation bed of lower layer,Until upper layer cultivation bed in the low what siphon pipe of nutrient solution water level nozzle and stop,The nutrient solution height of water level in each cultivation bed is set to drop to the low water level of the nozzle height of low what siphon pipe from original full-water level. So that it is enough with relatively low equipment, operating cost, so that each cultivation bed is generated the irrigation effect such as tide.本創作之潮汐式立體栽培裝置，係於一層架設有至少兩個分層配置的栽培槽，設有一供儲存養液且配合將所儲存之養液輸送至最上層栽培槽的養液輸送模組，另有至少兩個虹吸管分別連接於上下層栽培槽之間及最下層之栽培槽與養液輸送模組之儲液槽之間；當養液輸送模組停止對層架的栽培槽供應養液後，可在虹吸管之持續虹吸作用下，將虹吸管上層栽培槽當中的養液抽吸至下層的栽培槽中，直至上層栽培槽當中的養液水位低於虹吸管之管口而停止，使各栽培槽中的養液水位高度從原先的滿水位下降至低於虹吸管之管口高度的低水位。俾能夠以相對較低的設備、運作成本，使各栽培槽產生如潮汐般的灌溉效果。
