The plant cultivation device of this creation, which includes at least, to be had: groove body,Feed flow component and leakage fluid dram,The groove body system has a bottom,And bottom periphery closing is enclosed equipped with rib,And an open space is formed,The feed flow component have a what rib side inlet,Component and controller are drawn,The controller can control this to draw the movement of component,And then entered in the open space with intermittence supply nutrient solution by the inlet,And the leakage fluid dram position what rib is with respect to the side of the what inlet,The bottom of the high what groove body of the bottom system of the leakage fluid dram,Under running using the feed flow component and leakage fluid dram,Water level of the nutrient solution generation such as tide in open space can be enabled to rise and move back variation effect,Planted plant root is allowed to have an opportunity to expose to the open air in the high oxygen containing environmental condition of high humidity,Make the roots development of plant root it is comparatively vigorous,Quickly,And then promote the production quality of plant.本創作之植物培養裝置至少包含有：槽體、供液構件以及排液口，該槽體係具有一底部，而該底部周邊封閉圍設有擋邊，並形成一開放空間，該供液構件具有一位於該擋邊一側之進液口、汲取組件以及控制器，該控制器可控制該汲取組件之動作，進而以間歇性供應養液由該進液口進入該開放空間內，而該排液口位於該擋邊相對於該進液口之一側，該排液口之底部係高於該槽體之底部，利用該供液構件以及排液口之運作下，可令開放空間內的養液產生如潮汐般之水位漲退變化效果，讓所種植的植物根部有機會曝露在高濕高含氧的環境條件當中，使植物根部之根毛發育相對較為旺盛、快速，進而提升植物之生產品質。
