The nutrient solution water level that this creation mainly provides one kind and water can be enabled to plough plant generates the irrigation rig moved back that rises such as tide. Nutrient solution in reservoir is sent by the irrigation rig by a gang of Pu via infusion pipeline plants in raw container,And by under the control of liquid back pipe road and water level valve,The nutrient solution planted in raw container is enabled to be maintained at preset height of water level； In particular,The growth characteristics control water level valve events of plant can be ploughed according to water,The nutrient solution planted in raw container is released,In the raw container of the plant that nutrient solution is re-fed into the area Zhi Zai again through a period of time Hou,It is consequently formed to rise just like the nutrient solution water level as tide and moves back variation effect,It allows the water of plantation to plough plant root to have an opportunity to expose to the open air in the high oxygen containing environmental condition of high humidity,Make water plough plant root roots development it is comparatively vigorous,Quickly,And then promote the production quality that water ploughs plant.本創作主要提供一種可令水耕植物之養液水位產生如潮汐般漲退的灌溉裝置。所述灌溉裝置係由一幫浦將儲液槽中的養液經由輸液管路送入植生容器中，且由回液管路及水位閥之控制下，令植生容器中的養液保持在預設的水位高度；尤其，可依照水耕植物之生長特性控制水位閥動作，將植生容器內的養液洩放，經一段時間後再將養液重新送入植栽區之植生容器中，由此形成有如潮汐般之養液水位漲退變化效果，讓種植的水耕植物根部有機會曝露在高濕高含氧的環境條件當中，使水耕植物根部之根毛發育相對較為旺盛、快速，進而提升水耕植物之生產品質。
