This creation is that system of a kind of hydroponic culture structure and application,It is to be made of a perfusion tube,One end of at least corresponding water outlet of what is equipped with a flow guiding connector in the perfusion tube both ends,The Pipe System Conveying Fluid is made of a hollow tube,And the perfusion tube both ends are respectively defined as a water inlet end and a water outlet,The perfusion tube center have always pierce into,The diversion space of water outlet,The periphery of perfusion tube is formed with the receiving hole of plural opening upwards again,Again aforementioned flow guiding connector at least for set what perfusion tube water outlet one end,And the grade flow guiding connectors have one can be arranged what infusion tube end adapter tube portion and one for flow direction-changing bent portion,The wherein internal diameter in the internal diameter of bent portion small what adapter tube portion,It enables and is formed with a class's drop section collected to bent portion between flow guiding connector what adapter tube portion and bent portion,Make the water storing unit that a certain height is formed with below perfusion tube what diversion space,Thereby,With it is recyclable,And can spill-over effect,Culture solution or water flowing can be provided,And culture solution or water are recycled,Reach the purpose for saving resource,And keep culture solution or water uniform by temperature,And can be effectively controlled the nutrient solution water level in the area perfusion tube Zhi Zai,And can instantaneously changing culture solution,The multi-party demand that water ploughs plantation can be met,And it can increase the practicality.本創作係一種水耕栽培結構及應用彼之系統，其係由一輸液管所構成，該輸液管兩端中至少於對應出水的一端設有一導流接頭，所述之輸液管係由一中空管體所構成，且該輸液管兩端被分別定義為一進水端及一出水端，該輸液管中央具有一貫穿進、出水端之導流空間，又輸液管之周緣形成有複數開口向上之容納孔，又前述之導流接頭至少可供設於輸液管之出水端的一端，且該等導流接頭具有一可套設於輸液管端部之接管部及一供水流轉向之彎管部，其中彎管部之內徑小於接管部之內徑，令導流接頭於接管部與彎管部間形成有一向彎管部收束之階級落差段，使輸液管於導流空間下方形成有一特定高度之貯水部，藉此，具有可循環、且可滿溢之作用，
