The utility model relates to a box structure of a fish and vegetable symbiosis, comprising: a planting box having an accommodating space for planting a plant, the surface group of the accommodating space is provided with a siphon assembly, and the siphon assembly is composed of a siphon clock and a siphon tube. The siphon clock is arranged above the siphon tube, and a water inlet is formed around the siphon clock, and a water outlet is formed below the siphon tube； when the creation is performed, when the liquid level of the water source in the siphon clock is higher than the overflow water level of the siphon tube, When the overflow flow is greatly increased, the siphon clock forms a vacuum area above the siphon tube to form a siphon phenomenon, so that the water source can be discharged from the water outlet continuously and in a large amount, and when the water source returns to the water inlet of the siphon clock. At the height of the siphon, the siphon phenomenon can be destroyed, and the water level in the planting box can be circulated as a tide.一種魚菜共生之箱體結構，包含：一栽種箱，具有一容置空間，供以栽種一植物，容置空間之表面組設有一虹吸組件，虹吸組件由一虹吸鐘及一虹吸管所組成，虹吸鐘裝設於虹吸管之上方，虹吸鐘之四周分別成型有一入水口，虹吸管之下方形成一出水口；本創作實施時，當虹吸鐘內之水源之液面高於虹吸管的一溢流水位，且溢流量大增時，使虹吸鐘相對於虹吸管之上方形成一真空區，以形成虹吸現象，讓水源可持續地、大量地由出水口排出，而當水源之水位回復至虹吸鐘之入水口的高度時，虹吸現象可被破壞，進而使栽種箱內之水位可如潮汐般循環作用。
