Combined type recyclable water culture barrel

The utility model discloses a combined type recyclable water culture barrel which comprises a planting barrel, a main liquid barrel cover assembly, an atomization main machine and a connecting pipeline. A nutrient solution is sucked out of the main solution barrel through the atomization main machine, high pressure is generated by the water pump in the atomization main machine and conveyed to all the planting barrels, vaporific water vapor is generated through the atomizer, and therefore the root systems of plants are fertilized, a time controller is arranged, and the time controller is used for controlling the operation of the atomization main machine and the planting barrels. Redundant vaporous water vapor is condensed into water drops, the water drops pass through a filter screen and reach a water return base, primary filtration is completed, the water drops flow back to a main water pipe through a water return pipe, the main water pipe is longitudinally connected to a water return pump connector in an ato
