The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

A greenhouse water culture system is shown in figure 1 and comprises a mixing pool 1 and a plurality of liquid level solution barrels 17, wherein each solution barrel is provided with a liquid passing port 2, the liquid passing ports are simultaneously connected with a water inlet pipeline 3, a liquid supply pipeline 4 and a waste water pipeline 5, and each pipeline is provided with a ball valve for controlling the on-off of each pipeline respectively. For example, the water inlet pipeline is opened when water needs to be fed, and the water inlet pipeline can be closed after the solution in the corresponding solution barrel is prepared. When the solution needs to be supplied to the mixing pool, the solution supply pipeline is opened to supply the solution to the mixing pool. And when the solution barrel needs to be cleaned, the ball valve can be opened to enable the waste water pipeline to be communicated with the solution barrel, and the interior of the barrel is completely drained.

The liquid supply pipeline of each solution barrel is communicated with the mixing tank, the water inlet pipeline is connected with a main water supply pipe 6, each waste water pipeline is connected with a sewage discharge pipe 7, and waste water is discharged to sewage treatment equipment for treatment, which is not described again; a water supply pipe 8 and a liquid return pipe 9 are connected to the mixing pool, a liquid inlet branch pipeline 10 is connected between the water supply pipe and each water culture bed 16, and a liquid return branch pipeline 11 is connected between the liquid return pipe and each water culture bed; still be connected with punch press pipe 12 on the main water supply pipe, install the water control valve on the punch press pipe, when needs wash the planting groove, just open the water control valve, supply water to the punch press pipe, usually, the water control valve adopts the stop valve can.

The solution barrel comprises a liquid barrel A, a liquid barrel B and an acid liquid barrel, and stirring devices used for stirring the solution in the barrels are arranged on the liquid barrel A and the liquid barrel B.

The stirring device comprises a stirring shaft and a stirring motor 13 for driving the stirring shaft, wherein one end of the stirring shaft extending into the corresponding solution barrel is provided with a stirring paddle, the stirring motor is connected with a controller 14, the stirring motor is controlled by the controller to be opened and closed, the controller adopts a conventional PLC (programmable logic controller), and the motor can be controlled to be opened and closed. The person skilled in the art can design the connection driving form of stirring motor and (mixing) shaft as required, both can be that each (mixing) shaft is driven by a stirring motor, also can utilize same stirring motor to drive each (mixing) shaft simultaneously, as long as can realize that stirring motor drives the (mixing) shaft and rotate can, because utilize motor drive (mixing) shaft to rotate and belong to current conventional technical content, no longer describe herein.

As an example, the liquid return pipe is made of a PVC pipe with the diameter of 90 mm. The liquid supply pipeline is made of a PVC pipe with the diameter of 20 mm. The water inlet pipeline, the waste water pipeline and the punch pipe are all made of PVC pipes with the diameter of 32 mm. The main water supply pipe and the water supply pipe are both made of phi 63mm PVC pipes.

The liquid level in the solution barrel is higher than that in the mixing pool. That is, the solution bucket all is higher than the pond of thoughtlessly joining in marriage and arranges, and in this embodiment, only need utilize the confession liquid pipeline to switch on between solution bucket and the pond of thoughtlessly joining in marriage, can need not to set up pumping device and can realize that solution is along solution bucket inflow thoughtlessly joining in marriage the pond. The solution supply is controlled by a valve, and the flow meter 15 measures the solution supply amount, in an alternative embodiment, in the implementation, the valve action on the liquid supply pipeline may be controlled by a feedback signal of the flow meter, or a commercially available flow meter valve is directly installed on the liquid supply pipeline, and the liquid supply pipeline can be controlled to be switched on and off according to a set value, for example, when the solution supply amount reaches the set value, the flow meter control valve is automatic.
