[0027] like Figure 1 , Figure 2 and Figure 3 A hydroponic cultivation device shown includes: a water tank 1 and a water pump 2, wherein the water pump 2 is arranged inside the water tank 1, and the device also includes a tidal pipe and a circulating pipe 4, the discharge port of the water pump 2 is connected to the water inlet 3 of the tidal pipe, a water level limit pipe 8 is arranged inside the tidal pipe, and the internal thread of the water level limit pipe 8 is connected to a downpipe 9, the downpipe 9 is connected to the water tank 1, the tidal pipe is connected to the circulating pipe 4, a plurality of planting troughs 5 are connected to the circulating pipe 4, and a planting basket 6 is arranged on the planting trough 5.
[0028] The above-mentioned hydroponic cultivation device uses a water pump 2 to pump the water in the water tank 1 into the tidal pipe and the circulation pipe 4.

The water level limit pipe 8 and the downpipe 9 are threadedly connected to adjust the height of the water level limit pipe 8, thereby realizing the advance setting of the maximum water level. When the water level in each planting trough 5 and the tidal pipe exceeds the maximum water level set in advance by the water level limit pipe 8, the water exceeding the height will be discharged into the water tank 1 through the downpipe 9 by using the siphon principle, so as to realize the reciprocating circulation. The artificially controllable water level rise and fall and circulation greatly improve the oxygen content of the plant root environment, thereby reducing the disease problems caused by anaerobic respiration of plants, such as the harm of anaerobic bacteria to plants, and the toxicity of anaerobic respiration products of plant roots to the plants themselves, etc., effectively reducing the root temperature to create an aerobic environment, and preventing root rot.
