Automatic aerator system for deep liquid culture and deep liquid culture system

Abstract

The invention provides an automatic aerator system for deep liquid culture and a deep liquid culture system. The automatic aerator system includes a gas supply pipeline, a detection device and a control system. The gas supply pipeline includes a main gas supply pipeline body, a first branch pipeline body and a second branch pipeline body. The second branch pipeline body is arranged in a planting groove, one side of the second branch pipeline body is provided with an exhaust hole, oxygen is discharged from the exhaust hole, and the direction of air flow is same as the flow direction of a nutrient solution in the planting groove. The detection device is located in the planting groove and used for detecting the oxygen content in the planting groove and sending a corresponding detection signal. The control system is connected with the detection device and the gas supply pipeline and used for receiving the detection signal and conduct flow control over the gas supply pipeline according to the detection signal so as to adjust the oxygen supply content. The provided automatic aerator system for deep liquid culture can achieve automatic regulation of the oxygen supply amount and can achieve the moderate oxygen supply to crops.

Description

technical field [0001] The invention relates to the field of plant cultivation, more specifically, to a deep liquid culture automatic oxygenation system and a deep liquid culture system comprising the deep liquid culture automatic oxygenation system. Background technique [0002] At present, soilless cultivation generally adopts the nutrient solution planting method. Since the root oxygenation is rarely carried out, especially when leafy vegetables are planted in summer, due to the high ambient temperature, the temperature of the nutrient solution increases, resulting in a rapid decrease in the dissolved oxygen in the nutrient solution. It makes the roots of leafy vegetables anoxic and rots, which has a great impact on the production of leafy vegetables. [0003] Existing technical solutions generally adopt the method of adding oxygen enhancer to supply oxygen, which consumes a lot and costs high. Contents of the invention [0004] The present invention aims to solve at l...
