Abstract: In order to get full advantages of aeroponics technology and further enrich the aeroponics technology system, a new aeroponics production system of nutrition solution supply pipeline below the ground was designed. The aeroponics production system included the control system, nutrition solution supply pool, power force system, nutrition solution supply pipeline, aeroponics bed, excess nutrition solution return pipeline, etc. The aeroponics bed could have no interference rotation and could smooth supply and return circulation of nutrition solution.Nutrition solution supply pipeline and excess nutrition solution return pipeline were arranged orderly below the ground. The control system used PLC, which maintained high quality and stability of nutrition solution environment through continuous monitoring and regulation of the EC sensor, temperature sensor, nutrition solution level sensor and execution components, ensured the safety and stability of the nutrition solution supply process through the real-time monitoring of the pressure sensor and water flow sensor of main nutrition solution supply pipeline and each key nutrition solution supply pipeline, and guaranteed the timed, quantitative and accurate supply of each supply unit through the timer and solenoid valves of the main supply line. The production system had no emission and zero pollution,creating conditions to further promote the application of aerosol technology in facility agriculture.

Key words: aeroponics, production system, soilless cultivation, facility agriculture
