Aeroponics is a kind of optimum cultivation pattern for solving the current contradiction between water and gas in roots. This paper studies a new type of ultrasonic atomizing nozzle with focusing spherical shell cultivation,in order to overcome the shortcomings of existing high frequency ultrasonic atomizer in atomization cultivation,which the atomization quantity is small, the droplet distribution is uneven, and the atomization reliability is poor. The main structural dimensions of ultrasonic spray nozzle for focusing spherical shell are designed by theoretical analysis and formula deduction.The experiment shows that the atomizing effect of the atomizer is better and basically meets the needs of the atomization cultivation.It is also found that the ultrasonic frequency has a certain influence on the atomization effect of the atomizing nozzle.
