Effects of nozzle characteristics on the irrigation efficiency of atomized micro-sprinkler irrigation

In recent years, with the continuous advancement of science and technology, atomized micro-sprinkler irrigation systems have been widely used in agricultural irrigation. However, as one of the core components of the atomized micro-sprinkler irrigation system, the characteristics of the nozzle are crucial to the irrigation efficiency. So, how exactly do nozzle characteristics affect irrigation efficiency?
First of all, the flow rate of the nozzle is one of the key factors affecting irrigation efficiency. Larger nozzle flow can increase irrigation efficiency, but it also increases droplet size, leading to increased evaporation and runoff, which reduces irrigation efficiency. Therefore, when selecting a nozzle, it is necessary to select an appropriate nozzle flow rate based on crop water demand, soil type and climate conditions.
Secondly, the spray angle of the nozzle will also affect the irrigation efficiency. Smaller spray angles increase irrigation efficiency but also reduce the coverage area. A larger spray angle is suitable for areas with larger irrigation areas or areas that require uniform irrigation. Therefore, in practical applications, the appropriate spray angle needs to be selected according to specific conditions.
In addition, the size of water droplets is also an important factor affecting irrigation efficiency. Smaller water droplets evaporate more slowly and produce less runoff, making irrigation more efficient. Larger water droplets are prone to evaporation and runoff, reducing irrigation efficiency. Therefore, when selecting a nozzle, it is also necessary to select the appropriate droplet size based on crop type, soil type and climate conditions.
In addition to the above points, the type of nozzle also affects irrigation efficiency. Common nozzle types include single-hole nozzles, multi-hole nozzles and vortex nozzles. The single-hole nozzle sprays water droplets of uniform size, while the multi-hole nozzle can produce smaller water droplets. The vortex nozzle uses the principle of rotating vortex to spray fine and uniform water mist, covering a larger area. Therefore, when selecting a nozzle, it is also necessary to select the appropriate nozzle type according to specific needs.
