THE INFLUENCE OF DESIGN PARAMETERS THE DEFLECTOR NOZZLE WITH AN ANNULAR GROOVE ON THE QUALITY OF THE RAIN
The materials consider the main problems of the use of deflector nozzles for irrigation of crops on heavy soils. The new design of the deflector nozzle allowing to create a fine-drip rain is presented. The results of laboratory and field studies to determine the optimal design parameters of the sprinkler nozzle deflector type with an annular groove ensuring the creation of optimal sizes of raindrops and irrigation uniformity with minimal impact of rain on the soil and plant.
