Key points for controlling orchard parameters with 160 irrigation nozzles

Pressure control: Avoid being too high or too low

160 irrigation nozzle for orchard irrigation requires medium and low pressure (0.2-0.4MPa): excessive pressure can cause fine water mist 

(evaporation loss exceeding 30%) and easily damage young leaves; 

If the pressure is too low, the range will be shortened and the coverage will be uneven. It is necessary to monitor the pressure of the pipeline 

network in real time and adjust the power of the water pump in a timely manner.

Irrigation time and frequency control

Avoid high temperature irrigation at noon: Use a 160 irrigation nozzle in the early morning or evening to irrigate, as evaporation is low and 

excessive temperature differences should be avoided from stimulating fruit trees;

Avoid "fixed duration irrigation": it needs to be adjusted according to soil moisture, which can be determined by the "soil sampling method": 

remove the top 10 centimeters of soil, and if the soil below cannot be dispersed by hand, there is no need for irrigation.
