Abstract : For making water resource valid used in agricultural irrigation ,to develop
new-type agricultural water-saving irrigation system can overcome the shortcomings of the traditional way of
irrigating .This design sets up the modernized
agricultural sprinkling irrigation model. because the area
of every belt area is different, the flow of the necessary water is different.
Using a lot of different nozzle among sprinkling irrigation system, it is possible to make
round sprinkling irrigation of district even, according to
nozzle with controlling the flow of water diameter of spray nozzle ,in addition , it casts the iron pipe distance and reduces losses of ink greatly to adopt. Adopting centralized control in
the nozzle system, the automatic degree becomes high and easy to regulate .
