During the irrigation management system operation, water level detecting and meteorological soil moisture index are inputted to control device for irrigating 6 first
In, when the moisture content of agricultural land soil reaches irrigation index, agricultural land soil monitor 7 sends signal to control device for irrigating 6, fills
Irrigate control device 6 and start immersible pump and control valve and farmland is irrigated, when rainy season or irrigation level exceed irrigation index, agriculture
Field soil monitor 7 sends signal to control device for irrigating 6, and control device for irrigating 6 notifies administrative staff through wireless network, by people
Work opens drainage gate 27, and to reduce or drain farmland water, the farmland water of discharge enters drainage ditch 14 through drainpipe 26, then flow back or
Irrigation pumping station 2 is pumped into, is recycled with collecting, avoids the waste of water resource.The farmland automatic intelligent irrigation management system is real
Water level fine-grained management is showed, has created optimum growh environment for crop, the growth of crop can be promoted, improve the yield of crop；
Strengthen the scientific management of water resource, so realize water resource really fully, reasonably utilize, reached water-saving
Purpose, while reduce labour cost.On the other hand, the farmland automatic intelligent irrigation management system uses piping transportation water irrigation
Mode, its pipeline is buried to be not take up cultivated area in field face or in the case where producing road, can save the dykes and dams needed for existing feed ditch dike and account for
With area 3-5%, the utilization rate in original soil is largely improved, there is positive social effect.
