The cultivation of crops is inseparable from the water source, because they need irrigation, and they must be discharged in time when there is a lot of rain.


Traditional way:Around the water source, build dams and use high and low water levels to irrigate farmland.

Problem:The water level of the water source drops, and it is difficult for the dam to store water.

Solution:In the low water area around the water's edge, an integrated pumping station for farmland irrigation is established for collecting water sources and forcing irrigation of crops.
