Water supplementing process for crops

The invention discloses a water supplementing process for crops. A concrete platform of 1*2m is poured on one side of a river bank, then a water pump is installed on the surface of the concrete platform, a water inlet of the water pump communicates with a first pipeline, then the other end of the first pipeline is placed into a river, a water outlet of the water pump communicates with a flow meter, the other end of the flow meter communicates with a second pipeline, the other end of the second pipeline communicates with a tee pipe, one water outlet of the tee pipe extends to an irrigation place of crops, and another water outlet of the tee pipe communicates with a drip irrigation pipe. By adopting the designed water supplementing process, water can be supplemented intelligently and automatically to the crops, water can be accurately supplemented with according to different planted crops, controlling can be remotely carried out via the Internet, solar power generation can be used for power generation, energy c
