What are the advantages of using water-saving irrigation in agriculture?

The water saved by water-saving irrigation can expand the irrigated farmland area, thus increasing the yield. On the other hand, the use of water-saving irrigation is conducive to the use of scientific methods for irrigation. Using water-saving irrigation can be carried out on time and according to crop growth demand, which is beneficial to crop growth. The use of drip irrigation for crops is to save water first, and then drip irrigation for a long time is more suitable for crop growth, and there will be no root rot and other phenomena, which will eventually make crops grow healthily and improve yield.
