What are the common irrigation methods in agricultural production?

Irrigation can be divided into traditional irrigation and water-saving irrigation. Traditional irrigation refers to the method that irrigation water enters the field from the surface and directly penetrates into the soil, mainly including flood irrigation and flood irrigation. Flood irrigation is to divide the irrigated land into many ridged grid fields. During irrigation, the water layer in the grid field keeps a certain depth, and the soil is wetted by excessive force. In the case of no field irrigation project or simple project, after water is introduced into the field, if it overflows into the soil, it is flood irrigation; Water-saving irrigation measures include canal seepage control, water-saving ground irrigation, low-pressure pipeline irrigation, sprinkler irrigation, drip irrigation, spring irrigation, infiltration irrigation and micro-spraying. Compared with traditional irrigation, water-saving irrigation is water-saving, labor-saving and energy-saving, which is the development trend of modern urban agriculture and the way to realize efficient utilization of water resources.
