The invention provides a method for planting edible sunflowers in original soil of severe saline-alkali soil through saline water drip irrigation. The method comprises the following steps: (1) land preparation, ridge culture and film mulching: subsoiling the salinized land, carrying out rotary tillage, and carrying out ridging, drip irrigation tape laying and film mulching on the land subjected to rotary tillage in sequence; (2) sowing edible sunflower seeds: mixing edible sunflower seeds with a seed treating agent for seed dressing, and then sowing; (3) soil moisture content monitoring: at least three soil moisture content monitoring points are selected in the field, and a soil moisture content monitoring vacuum meter negative pressure meter and/or an electronic negative pressure meter are/is buried under a water dropper at each point; and (4) salt water drip irrigation water-salt regulation and control: dividing the irrigation period from sowing to harvesting of edible sunflowers into three stages of sowing
