The invention relates to an automatic irrigation-drainage system for farmland. Irrigation water enters a water level control pond through a water level control valve; a floating ball drives the water level control valve to regulate the water supply amount until the supplied water is equal to the consumed water; the water level is stabilized at a certain water level when the water supply of the water level control valve is stopped at a water supply water level h1; the irrigation water enters a soil filling region at the upper part in a U-shaped concrete groove through a nonfine concrete cover plate and a sand inverted filter from the bottom of the inner part of the U-shaped concrete groove so as to form a soil saturated water layer lower than h1; the water in the saturated water layer is raised to the root layer of the crop in the form of capillary water; the water supply amount is increased or reduced along with water consumption amount so that the farmland is automatically irrigated; because the h1 is lower than the height h2 of the upper edge of the U-shaped concrete groove, no gravity water is leaked; once the soil saturated water layer is higher than the h1 because of raining, the water level control valve is turned off, the irrigation is stopped; if the water layer is higher than the upper edge h2 of the water level control pond, the water overflows to a water accumulation pond, and the water begins to be discharged; and the irrigation is recovered until the soil saturated water layer is lower than h1.
