The invention discloses a large-ridge and double-line under-film drip-irrigation water-saving cultivation method of winter and early spring potatoes. The method comprises the following steps of (1) potato seed selection and treatment, (2) seeding, (3) drip-irrigation equipment laying and plastic film mulching, and (4) field management. The cultivation method is a water-saving irrigation technology combining a large-ridge and double-line technology, a plastic film mulching technology and a drip-irrigation technology organically, has a particularly remarkable effect in arid and semi-arid regions, integrates the edge line advantage, maintenance of the optimum water content of root regions, effective improvement of the ground temperature, evaporation suppression and water saving, has the characteristics of preserving soil moisture, maintaining fertilizers, keeping warm, remarkably improving utilization of optical energy, water and the fertilizers, saving the water, saving labor, increasing a yield and improving the efficiency, and has the advantages of saving the water and the labor, increasing the yield and improving the efficiency. |
