Abstract: In view of nonstandard operation of potato water and fertilizer integration irrigation system in China，technical specification of potato water and fertilizer integration was formulated.Potato water and fertilizer integration irrigation is the best irrigation method recognized in the world.Potato water and fertilizer integration irrigation can not only greatly reduce use of agricultural irrigation，but also significantly reduce use of chemical fertilizers and pesticides，which plays a very important role in protecting environment and purifying groundwater.Combined with agronomic requirements of potato planting and operation requirements of water and fertilizer integration，operation technology process of intelligent potato water and fertilizer integration system was formulated，and facility requirements，hardware system operation and potato agronomic planting were standardized.It provides a reasonable technical reference for majority of potato planting users，and provides a theoretical basis for popularization of high-efficiency drip irrigation，fertilization and application of potato.
