Research Status of Water and Fertilizer Integration under Mulch Drip Irrigation for Potato

Water and fertilizer integration under mulch drip irrigation was advanced irrigation and fertilization techniques and cultivation techniques integration.It′s an efficient water-saving and fertilizer-saving technology，which was one of the hot spots in current research field.Current status of low domestic agricultural fertilizer use efficiency was firstly elaborated，and then development of fertigation under drip irrigation was briefly reviewed.Water and fertilizer requirement rule under drip irrigation，soil water and salt migration rule were summarized.Main problems existing in technology of drip irrigation under film were analyzed，corresponding countermeasures and prospects for future research and exploration needs further direction were put forward，with a view to water and fertilizer integration in application of potato cultivation reference.
