摘　　要：对宁夏中部干旱带旱地马铃薯覆膜条件下水肥配施技术进行了试验研究,结果表明:宁南旱地马铃薯生产中,肥料施用应采取氮、磷、钾肥配施有机肥,并采取单位面积补灌量225 m3/hm2,可有效改善作物长势、增强抗逆性,提高作物产量,提升水分生产效率,促进水资源的高效利用。An experiment was conducted on the water and fertilizer co-application technology for dry-land potato under the condition of film-mulching in the Middle Arid Zone of Ningxia. The results showed that in the dry-land potato production in the Middle Arid Zone of Ningxia, nitrogen, phosphorus and potassium fertilizer should be combined with organic fertilizer and a supplementary irrigation with 225 m3/hm2 of water should be made in order to effectively improve crop growth, enhance stress resistance, improve crop yield, improve water production efficiency, and promote the efficient use of water resources.
