摘　　要：氮素作为马铃薯必需营养元素之一,对马铃薯产量、品质影响巨大,其中氮素对源-库关系的调控是重要原因。本文系统论述了氮素在基追比、数量和形态等方面对马铃薯源端、库端及其相互关系的影响。同时对有一定研究价值的问题进行思考和展望,以期对马铃薯氮素高效利用和提质增产提供理论参考。Nitrogen,as one of the essential nutrients in potato,has a great influence on potato yield,and quality and the regulation of nitrogen on source-sink relationship is an important factor.This paper systematically discusses the effects of nitrogen on potato source end,sink end and their interrelationships in terms of dressing ratio,quantity and form.At the same time,some problems with certain research value were also considered and prospected to provide theoretical reference for high-efficiency utilization of nitrogen,improvement of quality and yield of potato.
