摘　　要：在大田试验条件下,研究了水氮互作对冬小麦产量和水分利用率的影响。结果表明,干旱胁迫影响了氮肥的作用,在不同灌溉量的水分条件下,氮肥的作用得到充分发挥,水分和氮素配合不仅有利于提高产量,也有利于提高冬小麦水分利用率。The field culture was conducted to study the effect of water and nitrogen cooperation on grain yield and water use efficiency in winter wheat. The results showed that the effect of N fertilizer was inhibited seriously by water stress, only with the condition of water and nitrogen coordination, it was developed abundantly. There by, N fertilizer could not only increase winter wheat yields but also improve water use efficiency in winter wheat.

关 键 词：冬小麦 产量 水分利用率 水氮效应
