The results showed that (1) compared with conventional N treatment, the N loss of economic N treatment reduced while NUE and N residue in soil improved under water-saving condition;(2) Use efficiency of fertilizer applied as basal fertilizer was higher than that as top-dressing fertilizer under water-saving condition;(3) The fertilizer N residue rate was from 29% to 41%, and 60% of N residue, which distributed in 1m depth soil concentrated in 0～20cm surface layer;(4) In whole growing stage of wheat, fertilizer N hadn't leach to 130cm depth;(5) NUE of economic N treatment under conventional irrigation decreased by 16.6% compared with the same N treatment under water-saving condition.

结果表明，与常规施氮量处理相比，节水灌溉条件下节肥施氮量处理的氮肥损失率降低，氮肥当季利用率和土壤残留率提高；基施氮肥的利用率高于追施氮肥；土壤肥料氮的残留率在 2 9%～ 41 %之间，分布于 1m土层中，其中60 %以上集中在 0～ 2 0cm土层；在整个小麦生长季内，肥料氮并没有淋洗到 1 30m以下。节肥施氮量在常规灌溉下的当季利用率比在节水灌溉下降低 1 6 6%。

The results showed that compared with soil culture, the root cap was not obvious with less amyloplast and polysaccharose substance under water culture. The root epidermis under water culture was thinner than that of soil culture, with little root hair or not, in which cortex parenchyma tissue developed with big cell, solution proliferative aerenchyma in intercellular space, and thin cell wall. However, the root cap under soil culture was big, with strong PAS reaction and no aerenchyma tissue.
