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 partial root-zone drying and alternate partial root-zone irrigation treatments reduced tobacco water consumption and tobacco yield, but tobacco water use efficiency increased with 7.5% and 11.2%, N and K contents of middle leaves treated with N 0.20 g/kg soil enhanced 23.1% and 25.2%, 33.6% and 59.8%, respectively when compared to the conventional irrigation treatment.

结果表明，在不同施N水平下，与常规灌溉相比，部分根干燥灌溉和分根区交替灌溉的烤烟耗水量下降，产量有所减少，而水分利用效率提高7.5%和11.2%；施用N 0.20 g/kg土时，PRD和APRI中部叶N含量分别提高23.1%和25.2%，K含量分别提高33.6%和59.8%。

These results provide the scientific basis for determining suitable irrigation frequency and the irrigation volume of papermaking wastewater in saline reed field of Yellow River Delta, which is of great significance to the exploitation and utilization of papermaking wastewater resources.

该研究为黄河三角洲内陆盐碱地区芦苇群落在造纸废水灌溉下的适宜灌溉次数和灌溉水量的确定提供了科学依据，有利于造纸废水资源的合理化开发利用。

To study the effect of papermaking wastewater irrigation on soil hydrological properties in saline reed field, different wastewater irrigation frequencies were employed in the saline reed field of Yellow River Delta. Soil infiltration course and hydrological properties were determined in field and laboratory. After wastewater irrigation, the change of the soil pH value, soil salt content and soil hydrologic-physical properties were observed. The results were showed that: 1 After wastewater irrigation, the mean reduction of soil pH value was 6.0%.

为研究造纸废水灌溉对黄河三角洲内陆盐碱芦苇地土壤水文特征的影响，通过设置芦苇地不同废水灌溉次数下的随机区组试验，采用田间测量土壤入渗过程和实验室内测定水文物理参数相结合的方法，分析造纸废水灌溉前后土壤pH值、含盐率及土壤水文物理参数的变化。
