Water resource shortage and water pollution limit the sustainable development of rural areas.Piggery wastewater reuse can balance these two problems.In this paper，variation of growth indicators in summer maize was studied by the field experiment，which was with regard to different level of nitrogen fertilizer interaction with different irrigation quantity and frequency of piggery wastewater treated by anaerobic fermentation system.Meanwhile，coupling effect of water and fertilizer on the yield and water use efficiency of summer maize was researched，on basis of water and fertilizer data，the model of summer maize yield was built and validated in order to provide references for piggery wastewater irrigation schedule.The results indicated that：in the same fertilization conditions，plant height and leaf area index under the high irrigation treatments（irrigation quota for 900 m3 / hm2）were significantly higher than the low level treatments（irrigation quota for 600 m3 / hm2），especially during the jointing stage.The yield and starch of high irrigation treatments were also significantly higher than low level treatments and CK，which showed that high irrigation treatments could significantly improve the growth index，while the result of water use efficiency was quite the reverse.In the same irrigation conditions，there were no significant differences among different level fertilizer on growth indicators and yield.Overall，Treatment ABD（irrigation quota for 900 m3 / hm2，amounts of fertilization for 30 kg/hm2），taking into account all kinds of indexes，can not only economize on fertilizer，but also ensure the product output.
