中文摘要：

采用大田试验研究养殖废水灌溉对作物-土壤系统各因子的影响。结果表明，灌水定额为900m^3／hm^2有利于产量的增加，灌水定额为600m^3／hm^2有利于水分利用效率提高。冬小麦叶水势随生育阶段的推移而减小，养殖废水处理的叶水势较清水处理的小。表层0～40cm为水分交替变化的敏感土层，随深度的增加，变化幅度减小。

英文摘要：

Field trials were conducted to study the influence of livestock wastewater irrigation on crop-soil system. The results showed that irrigation quota of 900 m^3/hm^2 is beneficial to yield increasing, and irrigation quota of 600 m^3/hm^2 is beneficial to water use efficiency increasing. Leaf water potential decreases with advancing growth stage. And the leaf water potential is less than clear water control treatment. The soil layer of 0-40 cm is the sensitive layer of soil water alternating changing. And the change of soil moisture decrease with increasing soil layers.
