QIAO Dong-mei1,2,QI Xue-bin1,FAN Xiang-yang1,DAI Zhi-guang3,LI Ping1,HUANG Zhong-dong1,ZHAO Zhi-juan1(1.Farmland Irrigation Research Institute,Chinese Academy of Agricultural Sciences,Xinxiang 453003,China;2.Graduate School of Chinese Academy of Agricultural Sciences,Beijing 100081,China;3.Hebei Engineering and Technical College,Cangzhou 061001,China)  
Field trials were conducted to study the influence of livestock wastewater irrigation on crop-soil system.The results showed that irrigation quota of 900 m3/hm2 is beneficial to yield increasing,and irrigation quota of 600 m3/hm2 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.
