Water consumption and use efficiency of winter wheat with swine wastewater irrigation
猪场废水灌溉对冬小麦耗水和水分利用效率的影响

Livestock wastewater irrigation is an important way to alleviate the problem of water shortage, especially in North China Plain. In this paper different treating stages of swine wastewater were used for wheat irrigation by the field experiment method. Soil water contents were monitored in each week. Water consumption and use efficiency (WUE) were analyzed with the precipitation and irrigation amount. The results showed that: Soil water storages and consumptions under different anaerobic quotas were in order of Manae>Hanae>Lanae and Hanae>Manae>Lanae, respectively. Soil water storages of different treating stages of swine wastewater irrigation were insignificant, and stable in range of 650 mm to 700 mm. WUE of different treatments followed by Manae>Lanae>Hanae and Tanae:gw1:5>Teco:gw1:5 >Tori:gw1:5>CK. Water consumption had significant correlations with irrigation quota, WUE and irrigation efficiency, respectively. Manae, Tanae:gw1:5 and Teco:gw1:5 were recommended as high WUE patterns of swine wastewater.
