Analysis of Water Use Efficiency and Benefit of Winter Wheat under Different Water and Fertilizer Coupling
The experiments of winter wheat under different water and-fertilizer coupling were conducted in watersaving .irrigation Experiment Center of Tianjin Agricultural University from October 2007- June 2008. Yields, water use efficiency (WUE) and benefit of winter wheat under different water and fertilizer couplings were studied. The results showed that: the yield, WUE and benefit of winter wheat are the highest under the medium water and fertilizer. Overfertilization affected the winter wheat yield; irrigation at jointing and seed filling stage made plants grow better, while moderate water shortage in the later growth stage have acer-tain role in promoting the yield formation. Therefore, in order to conserve resources, protecting environment, as while ensuring the winter wheat has good yields, medium irrigation and medium low fertilization should be used in Tianjin area.
