Abstract: The experimental results showed insignificant difference in the ear number per unit area and grain yield of winter wheat between the traditional irrigation-optimized fertilization, optimized irrigation-traditional fertilization, optimized irrigation-optimized fertilization, optimized irrigation-optimized fertilization with crop residues, and traditional irrigation-traditional fertilization|the greatly reduced grain number per ear and significantly heavier weight of 1 000 grains of the optimized irrigation-optimized fertilization and optimized irrigation-optimized fertilization with crop residues|the significantly higher nitrogen use efficiency of the traditional irrigation-optimized fertilization, optimized irrigation-optimized fertilization and optimized irrigation-optimized fertilization with crop residues|and indistinct difference in water use efficiency between the five treatments.
