This research about the effects of water stress at different growth stages on the crop growth traits has a practical significance in guiding water-saving irrigation. The box test method is adopted to test the water stress of winter wheat at different stages, observe the plant height, leaf area and yield, and analyze the water use efficiency under the condition of water stress. The results show that the water stress in each growth period will play an inhibiting role in the plant height and leaf area of winter wheat; the water stress duration at a single stage is relatively short, and rehydration crop has a certain compensatory growth without making a big difference; the continuous water stress stage plays a significantly inhibiting role in the plant height and leaf area.; water stress has a largest effect on the plant height in the elongation period; the heading period suffers from water stress, so the leaf area decreases rapidly; water stress at a single stage in the appropriate period can increase water use efficiency. Regulated deficit irrigation can reduce luxury water consumption, which has a little effect on the yield and plays a guiding role in water saving and stable yield.
Key words: winter wheat / growth period / water stress / plant height / leaf area / water use efficiency
