In order to explore the response of growth physiological characteristic and yield of rice to the water consumption process in black soil region, the experiment was carried out by lysimeter at the rice irrigation experiment station of Heilongjiang Province in 2017. The U7（7.6） experiment was conducted to analyze the effects of water consumption at each stage on growth physiological characteristic and yield of rice. The results showed that the water consumption intensity during the growth period of rice generally showed a trend of rising firstly and then decreasing, the maximum water consumption intensity at headingflowering stage was 5.66mm/d; the maximum water consumption percentage during the whole tillering stage was 43.98%, which tended to be stable after the headingflowering stage. The water consumption at the late tillering stage had the greatest influence on dry matter weight of rice leaf; the dry matter weight of stem sheath and spike had significant response to the water consumption at jointingbooting stage and headingflowering stage (P<0.01); the water consumption at the midtillering stage and late tillering stage showed a greatest positive and negative effects on dry matter weight of root, respectively; except for the early tillering stage, the effect of water consumption from the midtillering stage to headingflowering stage on the amount of bleeding of root was represented as ET2, ET3, ET4 and ET5; the water consumption at the midtillering stage, jointingbooting stage and headingflowering stage had a positive effect on Gs and Tr （P<005）; the water consumption at the early tillering stage showed a negative effect on Tr （P<0.05）; except for ET1, the effect of water consumption from the midtillering stage to headingflowering stage on Ci and Pn were represented as ET5, ET2, ET4, ET3 and ET2, ET5, ET4 and ET3，respectively. The λ at the midtillering stage, jointingbooting stage and headingflowering stage were 0.120, 0.244 and 0.252, respectively, and the water consumption of these three stages had more significant effects on rice yield. The research result would provide a basis for making watersaving irrigation of rice in black soil region.
