Chinese Journal of Ecology,1998,17(3):20-26.A twoyears' experiment was carried in the concrete troughs which can exactly control the water quantity . The results showed that the proper water saving irrigation patterns could regulate the water status internal the rice plants. The relative water content of leaves, especially the rate of free water to total water contents, under water saving irrigation were significantly higher than that of normal irrigation .The senescence of lower leaves delayed and the function time of photosynthetic source in reproductive stages increased too. The activity of root system at reproductive stages raised and the contradiction between high yield and early senescence of roots was coordinated. Enhancement of the dry matter accumulation in reproductive stages favored the grain yield development. Thus, the water saving irrigation resulted not only in water saving but also in high yield. An optimized irrigation pattern was discussed in the paper.
