| Abstract: | The effect of four kinds of irrigated methods on the water-saving of rice were studied. The optimum irrigated method was the spring irrigation. The largest amount water was irrigated from the spike formation stage to the heading period. The relation between growth rate of the rice and the amount of irrigation water was negative . |
