| Abstract: | This paper presents, as a result of investigation conducted in Haizi Reservoir Irrigation Area by Chinese and Japanese experts, the method of measuring the characteristic value of soil moisture; the drawing up of soil moisture curve and its application; the application of tensiometer observation value; the method of calculating water-saving irrigation quota and intermittent days between two irrigations. The water-saving irrigation scheduling is worked out for various crops. This water-saving irrigation scheduling can save water by over 40% compared with the traditional irrigation scheduling. |
