| Abstract: | To study the characteristics of soil water resources and the relationship between crop water consumption and soil water can effectively instruct increasing soil water amount, lessen irrigation amount, heighten water use efficiency in agricultural water use, and then save water in agriculture. Several aspects about soil water resource use in agricultural water-saving were introduced as follows: the calculation of soil water resource quantity, dynamic laws of soil moisture, effectiveness of soil water and water requirement and consumption laws of crops. |
