In order to improve the utilization rate of agricultural irrigation water, according to the agricultural irrigation water use, two-steps irrigation was used. The strategy of first stockpile water and then irrigation was applied. Before irrigation every time, in accordance with the DTW-ILC algorithm, the irrigation water was calculated and then stored in the irrigation tank. The calculated irrigation water stored in pool was modified repeatedly close to the actual water consumption in agricultural irrigation. At the same time, the next irrigation water stored in the reservoir could be useful for preventing anhydrous irrigation. The simulation results showed that the actual water use in agriculture irrigation could be tracked well after several times of irrigation process.
