He Xiang Zheng, He‐Ping Li, Song Zhang, Jian Cheng Zhang

Abstract

Optimization irrigation schedule can effectively improved the water use efficiency and the crop yield, and it uses the ISAREG model to study the optimization irrigation schedule of winter wheat based on the actual field test data in Hetao Irrigation District. The results showed that: the problems of irrigation quota and irrigation time are unsuitable through analyzed the actual irrigation schedule by calibrated and verified parameters; the optimization irrigation schedule of winter wheat is obtained on the basis of combines design different irrigation quota and irrigation time for the water requirement characteristics.
