Abstract: The main factors affecting wheat yield are irrigation water frequency and sowing date in wheat production in northwest Shandong province, but the regional irrigation water resources are scarce. In order to make the limited resources fully increase wheat yield, The experiment was designed and studied on irrigation times and sowing time of wheat. Three sowing periods and five irrigation modes were adopted in the experiment. The results showed that the effect of sowing date on wheat yield and water use efficiency was not significant, and irrigation was the main factor affecting wheat yield. The highest yield of irrigation was 3 times, followed by 2 times of irrigation, and the lowest of 1 time of irrigation, The more water is irrigated, the lower the water use efficiency is. According to the effect of yield and water use efficiency, it is suggested that winter wheat should be irrigated 3 times (dry year) or 2 times (high water year).
