Winter Wheat Irrigation Scheduling in Different Hydrological Years Based on CROPWAT
Abstract：Aiming to research the different irrigation scheduling within different hydrological years, CROPWAT was used to analyze the irrigation scheduling of winter wheat in three different precipitation years based on weather data from 1951 to 2010. The results showed that the net irrigation quotas in three different hydrological years (drought, normal, wet) were 353.3 mm, 342 mm, 296.2 mm with full irrigation respectively. And the frequencies of winter wheat irrigation were 8, 7 and 6 separately. Moreover net irrigation quotas were 229.1 mm, 222.2 mm, 212.3 mm with the 4 specific dates of irrigation.
