摘　　要：利用1951—2010年的气象数据,采用CROPWAT模型对枯水、平水、丰水3个典型降水年冬小麦的灌溉制度进行研究。结果表明,3个不同的典型降水年充分灌溉净灌溉定额分别为353.3、342、296.2mm,灌水次数依次为8、7和6次;4次关键水条件下净灌溉定额分别为229.1、222.2、212.3mm。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.
