摘　　要：[目的]鉴定大枣各生育期气候条件。[方法]根据大枣各个生育阶段的气象指标,分析当地气候资源的利弊程度。[结果]温度条件是朝阳地区种植大枣的主要限制因子。朝阳南部地区热量充足,各生育时段的热量条件较好地满足生理指标的要求,适宜栽植大枣;而北部地区大枣生育关键时段的温度低于临界温度指标,不适宜栽植大枣。朝阳地区水分条件基本满足大枣生长发育需求。朝阳地区大枣生产气候优势是光照充足和温度日较差大。[结论]朝阳南部地区是适宜生产优良品质大枣产区。[Objective] The aim was to identify the climate conditions of jujube in each growth period.[Method] According to the climate indexes of jujube in each growth period,the advantages and disadvantages of local climate resources were analyzed.[Result] The temperature is the main restricted factor for jujube planting in Chaoyang Region.Heat resource is adequate in south of Chaoyang Region,which satisfy demands of physical index in each growth period and appropriate for jujube planting;while in north area,the temperature is lower than critical temperature index in key growth period,which not appropriate for jujube planting.Moisture condition in Chaoyang Region basically met the growth demand of jujube.The advantages of Chaoyang Region are enough light and diurnal temperature range.[Conclusion] The south of Chaoyang Region is appropriate for planting fine quality jujube.
