摘　　要：分析陕北、渭北地区旱地苹果全年和不同月份气候干湿状况的地区分异 ,研究不同分区典型县区苹果的降水产量积分回归函数 ,探讨其降水对产量的影响规律 ,确定了不同分区苹果的最佳补充灌溉时期。Based on analysis of the regional feature of weather and soil moisture deficiency, the integeral function of production typical counties and the effects of rainfall on apple production in different districts were studied. The optimal compensation irrigation periods of apple orchard in different districts were determined.
