摘　　要：利用热扩散茎流测定系统(TDP)对渭北高原矮化红富士树干液流进行长期定点定位观测,结果表明:苹果树各月平均日蒸腾速率变化规律除5、6、7月表现为双峰曲线外,其余月份基本呈现单峰曲线趋势。各月平均日蒸腾量存在差异,7月份最大,1月份最小。一年中,不同施肥处理的红富士苹果树蒸腾量在5-10月表现为施95kg有机肥的最大,其次是施有机肥150kg,再次是施有机肥40kg,不施肥的最小,其他月份影响较小。Stem sap flow dynamics of dwarfing Fuji apple tee on the Weibei plateau were studied by means of thermal diffusion stem sap flow measurement system （TDP）. The results showed that each month＇s aver age transpiration rate changed in the trend of single peak curve in addition to double peak curve in May, June and July. The monthly average daily transpiration was quite different, the maximum one was in July while the minimum one was in January. Different treatments on transpiration showed that in the May to October, the maximum one was in the treatment of applying the organic fertilizer 95 kg, followed by 150 kg, and 40 kg, the smallest one was for the no fertilizer. No influences were found in other months.
