中文摘要	采用包裹式茎流计持续测定枣树茎流速率,并结合HOBO小气候仪同步获取太阳辐射强度、温度、空气相对湿度以及风速等气象数据,研究不同天气条件下枣树茎流速率的变化规律及其与气象因素之间的关系。结果表明:枣树茎流连续日变化呈现明显的规律性,白天的茎流速率明显大于晚上。茎流速率日变化曲线晴天为典型的宽型单峰曲线,阴雨天为不规则的多峰曲线。2种天气条件下,枣树日累积茎流量变化过程均呈现明显的S形曲线,且晴天的日累积茎流量明显高于阴雨天。枣树茎流速率与气象因子关系密切,2种天气条件下,茎流速率与太阳辐射强度相关性最强,与风速相关性最弱,利用多元回归的方法建立枣树茎流速率与气象因素的相关性回归模型,经过回归系数和相关系数检验,晴天回归系数为0.901,阴雨天为0.803,均达到极显著水平。
英文摘要	The package type stem flow meter was used for continuous determination of the jujube tree stem flow rate,and the HOBO microclimate meter synchronously determined the solar radiation, temperature,air humidity and wind speed and other meteorological data, so as to study the change rule of jujube tree stem flow rate under different weather conditions and its relationship with the meteorological factors. The results indicated that jujube stem flow consecutive diurnal variation showed significant regularity,day sap flow rate was significantly greater than that in the evening; stem flow diurnal variation curve in sunny day was the typical wide single peak curve, in rainy days was irregular multimodal curve; under two weather conditions, the change of day cumulative sap flow rate of jujube showed a significant Sshaped curve,and the stem flow accumulation was significantly higher in sunny day than that in rainy days; under two weather conditions, the relationship between jujube stem flow rate and the meteorological factors was close, stem flow rate had the strongest correlation with solar radiation and the weak correlation with wind speed,using multiple regression method to establish the correlation regression model of jujube stem flow rate and meteorological factors, the regression coefficient was 0.901 in sunny day,and 0.803 in rainy day,which all reached significant level.
