酸枣树干液流速率与环境因子的关系
Relationship between stock sap flow rate of Zizyphus acidojujuba Hu and environmental factors
摘要
Abstract
Zizyphus acidojujuba Hu, which is the typical shrub of northern China, was selected to determine the stock sap flow by TDP. The correlation between sap flow rate and environmental factors was analyzed and the regression models between them in different weather conditions were constructed by SPSS. The results showed that in different weather conditions, the sap flow rate was influenced by each environmental factor with different levels. In sunshine, cloudy and rainy days, the most important environmental factors to stock sap flow rate were air temperature, solar radiation and rainfall, respectively. In different weather conditions, the environmental factors brought into model were very different. The simulation model in sunshine and cloudy was nice but was not so good in rainy day.关键词
