干旱区枣树蒸腾规律及其与气象要素的关系
Relationship between jujube trees transpiration rule and the weather factors in arid areas
摘要
Abstract
In order to research the relationship between jujube trees transpiration rule and the weather factors, using the Dynagage wrap measuring sap flow meter to collect the data, and combined with a small automatic weather station witch can simultaneously measure the meteorological data, analyzed the relation of jujube trees diurnal variation of transpiration rate with the meteorological factors. The results show that different types of weather, the diurnal variation of transpiration rate is significantly different. During sunny weather, the transpiration rate curve showed a single peak curve trend, and the transpiration rate of more than 2000 g/h lasts long duration. In cloudy and rainy weather, the transpiration rate is relatively small, and the transpiration rate curve mostly showes in the form of multi-peak curve. The diurnal transpiration rate gradually increases from May, June and July to reach the maximum value in a year, then gradually reduces. These meteorological factors such as air temperature Ta , relative humidity RH , solar radiation Rn and rainfall P associate a higher relation with the transpiration rate Tr . But the wind speed is less relevant with the transpiration rate Tr and do not significantly affect the results. The main weather influence on the transpiration rate is solar radiation.关键词
