摘  要：
【目的】研究不同环境因子对平欧杂种榛茎流速率的影响,分析树体茎流速率变化,为榛树的水分管理提供理论依据。【方法】以平欧杂种榛新榛1号(84-254)为材料,利用FLGS-TDP插针式茎流计连续监测平欧杂种榛的茎流速率,分析平欧杂种榛茎流速率的变化规律及其与环境因子的相关性。【结果】平欧杂种榛在不同月份相同天气和相同月份不同天气下,茎流速率均呈倒"U"型变化曲线。在不同天气下各月的茎流速率均表现为晴天>多云>阴天,5月茎流速率变化幅度最小。5月晴天和阴天天气下,影响茎流速率的主要环境因子为大气温度,而多云天气下为太阳辐射,6、7和8月影响茎流速率的主要环境因子为大气温度。【结论】晴天茎流速率大于阴天和多云天,7月茎流速率变化幅度最大。大气温度和太阳辐射是影响平欧杂种榛茎流的主要环境因子。

摘  要：
【Objective】 To explore the effects of different environmental factors on stem flow rate of Corylus heterophylla × Corylus, and to understand the change of stem flow rate of Corylus heterophylla × Corylus, in the hope of providing theoretical basis for water management of hazelnut. 【Methods】 The stem flow rate of Corylus heterophylla × Corylus New Hazel 1(84-254)was continuously monitored by FLGS-TDP needle insertion stem flow meter. and the variation of stem flow rate of Corylus heterophylla × Corylus and its correlation with environmental factors were analyzed. 【Results】 The stem flow rate of Corylus heterophylla × Corylus showed inverted "U" curve in the same weather and different weather in the same month. The stem flow rate in each month under different weather conditions was sunny day > cloudy day > cloudy day, and the variation range of stem flow rate in May was the smallest. The main environmental factors affecting stem flow rates in sunny and cloudy weather in May were atmospheric temperature, while in cloudy weather, they were solar radiation. The main environmental factor affecting stem flow rates in June, July and August were atmospheric temperature. 【Conclusion】 The stem flow rate in sunny days was higher than that in cloudy and cloudy days, and the variation range of stem flow rate was the largest in July. Atmospheric temperature and solar radiation are the main environmental factors affecting the stem flow of Corylus heterophylla × Corylus.
