Abstract: The paper aims to study the relationship between variation characteristics and environmental factors of the liquid flow rate in Armeniaca vulgaris‘Kuchebaixing’under different typical weather conditions, and to investigate the effects on the liquid flow rate in tree trunk by different environmental factors. With Armeniaca vulgaris‘Kuchebaixing’as test material, we determined and analyzed the variation of the liquid flow rate in tree trunk from March to August. The results showed that the liquid flow rate in Armeniaca vulgaris‘Kuchebaixing’trunk changed more obviously in the sunny weather conditions while changed gently in the rainy days from month to month. The total solar radiation and air temperature were the main environmental factors which influenced the change of the liquid flow rate in Armeniaca vulgaris‘Kuchebaixing’tree trunk. In addition, there was a positive correlation between the total solar radiation, air temperature and the liquid flow rate.
