摘　　要：为研究‘库车白杏’树干液流速率在不同月份典型天气条件下的变化特征及其与环境因素之间的关系,探讨不同的环境因子对树干液流速率变化的影响,以‘库车白杏’为试材,对其树干液流在3—8月的变化情况进行测定与分析。结果表明:‘库车白杏’树干液流速率在不同月份晴天天气条件下变化较为明显,而在阴雨天变化趋势比较平缓;对其树干液流速率产生影响的环境因子主要是太阳辐射以及空气温度,并且太阳总辐射和空气温度与液流速率均呈正相关。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.
