variation of poplar sap flow and its response to meteorological factors
abstract
the purpose of this paper was to analyze the changes of poplar sap flow, to explore
the meteorological factors affecting the changes of poplar sap flow and their response
laws, so as to provide a theoretical basis for the follow-up study on the improvement of
poplar living tree and the rising mechanism of its liquid medicine. the sap flow rate of
poplar was measured by flow 32a-1k wrapped sap flow meter, and meteorological
factors were measured simultaneously by solar meter and temperature and humidity
meter. the results showed that there was a significant positive correlation between
poplar stem velocity and solar radiation intensity and air temperature, but a negative
correlation with air relative humidity. therefore, the influence degree of different
meteorological factors on poplar sap flow rate is different.
