Measurement of soil temperature and moisture
In parallel with net ecosystem exchange measurements, we measured soil
temperature at 10 cm depth in the leaf chamber with two TP3001
electronic thermometers. At the same time, we collected 10 cm soil
samples using a 2.5 cm diameter × 10 cm high soil auger, which we
collected in an aluminum box, weighed and recorded the wet mass, and
then dried at 105 ℃ for 24 h to weigh the dry mass and then calculate
the mass water content.
