Soil temperature and humidity
In order to compare the water demand between the two species analyzed, soil temperature and humidity meters (Watch Dog 1200, USA) were placed in the 10-cm soil layer in the four habitats on September 1, 2017; the meters were removed on October 2, 2018. Each temperature and humidity meter recorded data every hour. The data from October 1, 2017 to September 30, 2018 were used to analyze the annual conditions. Three temperature and humidity recorders were placed in three individual sites for each habitat, and a total of 3 (repetition) × 4 (habitat) = 12 recording units were set up.
The data for temperature and humidity were divided into four parts, namely the winter season (October 1, 2017–March 31, 2018; WP), seedling period (April 1–May 31, 2018; SP), growing period (June 1–July 31, 2018; GP), and flowering and fruiting period (August 1–September 30, 2018; FFP). The average temperature and humidity data for each period were calculated.
