Table 4. Precipitation treatments differences for soil moisture, soil temperature and soil CO2 flux over the whole experimental period.
| Precipitations | R50 | R100 | R150 |
|---|---|---|---|
| Mean soil moisture (%) | 8.1 ± 2.3 b | 12.9 ± 2.9 ab | 13.4 ± 3.5 a |
| Mean soil temperature (°C) | 19.2 ± 1.3 a | 18.9 ± 1.1 a | 18.7 ± 1.1 a |
| Mean soil CO2 flux (µmol CO2 m−2 s−1) | 2.2 ± 0.4 b | 3.6 ± 0.8 ab | 3.9 ± 0.8 a |
Notes.
Values are the mean ± standard error (n = 3). There are three precipitation treatments, and each treatment has three replicates. Sampling was conducted 11 times during the growing season. Different letters show significantly different between precipitation treatments (P < 0.05).
