文摘
- •
HYDRUS can accurately simulate soil water dynamics in Populus tomentosa plantation.
- •
Soil water at different depths made different contributions to tree growth variation.
- •
Monitoring the surface soil water provides a robust means for predicting tree growth.
- •
rθ in the 0–30 cm soil layer should be maintained above 0.7 to minimize growth loss.
