- •
50-cm soil moisture has higher correlation with yield than surface layers.
- •
Soil moisture and reference evapotranspiration in autumn play the opposite role.
- •
Short-term drought in autumn and winter plays an important role in yield.
- •
The SPEI can achieve the highest correlation with winter wheat yield.
