- Water-nitrogen use, rice growth and yield dynamics in cold regions of Northeast China: A five-year study (2025) · Agricultural Water Management · cited 3× · doi
Rice production in the cold region of Northeast China is highly sensitive to irrigation regimes and inter-annual meteorological variations, but the long-term effects of traditional flood irrigation (TFI) and controlled irrigation (CTI) on rice growth, yield formation, water-nitrogen use efficiency, and grain quality remain insufficiently quantified.

Recent declines in the rice Multiple Cropping Index (MCI) have reshaped grain production and water dynamics across Southern China, yet their effects on production stability and watershed hydrology, particularly in subtropical hilly regions, remain insufficiently studied.
