Effects of Climate Change on Wheat Yield and Nitrogen Losses per Unit of Yield in the Middle and Lower Reaches of the Yangtze River in China

Nitrogen fertilizer is one of the essential nutrients for wheat growth and development, it plays an important role in increasing stabilizing yield. Future climate change will affect growth, yield, since also alter nitrogen cycles farmland. Therefore, further research needed to understand response yield losses during cultivation. In this study, we investigate wheat-producing region middle lower reaches Yangtze River China, leading areas, by employing a random forest model using records from agricultural meteorological observation stations spatial data on application rate, losses. The predicts winter based CMIP6 related environmental variables, under SSP126 SSP585 emission scenarios. results show that future (temperature precipitation changes) decrease 2~4% reduce total 0~5%, but other increase 0~5% N leaching per unit 0~10%. study can provide theoretical basis reference optimizing rates, reducing cultivation conditions.
