To explore the stable yield of forage oats under future climate change conditions and to capture more climatic resources after the main crop season, based on the Agricultural Production Systems Simulator (APSIM) crop model, the sowing dates were adjusted to different degrees of advancement at six locations in northern Shanxi. The responses of forage oat yield and climatic resources to sowing date adjustments under different climate scenarios were simulated and evaluated. The results showed that under future climate warming, moderate early sowing (advanced by 10 days) can increase the climatic resources available after harvest and before the first frost, including accumulated thermal time (1 200-1 800 ℃), precipitation (55-188 mm), and solar radiation (861-1 523 MJ·m-2), without significantly reducing the main-season forage yield. Consequently, the utilization efficiency of climatic resources was improved. Early sowing has a limited direct effect on forage yield, it demonstrates excellent performance in terms of forage yield stability and resource enhancement. Overall, appropriately advancing sowing dates is an effective field management strategy for adapting to climate warming and enhancing resource use efficiency.
