Abstract：In response to the rare persistent drought affecting wheat fields in the Yancheng region of Jiangsu from winter 2024 to spring 2025,this study combined field investigations,in-situ observations,and literature analysis to systematically investigate the effects of drought stress on various growth stages of wheat and response strategies.The results showed that prolonged drought significantly negatively impacted wheat growth and development,mainly resulting in uneven seedling growth,a substantial decrease in effective tillering,and ultimately a decline in grains per spike.Comprehensive comparison of drought resistance techniques showed that the optimal timing for irrigation was during the wheat jointing stage.In terms of irrigation methods,the order was sprinkler irrigation＞watering irrigation＞furrow irrigation＞flood irrigation＞soaking irrigation.The appropriate irrigation amount should be controlled between 40 mm and 60 mm.The findings of this study can provide concrete technical guidance for drought resistance,and offer valuable references for drought management in wheat fields within Jiangsu Province and similar ecological areas.
