From wheat and corn in the north to rice and tea in the south, and fruits in the west and specialty agricultural products from the eastern coastal areas, the rich variety of crops not only meets domestic demand but also secures a place in the international market. However, with the increasing prominence of issues such as climate change and environmental pollution, agricultural production faces unprecedented challenges. Therefore, conducting relevant research is crucial to deeply explore the specific impacts of different environmental factors on crop growth and to formulate more scientific and rational agricultural management measures. These studies cover multiple aspects, from soil quality and water conservation to climate adaptability, aiming to find ways to increase crop yield and enhance crop resistance.
