The Yucheng Comprehensive Experiment Station (YCES) of Chinese Academy of Sciences (CAS) is located at the irrigation district of the Yellow River Basin in the Huang-Huai-Hai Plain, also called North China Plain. Physiognomy is characterized as hinterland covered mainly by fluvo-aquic soil (Fluvisol or cambisal) and salinized fluvo-aquic soil in the Yellow River Alluvial Plain. This region is dominated by warm-temperate semi-humid monsoon climate with ample energy and water resources. Historically, natural disasters such as drought, waterlogging, salinization, and wind erosion frequently occurred, resulting in vulnerable ecological environment and low grain production. Integrated improvements and managements were deployed in last several decades, and this region has become suitable for planting winter wheat, corn, cotton, and soybean with high yields in the Huang-Huai-Hai Plain.
