摘要: The objectives of this study were to investigate the applicability of the DNDC model under long-term discontinuous fertilization (three years of fertilization followed by three years of no fertilization) in the winter wheat-summer maize rotation cropping system, and to analyze the effects of long-term fertilization and straw return on soil organic carbon (SOC) and crop yields and to optimize the ratio of straw incorporation to fertilization rate. A 30-year (1981-2011) long-term experiment was conducted at the Hengshui
