In the hilly areas of southern China, uplands and paddies are located adjacent to each other. Using rice straw as mulch for upland soil may improve crop production and partially replace chemical fertilizers, which may mitigate N2O emissions. A field experiment was conducted to investigate the potential of rice straw mulching for mitigating N2O emissions and increasing crop production. The treatments included no mulching (CK), 5000kgha−1 of straw mulching (SM5), and 10,000kgha−1 of straw mulching (SM10). Moreover, all the treatments received e...
