Crop yields were significantly increased by straw mulching over both cycles, and by plastic film mulching in cycle 2. Both straw and film mulching significantly increased soil CO2 emission over both cycles. Patterns of soil N2O emissions under straw or film mulching are not consistent. Both straw and film mulching significantly decreased annual GHGI. Straw mulching is recommended in Loess Plateau, China.
