[Effects of Plastic Film Mulching Patterns and Irrigation on Yield of Summer Maize and Greenhouse Gas Emissions Intensity of Field].

In order to evaluate the effect of different treatments on yield and greenhouse gas emissions during the summer maize growing season, a two-year film mulching experiment was conducted in 2014 and 2015. In this experiment, the two main experimental factors were rainfed treatment (R) and irrigated treatment (I), and the secondary experimental factors included control treatment (CK), half film mulching treatment (HM), and full film mulching treatment (FM). The emissions of soil greenhouse gases (CO, CH, and NO) were monitored using a static opaque chamber and chromatography method.
