To clarify the effects of increased density and reduced nitrogen on greenhouse gas emission in double-season paddy fields under the water-saving and simple cultivation mode, we used Luliangyou 996 (early rice) and Fengyuanyou 299 (late rice) as materials to collect greenhouse gas by closed static box method, monitored the dynamics of CH and NO emissions from different combinations of increased density and reduced nitrogen for early and late rice, and explored changes in cumulative CH and NO emissions, global warming potential (GWP) and greenhouse gas intensity (GHGI) as affected by different combinations of increased density and reduced nitrogen from double-season rice fields. The results showed that the cumulative emissions of CH and NO from different combinations were significantly different. Compared with the control (CK), cumulative CH emission, GWP and GHGI in the two seasons decreased by 50.

Methods: A total of 101 patients undergoing LCCR were randomly divided into three groups: control (=34), TAP (=35) and TEAS+TAP (=32). Conventional perioperative anesthesia management of the 3 groups was performed according to the ERAS guidelines.
To provide support for the efficient use of water and fertilizer technology to double-season rice cultivation, water and fertilizer coupling mode was applied in this research, including two irrigation methods and four N levels. The irrigation methods were flood irrigation and intermittent irrigation, while four N levels were high-N, middle-N, low-N and none-N. Field experiment was conducted to study the effect of water and fertilizer coupling mode on CH4 and N2O emission.
