Abstract To study the impact of different water‐nitrogen regulation modes on carbon cycle greenhouse tomatoes and determine optimal irrigation nitrogen application levels to enhance absorption minimize gas emissions. This employed three (100%, 80%, 60% ET0) (240, 192, 144 kg·ha −1 ), along with a control group (W1N1, i.e., 100% ET0‐240 ). Gas‐chromatography methods were used monitor CH 4 soil CO 2 emissions, while assessing dry matter, content, fixation capacity tomato organs throughout growth period. Additionally, system for evaluating net ecosystem budget facility was developed based primary productivity. Results indicated reduced emissions decreased application. Dry initially increased but then declined. The W2N2 (80% ET0‐192 ) treatment showed maximal values fixation, productivity (NPP), gross (GPP). Findings suggest positive under water conditions, indicating absorption. Specifically, outperformed others in absorption, highlighting its potential as an effective mode enhancing sequestration region.
