摘要： Carbon dioxide (CO2) is one of the important factors affecting vegetable yield in controlled environments. This study used cucumber as an experimental material to investigate the effects of hanging different amounts of CO2 generation bags (CGBs) on the growth of temperature-loving vegetables under facility soil cultivation. CGBs of three different densities were set up: no application (TC), eight bags/265 m(2) (T1), and sixteen bags/265 m(2) (T2). The results showed the following: (1) Hanging CGBs at different densities significantly impacted indoor CO2 concentration. Light, temperature, and humidity also affected CO2 concentration to a certain extent. (2) The application of CGBs improved cucumber growth, photosynthesis, and quality-related indexes, resulting in a 28.9% increased yield compared to the control group. (3) The economic benefits of CGB application in each group were analyzed, revealing the economic benefits of high-density CGB cultivation on solar greenhouse cucumber. This study explored a low-cost and effective CO2 generation application mode.
