The ability to generate O2 and absorb CO2 of several co-cultured vegetable plants in an enclosed system was studied to provide theoretical reference for the future man-plant integrated tests. Four kinds of salad plants (Lactuca sativa L. var. Dasusheng, Lactuca sativa L. var. Youmaicai, Gynura bicolor and Cichorium endivia L.) were grown in the CELSS Integration Test Platform (CITP). The environmental factors including O2 and CO2 concentration were continuously monitored on-line and the plant biomass was measured at the end of the test. The changing rules of O2 and CO2 concentration in the system were basically understood and it was found that the O2 generated by the plants could satisfy the respiratory needs of 1.75 persons by calculation. It was also found that the plants could absorb the CO2 breathed out by 2 persons when the light intensity was raised to 550 mmol m−2 s−1 PPF. The results showed that the co-cultured plants hold good compatibility and excellent O2-generating and CO2-absorbing capability. They could also supply some fresh edible vegetable for a 2-person crew.
