- Abstract
Objective:To research the dynamic changement laws and balanced regulation of air and water between man and plant in inclosed system to provide theoretical support for the construction of CELSS.Methods:Man-plant compositive test was processed using the CELSS compositive test platform in which 4 kinds of plant were grown(Lactuca sativa L var.Dasusheng,Lactuca sativa L var.Youmaicai,Gynura bicolor and Cichorium endivia L)to exchange material with 2 men.In the test the environment was monitored and material flow was measured.Results:The dynamic changement laws and balanced regulation of air and water between man and plant in inclosed system was mostly mastered.The material closure degree of air,water and food reached 100\%,90\% and 10.2\% respectively with the whole system closure degree up to 95.1\%.Meanwhile,it was proved that 13.5 square meter of plant could satisfy the demand of one person for oxygen in the system,the energy efficiency ratio of which reached 59.56g/(kW*m2*day)matching advanced world level.Conclusion:A stable material flow balance was established between 2 men and the plant.The interaction was realized of man,plant and environment in inclosed system,which is of great significance to the advancement of long-term manned environment control and life support technology of China.
