研究红萍载人供O_2特征,为红萍生物部件进行系统总体地面模拟试验及空间应用奠定基础,构建了受控生态生保系统密闭试验舱和红萍栽培装置,在“红萍-鱼-人”共存情况下,测定密闭舱内O_2,CO_2浓度的变化.试验结果显示,单位重量的鱼耗O_2量为0.0805～0.0831 L·kg~(-1)·h~(-1),排放CO_2量为0.0705～0.0736 L·kg~(-1)·h~(-1);试验志愿者耗O_2量19.71 L·h~(-1),呼吸释放CO_2量18.90 L·h~(-1).人工光照保持7000～8000 lx条件下,红萍的光合作用与人和鱼的呼吸作用相辅相成,舱内O_2,CO_2浓度趋于平衡.密闭舱内CO_2浓度升高对促进红萍群体净光合效率有明显效果,红萍光合放O_2能力很强,能有效促使密闭舱内O_2,CO_2浓度朝着有利于人生存的环境方向平衡,进而验证了红萍的空间应用前景.
This paper studied the characteristics of Oxygenae officinalis for O 2, laid the foundation for systematic total terrestrial simulation experiment and spatial application of the biological components of Oxya chinensis, and built a closed laboratory of controlled eco- The results showed that the amount of O_2 per unit weight of fish consumed was 0.0805-0.0831 L · kg -1 · h -1, The amount of CO_2 was 0.0705 ~ 0.0736 L · kg -1 · h -1. The volunteers consumed 19.71 L · h -1 of O_2 and 18.90 L · h -1 of CO_2 ) Under artificial light conditions of 7000-8000 lx, the photosynthesis of Rhodiola rosea complemented with the respiration of human and fish, and the concentration of O_2 and CO_2 in the cabin tended to balance.The increase of CO_2 concentration in the airtight capsule could promote net photosynthesis The efficiency of red rhizome is very high. It can effectively promote the balance of O_2 and CO_2 concentrations in airtight compartments toward the environment conducive to human survival, and thus validate the spatial application prospects of red soaps.
