| 摘 要： | 红萍作为空间站受控生态生命保障系统中的生物部件,可望为航天员提供O_2和新鲜蔬菜并吸收CO_2.研究红萍湿养栽培供O_2装置,旨在建立地面非生物部件,满足模拟研究的需要.介绍了所研发装置及关键部件的结构特点和工作原理.通过红萍湿养板内湿养栽培介质的结构功能设计,在蓄水保水基质层内部配置具有毛细作用的渗水管路,介质始终保持整体湿润而表面无明水状态,为红萍扎根稳固、营养吸收和生长繁殖创造条件.水压试验确定了渗水管路的主要技术参数和闭合式红萍培养液输配循环系统的间歇循环周期.整机产出量试验结果表明,在层间距125 mm,整机红萍湿养面积6.3 m~2,超高亮度白色LED人工光源能耗152 W/m~2,红萍表面的光照强度6000～6500 lx,整机的红萍湿养产量、红萍放O_2量和吸收CO_2量相应大幅提高,装置各项性能指标均达到设计要求.
