针对任务周期长、距离远的长期载人深空探测,长期地外生存等任务要求建立受控生态生保系统,通过合适的植物部件利用当地资源进行空间作物生产。利用等效系统质量方法,比较了地球携带食物补给和受控生态生保系统植物部件就地生产两种补给模式的优劣。从受控生态生保系统角度讨论了主食、果蔬和蛋白质-脂肪等食物需求与植物部件设计的关系,对1~2年任务周期的深空探测飞行任务首先应配备小量蔬菜栽培装置。可以利用太阳光时,2年以上即可建立植物部件生产果蔬;15年以上方可生产粮食作物;而只能利用人工光源时,3.4年以上的深空探测任务才适合植物部件供应新鲜果蔬,而主食则需要76年以上。油料作物的空间生产在目前技术条件下不具备应用可行性。
For tasks such as long-term mission and long-term manned deep space exploration with long-term manpower and long-term survival beyond the earth’s surface, a controlled ecological life-support system is required to make space crop production by utilizing appropriate local plant resources through appropriate plant components. Using the equivalent system quality method, the advantages and disadvantages of two modes of in-situ production of the plant components of the Earth-borne food supplies and the controlled eco-health-care systems were compared. The relationship between staple foods, fruits and vegetables, protein-fat and other food requirements and the design of plant components was discussed from the perspective of the controlled eco-life insurance system. For a deep space exploration mission of 1 to 2 years, a small amount of vegetable cultivation equipment should be provided. Can use the sun, more than 2 years to establish the production of plant parts of fruits and vegetables; more than 15 years before the production of food crops; and can only use artificial light source, 3.4 years of deep space exploration mission is suitable for plant parts supply of fresh fruits and vegetables, The staple food you need more than 76 years. The space production of oil crops does not have the feasibility of application under the current technical conditions.
