美国宇航中心已经采用最先进的无土栽培技术,生产人类在太空中生活必需的食物获得成功。采用生物技术培育的特殊品种,与高度集约的无土栽培方法,现在已经能做到小麦从种到收共6周时间。根据目前的研究进展,宇宙航行在失重状态下,植物生长没有“向性”,幼苗的根是“向下”生长,而不是朝着阳光“向上”生长。同时要解决在失重状态下营养液的输送问题,因为在失重状态下,营养液会“飞”起来,使植物根系无法吸收利用。现已研究出将萌发的种子置于
The United States Aerospace Center has adopted state-of-the-art soilless cultivation techniques to make the food necessary for the life of mankind in space successful. The use of biotechnological cultivation of special varieties, and highly intensive soilless cultivation methods, wheat can now be done from planting to harvest for a total of 6 weeks. According to the current research progress, under the condition of weightlessness, astronautism has no “tropism” in plant growth, and the roots of seedlings grow “downwards” rather than “upwards” toward the sunlight. At the same time to solve the weight loss in the state of nutrient solution delivery, because in the state of weightlessness, nutrient solution will “fly” together, so that plant roots can not be absorbed. It has been studied to place germinated seeds
