美国、英国等发达国家在20世纪60、70年代中期,曾经放置高空气球和利用“阿波罗”号飞船搭载种子,在经历了太空飞行的玉米种子发育成的植株中,观察到生长发育不正常及叶片上出现黄条斑的现象。美国在 NASA报告中记载航天种子与地面相比,出现营养层和表层多孔、微量元素等发生变化,这证明卫星搭载空间环境对 In the 1960s and 1970s, developed countries such as the United States and Britain placed high-altitude balloons and used “Apollo” spacecraft to carry seeds. Growth and development were observed in plants that had undergone space flight of corn seeds Abnormal and yellow patches on the leaves of the phenomenon. In the NASA report, the United States recorded that astronautic seeds showed changes in nutrient layer, superficial porous layer and trace elements as compared with the ground. This proves that the satellite is equipped with space environment
