植物在外层空间的反应如何?哪些植物适宜在空间生长,可为未来的宇航员在漫长的空间探险中提供食物?为了解决这些问题,苏联正在进行这方面的研究,并在其空间站-礼炮号上进行了许多试验。试验是在礼炮号的植物园里进行的。在这块小小的园地里,宇航员们精心种植了小麦、洋葱、西红柿、苔鲜,甚至还种植了郁金香。开始,由于失重的原因,这些植物的根部有时“漂浮”在空间,而茎部却伸入土中。显然,这样是长不好的,有的甚至萎缩死亡了。科学家们对此作了
How do plants react in outer space? Which plants are suitable for growing in space and provide food for future cosmonauts in the long space expedition? In order to solve these problems, the Soviet Union is carrying out research in this respect and conducting research on its space station, Many tests have been conducted. The experiment was conducted in the Salyut Botanical Garden. In this little garden, astronauts carefully planted wheat, onions, tomatoes, moss, and even planted tulips. Initially, due to weightlessness, the roots of these plants sometimes “float” in space, while the stems protrude into the soil. Obviously, this is not good long-term, and some even shrink and die. Scientists made this
