What's the difference between aerospace vegetables and ordinary vegetables? What is the difference between planting, what should be paid attention to, and what are the requirements for the environment? Vegetable seeds are carried into space by spacecraft and returned to earth for reproduction. The vegetables planted are called "space vegetables" or "space vegetables". Vegetable seeds were taken into space. Due to the change of environment, the internal genetic structure of seeds may or may not change. If it is changed, it is equivalent to obtaining a new variety, perhaps with higher yield and larger shape or vice versa. After returning to the earth, we still planted experiments according to the conventional methods, and constantly observed and adjusted them, achieving the scientific and technological goals.
