Vegetables eaten by astronauts don't need soil.

Vegetables eaten by astronauts don't need soil. It does not depend on the natural environment, so it only takes 35 days for vegetables to be sent to the astronauts' table.

Astronauts can't be careless in their diet and daily life on earth. In order to better protect their daily diet, Jiuquan Satellite Launch Center established an artificial light and vegetable factory to directly supply pure fruits and vegetables to astronauts before going out to war. The whole process of sterile culture mode, so that all personnel entering the vegetable factory wear protective clothing, and then layers of disinfection.

Advantages of astronaut's vegetable cultivation methods

The first word is to control plants with artificial light; Second, its environmental control can achieve appropriate temperature and humidity; The third is the nutrient solution supply system. When there is a lack of nutrient solution under the plant, it will automatically replenish it. Our staff will only monitor in the nutrient solution room to see if there is a lack of nutrient solution.

Every day, the staff will check the pH value, EC value and growth status of vegetables. The whole factory simulates the natural environment, but it breaks through the limitations of the natural environment. This green factory not only ensures that astronauts can eat high-quality vegetables and fruits in groups, but also enriches the food baskets of scientific and technological personnel and workers' families in peacetime.
