The Shenzhou 14 manned spacecraft is approaching a space business trip. The astronauts should not be careless in their daily life on earth. in order to better ensure their daily diet, the Jiuquan Satellite Launch Center has established an artificial light vegetable factory to directly supply pure vegetables and fruits to the astronauts before the expedition**
The artificial light vegetable factory covers an area of 728 square meters. It was completed and put into trial operation in March 2021. It is never easy to plant green in the Gobi desert. This vegetable factory is not only green, ecological, but also full of science and technology. It is a real Gobi oasis.
CCTV reporter he Chun: this is the artificial light vegetable factory of Jiuquan Satellite Launch Center. Do you believe it? It doesn't need soil, nor does it depend on the natural environment. Vegetables can be sent to the astronauts' table in only 35 days. How did they do it? Today we will take a look with you.
The whole process aseptic cultivation mode makes all personnel entering the vegetable factory wear protective clothing, and then go through layers of disinfection and sterilization. When we enter the interior, we push the door open, and the fragrant air rushes to our faces.
CCTV reporter Hechun: What are you doing here?
Yuwenda, production personnel of the artificial light vegetable factory of Jiuquan Satellite Launch Center: this is our nutrient solution for refining seedlings. Control this nutrient solution in the seedling tray, and then the seeds, including the emergence rate, will be controlled very high.
Here, nutrient solution replaces soil, led plant spectrum replaces sunlight, and computer system automatically controls plant growth. No pesticides are used in the whole production process.
CCTV reporter Hechun: after refining and raising seedlings, small vegetable seedlings will be sent to the cultivation area, which is also the last link of vegetables.
Ruanxiang, head of the artificial light vegetable factory of Jiuquan Satellite Launch Center: compared with traditional agriculture, our artificial light vegetable factory has three advantages. The first is to use artificial light to control plants; The second is that it can reach an 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 supplement it. Our staff will only monitor it 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 plant simulates the natural environment, but it breaks through the limitations of the natural environment. This green factory not only ensures that the astronauts can eat high-quality vegetables and fruits, but also enriches the vegetable baskets of the majority of scientific and technological personnel and staff members' families at ordinary times.
