Wang Zheng, Shangrao People's Hospital Department of orthopedics doctor. In October 30, 2014, he was invited by the State Oceanic Administration to travel from Shanghai to the south pole to participate in the thirty-first National Antarctic expedition mission (that is, the task of overwintering the Zhongshan Railway Station). At the Chinese Antarctic expedition Zhongshan Railway Station, he not only visited the doctors, but also successfully planted vegetables, contributing to the nutrition and health of Antarctic expedition members. This is the first time that China has successfully cultivated vegetables in Antarctica.
in January 24th of this year, Wang Zheng successfully completed his mission and returned to Shangrao. Recently, Wang Zheng told reporters about his unforgettable story of planting vegetables in Antarctica.

to make the dream of eating fresh vegetables a reality
the supply of fresh vegetables has been a problem that has plagued China's Antarctic science examination. Especially at Zhongshan Railway Station, the vegetables needed for one year were recharged by the country and Australia by the "Snow Dragon", not only high in cost, but also by the country and Australia. And the storage time is limited. When the south pole enters a long winter, the members of the scientific research team can only rely on several limited vegetables such as Chinese cabbage to survive the winter.
therefore, green lettuce, fresh cucumber, pearl and round tomatoes are among the most luxurious dreams of Antarctic expedition members. To this end, during the thirty-first Chinese Antarctic expedition, as one of the national science and technology support program of 2014, "the key technology research and demonstration of the vegetable production in the extreme environmental greenhouse of Antarctic environment", the preliminary research experiments were carried out at the same time at the Zhongshan Railway Station and Great Wall Railway Station as well.
today, thanks to the advanced greenhouse cultivation technology, this dream has become a reality in the China Antarctic scientific research station. Wang Zheng, one of the players behind the scenes. He recalled: "every member of the team has to take charge of some life matters in addition to finishing his job. I was assigned to the vegetable room, breeding and planting vegetables for everyone to eat. There are different kinds of vegetables grown in different gardens. They are mainly cultivated by light and heat, and seeds are transported from Shanghai in advance.
soil free cultivation computer control automatic irrigation
"after getting up in the morning to the vegetable greenhouse laboratory, check the control system is normal, there is no leakage on the ground. After breakfast, pick vegetables and send them to the kitchen. Check in the morning and afternoon to see if there is any need to replace the vegetables. This is a diary of Wang Zheng planting vegetables in Zhongshan Railway Station, Antarctica.
Wang Zheng told reporters that the vegetable greenhouse laboratory is a room of 16 square meters. The whole greenhouse adopts the technology of soil free cultivation, and the automatic control system of vegetable planting automatically controls the irrigation pump, temperature and humidity, the cultivation lamp and the nutrient solution. For example, under the control of the computer, the LED plant growth lamp can automatically adjust the length of the lighting according to the growth of the vegetable; the automatic irrigation system inject the nutrient solution into the sink every other hour; when the room humidity is below 70%, the humidifier system will spray the water mist into the room.
in addition, in order to promote vegetable growth, light music is played 24 hours a day in the greenhouses laboratory. "The treatment of vegetables is much higher than the inspecting team." Wang Zheng said with a smile.
lettuce, cabbage and cucumber have no insect pests
"because the growth cycle is short, it is easy to grow, and the yield is great. The main vegetables in Zhongshan Railway Station are lettuce, Chinese cabbage and cucumber." Wang Zheng said. Taking cucumber as an example, an average cucumber vine can harvest a cucumber in 2 days. If 20 plants are planted, 18 players can eat fresh cucumbers every day during the winter. Besides
, pepper, okra, tomato and watermelon were also tested, but the yield was too low to be successful. Therefore, the most important thing that the players eat is lettuce, which is delicious. Chinese cabbage is very small after frying, so the main thing is to make soup. Cucumber can not be eaten raw, mainly sliced together with fungus to make cold dishes.
Wang Zheng said that it takes a month to grow from seeds to grown vegetables. Therefore, we must plan the stages and batches to make vegetable replacement and rotation.
chef secretly picked cucumber to make him angry.
"because I planted it with my own hands, so I am very sentimental about vegetables." Wang Zheng said that once the chef did not inform him, he picked cucumber and made him angry. For this reason, during the meal, Wang Zheng emphasized to everyone that vegetable picking has strict standards, otherwise it will cause waste of resources. For example, cabbage and lettuce grow to more than 15 centimeters to pick, otherwise it will affect growth. Cucumber should be picked up when it grows to about 15 centimeters, otherwise it will be wasted. If more than 15 cm is not picked, it will affect the normal growth of other cucumbers.
the foreign members of the team are very admired for the success of the rice
vegetable cultivation, which makes the food of the team members improve and help the players to improve their physique. In addition, in the free time, coming back from the ice and snow outside, you can see a house of green vegetables, which is a great enjoyment, sitting in a vegetable greenhouse laboratory and listening to music to relax.
"make four meals a day in the Antarctic." Wang Zheng said that the food of the Antarctic was transported all by foreign countries, the majority of the meat, the lack of vegetables, the successful cultivation of the vegetables at the Zhongshan Railway Station, so that many foreign members of the scientific research team envied. As a result, they often come to the Zhongshan Railway Station to scrape their meals.
Jiangxi doctor created China's first
professor of Nanchang University and a guest professor at the national Polar Research Center. It was the first time in the history of the Chinese Antarctic investigation to eat fresh vegetables, and its cultivation was from the hands of doctor Wang Zhengzhi. Since then, doctors in Jiangxi have created the first China.
"China's Antarctic survey station can provide fresh vegetables for international attention, because the self produced vegetables in the Antarctic means that the country has come to the forefront of the world's healthy living ability in the Antarctic, which can greatly prolong the healthy living time of human beings in the Antarctic." Professor Yu Wanxian told reporters.
