LED plant lighting to solve the Antarctic expedition fresh vegetable supply problems

Jiangxi network China fresh vegetable supply has been plagued China's Antarctic expedition of the "old", especially the Zhongshan Railway Station, required a year of vegetables by the "Snow Dragon" from China and Australia and other countries by way of supply, not only costly, and the storage time is limited. When the Antarctic into the long winter, expedition members can only rely on several kinds of vegetables such as cabbage wintering.

Therefore, small tomato green lettuce, fresh cucumber, was the excellent singing or polished writing Antarctic expedition team, the "luxury" dream of. Therefore, Chinese thirty-first Antarctic expedition during 2014 as the national science and technology support program of the Antarctic extreme environment of greenhouse vegetable production key technology research and demonstration project, in the Zhongshan Railway Station and Great Wall Railway Station and carry out initial research experiment. Now thanks to advanced greenhouse cultivation techniques such as LED lighting plants, this dream has become a reality in China Antarctic expedition.

Vegetable greenhouse Laboratory

According to the thirty-first National Antarctic expedition team members Wang Zheng introduced, laboratory vegetable greenhouse is a 16 square meters of the room, the whole greenhouse soilless culture, vegetable cultivation by automatic control system automatic control irrigation pump, temperature and humidity, light and nutrient solution cultivation. For example, in the computer under the control of LED, a plant growth lamp can automatically adjust the lighting according to the growth of vegetables; automatic irrigation system every hour to sink into the nutrient solution; when the room humidity is lower than 70%, humidification system will spray water into the room.

In addition, in order to promote the growth of vegetables, vegetables greenhouse laboratory 24 hours a day to play light music. The treatment of vegetables is much higher than the investigation team. Wang Zheng said with a smile.

Because the growth cycle is short, easy to cultivate, and the yield is large, the main cultivation of vegetables in the Zhongshan Railway Station is lettuce, cabbage and cucumber. Wang Zheng said. In cucumber, for example, an average of 2 days of cucumber vine can harvest a cucumber, if planted with a strain of 20, you can ensure that the 18 players during the winter to eat fresh cucumber every day.

In addition, also try to grow chili peppers, okra, tomato and watermelon, but the yield is too low, not successful. Therefore, members of the team to eat the most is the lettuce, rinse up taste very good. Cabbage fried after the amount is very small, so the main soup. Cucumber should not be eaten raw, mainly slices and fungus cooked vegetables together.

Wang Zheng also told reporters that there is a good thing to grow vegetables in the Antarctic, it is no pests, no need to fight pesticides. However, the Antarctic greenhouse by day and night to burn gasoline heating to resist polar cold, even so, energy consumption is still much lower than shipping.

Wang Zheng says it takes a month to grow vegetables from seeds to grow. Therefore, it is necessary to plan the stage and batch, do a good job of vegetable replacement and rotation.

"Cook four meals a day in antarctica. Wang Zheng said that the Antarctic food all rely on foreign transport, meat, vegetables are very scarce, the Zhongshan Railway Station successfully cultivated vegetables, so many foreign expedition team envy. Therefore, they often come to Zhongshan Railway Station rub rice.

According to reports, last year, the Great Wall Railway Station was built in the world's first sunshine greenhouse, relying on plant growth lights and other greenhouse cultivation techniques successfully planted fresh vegetables.

It is the first time in the history of China's Antarctic Zhongshan Railway Station to eat fresh vegetables. "China Antarctic research station can provide fresh vegetables caused international concern, because of the home grown vegetables can mean the country come to the forefront of the world in the health and survival ability, can greatly prolong human health residence time in the antarctic.
