LED grow lighting can cultivate fresh vegetables
Harsh environment also eat fresh vegetables, thanks to the LED and other advanced lighting plants in greenhouse cultivation techniques, within the Chinese Antarctic expedition stood on the establishment of a laboratory greenhouse vegetables now, you can grow fresh lettuce, cucumber, tomatoes and other fruits vegetables, solve the "persistent" problem of the Antarctic expedition.
It is reported that during the first 31 Chinese Antarctic expedition as "extreme Antarctic environment greenhouse vegetable production key technology research and demonstration" project 2014 National Science and technology support program, one of the Great Wall Station and Zhongshan Station at the same time to carry out initial research experiments. Today, the Antarctic Great Wall Station built the world's first sunny conservatory, relying on plant growth lights and other greenhouse cultivation techniques for a successful planting fresh vegetables. Antarctic Zhongshan Station also established a laboratory greenhouse vegetables, the use of LED lighting plants cultivated fresh vegetables.
According to the 31st National Antarctic expedition team Wang Zheng introduced, vegetable greenhouse lab is a 16-square-meter room, the entire greenhouse soilless cultivation techniques adopted by the vegetable-controlled system to automatically control irrigation pumps, temperature and humidity, LED grow lights and cultivate nutrition and so on.
For example, under the control of the computer, LED grow lights can be automatically adjusted according to the growth of vegetables, long time lighting; automatic irrigation system one hour nutrient solution injected into the tank every other; when the room humidity is below 70%, humidification system will Rooms within the spray mist. In addition, in order to promote the growth of vegetables, vegetable greenhouse lab 24 hours a day to play soft music. "Treatment of vegetables is much higher than the investigation team." Wang Zheng said with a smile.
It is reported that the supply of fresh vegetables has been a problem in China's Antarctic expedition "persistent" problem, in particular, the Zhongshan Station, required a year of vegetable alone, "Snow Dragon" from China and Australia through the national supply, not only costly It is limited, and the storage time. Therefore, green lettuce, fresh cucumbers and tomatoes was one of the most Antarctic expedition team "luxury" dream.
Now thanks to plants such as LED lighting and other advanced greenhouse cultivation techniques, the Antarctic Zhongshan Station kinds of vegetables has become a reality in China Antarctic research station. "Due to the shorter growth cycle, easy to cultivate, and the yield, Zhongshan Station, the main cultivation of vegetables are lettuce, cabbage and cucumber." Wang Zheng said. In cucumber, for example, a cucumber vine can harvest an average of two days a cucumber, if planted 20, 18 players will be able to ensure that during the winter eat fresh cucumber on a daily basis. Today, even the foreign expedition team members often come to eat.
