<Anchor> In



places with low sunlight, such as the Antarctic Sejong Station, it was not possible to grow fruit vegetables such as cucumbers and zucchini, so only leafy vegetables such as lettuce were cultivated.



Reporter Park Chan-beom on the report.



<Reporter> This



is the movie'Martian' about the survival of an astronaut isolated on Mars.



The protagonist's survival food is potatoes grown directly with artificial lighting.



However, most of the vegetables grown under artificial lighting on Earth are leafy vegetables that grow rapidly with little light.



Fruit vegetables such as peppers and tomatoes need stronger lighting and a lot of water, so they have not received the attention of indoor agriculture, but domestic researchers have developed a next-generation'plant factory' that can grow two types of vegetables at the same time with the same lighting energy.



[Ahn Se-woong / Researcher at the Academy of Horticultural Sciences: LED light is being used to replace sunlight.] We have



improved the cultivation environment such as temperature so that fruit vegetables grow fresh even with weak lighting.



Fruit vegetables grown only with artificial LED light can be harvested in 50 to 70 days, and leafy vegetables in 30 to 40 days.



This plant factory is first moved to the Antarctic King Sejong Station.



The base crew has grown only leafy vegetables such as lettuce and garland chrysanthemums, but now fruit vegetables such as peppers, tomatoes and zucchini can be grown indoors.



[Lee Jun-hyuk/Head of Antarctic Sejong Station Facility Maintenance Manager: Seeing green vegetables is a pleasure.] The



Rural Development Administration expected that the productivity of indoor agriculture or urban agriculture, which is having difficulty in supplying this technology, will also greatly increase.
