Scientists in Antarctica have harvested their first crop of vegetables grown without earth, daylight or pesticides as part of a project designed to help astronauts cultivate fresh food on other planets.
作為旨在幫助宇航員在其他星球上培育新鮮食物的項(xiàng)目的一部分，南極科學(xué)家們已經(jīng)首次收獲了他們的不含土，日光或殺蟲劑的蔬菜。
Researchers at Germany’s Neumayer Station III say they’ve picked 3.6 kilograms (8 pounds) of salad greens, 18 cucumbers and 70 radishes grown inside a high-tech greenhouse as temperatures outside dropped below -20 degrees Celsius (-4 Fahrenheit).
德國(guó)Neumayer Station III的研究人員表示，由于外界氣溫低于零下20攝氏度(-4華氏度)，他們已經(jīng)在高科技溫室內(nèi)種植了3.6公斤(8磅)沙拉青菜，18棵黃瓜和70棵蘿卜。
The German Aerospace Center DLR, which coordinates the project, said Thursday that by May scientists hope to harvest 4-5 kilograms of fruit and vegetables a week.
協(xié)調(diào)該項(xiàng)目的德國(guó)航空航天中心周四表示，5月份科學(xué)家希望每周收獲4-5公斤水果和蔬菜。
While NASA has successfully grown greens on the International Space Station, DLR’s Daniel Schubert says the Antarctic project aims to produce a wider range of vegetables that might one day be grown on Mars or the Moon.
雖然美國(guó)國(guó)家航空航天局已成功在國(guó)際空間站種植綠色植物，但德國(guó)農(nóng)業(yè)研究中心的丹尼爾舒伯特說，南極項(xiàng)目的目標(biāo)是生產(chǎn)種類更多的蔬菜，有一天可能會(huì)在火星或月球上種植。
