科學(xué)家在南極溫室首次收獲綠色蔬菜。

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.

雖然美國國家航空航天局已成功在國際空間站種植綠色植物,但德國農(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,有一天可能會在火星或月球上種植。
