do perus potatoes have the right stuff?秘鲁的土豆能接受宏观试验吗?thats the question scientists will be asking in Lima next month,When a selection of tubers will begin undergoing tests to determine whether theyer下个月科学家们在秘鲁的大城市利马回答的问题。被选定好的土豆块茎有望拒绝接受,NASA,the us space agency,IS Conducting the Pioneering Experiment together with Limas International Potato Center(CIP美国航天局They will cultivate a hundred selected varieties already subjected to rigorous evaluation in extreme,Mars-like conditions that coullOf the selected candidates,40 are native to the Andes mountains,conditioned to grow in different ecological zones,Withstand sudden被选为土豆的有40种是安第斯山脉出生的品种。这些品种生长在不同的生态地区,对气候的突然变化具有抵抗力,可以在岩石多的旱季土壤中生长繁殖。

the other 60 are genetically modified varieties able to survive with little water and salt . they are also immune to viruses。其他60种土豆都是转基因品种,所以有必要,而且这些品种也是对病毒免疫系统的。those that pass the tests must meet A final criterion-they must be able not only to grow well on mars but also reproduce in large quantities Were alms参与美国航天局这个巨大项目的秘鲁裔宇宙生物学家胡里奥巴尔迪维亚席尔瓦表示:“精选土豆中很多品种不会通过测试。

”科学家们还期待通过这项实验找到适合在恶劣环境下生长的土豆种类,帮助解决地球人口的饥饿和营养不良问题。We must be prepared for the future,said viro logist Jan kreuze,a scient ist at CIP . to respond to desert ification,Rising Temperature and“我们应该为未来制定计划。

”国际土豆中心的科学家扬克鲁斯说。”计划应对荒漠化和气候温暖、盐分低的土壤.”Vegetable of the future未来蔬菜the soil in la joya pampas-a sector of the ataca ma desert in southern Peru thats considered one of the driest places on en位于秘鲁南部阿塔卡玛沙漠的潘帕斯德拉霍亚地区被指出是地球上最干旱的地区之一,那里的土壤与人们在火星上找到的非常相似。

the scientists plan to transport 200 pounds(100 kilos)Of it to a CIP laboratory in Lima that will simulate the complex Martian atmosphere科学家计划将约200磅(100公斤)的土壤运往利马国际土豆中心的实验室。在那里,他们将模拟火星上以二氧化碳为主的简单大气环境,并将土壤暴露在极端紫外线下。well have more concrete results in one or two years,valdi via said,adding that it will take more than five years to launch an unmanned mission“The potential future space crop is also one of The oldest。

土豆是有可能占领宇宙的作物,也是地球上最古老的作物之一。records of potato cultivation date back to 2500 BC,when the indigenous ay Mara Indians farmed it in modern-day Peru and Bolivia。土豆种植的说明可以追溯到If the varieties selected for next months experiment dont adapt to the desert soil,the researchers will introduce nutrients and subjectsIf that doesnt work,valdivia said,well administer a new method the CIP is using called aeroponics。

瓦尔迪维亚说:“如果是这样,我们就不会使用国际土豆中心。The technique,used for cultivating plants without soil,Would expose roots inside a sphere or cube that is sprayy植物的根放在球体或立方体容器上的无土栽培技术,容器里已经洒了营养剂,内置了清除毒素的机制。In future years,NASA plans to build a mars research center in the Peruvian desert。

今后,美国航天局计划在秘鲁沙漠建立一个火星研究中心。it would create a perfect replica of the Martian landscape and atmosphere for future research into space farming that could serve manned missions to MMO该研究中心为了今后的宇宙栽培研究,将仔细恢复到火星的地形和大气状态。

宇宙种植将为观测火星等其他太阳系行星的载人任务获得补给。
