近20年来,在非洲纳米比亚的海岸线附近的沙漠绿洲中,出现了数以万计的怪圈。尽管怪圈周围杂草茂盛,怪圈内却是寸草不生。当地人认为那些怪圈是被精灵诅咒的地方,甚至不敢进入怪圈内。因此,这些怪圈被称为“精灵怪:圈”。是泥土有放射性,阻止植物生长吗?是地下有白蚁,将植物种子全部吃光了,还是怪圈泥土中带有某种有毒物质?科学家将怪圈中的泥土用仪器进行分析,排除了第一种和第三种可能性。2012年,美国生物学家沃尔特在这里没有挖掘到白蚁的巢穴。第二种可能性也被否决。难道怪圈真的是“精灵”的杰作?德国生态学教授诺伯特·于尔根斯也来凑热闹。结果 Tens of thousands of strange circles have emerged in desert oases near the coast of Namibia in Africa in the past 20 years. Although the weeds around the vicissitudes of life, it is abrupt within the circle. Locals think those are the curses of the wizard is cursed, and even did not dare enter the cycle. Therefore, these circles are called “Elf strange: circle ”. Is the earth radioactive, to prevent the growth of plants? Are there underground termites, all the seeds eaten plants, or the strange circle of dirt with some toxic substances? Scientists will cycle the soil with instruments for analysis, ruled out the first And the third possibility. In 2012, American biologist Walter did not tap into the nest of termites here. The second possibility is also rejected. Is it really a “geek” masterpiece? Norbert Jurgenz, professor of German ecology, came to join in the fun. result
