If the varieties selected for next month's experiment don't adapt to the desert soil, the researchers will introduce nutrients and subject them to radiation.
下个月,这些选出的土豆品种将参与实验。如果这些土豆不能适应沙漠土壤,那么研究人员将对它们施以养分并将其置于紫外线照射下。
"If that doesn't work," Valdivia said, "we'll administer a new method the CIP is using called aeroponics."
瓦尔迪维亚说:“如果还是不行的话,我们会采用国际马铃薯中心使用的一种名叫‘气栽’的新方法。”
The technique, used for cultivating plants without soil, would expose roots inside a sphere or cube that is sprayed with nutrients and contains a system for removing toxins.
这是一种无土种植技术:将植物的根部置于球体或立方体容器中。容器中原本已喷洒了营养剂,并内置了一套去除毒素的机制。
