这使得种子在沙漠泥土中播撒。
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。
To study the water-holding capacities of desert soil and the soil amended with coal ash and sewage sludge, experiments were designed to simulate rainfall and natural evaporation.本文通过模拟降雨及降雨后自然条件下的土壤表面水分蒸发,研究了粉煤灰和城市污泥改良荒漠土壤对持水性能的影响。
