Wonderful sweet potato, not grow in the soil, but grow in the air, absorb nutrients from the air?

When a seed falls into the soil, it will take root and sprout. The old idea that green plants cannot be separated from soil layers is unshakable in everyone's mind. But now, more and more advanced scientific and technological progress has made many magical things come true. Generally, fruits grow on trees, but their roots are deep soil. But there are also ingredients such as potatoes and carrots, such as sweet potatoes. We all eat its underground stems, so eating this part grows in the soil. If you put the sweet potato in the "treetop" like an apple, it is really incomprehensible, but such a magical thing does appear.

Sweet potato is also called sweet potato. It grows in the soil and absorbs nutrients from the soil according to its roots. If this part is exposed to the air, it can't digest and absorb nutrients. But is there a wonderful sweet potato that will soon grow in the soil and absorb nutrients from the air?

But it is not a species, but a planting method. Common sweet potato can grow and develop normally without soil under the condition of ensuring rich nutrition and water supply after being cultured in cell culture solution.

Growing sweet potatoes in this way has many advantages. You can tell whether the sweet potato exposed to the field of vision is ripe or not. That kind of picking method is convenient and fast, unlike the traditional picking method, the growth status of sweet potato will not be known until it is dug.

Moreover, after the traditional sweet potato was uprooted, some of its leaves basically lost their functions and needed to be replanted with new crops. In the form of planting sweet potatoes in the sky, you only need to save potato seedlings to produce potatoes several times.

Planting sweet potatoes in the sky produced an interesting picture. A large number of sweet potatoes are hung high, thinking that they are drying. But for the new planting method, everyone is most concerned about eating. As long as the nutritional components meet the requirements, the sweet potato planted in the sky can also be cultivated as in the traditional soil layer, and the taste and nutritional components are not easy to differ too much.
