People have been seeking to grow more food in less space and less soil. At present, vertical farming in modern sense is developing rapidly all over the world.The vertical farm will adopt a more advanced aeroponic system, which uses the atomizer to produce the mist and directly act on the plant roots.
The plant root system in the aeroponic system environment is free to extend, and oxygen, water and nutrition are sufficient, which is one of the best cultivation modes for plant rapid growth. The plant roots in the aerosol environment are completely in the environment of water, air and fertilizer integration, which can give full play to the growth potential of plants.
There are many advantages of vertical aeroponic system. It is of great help to realize the planting freedom of farmers.
Compared with field planting, the water consumption of soilless cultivation can even be reduced to 1/10 of the former, because the water and nutrient solution used for planting will be recycled, filtered and reused, rather than finally lost in the natural environment.The water efficiency and nutrient efficiency of aeroponic system are very high, because the roots can obtain these water and nutrients faster, and the specific plants do not need to compete with other plants for water and nutrients. This means that the use of vertical farms can greatly reduce the water and fertilizer needed to grow food.
At the same time, the closed and controlled environment of vertical farms can help to prevent the occurrence of diseases and pests, thus reducing the demand for pesticides.Vertical aeroponic system can limit the spread of diseases between crops. Because the contact between crops is reduced, and each spraying pulse can be sterile. In traditional soil planting, diseases can spread throughout the growth medium and infect many plants. A significant advantage of Vertical aeroponic system is that if a specific plant does have disease, it can be quickly removed from the plant support structure without disturbing or infecting other plants.
Vertical aeroponic system can effectively alleviate the shortage of cultivated land.Soilless cultivation technology makes crops completely separated from the soil environment and not limited by soil quality and water conservancy conditions. At present, there are many deserts, wastelands or areas difficult to cultivate on the earth, and land resources are still very scarce. Soilless cultivation breaks away from the restriction of land, and in addition, it can also grow vegetables and flowers on the plane roof of abandoned factories and buildings in the city, which virtually expands the cultivation area.
Soilless cultivation is the common impression of hydroponics for vegetables. In fact, the so-called "soilless" includes not only hydroponics and aeroponic, but also all cultivation methods without soil in a broad sense. Its emergence has made agricultural production more possible to be accurately controlled. Since then, planting has freed itself from the shackles of the land and opened up an oasis in barren land with drought as desert and cold as the South Arctic.Vertical agriculture indicates that our food in the future will be planted in a small space in our city or under our feet.
