Although the impact of the epidemic on our lives is not as serious as in previous years, there are still many things worth thinking about during the epidemic. The lack of food supply due to the interruption of the supply chain has left a psychological shadow on many people. It is urgent to change the traditional agriculture.Under the catalysis of various reasons, vertical farming technology has entered people's vision.
What is vertical farming technology?
Vertical farming technology is a new indoor planting technology that is different from traditional agriculture. It is a farm that plants crops in pallets and other modular structures. These structures can be stacked vertically to maximize the use of limited space.The unique feature of vertical farms is that they do not need soil, which greatly alleviates the current shortage of land resources. Vertical farming technology is mainly hydroponics and aeroponic, and hydroponics is the most widely used. By re-collecting and recycling water, vertical farms can reduce water waste caused by poor irrigation or evaporation, which will reduce water consumption by 70% to 95%.
What are the advantages of vertical farming?
At present, cultivated land resources and water resources are very scarce. Although China is vast, there are many people and few land, and cultivated land resources are scarce. The characteristics of cultivated land resources in China are "three less", that is, less per capita cultivated land, less high-quality cultivated land, and less reserve resources of cultivated land. Compared with traditional methods, indoor vertical farming technology much less land space. Vertical farming technology have their advantages.
Effectively reduce the use of space.
Vertical farming can enable us to plant more crops in a smaller space. In the same land space, the output of vertical farms is about 100 times that of traditional farms. In addition, the use space of vertical farms is not limited. Planting can be started in both densely populated urban centers and resource-poor Gobi. This means that agricultural products can be planted in places close to people's homes. For people in cities and towns, even if there is no farmland like rural areas, they can eat fresh vegetables.
Reduce the harm of using pesticides to environmental pollution.
Vertical farming do not contain pesticides and herbicides because they do not use soil to plant and reduce the harm of diseases and pests, effectively reducing the pollution harmful to the environment. In order to increase the yield of traditional soil planting, a large number of pesticides and growth hormone will be used, resulting in the residual of some harmful substances harmful to human health.
Where will vertical farming technology go in the future?
These advantages show that vertical farming are very suitable to cope with any increase in demand for things that may be brought about in the future. The most obvious advantage of vertical farming is the full use of resources, space and time. Vertical agriculture saves water, does not need to worry about disease and insect disasters and natural disasters. It can harvest 365 days a year, and can greatly improve the crop productivity of the same area of land. Some researchers describe vertical agriculture as follows: crop yield is 390 times higher, water consumption is 95% less than that of general planting, no sunlight, no soil, no pesticide, and no agricultural pollution.
