Hydroponics is the science of growing plants without the use of soil. It is also known as "Soilless culture". 
 
     In traditional agriculture where plants are grown in soil, nutrients and water exist randomly, and often plants need to expend a great deal of energy to grow long roots to search for water and nutrients. By expending this energy, plants do not grow as fast as they could. However in a hydroponic system, a plant doesn't have to expand any energy growing long roots in search of it. In addition, growing plants in hydroponics requires less water, less space, and pests and diseases are more easily controlled and prevented.
   In aerosol cultivation, vegetables are hung in a cultivation device, such as a tank, a box or a bed, the roots of vegetables are exposed inside the cultivation device, and the nutrient solution is atomized into small mist droplets by a spraying device, which are directly sprayed on the surface of plant roots.

The advantages of aerosol cultivation are: firstly, it solves the contradiction between water and gas in the root system of soilless cultivation of vegetables; Secondly, it is easy to control automatically and carry out three-dimensional cultivation, so as to improve the utilization rate of greenhouse space and multiply the yield of vegetables.
At present, vegetable farmers mostly cultivate leafy vegetables and melons and fruits with aerosol, and harvest the original aboveground branches and leaves. It is more suitable to adopt aerosol cultivation to harvest roots or various tuber and rhizome plants, such as lily, potato, sweet potato, etc.
  
Advantages of aerosol cultivation:
1. Like other leafy fruits and melons, the formation speed of biological yield of these crops cultivated by aerosol is greatly accelerated, which is several times that of soil cultivation.

2. The underground part can be inspected at any time, which is more conducive to observing and studying the development of the underground part, and provides more field data for people to formulate management measures and study cultivation techniques. For example, the effect of spraying paclobutrazol on potato tuber development is more convenient and intuitive than the observation of cultivation in soil.

3. When harvesting underground parts, most of the locally cultivated plants are excavated, resulting in different products with different sizes and different qualities. However, when using aerosol culture, harvesting underground parts, just like picking melons and fruits, can be harvested in batches and selectively. The harvested tuberous bulbs can achieve the consistency of size and quality. By adopting this method, the overall economic yield will be increased several times compared with one-time harvest, which may waste less nutrition with plants and can be

4. Aerosol culture is more convenient in operation and production. It can check the development of underground parts at any time, and adjust and control the liquid at any time according to the development situation. More importantly, the underground development is completed in the air. Its morphological development is not affected by the mechanical resistance of soil, and its individual development is extremely uniform, showing the relative consistency of morphology. For example, potatoes show the same round or oval shape, which is really like eggs of the same size. The management labor is also greatly reduced, and there is no need to weed and loosen soil, raise soil and protect soil moisture. Roots and tubers can develop without any barriers in aerosol, which can maximize the potential of their varieties, and the yield is several times or dozens of times that of ordinary soil cultivation.
  

 

 

 

The word hydroponics comes from Greek, which means "cooperation with water". It is a method of growing plants in nutrient-rich liquid instead of soil. This operation can be done outside warm weather or indoors all year round. It has many advantages, including: no weeding, rapid growth, high yield in narrow space, no small animals stealing crops, clean vegetables, easy harvest, consistent quality, no insects or diseases related to soil, etc.
