Soilless cultivation
2021-01-22
Soilless cultivation refers to the cultivation method in which water, grass charcoal or forest soil, zircon and other media are used as the substation fixation plants of the root system, and the plant roots can come into direct contact with the nutrient solution.
The nutrient content in soilless cultivation is easy to control and can be adjusted at any time. In places with light, temperature and no soil, such as deserts, beaches and desert islands, it can be carried out with a certain amount of fresh water supply.
Soilless cultivation is divided into hydroponic, fog (gas) cultivation and substitlytic cultivation according to the different cultivation medium.
Hydroponics refers to the cultivation method of plant root system which is in direct contact with the nutrient liquid and does not use the substitut. The earliest hydroponics was the immersion of plant roots in nutrients to grow, which led to hypoxia and, in severe cases, root death.
Hydroponic methods are often used by the nutrient film method, even if a very thin layer of nutrients, constantly circulating through the root system of the crop, not only to ensure the continuous supply of crop water and nutrients, but also to continuously supply the root system of fresh oxygen.
