What is the meaning of soilless cultivation

"Soilless Culture" can be translated as non-industrial cultivation, pollution-free cultivation, aseptic cultivation. At present, it is important to understand the original meaning of "Soilless Culture", otherwise it is not conducive to the development of jobless cultivation. In short, "Soilless Culture" means aseptic disinfection. If you do not understand its meaning, mistakenly use horse dung, human dung and urine, peat, cottonseed shell, moss and other humic substances as substrates or nutrients, that is wrong.

A.A.Steiner, the chief tribute of the International Association for soilless Culture, defined soilless cultivation as vegetative cultivation. These have long been widely used in the United States, Japan, Taiwan, Hong Kong and Macao.

The following equations can be expressed:

Soilless Culture=Hydroponics

Non-working (aseptic) cultivation = nutrient solution cultivation, which can be divided into the following forms: 1. Water culture; 2. Air culture; 3. Gravel culture; 4. Sand culture; 5. Vermiculite culture; 6. Rock wool culture; 7. Fluctuating fiber culture.

"Soilless Cuture" (soilless, aseptic cultivation) refers to the use of inorganic nutrient solution to provide plants with nutrients necessary for growth, instead of providing nutrients to plants from soil and organic matter.

In soilless and aseptic cultivation, the nutrient solution can be sprayed directly to the root system (air culture), or the plants can be directly inoculated in the flowing soilless nutrient solution (hydroponics), or the plants can be cultivated directly with the sterilized microporous inorganic ore and inorganic fiber as the matrix. As for "vermiculite + horse dung" and "sawdust + human dung and urine", they do not belong to the category of modern soilless cultivation technology.
