Soilless cultivation of vegetables is also called hydroponics and nutrient solution cultivation. Soilless cultivation technology of vegetables makes the production of crops completely out of the soil and not limited by soil conditions. Vegetables are cultivated with certain equipment and substrates. All the nutrients needed for soilless cultivation of vegetables are supplied by nutrient solution, so crops can get complete, sufficient and suitable nutrients, and the nutritional conditions have been greatly improved.

Soilless culture technology is one of the high-tech agricultural technologies. It is characterized by replacing natural soil environment with artificially created root microenvironment, and cooperating with scientific and automatic management technology to maximize the production potential of crops and realize high yield, high quality, high efficiency and low pollution.

Soilless culture is the product of the development of science and technology to a certain stage, and it is the organic combination of modern science and technology and agricultural production. The popularization and application of soilless culture technology in agriculture will make the traditional agricultural production leap, from the passive state of relying on nature, soil conditions and the sky to the modern, industrialized, automated and high-quality vegetable production relying on science and technology and getting rid of the restrictions of land conditions. It can be seen that the soilless cultivation technology of vegetables in China has a good development prospect in 2 1 century.
