Greenhouse soilless cultivation is a modern agricultural technique that involves planting plants in an environment without soil, using nutrient solutions or specific substrates to provide the plants with the necessary nutrients and water. This technology has multiple advantages and application modes.
Basic principles and methods of soilless cultivation.

The core of soilless cultivation technology is to replace traditional soil cultivation methods by directly using nutrient solutions or substrates to meet the needs of plant growth. The basic steps include preparing nutrient solution, selecting appropriate matrix, setting up the liquid supply system, etc. For example, in a glass greenhouse, plant roots are immersed in containers filled with nutrient solution, thereby avoiding soil diseases and accelerating crop growth and increasing yield.

Applicability of greenhouse
There are various types of greenhouses suitable for soilless cultivation, such as spring and autumn greenhouses, winter warm greenhouses, continuous film greenhouses, continuous glass and solar panels, etc. These greenhouses are usually equipped with external shading systems, internal shading systems, wet curtain fan forced ventilation cooling systems, top ventilation systems, heating systems, and power distribution/control systems to achieve highly automated and intelligent management

Technical features and advantages
Reducing pests and diseases: Due to the non use of soil, soilless cultivation can effectively prevent the spread of pathogens and insect eggs in the soil, reduce the use of pesticides, and thus reduce environmental pollution.
Improve resource utilization efficiency: soilless cultivation does not require tillage, plowing, weeding and other operations, saving labor and effort. Meanwhile, by regularly and quantitatively supplying nutrient solution through the liquid supply system, waste can be avoided and the utilization efficiency of water resources and fertilizers can be improved.

Efficient production: The combination of intelligent greenhouses and soilless cultivation technology can significantly improve production efficiency through efficient water circulation systems and precise nutrient management. In addition, utilizing industrial waste heat and carbon dioxide to provide heat sources for greenhouses and meet the needs of crop ventilation can further achieve energy conservation and emission reduction.
Application examples

In practical applications, many greenhouses have started using soilless cultivation equipment for the cultivation of hydroponic vegetables, hydroponic flowers, and other plants. For example, a demonstration experiment of high and stable yield soilless cultivation of string tomatoes was conducted in a glass greenhouse in the Sunqiao Agricultural Park in Shanghai, and satisfactory results were achieved
