Application and advantages of greenhouse soil-less cultivation technology

Soilless cultivation technology is a modern agricultural production method, especially suitable for greenhouse environments. It provides a more efficient production method by using water, nutrient solution or solid substrate to cultivate plants instead of traditional soil.

HydroponicsDeep Water Culture (DWC)

In the DWC system, plant roots are suspended in a nutrient solution, and the roots are completely immersed in the oxygenated nutrient solution. An air pump is used to increase the oxygen content in the water to promote root respiration and growth. This system is simple and easy to operate, suitable for small greenhouses and beginners.

Nutrient Film Technique (NFT)

The NFT system uses a thin film of nutrient solution to flow over the roots of plants, ensuring that the plants can continuously absorb water and nutrients. This system requires good management to prevent the roots from drying out or being overly wet, and is suitable for vegetables that grow faster, such as lettuce and spinach.

Floating Raft System

Floating Raft System plants are planted on foam boards or other floating materials floating on nutrient solution, and the roots hang freely in the nutrient solution to absorb the nutrients and oxygen they need. It is often used for leafy crops such as lettuce and coriander.

Substrate CultureDrip Irrigation

The drip irrigation system delivers nutrient solution directly to the roots of plants through drippers to ensure uniform distribution of water and nutrients. Its advantages are water saving and high efficiency, and it is suitable for large-scale greenhouse cultivation.

Subirrigation

In the submerged irrigation system, the roots of plants absorb the nutrient solution placed below through capillary action. This method reduces water evaporation and nutrient loss, and is suitable for the cultivation of potted plants and small crops.

Automated Irrigation Systems

Automated irrigation systems automatically adjust the supply and frequency of nutrient solution through sensors and control systems to ensure that plants are always in the best growth state. They are suitable for large-scale commercial production, reduce manual intervention, and improve production efficiency.

Aeroponics

Aeroponics technology suspends plant roots in the air and regularly sprays nutrient solution mist particles to provide sufficient oxygen and water, promote rapid growth and high yields, and is suitable for high-value-added crops such as medicinal plants and strawberries.

Vertical Farming

Vertical farming maximizes the use of the vertical space of the greenhouse by planting plants on multi-layer shelves. Combined with hydroponic or aeroponic systems, it can significantly increase the yield per unit area, which is particularly suitable for urban agriculture and high-density planting.

A-Frame Systems

A-Frame systems are a form of vertical cultivation where plants are planted on an A-shaped structure for easy management and harvesting. They are suitable for growing leafy vegetables and herbs, saving space and increasing yields.

Rooftop Farming

Rooftop farming provides an opportunity to use the space above a building for agricultural production. Combined with soilless cultivation technology, it can produce fresh vegetables and fruits in urban centers, reducing transportation costs and environmental impact.

Supporting TechnologiesClimate Control Systems

The climate control system in a greenhouse is critical to the success of soilless cultivation technology. Automated climate control systems can adjust temperature, humidity and light to ensure that plants grow under optimal conditions.

● Supplemental Lighting - In areas or seasons with insufficient light, the use of LED supplemental lighting can provide the light needed for plant growth. Modern LED lighting systems can adjust the spectrum according to the growth stage of the plant to optimize photosynthesis.

● Nutrient Management - Nutrient management in soilless cultivation requires precise control. The automated nutrient supply system can adjust the composition and concentration of the nutrient solution according to the needs of the plants to avoid excess or insufficient nutrients.

● Water Quality Management - Water quality management is equally important in soilless cultivation. The pH and EC value (electrical conductivity) of the nutrient solution need to be regularly monitored and adjusted to ensure that the plants can optimally absorb nutrients.

● Pest and Disease Management - Although soilless cultivation reduces the risk of soil-borne diseases, effective pest and disease control measures are still needed. A combination of biological control, physical control and a small amount of chemical control can be used to ensure the healthy growth of plants.

Monitoring and Management System

● Data Monitoring - The greenhouse environment and plant growth conditions can be monitored in real time through sensors and IoT technology. The data monitoring system records information such as temperature, humidity, light, and nutrient concentration to help farmers make timely adjustments and improve management efficiency.

● Integrated Management Systems - The integrated management system integrates various control systems of the greenhouse and realizes automated management through a central control platform. Farmers can remotely monitor and control various parameters of the greenhouse through mobile phones or computers to improve production efficiency and management level.
