Automated Venlo - type glass greenhouse with wet - curtain fan cooling system and carbon dioxide supplementation system

The glass panels have high transparency, providing a clear environment inside the greenhouse. They are resistant to chemical corrosion, making them suitable for environments where fertilizers and pesticides are frequently used. The glass is a rigid material, ensuring the stability of the greenhouse structure.

Allows for precise control of the internal environment, which is beneficial for the cultivation of high - value crops. Has a long service life, often lasting for decades with proper maintenance. The high light transmittance ensures that crops can carry out photosynthesis efficiently.

Support systems

Common Methods of CO₂ Supplementation: One method is to burn carbon - based fuels like natural gas, propane, or kerosene. This not only produces CO₂ but also generates heat, which can supplement the heating system.

However, incomplete combustion or contaminated fuels may harm plants. Another common method is to use compressed CO₂ gas. The CO₂ is in a compressed liquid form, which vaporizes through a CO₂ vaporizer and is distributed through pipes in the greenhouse.

Benefits for Plant Growth: CO₂ supplementation can significantly enhance photosynthesis, thereby promoting plant growth and increasing biomass production. It can also reduce transpiration, improve water - use efficiency, and help plants better adapt to water - stressed conditions.

In addition, it can accelerate root and shoot growth, enabling plants to absorb more nutrients from the soil, but at the same time, it may be necessary to increase the fertilizer supply accordingly.
