Ultrafine and nano-scale bubbles enhance efficient oxygenation in greenhouse facilities.
2026-06-15
The ultramicro‑nanobubble generation device, serving as the core oxygenation unit of a fully automated hydroponic greenhouse facility, is providing critical support for large‑scale production at a renowned agricultural technology company in Shandong. In this state‑of‑the‑art plant, the nutrient‑solution recirculation system supplies all the water and nutrients required for crop growth, while the ultramicro‑nanobubble generator is seamlessly integrated into this vital component, precisely delivering dissolved oxygen to the nutrient solution and effectively eliminating the risk of root hypoxia and root rot.

Compared with conventional aeration methods, this technology offers distinct advantages: bubble diameters are reduced to the nanoscale, enabling extremely long suspension times in water and delivering a geometrically enhanced oxygen-transfer efficiency. It sustainably maintains dissolved‑oxygen levels in the nutrient solution at near‑saturated concentrations, ensuring that even in high‑temperature, high‑humidity greenhouse environments where dense root systems rapidly consume oxygen, every plant’s roots can breathe freely and remain vigorously active. Moreover, the charged surface of nano‑bubbles and the micro‑jets released upon their collapse gently cleanse root surfaces and inhibit pathogen proliferation, achieving an integrated triple benefit of oxygenation, root stimulation, and disease prevention. The system operates under fully automated control, requiring no manual intervention, and seamlessly aligns with the intensive production rhythms of fully automated greenhouse facilities, safeguarding the nutrient‑solution system’s vital functions in an efficient, stable, and environmentally friendly manner.
